Abstract Due to hardware-In-the-loop test method , the hardware-In-the-loop test system of bus antilock brake system was built. The system consists of three parts: Matlab/xPC target real-time environment, pneumatic brake system and vehicle dynamics model. The data of the braking force of the bus can be collected to calculate results and display. For vehicle braking parameter self-tuning fuzzy PID control algorithm was introduced in the control strategy of ABS. The braking condition of the bus in large and small adhesion coefficient road, bisectional road and joint road was tested. Test results show that the method can be used for real-time tuning of the PID parameters according to the braking condition, and the wheel slip rate stay stably in the vicinity of the best slip rate 0.2(large adhesion coefficient road)and 0.1(small adhesion coefficient road), which has good adaptability and control precision.
