The invention provides a vehicle digital instrument display control method, which comprises the following steps that: a signal acquired by a digital instrument display screen is displayed, and the signal displayed by the digital instrument display screen comes from signals of an ECU, a sensor and a controller in a vehicle collected by a first device or a second device; the signal is obtained by the first device, and is output to the digital instrument display screen to be displayed, and the second device does not output the signal to the digital instrument display screen and operates in a system background when the first device operates normally; wherein the first device is a system used for system normal operation, the second device is a standby system of the first device, and the seconddevice is operated only when the first device fails and cannot operate normally. Double-device instrument display is adopted, one device is displayed normally, the other device is displayed in a standby mode, the reliability of an automobile instrument display system is guaranteed, in addition, on an instrument display picture, display is conducted dynamically and statically, and meanwhile displayof oil consumption and the remaining mileage is more accurate and reasonable.

    本发明提供了车用数字仪表显示控制方法,包括:数字仪表显示屏获取的信号进行显示,数字仪表显示屏显示的信号来自于第一装置或第二装置采集车内ECU、传感器、控制器的信号;第一装置获取信号后并将信号输出到数字仪表显示屏进行显示,第二装置在第一装置正常运行时不输出信号到数字仪表显示屏并在系统后台运行。第一装置为系统正常运行是使用的系统,第二装置为第一装置的备用系统,当第一装置出现故障不能正常运行时才运行第二装置。本发明采用双装置的仪表显示,其中一个正常显示,另一个进行备用,保证汽车仪表显示系统的可靠性,另外,在仪表显示画面上,以动态和静态进行显示,同时油耗和剩余里程的显示方面更为精确和合理。
