Forward collision avoidance systems use sensors to decide if vehicle is in danger of colliding with an object in its path. The system measures where cars, pedestrians, or objects are in proximity to the vehicle.
When the system detects a collision with an object, it will take actions such as warning the driver, pre-charging the vehicle’s braking system, and taking over the steering in some instances.
When a collision is unavoidable, some systems can bring the vehicle to a complete stop to minimize the damage. The system will also provide the driver and passengers with other measures to ensure their safety and reduce their physical harm. These include tightening their safety belts, closing the sunroof, and preparing the vehicle’s airbag for deployment.
