Problems solved by technology

However, when the original combination meter is damaged during the use of the vehicle, causing the mileage information to be displayed incorrectly or lost, even if the diagnostic instrument is used, the accurate mileage cannot be input.
[0004] In the existing technology, there is a method of mutual backup through the vehicle controller and the combination meter, but the method proposed at present still has the inaccurate display of the meter mileage, or when the market uses the replacement method to troubleshoot, the spare parts will be mistaken. Backup of mileage leads to unrecoverable problems

Abstract

The embodiment of the invention discloses a mileage backup method and device and a vehicle, and relates to the technical field of automobile electronics, by adopting the backup method, a diagnostic instrument is not needed, the operation is convenient, and the problem that the mileage of spare parts is mistakenly backed up to cause unrecoverability when a replacement mode is used for troubleshooting in the market can be avoided. The mileage backup method comprises the steps that after a vehicle is powered off, the controller locally stores instrument mileage data sent by an instrument when thevehicle is powered on as controller mileage data; after a vehicle is powered on, a controller sends a mileage backup signal to an instrument when receiving a trigger signal of a key with a mileage backup activating function and sends locally stored mileage data of the controller to the instrument, and then the instrument stores the mileage data, sent by the controller, of the controller accordingto the mileage backup signal.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a mileage backup method, device and vehicle. Background technique [0002] As an important controller in the vehicle, the combination instrument can not only display the status of other controllers, but also store important information of the vehicle, such as vehicle speed information, fuel consumption information, mileage information and so on. Among them, the mileage information of the whole vehicle is an essential parameter of the whole vehicle, and other controllers also need this parameter for related calculations. The instrument can calculate the corresponding fuel consumption, cruising range, etc. of the whole vehicle through this parameter, so that the driver can understand the whole vehicle The driving status of the vehicle, so that the driver can perform regular maintenance on the vehicle to ensure the long-term high-efficiency operation of the vehicle.
