Abstract
A test method of wheel speed simulation and acquisition equipment for an EPB rear wheel anti-lock brake test is provided. The equipment includes a master computer, wheel simulation sets and an EPB system with a wheel anti-lock brake function, where the master computer includes a motor rotating speed control module, an EPB-required signal simulation module and a target wheel speed calculation module; the wheel simulation sets include motor drivers, motors, gears and wheel speed sensors; outputs of the wheel speed sensors are connected into the EPB system; the motor rotating speed control module is connected with the motor drivers; the EPB system to be tested includes EPB calipers, pressure sensors are arranged in the EPB calipers; the target wheel speed calculation module calculates a target wheel speed and sends the target wheel speed to the motor rotating speed control module to complete the control of an actual wheel speed.
