DETROIT, - "GM is committed to providing the initial protection, during and after the collision. The best scenario is to avoid tabarakan.Teknologi is designed to help drivers avoid crashing, "said Gay Kent, Executive Direcytor Vehicle Safety and crashworthiness of GM on the use of this collision prevention.
GMC system uses a
high resolution digital camera mounted on the
front of the rearview mirror to see the form of vehicles and road markings. The next system, will give a warning with the sounds and images.
General Motors (GM) introduced a system of preventing collisions on the
GMC Terrain SUV to be launched next year. The company's claim, this is the first system used in the automotive industry. The system uses only one camera.
In addition to use to avoid crashing cars that are or gliding slowly in front, also prevents knocking or grazed when moving point.
Motorists are being warned to be on the back of another vehicle and the distance is too close. Voice warning also appears if the vehicle is moving lane without activating the turn signal (the indicator light turns).
Digital Image
According to the National Automotive Sampling System, menabrakan the rear 28 percent of the nearly 6 million insinden accidents that occur each year based on police reports. Meanwhile, the
National Highway Traffic Safety Administration (
NTSHA), said rear collisions generally occur because attention is not focused on the road. Hence, the
Insurance Institute for Highway Safety (
IIHS) rate, GMC collision warning system was considered very helpful to reduce accidents.
"Digital image sensor used in this system, the concept is the same as the image of a cell phone that sent the computer. That's why the use of the camera system is more easily on kendaraa, "beber Raymond Kiefer, PencegahTabrakan Systems Technical Fellow, GM.
"Combined with the algorithm of digital camera images, enabling us to calculate the time of the collision," he added.
Impressions reminder consists, for a collision in front of the green and the icon for detect perpindah jalaur. Are like the warning lights flashing red warning hit the vehicle in front, warning lanes using the orange icon with the sound of bells.
Warning system is working at a speed of 40 km / h, the driver warned if they follow the vehicle ahead too closely. Also warned of the possibility of going to hit. If the predicted collision is unavoidable, the vehicle will activate the brakes help drivers slow down and stop the vehicle more quickly.
How it WorksForward collision warning software works by examining images taken of - 14 "frames" per second - to determine the shape of the vehicle. Furthermore, vehicles are detected, checked at every turn of the picture frame.
Demgam change the size, the possibility of a collision time occurs can be calculated. The system also uses other parameters, namely speed, change direction and movement of the gas and brake pedals.
To be used on condition pernglihatan different, the system combines four separate Exposure to creating high resolution images and then analyzed. This method is very useful at night when close exposure is necessary to clarify the picture. While the exposure is much used to detect the shape and texture.
At night, the target is determined by looking at a pair of light that move in tandem, in this case using the rear lights. The system works as long as the camera eye is not obstructed, misalya by snow or mud.
SpeedIn addition to pelototi vehicle in front, the picture also looked at markers-markers to determine a warning when moving point. At a speed of 56 km / h, a warning icon moving point - solid green that mark active or working.
If the vehicle out of lanes without turn signal switch, turn lights, flashing at once issued a beep sound.
