Vehicle control apparatus

A vehicle control apparatus comprising:

• two or more computing processors;
• a storage area of a storage apparatus that is provided for each of the computing processors and in which a program to be executed by the computing processor is stored;
• an in-vehicle communication channel that is utilized for communication among the computing processors;
• an outside-communicator-that receives, from an outside, updating-program information related to an updating program for updating a program to be executed by the computing processor and data related to the updating program;
• a program sorter that sorts, based on the updating-program information, the updating program into an existing program already existing in the storage area for the computing processor excluding the computing processor that executes the updating program and into a new program that does not exist in any storage areas for the computing processors;
• a new-program writer that receives, from the outside, data for the new program obtained through sorting by the program sorter, by way of the outside-communicator, and then writes the data in the storage area for the computing processor that executes the updating program, by way of the in-vehicle communication channel;
• and
• an existing-program writer that reads data for the existing program obtained through sorting by the program sorter, from a transfer-source storage area by way of the in-vehicle communication channel, and then writes the data for the existing program in the storage area for the computing processor that executes the updating program, by way of the in-vehicle communication channel.
