DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The vehicle remote control system of the present invention
includes a plurality of vehicles and remote control stations. As
illustrated in FIG. 1., a remote controlled car 10 has a front
end 11 and a back end 12. The car 10 of the present invention
includes a camera 13 having a lens 14 with a field of view toward
the front end 11 so as to provide a view of a forward path of
travel of the car 10. A pair of side rear view mirrors 16 are
connected to the front end 11, one on the right side thereof and
the other on the left side thereof. The mirrors 16 are located
within the field of view of the lens 14. The camera 13 produces a
video signal which is sent to transmitter and receiver circuitry
20 so as to be broadcast by an antenna arrangement 22 to a remote
control station. In this manner, the images of objects in front
of the vehicle 10 and in back of the vehicle 10 are transmitted
to the user. An optional microphone 21 connected to the camera 13
may be used to allow sound to be transmitted with the video
signal.
An instrumentation panel 19 is also located within the field of
view of the lens 14. A fuel gauge 26 located within a fuel tank
28 produces a gas level indication signal in accordance with the
amount of fuel which is located within the fuel tank 28. A speed
indicator 30 provides a speed indication signal indicative of the
magnitude of the speed of vehicle 10. Both the speed indication
signal and the gas level indication signal are provided to an
instrumentation panel 19. With the panel 19 also being located
within the field of view of lens 14, an indication of the amount
of fuel left and the speed of car 10 is provided to the user at
the remote control station along with the view of any objects
either directly in front of car 10, or directly behind car 10, or
to either side of car 10.
Transmitter and receiver circuitry 20 further includes circuitry
for receiving a selective remote control signal which control the
motor and steering mechanism 24 of the vehicle 10. In the
preferred embodiment the selective remote control signal is
received by a separate antenna of the antenna arrangement 22. As
stated above, the vehicle remote control system includes at least
one, and preferably a plurality, of vehicles. As illustrated in
FIG. 1, each of the vehicles include a channel selector 32. Each
channel between a remote controlled vehicle and a remote control
station includes a unique video broadcast frequency different
from the other channels and a selective remote control signal
different from other remote control signal located within other
channels, also different from the other remote control channels.
The channel selector 32 allows the user to select which channel
the remote controlled vehicle 10 operates off of. If the user
selects the same channel at his or her remote control station as
is selected on the vehicle 10, the user can remotely control that
vehicle 10 from that remote control station as well as view
objects monitored by the camera 13 of that same vehicle 10.
As illustrated in FIG. 2, a remote control station 34 includes an
antenna arrangement 36 for receiving the video signal and
transmitting the selective remote control vehicle. The antenna
arrangement 36 includes a plurality of antennas, each one
performing a separate function as will be discussed below. Each
remote control station 34 also includes a commercially available
television set connected to the remote control unit of the
present invention. The remote control unit includes various user
inputs 40 for controlling the motor and steering mechanism 24.
For controlling the direction of travel for the car 10, the user
inputs 40 include a steering wheel 42. An accelerator pedal 44 is
provided for allowing the user to control the speed of the car 10,
which increases the farther down the accelerator pedal 44 is
pushed. Further, user inputs 40 include a switch 46 for setting
the path of travel of car 10 in either the forward or reverse
direction.
The remote control unit further includes a two-way radio unit 50
which may be tuned via a radio tuner 52. The two-way radio allows
a user from one remote control station 34 to communicate with
another user at a different remote control station 34. The radio
tuner 52 is manually adjustable by the user to a predetermined
frequency. The radio unit 50 includes voice activated
speakerphone circuitry. A speakerphone speaker 54 allows a user
to hear another user speaking into a condenser microphone 55. The
radio unit 50 allows a user to transmit when he or she speaks
into the microphone 55 after no other transmissions are detected.
As illustrated in FIG. 3, a headphone set 56 and an external
microphone 57 may be used by the user. The headset 56 would plug
into a earphone jack 58 (see FIG. 2) thereby intercepting the
signal which would be sent to the speaker 54. Likewise, once the
microphone 57 is inserted into a microphone jack 59, the voice of
the user transmitted by the radio unit 50 is picked up by the
external microphone 57 instead of the built in condenser
microphone 55.
