Abstract: A vehicle information communication system includes a center apparatus and a vehicle apparatus that includes a group of electronic control units (ECUs) and that sends vehicle configuration information including configuration information on the group of ECUs mounted in the vehicle to the center apparatus via wireless communications. The center apparatus performs a first determination of whether the vehicle configuration information received from the vehicle apparatus matches approved-configuration information registered in an approved-configuration database, and performs a second determination of whether software update data for at least one ECU of the group of ECUs mounted in the vehicle exists in an update database. When both the first and second determinations are true, the center apparatus sends the software update data for at least one ECU of the group of ECUs mounted in the vehicle to the vehicle apparatus via the wireless communications.

Abstract: A vehicular system includes a master ECU, a first slave ECU, and a second slave ECU. The second slave ECU transmits a storing request to the master ECU on detection of a malfunction. The master ECU transmits a storing instruction for causing diagnostic information to be stored, on reception of the storing request. The first slave ECU generates diagnostic information on the first slave ECU, on reception of the storing instruction from the master ECU. The first slave ECU further stores the generated diagnostic information in a retention storage medium. The retention storage medium is configured to retain validity determination information in a condition where the first slave ECU is not supplied with electric power source.

Abstract: A vehicle communication system is configured to receive vehicle configuration information from a vehicle and determine whether there is campaign information, generate campaign notification information for the vehicle, manage a generation state of the campaign information, and deliver the campaign notification information to the vehicle. The vehicle communication system includes a center apparatus in which an application program that implements functions employs a serverless architecture. When an in-vehicle system transmits a first request including vehicle information to the center apparatus, the center apparatus transmits an intermediate response including a job ID to the in-vehicle system. When receiving the intermediate response, the in-vehicle system transmits a response request of a final response corresponding to the first request to the center apparatus as a second request to which the job ID is assigned.

Abstract: A center device that manages data to be written in an electronic control device and performs, by an application program, functions to transmit update data to a vehicle by wireless communication is provided. An application program implementing at least one of the functions adopts a serverless architecture. The application program is activated upon occurrence of an event and is dynamically allocated with a resource in an on-demand manner for execution of a code of the application program. The resource is released when the execution of the code is terminated. The center device is configured to receive vehicle configuration information and determine whether there is campaign information; generate campaign notification information; manage a generation state of the campaign notification information; and distribute the campaign notification information.

Abstract: A vehicular electronic control device comprises: a microcontroller including a nonvolatile memory which can store software including programs and data, the nonvolatile memory including a first area and a second area as memory areas, and a control unit which includes a first core and a second core and which executes, on at least one of the first and second cores, a rewriting program for rewriting software; and an external storage which is provided externally to the microcontroller and which temporarily stores reprogramming data for updating software. If the control unit determines a rewrite of its own software on the basis of specifications data, the control unit uses a memory area in the external storage to rewrite the software stored in the nonvolatile memory.
