Host-vehicle risk acquisition device and method
First Claim
1. A host-vehicle risk acquisition method comprising:
- detecting a travel state of a host-vehicle;
calculating using a processor an offset travel state of the host-vehicle which is offset from the host-vehicle travel state;
calculating using the processor a host-vehicle offset possible path based on the host-vehicle offset travel state, the host-vehicle offset possible path being an offset trajectory that the host-vehicle is able to travel;
calculating using the processor a plurality of possible paths of an obstacle existing around the host vehicle, the possible paths being paths in which the obstacle is capable of moving until a predetermined moving time elapses;
calculating using the processor an offset risk, which is a collision risk between the host-vehicle and the obstacle when the host-vehicle travels on the host-vehicle offset possible path, anddisplaying the host-vehicle offset possible path.

Abstract
A host-vehicle risk acquisition device includes a host-vehicle path acquisition portion that acquires a path of a host-vehicle, and an obstacle path acquisition portion that acquires a plurality of paths of an obstacle existing around the host-vehicle. A collision risk acquisition portion acquires an actual collision risk, which is a collision risk between the host-vehicle and the obstacle when the host-vehicle is in a travel state based on the path of the host-vehicle and the plurality of paths of the obstacle. An offset risk acquisition portion acquires an offset risk, which is a collision risk between the host-vehicle and the obstacle in an offset travel state, which is offset from the travel state of the host-vehicle.
