Abstract:
1. A driving support device, comprising: vehicle speed information obtaining unit that obtains a target vehicle speed “V accelerating speed ratio obtaining unit that obtains a necessary acceleration amount “a” for accelerating the vehicle from the target vehicle speed “V speed ratio control unit that sets a speed ratio of a transmission unit which transmits a drive force of a power unit to wheels of the vehicle to the accelerating speed ratio “Sa” before the vehicle reaches a start point “Rs” of the predetermined section; and deceleration control unit that reduces a speed of the vehicle to the target vehicle speed “V wherein a front section is set before the predetermined section, as the section in which the deceleration control by the deceleration control unit is performed before the vehicle reaches the predetermined section, wherein an acceleration section “Za” from an end point “Re” of the predetermined section to a predetermined point “Ce” is set after the predetermined section, wherein the predetermined point “Ce” is separated from the end point “Re” by a distance “L wherein the recommended vehicle speed “V wherein the necessary acceleration amount “a” is the acceleration amount required to accelerate the vehicle from the target vehicle speed “V wherein the speed ratio control unit sets the speed ratio of the transmission unit to the accelerating speed ratio “Sa” while the vehicle travels in the front section, and wherein the deceleration control unit obtains a necessary deceleration “Gr” for changing a current vehicle speed “Vc” at a current position of the vehicle traveling in the front section to the target vehicle speed “V
