Patent ID: 8670907

Claim:
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.
