    The present invention relates to an air conditioning system for an electric transport vehicle. The invention applies in particular to urban electric transport vehicles, these vehicles having frequent stops and therefore having short traction and braking phases.
    With electric transport networks becoming increasingly popular, power grids supplying vehicles can be undersized during peak hours. It is therefore necessary to reduce energy consumption in the electricity transmission networks, in particular consumption peaks.
    Some equipment such as air conditioning systems consume significant electrical energy.
    An air conditioning system has a set of actuators and is configured to maintain climatic conditions in a passenger compartment.
    In general, the actuators comprise, inter alia, a compressor, a fan and heating means such as resistors. It will be noted that the actuators producing heat or cold are actuators consuming significant electrical energy.
    Climatic conditions are represented by a set of parameters, such as temperature, humidity or air pollution.
    Thus, the air conditioning system is configured to maintain the parameters representative of the climatic conditions at predetermined values. For example, they are configured to maintain the temperature of the passenger compartment at a predetermined temperature or set temperature.
    In order to maintain the parameters representative of the climatic conditions at predetermined values, the air conditioning system comprises regulating means which are configured to generate operating commands of the actuators as a function of a set of parameters representative of climatic conditions inside. and outside the cockpit.
    For example, the regulation of the temperature to a predetermined temperature value is implemented depending on the temperature inside and outside the passenger compartment.
    Note that inside a cabin, the rate of CO2 is related to the number of people in the cabin. Thus, in conventional air conditioning systems, the air renewal system must be sized so that the air is renewed when the cabin has a maximum occupancy.
    In a manner known in certain air conditioning systems, the rate of CO 2 inside the passenger compartment can also be taken into account in order to regulate the rate of renewal of the air inside the passenger compartment and thus reduce the energy consumption of the air conditioning system, especially when the occupancy of the passenger compartment is low.
    Thus, depending on the parameters such as the temperature inside or outside the passenger compartment, and possibly CO 2 in the air of the passenger compartment, control means of the air conditioning system generate operating commands applied to the various actuators component of the air conditioning system.
    These operating commands are such that the actuators deliver an average power over a predetermined time interval.
    In order to reduce the consumption of electrical energy in an electric transport vehicle, solutions exist to recover electrical energy in certain phases of the operation or modes of movement of the vehicle, and then to use it in other phases of operation or modes of travel, and in the same vehicle from which the energy is recovered or in another vehicle powered by the same power supply network.
    During the braking phases of electric vehicles not equipped with energy recovery devices, rheostats connected to the vehicle's engines dissipate the electrical energy generated by the vehicle's engines in the form of heat.
    Thus, during this operating phase, the generated electrical energy is recovered instead of being dissipated in rheostats.
    For example, the energy recovered in braking phases is used in traction phases of the same vehicle from which the energy is recovered or in traction phases of another vehicle powered by the same power supply network.
    According to energy recovery techniques, the air conditioning systems of a vehicle can be powered by energy recovered during the braking phases of the same vehicle or of another vehicle powered by the same power supply network. .
    The present invention aims to improve the techniques of reducing energy consumption so as to reduce the peaks of energy consumption of an air conditioning system in an electric transport vehicle. For this purpose, the invention aims, in a first aspect, an air conditioning system for an electric transport vehicle powered by a power supply network, the air conditioning system comprising - at least one actuator producing heat or cold and regulation means configured to generate at least one operating command applied to said at least one actuator as a function of parameter values representative of the climatic conditions, said at least one actuator delivering an average power over a predetermined time interval.
    According to the invention, the regulation means are configured to generate said at least one operating command applied to said at least one actuator in addition to the value of a parameter relating to at least one electric transport vehicle powered by the network. the value of the parameter indicating that electrical energy is consumed by said at least one electric transport vehicle or that electrical energy is produced by said at least one electric vehicle, said at least one control of operation being generated so that the average power delivered by said at least one actuator over the predetermined time interval has substantially the same value as when the regulating means only take into account the parameters representative of the climatic conditions.
    Thus, the control means take into account the climatic conditions, as well as at least one parameter relating to at least one electric transport vehicle for generating the operating commands of the actuators of the air conditioning system of a vehicle.
    It should be noted that the regulation means can take account of at least one parameter relating to the electric transport vehicle in which the air conditioning system is installed or relating to another electric transport vehicle powered by the power supply network.
