摘要： A pot-shaped composite brake rotor for motor vehicles, which combines at least one securing component as a hub interface with at least one friction ring component (as a friction partner for at least one friction lining. Distinction is made between a torque transmission function a fixing function between the paired components by the provision of a heat-conductive joint interface between the components on one side. The components are assembled coaxially with one another and joined rotationally fixedly in the axial direction so that the securing component serves as a heat sink for the friction ring component. At least one fixing element between the components is provided separately, and this fixing element substantially exclusively (nominal load) performs a fixing function by mutual form fit by a radially directed engagement behind at least one undercut. A press-fit connection s present for torque transmission between the securing component and the friction ring component.

摘要： A system for receiving and processing satellite signals from satellites of global navigation systems, in particular for a vehicle, having a signal path includes a signal conditioning unit for conditioning received satellite signals, an analysis unit for analyzing the conditioned satellite signals, and a position determination unit for determining measured values utilizing the satellite signals provided by the analysis unit. The measured values include a position, a speed, and/or a satellite time. The system has two signal paths which are separate from one another and each process mutually independent satellite signals for a position.

摘要： A driver assistance system (10) for a vehicle includes a control unit (11), and a communication device (12) for receiving data from a server (30). The control unit (11) is configured to calculate a trajectory (T) for the vehicle on the basis of sensor data. The control unit (11) is also configured to replace the calculated trajectory (T) for the vehicle (20) with an offboard trajectory (T1) received from the server (30) under certain circumstances.

摘要： Brake system of a motor vehicle having front wheels and rear wheels having a hydraulic service brake device. The system further includes an electrically actuatable pressure-providing device, wherein the pressure-providing device is connected to the first and second wheel brakes, comprising a parking brake device having electric-motor-actuatable wheel brakes at the rear wheels, and an electronic open-loop and closed-loop control unit, wherein in a hydraulic fallback operating mode of the brake system, in the case of a brake pedal actuation by a vehicle driver, only the first wheel brakes are connected to the master brake cylinder and supplied with pressure by the driver by the master brake cylinder, while the rear wheels are braked by the electric-motor-actuatable wheel brakes.

摘要： For controlling electromechanically actuatable brakes of servo type construction, it is necessary to detect the forces acting on the abutment of the brake shoes. The abutment is therefore formed from a massive material which deforms under load, wherein measurement devices are provided which detect this deformation. The shape of the abutment is selected in such a way that the abutment has measurement gaps, the size of which changes when the abutment is loaded. The size of the measurement gaps can be sensed by means of Hall sensors or AMR sensors, for example.

摘要： A pot-shaped, cold-formed steel brake piston as a pot which is open on one side includes a base and a wall including inner and outer walls, a radially inwardly configured groove is open in a radially outward direction and forms, radially at the inside, a groove bead projection. The open side of the pot ends as a bearing for a friction pad backplate. Interfaces integrated at the inside on the end side serve a) for the fixing between friction pad and steel brake piston and b) as support bearing for spring mounting the friction pad. An aspect is a further improved steel brake piston of the new generation. The minimum inner diameter dimin is axially set back in the direction of the base by a multiple of the length of a wall thickness s, and the minimum piston inner diameter dimin is formed by the groove bead projection.

摘要： A method for actuating a solenoid valve, which is loaded with a pneumatic pressure medium, in order to reduce a pressure (psys) which is applied to the solenoid valve, where the solenoid valve assumes a closed switching position in the deenergized state and assumes a completely open switching position when it is energized with a switching current intensity (Is(p)) which is dependent on the applied pressure (psys), where a first rise current final value (I1) is predetermined, which first rise current final value is smaller than the switching current intensity (Is(p)), where the solenoid valve is energized with an actuating current which follows an actuating current profile (SV1, SV2), and where the actuating current profile (SV1, SV2) comprises a first rise phase (TA1), in which the actuating current is increased to the predetermined first rise current final value (I1), and, following said first rise phase, a first holding phase (TH1) in which the actuating current is held constant at the first rise current final value (I1).
