Driving assist system for vehicle
First Claim
1. A driving assist system for a vehicle, comprisinga map data memory device to memorize map data;
- an inter-vehicle communication device to transmit and receive information between an own vehicle and another vehicle;
a mapping device to locate another vehicle on the map data that the own vehicle has in said map memory device, location of another vehicle being identified based on information with respect to another vehicle that is obtained by said inter-vehicle communication device;
an another-vehicle intersection detecting device to detect an intersection that is located on a traveling path of another vehicle, the traveling path of another vehicle being predicted based on the information with respect to another vehicle that is obtained by said inter-vehicle communication device;
an own-vehicle intersection detecting device to detect an intersection that is located in front of the own vehicle;
a collision-intersection identifying device to identify an intersection that is identical to each other as a possible collision intersection by comparing the intersections detected by said another-vehicle intersection detecting device and said own-vehicle intersection detecting device;
an information providing device to conduct an information provision based on calculation of an arriving time of another vehicle to reach the possible collision intersection identified by said collision-intersection identifying device; and
a collision pattern predicting device to predict a collision pattern between the own vehicle and another vehicle at the possible collision intersection, and said mapping device is configured such that another vehicle located thereby is limited to the one that has the collision pattern predicted by said collision pattern predicting device.

Abstract
A mapping block locates the own vehicle and another vehicle on a map DB. Another-vehicle intersection detecting block detects intersections located on a traveling path of another vehicle. An own-vehicle intersection detecting block detects intersections located in front of the own vehicle. A collision-intersection identifying block identifies an intersection that is identical to each other as the possible collision intersection by comparing the intersections detected. An information providing block conducts information provision based on calculations of an arriving time of another vehicle by using a distance to the possible collision intersection and a vehicle speed. Accordingly, the collision possibility with another vehicle can be accurately determined.