    Thus, thanks to these characteristics, the operating commands are generated taking into account, in addition to parameter values representative of the climatic conditions, the value of the parameter relating to at least one electric transport vehicle, without modifying the value of the average power delivered by said at least one actuator over the predetermined time interval, relative to the average power delivered by the actuator when only the parameter values representative of the climatic conditions are taken into account.
    The regulating means thus function in such a way as to maintain predefined climatic conditions, that is to say to maintain the value of the parameters representative of the climatic conditions at predefined values, while taking into account at least one parameter relating to a vehicle. electric transport.
    This makes it possible to regulate the climatic conditions in a vehicle while reducing peaks in electrical energy consumption. Thus, the consumption of electrical energy is optimized.
    According to one characteristic, on the predetermined time interval, said at least one operating command is generated so that if during a first period A the value of said at least one parameter indicates that electrical energy is consumed by said at least one parameter an electric transport vehicle, the average power delivered by the at least one actuator during the first period A is less than the value of the average power during the predetermined time interval when only the parameters representative of the climatic conditions are taken into account for generating said at least one operation command.
    Note that in electric transport vehicles equipped with a braking energy recovery device, when the parameter indicates that electrical energy is consumed, the electric transport vehicle is, for example, in a phase traction. Thus, during the first period A, the power delivered by said at least one actuator is decreased relative to the value of the average power during the predetermined time interval when only the parameters representative of the climatic conditions are taken into account.
    According to another characteristic, over the predetermined time interval said at least one operating command is generated so that if during a second period B the value of said at least one parameter indicates that electrical energy is produced by said at least one parameter an electric transport vehicle, the average power delivered by said at least one actuator during said second period B is greater than said value of the average power during said predetermined time interval when only said parameters representative of the climatic conditions are taken into account for said generation of said operation command.
    Note that in electric transport vehicles equipped with a braking energy recovery device, when the parameter indicates that electrical energy is produced, the electric transport vehicle is, for example, in a phase braking. Thus, during the second period B, the power delivered by the at least one actuator is increased relative to the value of the average power during the predetermined time interval when only the parameters representative of the climatic conditions are taken into account.
    According to one characteristic, said at least one operating command applied to said at least one actuator comprises a control signal, during the generation of the operation command, at least one parameter of the control signal being modified as a function of the value of the parameter relating to at least one electric transport vehicle.
    Thus, by modifying at least one parameter of the control signal applied to said at least one actuator, the instantaneous power delivered by the actuator is modified, while keeping the average power value over the predetermined time interval.
    According to one characteristic, the parameter of said control signal is an amplitude or a duration.
    According to one characteristic, the regulation means comprise: a first regulation module configured to generate at least one intermediate operating command as a function of at least one parameter representative of the climatic conditions, and a second regulation module configured to modify said at least one intermediate operating command as a function of the parameter value relating to at least one electric transport vehicle and for generating said at least one operating command applied to said at least one actuator.
    Thus, under equivalent climatic conditions, an operation command of an actuator (intermediate operation control) generated by the first control module can be modified so that the actuator can operate differently depending on the value of the parameter relative to the less an electric transport vehicle.
    It will be noted that the energy consumption is represented by the value of at least one parameter relating to at least one electric transport vehicle, this value being different depending on the mode of movement of the electric transport vehicle. Thus, taking into account the value of said at least one parameter relating to at least one electric transport vehicle, the energy consumption of the mode of displacement is taken into account.
    Furthermore, the second control module can be added to a conventional air conditioning system, that is to say comprising only the first control module, thereby obtaining an air conditioning system with optimized consumption from a classic air conditioning system.
    According to one characteristic, the air conditioning system further comprises energy accumulation means configured to accumulate electrical energy when the value of the parameter relating to at least one electric transport vehicle is indicative of the production of electrical energy. by said at least one electric transport vehicle.
    For example, an electric transport vehicle generates energy when it is in the braking phase.
    For example, when the vehicle is in braking mode, the energy generated is stored in accumulation means and can be reused later.
    According to another characteristic, the air conditioning system further comprises shedding means configured to disconnect said air conditioning system from said power supply network when the value of the parameter relating to at least one electric transport vehicle is indicative of the power consumption. electrical energy by said at least one electric transport vehicle.
