    [0004] The invention also relates to a motor vehicle comprising such a management system of a change of driving mode. Other advantages and features of the invention will appear better on reading the description of a preferred embodiment which follows, with reference to the figures, given by way of non-limiting example: FIG. 1 is a schematic representation of a management system of a change of driving mode according to the embodiment of the invention; FIG. 2 is a flow diagram relating to a method of managing a change of driving mode of a motor vehicle according to the embodiment of the invention; FIGS. 3A and 3B are illustrations relating to the variations of a steering wheel torque and a steering angle of the vehicle considered independently in the context of the implementation of a process validation step managing a change of driving mode according to the embodiment of the invention; FIGS. 4A and 4B are illustrations relating to the variations of the steering wheel torque and the steering angle of the vehicle considered together in the context of the implementation of the validation step of the method of 3035054 7 management of a change of driving mode according to the embodiment of the invention, and - Figure 5 is a schematic representation of the operation of the management method of a change of driving mode according to the embodiment of the invention. the invention.

This processing unit 2 is able to carry out instructions for the implementation of FIG. a computer program. This selection device 2 is able to transmit, for example to a driver of the vehicle, different driving modes that can be selected from the input elements 6. These modes of driving are non-exhaustive and not limiting in number to five and correspond for example to: - a mode called "sport" which amplifies the pleasure of driving; - a mode called "comfort" that fades the road and calms the driving; 15 - a so-called "neutral" mode that is balanced between sport and comfort; - a so-called "economic" or "eco" mode that will stage the economic spirit of the vehicle (oriented towards reducing fuel consumption), and / or the ecological spirit of the vehicle (oriented towards well-being and reduction of fuel consumption); the carbon footprint), and 20 - a so-called "personalized" mode that allows to configure a mode that can take all or some of the characteristics of the driving modes mentioned above. The selection device 2 is connected via its communication interface 25 to the on-board network 5, which can be multiplexed and preferably corresponds to a network known under the name "CAN" bus (Area Network Control). The CAN, declined in different standards (ISO 11898-2, IS011898-3, SAE J2411) depending on the speed or the number of lines of communications used is the communication protocol by far the 30 most used today among the global manufacturers of vehicles. But the invention could be generalized to other embedded networks 3035054 9 (VAN, LIN, Flexray, AFDX ...), and all digital network communication systems fitted to these vehicles. In the present embodiment, the system 1 comprises at least one dynamic control device 3 of the vehicle with which the selection device 2 is connected via the on-board network. The dynamic control device 3 of the vehicle is able to act on the movement / movement of the vehicle and the kinetic feeling by the driver driving the vehicle. The system 1 preferably comprises a plurality of dynamic control devices 3 which cooperate with the selection device 2. Each dynamic control device 3 comprises a control unit 15 and a functional unit 14. The control unit 15 is able to control the functional unit 14 which acts directly on the behavior of the vehicle. This dynamic control device 3 of the vehicle corresponds in a non-exhaustive and non-limiting manner to: a front steering management system; - a rear steering system; A braking management system; - a shock absorber management system for controlling the suspension of the vehicle; - a vehicle engine management system; - A gearbox management system, and / or 25 - a management system assistance / assistance to driving including able to ensure a steering of the motor vehicle fully or partially autonomous. As we have seen, the system 1 also comprises at least one vehicle driving control device 4 which is connected to the selection device 2 via the network 5. The system 1 comprises preferably, a plurality of room control devices 4 which cooperate with the selection device 2. Each room control device 4 comprises a control unit 19 and a functional unit 20. The control unit 19 is able to control the functional unit 20 which acts directly on the driving environment of the vehicle including the sound, visual, tactile or even olfactory. This ambience control