Mobility Monitoring System and Vehicle Performance Recorder.

Abstract : This report investigates, to determine information gathering techniques for the Vehicle Performance Recorder. Vehicle endurance testing is typically controlled (formally) only to the extent that a target number of miles and a pedagogical mix of terrain types (mission profile) are established. This situation leads to ambiguities in relation to test severity, and leaves open the possibility of overstressing (bad for suppliers) or understressing (bad for Government) of test vehicle. This report covers the development of methodology that centers on the Vehicle Performance Recorder (VPR) (a small, self contained microcomputer based data acquisition and processing system) to collect and process data during endurance testing. The data so collected provides immediate information for test control, and is entered into an overall data base for historial, trend, and other analyses. The implementation and application of this methodology to the Initial Production Test and Follow-on Evaluation of the High Mobility Multipurpose Wheeled Vehicle (HMMWV) is briefly covered.
