Body electronic control system test platform based on hardware-in-the-loop

Abstract

The invention discloses a testing platform for a vehicle body electronic control system based on hardware-in-the-loop, which includes a host computer (1), a testing cabinet (2), a movable terminal block (3) and a laboratory car bench (4); the testing cabinet It is composed of multiple modules, and the movable terminal block is used to connect the test cabinet, the controller to be tested and the laboratory car bench. The laboratory car bench is used to build the vehicle body switch and real load; The PXI real-time controller in the cabinet is connected to monitor the operation of the test platform in real time; the cabinet power input module of the test cabinet is connected to an external power supply to realize the power distribution and system protection of the cabinet power supply; the movable terminal block is connected to the test cabinet through the cabinet panel connector, through The wiring harness is connected with the laboratory car bench and the controller to be tested, which can simulate the excitation signal of the controller to be tested; the controller fault injection module can simulate short-circuit to ground, short-circuit to power, and open-circuit faults to test the fault diagnosis function of the controller .

Description

technical field [0001] The present invention relates to a test device and method for an automobile electrical system, in particular to an electronic control system for verifying a vehicle body, including a keyless entry controller (PEPS), a body controller (BCM), an adaptive headlight Hardware-in-the-loop (HIL) test platform for the four body ECUs of the regulator controller (AFS) and instrumentation (IPK). Background technique [0002] Due to the increasingly complex automotive electrical systems, in the development process of new models, it is necessary to conduct functional tests, performance tests and diagnostic tests on the body electrical control system to ensure the reliability and stability of the body electrical systems. At present, most of the automotive electronic product testing is to build a test environment through a manual bench, which has low reusability and is difficult to simulate extreme or dynamic conditions. It is highly dependent on testers and low in t...

At present, most of the automotive electronic product testing is to build a test environment through a manual bench, which has low reusability and is difficult to simulate extreme or dynamic conditions. It is highly dependent on testers and has low test efficiency; some automated equipment can only test A single automotive electronic controller cannot be tested for integration, or can only simulate a static environment and cannot be tested dynamically
