Automotive anti-lock brake (ABS) and traction control system (TCS)

摘要

The present invention relates to an anti-lock brake and traction control system of a motor vehicle. The hydraulic pressure transmitted through the first and second supply passages 110 and 120 and the first and second supply passages 110 and 120 transmitted to (A) and the non-driven wheel (B) is driven. Hydraulic pressure of the drive inlet (A) and the non-driven wheel (B) when the inlet valve (60) 70 and the inlet valve (60) 70 block the transmission to the non-driven wheel (A). The outlet valves 80 and 90 which are opened to lower the pressure, the return pump 100 which promotes the discharge of oil when the outlet valves 80 and 90 are opened, and slip on the driving wheel A during the TCS operation When the phenomenon occurs, the switching valve 40 for blocking the flow path connected to the drive wheel (A), and the drive wheel when the switching valve 40 is blocked In a braking device of an automobile having an ABS and a TCS composed of a priming valve 50 or the like which is opened to apply a braking to (A), the second supply passage 120 is connected to the switching valve 40 and the return pump ( By connecting to the first supply passage 110 between the 100, it is possible to shut off the switching valve 40 to prevent the oil supplied to the return pump 100 is reversely circulated to the master cylinder 30 during ABS operation. As it is configured to, it is an invention for safe and convenient operation by removing the kickback phenomenon during ABS operation.
