New Automotive Sensors—A Review

Abstract

This paper focuses on the primary automotive sensor technologies used today and their related system applications. This paper describes new automotive sensors that measure position, pressure, torque, exhaust temperature, angular rate, engine oil quality, flexible fuel composition, long-range distance, short-range distance, and ambient gas concentrations. In addition, new features are described for sensors that measure linear acceleration, exhaust oxygen, comfort/convenience factors, and night vision. New automotive system applications are described for sensors that measure speed/timing, mass air flow, and occupant safety/security.
