Ford is adding in its upcoming models, Pre-Collision Assist with Pedestrian Detection – to reduce the severity of and, in some cases, even eliminate frontal collisions involving pedestrians using a combination of radar and camera sensing. Pre-Collision Assist with Pedestrian Detection will debut as available technology on the 2015 Ford Mondeo on sale in Europe this year. It will then roll out to other Ford and Lincoln products around the world.

Other available Ford driver-assist technologies include lane-keeping system with lane-keeping aid, Blind Spot Information System (BLIS®) with cross-traffic alert, adaptive cruise control and collision warning with brake support, and active park assist

FORD Pedestrian DetectionEngineers experiment with the pedestrian detection system on a test track.

Pre-Collision Assist with Pedestrian Detection uses radar and camera technology to scan the roadway ahead. The system uses two sensors: radar in the bumper and a camera on the windshield. The radar detects an object, and the camera can determine if it is a person crossing the road. The system processes information collected from a windshield-mounted camera and radar located near the bumper; it then checks the information against a database of pedestrian shapes to help distinguish people from typical roadside scenery and objects.

In daylight and clear weather conditions, the new technology may detect people in or near the road ahead, or pedestrians crossing the vehicle’s path. If a pedestrian is detected in front of the car and a collision is imminent, the driver first receives an audible and visual warning. Should the driver not respond, the system improves brake responsiveness by reducing the gap between brake pads and discs. If there is still no response from the driver, the brakes are applied automatically and vehicle speed is reduced.

While the new system may be especially helpful in unexpected situations, it does not replace the driver and has limitations including nighttime, low and harsh lighting conditions, vehicles moving in a different direction and certain weather conditions.

“This real-world testing was an important part of the development, because pedestrians in an urban setting can present a wide range of potential situations.We covered more than 300,000 miles on three continents that included a wide range of settings and situations.”
