Abstract: A parking assist device capable of parking assistance that ensures high accuracy of a parking location is provided. A parking assist device that assists in performing an operation of parking a vehicle includes a parking-allowing location calculation unit that before the vehicle stops at a parking-allowing location, calculates and updates the parking-allowing location a plurality of times, and a parking route calculation unit that calculates a parking route. The parking route calculation unit sets a minimum turning radius for calculating the parking route, based on the amount of a shift between the parking-allowing location not updated and the parking-allowing location having been updated, and calculates the parking route, using the minimum turning radius. The minimum turning radius is set larger than the minimum value of a turning radius unique to the vehicle.

Abstract: A vehicle control device includes a processor, a memory and a sensor that acquires surrounding environment information of the vehicle, a host vehicle position estimation unit that estimates the route of the vehicle, a surrounding environment storage unit that stores the surrounding environment information and the route estimated by the host vehicle position estimation unit in association with each other, a vehicle-speed threshold determination unit that sets a vehicle-speed threshold value when the surrounding environment storage unit stores the surrounding environment information and the route in association with each other, and determines whether or not a current vehicle speed exceeds the vehicle-speed threshold value when the surrounding environment storage unit stores the surrounding environment information and the route, and a warning unit that performs a notification of an excess of the vehicle speed when the vehicle-speed threshold determination unit determines that the vehicle speed exceeds the vehicle-speed threshold value.

Abstract: A vehicle parking control device has a processor and a memory to control the vehicle from a starting to a target parking position. The vehicle control device includes an obstacle detection unit detecting obstacles around the vehicle, a travelable area setting unit setting an area where the vehicle can travel based on a position of the obstacles, and sets the target parking position in the travelable area, a route generation unit calculating a travel route to the target parking position in the travelable area, and a parking execution unit that causes the vehicle to travel toward the target parking position on the basis of the travel route. The route generation unit generates a route from a parking start position to the target parking position, and corrects a distance of the section to a predetermined distance when the distance of the section is less than the predetermined distance.

Abstract: When a vehicle is caused to autonomously travel and is guided to a target point, if an error from a design value occurs in a position or dimensions of an external-environment sensor due to a secular change of the vehicle, a riding state, or a loading state, an error also occurs in a sensing result. Thus, positional accuracy at the target point is deteriorated. There is provided a vehicle control method of controlling a vehicle by a vehicle control device including a processor and a memory. The vehicle control method includes a step of storing route information up to a predetermined point by the vehicle control device, and a step of performing autonomous traveling based on the route information by the vehicle control device. In the step of storing, a section for collecting information for disturbance correction on an external-environment sensor is stored. In the step of performing the autonomous traveling, the disturbance correction on the external-environment sensor is performed using information collected during traveling in the section.
