Embodiment Construction

[0016] See figure 1 . The vehicle-mounted Android platform of the present invention accelerates the hardware of reversing video display time and mainly includes a reversing detection module, a video chip, a camera, a CPU and a display screen. The video signal obtained by the camera is output to the display screen through the video chip, so that the picture displayed on the display screen is switched to the reversing video.

[0017] See figure 2 . The method that vehicle-mounted Android platform of the present invention accelerates reversing video display time comprises:

[0018] 1. After the car is turned off, make the Android system enter the standby state.

[0019] After installing the Android system, after the first boot, every time the car is turned off, the Android system will enter the standby state.

[0020] 2. When the car starts, wake up the Android system from the standby state.

[0021] When the car starts, wake up the system, because the system wakes up from...

Abstract

The invention discloses a method for accelerating the reversing video display time by using a vehicle-mounted Android platform, which aims to provide a method for rapidly accessing reversing videos. The method comprises the following steps of: after an engine of a vehicle is shut off, enabling an Android system to be in a standby state; after the vehicle starts up, awakening the Android system from the standby state; and detecting whether the vehicle is in a reversing state, if so, opening a video chip and a camera, carrying out encoding and decoding on reversing videos (obtained by the camera) through the video chip, and displaying the reversing videos (obtained by the camera) on a display screen. The method disclosed by the invention can be applied to Android platform based vehicles.

Description

technical field [0001] The invention relates to a vehicle-mounted Android platform, in particular to a method for accelerating the display time of a reversing video on the vehicle-mounted Android platform. Background technique [0002] In the existing reversing function design, reversing video is a very important function, which can enable the owner to observe the road conditions behind the car in time and conveniently. The existing car reversing system often divides the start-up process into multiple stages, and performs different processing in different stages, and some even add a reset circuit to assist the system to quickly enter the reversing video during the start-up stage, which is relatively complicated. And it will increase the cost. [0003] For the in-vehicle system, when the user reverses the gear and enters the reversing state, the system needs to quickly display the reversing video to facilitate reversing. However, in the state of the existing Android-based ca...
