Embodiment Construction
[0032] The core idea of the present invention is to provide a method for reminding vehicle maintenance, including:
[0033] Obtain the running state of the engine, and judge whether the running state of the engine is a normal running state; if so, obtain the sum of the combustion work of the engine within a period of time under the normal running state, and judge the sum of the combustion work of the engine Whether it is greater than or equal to the preset threshold, if so, remind the vehicle maintenance.
[0034] The method for reminding vehicle maintenance proposed by the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. And according to the following description, the advantages and features of the present invention will be more clear.
[0035] It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist t...

The present invention provides a method for reminding vehicle maintenance, by obtaining the sum of the combustion work of the engine during a period of time when the engine is running normally, and comparing the sum of the engine combustion work with a preset threshold, if the sum of the engine combustion work is greater than or is equal to the preset threshold, a vehicle maintenance reminder is triggered. Since the instantaneous power of the engine can better reflect the real-time working intensity of the engine, the sum of the combustion work of the engine during a period of time under normal operating conditions reflects the working intensity of the engine during this period, and then reflects the engine oil and other components Therefore, the invention can accurately reflect the maintenance timing of the engine, improves the accuracy and reliability of vehicle maintenance reminders, and has the advantages of low modification difficulty and low cost, simple design, convenient implementation, and reliable operation.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a method for reminding vehicle maintenance. Background technique [0002] For cars with a single internal combustion engine as the power source, the engine maintenance light is generally controlled by simply identifying whether the mileage has reached a preset value (such as 5000km). However, due to the diverse working modes of the gasoline-electric hybrid vehicle, it is difficult to simply judge the working intensity of the engine within the preset mileage, so the traditional control strategy of the engine maintenance light is no longer applicable. [0003] Currently, there are several control methods for the engine maintenance light of hybrid vehicles. Specifically, whether one of the mileage, total fuel consumption, and total number of engine cycles during engine operation reaches a preset value is used to determine whether it is necessary to remind the vehicle maintenance...
