Abstract
Disclosed herein are a steering angle sensing device and a torque angle sensor module having the same. The steering angle sensing device includes a main gear rotating at the same angle as a steering shaft, a first sub-gear rotatably engaging with the main gear, a second sub-gear rotatably engaging with the main gear and having a number of teeth different from that of the first sub-gear, a third sub-gear rotatably engaging with the main gear and having a number of teeth different from that of each of the first sub-gear and the second sub-gear, a first magnetic sensor detecting a change in magnetic force of the first sub-gear, a second magnetic sensor detecting a change in magnetic force of the second sub-gear, a third magnetic sensor detecting a change in magnetic force of the third sub-gear, and a control device calculating a steering angle from the change in magnetic force detected by each of the first magnetic sensor, the second magnetic sensor, and the third magnetic sensor.
