<P>PROBLEM TO BE SOLVED: To provide a controller, a control system and a control method, allowing efficient use of a memory after completion of products by effective use of a storage area occupied by an inspecting computer program that is stored for inspection of a product with the controller mounted thereon and becomes useless after completion of the product, when transmitting/receiving a computer program executed by the other controller between the controllers to alternate the roles thereof. <P>SOLUTION: In the control system, when an ECU (Electronic Control Unit) including a storage part 11b decides that an inspection program 15b is not likely to be executed in the future, the ECU sets the area occupied by the inspection program 15b in the storage part 11b as an overwrite area. When the ECU receives a control program 13a transmitted from an ECU including a storage part 11a, the ECU stores it in the overwrite area and executes it, so that the control system executes the same processing in the different ECU. <P>COPYRIGHT: (C)2010,JPO&INPIT |