device 4 corresponds in a non-exhaustive and nonlimiting manner to: a system for managing the ambient lighting of the passenger compartment of the vehicle; a sound management system in the cabin, for example by reproducing sounds relating to the engine to reinforce the sound of the latter and / or sounds relating to the operation of the vehicle such as sounds related to alerts and / or sound indications, and / or ambient sounds associated with a sound design; a system for managing the lighting of the visual interfaces and / or the vehicle equipment control interfaces which is capable of varying, for example, the light intensity or the colorimetry of the light sources included in the visual interfaces such as information indicators present at the dashboard such as speed and / or engine speed counters, and in control interfaces such as control buttons and / or creating light forms enhancing the sensory character of a current mode. ; a system for managing the information content of the visual interfaces of the vehicle suitable, for example, for adapting the informative content of the meters or the multimedia systems according to the selected driving mode; - an equipment management system that affects the environmentally and economically efficient operation of the vehicle, such as heating and air-conditioning systems; 5 - a module management system including a comfort function and which are arranged in the vehicle, for example a massage module included in a vehicle seat. The control unit 15, 19 of each dynamic vehicle control device 3 of the vehicle and of each ambience device 4 comprises hardware and / or software elements, more precisely at least one processor 16, 21 cooperating with elements of FIG. memory 17, 22. The control unit 15, 19 is able to execute instructions for the implementation of the computer program. For each dynamic control device 3 of the vehicle and each ambience device 4, it is understood that the functional unit 14, 20 is a component of these respective control devices 3, 4 which is driven by the control unit. respective command 15, 19. By way of example, when the dynamic control device 3 of the vehicle corresponds to the engine management system, this functional unit 14 corresponds to the engine. It will be noted that the memory elements 17, 22 of the vehicle dynamics control and ambience control devices 4 record driving mode changing criteria 18, 23 including: - configuration parameters of the functional unit 14, 20, and data relating to a duration T relative to an instant called "initiation" of the change in driving mode from which the configuration parameters must be applied to the functional unit 14, 20 .
    [0006] The criteria 18 of each vehicle dynamics control device 3 additionally include data relating to conditions of stability and comfort of the vehicle. These conditions include threshold values for variation of the steering wheel torque, steering wheel angle variation 5, variations of the steering wheel angle speed, as well as a threshold sum value of the cumulative effects, corresponding to the sum of these threshold values of variation of the mentioned parameters.
    [0007] It should be noted that in this system 1, each vehicle dynamic control device 3 operates independently from the other dynamic control devices 3 fitted to the vehicle and also with respect to the ambient control devices 4. It is the same with each room control device 4 driving the vehicle. The system 1 is able to implement a method for managing a change of driving mode illustrated in FIG. 2. This method comprises an initial parametering step 21 of the selection device 2 during which it is able to detect the dynamic control devices 3 and / or the ambient control devices 4 fitted to the vehicle. This selection device 2 is also able to detect newly added control devices 3, 4 in the vehicle or newly activated. The control devices 3, 4 thus detected are then configured in the selection device 2 to be used in the context of the operation of the different driving modes of the vehicle. The configuration of the control devices 3, 4 in the selection device 2 is stored in the form of the data 13 in the memory elements 12 of the processing unit 9 of this selection device 2. Such a parameterization step 21 is preferably performed 3035054 13 during the manufacture of the vehicle in the factory and / or from a car dealer. The method for managing a change of driving mode comprises a selection step 22 in which one of the driving modes that are broadcast by the selection device 2 is selected from the input elements 6 of this selection device. 2. It should be noted that these different driving modes can be broadcast via the display interface 7 and / or the sound interface 8 of the selection device 2.
