1. a vehicle-mounted data storehouse distribution node, it comprises:

  • Input/output device, for inputting data from coupled electronic control unit to it, and to described electronic control unit output data;

    Memory, for being deposited with together vehicle-mounted data storehouse as attribute value data using the data from described electronic control unit to its input;

    Data output device, be deposited with the described attribute value data in described vehicle-mounted data storehouse by use, at required time, to the data that output is necessary in described electronic control unit, described one in wherein said electronic control unit is different from described electronic control unit from described attribute value data to described vehicle-mounted data storehouse that input;

    Via vehicle-mounted lan network vehicle-mounted LAN communicator connected to one another, for inputting described attribute value data from other vehicle-mounted data storehouse distribution node and exporting described attribute value data to other vehicle-mounted data storehouse distribution node;

    AndVehicle-mounted data storehouse synchronizer, for by corresponding to being recorded in the described vehicle-mounted data storehouse in described memory via described input/output device to the described attribute value data of the data of its input, via described vehicle-mounted LAN communicator, described attribute value data is sent to vehicle-mounted lan network, and in the time that described vehicle-mounted data storehouse synchronizer receives described attribute value data via described vehicle-mounted LAN communicator from described vehicle-mounted lan network, described attribute value data is deposited with in described vehicle-mounted data storehouseWherein, in described memory, record output time table is set, be wherein provided with the data output time when identifying wait the identifying information of the described attribute value data of exporting and output data based on described attribute value data;

    Described vehicle-mounted data storehouse distribution node further comprises output time setting device, for requiring and require to upgrade described output time according to described output table is set from described electronic control unit input and output via described input/output device.
