Problems solved by technology

However, this requires repeated adjustments to achieve the ideal level. This repeated adjustment process is complicated and tedious. Adjusting the seat or changing the driving posture may require readjusting the optical path to a certain extent, so the manual adjustment process has a greater safety hazard.

Embodiment 1

[0036] Such as figure 1 As shown, the present embodiment provides a vehicle-mounted head-up display system, including: a head-up display device, a pupil tracking device and a controller; the head-up display device is arranged in front of the driver for displaying images, and its position can be adjusted; the pupil tracking device Used to obtain the pupil position information of the driver; the controller is electrically connected to the head-up display device and the pupil tracking device, can receive the pupil position information, and control the head-up display device to adjust the position according to the pupil position information, so that the driver can see clearly image.

[0037] The controller of the vehicle-mounted head-up display system can control the head-up display device according to the driver's pupil position information, so that the head-up display device can be adjusted according to the driver's pupil position information, and the image is displayed accordin...

Embodiment 2

[0047] Such as figure 2 As shown, this embodiment also discloses a control method of a vehicle-mounted head-up display system using the above-mentioned vehicle-mounted head-up display system, including:

[0048] Obtain the driver's pupil position information in real time;

[0049] According to the pupil position information, the head-up display device is controlled to adjust its position, so that the driver can clearly see the image displayed on the head-up display device.

[0050] The control method of the vehicle-mounted head-up display system of this embodiment controls the head-up display device through the acquired pupil position information of the driver, replacing the current method of manually adjusting the head-up display device, which is more accurate and faster.

[0051] Specifically, obtaining the driver's pupil position information includes: obtaining the driver's seat position information and the driver's head position information; analyzing the driver's eye po...

Abstract

The invention relates to the technical field of vehicles, and discloses a vehicle-mounted head-up display system and a control method thereof. Wherein the vehicle-mounted head-up display system includes a head-up display device, a pupil tracking device and a controller; the head-up display device is arranged in front of the driver for displaying images, and its position can be adjusted; the pupil tracking device is used to obtain the driver's pupil position information; The controller is electrically connected with the head-up display device and the pupil tracking device, and can receive the pupil position information, and control the head-up display device to adjust the position according to the pupil position information, so that the driver can see the image clearly. The invention also discloses a control method using the vehicle-mounted head-up display system. The vehicle-mounted head-up display system of the present invention can adjust the head-up display device according to the driver's pupil position information, and has good imaging effect without distortion, distortion or distortion; and does not require manual adjustment by the driver, which is more convenient and safer.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle-mounted head-up display system and a control method thereof. Background technique [0002] With the development of automobile intelligence and vehicle-mounted human-computer interaction technology, car drivers need to obtain information quickly and safely. It is necessary to divert the line of sight during operation, which will cause a lack of attention to the road ahead for 1-2 seconds, which is a dangerous hidden danger. Therefore, head-up display devices that do not need to look down to view information are increasingly used in cars. [0003] At present, the existing head-up display device reflects light to human eyes through the front windshield of the vehicle, and the human eyes generate a virtual image vision projected on the front of the vehicle by reflecting the incoming light. Due to the unique refraction / reflection optical imaging system of the head-up disp...