    [0008] The method then comprises a processing step 23 for identifying the dynamics control 3 and the driving environment 4 controls of the vehicle which are likely to be used for the implementation of the selected driving mode. More precisely, the processing unit 9 of the selection device 2 realizes an identification of the control devices 3, 4 concerned from the data 13 archived in the memory elements 12 of this selection device 2. These data 13 include, for example, each driving mode that can be implemented in the vehicle, the dynamic control devices 3 and the vehicle control environment 4 that have been detected and configured in the selection device 2 during the step 21. Once these control devices for the dynamics 3 and the driving environment 4 of the vehicle have been identified, the processing unit 9 then generates a request for the change of driving mode. During a transmission step 24, the processing unit 9 of the selection device 2 sends via its communication interface 10 and the on-board network 5, the change of driving mode request to each dynamic control device. 3 and room control 4 identified during the processing step 23 and in particular to the control unit 15, 19 of each of these control devices 3, 4. During a reception stage 25 of this request by the control unit 15, 19 of each of the room control devices 4 and control 5 of the dynamic 3, a processing of said request is made by the control unit 15, 19 to identify the selected driving mode. Subsequently, the method comprises a selection step 26 performed by the control unit 15, 19 of each of the environment control devices 4 and control of the dynamic 3, during which the change criteria 18, 23 of driving mode are selected in the memory elements 17, 22 of the control unit 15, 19 of each of the control devices 3, 4 in order to implement the driving mode identified during the reception step 25 As we have already stated, these criteria 18 include configuration parameters of the functional unit 14, 20 of each of the control devices 3, 4 and also include a duration T which makes it possible to determine starting from a moment of reception of the request, the initiation time when the change in driving mode must be initiated by the control devices 3, 4. With regard to the criteria 18 of each control device of the dynamic 3 of the v vehicle, they also include the data relating to the stability conditions of the vehicle. The method then comprises a step of validating the conditions for carrying out the change of driving mode by each vehicle dynamic control device 3. This validation step 27 makes it possible to verify that: the conditions for carrying out the change of driving mode are in good compliance with the operating safety conditions of the device for controlling the dynamic of the vehicle; and the effect on the stability conditions of the vehicle resulting from the implementation of the change in driving mode by the vehicle dynamics control device 3 is low or even zero. This verification step 27 is performed before a step of initiating the change of driving mode by the vehicle dynamics control devices 3, that is to say before implementing the change of driving mode. by these dynamic control devices 3.
    [0009] Specifically, this validation step 27 includes a substep of checking the ability of each vehicle dynamics control device 3 to be able to contribute to the achievement of the change of driving mode according to the state of the vehicle. 3. In other words, a device 15 for controlling the dynamics 3 of the vehicle independently determines the other control devices 3, 4 and according to its own safety constraints, if it is suitable. to operate the change of driving mode.
    [0010] More specifically, the control unit 15 of this dynamic control device 3 performs at least one measurement of the operating parameters of the functional unit 14 in order to determine the operating state of this dynamic control device. 3. During this control sub-step 28, the control unit 15 performs a particular treatment of the previously measured operating parameters as well as configuration parameters relating to the selected driving mode from the criteria 18, in order to estimate to what extent the change of driving mode can be achieved with particular regard to the safety constraints of the control device 30 3.
    [0011] If the control unit 15 determines that the dynamic control device 3 is not able to carry out the driving mode change, then the determination sub-step 28 is performed again until that this dynamic control device 3 of the vehicle is capable of effecting the change of driving mode with particular regard to its safety constraints. On the other hand, if the processing unit 15 determines that the dynamic control device 3 of the vehicle is able to carry out the driving mode change, then the validation step 27 provides for a verification sub-step 29 that conditions of stability of the vehicle allow the implementation of the change of driving mode by the dynamic control device 3 of the vehicle. This verification sub-step 29 contributes to securing the change in driving mode operated by the vehicle dynamics control device 3 with regard to the effect that this change may have on the stability conditions of the vehicle. More specifically, this verification sub-step 29 makes it possible to check that the contribution of this effect of the dynamic control device 3 to the effects resulting from the other dynamic control devices 3 involved in the change of driving mode, n has only a limited impact on vehicle stability conditions. These conditions of stability of the vehicle are defined in particular by the variation of a torque Va of the steering wheel and the variation of a steering angle Vb of the steering wheel, and these conditions have a direct impact on the behavior of the vehicle. In the context of the implementation of this verification sub-step 29, the variations of the steering wheel torque V and the steering wheel steering angle Vb can be considered independently with reference to FIGS. 3A and 3B, or in combination, considering their cumulative effects, with reference to Figures 4A and 4B.
    [0012] During this verification sub-step 29, the control unit 15 of the dynamic control device 3 is able to determine on the basis of the measurement of the operating parameters of the dynamic control device 3 and the parameters. of configuration relating to the selected driving mode: a torque variation value Va of the steering wheel, a steering angle variation value Vb of the steering wheel and a value of sum S resulting from the sum of the effects of these two. values of variation of torque Va and angle Vb. It will be understood that the sum value S and the values of torque variation Va and angle Vb are estimates that are likely to result from the implementation of the change of driving mode by the dynamic control device 3. of the vehicle.
