<p><P>PROBLEM TO BE SOLVED: To provide an electric steering lock device in which signals of lock completion and unlock completion of a steering lock are hardly mistakenly output even when the supply voltage to a detection means is changed. <P>SOLUTION: A steering lock ECU 9 has a state maintaining circuit 22 and an OR circuit 23. When the lock of a steering lock 8 is completed, an unlock side Hall IC 21 outputs the ON signal to a CPU 19 and the state maintaining circuit 22. The CPU 19 outputs a command to the state maintaining circuit 22 when the ON signal is input, and the state maintaining circuit 22 outputs the H-level signal by maintaining the ON signal. For example, even when the unlock side Hall IC 21 outputs the OFF signal irrespective of in a low-voltage state, and an unlocked state of the steering lock 8, the steering lock ECU 9 maintains a state that the ON signal is output from an output terminal 9a by the H-level signal output by the state maintaining circuit 22. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
