  • Publication number: 20220222946
    Abstract: Provided are a traffic environment recognition device and the like capable of quickly recognizing a traffic environment in a traveling direction of a host vehicle. On the basis of surrounding situation data D_info, a vehicle control device 1 recognizes a moving object and a landmark within a predetermined range in a traveling direction of a host vehicle 3, and also recognizes a positional relationship between the moving object and the landmark. When a bicycle 21 is recognized as the moving object, a first moving object noun “bicycle” is selected, and when a guard fence 23 is recognized as the landmark, a first landmark noun “fence” is selected. Further, a positional relationship word “behind” indicating a positional relationship between the bicycle 21 and the guard fence is selected. Then, first scene data is created by associating “bicycle”, “behind”, and “fence” with each other.

  • Patent number: 11325593
    Abstract: An automated driving apparatus acquires a position relation between a vehicle in front and a host vehicle based on peripheral state data D_info. When an intervehicular distance D1 between the host vehicle and the vehicle in front in a front-and-back direction has a value smaller than a first predetermined value D1ref, it is estimated that a risk of appearance Risk_ap is low compared with a case in which the distance in the front-and-back direction has a value equal to or larger than the first predetermined value D1ref.

  • Publication number: 20210286372
    Abstract: Provided is a control apparatus for controlling broadcast data to be broadcasted to an occupant of a movable object with an automated drive function, comprising: a travelling road identification unit for identifying a predetermined travelling road of the movable object corresponding to a destination set in the movable object; a setting unit for setting, according to the predetermined travelling road, a recommended switching point for switching predetermined automated drive to driver subjected manual drive in the predetermined travelling road, and setting predetermined passage time when the movable object passes through the recommended switching point; and a broadcast plan generation unit for generating a broadcast plan for broadcasting predetermined broadcast data to an occupant of the movable object according to the recommended switching point; wherein the broadcast plan generation unit determines an order of the broadcast data to be broadcasted within a predetermined period before or after the recommended s

  • Publication number: 20210284064
    Abstract: A control apparatus for controlling notification data presented to an occupant of a movable object having an automated driving function. The control apparatus includes a travel road specification unit configured to specify a road scheduled to be travelled by the movable object corresponding to a destination set for the movable object. The control apparatus includes a setting unit configured to set, according to the road scheduled to be travelled, a switching recommendation point for switching from automated drive to driver-led manual drive on the road scheduled to be travelled, and estimate a scheduled passing time instant at which the movable object passes the switching recommendation point. The control apparatus includes a notification plan generation unit configured to generate a notification plan for presenting predetermined notification data to the occupant of the movable object according to the switching recommendation point and the scheduled passing time instant.

  • Publication number: 20210139027
    Abstract: Provided is a risk estimation device capable of appropriately estimating a risk in a traveling direction of an own vehicle even under the condition that a relationship between a traffic participant and a road condition is inappropriate. The risk estimation device recognizes a traffic participant, a road condition, and a condition of the traffic participant in the traveling direction of the own vehicle based on a surrounding condition data, determines, by using a reference relationship model, whether the relationship between the traffic participant and the road condition is appropriate, estimates, by using a risk model, a traveling risk in a case where the relationship between the traffic participant and the road condition is determined to be appropriate, and estimates the traveling risk according to the condition of the traffic participant in a case where the relationship between the traffic participant and the road condition is determined to be inappropriate.
