Abstract
A driving assistance apparatus in a subject vehicle includes a driving assistance section. A subject-vehicle estimated trajectory is estimated as a subsequent traveling trajectory from a current position and a traveling orientation of the subject vehicle. A neighboring-vehicle estimated trajectory is estimated as a subsequent traveling trajectory of a neighboring vehicle by acquiring trajectory estimation information. A determination area is designated to include a crossing point included in the subject-vehicle estimated trajectory and the neighboring-vehicle estimated trajectory. It is determined whether the determination area includes an intersection node in road map information. A first driving assistance level is used when the determination area does not include the intersection node; the first driving assistance level is smaller in driving assistance than a second driving assistance level used when the determination area includes the intersection node.
