An algorithm for identifying illegal refueling behavior of heavy trucks

Abstract

The present invention relates to an identification algorithm for illegal refueling of heavy trucks, which solves the problem that the current method cannot respond immediately and identify illegal refueling. The specific steps are: 1) judging the vehicle reporting information, if the vehicle is in a flameout state, the vehicle speed is 0, that is, the vehicle is flameout and parked, and the fuel tank level at this time is recorded as L1, time S1 and the latitude and longitude of the vehicle at this time; 2) when the vehicle is powered on again and the speed is not 0, record the current fuel tank level L2 and time S2, and judge whether the oil level before and after power-on has increased significantly, that is, if there is a significant increase, record the difference in oil volume increase; 3) when the oil volume difference and the parking time meet a certain relationship, it is recorded as a refueling stop: 4) query whether there is a gas station within the three decimal places of latitude and longitude through reverse geocoding of the map; 5) if there is a gas station, it is judged as a refueling stop, and if there is no gas station, it is identified as an illegal refueling. The method of the present invention can reduce the quality assurance pressure of automobile companies and reduce the cost of manual management.

Description

Technical Field

[0001] The invention relates to an algorithm, and in particular to an algorithm for identifying illegal refueling behavior of heavy trucks. Background Art

[0002] With the development of science and technology and the guidance of national policies, the development of vehicle interconnection has been rapidly improved. After the trial operation of the National VI emission standard for commercial vehicles, under the title of global carbon neutrality, the public has paid more attention to the carbon emissions of vehicles; and in the operation mode of commercial vehicle owners-drivers, in order to prevent drivers from "adding less oil" and "adding bad oil" and other behaviors that damage the vehicle and evade vehicle supervision, there are currently some algorithms on the market that use emission monitoring to reverse the addition of low-quality oil to assist managers in identification. However, this identification method is delayed, and the vehicle has already accumulated carbon when it is discovered, which puts great pressure on the environment. Summary of the invention

[0003] In view of the current situation that it is impossible to respond immediately and identify illegal refueling, the present invention develops a complete set of fast, accurate and convenient methods for judging illegal refueling behavior of heavy trucks, which assists management personnel in judging vehicle violations, improves vehicle management efficiency, saves costs and creates value.

[0004] The present invention is achieved by the following technical solutions:

[0005] An algorithm for identifying illegal refueling behavior of heavy trucks is designed. For electronically controlled engines, the intelligent vehicle terminal installed on the heavy vehicle collects the vehicle's position, engine speed, and fuel tank level information in real time. The Internet of Vehicles platform calculates the illegal refueling behavior of the vehicle by judging the vehicle information based on the cloud computing path. The specific steps are as follows:

[0006] 1) Determine the vehicle's reported information. If the vehicle is in a stalled state and the vehicle speed is 0, the vehicle is stalled and parked. Record the fuel tank level at this time as L1, the time S1, and the latitude and longitude of the vehicle at this time;

[0007] 2) When the vehicle is powered on again and the speed is not 0, record the current fuel tank level L2 and time S2 to determine whether the fuel level has increased significantly before and after power-on. If so, record the difference in fuel level increase;

[0008] 3) When the difference in fuel volume and the parking duration have the following relationship, it is recorded as a refueling stop:

[0009] 200L≦L2-L1<300L and S2-S1>4min;

[0010] 300L≦L2-L1<400L and S2-S1>6min;

[0011] 400L≦L2-L1<500L and S2-S1>8min;

[0012] L2-L1≧500L and S2-S1>10min;

[0013] 4) Use reverse geocoding on the map to check whether there is a gas station within three decimal places of latitude and longitude;

[0014] 5) If there is a gas station, it is judged as a stop for refueling. If there is no gas station, it is identified as an illegal refueling.

[0015] The method of the present invention can assist in analyzing the refueling status, help to prevent drivers from refueling illegally, extend the service life of the vehicle, reduce the quality assurance pressure of the car companies, and reduce the labor management costs. DETAILED DESCRIPTION

[0016] The present invention targets electronically controlled engines and collects vehicle location, engine speed, and fuel tank level information in real time through an intelligent vehicle-mounted terminal installed on a heavy-duty vehicle. The Internet of Vehicles platform calculates the vehicle's illegal refueling behavior by judging the vehicle information based on the cloud computing path:

[0017] 1. Determine the vehicle reporting information. If the vehicle is in the off state and the vehicle speed is 0, the vehicle is off and parked. Record the fuel tank level at this time as L1, time S1 and the latitude and longitude of the vehicle at this time.

[0018] 2. When the vehicle is powered on again and the speed is not 0, record the current fuel tank level L2 and time S2 to determine whether the fuel level has increased significantly before and after power-on, that is, L2-L1. If there is a significant increase, record the difference in fuel increase.

[0019] 3. When the difference in fuel volume and the parking time have the following relationship, it is recorded as a refueling stop

[0020] Oil volume difference (L2-L1) Duration (S2-S1) 200L More than 4 minutes 300L More than 6 minutes 400L More than 8 minutes 500L More than 10 minutes

[0021] 4. Use reverse geocoding on the map to check whether there is a gas station within three decimal places of longitude and latitude.

[0022] 5. If there is a gas station, it is considered a stop for refueling. If there is no gas station, it is identified as an illegal refueling.

[0023] The present invention uses a vehicle networking platform based on a Beidou vehicle terminal to first obtain information such as the vehicle location, and then judge the parking status of the vehicle through a parking algorithm. Secondly, Baidu service is used to judge whether there are gas stations around the vehicle, and then the illegal refueling operation of the vehicle is judged. The efficiency of vehicle management personnel in judging the parking of vehicles is improved, and illegal behaviors can be traced, which reduces management costs, extends the service life of vehicles, and improves the accuracy of judgment.
