Driving support device, driving support method and driving support program
First Claim
1. A driving support device for obtaining and setting acceleration gear ratios that facilitate a first acceleration of a host vehicle after the host vehicle has decelerated into a first zone, and that facilitate a second acceleration of the host vehicle when the host vehicle must decelerate into a second zone following the first acceleration comprising:
- an acceleration gear ratio obtaining unit that acquires a first acceleration gear ratio for accelerating a host vehicle in a first acceleration zone following the first zone, and that acquires a second acceleration gear ratio for accelerating the host vehicle in a second acceleration zone following the second zone; and
a gear ratio control unit that executes a control for setting the gear ratio of the host vehicle to the first acceleration gear ratio when the host vehicle is in a first deceleration zone in order to decelerate the host vehicle before entering the first zone, and that further executes a control, while the host vehicle is traveling in the first acceleration gear ratio, for setting the gear ratio of the host vehicle to the second acceleration gear ratio when the host vehicle must decelerate before entering the second zone.

Abstract
A first acceleration gear ratio is acquired for accelerating a host vehicle in a first acceleration zone following a first zone ahead of the host vehicle, and a second acceleration gear ratio is acquired for accelerating the host vehicle in a second acceleration zone following a second zone ahead of the first zone. A control is executed to set the gear ratio of the host vehicle to the first acceleration gear ratio in a first deceleration zone in order to decelerate the host vehicle before entering the first zone. A control is executed to set the gear ratio of the host vehicle to the second acceleration gear ratio when the host vehicle must decelerate with respect to the second zone while traveling in the first acceleration gear ratio.

5. A driving support method for obtaining and setting acceleration gear ratios that facilitate a first acceleration of a host vehicle after the host vehicle has decelerated into a first zone, and that facilitate a second acceleration of the host vehicle when the host vehicle must decelerate into a second zone following the first acceleration, said method comprising the steps of:
-
an acceleration gear ratio obtaining unit acquiring a first acceleration gear ratio for accelerating a host vehicle in a first acceleration zone following the first zone; the acceleration gear ratio obtaining unit acquiring a second acceleration gear ratio for accelerating the host vehicle in a second acceleration zone following the second zone; a gear ratio control unit executing a control for setting the gear ratio of a transmission of the host vehicle to the first acceleration gear ratio when the host vehicle is in a first deceleration zone in order to decelerate the host vehicle before entering the first zone; and the gear ratio control unit executing a control for setting the gear ratio of the transmission of the host vehicle to the second acceleration gear ratio when the host vehicle must decelerate with respect to the second zone while traveling in the first acceleration gear ratio.

6. A non-transitory, computer-readable medium encoded with a driving support program for obtaining and setting acceleration gear ratios that facilitate a first acceleration of a host vehicle after the host vehicle has decelerated into a first zone, and that facilitate a second acceleration of the host vehicle when the host vehicle must decelerate into a second zone following the first acceleration, said driving support program causing a computer to execute the steps of:
-
acquiring a first acceleration gear ratio for accelerating a host vehicle in a first acceleration zone following the first zone; acquiring a second acceleration gear ratio for accelerating the host vehicle in a second acceleration zone following the second zone; executing a control for setting the gear ratio of the host vehicle to the first acceleration gear ratio when the host vehicle is in a first deceleration zone in order to decelerate the host vehicle before entering the first zone; and executing a control for setting the gear ratio of the host vehicle to the second acceleration gear ratio when the host vehicle must decelerate with respect to the second zone while traveling in the first acceleration gear ratio.
