Complete configuration vehicle machine, T-BOX testing device and T-BOX testing method

Abstract

The invention discloses a complete configuration vehicle machine and T-BOX test device, which is a CAN analog machine and comprises a machine box; a SD card module, a IO module, an AD conversion module and a CAN communication module. The SD card module, the IO module, the AD conversion module and the CAN communication module are arranged in the machine box. The device also comprises a central processing unit arranged in the machine box and connected with the SD card module, the IO module, the AD conversion module and the CAN communication module. The invention further discloses a test methodof the complete configuration vehicle machine and the T-BOX test device. According to the invention, a mode of a CAN configuration file and a CAN description file is adopted, a key signal, a single-selection switch, a rotary encoder and a CAN signal are changed into configuration variables, and the sending condition of a CAN frame and the signal value of the CAN are flexibly configured, so that almost any CAN message can be simulated, and customized development on software is not needed.

Description

technical field [0001] The invention relates to the technical field of electric vehicle testing, in particular to a fully configured vehicle machine and T-BOX testing device and a testing method thereof. Background technique [0002] The car machine and T-BOX (telematics processor) need to conduct a lot of tests in the R & D verification and mass production test stages. These devices often only communicate with the vehicle through the CAN bus. During the test process, it is necessary to simulate various conditions and / or T-BOX to send different CAN messages, and observe whether the tested vehicle and / or T-BOX responds correctly. At present, most of the car machine and T-BOX test systems on the market adopt the mode of matching the control box and the upper computer, and carry out customized development of software and hardware according to the needs of each product developer. The disadvantage of this model is that it needs to be redeveloped every time a product is replaced,...

Problems solved by technology

The disadvantage of this model is that every time a product is replaced, it needs to be redeveloped, the development cycle is long, and the versatility is poor

In addition, this mode also needs to be equipped with a host computer, which is costly and bulky

At the same time, it also requires high programming ability, which undoubtedly increases the difficulty of testing.
