Abstract

The invention provides a quick starting method and device for a full liquid crystal instrument, and the method comprises the steps: an instrument guide program is electrified and started, a coprocessor is guided and started in the guide program, and peripheral resources are initialized through the coprocessor; a coprocessor application program is started to take over IO equipment of the processor, and connection between the processor and the vehicle-mounted ECU is established; a vehicle-mounted ECU signal is obtained through IO equipment, whether the emergency content needs to be displayed or not is judged according to an ECU signal value, and if the emergency content needs to be displayed, the emergency content is drawn through a coprocessor; the Linux kernel is booted and started through the bootstrap program, after Linux device resources are initialized, the Linux application program is started, and the 3D drawing engine is started to draw the pre-display content. Therefore, important content can be timely displayed, and the display and starting speed of the liquid crystal instrument is improved.

Description

technical field [0001] The invention belongs to the field of automobile instruments, and in particular relates to a quick start method and device for a full liquid crystal instrument. Background technique [0002] The full LCD instrument panel is a device that replaces the traditional mechanical instrument panel with a whole LCD screen to display vehicle driving information to the driver. The traditional physical pointer is cancelled, and all are displayed on the electronic screen. It can not only show the driver basic information such as vehicle speed, engine speed, and remaining fuel volume of the traditional mechanical dashboard, but also make the display effect more colorful and richer in display content, and can realize personalized settings and improve the technology of the whole vehicle feel. The full LCD instrument is not just a simple element that provides speed and vehicle speed, it can also display more important vehicle information, and even issue warning prompt...
