Problems solved by technology

[0004] However, when the accumulative mileage calculated by the instrument and the engine control module is inconsistent, for example, due to the replacement of the instrument, there is no restriction on the mileage reset of the vehicle, and the instrument will still display the calculated accumulative mileage, so that the instrument cannot automatically display the actual mileage of the vehicle. Make the mileage display less accurate

Abstract

The invention provides a mileage display control method. The method comprises the following steps: acquiring the wheel speed of a vehicle in real time; calculating mileage data according to the wheel speed; taking the mileage data and a maximum value in original mileage data stored as actual mileage data to store and display; when a mileage reset request is received, if a reset flag bit is invalid, and the actual mileage data is not greater than a threshold value, resetting the actual mileage data. The invention further provides a mileage display system. According to the mileage display control method and system provided by the invention, the mileage data and the maximum value in the original mileage data stored are taken as the actual mileage data to be stored and displayed, and only when the mileage reset request is received, if the reset flag bit is invalid; the actual mileage data is not greater than the threshold value, the actual mileage data is reset; when the reset flag bit is valid or the actual mileage data is greater than the threshold value, the reset limit is performed, so that the accuracy is high.

Description

technical field [0001] The invention relates to the technical field of vehicle display control, in particular to a mileage display control method and system. Background technique [0002] Vehicle mileage represents the usage of the vehicle, which involves the interests of vehicle manufacturers, dealers, and customers, and is specifically reflected in the sales, maintenance, and value estimation of the vehicle. [0003] The existing vehicle mileage display control method is generally completed by the instrument and the engine control module, wherein the instrument and the engine control module calculate and store the accumulated mileage respectively, the accumulated mileage calculated by the instrument is used for display, and the accumulated mileage calculated by the engine control module is used for storage. backup. [0004] However, when the accumulative mileage calculated by the instrument and the engine control module is inconsistent, for example, due to the replacement...
