Management device, functional unit, in-vehicle communication system, and vehicle communication management program

Abstract

To provide a management device, a functional unit, an in-vehicle communication system, and a vehicle communication management program that can more reliably communicate between functional units in an in-vehicle network having a new configuration.SOLUTION: A management device is used for an in-vehicle network that includes one or more in-vehicle functional units. The management device includes: a detection unit that detects addition of a functional unit to the in-vehicle network; a determination unit that determines, based on requirement information indicating requirements necessary for communication between the in-vehicle functional units and the new functional unit, which is transmitted from the new functional unit that is the functional unit whose addition has been detected by the detection unit, whether the in-vehicle functional unit meets the requirements; and an update request unit that transmits update request information requesting update of the in-vehicle functional unit to an external device different from the in-vehicle functional unit when the determination unit determines that the in-vehicle functional unit does not meet the requirements.SELECTED DRAWING: Figure 3

Claims

1. A management device used in an in-vehicle network including one or more in-vehicle function units, A detection unit that detects the addition of a functional unit to the in-vehicle network, A determination unit determines whether the in-vehicle function unit satisfies the requirements based on requirement information transmitted from the new function unit, which is the function unit detected by the detection unit as being added, indicating the requirements necessary for the in-vehicle function unit and the new function unit to communicate. A management device comprising: an update request unit that, if the determination unit determines that the in-vehicle function unit does not meet the requirements, transmits update request information requesting an update to the in-vehicle function unit to an external device different from the in-vehicle function unit.

2. The aforementioned control device further, When the requirement information is received from the new function unit, the system includes an acquisition unit that acquires the function unit information of the in-vehicle function unit for determining the requirement from the in-vehicle function unit, The management device according to claim 1, wherein the determination unit determines whether the in-vehicle function unit satisfies the requirements based on the requirements information and the function unit information.

3. The aforementioned control device further, The vehicle includes an acquisition unit that acquires functional information of the in-vehicle function unit for determining the aforementioned requirements from the external device, The management device according to claim 1, wherein the determination unit determines whether the in-vehicle function unit satisfies the requirements based on the requirements information and the function unit information.

4. The management device according to any one of claims 1 to 3, wherein the requirement is that the version of the software incorporated in the in-vehicle function unit and the version of the software incorporated in the new function unit are the same, or that the version of the software incorporated in the in-vehicle function unit is newer than the version of the software incorporated in the new function unit.

5. A functional unit used in an in-vehicle network that includes one or more in-vehicle functional units, A functional unit that, when added to the in-vehicle network, includes a processing unit that transmits requirement information indicating the requirements necessary for communicating with the in-vehicle functional unit to a management device in the in-vehicle network.

6. A management device used in an in-vehicle network including one or more in-vehicle function units, Equipped with a functional section, The management device detects the addition of the functional unit to the in-vehicle network, The new functional unit, which is the functional unit that has been detected as being added to the in-vehicle network, transmits requirement information, which is information indicating the requirements necessary for the in-vehicle functional unit and the new functional unit to communicate, to the management device. The management device determines whether the in-vehicle function unit satisfies the requirements based on the requirement information received from the new function unit. The management device is an in-vehicle communication system that, when it determines that the in-vehicle function unit does not meet the requirements, transmits update request information to an external device different from the in-vehicle function unit, requesting an update of the in-vehicle function unit.

7. A vehicle communication management program used in a management device used in an in-vehicle network including one or more in-vehicle function units, Computers, A detection unit that detects the addition of a functional unit to the in-vehicle network, A determination unit determines whether the in-vehicle function unit satisfies the requirements based on requirement information transmitted from the new function unit, which is the function unit detected by the detection unit as being added, indicating the requirements necessary for the in-vehicle function unit and the new function unit to communicate. If the determination unit determines that the in-vehicle function unit does not meet the requirements, the update request unit transmits update request information requesting an update to the in-vehicle function unit to an external device different from the in-vehicle function unit. A vehicle communication management program to enable it to function as such.
