PROCEDE DE COMMANDE DE COUPLAGE/DECOUPLAGE D'UNE MACHINE DE TRACTION D'UN VEHICULE AUTOMOBILE

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).
