<P>PROBLEM TO BE SOLVED: To provide a vehicular steering device that can easily perform steering control, even when such a partial failure that can detect an operation angular velocity but can not detect an operation angle, in an angle sensor for detecting the operation angle of an operating member. <P>SOLUTION: When a partial failure is detected, a sensor fault determining part 55 switches a control mode from a first control mode to a second control mode. A steering motor 3 is rotationally driven in the direction corresponding to the rotational direction of a steering wheel immediately before the partial failure occurs in the angle sensor 11, if the control mode is changed from the first control mode to the second control mode. Then, when an absolute value of a steering wheel operation angular velocity ωh exceeds a threshold, it is determined that the driver has operated the steering wheel, and the rotational direction of steering motor 3 is reversed to the opposite direction to the present steering direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
