It should be noted that, under the working condition of backing a car, the second vehicle carried image is not adjustable, and after the reverse gear signal disappears, the second vehicle carried image is exited according to the reverse gear delay.

Optionally, under the low-speed driving condition, the vehicle user can click to zoom in and zoom out the view in the first vehicle-mounted image according to the actual requirement, so as to obtain a better visual field observation effect
For example, in the case where the first vehicle-mounted image is as shown in (a) of fig. 8 and the vehicle user needs to observe the left front wheel region, the vehicle user may directly click on the left front wheel region view, realizing the enlarged display of the left front wheel region view as shown in (b) of fig. 8. After finishing viewing the left front wheel region, the vehicle user may click on the enlarged left front wheel region view shown in fig. 8 (b) to restore the first vehicle-mounted image to the first vehicle-mounted image shown in fig. 8 (a).
In this embodiment, by zooming in and out the target sub-view selected by the vehicle user in the first vehicle-mounted image in response to the clicking operation of the user, the vehicle-mounted image can be displayed better according to the user requirement, so that the field of view observation efficiency under the complex road condition is improved.

Optionally, a first vehicle-mounted image custom function entry is provided for the vehicle user, so that the vehicle user can adjust the display of the first vehicle-mounted image according to the driving requirement. And under the condition that a vehicle user triggers the entrance of the vehicle-mounted image self-defining function, the video image controller receives the view setting signal, generates a wheel area view, a vehicle front view, a vehicle rear view, a vehicle left view, a vehicle right view and a panoramic top view as alternative sub-views according to the video stream signal, and displays the alternative sub-views on a display. The vehicle user may make the desired view by clicking on the alternate sub-view.
After the vehicle user confirms the selection result, the video image controller receives the view selection signal, determines the sub-view to be displayed and the sub-view not to be displayed in the first vehicle-mounted image, generates view configuration information according to the display type corresponding to each alternative sub-view, and stores the view configuration information for generating the first vehicle-mounted image according to the user requirement.
In this embodiment, by setting a view that a vehicle user can customize the display of the first vehicle-mounted image, the user's demand can be responded, thereby improving the use feeling of the vehicle user.
In one embodiment, the method further comprises: generating corresponding vehicle-mounted equipment obstacle reporting information according to the undetected target vehicle-mounted equipment signal under the condition that at least one project mark vehicle-mounted equipment signal is not detected in a preset time period; the target in-vehicle device signals include video streaming signals, radar ranging signals, and alert signals.
Optionally, in response to the ignition signal, the video image controller first performs a self-test after power-up, followed by sequentially detecting the video stream signal, the radar ranging signal, and the alarm signal. If the video image controller does not detect the video stream signal, the radar ranging signal or the alarm signal within a preset time period, for example, within 300ms, the video image controller judges that the corresponding vehicle-mounted equipment fails, generates corresponding vehicle-mounted equipment guarantee information according to the failed vehicle-mounted equipment, and alerts the corresponding failure.

In an alternative embodiment, the step early warning is performed according to the distance between the target obstacle and the target vehicle when the distance between the target obstacle and the target vehicle is not greater than the early warning distance.
