Abstract: A driving assistance device controls the speed of an own vehicle based on a predicted traveling state of a preceding vehicle, and includes a traveling scene recognition unit that detects the distance until the preceding vehicle reaches an intersection, a determination unit that determines a traveling scene of the preceding vehicle at the intersection, and a calculation unit that selects the preceding vehicle prediction model according to the traveling scene determined by the determination unit from among a plurality of preceding vehicle prediction models recorded for each traveling scene in which the preceding vehicle travels, and inputs a distance until the preceding vehicle detected by the traveling scene recognition unit in the selected preceding vehicle prediction model reaches the intersection so as to calculate a predicted traveling state of the preceding vehicle after a predetermined time.
