Driving support device and driving support method
First Claim
1. A driving support device that performs driving support for avoiding collision between a vehicle and a moving object, the driving support device comprising:
- circuitry configured to;
predict a first time required for the vehicle to arrive at an intersection point in a traveling direction, the intersection point being a point at which the vehicle and the moving object intersect in the traveling direction of the vehicle and in a direction intersecting with the traveling direction;
predict a second time required for the moving object to arrive at the intersection point in the direction intersecting with the traveling direction;
determine whether driving support is to be performed in the vehicle by applying the predicted first and second times to a pre-set map; and
control driving support in the vehicle if driving support is determined to be performed in the vehicle,wherein a first area, for which driving support is determined unnecessary, and a second area, for which driving support is determined necessary, are set in the map, andwherein driving support is determined to be performed in the vehicle if an intersecting point between the first time and the second time is present in the second area, the intersecting point representing a relation between the first time and the second time.

Abstract
A driving support device and a driving support method, which can appropriately determine whether driving support is necessary and perform effective driving support, are provided. A driving support device calculates TTC, which is a time required for the vehicle to arrive at an intersection point at which the vehicle and a moving object intersect in the traveling direction of the vehicle and in a direction intersecting with the traveling direction, and TTV required for the moving object to arrive at the intersection point, and performs driving support in the vehicle based on the relative relation between TTC and TTV.

4. A driving support method for avoiding collision between a vehicle and a moving object, the driving support method comprising,
predicting a first time required for the vehicle to arrive at an intersection point in a traveling direction, the intersection point being a point at which the vehicle and the moving object intersect in the traveling direction of the vehicle and in a direction intersecting with the traveling direction; -
predicting a second time required for the moving object to arrive at the intersection point in the direction intersecting with the traveling direction; determining whether driving support is to be performed in the vehicle by applying the first and second times to a pre-set map; and controlling driving support in the vehicle if performing the driving support in the vehicle is determined, wherein a first area, for which driving support is determined unnecessary, and a second area, for which driving support is determined necessary, are set in the map, and wherein driving support is determined to be performed in the vehicle if an intersecting point between the first time and the second time is present in the second area, the intersecting point representing a relation between the first time and the second time. - View Dependent Claims (5)
