Abstract
A driving assistance device can be configured to set a determination point in which an assumed self-position of own vehicle that is assumed on a map, a position of a measurement target feature on the map, and an error predicted as a difference between the position on the map and an actual position of the measurement target feature are associated with each other. The measurement target feature is measurable from the assumed self-position to obtain a measurement position of the measurement target feature based on external information acquired by an external sensor mounted on the own vehicle. The driving assistance device can determine a self-position of the own vehicle on the map based on the external information. The driving assistance device can set a control mode of a driving assistance system of the own vehicle based on the determination point.
