The control unit for ABS, TCS and ESC determine the wheel speed based on signals sent by the Wheel Speed Sensors. This information is used to prevent the wheels from locking and determine when the wheels are spinning, taking appropriate control action to maintain the vehicle's stability and steering responses. In addition, it is possible to capture the rotational direction - this function supports the hill start assist and the park assistance system, e.g. The wheel speed is measured using the anisotropic magneto-resistance (AMR) effect. This method and the integrated information processing feature enable our latest generation of sensors to handle many functions. Development according to ISO 26262 (Functional Safety Management Requirements).Active Wheel Speed Sensors (AWSS) improve existing vehicle functions and make new vehicle functions possible that cannot be achieved with passive ones.
