ABSTRACT:
The invention relates to a process for the actuation of an hydrodynamic retarder brake for motor vehicles, which is controlled by an electrohydraulic valve system. The rotational velocity of some part of the drive system (or an average of a plurality thereof) is indicated by a continuously generated electrical signal. When the throttle is released, or the brake pedal, having been depressed is then released, the vehicle velocity at that moment is stored as a reference signal in a memory. If the actual velocity thereafter exceeds the stored value, the hydrodynamic retarder is actuated. The momentary velocity of the vehicle is thereafter continuously compared with the stored reference velocity, and the retarder controlled accordingly. Rapidly applied retarder action is realized by controlling the same using PD control.
