Hardware-in-loop-based automation test system for automobile diagnosis, and method thereof

Abstract

The invention relates to a hardware-in-loop-based automation test system for automobile diagnosis, and a method thereof. The hardware-in-loop-based automation test system for automobile diagnosis comprises a gearbox ECU module, a complete vehicle test environment module, an automatic operation test task module and a measurement calibration tool which are connected successively to form a loop, wherein the gearbox ECU module sends a gearbox control command to the complete vehicle test environment module; the complete vehicle test environment module returns the simulation vehicle driving parameter information; the gearbox ECU module sends a communication signal for the complete vehicle and calibration to the measurement calibration tool; the measurement calibration tool returns a command for modifying calibration parameters; the automatic operation test task module sends a control command to the complete vehicle test environment module and the measurement calibration tool; and the complete vehicle test environment module and the measurement calibration tool send the simulation vehicle driving parameter information and the communication signal for the complete vehicle and calibration to the automatic operation test task module respectively. The hardware-in-loop-based automation test system for automobile diagnosis, and the method thereof can modify the calibration parameters and the complete vehicle environmental parameters under different conditions, and can perform diagnosis test, and has no need for manual intervention and is efficient and accurate.

Description

technical field [0001] The invention relates to a technology in the field of automobile diagnostic testing, in particular to a hardware-in-the-loop automatic testing system and method for automobile diagnosis. Background technique [0002] In recent years, with the improvement of people's requirements for energy saving, safety, and comfort of automobiles, automobile developers have proposed many new concepts to meet user needs and improve market competitiveness. In the research and development process of new products, the testing link is particularly important. Test quality directly reflects the performance and quality of developed products, and diagnostic tests play a vital role in automotive safety. The function of automobile diagnostic test after the vehicle is put into use is to detect whether there is a fault in the system and equipment and to further determine the fault. The function in the product development stage is to verify whether the fault occurs and the fault ...
