Vehicle-mounted network system and management apparatus for the same

摘要

A vehicle-mounted network system includes a plurality of electronic control units (ECUs) communicatively connected to a communication path of a vehicle-mounted network, each of which is configured to selectively perform a normal mode of operation and a sleep mode, and a management apparatus. The plurality of ECUs are configured to be individually powered on and off by a power supply relay of the management apparatus. The management apparatus is configured to acquire information indicative of a vehicle situation and determine a scene from the acquired information, determine control contents for powering on or off at least one specific ECU, of the plurality of ECUs, corresponding to the determined scene, if any, and power on or off the at least one specific ECU based on the determined control contents.

1. A vehicle-mounted network system comprising:
a plurality of electronic control units (ECUs) communicatively connected to a communication path of a vehicle-mounted network, each of the ECUs being configured to selectively perform a normal mode of operation, in which the functionality of the ECU is not restricted, and a sleep mode, in which the functionality of the ECU is restricted; and a management apparatus communicatively connected to the communication path, wherein the management apparatus comprises: a power supply relay including a plurality of switches provided along a plurality of power delivery paths, one for each of the plurality of power delivery paths, each of the power delivery paths being connected to at least one of the plurality of ECUs through a corresponding one of the switches, whereby the at least one ECU can be powered on and off by turning on and off the corresponding switch; a scene determination unit configured to acquire information indicative of a vehicle situation and determine a scene from the acquired information; a control content determination unit configured to determine control contents for powering on or off at least one specific ECU, of the plurality of ECUs, corresponding to the scene determined by the scene determination unit, if any; and a control unit configured to power on or off the at least one specific ECU by using the power supply relay based on the control contents determined by the control content determination unit.
