  • Patent number: 9889762
    Abstract: An object is to avoid the situation in which the power cannot be turned off. A control system is provided in which the first and second control units are connected. At least one of the first and second control units include: a stop control section for, if a condition for ending a predetermined operation mode is satisfied in that operation mode, performing stop control for having the control system in a low-power-consumption state while communicating with the other control unit; and a mode control section for having a mode undefined state in which the operation mode is instable at restoration from a reset state and for allowing, if a predetermined transition condition for allowing transition into the operation mode is satisfied in the mode undefined state, transition into the operation mode whose transition condition has been satisfied.
