Abstract
An obstacle discrimination device for a vehicle includes an absorber arranged at a front surface of a bumper reinforce member in a bumper cover of the vehicle, a pressure detection unit, a vehicle velocity detection unit and an obstacle judgment unit. The absorber has therein at least one chamber, in which fluid is sealed. A pressure in the chamber which varies due to a collision of an obstacle with a bumper of the vehicle is detected by the pressure detection unit. A pedestrian is distinguished according to whether or nor the pressure exceeds a threshold value related to a velocity of the vehicle detected by the vehicle velocity detection unit.
