The present colliding obstacle detection apparatus comprises a pedestrian bumper 20, which is supported below a front bumper 50 of the vehicle by a body of the vehicle, at least one collision detector 1,200, which is located on the pedestrian bumper and a control circuit 2, 3 which determines whether the collision has actually occurred based on a detection signal outputted by the at least one collision detector. The front end of the pedestrian bumper vertically aligns with or extending ahead of that of the front bumper. The at least one collision detector detects one of a collision of the pedestrian bumper with an obstacle, and a presence of the obstacle in a close proximity to the pedestrian bumper. When the control circuit determines that the collision has actually occurred, the circuit activates a colliding obstacle protector 4 for protecting the obstacle, especially a pedestrian. The obstacle protector may be a hood air bag or a hood lifting mechanism. Preferably the at least one collision detector may include an impedance sensor having a coil, a capacitance sensor, a colliding load sensor and/or an ultrasonic sensor. |
