<P>PROBLEM TO BE SOLVED: To provide data rewriting support system and data rewriting support method for a vehicle control device for smoothly achieving data rewriting to the vehicle control device while securing the transfer of necessary data between vehicle control devices connected to a vehicle network. <P>SOLUTION: A program 110 for rewriting is downloaded from a management center 100 to a vehicle C by radio communication. A data-for-rewriting generation control device 220 for converting the program 110 for rewriting downloaded from the management center 100 into data 221 for rewriting is loaded on the vehicle C. Also, a data-for-rewriting transmission control device 230 for monitoring the transmitting situations of data to be transmitted to a CAN bus 250, and for transmitting the data frame of the data 221 for rewriting to the CAN bus 250 adaptively to the data transmitting situations to be monitored is loaded on the vehicle C. <P>COPYRIGHT: (C)2012,JPO&INPIT |
