<p>PROBLEM TO BE SOLVED: To easily perform a return operation in a centralized control system for on-vehicle apparatuses. SOLUTION: When a return operation for cancelling an operating instruction is given, an operation control part 11 investigates whether a switching of an image plane was performed or not by means of the cancelled operating instruction, and when the switching is performed, the operation control part determines the latest operating instruction by which the image plane was switched up to that time. The operation control part instructs group control parts 16 to 18 which executed the operating instruction, to display the image plane. Referring to the image plane-transition history, the group control parts display the image plane before the cancelled operating instruction was executed, on a display part 8a.</p> |
