Abstract

The invention relates to the technical field of vehicle brake control, and discloses a commercial vehicle electronic parking system controller hardware-in-the-loop test device and method. The device comprises an air brake test bench, an EPB controller, a computer, IPG / Xpack 4 real-time hardware and a programmable power supply, and can simulate a real test scene. Driver operation, road environment, real vehicle operation conditions and the like are restored to the maximum extent, various function tests can be conveniently carried out on the EPB controller, various limitations possibly encountered in the real vehicle test process are reduced, the development cost is reduced, the development period is shortened, and the device has the advantages of being high in test efficiency, wide in test coverage and real-time and visible in test result.

Description

technical field [0001] The invention relates to the technical field of automobile braking control, in particular to a hardware-in-the-loop testing device and method for a commercial vehicle electronic parking system controller. Background technique [0002] The hardware-in-the-loop test system (Hardware-in-the-Loop) uses a real-time processor to run a simulation model to simulate the running state of the controlled object, connects with the controller under test through the I / O interface, and performs a test on the controller system under test. Functional and performance testing. The traditional test method adopts the real vehicle test. Due to the need to realize various complex working conditions of the vehicle, higher requirements are placed on the driver's operating level and working condition design, which greatly increases the difficulty of testing and the development cycle. In addition to the test risk, the consistency of the test cannot be guaranteed. The control st...
