An execution unit calculates a first remaining rate that is a rate of a remaining number of times data is allowed to be written to a storage area during execution of the first operating system relative to a first upper limit count. The execution unit calculates a total remaining rate that is a rate of a remaining number of times data is allowed to be written to the storage area during execution of the first operating system and the second operating system relative to a total upper limit count. The execution unit changes a value of the first remaining rate to a value of the total remaining rate when the first remaining rate is greater than the total remaining rate.

Information management device, non-transitory computer-readable storage medium storing information management program, and method for managing information

A solar control system includes a solar unit configured to output electric power generated by a solar panel, a battery configured to be supplied with electric power from the solar unit, a first DDC and a second DDC inserted in parallel between the solar unit and the battery and each configured to control electric power, supplied from the solar unit to the battery, based on a command value, a first sensor configured to detect an output current from the first DDC, and a second sensor configured to detect an output current from the second DDC.

Solar control system, method, medium, and vehicle

The image extraction device includes a processor. The processor acquires footage of outside a vehicle captured by an image capture device onboard the vehicle, extracts from the footage plural extracted images that are images including an image captured at a point in time satisfying a predetermined condition, infers a desired image that is an image most desirable to an occupant of the vehicle from out of the plural extracted images, and outputs the desired image.

Image extraction device, vehicle, image extraction system, image extraction method, and storage medium storing image extraction program

A vehicle information management device, a vehicle information management method, and a storage medium are provided. Execution circuitry writes data to a memory in conjunction with execution of each of multiple applications. The execution circuitry determines whether the remaining number of writable times to the memory has become a prescribed value or less. When the determination is affirmative, the execution circuitry reduces a write frequency of data to the memory in conjunction with execution of each application of the entirety of the applications, as compared with the write frequency of data in a case in which the determination is negative.

Vehicle information management device, vehicle information management method, and storage medium

A control device is provided with a control section that operates an apparatus on board a vehicle and controls a first frequency, which relates to an operation sound of the apparatus, such that the first frequency corresponds with a second frequency, which relates to an ambient sound in the vehicle.

Control device, vehicle, control method, and computer readable memory medium storing control program

A solar control device controls a solar power generation system having at least one first group including a solar panel and a first DC/DC converter and at least one second group including a second DC/DC converter and a battery. The solar control device includes an electronic control unit that sets an output command value for the second DC/DC converter such that the output command value periodically switches between a first value and a second value that is smaller than the first value, when an output of the second DC/DC converter is equal to or smaller than a threshold value, and determines that the second DC/DC converter is abnormal when the output command value and the output of the second DC/DC converter satisfy a predetermined condition.

Solar control device and method, and vehicle

An information processing system includes processing circuitry, a first storage, and a second storage. The processing circuitry stores the same specific data in the first storage and the second storage. The processing circuitry compares the specific data stored in the first storage with the specific data stored in the second storage. The processing circuitry determines that one of the first storage and the second storage has reached end-of-life on condition that the specific data stored in the first storage and the specific data stored in the second storage do not agree with each other.

Information processing system for vehicle data storage, failure detection, and drive distance consistency management

An information processing device is employed in a vehicle control system and controls access to a shared storage. The information processing device includes a memory and a processor. The processor creates multiple threads. The processor stores, in the memory, access requests for access to the shared storage by applications and adds the access requests for access to a queue such that the access requests are lined up before proceeding with processes in the applications. The processor executes the access requests lined up in the queue using free threads in the order in which the access requests were added to the queue.

Information processing device, information processing method, and storage medium

In a vehicle side portion structure, a vehicle body-side wall surface, which is a wall surface at a side of an aperture lower edge portion of a door lower space, is formed so as to include a first upper surface, a first corner surface, and a first vertical surface that extends substantially downwards from the first corner surface. The door lower space is formed so as to include a corner upper space, which is a space located at a vehicle upper side of the first corner surface, and a first space, which is a space between a door weather strip and the corner upper space. A width in a vehicle up-down direction of the corner upper space is less than a width in the vehicle transverse direction of the first space, and is also less than a width in the vehicle up-down direction of the first space.
