    101520253035gimagasin, to thereby generate a driving torque. During generator operation, electricity generatestower electric power for charging the energy magazine.
    The method according to the invention is characterized by a hybrid strategy, in which ian operating state for energy conversion, where mechanical energy via the hybrid drivelineconverted to another energy source, the generative operation of the electric motor is controlled dependingon one or fl your parameters, which characterize a heat demand for the interior of the vehiclespace (ie the passenger compartment) and / or one or more of your additional vehicle components(ie vehicle components other than the passenger compartment). The operating license for energythe conversion is particularly useful in the context of the hybrid strategy, ifthe kinetic or potential energy of the vehicle is to be converted into another energyforrn, for example in the context of a braking of the vehicle. The concept of vehicle componentcomponents shall be understood broadly here and below and may include any type of vehicle component.which can be heated during cooking under certain conditions, such asthe mission and possibly also the internal combustion engine itself. The less the electricthe power generated by the electric motor is within the framework of the hybrid strategy, the greater the heataccording to the parameter or parameters, the reduction of the generatedthe risk effect leads to an increase in the internal energy, which is supplied to the interior of the vehicleand / or the additional vehicle component (s). The concept of nuclear energy is thereforeby understanding as an amount of heat generated in a time interval and can thus be interpreted asthermal effect.
    The method according to the invention has the advantage that if there is a highfriend needs, the energy source generated in the operating state for energy conversion is shiftedagainst thermal energy, so that the vehicle's interior space or other vehicle components canheated sufficiently. In addition, the reduction in the generated electrical power leads toa lower charge of the electrical energy magazine, which on the other hand results inthe electric motor is used less to drive the vehicle. In this way the electricity is raisedthe life of the energy magazine.
    In a variant of the method according to the invention, the reinforced one is providedthe generation of heat energy at an increased heat demand only by the actual combustionwhich occurs when the electrical energy magazine is less chargedstrengthened use and thereby produces more waste protection, which can again be released tothe interior of the vehicle or the respective vehicle components.
    In a particularly preferred embodiment, the method according to the invention is setinto a hybrid driveline, which includes a retarder, which in operation converts mechanicallyenergy to thermal energy, which is at least partially supplied to the interior of the vehicle101520253035and / or the additional vehicle component (s). Retardem can be, for examplea hydrodynamic or an electrodynamic retarder. In this case, the operating state becomesenergy conversion the heat energy generated by retardation is so much greater, the greaterThe need for protection is according to the parameters or parameters. In this way, stay within the frameworkfor the hybrid strategy, not only the generated electrical energy is reduced, but also active heatenergy is also generated with a retarder.
    In a preferred variant, it is reduced during operating conditions for energy conversionthe electric power generated by the electric motor with a power value, which is all the greaterthe greater the value requirement according to the parameter or parameters is, whereby that of the retardgenerated thermal energy or the thermal effect is increased by this effect value. In this wayan effective interaction is achieved for the electric motor with the retardem, so that at the same power outputfrom the driveline the heat energy generated by the retarder rises at the expense of the electricthe power generated by the electric motor, when the need for protection is increased.
    In a further embodiment of the method according to the invention, ioperating condition for energy conversion the generative operation of the electric motor directly, ifthe need for friends according to the parameter or parameters reaches a predetermined threshold, ie.the electric motor no longer transmits any electrical power at all. Possibly availablein that case, the possibility, in the event that the protection need according to the parameter orrama rises further after the generative operation of the electric motor has stopped, that ef-the power generated by the internal combustion engine raises a power value, which is again converted byretardem to heat energy. As a result, a particularly high need for protection in the vehicle can beapproved by a load point offset of the internal combustion engine.
    The parameters or parameters that characterize the need for protection may dependin cases of use be differently designed. In a variant of the invention, the parameters dependor the parameters of the external temperature and / or the temperature inside the vehiclespace, whereby the parameters may also give the external temperature respectivelythe temperature in the interior of the vehicle. The greater the need for protection, the lowerthe external temperature and / or the temperature in the interior of the vehicle.
    In a further variant of the invention, the parameter or parameters depend onwhich characterizes the heat demand, at a temperature of a refrigerant, via which it ofThe retarded energy generated is absorbed and at least partially passed on to the vehicleinterior space and / or the additional vehicle component (s). Possibly cancorresponding parameters also give the actual coolant temperature.
