Intelligent System of Vehicle Brake on Ice and Snow Road

Based on the slip ratio error a PID logic threshold of vehicle ABS controller is established using MATLAB software. In the controller, the input parameters are vehicle velocity, wheel velocity, and the output parameter is the slip ratio. The vehicle brake performance using the ABS controller on ice-snow road is analyzed. Base on a vehicle parametric dynamics simulation model in Carsim software, the ABS controller is verified. Simulation results show that the PID logic threshold ABS controller can effectively improve the vehicle braking performance on ice and snow road, and the vehicle handling stability and driving safety are greatly improved.