As illustrated in FIGS. 2 and 3, a channel selector 60 allows a
user to select a channel on which the remote control station 34
operates. As stated above, each channel used within the vehicle
remote control system of the present invention includes a
different video signal and remote control signal so that a remote
control station 34 receives a video signal from and controls only
one vehicle 10 within the system. Control circuitry 62 converts
the user generated commands from user inputs 40 into a remote
control signal having a selective format as determined by channel
selector 60.
Each remote control signal of the various channels within the
preferred embodiment are modulated on the same carrier frequency
and include digital information identifying the channel as well
as the remote control operations to be performed. Once control
circuitry converts the user inputs into the remote control signal
for the selected channel, that remote control signal is modulated
by modulator circuitry 64 and is then sent to a remote control
transmission link, which is an antenna of the antenna arrangement
36 designed for transmitting radio frequency signals.
In the preferred embodiment, each vehicle remote control station
34 includes a video transmission link with the remote controlled
vehicle 10 which is set on the same channel as the television set
and the channel selector 60. Therefore, the channel selector 32
of each remote controlled vehicle 10 selects a channel format for
transmission of the video signal using the national standard code
(NTSC) format for televisions used in the United States of
America so that any commercially available television may be used
as the monitor for the remote control station 34.
Alternatively, a video signal format different from the NTSC
formats may be used. In this instance, control circuitry 62 would
control tuner 71 to establish the video signal channel for
receiving and recovering the video signal via demodulator
circuitry 72 which was modulated and transmitted on the same
channel selected by the channel selector 60. Once the video
signal is recovered by the demodulator 72, the recovered video
signal is sent to modulator circuitry 73. Modulator 73 modulates
the recovered video signal on a channel having an NTSC format and
sends this modulated signal to the television set. Tuner 74
establishes which NTSC channel format modulator 73 uses. Control
circuitry 62 controls tuner 74 in accordance with channel
selected by the user. The television set must be set to that
channel to display the video signal. If an audio signal was
included in the video signal transmitted by the vehicle 10, it is
separated by demodulator 72 and recombined by modulator 73 before
being sent to the television set.
As illustrated in FIG. 4, a conditioning platform for cars not in
immediate use is provided, which either cools or heats a car,
depending on climate, ordinarily. In most cases, a platform 90 is
used to cool the vehicles 10 not in immediate use. During
operation of the vehicles 10, the motors get hot. Between races,
the vehicles 10 may be placed on the cooling platform 90 to allow
the motors to cool. Each cooling platform includes a flat bed 91.
At the back end of the flat bed 91 is a back gate 92 and at the
front end of the bed 91 is a front gate 93. The gates 92 and 93
are pivotally attached to the platform 90. An enclosed bottom
portion 94 located below the flat bed 91 includes an air
conditioning unit 95 to cool the air within the enclosed portion
94 and to pump the air out the plurality of air outlets 96
located on the flat bed 91. Thus, any vehicles 10 located on the
flat bed 91 are cooled by the cold air located within the
enclosed bottom portion 94. Alternatively, unit 95 may be a
heating unit or include a heat generating output as well as a
cooling output. 0f course, in colder climates, a heating output
may be necessary to keep cars warm that are not being used
immediately.
Accordingly, it is to be understood that unit 95 is an air
generating unit that may provide cool air, heated air, or both
heated and cooled air, selectively, depending on need.
Furthermore, a vehicle platform control arm in the configuration
of a wagon handle, for example, can be provided for controlled
movement of the platform from place to place. Of course, the
appropriate gate, in this case, gate 93, will be raised; a single
pair of wheels could be provided on a pivoting axle at this end
of the platform, and the entire platform then moved from place to
place in wagon fashion, much the same as baggage wagons at major
airports are moved from place to place. Thus, platform 90 is
conveniently further employed to store vehicles and can also be
used to transport vehicles to and from storage and the raceway.
While a gasoline car 10 is illustrated in the preferred
embodiment, other drive mechanisms may be used. For example, car
10 may be an electric car and be powered by a battery. In this
case, a battery power level indicator would be used in place of
fuel gauge 26. Further, the instrument panel 19 may provide more
information, such as elapsed time from initial movement of the
car 10, the temperature of the motor, etc. Other sensors would
have to be used to sense these parameters. Other modifications to
the preferred embodiment may include the use of vehicles other
than cars, such as remote controlled planes, helicopters, trains,
boats, or other vehicles.
It is to be understood that the present invention is not limited
to the sole embodiment described above, but encompasses any and
all embodiments within the scope of the following claims.
