Abstract
A pedestrian collision detection device is obtained that is capable of improving pedestrian detection performance in the vicinity of a bumper corner portion. A pedestrian collision detection device includes a chamber member disposed with pressure detectors, and an ECU is connected to the pressure detectors. Terminal portions of the chamber member are wrapped around so as to cover vehicle width direction outside end faces of bumper reinforcement at bumper corner portion sides. When a load of a specific value or greater is input to the terminal portions of the chamber member from a bumper cover side during a collision, the terminal portions obtain a reactive force from the bumper reinforcement and undergo compression deformation towards the vehicle width direction inside, and the pressure inside a pressure chamber of the chamber member changes.
