This is an originally filed provisional application.
The present invention is in the technical field of broadcast notification systems for vehicle drivers.
Each year in the United States collisions between dispatched emergency response vehicles and passenger vehicles take the lives of many emergency responders and civilian drivers. According to the National Highway Traffic Safety Administration approximately 200 people each year are killed and many thousands more are injured in collisions involving emergency vehicles responding to calls for service. From the year 2000 to the time of this filing, more than 150 law enforcement officers have been killed and thousands more officers have been injured as a result of collisions with vehicles while responding to calls or attending to incidents along the roadways. Similar statistics are known for tow truck drivers, construction and road maintenance workers and for children boarding and debarking a school bus. To prevent these tragedies there is a need for a robust notification system that warn vehicle drivers about approaching emergency vehicles, the presence of road workers, busses and other roadside incidence.
Emergency and other roadside vehicles such as maintenance workers and busses have historically used flashing lights and audible horns or sirens to notify the public of their presence. However, visual and auditory signals remain inadequate as oftentimes drivers may have obstructed visibility or audible awareness and remain unaware of these indicators.
To overcome these limitations, it has been attempted to program and control traffic signals to allow traffic to flow only in the direction of the responding emergency vehicle. However this approach is limited in that not all geographic areas are covered with signals and it does not provide notice to vehicles travelling in the same direction as the emergency vehicle. Additionally, the system does not address the situation when a vehicle is stopped on the road in the direction of the emergency vehicle.
Attempts have been made to use AM and FM radio signals to provide localized signaling. This approach is also limited in that the nature and specific details of the incident are not communicated. These systems generally override or over power other RF broadcasts in the area and use the vehicles radio system which are within range as the communication channel. To displace other broadcasts, the power output and bandwidth required for these systems far exceeds the allowed limits set by the FCC, causing interference with all RF devices within range. Further, if a driver is listening to recorded sound such as a digital CD or audio player and does not have the radio turned on no signal is received by the motorist.
Some systems have attempted to provide dedicated transmitter/receiver systems with selective messages to be broadcast; however, the system is limited in that it is a one way systems that requires the user to manually select the message type that will be transmitted, which can be impracticable in many situations. Additionally, these systems have limited range and cannot provide warning to vehicles approaching the scene until such vehicle is in range of the incident.
The present disclosure overcomes the limitations of the prior art and addresses the unsolved need for a broadcast notification system directed to providing messages to alert drivers. It is therefore an object the current inventive broadcast notification system to provide broadcast notifications to vehicle drivers related to vehicle collisions, roadside conditions, dispatch of emergency vehicles and the presence of other stopped roadside vehicles, such as tow trucks, maintenance and repair work vehicles and buses.
Another object of the current invention is to provide a system that can be configured to alert motorist to the presence and directional location of a dispatched emergency response vehicles.
It is also an object of the invention to provide motorist approaching highway work zones a broadcast alert to possible changes in the road and traffic conditions, allowing drivers to proceed safely through construction areas.
Another object of the invention is to provide a system that can provide drivers with broadcast alerts of crashed vehicles and other environmental road hazards.
It is another object of the invention to provide a system that provides motorists notice of a stopped school bus in the area that is loading or unloading children.
It is yet another aspect of the current invention to provide a motorist notice of tow truck operators responding on the interstate.
In another aspect of the invention, a notification is automatically generated by a vehicle to warn other vehicle.
A further aspect of the present invention is to provide to motorists emergency vehicle location and directional data.
Another aspect of the invention is to provide a system for vehicle to vehicle notification for motorists of sudden deceleration and collisions.
It is yet a further aspect of the current invention to mute a vehicle audio or entertainment system to provide for communication of driving events though a vehicles audio speaker or a driver's smart phone.
These and other objects of the invention may be found from a fair reading of the description of the preferred embodiment taken along with the drawings appended hereto. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not necessarily restrictive of the present disclosure.

The scope of protection sought by the inventors may be gleaned from a fair reading of the claims that conclude this specification.
The numerous advantages of the disclosed invention may be better understood by those skilled in the art by reference to the accompanying figures in which:
Reference is now made to the disclosed subject matter, which is illustrated in the accompanying figures. The emergency broadcast notification system of the current invention is broadly implement as demonstrated in
With reference to
During the configuration mode, the module 201 quires the vehicle for vehicle identification and vehicle specification data. The vehicle data is received by the module 201 at a data bus interface 204 through a data connection with a vehicle data bus system 250. During the initial installation, the module 201 may access the vehicle data and determine the type of vehicle in which it is being installed. Vehicle data can be structured as pure digital to digital or analog to digital. There are many well know analog to digital convertors for implementation of the analog to digital embodiment.
Data from various vehicle devices associated with the vehicle bus system 250 can be used to create data profiles to trigger broadcast messages representative of the type of vehicle the module 201 is installed and the message type that will be broadcast. For example,
The module 201 is further comprised of a memory 212 for storing a library of voice and broadcast notifications or other messages that can be accessed for broadcasting or play back.
Broadcast messages 1 through 13 are stored in the module memory 212, which can also be accessed during the programming mode to allow for recording of individualized or unique massages that can be added to the library 212 and triggered upon the occurrence of a specified event. Preferably each message 1 through 13 is pre-recorded into memory 212 at the time of manufacturing. The library 212 can come with prerecorded voice and broadcast notices in the form of an audible alert, siren or voice messages comprising various alert notifications and reminder messages to warn motorist of emergency or driving events in their vicinity that require their immediate attention.
