[0163] In addition, embodiment of this invention is not limited to what was shown in the said embodiment, For example, it can change and implement as follows. In addition, each of the following modified examples can be applied not only to the above-mentioned embodiment, but also can be implemented in combination with different modified examples.
[0164] a. In the "steering state determination process" of the above-mentioned embodiment, when the steering speed ωs is smaller than the determination value ωa and the motor current Im is greater than the reference value Ix, the steering wheel 2 is confirmed by determining whether the steering state of the steering wheel 2 is a neutral state. Whether the steering state is "neutral state". The determination process for the above confirmation can be changed as follows. That is, it can be confirmed whether the steering state of the steering wheel 2 is the “neutral state” based on whether the state of maintaining the motor current Im w...
