摘要： A method for estimating a position of a trailer relative to a truck of a road train includes providing or obtaining a kinematic model of the road train, providing or obtaining a length estimation of the trailer, and measuring an articulation angle between the truck and the trailer. The method further includes determining a position of the trailer relative to the truck using the kinematic model, the length estimation, and the measured articulation angle.

摘要： A sensor system, for determining an angular change between a utility vehicle and a coupled vehicle trailer, includes a sensor unit having a wheel mounted so as to be rotatable about an axis, and a rotary encoder connected to the wheel and configured to detect a change in position of the wheel. The sensor system further includes a mount having at least one first fixed part configured to connect the sensor system to the utility vehicle or a part thereof, and at least one movable part connected to the sensor unit and mounted so as to be movable on the fixed part. In addition, the sensor system includes a positioning mechanism configured to provide sprung bearing of the movable part in an operating position such that the wheel of the sensor unit can be moved into contact with a vehicle trailer or a part of the vehicle trailer.

摘要： A valve arrangement of a vehicle's air suspension system has a pressure generator with a two-stage compressor drivable by an electric motor, an air dryer, and a switchover valve. A main line is connected to the pressure generator and branches into at least two first axle lines. Two bellows lines per vehicle axle each branch off from one of the first axle lines and lead via a shutoff valve to an air bellows. The pressure generator has a second connection connected to a delivery line of the pressure generator between two compressor stages of the compressor. A second main line is connected to the second connection. The second main line branches into at least two second axle lines downstream of a shutoff valve. These second axle lines are each connected to one of the branching points of the first axle lines at the axles, each via one shutoff valve.

摘要： A method for monitoring an implementation of an assistance braking specification, requested in an automated fashion by a brake system in a vehicle includes: detecting whether an assistance braking specification which is requested in an automated fashion is present; detecting an actual dynamics variable, the actual dynamics variable including wheel dynamics of at least one wheel of the vehicle and/or of a trailer, the actual dynamics variable being assigned to a wheel which is to be braked as a result of the assistance braking specification which is requested in an automated fashion; determining a reference dynamics variable, the reference dynamics variable including driving dynamics of the vehicle and/or of the trailer; and comparing the actual dynamics variable with the reference dynamics variable. When an assistance braking specification is present: a faultfree implementation of the assistance braking specification which is requested is detected if the actual dynamics variable deviates.

摘要： An antilock control method for a braking system of a vehicle has at least the following steps: upon the presence of a brake request signal, outputting a brake control signal and building up a brake pressure by a braking medium at a wheel brake of a vehicle wheel, measuring a wheel speed of the vehicle wheel to be braked, and determining a wheel slip of the vehicle wheel, upon meeting a first traction criterion or a locking tendency of the vehicle wheel, activating a wheel drive unit and applying a wheel drive torque on the vehicle wheel to increase the wheel circumferential velocity and to reduce the wheel slip until a second traction criterion is met. The brake force introduced in the wheel brake is controlled as a function of the wheel slip by releasing the brake pressure upon satisfying a first traction criterion.

摘要： The invention relates to an electronically controllable secondary brake system (46), operated by pressure medium, useable as both as a parking brake system and an auxiliary brake system, with spring brake cylinders (68a, 68b) arranged on wheel brakes of at least one vehicle axle (8), with a directly or indirectly electronically controllable brake control valve (56). The brake force of the spring brake cylinder (68a, 68b) can be reduced by a feed of pressure medium and can be increased by a discharge of pressure medium, and with an electronic brake control unit (48) for controlling the brake control valve (56) dependent on the current value of a brake value signal (SBW). The brake control valve (56) is configured as a 3/3-way proportional valve with a pressure medium inlet, a pressure medium outlet, and a working connector, which is connected via a working line (60, 66) to the spring brake cylinders.

摘要： A transverse steering method is for moving a vehicle comprising active steering to a target position. The method includes: performing distance and/or angle measurements between the vehicle and the target position enabling the derivation of location and orientation data; deriving the location and orientation data; filtering the location and orientation data into current values, which include current location values and current orientation values; performing control which derives a target steering angle from the current values; and realization of the target steering angle by acting on the active steering of the vehicle.

摘要： A method for automatic electronic control of a brake system in a vehicle includes reading a brake signal for the automatic electronic control of brakes in the vehicle, wherein requests to be implemented by the brakes are transmitted via the brake signal to bring about automatically requested target vehicle longitudinal dynamics. The method further includes determining a brake pressure distribution indicating a ratio of a front axle brake pressure of a front axle to a rear axle brake pressure of a rear axle, and providing at least a first brake pressure signal of the first electronic control unit to at least a first electropneumatic control device, taking into account the braking request signal and the brake pressure distribution for controlling the front axle brake pressure and the rear axle brake pressure, and receiving the brake pressure distribution at a second electronic control unit and storing the detected brake pressure distribution.
