Embodiment 1

[0052] refer to figure 2 ,

[0053] A method for supervising the use of test vehicles, including the following methods:

[0054] Step 1. After the vehicle is first powered on or awakened, the data collection and uploading device 1 collects the vehicle condition signal 9 of the test vehicle, and collects the CAN signal corresponding to the CAN channel in real time.

[0055] After the vehicle is first powered on or woken up, the data collection and uploading device 1 sends a diagnostic command to read the vehicle code to obtain the serial number of the test vehicle and store it in the data collection and uploading device 1 .

[0056] The vehicle condition signal includes power supply status signal, battery SOC value, battery voltage, four door status signals, four window status signals, sunroof status signal, near light status signal, high beam status signal, vehicle speed signal, rotational speed signal, Engine status signal, brake switch signal, gear signal, fuel level / powe...

Embodiment 2

[0074] refer to figure 1 , a system for supervising the use of test vehicles, comprising: a data collection and uploading device 1, a gateway 2, ECUs 3, a server 4, a test vehicle monitoring system 5, a test vehicle borrowing system 6, a project management system 7 and a storage battery 8.

[0075] Described data acquisition and upload equipment 1 are connected with gateway 2 by CAN bus; Described gateway 2 is connected with ECUs3 by CAN bus; Described storage battery 8 is connected with data acquisition and upload equipment 1, gateway 2 and ECUs3; Described data acquisition and The uploading device 1 is connected to the data collection and uploading device 1 through the 4G Internet access module; the test vehicle monitoring system 5 obtains the information of the data collection and uploading device 1, the test vehicle borrowing system 6 and the project management system 7, and builds it through the server 4.

[0076] The data collection and uploading device 1 is used for col...

Embodiment 3

[0112] The present invention analyzes the use of a certain pure electric vehicle, calculates the total use time of the vehicle, the daily average use time, the cumulative mileage, and the number of charging times based on the vehicle’s network access time and statistical analysis model, and conducts an evaluation of the use of the vehicle. Multi-dimensional monitoring and input of supervision to projects. After checking with the vehicle borrower, the project redistributed the vehicles whose average daily usage time was less than 4 hours. The specific monitoring situation is shown in Table 3:

[0113]

[0114] To sum up, the present invention collects, uploads, stores, and analyzes and models the vehicle condition data of the test vehicle to realize functions such as test vehicle information query, use status monitoring, early warning of illegal vehicle use, and test item monitoring, and provides a basis for the planning of test vehicles. , approval, borrowing, and test pro...

Abstract

The invention relates to the technical field of automobiles, in particular to a test vehicle use supervision method and supervision system. The test vehicle use supervision system comprises a data acquisition and uploading device, a gateway, an ECU, a server, a test vehicle monitoring system, a test vehicle borrowing system, a project management system and a storage battery. According to the test vehicle use supervision method, the functions of test vehicle information inquiry, use state monitoring, illegal vehicle use early warning, test item monitoring and the like are achieved by collecting, uploading, storing and data analysis modeling of vehicle condition data of a test vehicle, and data support is provided for planning, approval, borrowing and test item execution conditions of the test vehicle. The system improves the circulation of test vehicles, enhances the supervision of test items, reduces the number of test vehicles in the whole vehicle development and verification stage, reduces the whole vehicle development cost, reduces the problem of flowing into the market, and improves the market praise of vehicles.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a test vehicle use supervision method and a supervision system. Background technique [0002] With the rapid development of the automobile industry, the launch speed, price and market reputation of a car company's new models are the foundation of a company's foothold. The cost of the test vehicle, the test period, and the test effect are the key factors affecting the speed, price and market reputation of the new model. Although many car companies have fully considered the needs of various majors when planning the number and configuration of test vehicles, each major generally submits the demand for test vehicles according to the longest cycle, so there will always be various problems in the actual use process. These factors cause some vehicles to be used beyond the expiry date, while some vehicles complete the verification in advance, and some problems that should be discove...
