摘要：A steering angle θt detected by the torque sensor is read at S900. Then, anelectrical angle θm corresponding to a motor rotational angle is read at S902. At S908through S922, motor rotational numbers are calculated based on θt, θm and therotational number of a handle, and a correct rotational number of the handle is

calculated from the motor rotational number which is the nearest to an integer of all ofthe calculated motor rotational numbers. Thereafter, an absolute steering angle which isnot influenced by various errors is calculated based on the calculated rotational numberof the handle and the steering angle θt detected by the torque sensor.
