The invention relates to a view checking method for an inside rear-view mirror. Comprising the following steps: 1, determining a driver R point, a driver eye point, an inner rearview mirror reflecting surface, an inner rearview mirror reflecting surface rotating center, a no-load ground plane, rear windshield glass and a rear windshield black area boundary; 2, setting a regulation view field area; 3, checking the field of view of the inside rear-view mirror; 4, checking the basic size of the mirror surface of the inside rear-view mirror; 5, checking the regulation visual field area of the inside rear-view mirror; 6, checking the visible area of the inside rear-view mirror in the rear windshield glass; 7, determining the minimum size of the mirror surface of the inside rear-view mirror; according to the method, the visual area is formed on the intersection line of the reflecting surfaces of the inside rear-view mirror by utilizing the mirror surface imaging principle on the basis of driver regulation eye points and regulation required visual field areas, the cost is reduced and the aesthetic property is improved by determining the minimum size of the mirror surface of the inside rear-view mirror, meanwhile, the visual field checking efficiency of the inside rear-view mirror is improved, and the optimal position of the inside rear-view mirror is determined; the visual field range of a driver in the vehicle driving process is guaranteed, and driving safety is guaranteed.
本发明是一种内后视镜视野校核方法。包括:一、确定驾驶员R点、驾驶员眼点、内后视镜反射面、内后视反射面旋转中心、空载地平面、后风窗玻璃、后风窗黑区边界;二、设定法规视野区域;三、校核内后视镜视野范围;四、校核内后视镜镜面基本尺寸;五、校核内后视镜法规视野区域;六、校核内后视镜在后风窗玻璃的可视区域;七、确定内后视镜镜面最小尺寸;本发明基于驾驶员法规眼点与法规要求视野区域,利用镜面成像原理,在内后视镜反射面交线形成可视区域,通过确定最小内后视镜镜面尺寸来降低成本,提升美观性,同时提高内后视镜视野校核效率,确定内后视镜最佳位置,保证车辆在行驶过程中驾驶员的视野范围,保证驾驶安全性。
