## Background
RELATED APPLICATIONS
This application claims priority to U.S. Provisional Application No. 61/365,416 filed Jul. 19, 2010.


FIELD OF THE INVENTION
The present invention relates to systems and methods for controlling and illuminating signage. In particular, the invention relates to illuminating signage and lighting on the exterior of an alternative fuel-based vehicle, and on advertising displays.
BACKGROUND OF THE INVENTION
As oil and other petroleum resources are depleted and become scarcer around the world, the cost of conventional petroleum-based automotive fuels such as gasoline and diesel will continue to rise. With the rise of conventional automotive fuel costs and the desire to limit, reduce, or eliminate air pollution from automobiles and emissions of so-called “greenhouse gases,” the development and sales of electric, hybrid, and other alternative fuel-based vehicles such as liquid natural gas, bio-fuel, hydrogen cars and trucks have increased as well. The term “hybrid” vehicle is commonly used to refer to a hybrid electric-petroleum powered vehicle, with an electric motor powered by electric batteries and an internal combustion engine powered by gasoline, diesel, bio-fuel, or a variety of other fuels. However, the number and percentage of electric, hybrid, and other alternative fuel-powered cars on the road are still small compared to conventional gasoline and diesel-powered vehicles. The cost to develop and manufacture electric, hybrid, or alternative fuel-powered vehicles are typically higher than for comparable conventional gasoline or diesel power vehicles. As a result, these higher costs have contributed to inhibiting sales of electric, hybrid, and other alternative fuel-powered vehicles.
In virtually every city or metropolitan area, traffic congestion on the roads and highways is a fact of life. When drivers, passengers, and their vehicles are caught in traffic congestion, this usually creates significant tension and frustration on the part of millions of drivers and passengers every day. The anxiety of traffic congestion is heightened and feels more emphatically inescapable during rush hours, not to mention road construction or an unanticipated road-clogging accident. Such feelings of tension, anxiety, and stress while ensnared in slow-moving traffic are exacerbated even further with the realization that money used for expensive conventional gasoline or diesel is literally being burned up and completely wasted, day after day, sitting at a standstill or in slow-moving traffic.
Therefore, it is desirable to have a system and method for signaling, marketing, and advertising alternative fuel-based vehicles for others to readily identify the uses and economic benefits of operating an alternative fuel-based vehicle.
SUMMARY OF THE INVENTION
The inventor hereby discloses a system and method for signaling, marketing, and advertising alternative fuel-based vehicles. The system easily installs into newly manufactured and previously existing alternative fuel-based vehicles.
In a preferred embodiment, the system comprises an electronic control unit installed in an alternative fuel-based vehicle, which is connected to at least one sensor connected to the transmission. The transmission is connected to an internal combustion engine and an alternative power source, either one of which drives the wheels of the vehicle. The system further comprises a driver display and in-car display which are both connected to the electronic control unit. The electronic control unit monitors the power status of the vehicle and illuminates displays on the vehicle and transmits a signal to illuminate exterior advertising displays when the vehicle is operating on the alternative power source.

Referring to FIG. 2, vehicle 100 has antenna 207. Vehicle 125 has antenna 207. Vehicle 150 has antenna 207. Vehicle 175 has antenna 207. Vehicles 100, 125, 150 and 175 each have in-vehicle display 204 displaying message 208. Antennae 207 are in wireless connection with antenna 303, which is connected to receiver 302. Receiver 302 is in electronic connection with controller 304. The wireless connection between the vehicles and receiver 302 may be over a direct wireless radio communication link or through an indirect wireless communication link via the Internet using radio base stations in a cellular mobile phone network and an Internet connection to controller 304. Controller 304 creates and controls display 301 on billboard 300, which is based on power status data received from vehicles 100, 125, 150, and 175. Vehicles 100, 125, 150 and 175 each transmit their respective alternative power status to antenna 303 to transmit their respective status to billboard 300 through receiver 302 and controller 304. The statuses are then used to create and display message 301. Further, each vehicle's alternative power status is shown in in-vehicle display 204 as message 208.
In a preferred embodiment, in-vehicle display 204 displays message 208, such as “Ten other cars around you are green vehicles saving money and the environment.” Other similar messages may be displayed as well. Message 301 on billboard 300 displays messages about vehicles in the local area (or a larger geographic region, such as city, state, country, continent or global). For example, “There are ten green vehicles on the road right now. Are you one of them?” Additional advertising messages may be displayed along with message 301 about alternative fuel-based vehicles nearby.
In a preferred embodiment, billboard 300 is a Daktronics digital billboard. Antenna 303 is an antenna suitable for MIMO cellular transmission known in the art. Receiver 302 is a wireless MIMO cellular receiver known in the art connected to a personal computer having a microprocessor and internal memory having programming to count the number vehicles in the fuel-efficient mode. Receiver 302 is connected through the Internet to controller 304. Controller 304 is the Daktronics Visiconn® display management system.
In use, referring to FIG. 3, electronic control unit 200 performs the following steps. At start position 401, electronic control unit 200 first evaluates the operation of alternative power source 104 and internal combustion power source 103 at step 402. At step 403, electronic control unit 200 then determines whether alternative power source 104 is engaged, on, or providing power or torque to transmission 105. If alternative power source 104 is engaged, on, or providing power or torque to transmission 105, electronic control unit 200 determines whether alternative power source 104 is providing power to transmission 105 in an amount greater than a pre-determined amount chosen or set by a user or vehicle manufacturer at step 407. If alternative power source 104 is providing power to transmission 105 in an amount greater than the pre-determined amount chosen or set by a user or manufacturer, then a signal is sent to displays 205 and billboard 300 through transmitter 206, antenna 207, receiver 302, and controller 304 to show that vehicle 100 is operating in a fuel-efficient mode at step 406. If alternative power source 104 is not providing power to transmission 105 in an amount greater than the pre-determined amount, then electronic control unit 200 restarts the evaluation at step 401.
If alternative power source 104 is not engaged, on, or providing power or torque to transmission 105, then electronic control unit 200 determines whether internal combustion power source 103 is engaged, on, or providing power or torque to transmission 105 at step 404. If not, then electronic control unit 200 restarts the evaluation at step 401. If internal combustion power source 103 is engaged, on, or providing power or torque to transmission 105, then electronic control unit 200 evaluates whether internal combustion power source 103 is operating in a reduced capacity mode at step 405. If not, then electronic control unit 200 restarts the evaluation at step 401. If internal combustion power source 103 is operating in the reduced capacity mode, then a signal is sent to displays 205 and billboard 300 through transmitter 206, antenna 207, receiver 302, and controller 304 to show vehicle 100 is operating in a fuel-efficient mode at step 406.
At step 407, a pre-determined amount may be any chosen power amount a user or manufacturer desires for alternative power source 104 to overcome. For example, if alternative power source 104 is providing 0.1%, 1%, 25%, 50%, 75%, or 100%, or any amount in between 0% and 100% of the propulsion power for vehicle 100.
At step 405, internal combustion power source 103 is operating in a reduced capacity if, for example, internal combustion power source 103 is operating on less than all available engine cylinders.
At step 406, the displays to which the signal is sent to illuminate are displays 205 located on the vehicle, inside the vehicle, or on an exterior display, such as billboard 300.
It will be appreciated by those skilled in the art that modifications can be made to the embodiments disclosed and remain within the inventive concept. Therefore, this invention is not limited to the specific embodiments disclosed, but is intended to cover changes within the scope and spirit of the claims.
