Information processing apparatus, control system, system, information processing method, control method and computer-readable storage medium

A communication apparatus is provided in a movable object, and communicates with an external server. The communication apparatus includes a communication control unit for controlling communication with the server, and controlling communication with a movable object control unit controlling the movable object and communication with an update control unit controlling program update of the movable object control unit. The communication control unit performs, when control on the movable object control unit is to be performed from the server, control to receive a first startup request and a command for the movable object control unit from the server, start up and control the movable object control unit, and performs, when control related to program update of the movable object control unit is to be performed from the server, control to receive a second startup request for the update control unit from the server, and start up the update control unit.

Communication apparatus, movable object, control system, server, communication control method

A control system includes a movable object control unit configured to control a movable object, an update control unit configured to control a program update of the movable object control unit, and a communication path that is a path for the movable object control unit and the update control unit to perform an information communication, a path that is connected to an external diagnosis apparatus configured to perform a diagnosis of the movable object control unit and used for transmitting information of the movable object to the external diagnosis apparatus and the communication path are at least partially in common, and the control system includes a restriction control unit configured to restrict, when the program update and the diagnosis of the movable object control unit by the external diagnosis apparatus are to be performed, one of the diagnosis by the external diagnosis apparatus and the program update.

Control system, movable object, control method, and computer readable storage medium

A program update control apparatus comprises a rewriting control unit for performing control over rewriting of a program executed by a mobile object control unit for controlling at least part of a mobile object with a new program, a retrieving unit for retrieving information related to the new program and a power amount required for the rewriting from an external apparatus, and a power source information retrieving unit for retrieving a remaining capacity of a battery of the mobile object used for the rewriting, wherein the rewriting control unit starts the rewriting based on information related to a power amount required for the rewriting, the power source information retrieving unit retrieves a remaining capacity of the battery during the rewriting, and the rewriting control unit determines whether to continue the rewriting based on a remaining capacity of the battery retrieved and the power amount required for the rewriting.

Program update control apparatus, program update control method, and computer-readable storage medium

A program update control apparatus comprises a rewriting control unit configured to perform control of rewriting a program, which is executed by a mobile object control unit configured to control at least a part of a mobile object, to a new program; and an acquisition unit configured to acquire the new program from an external apparatus, wherein the rewriting control unit is configured: before starting the rewriting, to request a user to consent to execution of the rewriting, and to hold consent information, which indicates that the user has consented to execution of the rewriting, and when activated in response to a power supply being on, to cause the rewriting to be executed without requesting the user to consent to execution of the rewriting, on the condition that the consent information is held.

Program update control apparatus, program update control method and computer-readable storage medium

An OTA manager, when an activation switch of a vehicle is OFF, transmits a unique identifier of each electronic control unit acquired before the activation switch was switched from ON to OFF to an OTA server via a communication line and receives update data from the OTA server via the communication line, and after the activation switch was switched from OFF to ON, the OTA manager makes a comparison between the identifiers transmitted to the OTA server before the activation switch was switched from OFF to ON and the identifiers acquired after the activation switch was switched from OFF to ON.

Vehicle and software update method

A software update device is provided with an update control unit that that performs a software update using a new software version supplied over a network. If a software update is to be performed for a first electronic control device and a second electronic control device that operates in cooperation with the first electronic control device, the update control unit performs the software update for the first electronic control device such that the first electronic control device after the software update has been performed is capable of selectively executing the operation logic of a first new software version and the operation logic of a first old software version.

Software update device, vehicle, and software update method

A software update device is provided with an update control unit that performs a software update using a new software version supplied over a network. The update control unit installs a first new software version on a first electronic control device prior to installing a second new software version on a second electronic control device, and activates the first new software version installed on the first electronic control device either after activation of the second new software version installed on the second electronic control device has started or after it is ascertained that activation of the second new software version installed on the second electronic control device has been normally completed.
