First describe according to the gateway test method of the CAN network of the embodiment of the present invention below in conjunction with accompanying drawing.
At least comprise a CAN bus and the 2nd CAN bus according to the CAN network of the gateway test method of the CAN network of the embodiment of the present invention, and a CAN bus and the 2nd CAN bus communicate by gateway.As shown in Figure 1, the one CAN bus CAN1 is connected with gateway respectively with the 2nd CAN bus CAN2, take the bus that is positioned at gateway top as a CAN bus CAN1, what need understanding is, in actual vehicle, a CAN bus CAN1 and the 2nd CAN bus CAN2 have different communication standards, and the effect of gateway is changed communication protocol and the communication information is forwarded, the specific implementation of gateway is prior art, does not repeat herein.In addition, as shown in Figure 1, a part of controller of vehicle hangs on a CAN bus CAN1, another part controller hangs on the 2nd CAN bus CAN2, as engine management system EMS, anti-lock braking system ABS and electrical control automatic manual transmission case AMT etc. are articulated on a CAN bus CAN1, in addition as vehicular meter IC and battery management system BCM etc. are articulated on the 2nd CAN bus CAN2.
As shown in Figure 2, according to the gateway test method of the CAN network of the embodiment of the present invention, comprise the following steps:
Step S201, selects test packet, and from test packet, selects first signal as test signal.Particularly, test packet is from the shortest message of transmission cycle in the list of gateway forwards signal.As engine management system EMS is sent to the message of IC.Preferably, test packet is the message of cycle minimum in the list of gateway forwards signal.First signal is sinusoidal signal, be that test signal is sinusoidal signal, why select sinusoidal signal as test signal, be because sinogram as time become feature comparatively obvious, once there is frame losing or the wrong phenomenon that sends in gateway, can tell significantly the difference with original signal.
It should be noted that, select the shortest message of transmission cycle (cycle) to test, can effectively judge gate performance, if this is because gateway is no problem to the forwarding of the shortest message of transmission cycle, can think that the message that the gateway forwards cycle relatively grows does not also have problems.
Step S202, is sent to test signal in the one CAN bus.Send to a CAN bus by the sinusoidal signal of cycle minimum in message.It should be noted that, it is only exemplary that test signal is sent in a CAN bus, in other examples of the present invention, also test signal can be sent in the 2nd CAN bus.
Step S203, gateway is forwarded to test signal in the 2nd CAN bus.In test signal being sent in a CAN bus, gateway communicates protocol conversion according to its function to this test signal and forwards it in the 2nd CAN bus, and gateway can be broadcast in the 2nd CAN bus with the form of broadcast.
Step S204, gathers the reception signal in the transmitted signal in a CAN bus and the 2nd CAN bus.Wherein, transmitted signal refers to above-mentioned test signal, receives signal and refer to be forwarded to the signal in the 2nd CAN bus after gateway processes.In an example of the present invention, the collection of the reception signal in the transmitted signal in the one CAN bus and the 2nd CAN bus is synchronously carried out, like this, in follow-up processing procedure, owing to being synchronous acquisition, therefore can, according to the time difference of transmitted signal and reception signal, judge the real-time of gateway to signal processing.In this example, can the reception signal in the transmitted signal in the one CAN bus and the 2nd CAN bus be gathered by signal collecting device, like this, just can record gateway forwards front and back signal simultaneously.
Step S205, analyzes transmitted signal and receives signal to determine according to analysis result whether gateway meets preassigned.
Particularly, as shown in Figure 3, analyze transmitted signal and receive signal and further comprise to determine the step whether gateway meets preassigned according to analysis result:
Step S301, relatively transmitted signal and reception signal.Whether identically judge transmitted signal and receive signal.
Step S302, if transmitted signal is identical with reception signal, judges that gateway meets preassigned, and gateway can meet the forwarding requirement of the signal that the different CAN buses of CAN network are sent.
As shown in Figure 4, analyze transmitted signal and receive signal and also comprise to determine the step whether gateway meets preassigned according to analysis result:
Step S401, relatively transmitted signal and reception signal.Whether identically judge transmitted signal and receive signal.
Step S402, if transmitted signal is different with reception signal, further judges gateway forwards mistake or frame losing according to transmitted signal and reception signal.
Further, as shown in Figure 5, in step S402 according to transmitted signal and receive signal judge that the step of gateway forwards mistake or frame losing further comprises:
Step S501, carries out image conversion to transmitted signal and reception signal respectively by image processing software.Particularly, can carry out image conversion to transmitted signal and reception signal respectively by more existing image processing softwares, to can demonstrate intuitively the image of transmitted signal and reception signal.
