ABSTRACT:
Process and device for controlling the braking of a brake bench of a wheeled vehicle having plural interconnected drive shafts, each shaft having a differential. One wheel on a shaft is driven in the forward direction and the other wheel on the same shaft is driven in the rearward direction. The speed (V.sub.A) of the drive motor (7a) of the one wheel (3a) and the speed (V.sub.B) of the drive motor (7b) of the other wheel (3b) differ from each other such that the difference of the two speeds (V.sub.A, V.sub.B) is maintained less than a value such as will move another shaft of the vehicle which is external to the brake bench. The difference in the two speeds (V.sub.A, V.sub.B) is maintained less than 5% of the speed (V.sub.A) of the drive motor (7a) in the forward direction (A).
