Abstract: Provided are an own-vehicle position estimation device and an own-vehicle position estimation method which are capable of estimating the position of an own vehicle with high accuracy, including not only one-dimensional distances of movement but also two-dimensional directions of cornering. There are provided a vehicle position estimation unit 2 for calculating the position of a vehicle based on an output from a sensor for detecting a behavior of the vehicle, a wireless position estimation unit 1 for communicating with a wireless device 101 installed at an arbitrary position and for calculating the relative positions of the vehicle and the wireless device 101, and a position estimation parameter correction unit 3 for correcting parameters used for calculating at least the position of the vehicle and information about the cornering angle of the vehicle by the vehicle position estimation unit 2. The position estimation parameter correction unit 3 compares an amount of movement of the vehicle calculated by the wireless position estimation unit 1 with an amount of movement of the vehicle calculated by the vehicle position estimation unit 2, and corrects the parameters.

Abstract: An image processing device includes: an input unit that acquires each photographed image from a plurality of cameras installed in a vehicle; a photographing state detection unit that detects whether a malfunction has occurred in a photographing state of each of the photographed images; a likelihood calculation unit that calculates, for each of the cameras, a likelihood indicating a degree of malfunction of the photographing state on the basis of each of the photographed images; and a likelihood update unit that updates the likelihood to a new likelihood on a basis of a determination obtained by integrating the likelihoods for each of the cameras calculated by the likelihood calculation unit, in which the likelihood updated by the likelihood update unit is outputted as the likelihood for each of the cameras.

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 provide a vehicle control device capable of avoiding the collision with an obstacle by performing an appropriate collision assessment and appropriate driving assistance having considered a detection error of the obstacle. The vehicle control device 100 includes a collision assessment unit 3 which assesses whether or not there is a possibility of an ego vehicle and an obstacle colliding with each other, and a driving assistance control unit 4 which performs driving assistance for avoiding the collision. The collision assessment unit 3 includes a region setting unit 31 which sets an ego vehicle region and an obstacle region, a location prediction unit 33 which predicts future locations of the ego vehicle region and the obstacle region, and an overlap assessment unit 34 which assesses that there is a possibility of collision when the ego vehicle region and the obstacle region overlap at the future location. The region setting unit 31 changes, on the basis of a moving speed of the obstacle, the size of the ego vehicle region and/or the obstacle region from the size of the ego vehicle and/or the obstacle, to thereby set the ego vehicle region and the obstacle region.

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: The present invention sets an appropriate parking route according to a surrounding situation. A vehicle control device which controls traveling of a vehicle includes: a surrounding environment recognition unit which recognizes a surrounding environment of an own vehicle, detects a parking space, sets a target parking position and a travelable space; and a vehicle control unit which guides and controls the own vehicle to the target parking position in the travelable space. The vehicle control unit guides and controls the own vehicle to the target parking position without traveling the own vehicle in a space behind the target parking position.
