The present invention provides a longitudinal collision avoidance reminding and automatic following integration system and a method, and belongs to the vehicle collision avoidance field. The system comprises a collision avoidance mode selection unit, a sensing unit, a central control ECU unit, a reminding unit and an execution unit. The sensing unit obtains the type and number of front barriers, the position of a target vehicle in a lane line, the relative speed and the relative distance of an own vehicle and the front barriers, sends the obtained information to the central control ECU unit, carries out the comprehensive determination of a safe state by a D-S evidence theory, and finally determines the number of the front barriers, the relative distance vrel, the relative speed srel and an acceleration a of the own vehicle and the front target vehicle, thereby reducing the false alarm situations of a vehicle-mounted radar and a vehicle-mounted camera furthest. The central control ECU unit generates an instruction, and the reminding unit and the execution unit execute the correlated actions. The system and method of the present invention enable the false alarm rate to be reduced and the response speed and the comfort level of the drivers to be improved simultaneously, at the same time, satisfy the collision avoidance demands on different road conditions.
