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 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.
