Sensor for detecting steering angle
First Claim
Patent Images
1. A sensor for detecting a steering angle comprising:
- a steering shaft to be rotated by a steering wheel;
a first shaft member operatively connected to the steering shaft so as to be rotated together with the steering shaft;
a first potentiometer operatively connected to the first shaft member for generating first steering angle information in the form of a voltage having one value plural times during rotation of the steering wheel;
a second shaft member operatively connected via a reducer to the first shaft member; and
a second potentiometer operatively connected to the second shaft member for generating second steering angle information which has a one-to-one correspondence with the rotational angle of the steering wheel.

Abstract
During plural rotations of the the first potentiometer as a result of the operation of a steering wheel, though a specific position of the first potentiometer corresponds to plural rotation angles or rotation numbers of the steering wheel, the correct, real or current rotational angle or rotational number of the steering wheel can be obtained by knowing a one-to-one correspondence between a specific position of the second potentiometer and the reduced rotational angle of the steering wheel.
