    Abstract: An electromechanical actuator for activating, by an actuating element, a system that transmits force by frictional locking, which actuating element at least partially produces or removes a normal force for the frictional locking, including: a housing; the actuating element, which is mounted in the housing for axial movement and is movable at least between a first axial position and a second axial position; an electronic control unit; an electromechanical rotary drive, which is controlled by the electronic control unit and which rotationally drives a shaft mounted in the housing; a wear compensation mechanism to compensate for wear of the force transmitting system, which is mounted axially movably in the housing; a transforming mechanism to transform the rotation of the shaft into an axial translation of the wear compensation mechanism, wherein the axial translation of the wear compensation mechanism acts on the actuating element, as described herein.

    Abstract: A compressed-air supply device for commercial vehicles is provided. The compressed-air supply device may be connected electrically to an electronic control device that may actuate at least one control valve. The control valve has at least one inlet, one ventilating connection and one outlet. The compressed-air supply device has a control line which is connected to the control valve outlet and may be connected to a control inlet of a compressor and/or an inlet of a regeneration valve, has a supply line via which compressed air may be guided to the control valve inlet, and has a ventilating line connected to the control valve ventilating connection. The control valve may be ventilated via the ventilating line, and is configured such that at a predefined opening pressure in the supply line it pneumatically produces a fluid-conducting connection between the inlet and the outlet such that the control line is ventilated.

    Abstract: An apparatus for determining a speed of a vehicle, in which the vehicle includes one or more sensors to determine a distance to or a relative speed of an object in an environment of the vehicle, and in which the apparatus includes a data interface and a processing module. The data interface is configured to receive sensor data from the one or more sensors, where the sensor data indicates the distance to and/or the relative speed of the object. The processing module is configured to determine (i) a motion state of the object based on the received sensor data, and (ii) the speed of the vehicle based on the determined motion state and the received sensor data.

    Abstract: A system for controlling a commercial vehicle in a restricted area, including: an information acquisition module to acquire information from a database about the restricted area, wherein the commercial vehicle includes a sensor unit to detect objects in surroundings of the commercial vehicle, and wherein the acquired information includes cartographic data for objects in the restricted area; a detection module to detect at least one object in the surroundings of the vehicle using the sensor unit of the commercial vehicle; an identification module to identify the at least one detected object in the cartographic data; and a movement module to allow autonomous movement of the commercial vehicle in the restricted area based on the identified objects. Also described are a related commercial vehicle, a method and a computer readable medium.