    For example, an electric transport vehicle consumes energy when it is in the traction phase.
    Thus, for example, when the vehicle is in traction mode, the energy consumed by this mode being high, the electrical energy consumed by the air conditioning system is zero or reduced and peaks of energy consumption are reduced.
    According to one characteristic, the value of the parameter relating to at least one electric transport vehicle comprises: a value of electrical power, or a traction force, or a braking force, or a distance, or a speed, or an acceleration, or a value representative of a state of opening or closing of the doors of said at least one electric transport vehicle, or a value of a voltage of said electrical network supplying said at least one electric transport vehicle; less an electric transport vehicle.
    According to one characteristic, said at least one parameter relating to at least one electric transport vehicle relates to at least the electric transport vehicle comprising the air conditioning system.
    According to one characteristic, said at least one parameter relating to at least one electric transport vehicle is relative to at least one electric transport vehicle differ from the electric transport vehicle comprising the air conditioning system.
    According to another characteristic, said at least one parameter relating to at least one electric transport vehicle relates to several electric transport vehicles powered by the power supply network.
    Thus, according to different embodiments, the electric transport vehicle comprising the air conditioning system is part or not part of the several electric transport vehicles. The invention aims, according to a second aspect, an electric transport vehicle powered by a power supply network comprising an air conditioning system according to the invention, said control means of the air conditioning system being configured to generate the said at least one operating command applied to said at least one heat or cold generating actuator in addition to the value of at least one parameter relating to at least one electric transport vehicle powered by the power supply network, the value of the parameter indicating that electrical energy is consumed by said at least one electric transport vehicle or that electrical energy is generated by said at least one electric vehicle, said at least one operating command being generated so that the power average delivered by said at least one actuator over the pre time interval determined has substantially the same value as when the regulating means only take into account the parameters representative of the climatic conditions.
    According to one characteristic, the electric transport vehicle further comprises energy storage means configured to accumulate electrical energy, when the value of the parameter relating to said at least one electric transport vehicle is indicative of the production of electrical energy by said at least one electric transport vehicle.

    The electric transport vehicle and the method of regulating parameters representative of the climatic conditions to predefined values in an electric transport vehicle have characteristics and advantages similar to those previously described in connection with the air conditioning system. Other features and advantages of the invention will become apparent in the description below.
    In the accompanying drawings, given as non-limiting examples: FIG. 1 schematically represents an air conditioning system according to a first embodiment of the invention; FIG. 2 illustrates a diagram representing an air conditioning system according to a second embodiment of the invention; - Figure 3 schematically illustrates a control method according to one embodiment of the invention; FIGS. 4 and 5 show time control signals generated by air conditioning systems in accordance with embodiments of the invention.
    Figure 1 shows an air conditioning system according to a first embodiment of the invention. The invention is particularly applicable to urban electric transport vehicles, such as subways or trams, bus trolleys, etc.
    The air conditioning system 1 is mounted in an electric transport vehicle 100. The electric transport vehicle 100 is powered by a power supply network 2.
    The air conditioning system 1 comprises at least one actuator such as a compressor, fans, heating resistors, etc.
    In Figure 1, only an actuator 3 is shown to simplify the figure. In this example shown, the actuator itself is a compressor 3a, the operation of the compressor 3a being controlled by a motor 3b, the motor 3b being powered by a variable frequency inverter 3c.
    Note that the actuator 3 produces heat (for example in air conditioning systems known as "reversible") or cold.
    The air conditioning system 1 further comprises regulating means 6 configured to generate operating commands of the actuators 6c, such as a control controlling the speed of the motor 3b controlling the compressor 3a.
    Of course, the operating commands of the actuators 6c include other controls not shown in the figures, such as commands controlling the speed of the fans, the connection or disconnection of the heating resistors, etc.
    Thus, the operating commands of the actuators 6c are output signals from the regulation means 6.
    The regulation means 6 receive as input a first set of parameters representative of the climatic conditions 6a and a second set of parameters relating to at least one electric transport vehicle 6b. The value of the parameter indicates whether electrical energy is consumed by said at least one electric transport vehicle, or if electrical energy is produced by said at least one electric transport vehicle.
    It will be noted that said at least one parameter relating to at least one electric transport vehicle 6b may relate to the vehicle of the electric transport on which the air conditioning system 1 is mounted, to a second electric transport vehicle powered by the same network of power supply 2, or several electric transport vehicles powered by the same power supply network 2.
