Abstract
For the control of a brake unit for automotive vehicles, electric signals are generated dependent on the operation of the brake pedal. The signals are processed in an electronic circuit (8) and logically linked to sensor signals containing information on the brake power, the braking effect and/or on the rotational behavior of the individual wheels. Electrically actuatable wheel brakes (1, 2, 3, 4, 32, 33) equipped with an electric drive (M) are controlled by the generated signals. Through a second brake system, brake power is transmitted by the brake pedal (5, 5') either simultaneously or upon overcoming a threshold value to the wheels of one axle, preferably to the front wheels, i.e. front right, front left wheels (VR, VL), the brake power becoming, however, effective exclusively in the event of a fault or a failure of the electrical brake system or of the electric power supply.
