Abstract
An apparatus is disclosed for the automatic detection of dangerous objects in the left and right hand sides of a vehicle and in its back space which includes ultrasound transmitters (4) activated by generators (6) with a defined angle of radiation emitting ultrasound waves continuously, pulsed or modulated. Ultrasound receivers (14) are connected to an analyser for determination of intensity, speed of change, Doppler frequency change and the angle of fall of the received signal which determines the road situation. Dangerous objects are detected to the left and right of the driver and an alarm or signal is then given to the driver.
Description
VEHICLE ALARM SYSTEM
FIELD AND BACKGROUND OF THE INVENTION
The present invention relates to the field of technical vision for
objects detection, and, more particularly to systems for providing an alarm
when a vehicle is present in the dead zone of driver's view (Fig. 1) at the
left or right side of the vehicle, especially when the driver tries to move to
one side or the other, as when changing lanes.
SUMMARY OF THE INVENTION
According to the present invention, there is provided an apparatus
for the automatic detection of dangerous objects in the left and right sides
of vehicle and in its back space comprising: ultrasound transmitters (4)
activated by generators (6) with defined angle of radiation emitting
ultrasound waves continuously or pulsed or modulated; ultrasound receivers
(14) connected to an analog or digital analyzer for determination of
intensity, speed of change, Doppler's frequency change and angle of fall
of the received signal that determines road situation; amplifiers (16), signal
analyzer (18) includes time and frequency discriminators for speed and
distance determination, received returned signal from amplifiers and
standard signal from generator, control and signal from amplifiers and
standard signal from generator, control and calculation unit with condition
inputs like vehicle speed (10) and turn signal (12), commutation unit, alarm
or display unit for communication with driver, communication to other vehicle systems that detects dangerous objects presence into the pre-defined
area limited by lines of driver's direct view, borders of left and right
adjacent lines of traffic and predetermined distance back and provides
alarm or signalization to vehicle driver.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention is herein described, by way of example only, with
reference to the accompanying drawings, wherein:
Fig. 1 contains basic drawing of driver's field of view where αl is
a front view, α2 - view through left side mirror, α3 - view through right
side mirror, α4 - panorama mirror view, βl and β2 angles defining "dead
area" of drivers view. R and L are areas where detection of another
vehicle is needed. Those areas includes two lines (in the left and right
sides) limited by αl angle lines forward and same distance back from
vehicle (about 10-15 meters). Dashed line shows dangerous object may
occur in those areas.
Fig. 2 shows functional division of dangerous places on the left and
right sides. Distance A is comparable with vehicle length. Distance B is
additional length that dangerous object may arrive from.
Fig. 3 presents a basic embodiment of the apparatus, according to
the present invention which includes: radiation sources (4), radiation
receivers (14), amplifiers (16), signal analyzer (18), control and calculation
unit (8) with conditions inputs turn signal (12) and vehicle state of moving
(10), terminals (20) like computer interface, alarm and/or signalization.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Fig. 1 presents the borders of vehicle driver's view. Direct view
angle αl in addition with back view throw the left side mirror α2, back
view through right side mirror α3 and back view through panorama mirror
α4 remains open space in angle β l in left β2 in right side of drawing
vehicle. Non detected vehicle may appear in dead area. Danger state
occurs when driver tries to move to the left or right path of the road for
overcoming preceding low speed vehicle or any object on the left or right.
An accident may occur. For prevention of accident driver must have alarm
when another vehicle is moving in the dead area or comes near for
overcame his own vehicle.
An object of the present invention is to provide appropriate solutions
for detection of a vehicle appeared in the dead field of drivers view or in
every place in the right or left side and in questionable areas back of them.
Proposed problem solution based on ultrasound location of the dangerous
area R and L defined on Figs. 1 and 2. The ultrasound waves emitted
from transmitters 4 to the dangerous area are reflected back from the
overtake or moving parallel vehicle 2 and receiver 14. Amplified by
amplifiers 16 signal goes to signal analyzer 18 for place determination of
place and speed of vehicle in this area. Control and calculation unit 8
takes into account a number of useful signals like its own speed and state
of turn signal. The proposed system is preferably activated if two
conditions are presented: vehicle moves (speed signal 10) and driver
intends to change line left or right (turn signal 12), but may also be
activated continuously without regard to the turn signal 12 being activated.
When the vehicle is stationary it may be desirable to increase the zone of
hazard in order to take into account the greater differential speed between
the stationary vehicle and the nearby moving vehicles. In the terminals set
computer interface is available for communication with more complete and
complicated systems of vehicle electronics. Other terminals are different
systems of alarming and signalization.
In a preferred embodiment, the apparatus activates if only two
conditions are present: speed of vehicle is not equal to zero - vehicle
moves: turn signal is turned on indicating that the driver intends to move
left or right.
There is a difference among distances A and B. An object in areas
R and L into the region A is always dangerous. Vehicle in region B is
dangerous only if distance among the two vehicles decreases. An
apparatus actions defined for those two regions is different.
For regions L and R on distance A alarm or signalization will be
activated only if an overcoming vehicle will be detected in those areas.
For regions L and R on distance B alarm or signalization will be
activated in case when the speed of the detected vehicle is more than the
detector's carrier speed. The negative or positive difference of speed can
be defined by use of Doppler Effect.
While the invention has been described with respect to a limited
number of embodiments, it will be appreciated that many variations,
modifications and other applications of the invention may be made.
