摘要： Methods and apparatus are disclosed herein to center a steering wheel. An example vehicle includes a steering position sensor to identify a steering wheel position, a pinion angle identifier to compare a first steering position angle to a second steering position angle, the second steering position angle corresponding to a centered steering wheel position, and an angle modifier to adjust the first steering position angle to match the second steering position angle.

摘要： A steering angle calculating circuit includes a first neutral point calculating circuit, a second neutral point calculating circuit, and an absolute angle calculating circuit. The first neutral point calculating circuit calculates a motor neutral point (θm01), based on a steering angle detected by a steering sensor and a rotation angle of a motor detected by the relative angle sensor, when a drive source for driving a vehicle is started. The second neutral point calculating circuit calculates a motor neutral point when the steering angle detected by the steering sensor falls within a predetermined angle range in which a specific stroke with respect to the steering angle is constant. After the motor neutral point is calculated by the second neutral point calculating circuit, the absolute angle calculating circuit calculates the steering angle as an absolute angle, using the motor neutral point calculated by the second neutral point calculating circuit.

摘要： A torque compensation apparatus for a Motor Driven Power Steering (“MDPS”) system including: a column torque sensor configured to detect column torque applied to a steering shaft; a steering angle sensor configured to detect a steering angle of a steering wheel; and a controller configured to calculate a compensation ratio by sudden steering, based at least one of the column torque detected by the column torque sensor and a steering angular velocity calculated from the steering angle detected by the steering angle sensor. The basic assist torque outputted from the MDPS system is then compensated for according to the compensation ratio.
