Where is the steering angle sensor installed?

[Amanda]

The steering angle sensor is installed at the bottom of the steering column. The steering angle sensor is a device used to detect the rotation angle and direction of the steering wheel. It is a device for determining the angular position of a shaft, such as a steering column, which includes a coil set, a coil support, and a coupler element. The coupler element has a coupler angular position related to the angular position of the shaft. Additional information: 1. The automotive steering angle sensor is used to detect the rotation angle and direction of the steering wheel. Whether the steering wheel turns left or right, it will be detected by the steering angle sensor, enabling the vehicle's electronic control unit to issue the correct steering command. The rotation angle of the steering wheel provides the basis for the vehicle to achieve the steering amplitude, allowing the car to drive according to the driver's steering intention. 2. The steering angle sensor consists of photoelectric coupling elements, perforated slot plates, etc. The photoelectric coupling elements are light-emitting diodes and photosensitive transistors. The perforated slot plate is placed between the light-emitting diode and the photosensitive transistor. The perforated slot plate has many small holes. When the steering wheel turns, the perforated slot plate follows the rotation. The photosensitive transistor operates based on the light passing through the perforated slot plate and outputs a digital pulse signal. The vehicle's electronic control unit uses this signal to identify the steering angle, direction, and speed of the steering wheel.
