The invention relates to a method and a system for identifying traffic light intersection vehicle automatic deceleration. The method comprises the following steps: obtaining current state information of traffic lights at an intersection where a vehicle needs to pass, remaining time information of the traffic lights keeping the current state, the current vehicle speed of the vehicle, and the distance between the vehicle and the traffic light intersection; judging whether the vehicle runs along with the front vehicle or not, if so, acquiring the speed of the front vehicle and the distance between the vehicle and the front vehicle, and calculating a first safe speed; otherwise, calculating a second safe vehicle speed; according to the driving state of the vehicle following the front vehicle, the vehicle speed is automatically controlled to be the first safe vehicle speed or the second safe vehicle speed, and the vehicle is automatically decelerated to be braked within the traffic light waiting line. According to the method, the safe vehicle speed is calculated according to the recognized traffic light related information, the current vehicle speed of the vehicle, the distance between the vehicle and the traffic light intersection, the vehicle speed of the front vehicle and the vehicle distance between the vehicle and the front vehicle, the vehicle accelerator is automatically controlled, automatic speed reduction is achieved, and accidents such as red light running and traffic collision are prevented.

    本发明涉及一种识别红绿灯路口车辆自动减速的方法及系统,方法包括:获取本车需要通过的路口红绿灯的当前状态信息,红绿灯保持当前状态的剩余时间信息、本车当前车速、本车距离红绿灯路口的距离;判断本车是否处于跟随前车行驶状态,若是,获取前车车速以及本车距离前车的车距,计算第一安全车速;否则,计算第二安全车速;根据本车的跟随前车行驶状态,自动控制本车车速至第一安全车速或者第二安全车速,自动减速至刹停到红绿灯等待线以内。本发明的方法通过识别到的红绿灯相关信息、本车当前车速、本车距离红绿灯路口的距离、前车车速以及本车距离前车的车距,计算安全车速,自动控制车辆油门,实现自动减速,预防闯红灯,撞车等事故的发生。
