A parking assistance device according to the present disclosure performs automatic travel of a vehicle based on teaching travel by a driver. The parking assistance device includes a memory and a hardware processor coupled to the memory. The hardware processor is configured to: learn a travel route for parking the vehicle in a parking position and a speed, a steering angle, and braking operation of the vehicle during the teaching travel, based on the teaching travel; and modify the speed, the steering angle, or the braking operation in the automatic travel of the vehicle from the speed, the steering angle, or the braking operation in the teaching travel, based on any of a regulation for the automatic travel of the vehicle, environmental information relating to an environment around the vehicle, or geographic information relating to a road condition around the vehicle.

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.

A vehicle state determination device includes an input unit and a controller. The input unit receives sidewalk information indicating a state of a sidewalk region which a moving body passes through and roadway information indicating a state of a roadway region adjacent to the sidewalk region. The controller determines whether or not a sidewalk entering operation is possible based on the sidewalk information and the roadway information. The sidewalk entering operation is an operation in which a vehicle trying to enter the roadway region by crossing the sidewalk region enters the sidewalk region.

Vehicle state determination device and vehicle state determination method

A determination device includes an input unit and a controller. The input unit receives information on a sidewalk area and information on a target object recognized in the sidewalk area. The sidewalk area exists between a position where a vehicle is present and a non-sidewalk area. The controller (i) divides the sidewalk area into a plurality of partial areas including at least a first partial area and a second partial area based on the information on the sidewalk area, the first partial area being closest to the vehicle among the plurality of partial areas, and the second partial area being adjacent to the non-sidewalk area, and (ii) determines, based on the information on the target object, at least one partial area among the plurality of partial areas to be a range where the vehicle is allowed to enter.
