Abstract: For the following and cruise functions, the sensor accuracy is limited and the communication between vehicles is isolatesd, which affect the following efficiency and safety. To overcome this problem, this paper applies the dedicated short-range communication technology to establish an automatic following system based on vehicle-to-vehicle cooperation, which could realize the real-time sharing and interaction of key state information between the host vehicle and lead vehicles. A set of automatic following control strategy is designed and developed to improve the efficiency and safety of vehicle following system. The real vehicle test shows that the automatic following system based on dedicated short-range communication technology can effectively realize the vehicle following function and the whole periods of automatic following are stable and reasonable. And the automatic following control strategy can control the host vehicle to follow the lead vehicle compactly and safely within a safe distance in real time.
