Abstract:
1. An electric steering lock for locking and unlocking a steering shaft having a socket, the electric steering lock comprising: a steering lock mechanism including: a detection means for detecting at least one of the operation states, including the lock state and the unlock state, of the steering lock mechanism and for outputting a detection signal when shifting to the at least one of the operation states is completed; a state holding means, connected to the detection means, for generating a hold signal held at a voltage that is the same as that of the detection signal and for outputting a completion signal indicating that shifting to the at least one of the operation states has been completed in accordance with at least one of the detection signal, provided from the detection means, and the hold signal; and a control means, connected to the detection means and the state holding means, for determining whether or not shifting to the at least one of the operation states has been completed based on the detection signal, the control means providing a state hold command to the state holding means in response to the detection signal, wherein the state holding means holds the detection signal in response to the state hold command to output a hold signal corresponding to the voltage of the held detection signal.
