Abstract
An object is to shorten a time required for reprogramming of a control device including a single-bank microcomputer. An ECUis a control device including a first microcomputerand a second microcomputerthat execute a program stored in a rewriting areain which a memory bank is configured as a single bank. The second microcomputerincludes a preprocessing unitthat performs preprocessing on a rewriting programin reprogramming processing of rewriting the program stored in the rewriting areainto the rewriting program, and a transmission unitthat transmits the preprocessed rewriting programto the first microcomputer. The first microcomputerincludes a reception unitthat receives the rewriting programtransmitted from the second microcomputer, and a writing unitthat writes the received rewriting programin the rewriting area
