Problems solved by technology

[0006] As mentioned above, the conventional EWB control device has a small bore size, and the pressure measured by the EWB pressure sensor rises more than the pressure measured by the pedal pressure sensor due to the delay when the oil pressurized by the brake pedal passes through the open solenoid valve. Slow, so that the time to close the solenoid valve to run the EWB is delayed and the fast response performance of the EWB cannot be guaranteed

Abstract

The invention relates to an EWB quick response control device and a method. The EWB quick response control device comprises a pedal pressure sensor, an EWB pressure sensor and a control unit. The EWB quick response control device is characterized in that the EWB (Electronic Wedge Brake) in a hydraulic type wear compensation mode is controlled, so that the EWB has quick response performance in emergency braking. By application of the EWB quick response control device, the response performance in emergency braking of the EWB in the hydraulic type wear compensation mode can be improved to the greatest extent.

Description

technical field [0001] The invention relates to an EWB control device and method, in particular to an EWB fast response control device and method. Background technique [0002] The traditional EWB control device with hydraulic wear compensation function is for the EWB wear compensation function. As the brake pedal is pressurized, the pressure transmitted through the solenoid valve is measured when the solenoid valve is opened. The measured pressure is greater than the disc and The pressure (p) at the time of pad contact operates the EWB after closing the solenoid valve. [0003] In addition, due to the small size of the orifice of the solenoid valve, when the pressurized oil of the brake pedal passes through the solenoid valve, it is delayed and the pressure transmitted through the solenoid valve rises slowly. Therefore, the traditional EWB control device is a vehicle Also run EWB with slowly rising pressure during hard braking. [0004] Further explanation is that the ped...