    The value of the parameter relating to at least one electric transport vehicle 6b is a function, for example, of actions relating to the driving of the vehicle. An action relating to the driving of a vehicle may be traction or electric braking. Thus, a parameter representative of an action relating to the driving may be a traction force or an electric braking force, its value representing the level of the traction force or the electric braking force respectively.
    Thus, for example, the value of the parameter relating to at least one electric transport vehicle may be: a value of electrical power, or of a traction force, or of a braking force, or of a distance, or a speed, or an acceleration, or - a value representative of a state of opening or closing of the doors of said at least one electric transport vehicle (the opening and closing of the doors being controlled when the vehicle is stationary), or - a value of a voltage of said power supply network 2 supplying said at least one electric transport vehicle.
    Note that when an electric transport vehicle equipped with a braking energy recovery device, powered by a power supply network brakes by means of its traction motors (the action relating to the pipe being a braking action), the voltage on the power supply network increases if the electric transport vehicle is designed such that the electrical energy produced by its motors is returned to the power supply network 2.
    On the contrary, when at least one electric transport vehicle powered by the power supply network 2 exerts a traction force (the action relating to the pipe being a traction), the value of the voltage of the power supply network increases.
    In the embodiment shown, the parameters relating to at least one vehicle 6b comprise a traction force, a braking force, a value representative of a state of opening or closing of the doors, and the measured voltage of the transmission network. 2. The set of parameters representing the climatic conditions 6a comprises in the embodiment shown the temperature inside and outside the vehicle, and the CO2 level. These parameters are conventional parameters in an air conditioning system. Other parameters can be used such as humidity.
    The regulation means 6 are configured to generate the operating commands 6c applied to the actuators as a function of values of the parameters representative of the climatic conditions 6b as well as the value of a parameter relating to at least one electric transport vehicle powered by the network. power supply 2, the value of the parameter indicating that electrical energy is consumed by said at least one electric transport vehicle or that electrical energy is produced by said at least one electric transport vehicle,
    Thus, the operating commands 6c applied to the actuators 3 are generated so that at least one of the parameters representing the climatic conditions is maintained at a predefined value while taking into account the value of at least one parameter relating to at least one electric transport vehicle 6b powered by the power supply network 2.
    As will be described later, said at least one operating command applied to said at least one actuator 3 is generated so that the average power delivered by said at least one actuator 3 over a predetermined time interval has substantially the same value as when the regulating means 6 only take into account said parameters representative of the climatic conditions 6a.
    In the embodiment described in FIG. 1, the air-conditioning system further comprises means for measuring the voltage 7 of the power supply network 2, in order to generate control means 6 at the input, a value of one parameter relating to at least one electric transport vehicle powered by the power supply network 2.
    Figure 2 shows a second embodiment of an air conditioning system for an electric transport vehicle.
    As will be explained, this embodiment is suitable for adapting a conventional air conditioning system to obtain an air conditioning system 1 'according to the invention.
    As for the embodiment shown in Figure 1, a single actuator 8 is shown to simplify the figure.
    In the embodiment shown, the actuator itself is a set of heating resistors 8a, these heating resistors being heat producing actuators. The set of heating resistors 8a is connected to a contactor 8b. The switch 8b makes it possible to connect or not to connect the set of heating resistors 8a to a power supply 8c.
    The contactor 8b is controlled by operating commands 6c.
    Of course, the air conditioning system 1 'comprises other actuators, not shown in the figure.
    In one embodiment, the regulation means 6 'comprise in one embodiment a first regulation module 61' and a second regulation module 62 '.
    The first regulation module 61 'is configured to generate intermediate operating commands 6ci' of the actuators as a function of at least one parameter representative of the climatic conditions 6a '.
    In the embodiment shown, a parameter representative of the climatic conditions 6a 'is the temperature inside the vehicle.
    Thus, the first control module 61 'outputs intermediate operation commands 6ci' actuators as a function of the interior temperature of the vehicle in which the air conditioning system 1 'is mounted.
    The second regulation module 62 'is configured to modify the intermediate operating commands 6ci' applied to the actuators 8 as a function of the value of at least one parameter relating to at least one electric transport vehicle 6b 'and to generate the said at least one an operating command 6c 'applied to said at least one actuator 8.
