How GMR wheel speed sensors help advance vehicle control and braking systems
Giant magnetoresistance sensors are strong candidates for the high-accuracy wheel-speed sensing necessary in autonomous vehicle systems. Christine Graham | Allegro MicroSystems The purpose of a braking system has evolved from simplistic stopping to critical functions in vehicle safety through highly accurate feedback to traction control (TCS) and advanced driver assistance systems (ADAS). These advances have […]
