The invention discloses an early warning method for collision accidents during turning of a heavy truck. The vehicle is provided with a speed sensor, a steering wheel angle sensor, an information processing module, a radar and a vehicle-mounted camera. The vehicle collision early warning method comprises the following steps: when the vehicle is ready to steer, obtaining turning track information of all wheels of the vehicle through the steering wheel angle sensor and a model algorithm, and obtaining related information of obstacles around the vehicle through the radar and the camera; analyzingwhether the vehicle has a collision risk at a certain moment in the future or not according to the driving information and the related information; and if danger occurs at a certain moment in the future, reminding a driver to avoid collision accidents in a sound-light alarm mode. The vehicle collision early warning is more comprehensive when the vehicle turns and runs, and the accuracy of the vehicle collision early warning and the safety of vehicle running are further improved.
本发明公开了一种重型卡车转弯时对于碰撞事故发生的预警方法,所述车辆装有速度传感器、方向盘转角传感器、信息处理模块、雷达及车载摄像头,所述车辆碰撞预警方法包括:在车辆准备转向行驶时,通过方向盘转角传感器并通过模型算法获得该车各个车轮的转弯轨迹信息,通过雷达和摄像头获得车辆周边障碍物的相关信息;通过所述行驶信息以及所述相关信息,分析本车辆未来某个时刻是否存在碰撞危险;若未来某个时刻会发生危险,则通过声光报警的方式提醒驾驶员避免碰撞事故的发生。本发明可是车辆转弯行驶时车辆碰撞预警更为全面,进一步提高了车辆碰撞预警的准确性和车辆行驶的安全性。
