Abstract

A vehicle dynamics control system in a motor vehicle includes an electronic vehicle dynamics control unit which is connected to at least one drive control unit and is configured so as to: determine at least one setpoint slip or a setpoint slip corridor and an actual vehicle speed as a reference speed, and transmit the at least one setpoint slip or the setpoint slip corridor together with the reference speed to the at least one drive control unit. The drive control unit, in accordance with the transmitted values and by way of a function module, determines setpoint rotational speed values at a motor level and carries out a rotational speed control process.
