This paper reports on the preliminary results of a research effort being performed for the Department of Energy to investigate and evaluate methods of providing feedback to automobile drivers during vehicle operation which will help to promote fuel conservation. Popular so called “trip computers” and other fuel conservation devices are evaluated in the laboratory and on the highway. System concepts are developed to provide visual and auditory feedback to the operator utilizing appropriate locations for additional on-board displays. A variety of feedback devices are installed in a test vehicle for evaluation of user preference and the effectiveness of the device in promoting fuel conservation.