    In other words, the intermediate operating commands 6ci 'of the actuators 8 are modulated as a function of the value of at least one parameter relating to at least one electric transport vehicle 6b', in order to output operating commands 6c 'applied actuators 8 or 6c 'operating controls applied to the modulated actuators.
    The second regulation module 62 'comprises at the input the intermediate operating commands 6ci' applied to the actuators 8, and the value of at least one parameter relating to at least one electric transport vehicle 6b '.
    In the embodiment shown, the parameters relating to at least one electric transport vehicle 6b 'are an acceleration of the vehicle and a value representative of the state of opening or closing of the doors. The acceleration of the vehicle comes from an accelerometer. Note that the acceleration information from an accelerometer does not know whether the electric transport vehicle brakes or accelerates when the vehicle can move reversibly, that is to say it comprises a driver's cabin at each end.
    Thus, the information complementary to the opening or closing of the doors allows the second control module 62 'to know if the vehicle accelerates or brakes, the vehicle can not accelerate after the closing of the doors.
    In this embodiment, the first regulation module 61 'is configured to generate intermediate operating commands 6ci' applied to the actuators 8 as a function of the interior temperature of the vehicle in which the air conditioning system 1 'is installed, and the second control module 62 'is configured to modify the intermediate operating command 6ci' applied to the actuators 8 as a function of the values of the parameters relating to an electric transport vehicle 6b ', the values being an acceleration of the vehicle in which the air conditioning system 1 is installed and a value representative of a state of opening or closing of the doors of the electric transport vehicle.
    In the embodiment shown, the operating commands applied to the actuators 6c 'control the connection or disconnection of the heating resistors 8a to a power supply 8c by means of a contactor 8b.
    The air conditioning system according to the invention 1, 1 'implements a method for regulating the parameters representative of the climatic conditions to predefined values in an electric transport vehicle.
    A method for controlling the parameters representative of the climatic conditions to predefined values according to an embodiment is shown in FIG. 3. The method comprises the generation E1 of at least one operating command applied to at least one actuator 3, 8 of an air conditioning system according to parameter values representative of the climatic conditions 6a, 6a ', said at least one actuator 3, 8 delivering an average power over a predetermined time interval I.
    The generation E2, E3 of the said at least one operating command applied to the said at least one actuator also takes into account the value of a parameter relating to at least one electric transport vehicle 6b, 6b 'fed by the said power supply network. 2. The value of the parameter indicates that electrical energy is consumed by the at least one electric transport vehicle or that electrical energy is produced by the at least one electric vehicle.
    Said at least one operating command 6c, 6c 'is generated so that the average power delivered by said at least one actuator 3, 8 over said predetermined time interval has substantially the same value PM' as when the control means 6 , 6 'only take into account the parameters representative of the climatic conditions.
    In the mode represented by FIG. 3, the method corresponds to an air conditioning system represented by FIG. 2, that is to say with the regulation means comprising first regulating means 61 'and second regulating means 62 .
    It will thus be noted that the steps E1 and E2 are grouped into one for the embodiment shown in FIG.
    The method shown comprises a step E1 generation of intermediate operating commands 6ci 'actuators according to at least one parameter representative of the climatic conditions 6a'.
    This generation step E1 corresponds to a conventional climatic regulation.
    The method further comprises a step E2 of modifying the intermediate operating commands 6ci 'of the actuators generated in the generating step E1, this modification being implemented as a function of the value of at least one parameter relating to at least one electric transport vehicle 6b 'so that, over a predetermined time interval, the average power delivered PM by at least one actuator 8 has substantially the same value PM' as when the intermediate operating commands 6ci 'are addressed directly to the actuators so to control their operation taking into account only the parameters representative of the climatic conditions 6a '. Operating commands applied to the actuators 6c 'are thus generated at the end of the modification step E2.
    The operating commands of the actuators 6c 'are addressed to the actuators 8 in order to control their operation during a step of controlling the actuators E3.
    Each operating command of an actuator 6c 'comprises a control signal representing a value. The control signal may be for example an electrical signal, such as an analog, digital or logic signal.
    During the modification E2 of said operation command, at least one parameter of said control signal is modified according to said value of said representative parameter of an electric transport vehicle.
