    • 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.
    • 一种能够输出正确指示转向锁定机构的操作状态的信号的电动转向锁定,即使当锁定检测器的操作电压降低时。 电动转向锁包括CPU,信号保持电路和OR电路。 当转向锁定机构解锁方向盘时,解锁传感器向CPU和信号保持电路提供H电平检测信号。 响应于检测信号,CPU向信号保持电路发出状态保持命令。 响应于状态保持命令,信号保持电路根据检测信号产生H电平保持信号。 当来自解锁传感器或保持信号的检测信号中的至少一个具有H电平时,OR电路向防盗器ECU提供H电平信号。
