CAR LOT - DETROIT.
General Motors (GM) introduced a system of preventing collisions on the
GMC SUV Terrain, which will be launched next year. The company's claim, this is the first system used in the automotive industry. The system uses only one camera.
Besides functioning to prevent crashing into a car that was or gliding slowly in front, also prevents knocking or grazed when moving point.
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. Then the system will give warning with sound and images.
Digital Image
"Digital image sensor used in this system, the concept is the same as the image of a cell phone that sent the computer. Therefore, the use of the camera system is more easily on the vehicle, "says Raymond Kiefer, Collision Prevention System 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 of: green, for collisions at the front and the icon for detect displacement path. Such as warning lights flashing red warning crashed into 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, in a way warned the driver if the driver following 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 Works?
Forward 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.
By changing 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, example by snow or mud.
Speed
In addition to overseeing the 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.
"
GM is committed to providing the initial protection, during and after the collision. The best scenario is to avoid a collision. This technology 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.
