    • Provided are a passive entry system for changing a scan method to reduce battery consumption of a smart key and a method for performing a function thereof. In the passive entry system, a smart key ECU periodically transmits a low-frequency scan signal for detecting the smart key. When the smart key being in a slip state is located within a receiving radius of the scan signal, the smart key receives the scan signal and is converted into an active state. Battery consumption of the smart key can be reduced because the smart key normally being in the slip state is converted into the active state when receiving the scan signal from the smart key ECU. Furthermore, the smart key is converted into the active state only within the low-frequency scan signal receiving radius formed near an automobile and requests the smart key ECU to perform a function of the automobile, for example, a function of closing/opening doors. Accordingly, a reliable passive entry system can be achieved.
    • 提供了一种用于改变扫描方法以减少智能钥匙的电池消耗的被动进入系统以及用于执行其功能的方法。 在被动进入系统中,智能钥匙ECU周期性地发送用于检测智能钥匙的低频扫描信号。 当处于滑动状态的智能钥匙位于扫描信号的接收半径内时,智能钥匙接收扫描信号并转换成活动状态。 当从智能钥匙ECU接收到扫描信号时,通常处于滑动状态的智能钥匙被转换成活动状态,可以减少智能钥匙的电池消耗。 此外,智能钥匙仅在形成在汽车附近的低频扫描信号接收半径内被转换为有效状态,并请求智能钥匙ECU执行汽车的功能,例如关闭/打开车门的功能。 因此,可以实现可靠的被动进入系统。
