Abstract

The invention discloses a hardware-in-loop (HIL) testing platform of a velocity measuring system (VMS). The HIL testing platform comprises an acquisition board, a fault board, a load board, multiple sensors and a dspace main controller; the acquisition board is in communication connection with the VMS, and is used for conditioning an input signal and an output signal of the VMS and monitoring waveforms; the fault board is used for providing a fault injection to the VMS and for testing a protecting function after the fault; the load board is used for providing a load to the VMS; the multiple sensors are in communiation connection with the load board and are used for acquiring signals which are required by multiple VMSs; the dspace main controller is in communication connection with the VMS as well as the fault board and the load board, and is at least used for controlling communication, signal acquisition, signal generation, board control, vehicle model operation and testing model operation. With the additional arrangement of the fault board as well as the structure designs which are independent in function, the testing platform is convenient to built, recombine, debug and maintain; and meanwhile, the structure of the system is very simple.

Description

technical field [0001] The present invention relates to a test device suitable for a Vehicle Management System (VMS for short) of a new energy vehicle, in particular to a hardware-in-the-loop (HIL for short) test bench for a VMS. Background technique [0002] New energy technology is the development direction of automobile technology. As a new energy vehicle vehicle controller system, VMS is one of the three core technologies of new energy vehicles. It has become a hot spot in new energy technology research. The quality of VMS system design is related to the performance and safety of the vehicle. In the process of VMS system development, testing and release, the necessary HIL test bench is a key equipment. However, the current HIL test bench has a single function and is only customized according to a specific Electronic Control Unit (ECU for short), lacking versatility. Contents of the invention [0003] The purpose of the present invention is to provide a VMS HIL test b...
