Abstract

The invention relates to a method, device and system for carrying out function detection on a hardware-in-loop HiL device. The HiL device comprises at least one function reciprocity module pair whichis connected through a wiring harness. The method comprises the following steps of generating a test signal aiming at a function of a first module in the module pair; inputting the test signal into the first module; acquiring an input signal of an input portion of a second module in the module pair; and detecting functional accuracy of the module pair based on the test signal and the input signal.In the invention, through a specific wiring harness design, a plate card of the HiL device is used to detect other plate cards, and through a corresponding detection method, each sub-function moduleof the HiL device is mutually inspected conveniently at a fixed period. A test result is accurate and reliable, a fault and an error can be conveniently found, and integral accuracy and stability of an HiL environment are effectively increased.

Description

technical field [0001] The present invention generally relates to the field of electronics, and specifically relates to a method, device and system for performing function detection on a hardware-in-the-loop device. Background technique [0002] Hardware-in-the-loop (HiL, Hardware in Loop) testing is widely used in the development of complete vehicles and their components. Through the HiL test, the function of a single component can be easily verified, and the interaction between different components can also be verified. In addition, for some tests that are very difficult or expensive in the real vehicle verification process, such as crash test, high temperature / low temperature test, etc., preliminary functional verification can be easily performed in the HiL environment, and the function can be matured and stabilized. Then the final real vehicle verification is carried out, so as to shorten the research and development time and save the research and development cost as mu...
