The sensor (20) is located in a front portion of a vehicle for measuring a collision state quantity correlating with a collision load generated in a collision of a colliding body with the vehicle. The determination circuit (40) determines whether the colliding body is a pedestrian based on the measured collision state quantity. The sensor (20) is located on an upper half region of a front end face of the bumper reinforcement member (12). Thus, accuracy of discriminating the pedestrian from other objects can be improved.
CROSS-REFERENCE TO RELATED APPLICATIONS This application is a National Stage of International application No. PCT/JP2006/306790, filed Mar. 24, 2006 and published in English as WO 2006/106897 A1 on Oct. 12, 2006. This application claims the benefit of JP 2005-104940, filed Mar. 31, 2005. The disclosure(s) of the above applications are incorporated herein by reference.
TECHNICAL FIELD The present invention relates to a colliding object determination device and a collision information detector for vehicle. In particular, the present invention relates to a device capable of properly detecting a collision of a pedestrian with a bumper.
BACKGROUND ART There has been a variety of collision detection sensors mounted to a bumper of a vehicle for detecting a collision of a colliding body such as a pedestrian based on a collision load of the colliding body or information associated with the collision load.
DISCLOSURE OF THE INVENTION It is an object of the present invention to provide a device capable of accurately discriminating a pedestrian from a lightweight object by using a simple device structure.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic perspective plan view showing a front portion of a vehicle according to an example embodiment of the present invention;
BEST MODES FOR CARRYING OUT THE INVENTION Referring to FIG. 1, a front portion of a vehicle according to an example embodiment of the present invention is illustrated. In this example embodiment, the present invention is applied to pedestrian detection. The front portion of the vehicle has a bumper cover 10, a bumper absorber 11, a bumper reinforcement member 12, side members 13, vehicle wheels 14, an optical fiber sensor 20, a load transmission plate 21, a sensor circuit 22, a wiring 23, a vehicle speed sensor 30, a wiring 31, a control section 40, a pedestrian protection device 50, a wiring 51, and the like. The optical fiber sensor 20, the load transmission plate 21 and the sensor circuit 22 constitute a collision load sensor (leak optical fiber sensor) for measuring a collision state quantity. A signal of a light amount measured by the sensor circuit 22 correlates with a collision load and is output to the control section 40 through the wiring 23. The vehicle speed sensor 30 measures rotation speed of the vehicle wheel 14. The signal of the measured vehicle speed is output to the control section 40 through the wiring 31. The pedestrian protection device 50 is a known pedestrian air bag device or a known hood lifting mechanism, for example. The control section 40 performs calculation with the input signals to determine whether a colliding body is a pedestrian. If the control section 40 determines that the colliding body is a pedestrian, the control section 40 operates the protection device 50 to protect the pedestrian.
