Abstract: A vehicle control device, which reduces intervention in automatic parking by a driver, includes a processor and a memory, that control the vehicle to a target parking position. The vehicle control device includes an obstacle detection unit detecting a position of an obstacle around the vehicle, a travelable region setting unit that determines a region where the vehicle may travel based on the position of the obstacle, and sets the target parking position within the travelable region, a route generation unit that calculates a travel route to the target parking position within the travelable region, and an automatic parking execution unit that causes the vehicle to automatically travel toward the target parking position. When a driver intervenes during the automatic traveling, the route generation unit stores vehicle state information at the time of the intervention, and resets the travelable region based on the driver operation intervention information.

Abstract: Provided is a collision avoidance assistance device with improved functionality and usability, which can suppress an excessive application or emergency application of the brakes in assisting avoidance of a collision with an object traveling in a lane orthogonal to a host vehicle (a road crossing the host vehicle). The collision avoidance assistance device calculates an amount of time to reach a predicted collision point that is an estimated amount of time until the host vehicle reaches the predicted collision point when the host vehicle is decelerated by a predetermined deceleration or braking force, and changes (increases or decreases) a brake application determination threshold based on a predicted passing time and the amount of time to reach the predicted collision point, the predicted passing time being an estimated time required for the object to pass through an intersecting region (predicted intersecting region) between a predicted path of the object (predicted target path) and a predicted path of the host vehicle (predicted host vehicle path).

Abstract: A control device according to the present disclosure is to provide greater safety than in the conventional system for the occupant while alighting from the vehicle. A control device 10 is mounted on a vehicle 1. The control device 10 includes an attention degree estimation unit 11 and an alighting restriction unit 12. Based on at least one of results detected by an occupant sensor 3 for detecting motion of an occupant of the vehicle 1 and detected by a vehicle sensor 4 for detecting a state of the vehicle 1, the attention degree estimation unit 11 estimates a degree of attention of the occupant to an approaching object approaching the vehicle 1. When the degree of attention of the occupant estimated by the attention degree estimation unit 11 is below the predetermined threshold, the alighting restriction unit 12 causes at least one of the door opening/closing device 6, the audio output device 7, and the image display device 8 in the vehicle 1 to execute the alighting restriction operation.

Abstract: Provided is a vehicle control device capable of improving robustness against an attitude change of an occupant during preceding vehicle follow-up control in a straddle type vehicle such as a motorcycle. A vehicle control device 100 for a straddle type vehicle that controls a driving force during preceding vehicle follow-up control for causing an own vehicle to follow a preceding vehicle, in which the driving force (which is a control amount of the preceding vehicle follow-up control) is corrected according to an attitude (attitude change) of a driver detected by an attitude detection device 800 during the preceding vehicle follow-up control. Further, the driving force is corrected on the basis of the attitude, the driving torque of the own vehicle, and the acceleration of the own vehicle. In addition, the driving force (according to the attitude) is corrected from at least one of the own vehicle speed of the own vehicle, the target speed, the inter-vehicle distance between the own vehicle and the preceding vehicle, the target inter-vehicle distance, and the relative speed.

Abstract: At the time of travel following a travel route, even if an environment around the travel route changes, estimation of a host vehicle position from a stationary object is realized. A vehicle control device has a processor and a memory and controls traveling of a vehicle, and includes a sensor that acquires surrounding environment information of the vehicle, a surrounding environment storage unit that acquires a stationary object from surrounding environment information acquired by the sensor, calculates a position of the stationary object, and stores the position of the vehicle on a travel route and a position of the stationary object in association with each other. The surrounding environment storage unit stores three or more of the stationary objects at each position on a travel route as stationary objects for host vehicle position estimation in a case of receiving a command to start storing the surrounding environment information and the travel route.

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 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.
