Abstract: 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.

Abstract: An information processing device configured to update stored content of a storage device of a vehicle includes an execution device, a first storage unit, and a second storage unit. The execution device is configured to store data received from a different controlling device in a first storage area of the second storage unit, and request, when a prescribed update condition is met, writing of the data stored in the first storage area to the storage device, and thereafter notify the different controlling device that writing of the data has been completed. The execution device is configured to store, when writing of data to the storage device is requested, the data stored in the first storage area in the second storage area of the second storage unit, and thereafter write the data stored in the second storage area to the storage device.

Abstract: A storage management device for a vehicle includes a processor and a memory. The processor is configured to store, in the memory, data corresponding to an operation of each vehicle on-board system in which one of multiple functional safety levels is set in advance. The memory includes a first partition and a second partition allocated in advance. The first partition is configured to store data corresponding to an operation of a vehicle on-board system for which a functional safety level lower than a predetermined specific level is set. The second partition is configured to store data corresponding to an operation of a vehicle on-board system for which a functional safety level higher than or equal to the specific level is set.

Abstract: 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.

Abstract: An information processor and an information processing method are provided. Processing circuitry receives a data piece from another controller to manage a storage device provided in a vehicle. The data piece includes a character string. The character string includes a specific character and one or more start direction characters. The one or more start direction characters are one or more characters positioned in a start direction relative to the specific character in the character string. The processing circuitry writes only the one or more start direction characters to the storage device to update a stored content of the storage device.

Abstract: 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.
