The present invention discloses a test method of wheel speed simulation and acquisition equipment for an EPB rear wheel anti-lock brake test, relates to the technical field of vehicle test devices, and solves the problems that in research and development, the efficiency of the function test is reduced and even danger exists when wheel speed information is obtained. 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. Therefore, the effect of conveniently and efficiently testing the anti-lock brake function of an EPB system of a vehicle is achieved.
