Abstract
A braking system includes a service braking system having friction brakes actuatable by a pressure medium, an endurance braking system realized as a hydrodynamic or electrodynamic retarder, an electric machine connected to the wheels on an axle and operatable as a generator, and a foot-brake valve actuatable via a brake pedal. The braking-force demand signaled via a displacement of the pedal is satisfied, in order of priority, by the electric machine in generator operating mode, the retarder, and the service braking system. The distribution of the braking force to the components is communicated to a driver. To inform the driver about the distribution of the braking force, without this requiring the driver to look away from the traffic area ahead, in the case of a change in distribution of braking force, a haptically perceptible signal force is briefly superimposed, via the actuator, on a restoring force acting upon the pedal.
