ELECTRONIC CONTROL DEVICE FOR AUTOMOBILE AND DATA COMMUNICATION METHOD

摘要

In the present invention, an electronic control device for an automobile is provided with a non-volatile memory that can electrically erase and write data, and as a result of communication using a communication buffer, the device acquires programs to be written to the non-volatile memory for prescribed sizes. The electronic control device for an automobile receives a program using communication buffers the number of which exceeds the number of communication buffers used by an on-board-state communication environment.
