PURPOSE: A torque and steering angle sensor is provided to calculate steering assistance torque and to control a steering motor. CONSTITUTION: A torque and steering angle sensor comprises a circuit unit(120), an input unit(110), an output unit(130) and a sub gear(140). The circuit unit comprises a circuit board in which a micro controller unit is installed. The input unit comprises an input shaft magnet and an input shaft hole IC. The input shaft magnet is separated from one side of the circuit board. N-pole and S-pole are alternated in the input shaft magnet. The input shaft hole IC is mounted and fixed in one side of the circuit board. The input shaft hole IC detects the polarity of the rotating input shaft magnet. The output unit comprises an output shaft magnet, an output shaft hole IC and a main-gear. The sub gear comprises a sub gear, a sub magnet and a sub hole IC. |
