Vehicle drive train controlling method, involves dividing intermediate control signals in drive control torque signals of electric machines by decoupling unit, and controlling engine speed in brake mode, using signals

摘要

The method involves determining a load level of a drive of an infinitely variable transmission, and a speed of a thermal engine, by a determination unit (36). Intermediate control signals (V1, V2) are obtained by adjusting the determined values. The signals in the drive control torque signals of electric machines, are separated by a decoupling unit (35). The speed is controlled in a brake mode, using the torque signals. An independent claim is also included for a device to control a drive train with an infinitely variable transmission in retro mode for implementing a method of controlling the drive train.
