Abstract: A vehicle control device includes a counting unit that counts rotation of wheels by a sensor; and a rotation determination unit that determines the rotation based on a count value of each of the wheels obtained by the counting unit. Based on a movement distance of a vehicle, the movement distance of each of the wheels from rotation detection to the next rotation detection is defined as a rotation detection travel distance of each of the wheels. The rotation determination unit determines a rotation direction of a wheel a second time is a direction opposite to that detected for a first time when rotation detection is not performed even once for a first reference wheel having a rotation detection travel distance equal to or less than a rotation detection travel distance of the first determination target wheel while the rotation of the selected first determination target wheel is detected twice.

Abstract: The vehicle 1 includes a tow vehicle 2 and a loading platform 3. The loading platform 3 includes a ROM 23 storing loading platform information including a loading platform type and a plurality of first external sensors 8 that detect an object around the loading platform 3. The tow vehicle 2 acquires the loading platform type from the loading platform 3 and includes an ADAS ECU 10 that performs a driving assist of the vehicle 1 based on the acquired loading platform type and a plurality of second external sensors 9 that detect an object around the tow vehicle 2. The ADAS ECU 10 converts the acquired detection data of each of the first external sensors 8 from a sensor coordinate system of each first external sensor to a loading platform coordinate system, further converts from the loading platform coordinate system to the tow vehicle coordinate system, integrates detection data of the first external sensor 8 and detection data of the second external sensor 9 into the tow vehicle coordinate system, and calculates the relative position and the relative speed of the detected object based on the integrated detection data.

Abstract: An object of the present invention is to provide a vehicle control device capable of improving ride comfort of a driver. A lane change detection unit 205 of a vehicle control device 200 determines a possibility of cut-in of an adjacent vehicle immediately in front of an own vehicle on the basis of an adjacent vehicle relationship value (for example, a relative speed between the own vehicle and the adjacent vehicle) in an advancing direction. An acceleration/deceleration control unit 206 corrects acceleration/deceleration of the own vehicle on the basis of the possibility of the cut-in determined on the basis of the adjacent vehicle relationship value in the advancing direction.

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: An object of the present invention is to improve convenience of parking assistance. A control device 111 of a driving assistance device 200 controls an emergency brake device that actuates an emergency brake based on a distance to an obstacle detected by a sonar 3 constituting the detection device mounted on a vehicle 1 and a parking assistance device that provides parking assistance for the vehicle 1. In the sonar 3 constituting the detection device, an upper limit value and a lower limit value that define a range of the distance in which an obstacle can be detected are determined in advance. The control device 111 invalidates the operation of the emergency brake device when the distance between the vehicle 1 and the obstacle at a target vehicle stop position which is a target position for stopping the vehicle 1 in the parking assistance is smaller than the lower limit value.

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.
