Provided are an electronic control device and a microcomputer control method not only enabling smooth transmission and reception of signals by using a plurality of microcomputers but also capable of achieving, with a simpler configuration, reduction of power consumed by the microcomputers. As a mode for reducing power consumption, the electronic control device brings microcomputers from which a sleep request has been issued into a sleep state. The electronic control device is equipped with a low power consumption mode for bringing a communication bus driver into the sleep state after all microcomputers constituting the electronic control device have been transferred into the sleep state. |
