Overview of automotive sensors

TLDR

The field of automotive sensors is extensive, encompassing dozens of sensor types across powertrain, chassis, body, and emerging technologies. This review focuses on sensors employed in production automotive systems, presenting an up‑to‑date overview. The paper catalogs six rotational motion, four pressure, five position, and three temperature sensor types used in automotive systems. Primary sensor technologies are classified into powertrain, chassis, and body application areas.

Abstract

An up-to-date review paper on automotive sensors is presented. Attention is focused on sensors used in production automotive systems. The primary sensor technologies in use today are reviewed and are classified according to their three major areas of automotive systems application-powertrain, chassis, and body. This subject is extensive. As described in this paper, for use in automotive systems, there are six types of rotational motion sensors, four types of pressure sensors, five types of position sensors, and three types of temperature sensors. Additionally, two types of mass air flow sensors, five types of exhaust gas oxygen sensors, one type of engine knock sensor, four types of linear acceleration sensors, four types of angular-rate sensors, four types of occupant comfort/convenience sensors, two types of near-distance obstacle detection sensors, four types of far-distance obstacle detection sensors, and and ten types of emerging, state-of the-art, sensor technologies are identified.
