PARKING ASSISTANCE DEVICE AND PARKING ASSISTANCE METHOD

A parking assistance device according to the present disclosure performs automatic traveling of a vehicle based on teacher traveling by a user, and includes a memory and a processor coupled to the memory. The processor is configured to: cause the memory to store information about a travel path in the teacher traveling; correct the travel path in order that a position of a target position of the automatic traveling in a vehicle width direction is closer to a structure defining a parking area configured to park the vehicle and a path to the target position having a curvature smaller than a threshold is kept longer, according to a relative positional relationship between the structure and a start position of the automatic traveling on the travel path; and control the vehicle based on the corrected travel path.
