Description

DESCRIPTION
A CAMERA VIEW SYSTEM DETECTING BLIND SPOTS IN
TRAFFIC
The invention is a system for reducing the damage of traffic accidents and for turning accidents with injury into accidents with material damage and relates to a method for increasing angle of sight by transmitting the images acquired from cameras mounted on front and rear bumper of vehicles to certain locations inside the vehicle and for reducing the severity of accidents.
While there are precautions taken by the automotive manufacturers for reducing the number of traffic accidents in the state of the art, there are several patent and utility model applications regarding current problem. In said applications, solutions such as reducing death and injury rates due to traffic accidents by means of increasing safety belt usage, preventing accidents by means of preventing the headlights from disturbing the drivers on highways and urban areas by a system sensitive to headlights, and a device aiming to warn the drivers of the moving vehicles against possible crashes and to minimize the number and severity of accidents involving frontal collision are disclosed.
In accordance with the data acquired by taking into consideration the studies and expert reviews, it is seen that in various types of traffic accidents, depending on the collision speed, death risk increases from 10% to 70% in the conditions given below.
For pedestrians from 30 km/h to 50 km/h
In lateral collisions from 50 km/h to 70 km/h
In head-on collisions from 70 km/h to 90 km/h
The 20 km/h difference in speed may become an accident resulting in death. These results show the importance of speed.
The higher the velocity is in a collision, the higher the amount of mechanical (kinetic) energy that must be absorbed at the moment of crash. The velocity modifications which affect road safety are directly related to the change in kinetic energy which is generated at the moment of crash. The kinetic energy of a moving vehicle is directly proportional to the mass of the vehicle and to the square of its velocity. (ek=l/2m*v2) In high speeds, the velocity at the moment of crash is increased and thus, the force applied to the vehicle and the passengers is also increased. Therefore, it is much more probable for high speed to cause important losses.
In roads sectors, the speed limit of which variates between 25km/h and 120 km/h, there is a strong statistical correlation between speed and risk of crash. If the average speed is reduced in traffic, number of crashes and serious injuries is pretty much reduced; if the average speed is increased, number of crashes and serious injuries is generally increased. The formula stating the correlation between speed modifications and crash risk is given below.
CMF= (Va/Vb )X
CMF= Crash modification factor
Va: Average speed after speed change
Vt,: Average speed before speed change
X= 3.6 (Crashes involving death)
2.0 (Crashes involving injury)
1.0 (Crashes resulting in material damage)
4.5 (Deaths)
2.7 (Injuries)
It is seen that a 5% increase in average speed results in a 10% increase in crashes involving injury and a 20% increase in crashes involving death.
For instance;
For vehicle A travelling at 50 km/h (13.88 m/s);
Stopping distance: 10.4 meters
Braking distance: 16.4 meters Total stopping distance: 10.4+16.4=26.8 meters.
The distance Y (the distance between the driver and the front point of the vehicle): 2.2 meters (differs in accordance with the brand, model and type of the vehicle.)
In how many seconds does a vehicle speeding up from 0 km/h cover 2.2 meters?
Vf: 20 km h=5.55 m/s Vi: 0 Vf: 2.2 meters
Yf: 0
Although it differs in accordance with vehicle type and reflexes V=Vf-Vi=5.55-0=5.55 m/s Y=Yf-Yi=2.2-0=2.2 meters
T= Y/V = 2.2/5.55=0.396=0.4 seconds (approximately)
Distance covered by a vehicle travelling at 50 km/h = 13.88 m/s is Y=V*T=13.88*0.4=5.6 meter (approximately)
In this case, the stopping distance of the same vehicle: 26.8+5.6= 32.4 meter In this case,
• As the vehicle A will see the vehicle B which gets on the road later, the stopping distance will increase.
• Vehicle B will get on the way of vehicle A.
• Due to the fact that its stopping distance increases, the crash impact and speed of vehicle A to vehicle B will increase.
• If a crash occurs, the crashing point of vehicle A to vehicle B will be in a position which will do more harm to the people in vehicle B.
When we increase the angle of sight which is low in accordance with the seating point inside the vehicle by means of the cameras we place on front bumpers of vehicles, vehicle B will not get on the road because it sees vehicle A beforehand and even if it gets on the road, it will stop earlier as it sees vehicle A. In this case, vehicle A will continue safely or it chance of a maneuver will increase. If a crash occurs despite this, vehicle A will hit vehicle B from the front. This way, the damage in accidents will be reduced from death and injury to material damage. Possible crash scenarios depending on angle of sight are explained below with examples.

With the method according to the invention, it is aimed to increase angle of sight by transmitting the images acquired from cameras mounted on front and rear bumper of vehicles to certain locations inside the vehicle and to reduce the severity of accidents.
In the method according to the invention, in-vehicle angle of sight is increased by installing to the right and left side of front and rear bumpers four cameras with a 140 degree or above angle of sight, which provide image day and night, which have maximum angle of sight and which are impact resistant. The images received from these cameras are transmitted to displays mounted on several locations inside the car. These locations, for example locations on the inner section of vehicle side mirrors or the in-vehicle sections therein where there is a small glass, must be suitable for human ergonomics and vehicle designs. Depending on the OLED displays becoming widespread, in-vehicle camera applications will have a much aesthetical form.
Moreover, these displays may be united at the middle of the vehicle. However, instinctually, a human will have the urge to turn his/her head towards the direction where the danger, vehicle etc. is approaching from.
These cameras may transmit image to the displays continuously, or alternatively front cameras may be activated in forward movement and rear cameras may be activated in backward movement. Moreover, transmitting the image to the displays from the front cameras, the rear cameras or the right side and the left side cameras may be conducted by means of a signal or a button. These systems may be capable of both recording the images and transmitting the camera image to the display without recording. The next step will be adding a distance measuring equipment and a warning system along with cameras to the bumpers of the vehicles, calculating the distance and speed of vehicle A approaching vehicle B and notifying the movement of vehicle B by means of warning and alarm or stopping the movement of vehicle B. The camera view system detecting blind spots in traffic which is created in order to realize the object of the invention is illustrated in the attached figures, in which;
