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

摘要

A method for producing a torque setpoint for electric machines (ME, HSG) of a powertrain (GMP) of a vehicle, comprising at least one controlled jaw gearbox, a main electric machine (ME) capable of transmitting torque to the vehicle wheels on two separate gear ratios, and a secondary electric machine (HSG) capable of providing compensation torque to the wheel during gear changes of the main machine, in which the maximum and minimum torque imposed on both machines electrical ratios are calculated based on a forward state 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 couples of the two electric machines more strict than that of the established ratio, in order to ensure without interruption during the gear change, the synchronism the main machine (ME) on the new gear and the torque compensation by the secondary machine (HSG).
