<p><P>PROBLEM TO BE SOLVED: To provide an electric steering lock device capable of determining the occurrence of failure even when both failures on a detection means side and control side occur at the same time, and of reducing the number of detection means. <P>SOLUTION: The device comprises a lock member capable of moving between a locked position preventing rotation of a steering shaft and an unlocked position allowing rotation thereof, a first detection switch SW1 for detecting a locked state of the steering shaft, a second detection switch SW2 and third detection switch SW3 for detecting an unlocked state of the steering shaft, and an electric steering lock control part 30 for controlling the drive of a lock member by determining a position of the lock member on the basis of detection outputs of the first detection switch SW1 and second detection switch SW2, and outputs to the vehicle side control part 31 the lock/unlock information from the electric steering lock control part 30 and detection outputs of the second detection switch SW2 and third detection switch SW3. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
