Abstract
Official abstract text for this publication.
An on-vehicle network system includes, for each of a plurality of zones defined in a vehicle, a zone control unit, a power distributor connected to an on-board battery, and a plurality of electronic devices supplied with power from the power distributor via a common power supply line. Each of individual relays is interposed between one of the electronic devices and a body ground of the vehicle to individually turn on and off connection between the one of electronic device and the body ground based on a control signal from the zone control unit.
First claim
Opening claim text (preview).
1 . An on-board network system comprising: for each of a plurality of zones defined in a vehicle, a power distributor connected to an on-board battery, a plurality of electronic devices supplied with power from the power distributor via a common power supply line, and zone control circuitry configured to control the plurality of electronic devices; and individual relays each between one of the electronic devices and a body-ground of the vehicle to individually turn on and off connection between the one of the electronic devices and the body-ground based on a control signal from the zone control circuitry. 2 . The on-board network system of claim 1 , wherein the electronic devices that are turned on and off at a common timing in each of the zones are collectively connected to the body-ground via one of the individual relays. 3 . The on-board network system of claim 2 , wherein the vehicle includes a body-ground connector electrically connected to a metal body of the vehicle and connectable to a ground wire of each of the electronic devices, and each of the individual relays is built in the body ground connector. 4 . The on-board network system of claim 1 , wherein the vehicle includes a body-ground connector electrically connected to a metal body of the vehicle and connectable to a ground wire of each of the electronic devices, and each of the individual relays is built in the body ground connector. 5 . A vehicle comprising: a metal body; an on-board battery; and an on-board network system that includes for each of a plurality of zones defined in a vehicle, a power distributor connected to the on-board battery, a plurality of electronic devices supplied with power from the power distributor via a common power supply line, and zone control circuitry configured to control the plurality of electronic devices, and individual relays each between one of the electronic devices and the metal body of the vehicle to individually turn on and off connection between the one of the electronic devices and the metal body based on a control signal from the zone control circuitry 6 . The vehicle of claim 5 , wherein the electronic devices that are turned on and off at a common timing in each of the zones are collectively connected to the metal body via one of the individual relays. 7 . The vehicle of claim 5 , wherein the vehicle includes a connector electrically connected to the metal body of the vehicle and connectable to a ground wire of each of the electronic devices, and each of the individual relays is built in the body ground connector. 8 . The vehicle of claim 6 , wherein the vehicle includes a connector electrically connected to the metal body of the vehicle and connectable to a ground wire of each of the electronic devices, and each of the individual relays is built in the body ground connector.
