The control systems 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.
The wheel speed is measured using the anisotropic magneto-resistance effects as AMR or GMR. These technologies together with the integrated signal processing enable our WSS to provide information of the wheel rotational speed to control systems, such as ABS, TCS and ESC. This method and the integrated information processing feature enable our latest generation of sensors to handle many functions.
