Abstract:
Provided is an apparatus and method for detecting steering information in which a plurality of torque sensors and sensors for sensing a rotation angle of a steering shaft are provided and thus it is possible to calculate steering information, such as a steering torque, a steering angle, etc., even upon occurrence of failure in some sensors. A plurality of torque sensors and absolute angle sensors (rotation angle sensors) are provided, and after it is determined whether an output value of each sensor is synchronized, a torque and a steering angle are calculated accordingly. Therefore, even upon occurrence of failure in some sensors, it is possible to calculate a torque and a steering angle normally, and thus steering control is possible.

Claim (Index 16):
A method of detecting steering information, the method comprising:\n outputting, by first to fourth torque sensors, relative rotation angle information according to distortion of a torsion bar disposed between a steering input shaft (IS) and a steering output shaft (OS); outputting, by first to fourth rotation angle sensors, absolute rotation angle information of the steering IS or OS; a first synchronization checking operation of checking synchronization states of output values of the four torque sensors; a second synchronization checking operation of checking synchronization states of output values of the four rotation angle sensors; a torque calculation operation of calculating a torque value based on at least one of the output values of the four torque sensors according to results of the first synchronization checking operation; and a steering angle calculation operation of calculating a steering angle based on at least one of the output values of the four torque sensors and at least one of the output values of the four rotation angle sensors according to results of the first and second synchronization checking operations.
