A method for regulating an active chassis of a motor vehicle as a function of road elevation profile data which lie within a prognosis for a trajectory of the motor vehicle. The prognosis of the trajectory is calculated by a mathematical model at least on the basis of steering angle data of a steering angle sensor of the motor vehicle. The prognosis of the trajectory is assigned to the road elevation profile data detected by at least one environmental sensor. Based on the prognosis, at least one actuator of the active chassis is controlled, and the prognosis of the trajectory is then used exclusively to control the active chassis when the trajectory lies in an area that was classified as navigable based on the environmental data that was detected by at least one environment sensor.

Trajectory-based chassis control

An anti-slip control device for a vehicle having an electromotive drive system includes one or more electric driving motors. In order to limit wheel slip, the rotational speed of the driving wheels is regulated by controlling the rotational speed of the rotary field generated in at least one electric driving motor, each electric driving motor being fed by a controllable converter associated therewith. In order to control the rotational speed, the anti-slip control device constantly informs each converter about the maximum allowed rotational speed of the driving motor or driving wheel associated with the respective converter.

Anti-skid control device for a vehicle having an electromotive drive system

An anti-blocking system for a vehicle having an electromotive vehicle drive unit includes one or more driving motors. During a braking process, the braking effect of the driving motors operating as a generator is limited in such a way that brake slip on at least one driving wheel is limited to a predefined threshold value. The rotational speed of each driving motor is regulated by a controllable converter associated therewith, the ABS control device constantly transmitting, to each converter, a mandatory minimum braking rotational speed for the driving motor associated with the respective converter in order to limit brake slip.

Anti-blocking system for a vehicle with electromotive vehicle drive

In a method for braking of a motor vehicle which is driven by a drive torque of at least one electrical machine electrically connected to an electric energy storage device, the at least one electrical machine is operated in a first operating mode as a generator for generating a generator braking torque. In a second operating mode, the at least one electrical machine is supplied with electrical energy from the energy storage device in such a way that a braking torque opposing the drive torque is generated by the at least one electrical machine.
