Research on Co-simulation of Anti-lock Brake System Based on Carsim and Simulink

In order to explore the braking effect of the Anti-lock brake system (ABS) control algorithm, a joint simulation study of anti-lock brake based on Carsim and Simulink was carried out. First, use Carsim to design and build a two-axis vehicle model; then use Simulink to build a slip rate model, a hydraulic brake model and an ABS controller model, and import the non-ABS control, logic threshold control and PID control into the ABS controller; Finally, the joint simulation interface of Carsim and Simulink was connected, and the joint simulation experiment of ABS with an initial speed of 60km/h was carried out on the open road. Co-simulation results show that: (1) The car wheels without ABS control lock and rollover occurs, while the logic threshold control and PID control have no wheel lock phenomenon and can stop normally; (2) PID-controlled ABS slippage The rate overshoot, braking time and braking distance are reduced by 48%, 3.6% and 1.7% respectively compared with the logic threshold control ABS, which has a better braking effect.
