Driving support device, driving support method and driving support program
First Claim
1. A driving support device comprising:
- an acceleration gear ratio obtaining unit that acquires information pertaining to a first zone set ahead of a host vehicle and a second zone farther ahead than the first zone, wherein based on the information, if a distance between an end point of the first zone and a start point of the second zone is shorter than a distance within which the host vehicle can be slowed at a predetermined deceleration from a first target vehicle speed for traveling the first zone to a second target vehicle speed for traveling the second zone, a second acceleration gear ratio is acquired for accelerating the host vehicle in a second acceleration zone following the second zone; and
a gear ratio control unit that sets the gear ratio of the host vehicle to the second acceleration gear ratio in a first deceleration zone for slowing the host vehicle before reaching the first zone.

Abstract
Information pertaining to a first zone set ahead of a host vehicle and a second zone farther ahead than the first zone is acquired. Based on the information, if a distance between an end point of the first zone and a start point of the second zone is shorter than a distance within which the host vehicle can be slowed at a predetermined deceleration to a second target vehicle speed for traveling the second zone at the start point of the second zone, a second acceleration gear ratio is acquired for accelerating the host vehicle in a second acceleration zone following the second zone. The gear ratio of the host vehicle is set to the second acceleration gear ratio in a first deceleration zone for slowing the host vehicle before reaching the first zone.

4. A driving support program performing in a computer the functions of:
-
acquiring information pertaining to a first zone set ahead of a host vehicle and a second zone farther ahead than the first zone, wherein based on the information, if a distance between an end point of the first zone and a start point of the second zone is shorter than a distance within which the host vehicle can be slowed at a predetermined deceleration from a first target vehicle speed for traveling the first zone to a second target vehicle speed for traveling the second zone at the start point of the second zone, a second acceleration gear ratio is acquired for accelerating the host vehicle in a second acceleration zone following the second zone; and setting the gear ratio of the host vehicle to the second acceleration gear ratio in a first deceleration zone for slowing the host vehicle before reaching the first zone.
