ELECTRONIC CONTROL DEVICE, RETRY POINT IDENTIFICATION METHOD, AND RETRY POINT SPECIFICATION PROGRAM

摘要

This electronic control device (19) is equipped with: a first process flag setting unit (106a) that, when a first process that is a portion of a process involved in rewriting of a program is carried out, sets a first process flag indicating a process state of the first process; a second process flag setting unit (106b) that, when a second process that is another portion of the process involved in rewriting of a program is carried out by a program rewriting unit, sets a second process flag indicating a process state of the second process, after the first process that is a portion of the process involved in rewriting of a program has been carried out; and a retry point specification unit (106c) that, when a portion of the process involved in rewriting of a program has been interrupted, specifies a retry point for restarting the rewriting of the program, on the basis of the first process flag and the second process flag.
