When the first instrument display unit 12 experiences communication failure, display failure, or power failure, resulting in abnormal display of the first instrument display unit 12, the second instrument display unit 13 can provide display services for some or all of the key operating data such as vehicle operating information. This achieves redundant operation protection and system fault tolerance at the system level, ensuring reliability and safety during driving.

[0035] Optionally, based on the above embodiments, continue to refer to... Figure 1 The first piece of information includes real-time vehicle speed, battery level, gear information, and fault information. The second piece of information includes weather information, riding animations, map navigation routes, and messages from external terminal devices.

[0036] Specifically, this embodiment of the invention fully considers driving safety and human-computer interaction efficiency, adopting a strategy that clearly distinguishes the display content of the first instrument display unit 12 and the second instrument display unit 13. For example, the first instrument display unit 12 can serve as the main instrument display unit, and the second instrument display unit 13 can serve as the secondary instrument display unit. The first instrument display unit 12 can be used to display essential vehicle data necessary for driving, including real-time vehicle speed, remaining battery power for electric vehicles / remaining fuel for gasoline vehicles, current gear information, mileage, and fault alarm prompts for the entire vehicle system.
