Embodiment Construction

[0023] The PGU temperature overheating protection method of the head-up display of the present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0024] refer to figure 1 and figure 2 , the present invention improves the head-up display, and further proposes a method for detecting the temperature of the head-up display PGU. The head-up display is referred to as HUD, which is usually arranged on the CCB beam bracket 50 in front of the vehicle instrument. You can see important driving information such as speed, navigation, etc. without looking down or turning your head, so that the line of sight does not have to shift back and forth, and driving safety is enhanced. As the projection unit of HUD, PGU is the core component of HUD. Its function is to generate HUD output image, which is composed of light source, optical diaphragm, screen and other optical components.

Abstract

The invention relates to a head-up display PGU temperature detection method which comprises a main control system; the detection method is a method for detecting the temperature of the PGU by installing a plurality of temperature sensors connected with the main control system on a PGU screen of an HUD to obtain the temperatures of a plurality of positions on the PGU screen in real time; according to the detection method, whether sunlight reversely irradiates the PGU screen or not can be judged according to the temperatures, obtained by the multiple temperature sensors, of the multiple positions on the PGU screen. The method for detecting the temperature of the head-up display PGU has the advantages that the temperature of the PGU can be directly detected in real time, wherein whether the HUD has sunlight backlight irradiation or not is judged according to the temperature condition of the PGU.

Description

technical field [0001] The invention relates to the technical field of head-up displays, in particular to a method for detecting the temperature of a PGU of a head-up display. Background technique [0002] The head-up display is referred to as HUD. Its function is to project the driving information such as speed, navigation, and external smart devices onto the windshield in front of the driver, so that the driver can see the speed without bowing or turning his head. Important driving information such as navigation, so that the line of sight does not need to shift back and forth, which enhances driving safety. [0003] As the projection unit of HUD, PGU is the core component of HUD. Its function is to generate HUD output image, which is composed of light source, optical diaphragm, screen and other optical components. [0004] refer to image 3 The HUD imaging principle diagram shows that the HUD enlarges the image on the image source (PGU) through the geometric light path, a...
