Claim Text:
1. A control device switching system comprising: a plurality of control devices incorporated in a vehicle and connected to each other via a common communication line, a control device of the plurality of control devices being designated as a processor and the plurality of control devices other than the processor being designated as substitute candidate devices, the processor being configured to perform a data transmission process with the substitute candidate devices, and the substitute candidate devices being configured to perform the data transmission process while the processor stops the data transmission process, wherein: the processor comprises substitute transmission acceptability determining code and substitution request transmitting code; the substitute transmission acceptability determining code causes the processor to determine whether or not each of the substitute candidate devices is in a state to perform the data transmission process based on an importance level of a process that is currently executed by each of the substitute candidate devices, and assign the data transmission process to one of the substitute candidate devices based on a result of the determination; the substitution request transmitting code causes the processor to transmit a substitution request to one of the substitute candidate devices that is assigned to perform the data transmission process before the processor stops the data transmission process; and each of the plurality of substitute candidate devices comprises substitute transmission code causing respective one of the plurality of substitute candidate devices to perform the data transmission process in response to the substitution request being received from the processor.
