摘要：
Based on the lateral controller and longitudinal controller model, including the corrected preview driver model, acceleration control model, throttle control model and brake control model, the Matlab/Simulink and CarSim vehicle co-simulation platform is established and its feasibility is analyzed and verified. The platform is used to simulate the cooperative adaptive cruise control (CACC) fleet vehicle driving safety under four scenarios: emergency braking, communication delay, start-up, deceleration and inserting a lane change vehicle in front of the team. The simulation found that the platoon can achieve better emergency collision avoidance during emergency braking; in the case of communication delay, the team can still ensure driving safety; the starting and slowing conditions of the platoon are relatively stable, but the acceleration is not stable, which is not conducive to the platoon and the comfort of the rear vehicle; when inserts vehicles of different speeds in front of the team, the team can respond in time and eventually restore the safe driving distance.
