PARKING SENSOR/OBSERVATION SYSTEM ADD-ON FOR A VEHICLE
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to vehicle parking sensors and vehicle backup
cameras, and more particularly, to aftermarket devices therefor.
2. Discussion of the Related Art
Parking sensors are a technology that allows the driver of a vehicle to be
alerted to
nearby objects in their path. Parking sensors are also known as backup
sensors, parking
sonar or just sonar depending on the automaker. While there are variations in
the design
and features of these systems, the basic design puts sensors in the vehicle's
bumper. These
sensors send ultrasonic waves at 40,000 times per second to detect obstacles
behind the
vehicle. A controller installed inside the vehicle receives the signal from
the sensors and
transmits it to a speaker that emits a tone, or to a combination speaker and
display unit.
A backup camera system, such as those found in many SUVs, minivans and luxury
vehicles shows a driver what is behind them as they are reversing and displays
it on the
vehicle dashboard LCD so that the driver can avoid accidents. Such a system
generally
includes a camera mounted onto the rear of a vehicle, a display device mounted
in the
interior of the vehicle and the necessary wiring.
For vehicles that do not have built-in parking sensors or a backup camera
system,
aftermarket systems are available. Some aftermarket systems are mountable on a
vehicle's
license plate. License plate mounting of an aftermarket system can obstruct
parts of the
license plate that must be legally visible. Examples of license plate parts
with legal
1
CA 02684783 2009-11-06
visibility requirements include a registration sticker, State or County name.
Further, in
aftermarket systems that are only license plate mountable, the parking sensors
may not be
positionable for optimal detection of objects behind the vehicle.
Accordingly, there is a need for an aftermarket system with backup camera
and/or
parking sensor capabilities that does not obstruct license plate parts with
legal visibility
requirements and that can be positionable for optimal object detection.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
In accordance with an exemplary embodiment of the present invention, there is
a
provided a parking sensor/observation system add-on for a vehicle. The system
may
include only parking sensors or a combination of parking sensors and a camera.
The
system includes a bar that can be easily mounted to a vehicle's license plate.
However, the
bar can also be mounted below a vehicle's bumper or on the bumper, depending
on which
mounting scheme provides the best viewing and/or sensing position, for
example. The
system includes mounting brackets and hardware for this purpose.
In a parking sensor and observation system add-on according to an exemplary
embodiment of the present invention, there is provided a bar with two parking
sensors and
a backup camera, and a monitor. The monitor, which may be an LCD monitor,
automatically activates to show distance and a clear view of the rear of the
vehicle when
the vehicle is put into reverse. The display shows digital distance indicators
of obstructions.
An audible display beeps faster as you get closer to an obstacle. The bar,
which includes
the sensors, camera and required operating circuitry, may be a chrome
waterproof and
5
CA 02684783 2009-11-06
dustproof housing. The bar is electronically coupled to the vehicle by a
single hookup
connection at the vehicle's reverse lamp.
In a parking sensor system add-on according to an exemplary embodiment of the
present invention, there is provided a bar with three parking sensors, and a
buzzer. The
parking sensors give full range detection up to six feet behind the vehicle,
for example.
The system automatically activates when the vehicle is put into reverse gear.
The buzzer
beeps faster as you get closer to an obstacle. The external structure of the
bar is essentially
the same as that of the parking sensor and observation system. The bar is also
electronically coupled to the vehicle by a single hookup connection at the
vehicle's reverse
lamp. This system additionally includes an extension cable to connect to the
buzzer
mounted inside the vehicle.
Both of the above-described systems are configured such that they can be
installed
in any vehicle by a consumer. The systems' bars can be mounted on either the
front or rear
bumpers/plates of a vehicle. The bar's dimensions may be exactly as wide as a
standard
United States license plate, and the bar can be configured such that it does
not extend
downward passed the plate, since this could cause it not to fit many vehicles.
It is to be
understood that when the bar is mounted to a vehicle's license plate, it
should in most cases,
not restrict parts of the plate that legal authorities wish to see. In doing
this, the bar is legal
in most of the United States. If, however, the bar were to restrict required
viewing portions
of the license plate, or if such mounting is not feasible or if a user desires
a different
viewing/sensing angle, the mounting brackets enable mounting below the plate,
directly to
the bumper or under the bumper.
