摘要： A motor vehicle brake system includes a master brake cylinder actuatable by a brake pedal and having only one pressure chamber; an electrically controllable pressure supply device; a pressure medium reservoir, under atmospheric pressure from which the master brake cylinder and the pressure supply device are supplied with pressure medium; and at least two hydraulically actuatable wheel brakes. The wheel brakes can be actuated by the master brake cylinder or by the pressure supply device. The pressure chamber of the master brake cylinder is separably connected via an isolating valve to a first brake circuit supply line. The wheel brakes are divided into at least two wheel brake groups. The first wheel brake group connected to the first brake circuit supply line, and the pressure supply device connected to a second brake circuit supply line to which the second wheel brake group is connected.

摘要： A method for ensuring integrity of data sent by a vehicle V2X communication device to a control module to ensure operational safety, including: receiving data transferred by vehicle-to-X communication by a first computing apparatus of the V2X communication device, storing the data in a data memory, forwarding the data to a second computing apparatus, receiving the data by the second computing apparatus, establishing whether an action is to be triggered for the data and, in response, transmitting the data to a comparison apparatus, carrying out a comparison test for the data provided by the second computing apparatus with the data stored in the data memory and, in response to the test being passed, outputting the data and/or a control instruction and/or a warning message by the V2X communication device to a control module. Furthermore, a corresponding vehicle-to-X device and the use of the device in a vehicle are disclosed.

摘要： A method for determining road surface conditions in a system with at least one vehicle and a data processing device. The vehicle exchanges data with the data processing device wirelessly. The vehicle has at least one sensor for determining measured values describing a road surface friction coefficient, and a computing unit. The data processing device includes a database, containing a road map having a plurality of route sections. The method includes determining measured values for a route section by the sensor, determining a first friction coefficient for the route section by the vehicle's computing unit, sending a data record, containing measured values and/or the first determined friction coefficient and a piece of information identifying the route section, to the data processing device, determining an average friction coefficient for the route section, sending the average friction coefficient determined for the route section to the vehicle, and determining the road surface condition.

摘要： An electronics housing for accommodating and making electrical contact with a printed circuit board has at least one signal contact for connection to the printed circuit board, which is in the form of a press-in contact, and at least two power contacts for electrical connection to the printed circuit board, which are in the form of press-in contacts and have a width that is greater than the width of the at least one signal contact. The at least two power contacts are longer than the at least one signal contact for easier assembly with the printed circuit board.

摘要： A brake system for a motor vehicle has electromechanical wheel brakes, a brake operating unit and a central brake control unit. The wheel brakes each have a local brake control unit. The central brake control unit is connected to the brake operating unit and the local brake control units via a first data connection. The brake operating unit is connected to the local brake control unit of at least one wheel brake via a second data connection. In a normal operating mode the central brake control unit determines at least one brake demand from first operating information, received via the first data connection and transmits control signals corresponding to the brake demand to the local brake control units. In a fallback operating mode the local brake control units actuate the respective wheel brakes basis on second operating information, received via the second data connection.

摘要： A spreader unit for a drum brake is provided with a readjustment device which ensures that the clearance remains substantially constant even in the case of wear on the brake linings. The readjustment device is arranged between actuating pistons and changes the spacing of the actuating pistons in at least one readjustment step when an actuating travel of the first and second brake shoe holders has exceeded a travel setpoint value. A thermally actuable blocking device mechanically prevents the execution of the readjustment step by the readjustment device at a temperature above a temperature setpoint value

摘要： A multi-disk brake (1) for a motor vehicle has two multi-disk mechanisms (7, 8) and an actuation device (9) for brake actuation and/or brake release of the multi-disk mechanisms (7, 8), and an electric drive (16) for translational actuation (spreading) of the actuation device, such as, in particular, the ramp unit (9). During a spreading operation, the multi-disk mechanisms (7, 8) are pretensioned in a metered manner by the actuation device and produce a desired frictional engagement, and a correspondingly reversed activation of the actuating mechanism enables a correspondingly metered brake release. By means of the electric drive (16), the action of the multi-disk brake (1) can be metered overall in a particularly precise, sensitive and compensated manner in modern vehicle topology, including all peripheral brake components and systems, including recuperation.

摘要： An electromagnetic valve whose inlet and outlet ducts are oriented transversely with respect to the valve holding bore in the valve carrier, wherein the outlet duct opens out, at a distance from the discharge of the filter element, in a portion of the valve holding bore in which the filter element has a closed sleeve portion, in order to achieve a noise reduction through targeted diversion of the flow in the direction of the outlet duct.
