Abstract

The invention discloses a method to count the vehicle running mileage which relates to a method to count the vehicle running mileage by using the GPS receiving module and computer. It can solve the problem that the odometer stopwatch number can be adjusted by hand to loss facticity. The invention includes the GPS module receives the vehicle position information at fixed time interval, the distance between two near vehicles can be get by computing the latitude and longitude; computing the rectify distance of running distance between two near vehicles by using the rectify coefficient; overlapping the above rectify distance to the accumulative running mileage data; the accumulative running mileage is stored in the nonvolatile memory. It can protect the mileage data not loss after cutting electricity and to be juggled by human. The accumulative running mileage data is added with the check code to store. It is convenience to resume the accumulative data after restoration or giving electricity to improve reliability and confidentiality of data.

Description

technical field [0001] The invention relates to a method for counting vehicle mileage by using a GPS receiving module and a computer. Background technique [0002] Vehicle accumulative mileage data is an important part for estimating vehicle condition data, especially when dealing with old cars, accumulative mileage data is an important factor. Most vehicles have a mechanical odometer that is used to measure the number of revolutions of the wheels, and convert the cumulative mileage accordingly. The digital dial of the odometer is installed on the instrument panel in the car to display the value of the cumulative mileage. In recent years, an electronic odometer equipped with a speed / mileage sensor has been installed on a vehicle to measure and display accumulated mileage data. However, this electronic odometer is the same as the mechanical odometer. The mechanical digital dial displaying the accumulated mileage value is installed on the instrument panel in the car. , so th...