    [0013] Thus, during this verification sub-step 29 if: the flying torque variation value Va and the steering angle value Vb of the steering wheel are substantially lower than the threshold value of variation of the steering wheel torque and the value respectively. steering wheel angle variation threshold, and / or ^ the sum value S of the effects of the deviating torque value Va flying with the steering angle variation value Vb of the steering wheel is substantially less than the the threshold value of variation of the steering wheel torque and the threshold value of steering wheel angle variation, then the dynamic control device 3 of the vehicle is able to implement the change of driving mode and more precisely the selected driving mode.
    [0014] Conversely, if the stability conditions of the vehicle are not verified, then the control and check substeps 29 are then reiterated. These two substeps 28, 29 are then renewed until their conditions are satisfied, which then induces that the change of driving mode by the vehicle dynamics control device 3 is carried out subsequently and without prejudice. 5 on the change of driving mode of the other control devices of the dynamics and the driving environment 3, 4 involved in the context of this change of driving mode. It should be noted that the check and check substeps 28 may be performed in a different order. Indeed, the verification step 29 can be performed before the control step 28. The threshold values of variation of the steering wheel torque and flying angle variation are maximum values beyond which the behavior of the vehicle is considered. as irrelevant from a delivery point of view (felt to be unpleasant for the user) while remaining away from the vehicle's limit conditions of instability. Such a situation results from the combined effects on the behavior of the vehicle which come from the voluntary or inadvertent change of the driving mode emanating from the selection device 2, and which is implemented by the various devices for controlling the dynamics 3 of the vehicle. This behavior of the vehicle is then likely to disturb the driver when changing the driving mode and / or to place it in a situation that can be perceived as anxiety, or at least 25 suggesting that a technical problem occurs. In addition, it will be noted that the validation step 27 also makes it possible to prevent untimely requests generated by the selection device 2 which are related to changes in driving mode from causing a sudden and unexpected change in the behavior of the driver. vehicle that is dangerous and disruptive to the driver. Subsequently, the method provides for a step of initiating the change in driving mode by each vehicle dynamics control device 3 and by each atmosphere control device 4 and this, by the implementation of criteria 18, 23 of change of driving mode. More precisely, the control unit 15, 22 of each control device 3, 4 ensures the control of the functional unit 14, 20 by applying to it the configuration parameters coming from the criteria 18, 23. This initiation step 30 is performed at the initiation time determined according to the duration T which starts from the moment of reception of the request received by each control device 3, 4 relating to the change of driving mode. As we have seen previously, the initiation of the dynamic control devices 3 can take place after this initiation time which is predefined, since these control devices 3 are not able to implement the change of driving mode at the expiry of this moment zo of initiation. As mentioned above, each vehicle dynamic control device 3 as well as each ambient control device 4 of the vehicle comprises the criteria 18, 23 for changing the driving mode that are specific to each of the vehicles. these control devices 3, 4 and function of the selected driving mode. These criteria include the configuration parameters of the functional unit 14, 20 and the duration data T defining the initiation time of the driving mode change where the configuration parameters are to be applied to the control unit. functional unit 14, 20. In an example of a change of driving mode described in FIG. 5, at the moment of reception t0, the vehicle dynamics and vehicle atmosphere control devices 3 receive of the selection device 2 a request for changing the driving mode, which time can be assimilated to that in which the driver 5 changes the mode at the selection device 2. It is considered that the driving mode selected at the level of the selection device 2 is the sport mode. In this example, the control devices 3, 4 involved in implementing the change of driving mode in favor of this sport mode correspond to those which are likely to create sporting feelings by the driver. These control devices 3, 4 are in a nonlimiting and non-exhaustive manner: for the room control devices 4 driving: the sound management system 31 in the passenger compartment, the lighting management system 32 visual interfaces and / or vehicle equipment control interfaces and the information content management system 33 of the visual interfaces of the vehicle. for the vehicle dynamics control devices 3: the front steering management system 37, the rear steering management system 38, the engine management system 34 of the vehicle, the management system of the steering box, speed 35, and the shock absorber management system 36. At the initiation time t1 for changing the atmosphere, the sound management systems 31 in the passenger compartment, lighting management 32 of the visual interfaces and / or vehicle equipment control and information content management interfaces 33 of the visual interfaces of the vehicle implement the change in sport mode. Specifically, sound management system speakers 31 30 emit a reinforced sound that is adapted to the sounds of the engine, the colorimetry and the intensity of the light sources included in 3035054 21 counters of the dashboard of the vehicle are modified and the information on the operation of the vehicle displayed in these counters are adapted to deliver an informative content more related to this sport mode by displaying, for example, data on the engine performance. At initiation time t2, the engine management systems 34 and the management of the gearbox 35 in turn make the change of mode by switching to sport mode. Under these conditions, the engine and the gearbox are then configured so that the driver has the maximum acceleration potential of his vehicle when he needs it, for example by gradually increasing the engine torque and the configuration of the engine. shift from gear to higher engine speeds.
