Embodiment 1

[0026] Example 1: as figure 1 Shown, the present invention is a kind of automobile mileage calculation method, comprises the following steps:

[0027] During the running-in period of the vehicle, the equivalent mileage is equal to the rolling mileage of the wheels along the road surface. After the running-in period, the process starts from step 101;

[0028] Step 101, set the stage road section Li step length, set to 1 kilometer in this embodiment, the equivalent mileage is calculated once every 1 kilometer, and it is also accumulated once per 1 kilometer when the equivalent mileage is accumulated; Acquisition of vibration acceleration on a 1 km road section on a standard road surface;

[0029] Step 102, separating the collected vibration acceleration signals, filtering out engine vibration interference, and separating road surface driving vibration acceleration;

[0030] Step 103, calculate the root mean square value of the vibration acceleration a0, store it as a standard ...

Embodiment 2

[0036] Embodiment 2: as figure 2 Shown, a kind of vehicle mileage calculating device comprises a vehicle speed sensor 2, a microprocessor 4, a vibration acceleration sensor 1, a mileage calculation module, and the output of the vibration acceleration sensor 1 is connected to the microprocessor 4 for measuring the vibration acceleration of the vehicle, The vehicle speed sensor 2 is connected to the microprocessor 4 for measuring the rolling mileage of the wheels along the ground; the mileage calculation module is installed in the microprocessor 4, due to the calculation of the equivalent driving mileage, the rolling mileage of the wheels along the road surface; the signal separation unit is installed in the microprocessor In 4, it is used to filter out the engine vibration interference and separate the vibration acceleration, the keyboard 3 is used for parameter setting input, and the display 5 is used for displaying the cumulative mileage of the equivalent driving and the cumu...

Abstract

The invention discloses a calculating method and device for trip distance of a car, and aims to solve the problem of the prior art that the a vehicle is just maintained based on the trip distance of the vehicle running along the ground and without consideration on the influence of running under poor road condition on the service life of the vehicle. According to the method and device disclosed by the invention, the influence of the bumpy pavement on the service life of the vehicle is fully taken into account during calculating the equivalent trip distance. The method comprises the steps as follows: the trip distance of the vehicle is taken as the trip distance of wheels running around the pavement when the vehicle is in a running-in period; the equivalent trip distance can be referred to be expressions in the specifications, and the total equivalent trip distance refers to the expression in the specifications; the equivalent trip distance, and the trip distance of the wheels running along the pavement, etc. are added up.

Description

technical field [0001] The invention relates to a calculation of the driving mileage of an automobile, in particular to an equivalent mileage calculation method and a corresponding device which consider factors affecting the service life of the automobile due to road bumps. Background technique [0002] The service life of a car is closely related to the driving mileage. Currently, the driving mileage of a car is generally only calculated for the actual mileage of the vehicle, that is, the mileage of the wheels rolling along the ground. However, the service life of the vehicle is closely related to the driving conditions of the vehicle. When the vehicle is damaged When driving on the road, the mileage of the vehicle is basically the same as that on a good road. However, as we all know, driving on a bad road will reduce the service life of the car, and the reliability of the car is far from that on a good road. Therefore, the maintenance time of the vehicle should not only re...
