The invention provides a trailer blind area early warning method and device, a controller and a trailer. The method comprises the steps that environment data around the trailer and the turning angle of a trailer head are obtained; if a preset target object is identified from the environment data, determining the position of the target object in a vehicle body world coordinate system according to the environment data; predicting a target position of the target object at the next preset moment according to the position of the target object in the vehicle body world coordinate system; determining a dangerous area around the trailer according to the turning angle; and if the target position is in the dangerous area, outputting an alarm prompt. Through real-time environment perception, target object position prediction and dangerous area evaluation of trailer turning, the risk of blind area accidents of the trailer is reduced, the driving pressure of a driver is relieved, and the driving safety is improved.
本申请提供一种挂车盲区预警的方法、装置、控制器及挂车,该方法包括:获取挂车周围的环境数据和挂车车头的转弯角度;若从环境数据识别到预设的目标物体,则根据环境数据,确定目标物体在车身世界坐标系下的位置;根据目标物体在车身世界坐标系下的位置,预测目标物体在下一预设时刻的目标位置;根据转弯角度,确定挂车周围的危险区域;若目标位置处于危险区域内,则输出报警提示。通过实时环境感知、目标物体位置预测和挂车拐头的危险区域评估,减少挂车的盲区事故的风险,减轻驾驶员的驾驶压力,提高行车安全性。
