Ford is bringing the PreCollision Assist to United States in 2015. It helps avoid or lessen impact in car-to-car and car-to-pedestrian collisions. This system uses a combination of radar and video camera data to construct a more accurate image of the surroundings and apply the brakes in case the driver does not respond to warning.
The system is scanning the road ahead. The radar is very good at determining distance and closing speed to objects ahead. The video camera is good at classifying the objects. Information is fused together and if the car determines there is a possible or imminent collision, it will first warn the driver using audible sound and flashing light. The system will also prepare the brakes by bringing the pads closer to the rotor. If the driver does not respond to warnings and the collision is imminent, the system will apply full braking force automatically to help avoid or lessen the impact.
The PreCollision Assist is designed specifically to recognize and react to other vehicles and pedestrians. Ford engineers say that it’s not designed to avoid collisions with animals or other random objects, perhaps a piano falling off a truck. The system has been shown to successfully stop the vehicle from 40 km/hr (or 24.8 MPH).
Clearly, this system is meant to be used in crowded cities and highways.
