PCT No. PCT/EP96/04529 Sec. 371 Date Nov. 12, 1997 Sec. 102(e) Date Nov. 12, 1998 PCT Filed Oct. 18, 1996 PCT Pub. No. WO97/23371 PCT Pub. Date Jul. 3, 1997A method of monitoring a brake system which is equipped with anti-lock control (ABS) and a system for electronic control of brake force distribution (EBV). The system includes two brake circuits in a black/white brake circuit split-up, the EBV function or control is principally released only when the vehicle deceleration exceeds a predetermined limit value (GWN). To identify a front-axle brake circuit failure, acceleration criteria, i.e., criteria responsive to the acceleration behavior of the vehicle wheels, are predetermined and monitored. Further, slip range monitoring in conjunction with acceleration range monitoring is performed. Upon 'detection' of an acceleration criterion or when a limit value (GW2) predetermined as an acceleration criterion is exceeded, and/or upon 'detection' of values which are outside the slip range (GW1) or the acceleration range (GW5), a 'suspected' front-axle brake circuit failure is signaled, and intervention into the electronic control of the brake force distribution (EBV) is performed.
