Abstract
A controller includes a communication controller having a communication area and a normal control controller having a normal control area, and is provided in a vehicle. The controller stores an update program, which is transferred via an external communication mechanism from an external server to a vehicle, in the communication controller. If it is determined, based on manipulation of a key switch to a stop position, that updating can be performed, the controller transfers the update program stored in the communication controller to the normal control controller and performs rewriting. A program is thereby reliably rewritten within a short period of time to improve work efficiency.
