Abstract

The invention provides a head-up display system. The head-up display system comprises an image source group, a curved mirror, a projection image source, a light control device and an auxiliary driving controller, wherein the auxiliary driving controller is respectively connected with the projection image source and multiple image sources in the image source group; and when prompt content needs to be displayed, the auxiliary driving controller selects a target image source from the projection image source and the multiple image sources in the image source group, and outputs the prompt content to the target image source, so that the target image source is enabled to display the prompt content. According to the head-up display system provided by the embodiment of the invention, imaging can be respectively carried out at multiple imaging positions at different distances from the reflection device, so that the image formed by the image source can be attached to objects at different distances, and the attaching effect is improved; and the light control device can be arranged in a large range, so that a large-area projection imaging area is formed on the surface of the reflection device, large-range imaging is realized, and the display effect of the reflection device can be improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a head-up display system. Background technique [0002] HUD (head up display, head up display) technology can avoid the driver's distraction caused by looking down at the dashboard during driving, which can improve driving safety and bring a better driving experience. Therefore, HUDs that use car windshields for imaging are receiving increasing attention. [0003] Augmented reality head-up display (AR-HUD) uses a specially designed internal optical system to reasonably and vividly superimpose and display some driving information in the driver's line of sight, thereby further enhancing the driver's perception of the actual driving environment. The rise of AR-HUD has put forward higher technical requirements for the HUD industry. [0004] Based on the principle of AR-HUD, the image projected by the image source needs to fit perfectly with the real environment or real objects, su...
