Abstract
The utility model discloses a CAN-LIN network diagnosis interface of a vehicle, which comprises a plurality of connection ports for being directly connected with a corresponding CAN-LIN network by cables. The CAN-LIN network diagnosis interface of the vehicle can break through the restriction of a built-in systems interface (BSI) gateway, is used for monitoring the communication between a BSI and the downstream electronic control units (ECUs) of the BSI and the communication between every two ECUs and is convenient for technical personnel to analyse the type of the vehicle.
Description
Technical field
The utility model relates to vehicle CAN-LIN network diagnosis device, relates in particular to a kind of vehicle CAN-LIN network diagnosis interface.
Background technology
For French Peugeot Citroen PSA, along with the upgrading of vehicle, new network is constantly introduced, and network function is complicated day by day, has brought new challenge for the research and development analytical work of new model.At current AEE2010 (Electronics and Electrical Architecture, electric framework) in, two CAN (Controller Area Network is arranged, controller local area network) High Speed Network, article three, CAN low speed net, and two LIN (Local Interconnect Network, local internet) net (LIN2.X), described CAN High Speed Network comprises IS (English Inter-Systeme, interactive system) net and LAS net, described CAN low speed net comprises CAR (French Carrosserie, vehicle body) net, CONF (French Confort, comfortable) net and INFODIV (French Information Divers, entertainment information) net.Want on vehicle, to research and develop new product, just must be equipped with the network diagnosis interface, monitor communication on each network by network diagnosis, so that aforementioned CAN/LIN network data is analyzed based on AEE2010.
Existing network diagnosis interface is generally OBD (On-Board Diagnostics, On-Board Diagnostics (OBD)) diagnose interface, and as shown in Figure 1, this OBD diagnose interface is by BSI (French
De Servitude Intelligent, artificial intelligence is waitd upon the clothes box) be connected with each network, can only realize diagnostic function that CANDiag net (transmit CAR net, CONF net and INFODIV netting index according to) and IS are netted as gateway by BSI, and can't monitor the communication between BSI and its downstream ECU (Electronic Control Unit, electronic control unit) and each ECU.In addition, its butt joint is proprietary connector, is monopolized by external individual diagnosis equipment supplier for a long time, costs an arm and a leg.
Therefore, demand urgently providing a kind of improved vehicle CAN-LIN network diagnosis interface to overcome above-mentioned defective.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of vehicle CAN-LIN network diagnosis interface, and it can break through the restriction of BSI gateway, and the communication between monitoring BSI and its downstream ECU and each ECU makes things convenient for the analysis of technical staff to vehicle.
In order to solve the problems of the technologies described above, the utility model provides a kind of vehicle CAN-LIN network diagnosis interface, and it comprises: be used for passing through the direct-connected a plurality of connectivity ports of cable with corresponding CAN-LIN network.
Compared with prior art, vehicle CAN of the present utility model-LIN network diagnosis interface directly links to each other the overall network on the vehicle by cable with corresponding connectivity port, thereby can realize diagnostic function to overall network, and can break through the restriction of BSI gateway, communication between monitoring BSI and its downstream ECU and each ECU makes things convenient for the analysis of technical staff to vehicle.In addition, it is simple in structure, is convenient to make.
Further, described connectivity port comprises: first connectivity port, second connectivity port that is used for being connected with another local internet that is used for being connected with a local internet, the 3rd connectivity port that is used for being connected with interactive system IS net, the 4th connectivity port that is used for being connected with vehicle body CAR net, be used for netting the 5th connectivity port that is connected with comfortable CONF and being used for netting the 6th connectivity port that is connected with entertainment information INFODIV, to adapt to the electric framework of the used AEE2010 of PSA.
Further, described connectivity port and general connector are complementary, to reduce cost.
By following description also in conjunction with the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used to explain embodiment of the present utility model.
Description of drawings
Fig. 1 is the syndeton schematic diagram of existing network diagnosis interface.
Fig. 2 is structure and the user mode schematic diagram of an embodiment of the utility model vehicle CAN-LIN network diagnosis interface.
Embodiment
With reference now to accompanying drawing, describe embodiment of the present utility model, the similar elements label is represented similar elements in the accompanying drawing.As mentioned above, the utility model provides a kind of vehicle CAN-LIN network diagnosis interface, and it can break through the restriction of BSI gateway, and the communication between monitoring BSI and its downstream ECU and each ECU makes things convenient for the analysis of technical staff to vehicle.
Elaborate the technical scheme of the utility model embodiment below in conjunction with accompanying drawing.As shown in Figure 2, present embodiment is an example with the electric framework of the AEE2010 of PSA, and the structure of vehicle CAN of the present utility model-LIN network diagnosis interface is described.Described vehicle CAN-LIN network diagnosis interface comprises and is used for passing through the direct-connected a plurality of connectivity ports of cable with corresponding CAN/LIN network.Concrete, second connectivity port 2 that described connectivity port comprises first connectivity port 1 that is used for being connected with a local internet LIN.1, be used for being connected with another local internet LIN.2, the 3rd connectivity port 3 that is used for being connected, the 4th connectivity port 4 that is used for being connected, be used for netting the 5th connectivity port 5 that is connected with CONF and being used for netting the 6th connectivity port 6 that is connected, to adapt to the electric framework of the used AEE2010 of PSA with INFODIV with the CAR net with the IS net.Preferably, described connectivity port is a general connector, because general connector is convenient to buying, and low price, and then can reduce cost.BSI among Fig. 2 and OBD diagnose interface only for the ease of understanding the difference of the utility model and prior art, do not limit protection range of the present utility model.
When carrying out network diagnosis, the technical staff can insert described vehicle CAN-corresponding connectivity port of LIN network diagnosis interface by demand, and received signal is so that monitor network and send signal so that network diagnosis.
Need to prove that the utility model is applicable to AEE2010, its principle also is applicable to other electric framework of PSA, as AEE2004, AEE2004EV etc.
