METHOD FOR CONTROLLING TORQUES WHEN STARTING THE COMBUSTION ENGINE OF A HYBRID VEHICLE TO SWITCH FROM AN ELECTRIC MODE TO A HYBRID MODE

摘要

Method for controlling torques in a hybrid vehicle for starting a combustion engine (2), comprising closing a clutch (8) that couples a gearbox (4) driving a first wheelset (6), this vehicle comprising an electric machine (20) which drives the second wheelset (22), characterized in that in order to couple the combustion engine (2) controlled by a speed regulator it applies, at an instant prior to complete closure of the clutch (8), an instantaneous increase in the torque setpoint on this clutch in order thereafter to switch to regulation of the engine in terms of torque, this offset being calculated in such a way as to compensate for the variations in inertia by taking into consideration the inertia of the electric machine (20) and of the vehicle, and the torque of this machine and the resistant torque of the vehicle. - Figure 1 -
