    Abstract
  • A test system of automotive electrical acceleration pedal was designed based on non-contact angle replacement sensor and the output characteristics of idle switch due to stampeding speeds and sampling frequencies. With ADLink-PCI911DG acquisition card, PCI-DAQ virtual instrument technology and LabVIEW software, the angle sensor signal was transferred by A/D, was driven by DAQ, and the data acquisition was realized automatically. The key factors that affected the switch signal of electrical acceleration pedal were analyzed under fast press and fast release, fast press and slow release, slow press and fast release, slow press and slow release.The result shows that the speeds and frequencies are main influence factors, and the sampling frequencies are not less than 1 000 Hz to ensure measuring precision. The measuring errors are minimal under slow press and slow release, and the errors are maximal under fast press and fast release. Based on the result, some error reasons and solving measures are proposed.
