Definitions
- Takeoff of a vehicle is understood to be the transition from a stop phase to a vehicle start-up phase.
- the evaluation step includes a step of detecting the vehicle in a traffic jam situation.
- the mapping of the clutch pedal is modified for the first speed and second speed passages.
- the first modification step changes from a first acceleration pedal nominal operation map to a second degraded operation map of said accelerator pedal.
- the second degraded operation map of the accelerator pedal allows for an even depression of the acceleration pedal an effective torque lower than that of the first nominal operation map.
- the first step of modifying the map of the accelerator pedal is performed when the temperature of the clutch is evaluated at a value representative of a heating requiring adaptation of the operation of the vehicle.
- the method may comprise a second step of modifying the map of the vehicle acceleration pedal allowing the passage of the degraded operating mode to the nominal operating mode.
- the invention also relates to a motor vehicle comprising the software and hardware means for implementing the method as described.
- FIG. 1 represents a series of steps of the motor vehicle management method according to a particular embodiment of the invention
- the method advantageously comprises an evaluation step E1 of a protection need against a rise in temperature of a clutch of the vehicle, and a first step, in the takeoff phase of the vehicle, modification E2 of a map of a vehicle acceleration pedal triggered according to the result of the evaluation step.
- Vehicle acceleration pedal mapping means the law giving the engine torque of the vehicle enabling the vehicle to be set in motion as a function of the stroke (ie the depression) of the vehicle. the accelerator pedal. In particular, this law is defined to adjust the torque delivered despite a low depression of the pedal by the driver.
- the first modification step E2 switches from a first acceleration pedal nominal operation map to a second degraded operation map of said accelerator pedal.
- the second degraded operation map of the accelerator pedal allows for a lower acceleration pedal depression an effective torque lower than that of the first nominal operation map.
- the method may advantageously comprise a plurality of cycles, preferably successive cycles, comprising the following steps: a determination E2-1 of a driving time of the vehicle, an E2-2 determination of the presence of an obstacle at the front of the vehicle, particularly at the end of the driving time when the vehicle is stopped,
- step E2 The maximum number of cycles before triggering of the step E2 can be deduced by those skilled in the art when designing the vehicle by simulating traffic jam scenarios and following the evolution of the temperature. In fact, it is considered that, when the number of cycles exceeds the reference value, the clutch has implicitly undergone an increase in its temperature because of frequent takeoffs without possibility of cooling through an increase in the speed of the vehicle. And it is then that the result of the evaluation step is representative of a need for protection triggering the implementation of step E2.
- this step E2-4 for determining the inclination of the vehicle can be integrated in each cycle of the plurality of cycles described above so that the need for protection of the clutch (triggering of step E2) is validated only if, for each cycle, the determined inclination is less than a reference inclination threshold, in particular representative of a slope less than or equal to 5%.
- step E106 After performing steps E104 and E105, then the value of counter N is compared to a corresponding threshold (similar to the reference value described above) in step E106. If N is lower than the threshold (output not of E106) then the method loops back to step Ed, otherwise (yes output of step 106) then the vehicle is placed in a modified pedal mapping operating mode (step E107 ) and the method loops back to step Ed. Going back to step E103, if the delta (t-t1) is greater than REF_1 (output no of step E103) then it is checked (step E108) what is the state of the map of the pedal of acceleration.
- step E108 the delta t-t1 is compared with another time threshold REF_2 (assimilated to the deactivation threshold described above) in a step E1 1 1. If the delta is below this threshold (output not in step E1 1 1) then the modified pedal map is retained (E107) and the method loops back to step Ed.
- REF_2 Similar to the deactivation threshold described above
