The system has one objective: to keep the pedestrian as safe as possible in the event of a collision. Sensors in the front bumper of the car are always active and alert, waiting to inflate the airbag in less than a few hundredths of a second. When fully deployed, the airbag covers the windshield wiper area and the bottom of the A-pillars, the two most common places that pedestrians strike their heads during a collision. The system is only active from about 12 mph to 30 mph, as Volvo calculates that 75 percent of pedestrian accidents occur at around 25 mph.
This system acts in congruence with Volvo’s full auto brake pedestrian detection setup, which debuted in 2010, and activates the brakes of the car if pedestrians are detected.
To facilitate the deployment of the pedestrian airbag, a pyrotechnical release mechanism is used at the back end of the hood, and when deployed raises the hood by ten centimeters. This serves a double purpose, as now the hood also has some absorption properties and added angle, to lessen the severity of an impact.
So if you are a constant jay-walker, just hope that the next car to hit you is a Volvo.
This new technology will debut on the Volvo V40.
