Process and circuit arrangement for the reduction of disadvantageous effects of engine stall torques
First Claim
1. A process for the reduction of disadvantageous effects of engine stall torques on the braking behavior of a vehicle which is equipped with a brake unit furnished with an anti-lock control system, wherein, independently of any actuation of the brake, the brake slip of the driven wheels is monitored and, in the event of a rotational behavior of the driven wheels being typical of the effect of engine stall torques, a pressure build-up in the wheel brakes of the driven wheels is prevented or existing brake pressure is reduced.

Abstract
For the reduction of disadvantageous effects of engine stall torques on the braking behavior of a vehicle which is equipped with a brake unit having an anti-lock control system, the brake slip of the driven wheels is monitored independently of any actuation of the brake. In the event of a rotational behavior of the driven wheels which is typical of the effect of engine stall torques, in particular in the event of a brake slip at the driven wheels exceeding a limit value, brake pressure existing in the wheel brakes of the driven wheels is maintained constant or reduced, or, if the braking action has not yet commenced, the supply of brake pressure into the wheel brakes of the driven wheels is prevented.

6. Apparatus for reducing the effects of engine stall torques on the braking behavior of driven wheels of a vehicle also having non-driven wheels, said apparatus comprising:
-
first means for developing brake slip signals representative of brake slip of the driven wheels of the vehicle; second means responsive to said brake slip signals for; (a) monitoring said brake slip signals independent of brake actuation, and (b) developing a control signal when said brake slip signals exceed a pre-established level; and third means responsive to said control signal for preventing application of brake pressure to wheel brakes associated with the driven wheels of the vehicle until the brake slips of the driven wheels of the vehicle are substantially zero. - View Dependent Claims (7, 8, 9, 10)

11. A process for reducing the effects of engine stall torques on the braking behavior of driven wheels of a vehicle also having non-driven wheels, said method comprising the steps of:
-
determining the brake slip of the driven wheels of the vehicle; monitoring the brake slip of the driven wheels of the vehicle independent of brake actuation; determining when the brake slip of the driven wheels of the vehicle exceeds a pre-established level; and preventing application of brake pressure to wheel brakes associated with the driven wheels of the vehicle until the brake slips of the driven wheels of the vehicle are substantially zero. - View Dependent Claims (12, 13, 14)
