Traditional vehicle collision avoidance relies only on braking by the following vehicle in order to avoid an accident. If the distance between the two vehicles is insufficient, a crash cannot be avoided solely by the following vehicle braking. To solve the problem, this paper presents a cooperative and active collision avoidance (CACA) algorithm based on vehicle-to-vehicle communication, which can help collision avoidance in the situation of insufficient distance between two vehicles through acceleration of the preceding vehicle and braking of the following vehicle. This paper created a longitudinal cooperative control model and analyzed cooperative control strategies under vehicle-to-vehicle communication. By simulation of the model in Matlab/Simulink, the result shows the CACA system can avoid some crashes in difficult situations.
