Windshield type HUD light path system suitable for bus

The invention belongs to the technical field of vehicle information display, and particularly relates to a windshield type HUD light path system suitable for a bus. The system comprises an imaging display unit, a curved surface reflector and a windshield. The imaging display unit is used for emitting light rays, the light rays are reflected to the windshield through the curved surface reflector, alight ray virtual image is generated behind the windshield, and meanwhile the windshield reflects the received reflected light rays to eye points of a user. According to the system, more informationcan be flexibly configured and displayed, navigation, a vehicle speed, station information and the like can be displayed on the windshield, frequent head lowering for instrument watching can be avoided, and the bus driving safety is improved. 本发明属于车辆信息显示技术领域，具体涉及一种适用于公交车的风挡式HUD光路系统，包括成像显示单元、曲面反射镜与挡风玻璃；所述成像显示单元用于发射光线，经曲面反射镜反射至挡风玻璃处，挡风玻璃后方产生光线虚像，同时挡风玻璃将接收到的反射光线反射至使用者的眼点处；本系统可以灵活配置显示更多信息，能够将导航、车速、站点信息等显示在挡风玻璃上，能够避免频繁低头看仪表，提高车
