Brake system having two brake circuits, with electronical load dependent braking force distribution, for motor vehicles having an ABS system, comprising a device for failure recognition in a front axle brake circuit

摘要

The system briefly increases the braking pressure at least one rear wheel during a control phase of a load distribution device for decelerations less than a certain value, determining the wheel behavior using the resulting wheel speed (s) and detecting failure of the front axle braking circuit if rear wheel slip increases. The control phase is then interrupted and pulsed full rear wheel braking pressure applied.