    For example, the parameter of the control signal is an amplitude or a duration.
    Figure 3 illustrates graphs showing a control signal. A first graph G1 represents an intermediate control signal or command 6ci 'indicating the power to be delivered by an actuator 8. During the generation step E1 a control signal to be applied to an actuator 8 is generated, the actuator 8 delivering an average power PM 'over a predetermined time interval I.
    A second graph G2 represents the control signal or operating command 6c 'applied to an actuator 8 indicating the power to be delivered by an actuator 8.
    During the modification step E2, the control signal generated during the generation step E1 is modified and generated so that the average power PM over the predetermined time interval I is substantially identical to the value one. average power PM 'of the control signal generated during the generation step E1.
    Figures 4 and 5 show the evolution over time of the operating commands 6c, 6c 'of the actuators 3, 8 generated in air conditioning systems 1,1' according to two different embodiments.
    FIG. 4 represents a first group of signals representing intermediate operating commands 6ci 'of the actuators generated as a function of at least one parameter representative of the climatic conditions 6a, 6a'. Here, the parameter representative of the climatic conditions is the temperature inside a passenger compartment of the electric transport vehicle, and the actuators producing heat comprise heating resistors 8.
    Figure 4 shows two types of operation control of the heating resistors. A first operation command of the heating resistors is represented by a control signal C1 representing a heating power value.
    A second operation command of the heating resistors is represented by a second control signal C2, this control signal being a logic signal, that is to say that as a function of the level or state of this control signal C2, the heating resistors are connected to the supply voltage 2, or they are disconnected from the supply voltage. In the embodiment shown, the control signal C2 is capable of representing only 2 heating power values (full power, zero power).
    A third control signal C3 represents the operation control of the fans. In this example, the signal is a logic signal.
    The control signals have been represented as a function of time t. The driving of the vehicle (not shown) changes with time t, several driving phases are shown. During a driving phase, actions relating to the driving of the vehicle are implemented.
    It will be noted that, depending on the action relating to the driving of the vehicle, the electric transport vehicle consumes or produces electrical energy.
    Thus, there is shown a PHT pulling phase, an on-the-fly phase PHM, a braking phase PHF and a stopping phase PHA.
    In the example shown, these phases form a predetermined time interval I. Of course, in the predetermined time interval I, the number of each of these phases and the order may be different.
    In Figure 4, four actions relating to the driving of the vehicle are shown, a first action being a traction (PHT traction phase), a second action being a walk on the wand (walking phase on the PHM wand), a third action being the braking (PHF braking phase), and a fourth action being the stop (PHA stop phase).
    The parameter values relating to at least one electric transport vehicle are a function of the phase on which the electric transport vehicle is located.
    In the embodiment shown, there is shown a value of a traction force, an electric braking force, and a value representative of a state of opening or closing of the doors.
    Of course, other parameters relating to at least one electric transport vehicle can be taken into account. These parameters may include: - a value of electric power, or of a traction force, or of a braking force, or of a distance, or of a speed, or of an acceleration, or - a value representative of a state of opening or closing of the doors of an electric transport vehicle, or - a value of a voltage of the electrical network supplying at least one electric transport vehicle.
    Thus, as shown in FIG. 4, the value of the force or of the tensile force has a first value ET1 (for example 100% of the maximum value) and a second value ET2 (for example 50%) during the phase the value of these parameters being zero during the other phases represented.
    Similarly, the value of the braking force or force has a first value EF1 (for example 50%) and a second value EF2 (for example 100%) during the braking phase, the value of the effort electric braking being zero during the other driving phases shown.
    The representative value of the opening or closing of the doors being a binary logic signal has a low level when the opening of the doors is not controlled or the doors are closed (being the case during the phases of traction PFIT operating on the PFIM ERA and braking PH F) and a high level H representing the opening of the doors (the opening of the doors being controlled when the vehicle is at a standstill).
    For example, the value of the parameter relating to at least one electric transport vehicle 6b 'indicates that electrical energy is consumed during the PHT or first period A traction phase and indicates that energy is produced during the phase of PHF braking or second phase B.
    During the PHA shutdown or PHM wander phase, energy is neither consumed nor produced.
