Abstract

The invention relates to a quick response method and device of a vehicle-mounted display system based on an operating system. The vehicle-mounted display system comprises a liquid crystal instrument,and the method comprises the following steps that S1, a first trigger signal is received, the vehicle-mounted display system pre-starts an operating system and is connected with a power supply of theliquid crystal instrument, and pre-starting of the operating system only comprises running of the operation system kernel and loading of files; and S2, a second trigger signal is received, and the liquid crystal instrument is controlled to display a corresponding graphic picture by the vehicle-mounted display system according to the second trigger signal. According to the method, the operating system is pre-started in advance according to the first trigger signal, the kernel is operated, and preparation is made for quickly displaying the driving information. And when the second trigger signalis received, the liquid crystal instrument can obtain a quick response without waiting, so that the satisfaction degree of a user is greatly improved.

Description

technical field [0001] The invention relates to the technical field of automotive electronic control, in particular to a quick response method and device for a vehicle-mounted display system based on an operating system. Background technique [0002] With the development of Internet of Vehicles technology, electrification, intelligence, and lightweight of vehicles have become the general trend. Users have higher and higher requirements for the safety and personalization of the vehicle display system, not only requiring the vehicle display system to have a high-definition picture and a three-dimensional human-computer interaction interface, but also requiring the system to respond in real time and accurately. [0003] At present, the LCD screen technology is becoming more and more mature, and the cost is getting lower and lower. The vehicle display system makes full use of the LCD screen to display driving information more vividly. At the same time, in order to improve the i...
