Problems solved by technology

[0006] However, when the number of lower-level devices that require redundancy such as the automatic driving function increases, if power is directly supplied from each power supply line to each lower-level device through separate wiring as before, the wiring will become complicated.

Embodiment approach

[0018] Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

[0019]

[0020] figure 1 A schematic diagram of the network system 1 according to this embodiment is shown. This network system 1 can be mounted on vehicles such as a hybrid vehicle (HV) and an electric vehicle (EV).

[0021] The network system 1 in this embodiment includes a power supply system 50 that redundantly includes a first power supply system 51 that uses a first battery 54 as a power supply to supply power and a second battery 55 that uses a second battery 55 as a power supply to supply power. Two power supply systems 52 . The first battery 54 and the second battery 55 employ secondary batteries such as lithium ion batteries configured to be chargeable and dischargeable. The first battery 54 can be connected to an alternator (ALT) or other batteries via a DCDC converter (not shown). A relay 53 (mechanical relay, semiconductor relay, etc.) is...

Abstract

A network system includes: an electric power system including a first power supply system and a second power supply system; a higher-level device connected to a first power supply of the first power supply system and a second power supply of the second power supply system; a first intermediate device connected to the first power supply of the first power supply system and configured to control supply of an electric power to a first lower-level device; and a second intermediate device connected to the second power supply of the second power supply system and configured to control supply of an electric power to a second lower-level device that is a redundant component for the first lower-level device.

Description

technical field [0001] The present invention relates to a network system mounted on a vehicle or the like. Background technique [0002] A vehicle is equipped with a plurality of devices such as electronic devices and electronic components called ECUs (Electronic Control Units). These devices share and perform various functions of the vehicle. [0003] As a network system including a plurality of devices, Japanese Patent Laid-Open No. 2015-067187 discloses a network system having a tree-type connection topology. In the network system described in Japanese Patent Application Laid-Open No. 2015-067187, a plurality of relay ECUs as upper nodes are connected to each other through communication lines, and each relay ECU is connected to a plurality of lower devices as lower nodes. [0004] In a network system such as Japanese Patent Application Laid-Open No. 2015-067187, it is considered that a high-level node is a high-performance device that integrates functions for vehicle co...
