Abstract:

At the present time automotive test data relative to use and operational environment is gathered by tachographs, analog tape recorders, and pulse code modulation PCM encoders. This project was to develop a Vehicle Performance Recorder VPR to augment the existing automotive test capability. The design objectives of the VPR were self-contained, analog and digital inputs, digital recording, programmable, not require an on site or skilled operator, 8-hour capacity, 0.1 analog accuracy, 30-second time resolution, useable in US Army Aberdeen Proving Ground APG environment, 28 VDC operation, and internal battery operation. A unit which meets these objectives is described in detail. The VPR uses a commercial cassette recorder and a custom controller to provide a flexible, low-power consumption data acquisition system. A description of alternative systems is also provided. It is concluded that a the VPR satisfies a wide variety of measurement needs b commercially manufactured units now exist with a wide spectrum of capabilities c the Army developed Vehicle Monitoring System VMS may be available in the future d no single unit satisfies all possible data acquisition requirements. It is recommended that a commercially available unit be used if possible if not then the VPR be used. Author