    FIG. 4 represents a third group comprising operating commands of the actuators 6c '. These commands 6c 'are generated at the modification step E2 of the regulation method. A first operating command C1 is generated by modifying the heating resistor operating command C1 i (intermediate operating control). A second operation command of the heating module C2 is generated by modifying the operating control of the heating module C2i (intermediate operation control). A third operation command of the ventilation module C3 is generated by modifying the operating command of the ventilation module C3i (intermediate operating command).
    The operating commands are represented by control signals C1, C2, C3.
    The value of each control signal C1, C2 represents a power setpoint or power value delivered by the actuator 3, 8. It is such that the value of the average power setpoint PM1, PM2 represented by this signal over an interval predetermined time I is substantially equal to the value of the average power or average power setpoint delivered by the actuator PM1 ', PM2' of the intermediate control signal C1i, C2i generated by the first control module (shown in FIG. 2 ).
    In an air-conditioning system such as that shown in FIG. 1, the regulation means 6 address a speed value 6c (the control signal being a speed) to the inverter 3c. The inverter 3c delivers, as a function of the speed value 6c received, the control power signals of the motor 3b so that it can rotate at the required speed. The motor 3b rotating at the required speed drives the compressor 3a, the compressor 3a thus delivering a given power value.
    Consequently, the value of the control signal 6c is representative of the power setpoint or power value delivered by the actuator 3.
    For example, the values of PM1 and PM1 'are 40% of the maximum value and those of PM2 and PM2' are 60%.
    Of course, these values may have different values.
    In this embodiment, the predetermined time interval I corresponds to the sum of the time intervals associated with each of the driving phases corresponding to a route between two stations. By way of non-limiting example, the PHT traction, PHM travel, PHF braking and PHA stop phases have the same duration of 30s.
    Of course, this duration value may be different and the phase times may be different from each other.
    Thus, during the traction phase PHT, the control signal of the heating module C1 is generated from the first intermediate control signal C1i, of the heating module, this intermediate control signal C1i being modulated by the value of the effort in this example.
    It will be noted that the value of the traction force is a value of a parameter relative to an electric transport vehicle.
    Thus, when the tensile force has its maximum value ET1, the heating resistor control signal C1 or the modulated heating resistor control signal C1 has a value of zero, and when the value of the traction force has the same value. second value ET2, the modulated control signal C1 has a value greater than 0 and less than the value of the average power setpoint PMT over the predetermined time interval I.
    During the walking phase on the wand PHM in which the value of the tensile force is zero, the value represented by the modulated control signal C1 has a value greater than the value of the average power setpoint PMT on the predetermined time interval I. During the braking phase, during which the tractive effort is zero, the value of the modulated control signal C1 has its upper value, this value decreasing when the vehicle is at a standstill, and zero when the door opening command is activated.
    The average value PM1 of the control signal C1 representing the heating operation command is substantially equal to the value of the average power setpoint PMT of the intermediate control signal C1 i of heating generated by the first regulation module 61 'on the predetermined time interval I.
    The second modulated control signal of the heater C2 is changed from the second intermediate control signal C2i of heating so that it has a low level during the pulling phase PHT and part of the stopping phase PHA and the run on the PHM wand and a high level during the PHF braking phase as well as during a walking phase portion on the PHM wand and during the PHA stop phase after closing the doors.
    The value of the average power setpoint PM2 of the control signal C2 representing the heating operation command is substantially equal to the average value PM2 'of the intermediate heating control signal C2i generated by the first control module over the heating interval. predetermined time I.
    Therefore, when the parameters relating to at least one electric transport vehicle 6b 'have a value indicative of the consumption of electrical energy (due for example to the traction of the vehicle), the second regulation module 62' is configured to inhibit at least one of the operating commands 6ci 'of the actuators generated by the first control module 61 or to decrease the value of the signal representing the operation command.
    On the contrary, when the parameters relating to at least one electric transport vehicle have a value indicative of the production of electrical energy (due for example to a braking of the vehicle), the second regulation module 62 'is configured not to modify the operating commands 6ci 'generated by the first control module 61' or to increase the value of the control signal representing the operation command.
    In order to reduce heat losses when the doors of the electric transport vehicle are open, the modulated ventilation control signal C3 has a high level for the entire predetermined time interval I except when the doors are opened.
    Fig. 5 shows control signals according to another embodiment. A first group of signals representing the value of the parameters relating to at least one electric transport vehicle 6b is shown. In this example, the parameters are the acceleration of the vehicle, the speed of the vehicle, as well as a value representative of a state of opening or closing of the doors.
