| Abstract: | In this paper, an intelligent driver model with lateral safety will be designed to solve the lateral safety problems faced by intelligent vehicles. The system consists of three modules: steering control module, speed control module and decision-making module. The lateral safety problems include: firstly, the lateral stability of the vehicle in the steering process is improved by adding major constraints to the steering controller to reduce the risk of vehicle sideslip, roll and sideslip; secondly, in the lane-changing scenario, the decision-making module analyses the environment and calculates the speed and the trajectory of the lane-changing. The simulation results show that the intelligent driver model improves the lateral safety of the vehicle. |
