HOST-VEHICLE RISK ACQUISITION
First Claim
1. A host-vehicle risk acquisition device comprising:
- a host-vehicle sensor that detects a travel state of a host vehicle;
a host-vehicle path acquisition portion that acquires a path of a host-vehicle;
an obstacle path acquisition portion that acquires a plurality of paths of an obstacle existing around the host-vehicle;
a collision risk acquisition portion that 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 detected by the host-vehicle sensor based on the path of the host-vehicle and the plurality of paths of the obstacle; and
an offset risk acquisition portion that acquires an offset risk, which is a collision risk between the host-vehicle and the obstacle in an offset travel state, which is obtained by changing the travel state of the host-vehicle detected by the host-vehicle sensor by adding an offset value to the current travel state.

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.

9. A host-vehicle risk acquisition method comprising:
-
detecting a travel state of a host-vehicle; calculating an offset travel state of the host-vehicle which is offset from the host-vehicle travel state; calculating a host-vehicle offset possible path based on the host-vehicle offset travel state; calculating a plurality of possible paths of an obstacle existing around the host-vehicle; calculating 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. - View Dependent Claims (10, 11)

12. A host-vehicle risk acquisition device comprising:
-
a host-vehicle sensor for detecting a travel state of a host vehicle; host-vehicle path acquisition means for acquiring a path of an host-vehicle; obstacle path acquisition means for acquiring a plurality of paths of an obstacle existing around the host-vehicle; collision risk acquisition means for acquiring 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 detected by the host-vehicle sensor based on the path of the host-vehicle and the plurality of paths of the obstacle; and offset risk acquisition means for acquiring an offset risk, which is a collision risk between the host-vehicle and the obstacle in an offset travel state, which is obtained by changing the travel state of the host-vehicle detected by the host-vehicle sensor by adding an offset value to the current travel state.
