Abstract
A collision prediction ECU of a collision prediction apparatus estimates a state of presence of a detected front obstacle. At this time, the collision prediction ECU estimates the state of presence on the basis of road shape data supplied from a navigation ECU of a navigation apparatus. Further, the collision prediction ECU checks and corrects the calculated road gradient value. At this time, the collision prediction ECU corrects the gradient value on the basis of road gradient data supplied from the navigation ECU. Further, the collision prediction ECU changes a collision avoidance time on the basis of travel environment data supplied from the navigation ECU. Moreover, the collision prediction ECU obtains an ETC gate pass-through signal from the navigation ECU and determines whether the vehicle is passing through the gate. The collision prediction apparatus performs collation prediction on the basis of the corrected values.

17. A collision prediction apparatus mounted on a vehicle, the collision prediction apparatus comprising front obstacle detection means for detecting a front obstacle present on a route of travel of the vehicle and adapted to predictively determine whether the vehicle will collide with the detected front obstacle as a result of traveling of the vehicle, the collision prediction apparatus further comprising:
-
travel environment information acquisition means for acquiring travel environment information regarding a travel environment of the vehicle from a navigation apparatus mounted on the vehicle;
parameter value detection means for detecting a parameter value representing a state of traveling of the vehicle;
predictive collision determination means for comparing the parameter value detected by the parameter value detection means and a predetermined collision determination reference value used for predictive determination of a collision of the vehicle with the front obstacle, and predictively determining that the vehicle will collide with the front obstacle when the parameter value reaches the predetermined collision determination reference value; and
changing means for changing the predetermined collision determination reference value on the basis of the travel environment information acquired by the travel environment information acquisition means. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
