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 record control apparatus controls record of a data item in one or more record sections. The record control apparatus includes: a data acquisition section that acquires the data item having multiple types; a data storage section that stores in the record section, the one or more data items matching a record condition prepared in advance among the acquired data item having multiple types; and a condition change section that defines the record condition as an old record condition, and sets so that the data storage section utilizes a new record condition in place of the old record condition when receiving the new record condition different from the old condition from an outside.

Abstract: A service cooperation system enables a use of a function provided by an in-vehicle apparatus or an external apparatus as a service. The service cooperation system for the vehicle includes a service interface, a local service bus, a service bus, and an integrated application. The service interface of a subject apparatus provides the service generated in the subject apparatus to a different apparatus. The local service bus transmits and receives a message between the service interface of the subject apparatus and the service interface of the different apparatus. The service bus is virtually configured by a connection of the local service bus of the subject apparatus and the local service bus of the different apparatus. The integrated application functions as the application and enables a cooperated use of an in-vehicle service and an external service through the service bus.

Abstract: A vehicular ECU (electronic control unit) is any one of a plurality of vehicular ECUs connected to an in-vehicle network in a vehicle and includes: a service interface, a service bus, and a service manager. The service interface issues a request of service that uses a function installed in a different vehicular ECU based on a request from the application, and makes the application generate a service as a response to a request of service from the different vehicular ECU. The service bus transmits and receives a message corresponding to a request of service and a response by using a predetermined protocol between the service interfaces of the vehicular ECU and the different vehicular ECU. The service manager achieves the service to be dynamically and interoperably used by managing a position of the service.

Abstract: A center prescribes, to a subject vehicle, a collection condition for vehicle data through wireless communication. An instruction executing section reads in and executes an instruction described as the collection condition. A determination section determines whether environment information prescribed by the collection condition agrees with the vehicle environment of the subject vehicle. A communication section delivers, to the center, the vehicle data of a time at which the agreement is established.
