Publication number: 20190193702Abstract: An air brake relay valve includes an air guide unit having a movable set, a drive unit having a motor and a worm shaft, and a cam unit having a transmission member and a driven member. During a brake action, the motor rotates the worm shaft to rotate the transmission member so as to push the driven member downward to thereby move the movable set to a communicating position where a first valve opening and a second valve opening fluidly communicate with each other. When the brake action is released, the motor rotates reversely so that the driven member is moved upward and that the movable set moves, without being applied with additional force, to a non-communicating position where the first and second valve openings do not fluidly communicate.Type: ApplicationFiled: December 27, 2017Publication date: June 27, 2019Applicant: Automotive Research & Testing CenterInventors: Fu-Hsien SUN, Chien-An CHEN, Ming-Jyun LIN

Publication number: 20190193703Abstract: The method relates to a method for boosting the braking force in an electromotor operated slip-controllable vehicle brake system having electromechanical brake boosting. The vehicle brake system includes a braking-intention detection device, an electromechanically actuatable brake booster, and an electronically actuatable brake-pressure control device. In the event of a malfunction of the brake booster, the boosting of the brake pressure is alternatively assumed by the brake-pressure control device. In the event of a malfunction of the brake boosting, it is checked whether a generation and a transmission of a trigger signal representing the actuation of the braking-intention detection device from the first electronic control device of the brake booster to a second electronic control device of the brake-pressure control device is possible, and if this is so, the trigger signal is transmitted via an existing communications link between the control devices.Type: ApplicationFiled: December 10, 2018Publication date: June 27, 2019Inventors: Florian Haag, Martin Marquart

Publication number: 20190193705Abstract: An electronically controllable pneumatic brake system for a vehicle. The electronically controllable pneumatic brake system includes wheel brakes configured to brake wheels of the vehicle, wherein a service brake braking pressure can be imposed on each of the wheel brakes via pneumatic paths starting from a foot brake valve; and an electronically controllable monostable bypass valve having a first switching position and a second switching position, wherein the monostable bypass valve is disposed in a respective pneumatic path of the pneumatic paths. In the first switching position of the monostable bypass valve, a service brake braking pressure in the respective pneumatic path can be derived depending on an actuation pressure produced by manual actuation of the foot brake valve. In the second switching position of the monostable bypass valve, the service brake braking pressure in the respective pneumatic path can be specified depending on a reservoir pressure prevailing in a reservoir.Type: ApplicationFiled: July 17, 2017Publication date: June 27, 2019Inventor: Oliver Wulf
