<p><P>PROBLEM TO BE SOLVED: To provide a collision prediction apparatus accurately recognizing a front obstacle highly likely to collide with the own vehicle with improved accuracy in collision prediction determination. <P>SOLUTION: A collision prediction ECU 11 of this collision prediction apparatus 10 estimates a state of presence of the detected front obstacle. At this time, the ECU 11 estimates the state of presence on the basis of road shape data supplied from a navigation ECU 21 of a navigation apparatus 20. Further, the ECU 11 checks and corrects the calculated road gradient value. At this time, the ECU 11 corrects the gradient value on the basis of road gradient data supplied from the ECU 21. Further, the ECU 11 changes a collision avoidance time Tc on the basis of travel environment data supplied from the ECU 21. Moreover, the ECU 11 obtains an ETC gate pass-through signal from the ECU 21 and determines whether or not the vehicle is passing through the gate. Then, the ECU 11 predicts collision on the basis of the corrected values. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
