Part of the three car safety technologies goal is that by the year 2020, nobody shall be seriously injured or killed in a new Volvo. The Pedestrian Air Bag will come as a standard in the upcoming Volvo V40 sports wagon. Let us see how it works.
The pedestrian airbag system is active when the Volvo V40 is moving roughly between 20 to 50 km/h. Volvo indicates that most vehicle-pedestrian collisions happen when the car is moving up to 40 km/h. When an accident does happen, the system deploys fast, as in hundredths of a second.
Sensors throughout the front of the Volvo vehicle will transmit any impact to the pedestrian airbag system’s control unit, which will determine if it’s a pedestrian, for example, a human leg or not.
If it is indeed a human leg, the rear of the hood is blown open while, simultaneously, an airbag rapidly inflates to cover the Volvo vehicle’s lower windshield and the framing A-pillar.
The now-raised hood provides a crumple zone which is to cushion the struck pedestrian from the vehicle’s underlying hard chassis and engine. According to Volvo, these three areas can cause the most serious head injuries in vehicle-pedestrian collisions.
