Abstract
A method of electronic brake force distribution is applied to contribute to vehicle stability even in the event of failure of the system that detects failure of the front-axle brake circuit (,) in a vehicle (,). The method involves initiating a pressure maintenance or pressure reduction phase only after the standards with respect to a minimum vehicle deceleration upon brake circuit failure are met. This way, it is ensured that the standards are observed, on the one hand, and locking of the rear wheels (,) before the front wheels (,) is prevented with great likelihood, on the other hand. Thus, electronic brake force distribution (EBD) is switched over to less sensitive criteria. This makes allowance for both possibilities in the event of a failure of a pressure switch (,), i.e., that the front-axle brake circuit (,) is intact or that it is defective.
