Microcontroller and watchdog operation synchronization method for vehicle control device, involves operating watchdog based on time period elapsed after booting up to resetting operation of microcontroller

摘要

The microcontroller is reset if the watchdog is not operated according to a temporal pattern of the microcontroller. The time period elapsed after booting up the microcontroller up to a resetting operation is determined. The watchdog is operated based on the determined time period. Independent claims are also included for the following: (a) Storage device comprising program for synchronizing operation of microcontroller and watchdog; (b) Control device
