摘　　要：本文采用的是一种硬件在环仿真技术,将实物汽车嵌入到仿真系统中,利用单轮模型相关理论依据求出轮胎即时转速,将转速信号送入实物汽车ECU中,ECU便控制压力调节电磁阀动作,以达到调节制动油路压力的目的,仿真计算机采集回压力信号,达到跟踪轮速的目的,从而也就实现了跟踪汽车纵向滑移率的目的。This paper introduces a method for building a Hardware-in-the-loop Simulator of ABS with a real ear embedded in the system. The system utilizes the theory related to the single wheel model to calculate instantaneous rotate speed of the wheel , and then transmits the signal of the rotate speed into the ECU of the real ear. Then the ECU eontrols the eleetromagnetie valve to act, in order to modulate the pressure of the break pipe. Our simulator is supposed to eolleet the signal of the pressure baek, for the sake of tailing after the instantaneous rotate speed of the wheel. So that the course eventually realize our goal of tailing after the portrait slip rate.