    A second group of control signals 6c, 6c 'comprises an operation command of the compressor or modulated control signal of the compressor, and the operation control of the fan or modulated control signal of the fan.
    A third group of signals comprises a control signal CA, energy storage means, a signal E representing the energy stored in the energy storage means, and a third signal CD representing a control signal of means of shedding.
    The values of the control signals represented change over time t.
    In this embodiment, a first braking phase PHF is shown, followed by a stop phase PHA, a pull phase PHT and a walk phase on the wand PHM.
    As for Figure 4, the order and duration of the phases may be different from those shown.
    The parameter values relating to at least one electric transport vehicle 6b vary according to the driving phase of the vehicle. These values are taken into account when the modulated control signals are generated.
    For example, the value of the parameter relating to at least one electric transport vehicle 6b indicates that electrical energy is consumed during the PHT or first period A traction phase and indicates that energy is produced during the braking phase PHF or second period B.
    Of course, the predetermined time interval I may comprise several first periods A or several second periods B.
    During the PHA shutdown or PHM wander phase, energy is neither consumed nor produced.
    Thus, as shown in FIG. 5, the modulated control signal of the compressor (representing the operation command of the compressor) has a first value during the braking phase, a second value (less than the first value) during the phase and a third value (greater than the first value and lower than the second value) during the pulling phase PHT and the walking phase on the wand PHM. These values are determined so that the value of the average power setpoint or value of the average power PM4 delivered by the compressor during the predetermined time interval I is substantially equal to the average value of a control signal (not shown ) generated taking into account only the parameters representative of the climatic conditions.
    In the example shown in FIG. 5, in order to reduce the heat losses when the doors are open, the modulated control signal of the fan has values decreasing during the braking phase PHF to a minimum ventilation value when the doors are opened during the PHA shutdown phase, and a return to normal ventilation value during the PHT pull and PHM wander phases.
    In one embodiment (FIG. 1), the air conditioning system further comprises energy storage means 11 configured to accumulate electrical energy of the power supply network 2 as a function of the value of the parameter relative to at least one electric transport vehicle or electric transport vehicles powered by the same power supply network 2.
    In other embodiments, the energy storage means and / or the shedding means are located in the electric transport vehicle outside the air conditioning system 1, T.
    The air conditioning system may further include load shedding means 11 configured to disconnect the air conditioning system 1, T from the power supply network 2.
    In this embodiment, the control method comprises the generation of a control signal CA accumulation of the electrical energy of the power supply network 2 as a function of the value of the parameter relating to at least one transport vehicle electric.
    The method may further comprise the generation of a disconnection control of the air conditioning system 1, 1 'of the power supply network 2.
    The AC electrical energy accumulation control signal shown in FIG. 5 presents values that take into account the value of the parameters representative of an action relating to the driving of the vehicle. Thus, during the braking phase PHF, the AC energy accumulation control signal has positive values indicative of the activation of the accumulation of energy even higher than the deceleration is high. Once the full charge is reached or the PHA shutdown phase is reached, the AC power accumulation control signal has a zero value that disables energy accumulation.
    The energy curve E represents an increase in the energy stored in the accumulation means during the braking phase PHF, the energy remaining stable during the stop phase PHA, and decreasing during the phases of traction PHT and walk on the wand PHM.
    The disconnection control signal CD of the air-conditioning system 1, 1 'of the power supply network has a zero level when the vehicle is in a braking phase PHF and in a stopping phase PHA until the closing of the doors . Thus, the air-conditioning system is powered by the power supply network 2. The disconnection control signal CD has a high level when the doors are closed in the stop phase PHA and when the vehicle is in a pulling phase PHT or in a walking phase on the PHM wand. Therefore the air conditioning system is no longer powered by the power supply network 2 but by the accumulation means.
    Note that in one embodiment, a parameter relating to at least one electric transport vehicle relates to at least the electric transport vehicle comprising the air conditioning system.
    In another embodiment, a parameter relating to at least one electric transport vehicle relates to at least one electric transport vehicle differ from the electric transport vehicle comprising the air conditioning system.
    In this embodiment, the parameter relating to at least one electric transport vehicle is relative to several electric transport vehicles powered by the power supply network.
