Abstract: An information processing device configured to communicate with an external service provider includes a reception unit configured to receive a request regarding communication quality necessary for executing an external service from the external service provider, an acquisition unit configured to acquire, from a predetermined database, information on the communication quality necessary for executing the external service based on the request received by the reception unit, and a transmission unit configured to transmit the information acquired by the acquisition unit to the external service provider.

Abstract: A system includes a vehicle and a control device. The vehicle includes a reception unit for receiving an instruction related to remote control from the control device, a vehicle control unit for executing any one of first vehicle control and second vehicle control, the first vehicle control being control based on the instruction related to the remote control, and the second vehicle control being control determined by the vehicle itself in accordance with a traveling environment, and a transmission unit for notifying a predetermined control result to the control device when the second vehicle control is executed by the vehicle control unit. The control device includes a remote control unit, a transmission unit, and a reception unit. When the control result is notified from the vehicle, the remote control unit of the control device executes the remote control based on a content of the control result.

Abstract: A communication control device for performing communication with a plurality of vehicles, comprising: a communication unit that performs communication including acquisition of vehicle data with a plurality of vehicles; a database that stores data for forming a digital twin that is time-synchronized with a real space on a virtual space based on vehicle data acquired by the communication unit; and a control unit that controls a frequency of communication performed by the communication unit, wherein when there is a first vehicle in which a distance from a surrounding object is less than a first threshold value on the digital twin, the control unit increases a frequency of communication performed between the first vehicle and the surrounding object than when the distance between the first vehicle and the surrounding object is equal to or greater than the first threshold value.

Abstract: A system includes: a server; and a moving body wherein, the server is configured to communicate with the moving body, predict occurrence of a loss of communication with the moving body, and send information necessary to execute a first process to the moving body when the loss of communication with the moving body is predicted to occur; and the moving body is configured to receive the information from the server, and execute the first process based on the received information.

Abstract: A communication abnormality determination device mounted on a vehicle that communicates with a server includes a detection unit that detects that a communication disruption occurs between the vehicle and the server, and a determination unit that determines a cause of occurrence of the communication disruption based on a communication strength at a first position at which the communication disruption occurs.

Abstract: A vehicle communication control device that communicates with a plurality of vehicles, the vehicle communication control device including: a database generated from data acquired from the vehicles; and a control unit that controls data acquired from the vehicles based on information regarding a state of an own vehicle acquired from the vehicles and a completeness of the database.

Abstract: A control device that controls a battery includes one or more processors configured to: acquire a physical quantity of the battery; detect a predetermined signal; control a relay based on the physical quantity of the battery, the relay being connected between the battery and a predetermined device to which power is supplied from the battery; connect the relay when the physical quantity of the battery has continuously satisfied a predetermined condition for a first time period while the relay is in a disconnected state; and change the first time period depending on whether the predetermined signal has been detected by the one or more processors.

Abstract: An engine includes a cylinder block in which a cylinder is formed, a piston arranged to be reciprocally movable in the cylinder, a cylinder head that is arranged on an upper side of the cylinder block and forms a combustion chamber between an inner peripheral surface of the cylinder and an upper surface of the piston, and an ignition plug arranged in the cylinder head. An inner peripheral portion of the cylinder head includes an inner peripheral side portion formed to be flush with the inner peripheral surface of the cylinder, and a tilting portion tilting from the upper surface of the piston to a side surface is formed on the piston.

Abstract: A charging control device includes a processor. The processor is configured to control charging of a plurality of battery cells that configure an assembled battery, during charging, in a case in which a voltage value of a battery cell having a highest voltage among the plurality of battery cells is equal to or greater than a threshold value and a current value is equal to or less than a set value, measure a closed circuit voltage (CCV) of the plurality of battery cells, and for a battery cell for which a potential difference with respect to a voltage of a battery cell with a lowest measured CCV is equal to or greater than a predetermined value, execute discharging processing so as to eliminate the potential difference.
