    • An apparatus for driving an actuator loaded on an automotive vehicle in accordance with ON-OFF operation of an operation switch includes: an operation switch; an input circuit activated by operation of the operation switch for driving the actuator; an input detecting section for detecting whether the input circuit is in an activated or deactivated status; a storing section for storing the detected status of the input circuit; a comparing section for comparing a present status of the input circuit newly detected by the input detecting section with a previous status of the input circuit stored in the storing section; an informing section for providing external information indicative of a mismatch between the present status and the previous status of the input circuit on the basis of comparison results of the comparing section; and a stored status updating section for updating the previous status stored in the storing section on the basis of the newly detected present status after the present status and the previous status have been compared with each other. When the operation switch is operated to the ON-state, if the informing section does not provide external mismatch information the apparatus thus indicates that at least one of the operation switch and the input circuit is operating abnormally, while if the informing section does provide the external mismatch information, the apparatus is indicating that both the operation switch and the input circuit are operating normally.
    • 根据操作开关的ON-OFF操作来驱动装载在机动车辆上的致动器的装置包括:操作开关; 通过操作开关激活的输入电路,用于驱动致动器; 输入检测部分,用于检测输入电路是处于激活状态还是去激活状态; 存储部,用于存储检测到的输入电路的状态; 比较部分,用于将由输入检测部分新检测的输入电路的当前状态与存储在存储部分中的输入电路的先前状态进行比较; 通知部分,用于根据比较部分的比较结果提供指示当前状态和输入电路的先前状态之间不匹配的外部信息; 以及存储状态更新部分,用于根据当前状态和先前状态之间的新检测到的当前状态来比较存储部分中存储的先前状态。 当操作开关操作为接通状态时,如果通知部分不提供外部不匹配信息,则装置因此指示操作开关和输入电路中的至少一个异常地操作,而如果通知部分确实提供 外部不匹配信息,该装置指示操作开关和输入电路都正常工作。
