context_page_description: A collision avoidance system, also known as a pre-crash system, forward collision warning system, or collision mitigation system, is an automobile safety system designed to prevent or reduce the severity of a collision. In its basic form, a forward collision warning system monitors a vehicle's speed, the speed of the vehicle in front of it, and the distance between the vehicles, so that it can provide a warning to the driver if the vehicles get too close, potentially helping to avoid a crash. Various technologies and sensors that are used include radar and sometimes laser and camera to detect an imminent crash. GPS sensors can detect fixed dangers such as approaching stop signs through a location database. Pedestrian detection can also be a feature of these types of systems.
  Collision avoidance system range from widespread systems mandatory in some countries, such as Autonomous Emergency Braking in the EU, agreements between automakers and safety officials to make crash avoidance systems eventually standard, such as in the United States, to research projects including some manufacturer specific devices.
context_section_description: 2010: "Front Assist" on the 2011 Volkswagen Touareg can brake the car to a stop in case of an emergency and tension the seat belts as a precautionary measure.
  2012: Volkswagen Golf Mk7 introduced a "Proactive Occupant Protection" that will close the windows and retract the safety belts to remove excess slack if the potential for a forward crash is detected. Multi-collision brake system (automatic post-collision braking system) to automatically brake the car after an accident in order to avoid a second collision. City emergency braking automatically activates brakes at low speeds in urban situations.
  2014: Volkswagen Passat (B8) introduces pedestrian recognition a part of the system. It uses a sensor fusion between a camera and the radar sensor. There is an "emergency assist" in case of a non-reacting driver, the car takes the control of the brakes and the steering until a complete stop. This is also found on the Volkswagen Golf Mk8.
