A vehicle platoon cooperative control system based on digital twin was proposed, considering the longitudinal and lateral motion. The proportional-integral-derivative (PID) control was designed to ensure stable driving of the convoy. The linear quadratic regulator (LQR) control was designed to ensure the lateral lane tracking performance. A digital twin simulation scenario was build using Prescan, TruckSim, and Matlab/Simulink, and the longitudinal following and lateral lane tracking performance of vehicle queues was dynamically simulated based on longitudinal and lateral control. The digital twin comprehensively debugs and optimizes the control strategy and parameters by remotely controlling the vehicle platoon and monitoring indicators such as longitudinal and lateral velocity, lateral position and yaw angle deviation of the platoon. The simulation results show that the digital twin driven truck platoon control system has good tracking performance and lane-keeping performance.
