Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] Such as figure 1 As shown, in one embodiment, a kind of car reversing video display method is provided, and this method specifically comprises the following steps:

[0043] Step 102, detecting a backing signal.

[0044] In this embodiment, the reversing signal is detected by detecting the level of GPIO (GeneralPurposeInputOutput, general-purpose input / output). When the level of the GPIO is detected to be a high level, the reversing signal is detected; otherwise, the reversing signal is not detected. .

[0045] Step 104, when a reversing signal is detected, determine the running phase of t...

Abstract

The invention relates to a vehicle-mounted reverse video display method. The method comprises the steps that a reverse signal is detected; when the reverse signal is detected, the operation phase of a vehicle-mounted system is determined; when the vehicle-mounted system does not complete boot, a reverse system is loaded through a guide program; a reverse video is displayed through the reverse system; and the reverse system and the vehicle-mounted system share a processor. When vehicle-mounted system does not complete boot, the reverse system dedicated to a reverse task is loaded through the guide program. The loading speed of the reverse system is faster than that of the vehicle-mounted system, so that the reverse video can be quickly displayed. In addition, the invention further provides a vehicle-mounted reverse video display device.

Description

technical field [0001] The invention relates to the technical field of vehicle electronics, in particular to a vehicle reversing video display method and device. Background technique [0002] For the in-vehicle system, when the user puts down the gear and enters the reverse state, the system needs to quickly display the reverse video in order to reverse the vehicle. [0003] The traditional technology provides a dual-system reversing solution, which uses two independent processors to run the reversing system and the normal on-board system respectively, and the two systems operate synchronously without interfering with each other. In the case of receiving a reversing signal when the system starts, the smaller reversing system can be quickly activated and the reversing video can be quickly displayed. However, this kind of reversing solution needs to use two processors, which increases the cost compared with the reversing system with a single processor. [0004] In the tradit...
