Testing Device of Vehicle Pedal Control
Mechanism’s Performance Based on Virtual Instruments
Abstract
Virtual Instruments(VI) technology is nowadays a significant
direction of research and application in the field of measurement and
control. Testing of many parameters gradually speed-up, intelligent,
integrated evolvement already es a certain trend. In order to raise
efficiency and reduce the cost of testing the opening design ideology of
VI offers effectual way and method. The application of VI in the pedal
control mechanism testing is studied in this article, which includes
systematic architecture, software and hardware construction and
development of the program.
Through an overall analysis of the system, the systematic
architecture, hardware construction and software have been explained
separately in the paper. In this article set up a testing system of pedal
control mechanism and design a relevant integration testing device for
contact testing.
The hardware of testing system adopts pedal control mechanism
testing device developed by shanghai Jiaotong University, which is a
practicable and patented technology in testing field, integrates itself with
