SYSTEME DE CONTROLE D'UN COUPLE DE TRACTION ET/OU DE FREINAGE SUR AU MOINS UNE ROUE D'UN VEHICULE TERRESTRE A MOTEUR ELECTRIQUE

摘要

The system has a measurement module (23D) measuring a sliding value of a drive wheel (1) at an instant given in response to indication of speed (Vr) of the wheel at the instant and speed (Vv) of a vehicle relative to the ground. A control module (23A) controls current of an electric traction machine (2) e.g. self-drive three-phase synchronous motor, to adjust torque applied to the wheel relative to the value such that the wheel sliding respects setpoint relation. The relation corresponds to maintenance of a minimum ground adherence level to the wheel in a running condition.
