Embodiment Construction

[0036] The technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.

[0037] The invention provides an idle speed monitoring method based on the data of the Internet of Vehicles, such as figure 1 As shown, the idle speed monitoring method includes the following steps:

[0038] Step 1. Collect the driving data of the vehicle from the start of the new car to the preset mileage from the Internet of Vehicles, and obtain the normal range of the idling speed of the vehicle according to the driving data;

[0039] Step 2. Collect the driving data of the vehicle after the preset mileage from the Internet of Vehicles, and determine whether the idling speed of the vehicle is within the normal range according to the driving data after the preset mileage;

[0040] Step 3. When it is determined that the idling speed of the vehicle is not within the normal range, sequentially detect whether the parameters related to the ...

Abstract

The invention discloses an idle speed monitoring method based on data of the internet of vehicles. The idle speed monitoring method comprises the following steps of (1) collecting driving data of a vehicle from the beginning of the new vehicle to the preset driving mileage from the internet of vehicles, and obtaining a normal range of the idle speed of the vehicle according to the driving data; (2) collecting driving data of the vehicle after the preset driving mileage from the internet of vehicles, and judging whether the idle speed of the vehicle is within the normal range according to the following driving data; and (3) detecting whether relevant parameters of the idle speed of the vehicle are normal in sequence if the idle speed of the vehicle is not within the normal range, and finding faulty parts of the vehicle according to detection results. According to the idle speed monitoring method, whether the idle speed of the vehicle is normal can be monitored in real time, and the failure of the idle speed of the vehicle can be identified and diagnosed.

Description

Technical field [0001] The invention relates to the technical field of vehicle idle speed monitoring, in particular to an idle speed monitoring method based on vehicle networking data. Background technique [0002] Engine idle speed failure is a common vehicle failure. The existing analysis and diagnosis methods mainly include the following: 1. Ask the owner: learn from the owner ① the earliest time when idling instability appears; ② the engine temperature when idling instability; ③The mileage of the vehicle; ④The roads and habits that the owner often drives; ⑤The maintenance of the vehicle; ⑥The repair history of the vehicle; ⑦Whether the vehicle is equipped with equipment, etc., through the above understanding, make a preliminary judgment on idling instability; 2. Appearance Check: Open the engine hood, observe the engine operation and the degree of jitter, and observe whether the swing range of the engine tachometer pointer deviates from the expected idle speed, and whether it...
