Abstract:
Brake system for a motor vehicle, with at least one control unit, which includes at least an antilock controller and a defect detection unit, the defect detection unit recognizing both defects within the control unit and also defects in the components and connections outside the control unit, and in its voltage supply, characterized in that the defect detection unit, as a function of the defective conditions which it has recognized, initiates a complete deactivation of the antilock controller, allows it to remain active with limited functionality, or allows it to remain active with complete functionality, complete deactivation occurring only in the case of defects which can lead to a critical deterioration in the reliability of the braking action, of the braking stability, and/or of the steerability, such defects including those within the control unit, in actuators which adjust the braking force, and/or in the voltage supply, whereas, in the case of individual defects which do not lead to a critical deterioration in the reliability of the braking action, of the braking stability, and/or of the steerability, the antilock controller remains active at least to a limited extent.
