Embodiment Construction

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] figure 1The topology diagram of the vehicle network is shown. The vehicle network includes a power controller area network (PT-CAN) and a body controller area network (Body-CAN), which are isolated by a gateway (GW) route in the middle. PT-CAN includes engine management system (EMS), transmission control unit (TCU), electric power steering (EPS), airbag (ACM) and anti-lock braking system (ABS). , EPS, ACM, ABS and one end of G...

Abstract

The present invention provides a method for recording the total mileage of vehicles. The method comprises the following steps: calculating the mileage data by an anti-lock braking system, storing the data in two electric control units including the anti-lock braking system and an instrument, describing in details how the anti-lock braking system and the instrument store and synchronize the mileage data information and a fault handling mechanism, and simultaneously providing a flashing mechanism of the mileage data for after-sales repair. When the instrument is in fault, the anti-lock braking system can be used for calculating and counting the mileage data, the mileage data can be normally recorded and cannot be lost; the mileage data in the instrument can be prevented from being optionally flashed, and the authenticity and reliability of the mileage data can be ensured.

Description

technical field [0001] The invention relates to the technical field of automobile electronic control, and relates to a method for recording total mileage of automobiles based on automobile network communication, diagnosis and storage technologies. Background technique [0002] The total mileage of a car is the total number of kilometers traveled since the date of the vehicle leaving the factory. It is required to be recorded and displayed on the instrument, and it is a very important vehicle state parameter for users and maintenance personnel to understand the state of the vehicle. However, according to the traditional definition, if the total mileage data is only recorded in the meter, once the meter fails, the total mileage data will not be restored; in addition, due to economic interests, the used car sellers who lower the odometer reading and increase the price are not Individual, and it is very difficult for ordinary consumers to identify the odometer that has modified ...
