摘要： A method for performing an evasive maneuver with a commercial vehicle-trailer combination includes ascertaining that a collision between the commercial vehicle-trailer combination and a collision object is impending. The method further includes determining an evasion trajectory by which the commercial vehicle-trailer combination can evade the collision object without coming into contact with the collision object, determining a desired steering angle based on the evasion trajectory and activating an active steering system of the commercial vehicle-trailer combination in dependence on the determined desired steering angle such that the commercial vehicle-trailer combination moves along the evasion trajectory from a starting traffic lane to a target traffic lane so as to perform the evasive maneuver. The method additionally includes determining a desired vehicle deceleration and initiating an electronic braking system of the commercial vehicle-trailer combination in dependence on the desired vehicle deceleration so as to brake the commercial vehicle-trailer combination.

摘要： A discharge cut-off valve for an air compressor is provided. The discharge cut-off valve includes a hinged leaf valve within the recessed portion of a cylinder head manifold. The hinged leaf valve is rotatably anchored at a first end to a joint pin and is guided at a second end by a guide pin. In the on-load phase, the hinged leaf valve is seated over an unloader vent opening while a discharge vent opening is uncovered. In the off-load phase, the hinged leaf valve is seated over the discharge vent opening while the unloader vent opening is uncovered. As a result, compressed air is prevented from escaping the discharge port of the air compressor during the off-load phase, obviating the need for a down-stream turbo cut-off valve in an air dryer, for example.

摘要： A method for decelerating a vehicle combination including a towing vehicle having a towing vehicle brake system and at least one trailer vehicle having a trailer brake system with an anti-lock brake system includes applying, by the towing vehicle brake system, a brake pressure to pneumatically operable wheel brakes of the towing vehicle according to a desired deceleration specified by a driver, and providing, by the towing vehicle brake system, a trailer brake pressure for the trailer brake system of the at least one trailer vehicle. An electronic brake control unit of the towing vehicle brake system: detects a current actual vehicle deceleration value continuously compares the current actual vehicle deceleration actual value with a maximum deceleration, and, when the current actual vehicle deceleration value reaches or exceeds the maximum deceleration, limits the brake pressure and provides an information signal.

摘要： A pneumatic ABS valve device for a pneumatic brake system of a vehicle comprises a check valve mechanism for enabling a supply air flow from a supply port to a delivery port and blocking an air flow in the reverse direction. The check valve mechanism comprises a quick release insert disposed in an insert chamber, the quick release insert being placeable in a basic position for providing a chamber passage in the insert chamber enabling the supply air flow. The quick release insert is displaceable by an air pressure difference from the basic position into an activated blocking position, in which the chamber passage is at least diminished with respect to its basic position, in order to block an air flow from the supply port to the delivery port and enabling exhaust air flow.

摘要： A method for operating a brake of a motor vehicle with at least one electronic brake signal generator and with at least one brake control device for actuating the brake based on a brake signal of the brake signal generator includes transmitting the brake signal to the brake control device. The method additionally includes transmitting an actuation of the brake signal generator as a brake signal to the brake control device in addition to a brake pressure value.

摘要： A method for operating an electronic brake system for motor vehicles includes determining, by a brake control unit, respective brake pressures acting on wheel brakes by controlling a pressure distribution ratio of brake pressures acting on wheel brakes of a front axle to brake pressures acting on wheel brakes of a rear axle of the motor vehicle. The method further includes receiving, by the brake control unit, driver brake requests determined by a driver of the motor vehicle and/or external brake requests and determining, by the brake control unit, appropriate brake pressures. The brake control unit takes into consideration an initial pressure distribution ratio value, which is ascertained in a driver braking mode or in a pressure control mode and is stored and kept available for later consideration.

摘要： A wear monitoring device of a disk brake includes a brake disk, a first brake lining on a first face of the brake disk, and a second brake lining on a second face of the brake disk, in particular for commercial vehicles. The wear monitoring device has a first sensor unit that quantitatively ascertains the cumulative wear of the first and second brake linings. The wear monitoring device outputs, at the output connection of the first sensor unit, a first electrical output signal that is associated with the cumulative wear. A signal line is connected on the one hand to the output connection of the first sensor unit and on the other hand to an evaluating unit. The signal line is arranged in such a manner that, when a predetermined first wear limit of the first or second brake lining is reached, the signal line comes into contact with a stop.
