An automotive wheel speed sensor plays a prominent role in day-to-day operations of several wheel on-board systems. The main function of the sensor is to measure the speed of the wheel on tooted wheel or the magnetic encoder seal positioned on the bearing. The recent advancements achieved in technologies in vehicles has enabled the use of automotive speed sensors for transmitting data to various systems which are responsible for controlling various vehicle dynamics as well as an extensive range of supplementary purposes. Automotive wheel speed sensors are also referred to as ABS speed sensors as they observe the speed of a vehicle from its tone wheel. An automotive speed sensor transmits speed readings to an Electronic Control Unit (ECU) which takes appropriate decisions regarding break pressure adjustments during critical situations. Ensuring driver and road safety is one of the prominent challenges at present and it is estimated to stay a challenge in future as well. One of the main reasons for several road accidents is the slow reaction of the driver while responding to accidental situation while driving at a higher speed. High-tech automotive wireless electronics is capable ...
