METHOD FOR PRODUCING A TORQUE SET FOR ELECTRIC MACHINES OF A VEHICLE MOTOR POWERTRAIN AND VEHICLE MOTOR POWERTRAIN

摘要

Method for generating a torque setpoint for electric machines (ME, HSG) of a powertrain (GMP) of a vehicle, comprising at least one gearbox with controlled claws, a main electric machine (ME) capable of transmitting torque to the wheels of the vehicle on two separate gear ratios, and a secondary electrical machine (HSG) capable of providing a compensation torque to the wheel during the gear changes of the main machine, in which the maximum and minimum torque imposed on the two related electrical machines are calculated on the basis of a forward estimate of a common power supply battery, characterized in that, in anticipation of a change in the ratio of the main machine (ME), a new limitation of the torques of the two machines is imposed in advance. more stringent than that of the ratio established, in order to ensure, without discontinuity during the gear change, the main machine (ME) on the new gear and the torque compensation by the secondary machine (HSG).
