Torque e.g. electric traction torque, controlling system for e.g. car, has control module controlling rotating machine current to adjust torque applied to wheel relative to sliding value such that sliding of wheel respects setpoint relation
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.
