Classification: CPC G  B | IPC B  G

Claim 14:
15. A vehicle controller that manages and executes a plurality of functions in units of predetermined function group, the controller comprising:
a partition updater that dynamically changes a function group; and
a mode changer that receives a function group change implementation request for instructing change of a function group in response to a change in an operation environment of a system from an outside of the controller, and, in response to the function group change implementation request, permits execution of the function group changed by the partition updater;
a first vehicle controller; and
a second vehicle controller, wherein
the first vehicle controller is the controller according to claim 1, and
the second vehicle controller issues the function group change implementation request and transmits the function group change implementation request to the first vehicle controller; and wherein
before issuing the function group change implementation request, the second vehicle controller issues a function group change preparation request for requesting preparation for change of the function group and transmits the function group change preparation request to the first vehicle controller,
the mode changer of the first vehicle controller receives the function group change preparation request from the second vehicle controller, acquires change information describing matters to be changed from an outside of the controller in response to the function group change preparation request, and instructs the partition updater to change partition of the function group, and
the partition updater of the first controller resets partitioning of the function group on a basis of the change information.
