Linear Hall Sensors for Electric Power Steering Systems

Programmable linear TLE₄₉₉8C4 Hall sensors developed by Infineon will be used in numerous automotive models. Infineon’s two Hall sensors are used in the Volkswagen electric power steering systems, manufactured in Braunschweig, Germany, for performing precise steering torque sensing.

They are also used for sensing the exerted steering force and steering angle, and transmit this data to the regulatory unit of the electrical power steering device. Thus this functionality helps regulating the motor accountable for electric power steering with respect to energy and force. The Hall sensors are integrated into the sensing module of the system provider to the Braunschweig Business Unit named Valeo Schalter und Sensoren.
