Abstract: An external environment recognition device 101 estimates a blind spot region around a host vehicle based on information detected by a sensor that detects a target around the host vehicle. The external environment recognition device 101 includes a visibility index determination unit 121 that calculates a visibility index of the target based on a coordinate point and a reflection intensity of the target detected by the sensor, and assigns the visibility index to a region from the host vehicle 200 to the coordinate point of the target, a visibility map storage unit 124 that stores the visibility index as a visibility map in association with the region, and a blind spot region estimation unit 127 that estimates the blind spot region based on the visibility map.

Abstract: An electronic control device mounted on a vehicle includes a blind spot region specifying unit, an information obtaining unit, and a blind spot region dangerous event determining unit. The blind spot region specifying unit specifies a blind spot region that is not included in a detection range of a sensor mounted on the vehicle. The information obtaining unit obtains lane information of a road around the vehicle including the blind spot region. The blind spot region dangerous event determining unit judges assumed behavior of a latent obstacle that possibly exist in the blind spot region based on the lane information of the blind spot region and a positional relationship of the blind spot region on the road with respect to the vehicle.

Abstract: In the vehicle control device mounted on the vehicle, the information acquisition unit 11 acquires a vehicle information data group representing vehicle information regarding the behavior of the vehicle 2, a road environment data group 32 representing road environment information regarding the environment of the road on which the vehicle 2 is traveling, and a sensor recognition data group 33 representing sensor recognition information regarding the surrounding environment of the vehicle 2 recognized by the external sensor group 4 mounted on the vehicle 2. Based on the road environment data group 32 and the sensor recognition data group 33, the apparent obstacle prediction unit 12 predicts the future behavior of the apparent obstacle that may hinder the traveling of the vehicle 2. The lane risk map generation unit 15 generates a lane risk map representing the collision risk between the vehicle 2 and the obstacle for each lane of the road based on the vehicle information data group 31 and the future behavior of the apparent obstacle predicted by the apparent obstacle prediction unit 12.

A vehicle control device 1 includes peripheral state detection sensors 301 to 304 that detect a peripheral state for a host vehicle, a blind-spot object estimation processing unit 311 that calculates a blind-spot region around the host vehicle based on the detected peripheral state of the host vehicle and a feature amount of map information, and estimates an object existing in the blind-spot region and a behavior trend of the object, and a potential risk map generation unit 309 that generates a region having a potential risk that the host vehicle approaches the object, based on the behavior trend of the object estimated by the blind-spot object estimation processing unit 311. The vehicle control device 1 further includes an automatic driving planning unit 201 that generates a lane-change trajectory from the peripheral state of the host vehicle and the map information, compares the lane-change trajectory with a potential risk map, and determines whether or not lane change of the host vehicle is possible, and a vehicle motion control unit 203 that controls an operation of the host vehicle in accordance with the determination of whether or not the lane change is possible.
