The automotive industry has gone along way in terms of developments made in the design and performance of automobiles. Year after year, different car makers introduce more and more feature on their cars not only to appease their customers but also to provide good performance and enhanced safety.
Currently, more and more electronic control systems are being employed in the production of automobiles. In the production of the said advanced features, sensors play key roles.
The most common areas of a vehicle which is equipped with the electronic control systems are the safety and driver convenience features. For these to function properly, the presence of sensors is vital. These sensors act as switches for other electronically controlled feature of a system in an automobile.
As a result of the increasing demand for advanced safety and driver convenience features, the demand for sensors also increases. These sensors are commonly used to detect position, displacement, rotary position, linear position, timing, and angles. Navigation and safety features like the anti-lock braking system are also where these magnetic sensors are widely used.
In a typical anti-lock braking system, a central electronic circuit and four speed sensors are needed.
