An object detection device is configured to be mounted to an own vehicle to detect an object present around the own vehicle. The object detection device includes a coordinate acquisition section and an object recognition section. The coordinate acquisition section acquires position coordinates of a detection point corresponding to the object on the basis of a plurality of images captured at different positions along with movement of the own vehicle by one imaging section mounted to the own vehicle. The object recognition section recognizes the object without using position coordinates of a movement point that is a detection point corresponding to a moving object but using position coordinates of a stop point that is a detection point different from the movement point.

Object detection device, object detection method, and storage medium

An information processing device for a vehicle includes an object detecting unit, an object information storage unit, and an object information management unit. The object detecting unit detects, based on an output of a sensor mounted on the vehicle, an object located around the vehicle. The object information storage unit stores, as object information, information about the object detected by the object detecting unit. The object information management unit is configured to: receive, from a travelling assistance unit that performs an assistance operation of assisting travelling of the vehicle based on the object information, related information, the related information being related to the assistance operation performed by the travelling assistance unit; determine storage priority of the object information in the object information storage unit based on the related information; and manage a storage state of the object information in the object information storage unit based on the storage priority.

Information processing device and information processing method

An obstacle recognition device of a vehicle provided with a camera capturing an image around the vehicle, includes an acquiring unit sequentially acquiring the image captured by the camera; a feature point extracting unit extracting a plurality of feature points of an object included in the image; a calculation unit calculating each motion distance of the plurality of feature points between the image previously acquired and the image currently acquired by the acquiring unit; a first determination unit determining whether each motion distance of the feature points is larger than or equal to a first threshold; a second determination unit determining whether each motion distance of the feature points is larger than or equal to a second threshold; and an obstacle recognition unit recognizing an obstacle.

Obstacle recognition device

An obstacle identification apparatus acquires an image that is captured by a camera that is mounted to a vehicle. The obstacle identification apparatus calculates a first gradient that is a gradient in a first direction of a luminance value of pixels in the image and a second gradient that is a gradient of the luminance value in a second direction orthogonal to the first direction of the first gradient. Based on the first gradient and the second gradient, the obstacle identification apparatus estimates a shadow boundary that is a boundary between an own-vehicle shadow that is a shadow of the own vehicle and an object outside the vehicle. Based on the estimated shadow boundary, the obstacle identification apparatus estimates the own-vehicle shadow.

Obstacle identification apparatus and obstacle identification program

A parking-lot-leaving support apparatus, to execute parking-lot-leaving support to support a vehicle leaving a parking lot, based on a positional relationship between the vehicle and an obstacle in a back-and-forth direction of the vehicle, includes a determination unit configured to determine whether an obstacle exists in a side direction of the vehicle, based on a detection result of a detection unit that detects an obstacle in the side direction of the vehicle; and an inhibition unit configured to, when the determination unit has determined that the obstacle exists in the side direction of the vehicle, inhibit the parking-lot-leaving support in a direction that coincides with the side direction.

Parking-lot-leaving support apparatus and vehicle

A brake system includes a brake activator which controls, when a slipping condition is detected at a central rear wheel based on a signal detected by a central rear detector, the operating condition of a central rear brake based on the signal detected by the central rear detector so as to reduce a braking force on the central rear wheel lower than a braking force which is obtained as a result of operation of an input member. In this state, when an operation quantity of the input member increases as a result of operation of the input member, changing the operating conditions of both a right front brake and a left front brake, the brake activator increases the braking forces in both a right front wheel and a left front wheel according to an operation quantity of the input member.

Brake system and vehicle

A brake system does not change immediately an operating condition of a left front brake although a slipping condition is detected at the left front wheel based on a signal detected by a left detector in such a state that a slipping condition is not detected at a right front wheel based on a signal detected by a right detector, and does not change immediately an operating condition of a right front brake although a slipping condition is detected at the right front wheel based on a signal detected by the right detector in such a state a slipping condition is not detected at the left front wheel based on a signal detected by the left detector.

A brake system includes a brake activator which reduces, when a slipping condition of a right front wheel is detected based on a signal which is detected by a right detector, both braking forces on the right front wheel and a left front wheel to a lower level than a level of a braking force which is obtained as a result of operation of an input member and which reduces, when a slipping condition of the left front wheel is detected based on a signal which is detected by a left detector, both braking forces on the left front wheel and the right front wheel to a lower level than a level of a braking force which is obtained as a result of operation of the input member.

A brake hydraulic pressure control apparatus is provided with wheel cylinder pressure inference value acquisition means (step) for acquiring an inference value of the wheel cylinder pressure, master cylinder pressure inference value acquisition means (step) for acquiring an inference value of the master cylinder pressure by utilizing a wheel cylinder pressure inference initial value, reaction force compensation amount acquisition means (step) for acquiring a reaction force compensation amount which is a value depending on the variation of the master cylinder pressure caused by the flowing of brake fluid during an ABS control, and differential pressure inference value acquisition means (step) for acquiring an inference value of the differential pressure between the master cylinder pressure and the wheel cylinder pressure by adding the reaction force compensation amount to the difference between the master cylinder pressure inference value and the wheel cylinder pressure inference value.
