The invention relates to the technical field of vehicle cooperative self-adaptive cruise, in particular to a vehicle queue rear-end collision prevention active collision avoidance cooperative control method, and rear-end collision prevention active obstacle avoidance control is carried out through two methods of adjusting the distance between vehicles in a queue and increasing the speed of a pilot vehicle. And the displacement rule of each mass block when the mass-spring-damping system is compressed is adopted to describe the change of the expected vehicle distance during collision avoidance of the vehicle queue, and after the elastic coefficient and the damping coefficient are properly calibrated, the change curve of the expected vehicle distance has the characteristics of smoothness, rapidness and stability, so that the stability of the vehicle speed in the queue is facilitated, and the collision avoidance accuracy is improved. Under the condition that communication delay and brake delay total time are cons
