Motor car e.g. hybrid or electric car, has electric motor through which torque for braking car is generated to standstill in event of detected malfunction in brake system by automatically shifting brake circuit to regenerative mode

摘要

The car (1) has hydraulic actuatable disk brakes (6) actuatable through a brake circuit (5). The brake circuit is operated over a brake booster (4). The brake booster is more actuatable over driver-operable brake pedals and controlled by using a common control device (10). Retarding torque for braking the car is generated to a standstill through an electric motor (9) i.e. traction motor, in event of detected malfunction in a brake system (2) by automatically shifting the brake circuit to regenerative mode. The electromotor is integrated into a powertrain of the car.
