Distributed network management system and method for a vehicle

A distributed network management system for a vehicle, comprising:

• a plurality of electronic control units, wherein the electronic control units are inter-connected by a distributed network;
• a portable electronic control unit detachably connected to the electronic control units by the distributed network;
• a plurality of data configuration modules, wherein each of the data configuration modules is disposed on each of the electronic control units and the portable electronic control unit, and each of the data configuration modules is configured for performing a re-configuring action to a plurality of network messages;
• a plurality of data definition modules, wherein each of the data definition modules is disposed on each of the electronic control units and the portable electronic control unit and is connected to each of the data configuration modules, and each of the data definition modules is configured for performing a pre-defining action corresponding to the network messages;
• a plurality of distributed node status broadcast modules, wherein each of the distributed node status broadcast modules is disposed on each of the electronic control units and the portable electronic control unit, and each of the distributed node status broadcast module is configured for enabling the portable electronic control unit to perform a task assigning action;
• a plurality of task transformation modules, wherein each of the task transformation modules is disposed on each of the electronic control units and the portable electronic control unit, and the portable electronic control unit performs a task transferring action through one of the electronic control units;
• a plurality of task overload modules, wherein each of the task overload modules is disposed on each of the electronic control units and the portable electronic control unit, and the portable electronic control unit performs a task overloading action through one of the task overload modules;
• and
• a plurality of task load balance modules, wherein each of the task load balance modules is disposed on each of the electronic control units and the portable electronic control unit, and the portable electronic control unit performs a task load balancing action through one of the task load balance modules;
• wherein the portable electronic control unit is selectable as a leading node to perform the task assigning action to order the electronic control units through one of the distributed node status broadcast modules;
• when one of the electronic control units is failed and cannot perform any tasks, the portable electronic control unit selected as the leading node performs the task transferring action, the task overloading action and the task balancing action to order the electronic control unit selectable as an idle node to execute the tasks of the failed electronic control unit through the task transformation modules, the task overload modules and the task balance modules of the portable electronic control unit selected as the leading node.

A distributed network management method for a vehicle, the distributed network management method comprising:

• a data configuration step for preforming a re-configuring action to a plurality of network messages transmitted through a plurality of nodes;
• a data definition step for performing a pre-defining action corresponding to the network messages;
• a distributed node status broadcast step for selecting one of the electronic control units to perform a task assigning action;
• a task transformation step for selecting one of the electronic control units to perform a task transferring action;
• a task overload step for selecting one of the electronic control units to perform a task overloading action;
• and
• a task load balance step for selecting one of the electronic control units to perform a task load balancing action.

A distributed network management method for a vehicle, the distributed network management method comprising:

• a first step for preforming a re-configuring action and a pre-defining action to a plurality of network messages transmitted through a plurality of nodes;
• a second step for defining a leading node form the nodes;
• a third step for detecting a failed node from the nodes;
• a fourth step for defining at least one idle node by the leading node according to an available task load of each of the nodes, thereby assigning a task of the failed node to the idle node;
• a fifth step for defining an overload node by the leading node according to the available task load of each of the nodes;
• and
• a sixth step for equally distributing an overload task of the overload node to the leading node and each of the other nodes;
• wherein the nodes are a plurality of electronic control units that are capable of transmitting network messages with each other.
