Abstract
A vehicle braking system includes: a master cylinder; a slave cylinder communicated with the master cylinder; a vehicle behavior stabilizer communicated with the slave cylinder; first and second master cut valves, each being a normally closed valve for opening and closing a fluid flow path between the master cylinder and the slave cylinder, for making hydraulic pressures in the slave cylinder and the vehicle behavior stabilizer work in a valve closing direction; a pressure sensor for detecting the hydraulic pressure in the vehicle behavior stabilizer; and a piston controller for advancing first and second slave pistons in the slave cylinder when the hydraulic pressure on the vehicle behavior stabilizer side, detected by the pressure sensor, exceeds a predetermined value, and returning the pistons at a predetermined timing.
Claims9
A vehicle braking system comprising:
- a master cylinder configured to generate a hydraulic pressure in response to a pedal effort of a driver;
- a slave cylinder configured to generate a braking force for a vehicle using a hydraulic pressure by driving a piston that is operated with an electric actuator, the slave cylinder being connected with the master cylinder;
- a vehicle behavior stabilizer configured to generate a braking force for each wheel of the vehicle using a hydraulic pressure, the vehicle behavior stabilizer being connected with the slave cylinder;
- a master cut valve including a normally closed valve for opening and closing a fluid flow path between the master cylinder and the slave cylinder, a hydraulic pressure downstream of the master cut valve working in a valve closing direction;
- a pressure sensor configured to detect the hydraulic pressure downstream of the master cut valve;
- and
- a piston controller configured, in response to the hydraulic pressure detected by the pressure sensor exceeding a predetermined value, to advance the piston in the slave cylinder to pressurize fluid downstream of the master cut valve and then, at a predetermined timing, return the piston.
