The invention belongs to the technical field of road safety, and provides an early warning method and system for a steering dead angle of a truck, and the method achieves the prompt early warning of a driver and the step switching of the whole early warning process through the judgment of the wheelbase, the minimum turning radius, the steering angle of an inner front wheel, the change rule of the steering angle of the inner front wheel and the like. The flexibility of the early warning process is improved, excessive calculation content during unnecessary early warning is avoided, and meanwhile, the accuracy of early warning is ensured; when the steering angle of the inner front wheel is continuously increased within the preset time period, the position of the inner front wheel is calculated, the position of the inner rear wheel is calculated according to the position of the inner front wheel, then the steering path of the inner rear wheel is obtained according to the positions of the inner rear wheel at all moments, and early warning is conducted on passersby. The problem that the steering path is affected by differences of inner wheels of different sizes exists in vehicles of various sizes and scales.
本发明属于道路安全技术领域,提供了一种关于货车转向死角的预警方法及系统,本发明通过判断轴距大小、最小转弯半径大小、内前轮转向角大小及内前轮转向角变化规律等,实现对驾驶人员的提示预警以及整个预警过程的步骤切换,提高了预警过程的灵活性,避免了不必要预警时的过多计算内容,同时保证了预警的准确性;在内前轮转向角在预设时间段内持续增大时,计算内前轮的位置,并且根据内前轮的位置计算内后轮的位置,然后根据所有时刻的内后轮的位置,得到内后轮的转向路径,对路人进行预警,考虑到了得到内后轮的转向路径时,各种尺寸规模的车辆存在不同大小内轮差对转向路径影响的问题。
