Vehicular electronic control unit and vehicular service management system
First Claim
1. A vehicular ECU (electronic control unit) that is any one of a plurality of vehicular ECUs connected to an in-vehicle network in a vehicle, the vehicular ECU performing a predetermined function by using an application that is installed, the vehicular ECU coordinating with a different vehicular ECU among the plurality of vehicular ECUs excluding the vehicular ECU,the vehicular ECU comprising:
- a service interface that issues a request of service that uses a function installed in the 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;
a service bus that transmits and receives a message correspondingly to a request of service and a response by using a predetermined protocol between the service interface of the vehicular ECU and the service interface of the different vehicular ECU; and
a service manager that achieves the service to be used dynamically and interoperably by managing a position of the service.

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.

5. A vehicular service management system comprising:
-
a plurality of vehicular ECUs (electronic control units) that are connected to an in-vehicle network in a vehicle, each of the vehicular ECUs performing a predetermined function by using an application; and a gateway that is connected to the in-vehicle network and routes information between the vehicular ECUs, wherein a subject vehicular ECU being any one of the vehicular ECUs cooperates with a different vehicular ECU among the vehicular ECUs excluding the subject vehicular ECU, the subject vehicular ECU includes; a service interface that issues a request of service that uses a function installed in the 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; and a service bus that transmits and receives a message correspondingly to a request of service and a response by using a predetermined protocol between the service interface of the subject vehicular ECU and the service interface of the different vehicular ECU, wherein the gateway includes a service manager that achieves the service to be dynamically and interoperably used by managing a position of the service. - View Dependent Claims (6, 7, 8, 9, 11)
