摘要： A compliance unit (8) for use in an hydraulic braking system is disclosed which is adapted to absorb hydraulic fluid from a master cylinder (1) during normal braking and, in the event that a fault in the braking system is detected the unit is adapted to return fluid to the master cylinder (1). The compliance unit (8) therefore effectively decreases its compliance in the event of a fault. The unit (8) may comprise a pair of pistons (14, 15) working in a stepped bore against a first and second biasing force, with a third variable biasing force provided to cancel out the second biasing force during normal operation to provide an increased compliance.

摘要： The invention is directed to a pressure supply system which has a fluid pump, an electric motor for driving the fluid pump to supply a hydraulic pressure in proportion to a current fed to the motor, and an accumulator for accumulating the hydraulic pressure supplied from the fluid pump. The pressure supply system includes a current detection device which detects the current fed to the motor, and a malfunction detection device which detects a malfunction of the pressure supply system on the basis of the output of the current detection device. The malfunction detection device is adapted to determine that the malfunction occurs when an increasing rate of the current fed to the motor is less than a predetermined rate, preferably after a predetermined time elapsed from the time when the current initially fed to the motor. The pressure supply system may further include such a warning device as a lamp or a buzzer, which will be activated when the malfunction detection device detects the malfunction of the system.

摘要： A device for detecting and discriminating operating faults in an electrical power supply circuit comprises a control circuit integrating a power transistor controlling the electric supply of a load, detectors and a logic circuit connected to a computer by two lines, an input/output control line and a selection line. The computer selectively and successively controls, by specific combinations of logic signals applied on the input/output control line and the selection line, several logic sub-circuits for the detection and identification of operating faults in the power supply circuit of the load, such faults being permanent control, short circuit and open circuit, the circuit in return imposing on the input/output control line logic levels representative of the presence of absence of operating faults, during the time intervals in which the computer is configured to read these levels. For a plurality of the power supply circuits, the selection line is common to all such power supply circuits. Application may be made to the diagnosis to the operating states of electromechanical valves forming part of a wheel anti-locking device on a vehicle.

摘要： In a antiskid control system for automobiles having two braking force control circuits arranged in parallel, these two lines of control circuits are connected to a control relay of a braking force release solenoid valve such that the braking force may be relieved only when said two control circuits provide a braking force release signal simultaneously. SUch being the case, should any one of the two braking force control circuit lines go wrong in such a manner as to cause a braking force release signal, at least the minimum function is ensured of adjusting the braking force by pressure of a foot with the aid of the working of the other control circuit line to thereby provide extraordinary safety against any accidents that may otherwise result in disaster.

摘要： The disclosure relates to a sensor assembly for a vehicle, comprising: a speed sensor for each vehicle wheel that detects an rpm-dependent and/or rotational-speed-dependent physical variable, which is used to ascertain speed information; a primary control unit, which analyses the speed information to perform first braking functions; and a secondary control unit, which analyses the speed information to perform second braking functions. A control unit is arranged positioned close to each of the vehicle wheels, and is connected to the speed sensor associated with the corresponding wheel and receives a sensor signal and determines the speed information for the corresponding vehicle wheel, the primary control device and a further control device receiving the speed information ascertained for analysis in real time, and the control devices making the speed information ascertained available in the form of first sensor data to a central network over a databus for distribution in the vehicle.

摘要： A valve system includes a control module on a tractor portion of a vehicle adapted to receive a supply pressure as a control module supply pressure of the pneumatic fluid, receive a control module control pressure of the pneumatic fluid, and deliver a control module delivery pressure of the pneumatic fluid based on the control module supply pressure and the control module control pressure. A park control module selectively transmits the pneumatic fluid at the supply pressure based on a park brake control signal. A supply glad-hand fluidly communicates the selectively transmitted supply pressure of the pneumatic fluid to supply a brake on an associated trailer portion of the vehicle. A control glad-hand fluidly communicates the control module delivery pressure of the pneumatic fluid to control the brake on the associated trailer portion of the vehicle. An exhaust valve, which fluidly communicates with both the selectively transmitted supply pressure and the control module delivery pressure, exhausts the control module delivery pressure of the pneumatic fluid from the control glad-hand.

摘要： A brake ECU brings master cut valves into an open state and brings holding valves into a closed state, thereby controlling a master cylinder and wheel cylinders to communicate to each other when a magnitude of a hydraulic pressure detected by an accumulator pressure sensor has decreased to a value less than a predetermined value set in advance. On the other hand, the ECU maintains holding valves in an open state, and controls an accumulator and the wheel cylinders to communicate to each other via linear control valves. Then, the ECU determines in which brake system a failure occurs out of a brake system for a front right wheel, a brake system for a front left wheel, and brake systems for rear right and left wheels based on changes in hydraulic pressure detected by a sensor, a master cylinder pressure sensor, and a control pressure sensor.

摘要： A method for circuit separation testing in a double gearwheel pump having two gearwheel pumps includes charging one of the two gearwheel pumps with pressure and measuring the pressure build-up in the charged gearwheel pump and/or the pressure-build up in the other gearwheel pump. The pressure build-up is preferably realized by the gearwheel pump itself. The gearwheel pumps have a common pump shaft and are preferably configured as hydraulic pumps of a hydraulic vehicle brake system with slip control. The method detects any leak at the leadthrough of the pump shaft through a partition wall between the two gearwheel pumps.
