Vehicle-mounted head-up display system

Abstract

The invention discloses a vehicle-mounted head-up display system, a light control device is used for regulating and controlling the propagation direction of light emitted by a light generation part, so that the light generated by the light generation part passes through an image generation layer, is reflected by a windshield of a vehicle, and then is emitted to at least two eye box areas. The image generation layer is used for generating image light from emergent light of the light control device and projecting the image light to the windshield of the vehicle, and a control device is used for controlling the image generation layer and / or the light control device to project image light to each eye box area according to the vehicle state and the priority attention of generated information, wherein the image content of the image light conforms to the position of the eye box area. The vehicle-mounted head-up display system can display different images to different eye box areas in the vehicle, and can display corresponding images to different eye box areas according to the vehicle state.

Description

technical field [0001] The invention relates to the technical field of vehicle display, in particular to a vehicle head-up display system. Background technique [0002] In recent years, with the continuous development of vehicle intelligence, Internet of Vehicles, automatic driving and other technologies, the information received by mobile vehicle terminals and various expanded applications emerge in an endless stream. People want to connect all the display screens in the vehicle to flexibly display various information The demand is increasing, but the driver's line of sight is easy to deviate when performing related operations, which poses a potential safety risk. [0003] The head up display (HUD) technology can avoid the driver's distraction caused by looking down at the dashboard or other display screens during driving, improve the driving safety factor, and also bring a better driving experience. In recent years, it has also received more and more attention, and has gr...

Problems solved by technology

[0004] The existing head-up display device is realized by a free-form surface reflector. The image light generated by the image source is reflected by the plane mirror and the free-form surface reflector, and then enters the windshield. The light is reflected by the windshield and enters the user's eyes. However, this head-up display The device can only display images to the user within a certain range of viewing angles. The viewing angle is generally within 10 degrees, and the size of the displayed screen is very small. Generally, it can only display vehicle speed or direction information within a certain range of viewing angles in the vehicle, and cannot display Richer content is difficult to meet the needs of different users such as drivers and passengers, which limits the further promotion and application of head-up display devices
