Abstract: A vehicle control device that autonomously controls a vehicle so as not to cause rapid deceleration that leads to a deterioration in ride quality. The vehicle control device controls first and second deceleration, means that reduce a speed at a deceleration rate large than a deceleration rate of the first deceleration means. The vehicle control device includes a blind spot area detecting unit that detects a blind spot area of a sensor that recognizes an external environment, and a blind spot object estimating unit that estimates a blind spot object that is a virtual moving body hidden in the blind spot area. When a vehicle approaches the blind spot area at a speed reduced by the first deceleration means, the vehicle is decelerated by the second deceleration means when a type of a moving body detected by the sensor is different from a type of the blind spot object.

Abstract: A moving object behavior prediction device improves prediction accuracy and includes: an input map generation unit that generates a single input map in which a region capable of containing a plurality of the moving objects is divided into a plurality of cells, in which each of the cells stores related information of a static object and related information of the moving object; a movement amount estimation unit that estimates a movement amount as a feature amount of each cell from the input map, using a trained convolutional neural network; a movement amount acquisition unit that acquires a movement amount at a current position of the moving object from a movement amount stored in a peripheral cell the moving object; and a future position prediction unit that predicts a future position of the moving object based on a feature amount at a current position of the moving object.

Abstract: A driving assistance device includes a recording unit that records vehicle past traveling positions and related position estimation information, and a relative position estimation unit that estimates a vehicle relative position based on a sensor, adds a history of the relative position to the past traveling position, and uses the output of the sensor. The driving assistance device further includes a position estimation unit that estimates a vehicle position with respect to the past traveling positions and adds a history of the estimated position to the past traveling position, in addition to a deviation determination unit that determines deviation from the past traveling positions using a distribution of the past traveling positions, the vehicle position relative to the past traveling positions, and a reference value. The driving assistance device includes a control unit that controls the vehicle to cancel a warning or deviation when the deviation is determined.

Abstract: A vehicle control system capable of ensuring safety at a low cost even when a control device fails, includes a first control device that implements at least two automatic driving-related functions based on information from external sensors and/or information from a map database, a second control device that implements fewer automatic driving-related functions than the first control device based on the information from the sensors and/or the map database, and a vehicle motion control device that automatically controls a driving state of a host vehicle based on a function planned by the first or second control device including: a backup determination unit that determines whether the future function planned by the first or second control device is backed up by the second control device; and an interface that notifies a driver that system responsibility is switched to the driver, when the backup is not available.

Abstract: Provided is a vehicle control device that can ensure riding comfort or safety. A vehicle control device includes a driving plan calculation unit that calculates a drivable area, which is a space in which an own vehicle is safely drivable, based on a driving environment around the own vehicle and a destination of the own vehicle; and a vehicle motion control unit that calculates a target track including a route and a velocity satisfying a predetermined riding comfort condition in the drivable area calculated by the driving plan calculation unit and controls the own vehicle so as to follow the target track.
