The invention discloses a vehicle cooperative collision early warning system and a control method thereof. The vehicle cooperative collision early warning system comprises a sensor module, a GPS positioning module, a base station, a communication module, a vehicle state estimation module, a vehicle state prediction module, a collision early warning judgment module, a collision early warning deviceand the like. The self-vehicle state estimation module performs Kalman filtering estimation on self-vehicle signals acquired by the sensor module and the GPS positioning module; the vehicle state prediction module predicts the position states of the vehicle and other vehicles according to the received vehicle state estimation signal and other vehicle state signals acquired from the base station;and the collision early warning judgment module judges whether the vehicle has a collision risk or not according to the received prediction result and decides whether to start the collision early warning device or not according to the collision risk, so that the driving safety performance of the vehicle is improved.

    本发明公开了一种车辆协同碰撞预警系统及其控制方法,包括传感器模块、GPS定位模块、基站、通信模块、自车状态估计模块、车辆状态预测模块、碰撞预警判断模块、碰撞预警装置等;自车状态估计模块对传感器模块及GPS定位模块获取的自车信号进行卡尔曼滤波估计;车辆状态预测模块根据接收到的自车状态估计信号以及从基站获取的他车状态信号对自车和他车的位置状态进行预测,碰撞预警判断模块根据接收到的预测结果判断车辆是否有碰撞的危险,并以此决策出是否启动碰撞预警装置,从而提高车辆的行驶安全性能。
