Title: Collision determination apparatus
Inventor: NANAMI TAKESHI
IPC: G08G1/16
Filed: 2008-07-04
Abstract: <P>PROBLEM TO BE SOLVED: To provide a collision determination apparatus capable of suppressing generation of an unnecessary warning which gives troublesomeness to a driver.  <P>SOLUTION: The collision determination apparatus 1 computes a danger degree of collision of a previous vehicle with a driver's own vehicle using a previous vehicle information and own-vehicle information and, when the danger degree of collision is a predetermined threshold value or higher, determines it to be in a high danger. With the collision determination apparatus, when it is determined that a large intersection is ahead of the own vehicle from information of intersections acquired by a car navigation system 10, an infrastructure information receiver 11 or an image processor ECU13, a collision determination ECU15 changes a threshold value, which is a criterion for determining a danger degree of collision, to be a larger value. The danger degree of collision of the previous vehicle with the own vehicle is determined based on the threshold value changed in this way. Accordingly, in passing through an intersection while overtaking the previous vehicle attempting to turn the right or left, it is hard to send a notice that the danger degree of collision is high.  <P>COPYRIGHT: (C)2010,JPO&INPIT
