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.