    In a further advantageous embodiment of the invention, the parameters are determinedor the parameters which characterize the heat demand, not directly within the101520253035bridging strategy, but provided by one or fl your external vehicle control devices, whichare not designed for the implementation of the hybrid strategy. Possibly the parameters forcharacterization of the need for protection is also determined based on one or more of yourevaluated by the hybrid strategy. For example, such a driver input canconsist of changing the desired temperature in the interior of the vehicle via a userinterface.
    Depending on the case of use, different parameters, which are provided fromvehicle control devices for characterizing the heat demand, be of different designsthe. For example, such a parameter may include an (abstract) measure of heat demandand / or an average utilized protective effect and / or a percentage value. Had toon the need for protection can, for example, be characterized by different numerical values. In particular canthe numerical value 0 characterizes no protection requirement, the numerical value l a low protection requirement, thethe value 2 a central heat demand, the numerical value 3 a high heat demand and the numerical value 4 amaximum protection needs. With such values, the hybrid strategy can then be fed and recuperated.ration is reduced via the electric motor and possibly compensated via a retarder. Abovesaid percentage values may, for example, be so designed that a value of 0% (i.e.no need for protection) stands for maximum recovery and thereby maximum generated electricity.risk effect. On the other hand, the electricity effect decreases with increasing percentage value and increasespossibly fitting a heat element via a retarder, until a maximum heat element ofl00% has been achieved.
    In addition to the method described above, the invention further comprises a devicefor driving a vehicle hybrid driveline, the hybrid driveline comprising a drivelineunit with an internal combustion engine and an electric motor and there the drive torque of the drive unitcan be output to an output. The electric motor then absorbs electrical power from a motor driveelectric energy magazine and generates during a generator operation electric power for chargingthe energy magazine.
    The device according to the invention comprises a control means for controlling the hybridthe driveline based on a hybrid strategy, through which in an operating condition for energyconversion, where the mechanical energy is converted into another form of energy via hybridthe driveline, the electric motor's generator operation is controlled depending on one or fl your parameters, whichcharacterizes a heat demand for the interior of the vehicle and / or one or more of thevehicle components. The electric power generated by the electric motor is the lower, the largerthe need for protection is according to the parameter or parameters, whereby the reduction of theThe electrical power leads to an increase in the internal energy, which is supplied to the vehicleinterior space and / or the additional vehicle component (s).101520253035The method according to the invention is preferably designed so that one or fl arepreferred variants of the method according to the invention can be carried out with devicesningen.
    The invention also relates to a vehicle with a hybrid driveline, which comprisesthe device described above according to the invention.
    An embodiment of the invention is described in detail below by means ofattached Fig. 1. This figure shows a schematic representation of an example of abridge driveline, which can be driven based on the methods of the invention.
    The embodiment of the invention described below is explained with the aid ofthe operation of a parallel hybrid driveline, as shown in Fig. 1. The driveline comprises acombustion engine 1 and an electric motor 2. Between the unit thus formed and aoutput 3 is a transmission 4 connected, which for example is designed as automaticshift transmission. There is also one between the internal combustion engine 1 and the electric motor 2clutch 5 engaged, then if the clutch 5 is opened, the internal combustion engine 1disconnected from the output. Between the electric motor 2 and the transmission 4 is a starting element6 connected in the embodiment shown, which is designed as a transmission externalstarting element. Instead of a transmission external starting element, a transmissioninternal starting elements are used. The driveline according to Fig. 1 further comprises a so-calledretarder 9, which is arranged between the electric motor 2 and the startingThe retarder acts to convert mechanical energy from the driveline if necessaryto thermal energy, which can be supplied via a cooling circuit (not shown) to the vehicle's internal space.me or the passenger compartments of the vehicle. Depending on the embodiment, the retardation may bedesigned as a hydrodynamic retarder or as an electrodynamic retarder.
    The driveline according to Fig. 1 also has an electrical energy magazine 7,which during motor operation supplies the electric motor 2 with energy. There is also the possibilityto drive the electric motor 2 generatively, in which case mechanical energy is taken up fromthe driveline via the electric motor and is used as a charge for the energy magazine 7. The drivelineFig. 1 also has a control device 8 in the form of an HCU (HCU = Hybrid)Control Unit), via which the individual components of the driveline are controlled and regulatedrat on a hybrid strategy.
    The hybrid strategy explained below will always be used, if theenergy must be absorbed from the driveline. It occurs in particular if the kinetics of the vehicleenergy must be reduced or the potential energy of the vehicle must be taken up, for example ifthe vehicle must be braked. In conventional hybrid strategies, one tries to transform itabsorbed mechanical energy to electrical power via the generator operation of the electric motor, which1015202530power is then stored in the energy storage. In doing so, a possible need for protection is not taken into accountfor the interior of the vehicle or possibly also for additional vehicle components. INthe exemplary embodiment described here takes into account a protective need for the interior of the vehiclespace in the hybrid strategy.
