The pulse signal DAQ instrument is developed for testing motor vehicle performance.A full range sampling timer is designed and installed in a data acquisition circuit so as to make a real-time determination of the pulse group and pulse number per sampling according to the requirement for the sampling accuracy and rate,thus eliminating the influence of the serial communication rate limit and its transfer time delay on the data processing accuracy.The real motor vehicle road tests show the design of the DAQ instrument is practical and effective.
