    • In a wireless communication system, a portable device transmits a first signal spread based on a reference period indicated by a synchronization signal transmitted from an in-vehicle device and transmits a second signal spread based on an operation by a user. The in-vehicle device sets a search period based on a variation range in a delay time from when the synchronization signal is transmitted to when the spread first signal is transmitted and sets a residual period that starts at an ending point of the search period and ends at an ending point of the reference period when a starting point of the reference period is set at a starting point of the search period. When the in-vehicle device fails in a synchronous acquisition for the search period, the in-vehicle device performs a synchronous acquisition process for the residual period.
    • 在无线通信系统中,便携式设备发送基于从车载设备发送的同步信号所指示的基准时段扩展的第一信号,并发送基于用户的操作而扩展的第二信号。 车载设备基于从发送同步信号到发送第一信号的延迟时间的变化范围设定搜索周期,并设置从搜索期间的结束点开始的剩余期间 在基准期间的起点设定在搜索期间的起始点的基准期间的终点。 当在搜索期间车载设备失败同步采集时,车载设备对剩余时段执行同步采集处理。

    • An in-vehicle apparatus allows the user to check and adjust tire pressure whenever he/she thinks of doing it, by transmitting, from a portable unit that is carried by the user, a start request signal through UHF band electric wave to forcefully operate sensor units for detecting the tire pressure in each of the tires of the automobile, by collecting the tire pressure information to a control unit of the in-vehicle apparatus, and by displaying the tire pressure on a display unit of the portable unit when the tire pressure information is transmitted from a Bluetooth unit of the in-vehicle apparatus to a Bluetooth unit of the portable unit.
    • 车载设备允许用户通过从用户携带的便携式单元通过UHF频带电波发送启动请求信号来强制操作传感器,来检查和调整轮胎压力。 单元,用于通过将轮胎压力信息收集到车载设备的控制单元中,并且当轮胎压力在轮胎压力下显示轮胎压力到便携式单元的显示单元时,检测汽车的每个轮胎中的轮胎压力 信息从车载设备的蓝牙单元发送到便携式单元的蓝牙单元。
