<P>PROBLEM TO BE SOLVED: To achieve a collision detector capable of distinguishing the collision of a human from that of the other objects reliably and preventing erroneous detection. <P>SOLUTION: The collision detector 1 detects the intensity of heat rays radiated from a target to be detected that approaches or comes into contact with a vehicle 80 by a human detection sensor 30, outputs a first directional signal for indicating the direction of the presence of a target to be detected, based on the detected intensity, detects ultrasonic waves reflected by the target to be detected, and outputs a second directional signal for indicating the direction of the presence of the target to be detected, based on the detection result. A physical value sensor 27 detects the application of shock to a vehicle, and outputs a shock signal for indicating the application of shock to the vehicle based on the detection result. Then, it is determined that the difference between the first and second directional signals is within a first range, and a collision signal for indicating the collision of a human to the vehicle is output by an ECU 21 when the collision signal is output. <P>COPYRIGHT: (C)2008,JPO&INPIT |
