Abstract
An object of the present invention is to provide a technology that enables second control software to continue processing using a peripheral circuit even in a situation where an abnormality related to first control software occurs. An electronic control device includes a memory () that stores the first control software and the second control software, a CPU () that executes the first control software and the second control software, and a peripheral circuit () used by the first control software and the second control software. The memory further includes a first buffer () and a second buffer (). The CPU interrupts at least one of the processing of storing first peripheral transmission information in the first buffer and the processing of transmitting the first peripheral transmission information to the peripheral in a specific situation in which the abnormality related to the first control software occurs.
