Abstract

The accuracy of determination of a possibility of collision of a vehicle with an object is enhanced without the shortening of a period for detection of the object by an object detecting apparatus. A collision-possibility determining device determines the presence or absence of a possibility of collision of the vehicle with the obstacle by comparing a future locus of movement of the obstacle determined by an obstacle locus determining device based on an output from a radar device, with a future locus of movement of the vehicle determined by a vehicle locus determining apparatus based on outputs from wheel speed sensors and a yaw rate sensor. The period of the detection conducted by the radar device providing data about the obstacle to the obstacle locus determining apparatus is 100 msec, but the obstacle locus determining apparatus, the vehicle locus determining apparatus and the collision-possibility determining apparatus carry out the determination of the possibility of collision at a determination period shorter than the detection period of 100 msec. Thus, it is possible to carry out the determination of the possibility of collision at the shorter determination period without use of a large-sized and expensive radar device, thereby enhancing the determination accuracy.
