Embodiment 1

[0028] see figure 1 , figure 2 , the vehicle-mounted terminal software real-vehicle test method of the present invention, adopts CAN transceiver equipment, test computer and host computer to build a test platform, connects CAN transceiver equipment to vehicle OBD port, reads vehicle CAN signal, and the other end connects test computer, transmits signal Go to the test computer for analysis; connect the relevant equipment, turn on the host computer, import the test signal list, and click to start the test. Described vehicle-mounted terminal software testing method comprises the steps:

[0029] S1, prepare the vehicle to be tested, update the vehicle terminal software installed on the vehicle to the software version to be tested, and ensure that the vehicle has been connected to the platform;

[0030] S2, start the test host computer, import the signal list of the vehicle model to be tested, and start the vehicle;

[0031] S3, input the VIN code of the waiting vehicle on the ...

Embodiment 2

[0035] The vehicle-mounted terminal software actual vehicle test method described in this embodiment differs from Embodiment 1 in that: further, in step S1, first write the VIN code of the test vehicle to the vehicle-mounted terminal to be tested, and derive the ICCID of the vehicle-mounted terminal , IMEI and other information; register the VIN code of the vehicle to be tested and the information of the corresponding vehicle terminal to the platform.

Embodiment 3

[0037] see figure 1 , is the frame diagram of the real vehicle test system of the vehicle terminal software of the present invention. The vehicle-mounted terminal software real vehicle test system includes a vehicle-mounted CAN signal transceiver device, a test computer and a host computer, and the vehicle-mounted CAN signal transceiver device, during the test process, one end is connected to the OBD port of the car to receive CAN bus data, and one end is connected to the test The computer and the upper computer receive the control of the upper computer; the on-board CAN signal transceiver equipment: mainly used to read and simulate the data sent by each module of the vehicle to the CAN bus;

[0038] The test computer and upper computer are mainly used to import the test signal list, read the CAN bus data and the data value reported by the vehicle terminal in the test platform, compare the consistency of the CAN bus data and the data reported by the vehicle terminal platform a...

Abstract

The invention discloses a vehicle-mounted terminal software real vehicle testing method and system. The vehicle-mounted terminal software real vehicle testing method comprises the steps: adopting a CAN transceiver, a testing computer and an upper computer to build a testing platform, updating the vehicle-mounted terminal software mounted on a vehicle to a to-be-tested software version, and ensuring that the vehicle is connected with an upper platform; starting a test upper computer, importing a to-be-tested vehicle model signal list, and starting the vehicle; inputting a VIN code of a to-be-tested vehicle into an interface of the testing upper computer, and clicking to start testing; enabling the test upper computer to read CAN bus data and a data value reported by the vehicle-mounted terminal in the testing platform, and comparing the consistency of the CAN bus data and the data reported by the vehicle-mounted terminal to the platform after data analysis; and outputting a test report after the test. A vehicle-mounted terminal software real vehicle test system comprises the vehicle-mounted CAN signal transceiver, the test computer and the upper computer, one end of the vehicle-mounted CAN signal transceiver is connected with an automobile OBD port to receive the CAN bus data in the test process, and the other end of the vehicle-mounted CAN signal transceiver is connected with the test computer and the upper computer.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and system for actual vehicle testing and bench testing of vehicle-mounted terminal software. Background technique [0002] According to the relevant requirements of GB32960 and GB17691, all new energy and heavy-duty diesel vehicles must install vehicle-mounted terminals to report vehicle-related data and vehicle fault signals in real time, coupled with the continuous promotion of intelligent networked vehicles, more and more commercial vehicles and passenger vehicles Vehicle terminals will be installed. Whether the terminal software is developed according to the requirements is particularly important. [0003] In the software development process of vehicle-mounted terminals, in order to ensure the stability and correctness of data upload after mass production, it is generally necessary to go through multiple rounds of full-function tests to check the accuracy of ea...
