The invention discloses a blind area detection method under steering of a semitrailer, a storage medium, a processor and the semitrailer, belongs to the field of vehicles, and aims to solve the problems that when blind area detection under steering of an existing semitrailer is carried out, misjudgment is generated when the distance between a target object and a body of the semitrailer is estimated, and alarm delay is caused. And accidents caused by the fact that a driver fails to make avoidance actions in time are avoided. The invention discloses a method for detecting a blind area under steering of a semitrailer. The method comprises the following steps: acquiring a yawing angle difference between a traction headstock of the semitrailer and a trailer body of the semitrailer, and a transverse distance and a longitudinal distance from a target object to a reference point of the traction headstock; and calculating the shortest distance between the target object and the trailer body of the semitrailer based on the yaw angle difference, the transverse distance and the longitudinal distance. According to the invention, whether the target object is in the preset distance range can be determined more accurately, so that a driver can take measures in time to avoid accidents when the target object is in the preset distance range.
本发明公开了一种半挂车转向下盲区检测方法、存储介质、处理器及半挂车,属于车辆领域,以解决现有的半挂车转向下盲区检测时会对目标物与挂车的车身的距离估算时产生误判而造成报警延迟,驾驶司机未能及时做出规避动作导致事故发生的问题。本发明的一种半挂车转向下盲区检测方法,包括获取所述半挂车的牵引车头和所述半挂车的挂车的车身之间的横摆角度差、目标物到所述牵引车头的参考点的横向距离和纵向距离;基于所述横摆角度差、所述横向距离和所述纵向距离计算所述目标物到半挂车的挂车车身之间的最短距离。本发明可更加准确的确定目标物是否在预设距离范围内,以保证目标物在预设距离范围内时司机可及时采取措施避免事故发生。
