The invention provides an exhaust method for a vehicle brake system, which can exhaust air more efficiently in a vehicle brake system using a switching valve to shorten a flow path and reduce the size of the system, and using a bypass flow path and a check valve to ensure the flow rate of brake fluid. The exhaust method of a vehicle brake system includes: a first step of actuating a slave cylinder on a pressurization side in a state in which a switching valve communicates with the slave cylinder and a brake hydraulic pressure control device, and discharging air remaining in a flow path section from the slave cylinder to the brake hydraulic pressure control device from an exhaust hole; and a second step in which, after the first step, the slave cylinder is actuated on the pressure reduction side in a state in which the exhaust hole is closed, and the air remaining in the bypass flow path is moved into the flow path section, and after the second step, the first step is performed again, and the air moved from the bypass flow path into the flow path section is discharged from the exhaust hole.

    本发明提供一种车辆制动系统的排气方法,能够在使用了切换阀来使流路缩短且使系统小型化、且使用了旁通流路与单向阀来确保制动液的流量的车辆制动系统中,更有效率地排出空气。车辆制动系统的排气方法包括:第一步骤,在切换阀连通从动气缸以及制动液压控制装置的状态下,使从动气缸在加压侧进行作动,而使滞留在从从动气缸到制动液压控制装置的流路区段中的空气从排气孔排出;以及第二步骤,在第一步骤之后,在关闭排气孔的状态下,使从动气缸在减压侧进行作动,而使滞留在旁通流路中的空气往流路区段中移动,并且在第二步骤之后,再次进行第一步骤,而使从旁通流路移动到流路区段中的空气从排气孔排出。