    Within the framework of the hybrid strategy described below, the side of the electric motor is controlled7 generator operation and partly the operation of the retarder 9, in order in this way to guarantee an efficientheating of the vehicle's interior space in the event of an existing need for protection. The control device 8 iscorresponds to the heat demand of the vehicle's interior space based on appropriate parametersrar. In a particularly preferred embodiment, a measure of the heat demand is derived basedat the outside temperature and / or the temperature of the passenger compartment. The lower these temperaturestours is the greater the associated heat demand. The need for protection can, for example,pelvis is represented as a percentage value between 0% and 100%. Possibly also availablethe possibility that HCU 8 already has a value for the need for protection over external vehicle controlsdevices that do not belong to HCU or that are requested by HCU. For this, a suitableinterface be provided. For example, an average heat output can be transferred toHCU as the size of the need for protection. External vehicle control devices, which provide the necessarynecessary protection requirements for HCU, may be vehicle control computer, control device for internalspace, air conditioning control for the vehicle's interior space and the like.
    The hybrid strategy in the control device 8 is designed in such a way that an increase in thethe court leads to the electrical power generated via generator operation of the electric motor 2 being reduced.
    At the same time, the hybrid strategy ensures that the retarder 9 generates even more internal energyor thermal effect by absorbing mechanical energy from the driveline, if the heat demandrising. If the protection requirement is represented, for example, by a value between 0% and 100%, one is generatedmaximum electrical power by means of the electric motor and thereby the maximumla recovery, if the heat demand is at 0%. In this case, the retarder is not in operationand generates no heat. Increases the percentage value of the need for protection, adjusted on the one handsince the generator motor's generator operation so that the generated electrical power is reduced. On the otheron the other hand, the retarder is driven, so that it converts the effect into thermal energy, with which it ofthe power generated by the electric motor is reduced. When the percentage value finally reaches 100%, it is canceledthe recovery through the electric motor is complete and instead the corresponding powervalue only to heat energy via the retarder.
    In a preferred variant of the embodiments as above, there are also possiblethe possibility of displacing the load of the internal combustion engine at a protection requirement of more than 100%.point towards a larger power value and to convert the further generated power to101520253035thermal energy via the retard, so that the heating of the vehicle's interior space furthercan be increased.
    With the hybrid strategy just explained, the generation of thermal energy is increased bytarden in case of simultaneous reduction of the recovered electrical power, if there is onehigher protection needs. The heat energy of the retard is then given off via a coolant (not shown).circuit with suitable heat exchangers for the interior of the vehicle. With the hybrid strategyit can thus be achieved that in the case of a higher protection need a larger one is providedamount of heat, without therefore heat energy having to be generated by an additional combustionfuel. In addition, the reduced recovery of electrical power leads to alower charge of the electrical energy reservoir, whereby the hybrid vehicle's share withelectric operation decreases and the service life of the electrical energy magazine increases.
    The embodiments described above are described by means of a hybrid driveline incombination with a retarder. Such powertrains are preferably used in commercial vehicles, such asfor example, city buses. The retarder is used when braking the vehicle. Hybrid-however, the strategy according to the invention can also be used in hybrid drivelines,which has no retarder, insofar as a reduction in the electrical power generated by the electric motor leadsto an increased generation of the thermal effect for the interior space of the vehicle or othersvehicle components. In particular, the hybrid strategy can be so designed that it onlyaffects the power generation of the electric motor, whereby the generated electric power is reduced at highermebehov. As a consequence, in the event of a high need for protection, this leads to a lower charge ofthe electrical energy magazine, which on the other hand leads to an increased operation with combustionthe engine of the vehicle and thereby higher engine waste protection. This motor game-heat can again be supplied via the cooling circuit to the vehicle's interior space by means ofa suitable heat exchanger.
    The embodiment of the invention described above has a number of advantages. INin particular, in the context of the hybrid strategy, a need for protection is taken into accountfor the interior of the vehicle or other vehicle components and based on thisthe generator operation of the electric motor in an appropriate manner. Consequently, a fast and efficientheating of the vehicle is achieved, whereby it is also possible to refrain from additionalprotection, which is propelled by means of fuel from the fuel tank or an additive tank.
    In addition, the proportion of electric driving is reduced in the case of a high heat demand throughthe hybrid strategy, thereby extending the life of the electrical energy magazine, whichused for motor operation of the electric motor.
