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 1):
An apparatus for detecting steering information, the apparatus comprising:\n first to fourth torque sensors configured to sense a relative rotation angle according to distortion of a steering input shaft (IS), a steering output shaft (OS), and a torsion bar disposed between the steering IS and OS; first to fourth rotation angle sensors configured to sense an absolute rotation angle of the steering IS or OS; a first synchronization checker configured to check synchronization states of output values of the four torque sensors; a second synchronization checker configured to check synchronization states of output values of the four rotation angle sensors; a torque calculator configured to calculate a torque value based on at least one of the output values of the four torque sensors according to check results of the first and second synchronization checkers; and a steering angle calculator configured to calculate 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 the check results of the first and second synchronization checkers.