    [0015] Then at initiation time t3, the shock absorber management system 36 operates in sport mode with damping laws of the vehicle which are then modified from the steering suspensions of the vehicle so as to make them firmer.
    [0016] Subsequently, the front-steering management systems 37 and the rear-steering steering systems 38 carry out, respectively, at the initiation times t4 and t5, the change of driving mode by switching to sport mode by improving the agility, the firmness , directional accuracy and the adaptation of the turning radius of the forward and reverse directions therebetween. In this example, the vehicle driving environment control devices 4 change their driving mode almost instantaneously as soon as they receive from the selection device 2 the driving mode change request. In other words, the moment of initiation t1 of the change of driving mode by the vehicle control device 4 of the vehicle control succeeds substantially instantaneously at the moment of reception tO of the request for change of mode driving. This initiation time t1 is between about 0.1 and 0.3 s, and is preferably 0.2 s. As regards the other instants of initiation t2 to t5, they are for example: for initiation moment t2 between about 0.1 and 0.2 s, and is preferably 0.2 s; At the moment of initiation t3 of between approximately 0.5 and 1 s, and is preferably 1 s; at the moment of initiation t4 of between approximately 0.5 and 1 s, and is preferably 1 s, and for the initiation moment t5 between approximately 1 and 10 s, and is preferably 2s. It will further be noted that the initiation of the change of driving mode by several devices for controlling the dynamics of the vehicle 3 is performed sequentially. And, the initiation of the change of driving mode by several control devices 4 of the vehicle driving environment is carried out simultaneously. As we have stated above, the initiation instants t1 to t5 of the control devices 3, 4 are determined from the duration T 25 defined in the criteria 18, 23 included in the memory elements 22, 17 of FIG. each control unit 15, 19 of the dynamic control devices 3 of the vehicle and of the driving environment 4. However, insofar as the control unit 15 determines during the verification step 27 of the method that the vehicle dynamics control device 30 is not able to achieve the change of driving mode, the latter then implements the change of mode 3035054 23 conducted at a subsequent initiation time which may be different from the initiation time t2, t3, t4 or t5 defined in the criteria 18. But this change of mode The late driving is performed smoothly by virtue of the implementation of the validation step 27. Moreover, a vehicle dynamics and ambience control device 4 implements the change. subsequent driving mode has no effect on the implementation of this change by the other control devices 3, 4.
    [0017] Thus, the method then provides for a change of driving mode which is progressively achieved by the control devices of the vehicle dynamics 3 and the driving environment 4 so that the driver is not an unpleasant feeling resulting the combined effects of the change of driving mode implemented by these 15 control devices 3, 4. In addition, one of the particularities of the invention lies in the fact that each dynamic control device 3 is able to implement autonomously / independently the steps of selecting 26, validating 27 and initiating the change in driving mode of this method. In the same way, each room control device 4 is able to implement autonomously / independently the selection steps 26 and initiation 30 of the change of driving mode of the vehicle.
    [0018] The invention also relates to the computer program which comprises program code instructions for executing the steps of the method of managing the change of driving mode. In this embodiment, this program is executed by the processing unit 9 of the selection device 2 and by the control units 15, 19 of the vehicle dynamics and ambience control devices 4 of 3035054. conduct. The present invention is not limited to the embodiment which has been explicitly described, but includes the various variants and generalizations thereof within the scope of the following claims.
