Abstract
The invention provides an automobile ECU network node online configuration method and a system. The automobile ECU network node online configuration method comprises the following steps: an identification step: existence of all automobile-mounted ECUs is identified by data identifiers; and a reading step: existence of the automobile-mounted ECUs on an automobile-mounted network is accurately judged by all the automobile-mounted ECUs via reading the data identifiers stored by the automobile-mounted ECUs. Beneficial effects are that: in the automobile ECU network node online configuration method and the system, the optional mounting state of the ECUs which can be optionally mounted is accurately identified without additionally arranging standard configuration ECU part numbers via the ECU network node online configuration; besides, the ECU network node online configuration can be automatically realized without manual judgment operation.
Description
Technical field
The present invention relates to technical field of automotive electronics, relate in particular to automobile ECU network node Configuration Online method and system.
Background technology
Current domestic automobile product (especially passenger car), in the selection of automobile bus, CAN bus has become gradually main flow and has been used; In order to meet the diversified demand of client, certain carload product configuration, often exists choosing to fill the situation of even a plurality of ECU modules simultaneously.Have between the ECU of information interaction, the ECU of standard configuration must accurately identify the whether selected dress of ECU of choosing dress, just can accurately judge whether the information interaction behavior between Ying Yuxuan dress ECU.Current common way is: increases and selects the number of spare parts that has the standard configuration ECU module of information interaction between dress ECU, and corresponding one by one to guarantee standard configuration ECU and choosing dress ECU.
But by increasing the number of spare parts of corresponding standard configuration ECU, brought certain problem also to the links such as research and development, logistics, production of automobile production enterprise simultaneously:
The increase of A, ECU number of spare parts, has increased the cost in research and development of products stage.
The logistics cost of B, increase enterprise.
C, brought misloading risk to Automobile Enterprises production line.
Summary of the invention
In order to solve the problems of the prior art, the invention provides a kind of automobile ECU network node Configuration Online method.
The invention provides a kind of automobile ECU network node Configuration Online method, comprise the steps:
Identification of steps: all vehicle-mounted ECU are identified to it with data identifier and whether exist;
Read step: each vehicle-mounted ECU accurately judges that by reading the data identifier of self storing whether the vehicle-mounted ECU on In-vehicle networking exists.
As a further improvement on the present invention, in described identification of steps, with the arbitrary position of the arbitrary byte of data identifier, identify vehicle-mounted ECU and whether exist.
As a further improvement on the present invention, after scanning VIN code, from Production database, automatically obtain the configuration information of this car, and write in network node data identifier.
The present invention also provides a kind of automobile ECU network node Configuration Online system, comprising:
Identification module: whether exist for all vehicle-mounted ECU are identified to it with data identifier;
Read module: accurately judge that by reading the data identifier of self storing whether the vehicle-mounted ECU on In-vehicle networking exists for each vehicle-mounted ECU.
As a further improvement on the present invention, in described identification module, with the arbitrary position of the arbitrary byte of data identifier, identify vehicle-mounted ECU and whether exist.
As a further improvement on the present invention, after scanning VIN code, from Production database, automatically obtain the configuration information of this car, and write in network node data identifier.
The invention has the beneficial effects as follows: in the present invention, by ECU network node Configuration Online, realize in the situation that not increasing standard configuration ECU Part No., accurately identify the choosing dress state of optional dress ECU; And can automatically realize ECU network node Configuration Online, without artificial decision operation.
Accompanying drawing explanation
Fig. 1 is that a certain configuration of car load of the present invention exists the network node Configuration Online schematic diagram while selecting dress ABS.
Embodiment
The invention discloses a kind of automobile ECU network node Configuration Online method, comprise the steps:
Identification of steps: all vehicle-mounted ECU are identified to it with data identifier and whether exist;
Read step: each vehicle-mounted ECU accurately judges that by reading the data identifier of self storing whether the vehicle-mounted ECU on In-vehicle networking exists.
In described identification of steps, with the arbitrary position of the arbitrary byte of data identifier, identify vehicle-mounted ECU and whether exist.
After scanning VIN code, from Production database, automatically obtain the configuration information of this car, and write in network node data identifier.
The invention also discloses a kind of automobile ECU network node Configuration Online system, comprising:
Identification module: whether exist for all vehicle-mounted ECU are identified to it with data identifier;
Read module: accurately judge that by reading the data identifier of self storing whether the vehicle-mounted ECU on In-vehicle networking exists for each vehicle-mounted ECU.
