Abstract

The application relates to a vehicle automatic test system, test method and device. The vehicle automatic test system comprises a powertrain controller and a computer device for running test software,and comprises a fault injection and repair device, and calibration hardware. The powertrain controller connects an entire vehicle wiring harness through the fault injection and repair device, and connects the computer device through the calibration hardware. The computer device is connected to the fault injection and repair device. The computer device runs the test software to transmit a controlcommand to the fault injection and repair device. The fault injection and repair device performs fault injection based on the control command. The computer device performs diagnostic communication ofthe injection fault through the calibration hardware and the powertrain controller. The powertrain controller detects and repairs the injection fault based on the entire vehicle wiring harness. According to the vehicle automatic test system, test method and device, the test time can be effectively saved, the work of the test design process can be reduced, and the repeatability and consistency of afault diagnosis module test of the production vehicles can be improved.

Description

technical field [0001] The present application relates to the technical field of vehicle testing, in particular to a vehicle automatic testing system, testing method and device. Background technique [0002] With the emission regulations of road vehicles becoming more and more stringent, especially after the implementation of the national sixth-stage emission regulations, vehicle manufacturers need to diagnose the fault diagnosis module of the vehicle powertrain controller (hereinafter referred to as OBD system; OBD: On- Board Diagnostic, that is, on-board diagnostic system) conducts self-inspection of production consistency (COP: Conformity of Production, motor vehicle product production consistency). After the vehicle is officially mass-produced, the vehicle manufacturer needs to submit the corresponding test plan and report. And accept the supervision and inspection of relevant agencies. [0003] However, during the implementation process, the inventors found that there ...
