DRIVING-ASSISTANCE DEVICE AND DRIVING-ASSISTANCE METHOD
First Claim
1. A driving-assistance device in which, when a three-dimensional object is present on a course of a host vehicle, driving assistance for avoiding a collision between the host vehicle and the three-dimensional object is implemented on a condition that an unavoidable three-dimensional object is present in a predetermined range including the course, the driving-assistance device comprising:
- a setting unit configured to set the predetermined range in the vicinity of the host vehicle,wherein the setting unit sets a degree of width of the predetermined range in accordance with a predetermined rule which is set in advance on the basis of at least one of a moving state and a type of the three-dimensional object, andwherein the setting unit sets the degree of width to become smaller as an absolute movement velocity of the three-dimensional object becomes higher.

Abstract
A driving-assistance device 100 makes it a condition for implementing driving assistance for collision avoidance that a normal travel area AR is set in the vicinity of a host vehicle, and that an unavoidable obstacle D is present within the normal travel area AR. Particularly, in the driving-assistance device 100, a degree of width W of the normal travel area AR is set in accordance with a rule based on a type or the like of the obstacle D. For this reason, a timing at which a collision with the obstacle D cannot be avoided within the normal travel area AR (timing at which a condition for implementing driving assistance for collision avoidance is established) becomes variable in accordance with the type or the like of the obstacle D. Thus, it is possible to implement the driving assistance for collision avoidance more appropriate to a driver'"'"'s intuition.

10. A driving-assistance method in which, when a three-dimensional object is present on a course of a host vehicle, driving assistance for avoiding a collision between the host vehicle and the three-dimensional object is implemented on a condition that an unavoidable three-dimensional object is present in a predetermined range including the course, the driving-assistance method comprising:
-
a setting step of setting the predetermined range in the vicinity of the host vehicle, wherein in the setting step, a degree of width of the predetermined range is set in accordance with a rule which is set in advance on the basis of at least one of a moving state and a type of the three-dimensional object, and wherein in the setting step, the degree of width is set to become smaller as an absolute movement velocity of the three-dimensional object becomes higher.
