Abstract

A process for the braking of a vehicle on road surfaces with varying frictional values influences the respective braking forces on the wheels of at least one axle via a common braking value. The inventive process recognizes differences between these frictional values, and the common braking value is adjusted so that the wheel located on the surface with the lower frictional value is locked at least intermittently, while the frictional value of the other wheel can be utilized advantageously. The common braking value is reduced at predetermined time intervals, so that the wheel located on the surface with the lower frictional value can start up again from the locked state when an increase in frictional value occurs. Depending on the reaction of the wheel located on the surface with the lower frictional value, it is then possible to decide whether further locking of this wheel is acceptable, or must be terminated because of anticipated damage to the tire, or reduction of travel stability.
