The vehicle is a very complex machine. Its efficiency is influenced not only by its mechanical sub-systems -- engine, transmission, etc. -- but also by the external environment and type of operation. Off-road attempts to characterize the vehicle can only accomplish limited results. Monitoring of the vehicle in actual on-road, in-service operation is necessary to obtain the information needed for judging the effects on fuel economy and operating costs. Rockwell International has installed its Tripmaster Instrumentation System on-board eight vehicles donated by the OEM's (Original Equipment Manufacturers). The systems provide the equipments and programmed instructions to gather these factors during in-service operation. The trucks have been placed with commercial fleets for use on their usual runs. Initial indications show that the system will gather the desired information.
