Abstract: A communication system includes: a first control device receiving electric power supply from a power source via an electronic fuse; a second control device connected to the first control device for data communication; and a management device connected to the first and second control devices for data communication and controlling the electronic fuse. The management device performs at least one of: transmitting power source pre-cutoff notification information to the second control device notifying that the electric power supply will be cut off before turning off the electronic fuse; and transmitting power source post-cutoff notification information notifying that the electric power supply has been cut off after turning off the electronic fuse.

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 relay device in a communication system receives a plurality of wakeup frames from one or more than one communication device connected to each bus of a plurality of buses via a corresponding port. The relay device obtains an aggregated wakeup pattern by aggregating information on an operating mode of each communication device included in the plurality of wakeup frames so as to include predetermined information to be transmitted and received and reduce the number of wakeup patterns. By using the aggregated wakeup pattern obtained by aggregating the information on the operating mode, a wakeup frame for transmission to each bus via the corresponding port is prepared.

Abstract: A communication system, in which a plurality of nodes communicate with each other according to a communication protocol, which wakes up some of the plurality of nodes when a communication frame containing specific start information occurs on or is transmitted to the communication bus, includes a master node determines, for each of slave nodes, a start condition, which is a condition for transition of a subject node from a sleep state to a normal state. The master node transmits, to the communication bus, the determined start condition tailored for each of the slave nodes for a reception thereof by each of the slave nodes.
