Abstract: The traditional fleet only relies on radar or visual sensors for perception when implementing vehicle longitudinal platoon control, resulting in limited ability of vehicles to obtain information and unable to meet the following performance of vehicles in complex traffic environments. In order to overcome the shortcomings of radar and sensors, this paper applies the vehicle network vehicle to vehicle (V2V) communication technology to the longitudinal cooperative control system of the vehicle, and conducts data exchange through the communication between the on board unit (OBU) mounted on the vehicle. First, the control strategy of the team's longitudinal following is designed, and the distance following strategy with a fixed headway is selected, and the speed of the rear vehicle is adjusted according to the status feedback of the preceding vehicle. This method can ensure the safety of the following vehicle and improve the stability of the following vehicle. Then, based on Prescan/Simulink, the model and experimental scene of the fleet longitudinal cooperative control system are established. The simulation results prove the accuracy of the vehicle longitudinal following control strategy and the accuracy of the distance following strategy.
