摘要： 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.
摘要翻译：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。

摘要： A wireless wake-up system and an operation method thereof are provided to optimize power consumption when wireless data is received. The wireless wake-up system activates a wake-up detection module and then compares a wireless input signal received through an antenna with a pre-stored reference value. If the wireless input signal is equal to the reference value, the wireless wake-up system determines that the input signal is a wake-up signal with a low bit rate, and then generates a wake-up command corresponding to the wake-up signal. Also, the wireless wake-up system activates a selected module kept in an inactive state by sending the wake-up command to the selected module. The activated module may be a microcontroller unit (MCU). When the MCU is activated, the wireless wake-up system may inactivate the wake-up detection module.
摘要翻译：提供无线唤醒系统及其操作方法以在接收无线数据时优化功耗。无线唤醒系统激活唤醒检测模块，然后将通过天线接收的无线输入信号与预先存储的参考值进行比较。如果无线输入信号等于参考值，则无线唤醒系统确定输入信号是具有低比特率的唤醒信号，然后产生对应于唤醒信号的唤醒命令。此外，无线唤醒系统通过向所选择的模块发送唤醒命令来激活保持在非活动状态的选定模块。激活的模块可以是微控制器单元（MCU）。当MCU被激活时，无线唤醒系统可以使唤醒检测模块失活。
