    • An emergency vehicle transmits a Vehicle Present Signal when in transit on public roads responding to an emergency. The signal can include information relating to the type of emergency vehicle, local highway and terrain data, and the location, speed and direction of travel of the emergency vehicle. When the Vehicle Present Signal is detected by a first vehicle, a functional circuit within the first vehicle calculates the distance between the emergency vehicle and the first vehicle. If the vehicles are within a predetermined distance, a warning signal activates one or more warning systems, thereby notifying the driver of the first vehicle that an emergency vehicle is in the vicinity. A dead-band defined by first and second predetermined distances can be incorporated to prevent rapid cycling of the warning signal.
    • 紧急车辆在紧急情况下在公路上过境时,发送车辆信号。 该信号可以包括与紧急车辆的类型,本地公路和地形数据以及紧急车辆的行驶的位置,速度和方向有关的信息。 当第一车辆检测到车辆当前信号时,第一车辆内的功能电路计算紧急车辆与第一车辆之间的距离。 如果车辆在预定距离内,则警告信号激活一个或多个警告系统,从而通知驾驶员第一车辆紧急车辆在附近。 可以结合由第一和第二预定距离限定的死区,以防止警告信号的快速循环。
