    • An in-vehicle communication system configured to receive signals from a transmitter configured to transmit periodically a time-reference signal and receiver specific information. An information transmission time of receiver specific information is timed relative to a reference transmission time of the time-reference signal. The system includes a receiver characterized as having a receiver identification value. The receiver is configured to operate from an off-state to an on-state during an information-expected time interval to receive receiver specific information. The information-expected time interval is determined based on a reception time of the time-reference signal and the receiver identification value. This provides a way to ensure that the transmitter only transmits messages when it knows the intended receiver is on. It also ensures that the receiver is on only when messages that for that receiver are expected to be received.
    • 车载通信系统,被配置为从配置成周期性地发送时间参考信号和接收机特定信息的发射机接收信号。 接收机专用信息的信息发送时间相对于时间基准信号的参考发送时间定时。 该系统包括一个特征在于具有接收机识别值的接收机。 接收机被配置为在信息预期时间间隔期间从关闭状态到接通状态操作以接收接收机特定信息。 基于时间参考信号的接收时间和接收机识别值来确定信息预期时间间隔。 这提供了一种确保发射机在知道预期的接收机已经开启时才发送消息的方法。 它还可以确保接收器仅在预期接收到该接收器的消息时才接通。
