Abstract: A vehicle front recognition apparatus includes an imager that captures an image of an environment ahead of a vehicle on the road, an image analyzer that analyzes the image of the environment with artificial intelligence to segment the image areas of the image by classes to which objects captured in the image belong, and a road information acquirer that acquires high-precision map information ahead of the vehicle. The vehicle front recognition apparatus acquires dynamic information that is not included in the high-precision map information from the classes. The image analyzer includes a feeling-of-strangeness area extractor extracting a feeling-of-strangeness area using the classes from the image areas. The vehicle front recognition apparatus further includes a feeling-of-strangeness area verifier that verifies whether the vehicle can pass through the feeling-of-strangeness area and a notifier that notifies a driver when the vehicle cannot pass through the feeling-of-strangeness area.

Abstract: A vehicle drive assist apparatus is to be applied to a vehicle. The apparatus includes an object recognizer, a risk area setter, a risk level setter, a route candidate setter, a route evaluation value calculator, and a vehicle travel route setter. The object recognizer recognizes an object in front of the vehicle. The risk area setter sets, when small objects are around the object, a risk area including the small objects. The risk level setter sets a risk level for the risk area based on a distribution state of the small objects within the risk area. The route candidate setter sets patterns of route candidates for avoiding a risk resulting from the risk area. The route evaluation value calculator calculates a route evaluation value for each of the route candidates. The vehicle travel route setter sets, as a vehicle travel route, the route candidate having an optimum route evaluation value.

Abstract: An accompanying mobile body that can swiftly reflect a change in accompanying conditions by an instruction from a user on a state of movement. A predicted location calculation section calculates a predicted location of a user after a predetermined time period based on a state of movement of the user recognized by a movement state recognition section. An accompanying control section performs accompanying control to cause a shopping cart to move by a traveling unit toward a target location of accompanying that is a location apart from the predicted location by a specified distance in a specified direction. An accompanying condition change section changes one or both of the specified direction and the specified distance in accordance with an instruction to change from the user.

Abstract: An accompanying mobile body in which a response to an abrupt change in a traveling direction of a user is restrained from being delayed. A movement state recognition section recognizes a moving direction and a moving speed of a user. A predicted location calculation section calculates a predicted location of the user after a first predetermined time period based on the moving direction and the moving speed of the user. An accompanying control section performs accompanying control to cause an accompanying mobile body to move by a traveling unit toward a target location of accompanying that is a location apart from the predicted location by a specified distance in a specified direction.

Abstract: An accompanying control section performs accompanying control to cause a traveling unit to operate based on a state of movement of a user recognized by a movement state recognition section in such a manner that a shopping cart accompanies the user while maintaining a state of keeping a specified distance from the user in a specified direction. A job information reception section receives an input of job information made by the user. A candidate material recognition section extracts at least one candidate material to be used in work based on the job information. A route retrieval section retrieves a route from a current location of the shopping cart to a display place of each selected material selected among the at least one candidate material.
