AI Technical Summary

Technical Problem

In the existing technology, the calculation method for vehicle oil life fails to take into account the impact of the actual operating conditions of the vehicle, resulting in inaccurate calculations, failure to change the oil in a timely manner, and affecting engine performance.

Method used

By acquiring engine speed and running time, and combining parameters such as ambient temperature, load, and water temperature, a correction factor is used to correct the engine running time, and the remaining oil life is calculated, thus providing a method and device for calculating vehicle oil life.

Benefits of technology

It improves the accuracy of oil life calculation, reduces errors, ensures that the oil is changed in time before the maintenance cycle is reached, and avoids the impact of degraded oil performance on the engine.

Abstract

The application belongs to the technical field of engine control, and particularly relates to a vehicle engine oil life calculation method and device, readable medium and electronic equipment. The method comprises the following steps: obtaining an engine speed and an engine running time cumulative value of a vehicle; determining the engine running time cumulative value according to the engine speed; adding the engine running time cumulative value and the engine running time cumulative value to obtain an updated engine running time cumulative value; and calculating a remaining engine oil life of the vehicle according to the updated engine running time cumulative value and a total life time corresponding to vehicle engine oil. In this way, compared with a scheme of determining the remaining engine oil life only by the engine running time, the application combines the influence of real-time working conditions on the engine oil life, corrects the total engine running time by calculating the engine running time cumulative value, improves the accuracy when calculating the remaining engine oil life, and thus reduces the error with the actual engine oil life.
