DETAILED DESCRIPTION

[0021] As discussed above, embodiments of the present disclosure relate to vehicular safety devices and more particularly to a non-obtrusive emergency vehicle prewarning system as used to improve roadway safety when an emergency vehicle is in route on an emergency call.

[0022] Generally, the non-obtrusive emergency vehicle prewarning system may comprise a one-way communication system that is configured to warn civilian vehicles of approaching emergency vehicles, and the direction the emergency vehicle is coming from. The non-obtrusive emergency vehicle prewarning system is essentially a two-part system comprising a transmitting device installed in emergency vehicles configured to transmit a signal having an approximate range of about 300 meters. A receiving unit may be installed within civilian vehicles configured to receive the signal within the 300-meter range. The receiving unit is structured and arranged in a non-obstructive manner, and preferably comprises a plurality of indicator options (such as a screen display, a blinking light, and audio cues) to alert the motorist when an emergency vehicle is within range.

[0023] In one embodiment, the display of the receiving unit may comprise a plurality of directional arrows (forward, rear, left, and right) indicating to the motorist the direction the emergency vehicle is traveling from, thereby giving the motorist time to react accordingly. Once the emergency vehicle has passed, or has changed direction, the receiver may return to a standby mode.

[0024] The receiving unit may be in electrical communication with the civilian vehicle electrical systems. In particular, the receiving unit may be in electrical communication with the turn signal lamps and may include a circuit and a software protocol for activating the turn signal lamps. Preferably, the receiving unit is configured to flash all of the turn signal lamps in tandem when a signal is received from the emergency vehicle. For example, as the emergency vehicle approaches the civilian vehicle, the receiving unit receives the emergency signal, and the receiving unit then sends a lamp signal to each turn signal lamp simultaneously which causes each turn signal lamp to flash three times in quick succession. Other flash patterns may be utilized. This system allows the driver of the emergency vehicle to verify that the civilian vehicle has indeed received the emergency signal, and thus, the driver of the emergency vehicle knows that the driver of the civilian vehicle is aware of the presence of the emergency vehicle. An additional advantage of this system is that it can further alert other civilian vehicles who have not yet been made aware of the emergency vehicle but can see the civilian signal with the flashing exterior lamps. Effectively, the receipt signal and flashing extends the range of the system in notifying more civilian vehicles. Alternatively, headlights and taillights, park lamps, fog lights, or other lamps may be used in lieu (or in conjunction with) of the turn signal lamps. While it is preferred that the system utilize lamps that are already integrated into the vehicle, dedicated auxiliary lamps installed with the system may be used as well.

[0025] In some embodiments, the emergency vehicle transmitting unit may be in electrical communication with the turn signal lamps of the emergency vehicle.
