Abstract: A vehicle control device in an embodiment includes a recognition unit that recognizes a surrounding situation of a vehicle and a driving control unit that controls one or both of steering and acceleration or deceleration of the vehicle on the basis of the surrounding situation recognized by the recognition unit, and in a case where the vehicle merges into a second lane from a first lane in which the vehicle travels, and a section of the second lane before merging recognized by the recognition unit is downhill, the driving control unit makes a speed or acceleration of the vehicle higher than in a case where the section before merging is not downhill.

Abstract: In a stress measurement method, an object to be measured is vibrated at a plurality of oscillation frequencies, and a temperature amplitude of the object to be measured is measured by using a temperature sensor. Parameters of a one-dimensional heat conduction equation described below are identified by performing curve-fitting, on the basis of the one-dimensional heat conduction equation, on a measurement value of the temperature amplitude with respect to frequency characteristics of a temperature change component and a phase component based on a thermoelastic effect. The frequency characteristics are obtained at the plurality of oscillation frequencies. The one-dimensional heat conduction equation indicates a theoretical solution of a temperature amplitude on a surface of a coating film based on heat conduction and the thermoelastic effect of each of a substrate and the coating film. Then, a stress of the object to be measured is obtained based on the identified parameters.

Abstract: A vehicle control device includes a recognizer configured to recognize a surrounding situation of a vehicle and a driving controller configured to control acceleration, deceleration, and steering of the vehicle independently of an operation of an occupant of the vehicle on the basis of a recognition result of the recognizer. When it is recognized that the vehicle passes through a complex intersection where two or more intersections are combined by turning left or right at the complex intersection, the recognizer excludes at least a traffic signal closest to the vehicle among traffic signals present at positions capable of being visually recognized from the vehicle in a traveling direction of the vehicle from traffic signals whose states are required to be taken into account by the vehicle in a state in which the vehicle has entered the complex intersection.
