Abstract
A braking system comprises at least one brake, a brake value demand mechanism which emits an operator signal when actuated by an operator, and an energy dimensioning device which supplies braking energy to the brake to actuate it, thereby producing a braking value at the brake. The braking system also includes a control unit which receives the operator signal from the brake value demand mechanism and emits a braking value signal based thereon. The energy dimensioning device receives the braking value signal and supplies to the brake the braking energy needed to produce the desired braking value at the brake. In order to eliminate hysteresis in the braking system, the control unit supplies to the energy dimensioning device a braking value signal taken from a first characteristic line of braking value as a function of braking value signal when the brake is actuated. When the brake is released, the control unit supplies to the energy dimensioning device a braking value signal taken from a second characteristic line of braking value as a function of braking value signal.
