摘要： A vehicular steering system can suppress steering of steerable road wheels in a direction not intended by a driver. A steering mechanism steers the steerable road wheels in accordance with a steering wheel and an auxiliary steering angle superposition mechanism. A calculation section calculates a target auxiliary steering angle corresponding to a steering wheel angle of the steering wheel. A detection section accurately detects the auxiliary steering angle based on detection signals of a rotation angle sensor that detects a rotation angle of a rotational member. A driving section controls the auxiliary steering angle superposition mechanism so as to make the auxiliary steering angle coincide with the target auxiliary steering angle. An auxiliary steering angle detection abnormality monitoring section detects abnormality of the auxiliary steering angle detection section. The auxiliary steering angle detection section includes a counting section that counts the number of revolutions per minute of the rotational member.

摘要： The invention proposes an electrically operated power steering controller for inputting a driving electric current offset value of higher accuracy and being able to make an offset correction of a driving electric current by using this driving electric current offset value of higher accuracy, and an adjusting method of this driving electric current offset. Therefore, an electric motor driving electric current measuring device of accuracy higher than that of an electric motor driving electric current detector assembled into a controller CNT is prepared separately from this electric motor driving electric current detector. The driving electric current offset value of high accuracy is outputted by this electric motor driving electric current measuring device. An input device for receiving the driving electric current offset value of high accuracy from the driving electric current measuring device is arranged in an offset correcting device or an offset signal generator within the controller.
