摘要:
In this method for controlling the coupling/decoupling of a traction machine of a motor vehicle to/from at least one wheel assembly, steps are carried out that allow the determination (120) of a moment (t_C1) when a torque set point (Croue_cons) to be applied to at least one wheel assembly of the vehicle is higher (110) than a pre-determined coupling threshold (C1) or higher than a pre-determined decoupling threshold, followed by the calculation (140) of a first parameter (PT1) and/or a second parameter (PS2) depending on said moment (t_C1), and the authorisation (160) of the coupling/decoupling when said first parameter (PT1) is higher (150) than a first pre-determined value (t1) and/or when said second parameter (PS1) is higher (150) than a second pre-determined value (S1).

A device (D) is intended to control a so-called "creeping travel" mode of a vehicle (V) that is capable of moving the latter (V) at a slow speed by providing a variable torque produced by a power train without the driver actuating the brake pedal or an accelerator pedal. This device (D) comprises control means (MC) arranged, when this mode has been activated, to analyse the value of a parameter representative of the current speed of the vehicle (V) consecutive to an actuation of the brake pedal during a first period shorter than a first chosen threshold, and to trigger a deactivation of this mode after a second chosen duration, consecutive to this first duration, when the analysed value remains lower than a second threshold chosen during the second chosen time.
摘要:
The invention relates to a method for controlling the coupling/uncoupling of a drive machine of a motor vehicle to/from at least one set of wheels of the vehicle, comprising steps that make possible the determination (120) of a time (t_C1) when a torque set point (Croue_cons) to be applied to at least one set of wheels of the vehicle is less (110) than a predetermined coupling threshold (C1) or greater than a predetermined uncoupling threshold, followed by the calculation (140) of a first parameter (PT1) and/or a second parameter (PS2) which depend on said time (t_C1), and finally the authorization (160) of the coupling/uncoupling when said first parameter (PT1) is greater (150) than a first predetermined value (t1) and/or when said second parameter (PS1) is greater (150) than a second predetermined value (S1).

A device (D) for adapting a nominal curve for torque transmitted by a clutch (EM) with respect to a position of an actuator of the clutch (EM) is designed to i) define a readjusted nominal position equal to a nominal position minus a reference position from the nominal curve, (ii) determine, for at least one chosen readjusted nominal position, a difference between an observed torque and an estimated and corrected transmissible torque that is a function of a correction coefficient and of an estimated transmissible torque, a function of the value of a conversion coefficient and of first and second nominal extreme curves, and (iii) determine for each chosen readjusted nominal position, in a readjusted nominal curve, a corresponding nominal torque so that it can be adapted according to the corresponding determined torque difference in order to obtain an adapted nominal torque, and to adapt the readjusted nominal evolution curve as a function of each adapted nominal torque in order to obtain an adapted nominal evolution curve.
摘要:
A method for limiting the torque drawn by a first electric machine (12) coupled to a traction combustion engine (2) of a hybrid vehicle, said vehicle comprising a second traction electric machine (20) powered by an electrical energy storage device (16), said first machine, designed to supply current to the onboard network (18) of the vehicle, also being able to charge the energy storage device (16), characterised in that, in case of a high torque request made by the driver and exceeding the capabilities of the combustion engine (2), it limits the torque absorbed by the first machine by adjusting the electrical power delivered for said charging, in order to meet said torque request.
