Abstract
A braking system for a motor vehicle includes a brake device, an electric machine, a service brake system and a system controller. The electric machine has a rotor arranged to be torque-transmitting coupled to the brake device and to a vehicle wheel. The service brake system is arranged for selectively braking the vehicle wheel. The system controller has a memory with a plurality of stored operating modes, and a processor arranged for commanding a braking torque from the brake device, the electric machine operating in a generator mode, or the service brake system depending on a driving operating state of the motor vehicle.
Claims19
A braking system for a motor vehicle which can be driven by an electric machine, wherein the electric machine has a rotor, which can be torque-transmittingly coupled to a brake device and to at least one vehicle wheel, wherein the braking system also has a service brake system for wheel-selective braking torque application to at least the vehicle wheels on a first vehicle axle,
- wherein:
- the braking system comprises a system controller in which a plurality of operating modes of the braking system are stored, which carry out a different distribution of braking torques between the brake device, the electric machine in generator mode and the service brake system according to a current driving operating state of the motor vehicle.
