Colliding object determination device and collision information detector for vehicle

A colliding object determination device for a vehicle having a bumper reinforcement member, the colliding object determination device comprising:

• a sensor located in a front portion of the vehicle for measuring a collision state quantity correlating with a collision load generated in a collision of a colliding body with the vehicle;
• and
• a determination circuit for determining whether the colliding body is a pedestrian based on the measured collision state quantity, wherein
• the sensor is located on an upper half region of a front end face of the bumper reinforcement member,
• the sensor includes:
• an optical fiber that extends in a side-to-side direction of the vehicle in the front portion of the vehicle and that is deformed in the collision of the colliding body with the vehicle;
• a light-emitting circuit section that introduces light to the optical fiber;
• and
• a light-receiving circuit section that converts the light output from the optical fiber into an electric quantity.

• and
• a determination circuit for determining whether the colliding body is a pedestrian based on the measured collision state quantity, wherein the determination circuit determines a kind of the colliding body solely based on the collision load applied to an upper half region of a front end face of the bumper reinforcement member;
• wherein
• the sensor is located on a front end face of the bumper reinforcement member;
• and
• the vehicle includes a front bumper and a pedestrian bumper, which is located at the same fore-and-aft position as the front bumper or ahead of the front bumper at least at a time of the collision, the pedestrian bumper located under the front bumper.
