Abstract: A parking assistance device performs automatic travel of a vehicle based on teaching travel by a driver. In this regard, the parking assistance device learns a travel route for parking the vehicle in a parking position during the teaching travel, based on the teaching travel. The parking assistance device further performs an automatic travel based on the travel route. A first vehicle speed during the automatic travel is slower than a second vehicle speed during the teaching travel, the first vehicle speed during the automatic travel is slower than a threshold value for a vehicle speed during the automatic travel, and the threshold value for the vehicle speed during the automatic travel is a value of a speed slower than 10 km/h.

Abstract: A parking assist device including a processor is disclosed. The processor superimposes a first parking candidate frame and a second parking candidate frame onto an image around a vehicle when a first obstacle is present at one end of a parking space and a second obstacle is present at another end of the parking space. The first parking candidate frame is parallel with a first obstacle frame indicating a position of the first obstacle. The second parking candidate frame is parallel with a second obstacle frame indicating a position of the second obstacle. The processor displays, on a display device, the first/second parking candidate frames in different display modes. The processor displays, on the display device and in a predetermined color, either one of a first region surrounded by the first parking candidate frame and a second region surrounded by the second parking candidate frame.

Abstract: A driving assistance method is provided that assists driving of a vehicle. The driving assistance method stores a traveling route traveled by the vehicle according to a driving operation of a user in a training traveling mode. All of the traveling route, from a traveling start position to a target parking position in the traveling route, is superimposed on one image displayed on a display. A superimposed image superimposing all of the traveling route from the traveling start position to the target parking position in the traveling route is displayed.

Abstract: A parking assist method according to the present disclosure is for performing autonomous driving of a vehicle on the basis of teacher driving by a driver. The parking assist method includes acquiring, from an imaging device installed in the vehicle, captured images obtained by imaging periphery of the vehicle in time series according to movement of the vehicle during the teacher driving. The method includes recording a travel route of the vehicle in the teacher driving, and generating, on the basis of the captured images, a first enlarged overhead image of a display target range viewed from above. The display target range covers the travel route and periphery of the travel route. The method further includes causing a display device to display the first enlarged overhead image.

Abstract: Provided is a driving assistance apparatus that assists driving of a vehicle. The driving assistance apparatus includes: a training data generator that stores a traveling route traveled by the vehicle according to a driving operation of a user in a training traveling mode, and generates training data for a target route based on the traveling route. The training data generator generates the target route by connecting, for example, between a first point and a second point on the traveling route, in a case where a difference in orientation of the vehicle at the first point and the second point during training traveling is less than a first threshold and distance between the vehicle at the first point and the vehicle at the second point during the training traveling is less than a second threshold.
