The present invention provides a vehicle control device capable of ensuring safety and ride comfort. The device includes: a self-location estimation processing unitestimating self location (absolute position information on a map) of a vehicle by matching sensor information obtained from external sensorstomounted in the vehicle with map information including future information as a point group; a solid object movement predicting unitpredicting movement of an object as a factor of obstructing the matching with the map information; and a driving movement candidate generating unit (driving movement planning unit)making a driving movement plan of the vehicle on the basis of a result of predicting movement of the obstructive factor object, a result of presuming a road situation at future time, and an estimation result of a position error of the vehicle at future time.

Vehicle control device

To provide a vehicle control system that is capable of planning a trajectory that can ensure more visibility and enables safe traveling when an invisible range of a sensor exists. A vehicle control system that plans a target trajectory of a vehicle based on recognition information from an external environment sensor, the vehicle control system including a recognizing unit that recognizes an object at a periphery of the vehicle based on the recognition information; and a trajectory planning unit that plans the target trajectory such that an actual detection range of the external environment sensor becomes wide when the recognizing unit recognizes the object.

Vehicle control system, and vehicle control method

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.

Vehicle control device, and vehicle control system

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.

Vehicle control system

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.

Vehicle control device for autonomous vehicle operation

There are provided a vehicle control device and a vehicle control system capable of improving efficiency and reliability of auto valet parking compared to the related art when a communication failure occurs. A vehicle control device mounted on a vehicle includes a recognition unit, an estimation unit, a communication unit, a determination unit, a trajectory generation unit, a vehicle control unit, and a retreated position decision unit. When the determination unit determines that communication of the communication unit is abnormal, the trajectory generation unit generates a target trajectory along which the vehicle drives to a retreated position decided by the retreated position decision unit.

Vehicle control device and vehicle control system

When an automatic parking function and an automatic driving function are provided in the same system, a vehicle stops for parking trajectory calculation when switching between an automatic driving mode and an automatic parking mode is performed, and thus, there is concern that a driver is likely to feel discomfort with this stop. A surrounding environment recognition unit, a host vehicle position detection unit, an automatic driving trajectory calculation unit that calculates an automatic driving trajectory based on a current position and a surrounding environment of the host vehicle and a destination input result, a parking section detection calculation unit that detects a parking space around a destination based on the surrounding environment of the host vehicle, an automatic parking trajectory calculation unit that calculates an automatic parking trajectory along which the host vehicle is parked in the parking space, and a transition mode trajectory calculation unit that calculates a transition mode trajectory based on the automatic parking trajectory and the surrounding environment are provided. The automatic parking trajectory calculation unit calculates the automatic parking trajectory while the host vehicle is tracking the transition mode trajectory.

Vehicle traveling control device

The purpose of the present invention is to provide a coast-stop control device that makes it possible to change gears to an appropriate gear change while traveling, before the engine is stopped. The present invention is a coast-stop control device for performing coast-stop control that automatically stops an engine while the vehicle is traveling, the coast-stop control device being characterized: in being provided with an engine stop condition-assessing means for assessing whether it is possible to stop the engine and a gear change control means for controlling the gear change ratio of a gear change mechanism; and in controlling the gear change mechanism to a prescribed gear change ratio when the engine stop condition-assessing means determines that an engine stop condition has been met.

Coast-stop control device

A parallel-connected electricity storage system in which a plurality of chargeable and dischargeable electricity storage elements are connected in series as an electricity storage element row and a plurality of the electricity storage element rows are connected in parallel includes an electricity-storage-element-voltage measuring device that measures an electricity storage element voltage of each of the electricity storage elements, an electricity-storage-element-state estimating device that estimates an electricity storage element state of each of the electricity storage elements, an electricity-storage-element-current measuring device that measures an electricity storage element current of each of the electricity storage element rows, a parallel-connected switch that performs connection and disconnection to and from the parallel-connected electricity storage system for each of the electricity storage element rows, and a parallel-connected-switch control means for turning on the parallel-connected switch on the basis of the electricity storage element voltage, the electricity storage element state, and the electricity storage element current.
