Abstract

An electric steering locker, includes: a lock member moved by means of a drive source between: a locking position preventing a rotation of a steering shaft, and an unlocking position allowing the rotation of the steering shaft; a position sensor sensing that: the lock member moves from the locking position to the unlocking position, and the lock member moves from the unlocking position to the locking position, the position sensor, including: a plurality of pressers moving with the lock member, and a single switch having a contact point turned on and off by the pressers; and a controller sensing the locking position and the unlocking position of the lock member based on the number of ons-offs of the single switch.

Description

technical field [0001] The invention relates to an electric steering lock for locking the rotation of a steering shaft of an automobile, and to a control method of the electric steering lock. Background technique [0002] Japanese Patent Unexamined Publication (JP2005001497) discloses a steering lock device 1 having a plurality of switches including a lock switch 41 and an unlock switch 42 . [0003] However, the conventional steering lock device 1 described above is costly since it uses a lock switch 41 for sensing a locked position of the lock lever 30 and an unlock switch 42 for sensing an unlocked position of the lock lever 30 . Contents of the invention [0004] Therefore, an object of the present invention is to provide an electric steering lock and a control method of the electric steering lock, which reduce the number of limit switches for exceeding the locked position and the unlocked position, thereby reducing the cost. [0005] According to the first aspect of ...
