Embodiment 1

[0028] This example provides a vehicle-mounted head-up display system, such as figure 1 As shown, including photoreceptor a and micro control unit b;

[0029] The photoreceptor a is used to detect the ambient brightness of the car and transmit it to the micro control unit b in the vehicle head-up display system;

[0030] The micro-control unit b is used to compare the ambient brightness with the preset brightness after acquiring the ambient brightness; when the ambient brightness is greater than or equal to the preset brightness, select a high-visibility user interface projection display; When the ambient brightness is lower than the preset brightness, a soft and comfortable user interface projection display is selected.

[0031] Wherein, a storage module is provided inside or outside the micro-control unit b, and the high-visibility user interface and the soft and comfortable user interface are stored in the storage module. According to the ambient brightness detected by th...

Embodiment 2

[0036] Such as image 3 As shown, this example will specifically explain the user interface projection display method of the vehicle-mounted head-up display system provided by the present invention, which includes the following steps:

[0037]S1. Environmental brightness detection step: Use photoreceptor a to detect the ambient brightness of the car, and send it to the micro control unit b (English abbreviation: MCU, English full name: microcontrolunit) in the vehicle head-up display system; In the process of installing the vehicle-mounted head-up display system, there is no need to install the system, just read the data of the photoreceptor a through the bus.

[0038] S2. User interface projection display step: after the micro-control unit b acquires the ambient brightness, compare it with the preset brightness; when the ambient brightness is greater than or equal to the preset brightness, select a high-visibility type The user interface 1 is projected and displayed; when th...

Abstract

The invention provides a vehicle-mounted head rising display system and a user interface projection display method thereof in order to solve the problem that due to the fact that an image of an existing vehicle-mounted head rising display system is too dark, display content of a projected user interface can be hardly distinguished, or due to the fact that the image is too bright, discomfort is generated. The user interface projection display method comprises the steps that environment brightness is detected, wherein a photoreceptor is adopted for detecting the environment brightness of a car and transmits the environment brightness to a microcontrol unit in the vehicle-mounted head rising display system; user interface projection is displayed, wherein after the microcontrol unit acquires the environment brightness, the environment brightness is compared with preset brightness, when the environment brightness is larger than or equal to the preset brightness, the high-visual-cognition user interface projection is selected to be displayed, and when the environment brightness is smaller than the preset brightness, the mild and comfortable user interface projection is selected to be displayed. According to the method, the clear degree of a user interface and the comfort of human eyes can be comprehensively considered according to different environment brightnesses, and the high-visual-cognition comfortable user interface is automatically switched.

Description

technical field [0001] The invention relates to the field of vehicle-mounted head-up displays, in particular to the field of user interface display therein. Background technique [0002] Vehicle-mounted head-up display system (English full name: HeadUpDisplay, English abbreviation: HUD), HUD is equivalent to a light projection device, which needs a light source to project HUD information. Generally, LED light groups are used as light sources and the principle of optical reflection is used. The projection position is located at In front of the driver, the user interface composed of text and images is projected on the front windshield and reflected into the driver's eyes, forming a virtual image with distance, size, color and content. When the driver looks forward, he can easily integrate the external scene with the data displayed on the HUD. The HUD is designed so that the driver does not need to look down at the display data of the instrument, and always keep the head up po...
