Publication number: 20190084538Abstract: A braking system with function of anti-somersault, comprising: a hydraulic unit, a piston, a drive unit, a suspension travel sensor, and an ECU. During braking, according to a suspension travel signal generated by the suspension travel sensor, the ECU is able to determine whether a vehicle with short wheel base and high centre of gravity tends to be subject to forward somersault or not. Once confirmed, the ECU immediately sends a control signal to the drive unit, so as to drive the piston move towards a pressure releasing direction, such that fluid pressure on the downstream side of the hydraulic unit is blocked from changing. Moreover, further increase of the piston's displacement increases fluid volume in an oil chamber of the hydraulic unit so as to largely reduce the downstream fluid pressure. Consequently, braking force applied to the vehicle by the braking caliper decreases, and the forward somersault is prevented.Type: ApplicationFiled: November 16, 2017Publication date: March 21, 2019Inventors: NUI WANG, YUNG-SEN HUANG, KUEN-CHIH LAN
