Process and device for controlling the braking of four-wheel drive vehicles

Process of controlling the braking on a brake bench of a wheeled vehicle having plural interconnected drive shafts, each shaft having a differential, said brake bench comprising for each wheel of the axle a pair of drive rollers;

• said drive rollers being driven in asynchronous fashion by drive means;
• said process comprising:
• --driving one wheel on a shaft in the forward direction and one other wheel on the same shaft in the rearward direction, and
• --adjusting the speed (V.sub.A) of the drive means (7a) of the one wheel (3a) and the speed (V.sub.B) of the drive means (7b) of the other wheel (3b), said two speeds (V.sub.A, V.sub.B) being different 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 said brake bench.
