Electronic control unit for controlling internal combustion engine of motor vehicle, has loading unit that loads subroutine in accordance with detected sub-process in rewritable memory

摘要

The electronic control unit (1) has a program-control unit to program the control program. The program is loaded in the rewritable memory (4) when a starting condition is satisfied. The programming process is provided with sub-processes that are executed in order to program the control program. The detecting unit detects the sub-process to be executed at the present time after the programming start condition is satisfied, until a termination condition is satisfied. The loading unit loads the subroutine in accordance with the detected sub-process in the rewritable memory. An independent claim is included for method for programming control program in rewriteable non volatile memory of electronic control unit.
