  • Method for traction control in a motor vehicle, and control system for carrying out the method
    Patent number: 8996221
    Abstract: A motor vehicle has a drive unit with at least one electric machine (14, 15) and a control system for traction control. The control system has an ESP control unit (18) that determines a setpoint slip in a manner dependent on the driving situation for each driven axle (10, 11) or each driven wheel (12, 13), and controls the drive unit in a manner dependent on the setpoint slip. The ESP control unit (18) determines a motor setpoint rotational speed for the respective electric machine (14, 15) in a manner dependent on the setpoint slip. An electronic power system (21, 22) of the respective electric machine (14, 15) controls operation of the respective electric machine (14, 15) based on the respective motor setpoint rotational speed.
