Abstract
There is provided a driving assistance device. When there is a possibility that weather influences a detection performance of a vehicle detection unit configured to detect a preceding vehicle traveling in front of a subject vehicle and to measure an inter-vehicular distance to the preceding vehicle, a speed reduction control assistance unit enables a speed reduction control unit to perform a primary speed reduction control at a predetermined distance ahead of an entry or an exit of a tunnel-shaped road structure. Thereafter, when the vehicle detection unit detects the preceding vehicle and the inter-vehicular distance is equal to or smaller than a predetermined value, the speed reduction control assistance unit enables the speed reduction control unit to perform a secondary speed reduction control.
