Abstract

A hydraulic system of a vehicle includes a hydraulic pump with variable delivery capacity. The hydraulic pump is controllable as a function of a load and operatively connected to a drive of the vehicle. The system includes a first brake system for reducing a speed of the vehicle by at least one friction brake, and a permanent brake system being independent of the first brake system and configured to reduce the speed of the vehicle. The permanent brake system includes a first retarder circuit which cooperates with the hydraulic pump such that kinetic energy is removed from the vehicle by the permanent brake system via the hydraulic pump in order to decelerate the vehicle.
