Automobile Pedestrian Collision Detection Sensor
Denso has developed a pedestrian collision detection sensor for the Pop-up Hood. The Pop-up Hood was designed to reduce pedestrian head injuries in a pedestrian/vehicle engine hood collision by creating a larger buffer space between the hood and hard components, including the engine, under the hood. When a pedestrian collides with the front bumper of a vehicle within a predetermined speed range, the pedestrian collision detection sensor sends the information to the airbag electric control unit to make the hood pop up at the moment of the frontal collision. The new sensor more precisely detects head-on collisions between vehicles and pedestrians, enabling the Pop-up Hood to operate more accurately.
