ELECTRIC STEERING LOCK |
摘要 |
An electric steering lock capable of outputting a signal correctly indicating an operation state of a steering lock mechanism even when the operation voltage of a lock detector decreases. The electric steering lock includes a CPU, a signal hold circuit, and an OR circuit. When the steering lock mechanism unlocks a steering wheel, an unlock sensor provides an H level detection signal to the CPU and the signal hold circuit. In response to the detection signal, the CPU issues a state hold command to the signal hold circuit. In response to the state hold command, the signal hold circuit generates an H level hold signal in correspondence with the detection signal. The OR circuit provides an H level signal to an immobilizer ECU when at least one of the detection signal from the unlock sensor or the hold signal has an H level. |
