ABSTRACT:
An electrically driven vehicle brake comprises a brake piston, which acts on at least one friction lining and can be displaced out of an initial position into an actuation position, in which the brake piston abuts the friction lining against a rotating member of the vehicle brake which is to be connected, fixed against rotation, to a wheel of the motor vehicle, and a transmission unit, driven by an electric motor and acting on the brake piston to actuate the brake piston, wherein the electric motor is to be triggered by an electronic control unit, which is also set up to detect performance parameters of the vehicle, the electric motor and/or the vehicle brake. The electronic control unit is set up and programmed to trigger the electric motor by means of a control and evaluation program running in it in such a way that the brake piston is displaced in response to the detecting of at least one predetermined operating condition in a first direction into its actuation position, in which the at least one friction lining abuts against the rotating member, and the brake piston is then displaced by a path corresponding to a predetermined, desired brake release play in a second direction opposite the first direction, into its initial position. If the vehicle brake additionally comprises a device for fixing the initial position of the brake piston, which fixes the initial position of the brake piston in such a way that a predetermined, desired brake release play is kept constant during the operating life of the brake, the electronic control unit is set up and programmed to trigger the electric motor by means of a control and evaluation program running in it in such a way that an element of the transmission unit acting on the brake piston on electrical actuation of the brake is displaced in response to the detecting of at least one predetermined operating condition in a first direction into its actuation position, in which the brake piston actuated by the element abuts the at least one friction lining against the rotating member. The element is then displaced by a path corresponding to a sum made up of the predetermined, desired brake release play and a predetermined, desired distance between the element and the brake piston when the brake is not actuated in a second direction opposite the first direction into its initial position.
