AI Technical Summary

Technical Problem

Existing hydraulic braking equipment suffers from malfunctions due to the accumulation of contaminants in valves, affecting vehicle safety, especially in the implementation of electronic stability control functions, and existing technologies struggle to effectively remove these contaminants.

Method used

By controlling the valves and pumps in the hydraulic braking equipment through the control unit, the process of closing the target valve group, supplying hydraulic pressure and removing contaminants is implemented. The valve group is flushed with high-pressure fluid to remove contaminants, achieving cleaning without the need for additional devices.

Benefits of technology

It effectively removes contaminants from the valves, ensuring the normal function of the hydraulic braking system, improving vehicle safety and the reliability of electronic stability control, and avoiding problems such as unexpected vehicle steering caused by contaminants.

Abstract

Disclosed is a method for controlling a hydraulic brake apparatus of a vehicle. The method includes a target valve group closing process in which a control unit controls a brake device to close a target valve group that selectively includes a plurality of valves, a hydraulic pressure providing process in which the control unit controls the brake device to provide hydraulic pressure to at least one of passages isolated by closing the target valve group, and a contaminant removing process in which the control unit controls the brake device such that the target valve group is opened and a fluid flushes the target valve group. The hydraulic brake apparatus of a vehicle according to the present disclosure and the method of controlling the hydraulic brake apparatus have an effect that contaminants in valves can be removed even without additional devices by controlling the valves and pumps in the hydraulic brake apparatus.
