DRIVING ASSISTANCE DEVICE AND DRIVING ASSISTANCE METHOD

A driving assistance device includes a processor connected to a memory. In a teaching traveling mode, the processor stores, in the memory, a teaching traveling path obtained by a vehicle traveling from a current position to a start position designated by a user, and generates teaching data related to a teaching path obtained by reversing the teaching traveling path from an end point toward a start point. The processor causes the vehicle to travel along the teaching path in an automated traveling mode. The processor generates, in the teaching traveling mode, a recommended path in which a turning radius of a stroke of forward travel is larger than a turning radius of a stroke of backward travel in a range from the current position to the start position. The processor outputs, in the teaching traveling mode, display information for displaying a display screen including the recommended path.
