Increasing use in automotive industry for various applications

The automotive industry has emerged as a major end-use segment for magnetic sensors in modern times. A contemporary vehicle now houses dozens of sensors, controllers, and electronic control units for handling various functions related to engine optimization, emissions control, safety, comfort, and infotainment. Magnetic sensors form an indispensable part of such networked automotive electronic systems, and their adoption is rising steadily owing to several factors.

Vehicle safety systems like anti-lock braking and electronic stability control heavily rely on magnetic speed and position sensors to instantaneously detect wheel slippage or loss of traction. This helps prevent accidents by enabling precise traction control. Sensors also play a key role in advanced driver-assistance features through applications like blind-spot detection, automatic braking and lane-keep assist. As autonomous driving becomes a greater reality, vehicles equipped with highly accurate magnetic angular and linear position sensors can map their surrounds in real-time for self-navigation.

Rising electrification of automobiles has further bolstered the need for magnetic sensors. Electric motors require position tracking of rotors and timing belt for optimized torque generation. Hybrid and electric powertrains too are sensor-intensive with their reliance on sensors to switch smoothly between engine and electric modes. Even non-electric automobiles now commonly employ start-stop technology where magnetic sensors are needed to restart the engine automatically. Infotainment and telematics functions like rear-view cameras also leverage magnetic field sensing for their operation.

Battery management further draws upon magnetic current and temperature measurement to balance charging loads and prevent overheating. As automakers aggressively push for connected car capabilities via features like automatic software updates and remote diagnostics, the use of magnetic sensors as node components linking various ECUs is growing.
