Description

Method, system and vehicle for adjusting height of head-up display image

This application claims the priority of a Chinese patent application filed with the Chinese Patent Office with an application number of 202010339033.4 on April 26, 2020, and the entire content of the application is incorporated into this application by reference.

Technical field

The embodiments of the present application relate to the field of on-vehicle head-up display systems, for example, to a method, system, and vehicle for adjusting the height of a head-up display image.

Background technique

With the continuous increase of vehicles, the pressure of driving on the road is increasing. In order to avoid accidents caused by drivers looking down at the instrument panel during driving, on-board head-up displays (HUD) have emerged. HUD uses the principle of optical reflection to project instrument information on the front windshield in the form of text and graphics, so that the driver can determine navigation, vehicle speed and other information without having to lower his head during driving, and avoid distracting the driver from the road ahead. , Improve driving safety.

In order to ensure the comfort of driving, the height of the head-up image displayed on the on-board head-up display can be adjusted. However, the height adjustment motor of the on-board head-up display is generally non-stepless adjustment, and the height of the head-up display image is often adjusted in different gears. Due to the noise problem, the change time between multiple gears cannot reach a state that is not noticeable by the human eye. The height adjustment of the head-up display image is often used in the form of a hard switch or a soft switch, and the form of addition and subtraction is adopted. Each time a button is pressed, a gear can be raised or lowered.

However, the height adjustment through addition and subtraction is slow and inefficient. At the same time, when other functions in the vehicle are all adjusted by soft switches in the form of a progress bar, it is difficult to adjust the height adjustment switch of the head-up display image that is adjusted by the addition and subtraction. It forms a more beautiful interface with other soft switches and limits the scalability of the height adjustment switch. When the height adjustment switch adopts a soft switch in the form of a progress bar, due to the limitation of the height adjustment motor, the gear displayed on the interface during the dragging process of the progress bar will slowly jump or even jump left and right, and the head-up display image cannot be displayed clearly and accurately. The high level of the user experience seriously reduces the user experience.

S208: Control the height adjustment progress bar to display height according to the height gear corresponding to the height adjustment instruction.

When the actual height gear included in the height adjustment feedback information is consistent with the height gear corresponding to the height adjustment command, it can be considered that the adjustment height of the head-up display image is the same as the adjustment result expected by the user, that is, the user is on the height adjustment progress bar. The gear display after the adjustment operation is the same, so the display on the height adjustment progress bar is not modified at this time, so that the height adjustment progress bar still displays the height according to the height gear corresponding to the height adjustment command.

S209. Control the height adjustment progress bar to display height according to the actual height gear.

When the actual height gear included in the height adjustment feedback information is inconsistent with the height gear corresponding to the height adjustment command, it can be considered that the adjustment height of the head-up display image is different from the adjustment result expected by the user, so the actual height gear is adjusted at this time. The display on the height adjustment display bar is modified so that the display height on the height adjustment progress bar matches the actual height.

S210. The interface controller continues to send a height adjustment instruction to the head-up display controller until the user's adjustment operation on the displayed height adjustment progress bar is received.

After the interface controller updates the height adjustment information on the height adjustment progress bar according to the height adjustment feedback information, it continues to send height adjustment instructions to the head-up display controller at a fixed period until it receives the user's operation on the height adjustment progress bar to generate a new The height adjustment command is generated by the height adjustment information on the height adjustment progress bar, and is used to ensure that the height of the head-up display image does not jitter during the driving of the vehicle. Optionally, the above-mentioned fixed period may be 100 ms, which may be set when the vehicle leaves the factory or may be customized by the user, which is not limited in the embodiment of the present application. The use of the above operation ensures that the interface controller sends height adjustment information to the head-up display controller in the form of cycles plus events, ensuring real-time control of the height of the head-up display image.

S211: Use the time when the adjustment operation is received as the new current monitoring time, and return to step S201.
