Steering angle sensors (SAS) are critical components in modern vehicles, acting as the vital link between the driver’s steering input and the car’s electronic control systems. Installed within the steering column, these sensors continuously monitor the steering wheel’s position, rotation speed, and direction, converting these movements into precise electronic signals. This real-time data is indispensable for a range of advanced safety and driver assistance feature, referred to ADAS. The primary function of a steering angle sensor is to determine exactly where and how the driver intends to steer, ensuring that the vehicle’s wheels respond accurately to steering wheel movements. The sensor uses technologies such as optical encoders or magnetic sensors to measure the angle and rate at which the steering wheel is turned, providing feedback that is accurate to within a fraction of a degree. For redundancy and reliability ... read more
