Abstract: A communication system includes interconnected multiple electronic controllers. At least one thereof is a multiple-circuits controller including a first electronic circuit device, a second electronic circuit device, a first power switch, a second power switch, a management frame exchange unit, and a power supply control unit. The first power switch switches between a first connected state and a first disconnected state. The second power switch switches between a second connected state and a second disconnected state. The management frame exchange unit exchanges a management frame including first switching information and second switching information. The power supply control unit switches the first power switch between the first connected state and the first disconnected state according to the first switching information and switches the second power switch between the second connected state and the second disconnected state according to the second switching information.

Abstract: A first device receives an electric power from a battery via an electronic fuse. A second device is connected to the first device to transmit and receive a frame. A third device controls the operation of the electronic fuse. The first and second devices store a diagnosis mask table. The diagnosis mask table defines, for each of communication groups, one or more combinations of a device whose electric power supply via the electronic fuse is cut off, a device which enters a sleep state, and a communication frame that is not received. The third device determines an activation group based on acquired activation trigger information. The third device transmits the communication frame indicating the determined activation group to the first and second devices.

Abstract: A communication system includes a first controller and a second controller connected to each other. The first controller receives electric power from a power source through a power switch. The second controller includes a current detection unit, the management frame obtaining unit, the disconnection determination unit, and the power supply disconnection unit. The current detection unit detects a consumed current value of the first controller. The management frame obtaining unit obtains a management frame including activation information of the first controller. The disconnection determination unit determines, based on the consumed current value and the activation information, whether a predetermined disconnection condition is met. The power supply disconnection unit switches the power switch to a disconnected state when the disconnection determination unit determines that the disconnection condition is met.

Abstract: A communication system includes a first controller and a second controller connected to each other. The first controller receives electric power from a power source through a switch. The second controller includes a current detection unit, a management frame obtaining unit, a state comparing unit, and a diagnostic process executing unit. The current detection unit detects a consumed current value by the first controller. The management frame obtaining unit obtains a management frame including activation information of the first controller. The state comparing unit determines whether a first state based on the consumed current value and a second state based on the activation information of the first controller are inconsistent with each other. The diagnostic process executing unit performs, when the first state and the second state are inconsistent with each other, at least one of (i) storing diagnostic information and (ii) transmitting a notification of the diagnostic information.
