The accident prevention system warns the driver about a possible collision in front, and then takes various measures to increase the safety of the car if the driver does not respond to a warning to prevent a collision. Tests have shown that these systems reduce the impact force by 40%.
The system of preventing the accident
The accident prevention systems use radar sensors, laser and / or image sensors for detection if the accident is inevitable. If the system detects a possible collision, it will warn the driver with a visual and / or sound signal to an impending accident. If the driver does not try to slow down the car or moves too fast to slow down in time, the safety system will tighten the seat belts and increase the pressure in the brake system to prepare the brakes for better performance. Some systems will take additional measures, such as closing the window and hatch, inflating air chambers in places, positioning in a passenger seat in a more vertical and safe position, and raising the head restraints of the seats.
Nissan introduced a system capable of detecting the car two cars in front to help prevent collisions. The system uses radar sensors that can detect the second car in front, expanding the radar range. When the system detects potential risks, informs the driver through the dashboard display, a sound warning and tightens the seat belt. This system is available on the 2014 Q50 infinity.
