The invention provides a vehicle blind area early warning method. The vehicle blind area early warning method comprises the steps that the current steering angle alpha of a vehicle is recognized; according to the steering angle alpha and the vehicle body size information, the steering radius of the vehicle is calculated, and the steering radius comprises the steering inner radius r and the steering outer radius R; according to the steering radius, a plurality of different projection areas are divided on a to-be-driven area in the steering direction; and projecting preset projection information in the different projection areas. According to the vehicle blind area early warning method, the driving dangerous area during steering of the vehicle can be specifically divided into different areas, the different areas have different danger degrees, and different reminding modes are carried out according to the different areas. Moreover, other sensors are not needed, high sensitivity is achieved, calculation and storage resources of the vehicle can be saved, and safe driving of the vehicle is ensured.

    本发明提供了一种车辆盲区预警方法,包括:识别所述车辆当前的转向角α;根据所述转向角α以及车身尺寸信息,计算所述车辆的转向半径,包括转向内半径r和转向外半径R;根据所述转向半径,在所述转向方向的待行驶区域上划分若干不同的投影区域;在所述不同的投影区域内投射预设的投影信息。本发明中的车辆盲区预警方法能够将车辆转向时的行驶危险区域具体划分成不同的区域,不同的区域具有不同的危险程度,并针对不同的区域进行不同方式的提醒方式。并且,无需借助其他的传感器,具有较高的敏感度,同时也能够节约车辆的计算和存储资源,确保车辆的安全行驶。
