A novel vehicle emergency braking control method based on parameter estimation

The braking system is a vital part of vehicle safety. In order to improve the vehicle stability during emergency braking, a parameter-estimation-based emergency braking control approach is proposed to enhance vehicle stability. The state factors influencing the braking stability of the vehicle are obtained from the dynamic analysis of the constructed vehicle model, and an emergency braking control method that incorporates these state characteristics is developed. The radial basis function neural network and the extended Kalman filter method are utilised in the emergency brake control strategy to estimate the state parameters that are difficult to get directly. The simulation results indicate that the performance of parameter estimation-based emergency braking control surpasses that of conventional emergency braking control by 73.45%, with the relative error between parameter estimation and the actual state value maintained within 1%.