The module 200 includes a communication module 210 using radio frequency (RF) transceiver to allow communication between a plurality of modules 200. Each broadcast notification 1 through 13 is preferably transmitted at 2.4 GHz, which is a band dedicated to short range communication devices, including Bluetooth, ZigBee, and other IEEE transmission protocols. The communication module 210 can be a one way system or preferably a two way transmitter/receiver system that can transmit an RF signal at least 1500 feet and preferably up to 3000 feet. The communication module 210 is associated with an antenna (not shown) that enhances the transmission and receipt of RF signals between a plurality of modules 200. The antenna may be the vehicle antenna associated with the vehicle radio or may be a standalone antenna that is dedicated to the communication module 210.
During the operating mode, after being received, the broadcast notifications 1 through 13 may be presented to vehicle drivers through the module 200 by a number of interface modalities such as light flashes, electronic display, LED screen, but is preferably a voice synthesizer (206) that generates a voice message projected by a small speaker 214. In one embodiment of the invention, a short range local RF communication link is provided to allow communication of broadcast notifications 1 through 13 to local devices such as smart phones or hand held audio players. The communication link in this embodiment is any form of local RF, but is preferably the Bluetooth® standard. The local communication link provides notices 1 through 13 directly to a smart phone or other device that is within the vehicle range of the broadcast signal.
Each module 201 can be customized and provided individualized messages at the time of start of a vehicle ignition. Messages may be programmed by the car dealer that sells the vehicle to trigger upon receipt by the controller of specified data input from the vehicle bus 250. For example, oil changes at specified odometer readings.
Further, the module 200 can be used as a communications relay to retransmit the originally received message to other nearby modules 200, acting to amplify the range of notification to surrounding vehicles 120, thus expanding the overall area of coverage. If desired for a particular application the RF signal can be focused to make the signal directional using known signal reflecting and other signal cancellation and redirection techniques.
Each module 200 may also comprise a motion, accelerometer, crash or shock sensor means 216 to provide sensing of a sudden vehicle deceleration or that a vehicle collision has occurred. Airbag deployment data from the BCM 260 may also trigger an input to the module 200 and initiation a crash broadcast message. Upon receiving a sensor input indicating a sudden deceleration, the module 200 transmits a signal to alert other vehicle drivers in the vicinity of the impact incident occurring in the vehicle ahead.
Each module 200 is further comprised of an audio output device 214. The audio output 214 can be any well know means for generating an audible sound such as a transducer. Preferably, the module 200 interfaces with the vehicles data bus system to provide an audible message through the bus 250 to the vehicles entertainment system. The module 200 may also be hardwired into the audio head unit with an RCA jack or other electrical connection. The module 200 may include a small stand alone speaker or speaker box that is connected to the module 200 by way of a standard electrical audio jack.
Each module 200 may contain an audio mute circuit 218 that over rides and mutes vehicles' sound system or the driver's cellular phone to assure the broadcast notification is clearly heard by drivers. The mute function can be accomplish by a variety of well known means such as software or power cut off circuit. In the case of a driver's cell phone, muting is preferably accomplished using low energy Bluetooth® communication between the module 200 and the driver's phone, which have previously been paired. In the case of the vehicle's entertainment system, the interface 204 provides a mute signal to the vehicle's audio system 272 through the vehicle's data bus 250. Once the audio system 272 has been muted, and the alert message has played or the receipt of broadcast has stopped, the audio system 272 returns back to its original playing mode. It will be appreciated by one skilled in the art that the mute function can be performed by direct interface with the vehicle audio head unit.
Power and ground for the module 200 is managed by a power management circuit 220 and is preferably provided by direct connection to the vehicle's electrical system and may include a battery backup (not shown). The direct connection can be provided by use of a power jack inserted into the vehicle's cigarette lighter or similar plug, or it may be through physical hard wiring to the vehicle's 12 volt power circuit. Power can also be provided from the lights and siren system of an emergency response vehicle.
The transmitting module may collect from the emergency vehicle real time GPS location data 340 that will be packaged with the broadcast notice 363 and transmitted 370 in the message. It will be appreciated by one skilled in the art that there are many know types of GPS data collection means. Location data broadcast by the transmitter is compared to the location data obtained in the receiver to provide motorists with information regarding distance to and direction of the emergency vehicle. When the system alerts motorist to the approach of an emergency vehicle, or of their approach to an emergency vehicle tending to a roadway incident, those drivers will have the time to examine their surroundings and select a safe route to move out of the way of that emergency vehicle, thus allowing for safe passage through traffic for all.
In another embodiment, the module may be installed in school buses to alert other drivers in proximity of the presence of the stopped school bus, children loading, unloading or crossing the roadways and the posted speed limit.
In another embodiment, the module can also be utilized to alert drivers of passenger vehicles equipped with similar modules to collisions that have occurred ahead and other adverse traffic conditions such as dense fog, wet road and road debris. Similar to other embodiments,
It is anticipated that any number of roadside or traffic conditions can have associated notifications. For example, if the windshield wipers are in motion and the temperature is below 32 degrees, a notice can be transmitted that it is snowing. If the wiper are in motion and it is above 32 degrees, the message transmitted is that it is raining, wet roads proceed with caution. If traction control data is received, then a notice that the roads are icy, proceed with caution is sent.
In yet another embodiment, the module is installed in tow truck, road construction or road maintenance crew vehicle to provide notification to approaching drivers. Motorist approaching highway work zones can be alerted to possible shifts in traffic lanes allowing them to proceed safely through those areas. Tow truck operators responding on the interstate can work in a safer environment because the system functions to alert motorist to their presence and to use caution. “Warning, there is an emergency vehicle responding to an incident ahead. Vacate the lane nearest the emergency vehicle or slow down 20 miles an hour under the posted speed limit if unable to change lanes”.
In another embodiment, the module can be configured for installation in a train or at a railroad crossing gate. When a railroad crossing gate is lowered, the module sends a notification of an approaching train and lowered railroad crossing gate.