Step S502, analyzes image transformation result, to be judged to be gateway forwards mistake or gateway forwards frame losing.For example: can be analyzed the image difference that demonstrates two signals to the image of two signals by more existing image analysis software, and be judged to be gateway forwards mistake or gateway forwards frame losing according to difference.Particularly, preassigned is the standard of predefined gateway test, can judge that according to it whether intended gateway is by test.For example, according to analysis result, judge whether the real-time of gateway forwards is accepted, and the frame losing of gateway or whether in the reasonable scope forward mistake, like this, just can show whether gateway meets preassigned, and whether gateway is qualified.
In above-mentioned example, because the signal that gateway forwards is different, according to the list of tested gateway forwards signal, choosing the wherein message of cycle minimum is test packet.Utilize software simulation real node to send a test signal for real-time change sinusoidally, at present some CAN testing softwares all support simulation to send the signal of variation sinusoidally substantially in addition, make the versatility of method of the embodiment of the present invention stronger.Test signal simulated and is sent in a CAN bus, gateway is forwarded in the 2nd CAN bus, by signal collecting device, the signal in two network segments is gathered simultaneously, gateway forwards front and back signal pattern is just simultaneously by bus test software records like this, again by relational graph process software, just can see intuitively the image of two signals on time shaft, analyze gateway whether the processing of signal is met to relevant criterion, thereby judge that whether intended gateway is by test.
According to above-mentioned example, only need to test a concrete sinusoidal signal, needn't write complicated test case, the result iamge description of test, and it forwards the signal pattern of front and back by contrast, just can reflect intuitively forwarding mistake or the frame loss condition of gateway, judge that whether gateway is by test.
Fig. 6 is the test result schematic diagram of the gateway test method of CAN network according to an embodiment of the invention.Can identify gateway by contrast images and in the process of forward signal, whether occur " frame losing " or " mistake forwarding " phenomenon.Particularly, the situation that frame losing occurs: compared with test signal, the signal outstanding feature of frame losing is that the image of signal seems " having been pruned ", and a certain section of image is the line segment between bright spot.When frame losing, due to part signal disappearance, image just becomes the line of not frame losing part; Mistake forwards the situation occurring: the image after forwarding is different from original signal image signal value within certain a period of time.
According to the gateway test method of the CAN network of the embodiment of the present invention, only need to test a test signal actual in the CAN network of vehicle, just can test out real-time and the accuracy of the signal transfer capability of gateway, have that testing cost is low, human cost is low and the advantage such as simple.In addition, the test signal of the method based on reality tested gateway, and therefore, test result can be reacted gate performance objectively, has advantages of that measuring accuracy is high.

Signal picker 750 gathers for the reception signal in the transmitted signal in a CAN bus 710 and the 2nd CAN bus 720.Particularly, signal picker 750 gathers the reception signal in the transmitted signal in a CAN bus 710 and the 2nd CAN bus 720, and like this, signal picker 750 just can be recorded gateway forwards front and back signal simultaneously.
Controller 760, for to transmitted signal with receive signal and analyze, and determines according to analysis result whether gateway 730 meets reservation standard.Particularly, controller 760 is transmitted signal and reception signal first relatively, if transmitted signal is identical with reception signal, judges that gateway 730 meets preassigned.If transmitted signal is different with reception signal, further judge that according to transmitted signal and reception signal gateway 730 forwards mistake or frame losing.Particularly, respectively transmitted signal and reception signal are carried out to image conversion by associated picture process software, to can demonstrate intuitively the image of transmitted signal and reception signal, by relevant image analysis software, two signals are analyzed again, and demonstrate the image difference of two signals, then be judged to be gateway 730 according to difference and forward mistake or gateway forwards frame losing.Wherein, preassigned is the standard of predefined gateway test, can judge that according to it whether gateway 730 is by test.
As a concrete example, transmission, the reception etc. of test signal also tested gateway by the mode of emulation.Particularly, utilize CANOE software etc., the test signal simulating is changed sinusoidally, then this signal (transmitted signal) is sent, after gateway forwards, then the signal (reception signal) after forwarding is gathered, signal pattern before and after gateway forwards is presented in same width figure, just can see intuitively the difference of two figure, analyze gateway whether the processing of signal is met to relevant criterion, thereby judge that whether intended gateway is by test.Using vehicle speed signal as test signal, processing procedure is as follows below:
1,, after system powers on, run under normal condition;
2, utilize the signal imitation function of bus test equipment 740 or CANOE software that the physical values of vehicle speed signal is designed to sinusoidal variable, and continue to send a period of time;
3, by " figure Graphics " function in CANOE software, whole process is showed by the mode of chart;
