Embodiment Construction

[0020] The present invention provides a method for quickly displaying a reversing image and a car-machine system. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] see figure 1 , figure 1 It is a flowchart of a preferred embodiment of the method for quickly displaying a reversing image in the present invention, as shown in the figure, which includes steps:

[0022] S101. Set the video memory of the car-machine system as the first display memory for storing the interface data of the car-machine system and the second display memory for storing the reversing image data;

[0023] S102. After starting the kernel layer of the vehicle-machine system, detect whether the current vehicle is in reverse gear;...

Abstract

The invention discloses a method and car machine system for rapidly starting car backing up images. The method comprises the following steps that a video memory of the car machine system is set as a first video memory used for storing car machine system interface data and a second video memory used for storing car backing up image data; after an inner nuclear layer of the car machine system is started, whether a current car is in a reverse gear state or not is detected; if the current car is detected to be in the reverse gear state, a camera is started, and the image data obtained by the camera are stored in the second video memory, the image data are read from the second video memory, and the car backing up images formed by the image data are displayed. The displaying speed of the car backing up images is high, and when the car needs backing up after the car machine system is normally used, an app service of the car machine system does not need to be started. Therefore, the car machine system is high in switchover speed and quite convenient and practical to use.

Description

technical field [0001] The invention relates to the field of car-machine products, in particular to a method for rapidly displaying a reversing image and a car-machine system. Background technique [0002] With the development of electronic technology, the application of electronic technology in the automotive field is becoming more and more extensive. Corresponding in-vehicle products have also come out one after another. At present, in-vehicle products based on the Android system, such as the Android in-vehicle system, have also become popular because of their open source nature. But the current Android car system also has certain disadvantages: the system starts slowly, which will bring a lot of inconvenience, such as the situation that the car needs to be reversed after ignition, the system has not been started, and the reversing image cannot be displayed normally. The user waits for a period of time, which not only affects the user experience, but also may bring certai...
