Problems solved by technology
[0005] ①. Uneconomical: Customers change oil in advance, resulting in increased maintenance costs;
[0006] ②. Not environmentally friendly: oil change in advance, resulting in more waste oil and increased pollution;
[0007] ③. Unsafe: If the maintenance is not timely, the oil will deteriorate and the engine will be damaged;
[0008] ④. Not precise: the oil change period is not determined according to different working conditions and fuel conditions;
[0009] ⑤. Unintelligent: Cannot carry out predictive maintenance, does not meet the requirements of intelligence

The invention discloses a method and system for on-line monitoring of vehicle engine oil, which relates to the field of automobile maintenance. The method includes acquiring fuel consumption per 100 kilometers, engine oil performance information and ECU data. The engine oil performance information includes engine oil viscosity information, total base number information, Total metal particle information as well as soot information. Calculate actual fuel consumption correction parameters and speed correction parameters according to the 100-kilometer fuel consumption and ECU data. Input the oil viscosity information, total base number information, total metal particle information and soot information into a preset prediction model to obtain the oil change time. According to the actual fuel consumption correction parameter and the speed correction parameter, the oil change time is corrected to obtain the oil change life. The invention can grasp the real-time performance parameters of the oil in time, and at the same time, combine with the vehicle condition, predict the oil consumption trend, and give the oil change time.
Description
technical field [0001] The invention relates to the field of automobile maintenance, in particular to a method and system for on-line monitoring of vehicle engine oil. Background technique [0002] In traditional car maintenance, the engine oil maintenance of the car is in accordance with the regulations of the car manufacturer, using fixed mileage or fixed time maintenance. This is actually a compromise method and cannot be 100% applicable to every car. Due to the different working conditions of vehicles, such as different fuel quality, different road conditions, different driving habits and many other factors, the oil deterioration speed of each vehicle is different. The current maintenance method based on mileage or driving time has certain defects. [0003] Carrying out unified maintenance on vehicles based on fixed mileage or fixed time can easily lead to vehicle engine damage due to insufficient maintenance, or high maintenance costs for users due to too frequent maint...
