<P>PROBLEM TO BE SOLVED: To suppress degradation of operability, and controllability and stability even when a vehicular speed sensor fails. <P>SOLUTION: This steering device 10 includes: a right-side steering input part 20R; a left-side steering input part 20L; a vehicular speed sensor 40; a turning mechanism 12 for turning a steering wheel RW in accordance with a steering angle of at least one of the right-side steering input part 20R and the left-side steering input part 20L; and a steering ECU 30 for setting a steering angle ratio being a ratio of a turning angle of the steering wheel to the steering angle of at least one of the right-side steering input part 20R and the left-side steering input part 20L based on the vehicular speed detected by the steering ECU 30. When the vehicular speed sensor 40 fails, the steering ECU 30 sets a first steering angle ratio being a ratio of the turning angle of the steering wheel RW to the steering angle of the right-side steering input part 20R, and a second steering angle ratio being a ratio of the turning angle of the steering wheel RW to the steering angle of the left-side steering input part 20L at values different from each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
