Abstract: A method for charging an all-solid-state battery that includes a negative electrode containing lithium metal and a solid electrolyte layer includes: measuring an impedance value using an impedance measuring device that measures impedance of the all-solid-state battery in an interface between the negative electrode and the solid electrolyte layer; determining whether the measured impedance value is within an allowable impedance range; and allowing charging the all-solid-state battery when the measured impedance value is within the allowable impedance range. The allowable impedance range is determined by an allowable impedance map and a charging current density to charge the all-solid-state battery, and the allowable impedance map associates the charging current density with an allowable impedance value at which charging is allowed.

Abstract: A vehicle control device according to an embodiment of the present invention comprises a riding cancel switch and a controller. In a case where a first user in the vehicle permitted a riding-together with a second user, after the vehicle stopped at a riding location where the second user will ride on the vehicle, then, when the riding cancel switch is operated before a door of the vehicle is fully opened, the controller prohibits unlocking of the door or opening of the door.

Abstract: A step corresponding control of adjusting driving force of the front wheel motor and driving force of the rear wheel motor when the vehicle passes through a step is executed. In the step corresponding control, after a front wheel ride-up timing at which the front wheel rides up the step and before a rear wheel ride-up timing at which the rear wheel rides up the step, a first control mode in which the front wheel motor is regenerated and the rear wheel motor is powered is executed. In the step corresponding control, after the execution of the first control mode and before the rear wheel ride-up timing, a second control mode in which the front wheel motor is powered and the rear wheel motor is regenerated is executed.

Abstract: A method and device diagnoses a presence or an absence of an abnormality in an evaporated fuel treatment system. The first intake air amount is a detection value of an air flow meter in a state in which the purge control valve has been opened, and is theoretically the same value as the second intake air amount when a purge control valve is closed. The second intake air amount is a theoretical intake air amount indirectly calculated arithmetically, and is a value that reflects a change in the intake air amount accompanying operations of intake system devices. A presence or an absence of an abnormality in the evaporated fuel treatment system is determined based on the first intake air amount and the second intake air amount after a control duty of the purge control valve has reached 100%.

Abstract: An information processing device includes a controller, a ride detection device configured to detect a ride of a user, a storage device configured to store action data of the user, an output device configured to output question data for requesting an answer from the user, and an input device configured to receive an input from the user. The controller outputs, from the output device, output data including at least a question regarding an action of the user taken before riding in a vehicle in accordance with positional information of the vehicle when detecting the ride of the user based on a signal acquired from the ride detection device, acquires an answer to the question from the user as input data via the input device, and associates the input data with the positional information of the vehicle or a POI to store the associated data in a storage device.

Abstract: A control method for a hybrid vehicle is provided. The hybrid vehicle includes: a generator configured to charge a battery by using power of an engine; an electric motor configured to drive a driving wheel by electric power of the battery; and a particulate filter configured to collect particulate matter contained in exhaust gas from the engine. In the control method, the engine is driven to raise a temperature of the particulate filter when a first temperature rise condition is satisfied in which a first predetermined amount or more of the particulate matter is accumulated in the particulate filter and the temperature of the particulate filter is equal to or lower than a predetermined temperature. Drive of the engine is prohibited, when a predetermined first condition that a driver does not intend to drive the engine is satisfied.

Abstract: A vehicle control method causes a controller to execute: processing of determining whether or not a first other vehicle traveling on a second lane, the second lane merging with a first lane on which an own vehicle travels in front of the own vehicle, is traveling diagonally in front of the own vehicle; and processing of, when determining that the first other vehicle is traveling diagonally in front of the own vehicle, controlling vehicle speed of the own vehicle in such a way that a front-rear direction distance from a rear-end position of the first other vehicle to a front-end position of the own vehicle in a front-rear direction of the first lane is shorter than a first target inter-vehicle distance in vehicle speed control to maintain an inter-vehicle distance to a preceding vehicle traveling in front of the own vehicle on the first lane.
