PROBLEM TO BE SOLVED: To correctly determine the absolute neutral position of steering even in low-speed running, and enable steering without incompatibility in correcting an absolute neutral position signal. SOLUTION: In the step S21, the absolute neutral position signal is input from a steering angle detecting mechanism 16 to a controller c, and an updated absolute neutral position signal is input in the step S22. In the step S23, the controller c compares a solenoid current command value I1 based on a current absolute neutral position signal with a post-update estimated solenoid current command value I1. In the case where the current point α and an estimated point βare the same current command value, the control is conducted according to the absolute neutral position updated in the step S24. When it is determined that the current point α and an estimated point β do not match in the step S23, it advances to the step S25, and the control is continued according to the current absolute neutral position. |
