[0047] In order to make the above and other features and advantages of the present application more clear, the present application is further described below with reference to the accompanying drawings. It should be understood that the specific embodiments given herein are for the purpose of explaining to those skilled in the art and are only exemplary and not restrictive.

[0048] In the following description, many specific details are set forth to provide a thorough understanding of the present application. However, it will be apparent to those skilled in the art that it is not necessary to adopt the specific details to practice the present application. In other cases, well-known steps or operations are not described in detail to avoid obscuring the present application.

[0049] The start-stop function test method based on Autosar provided in the embodiment of the present application can be performed by the start-stop function test device based on Autosar provided in the embodiment of the present application, and the device can be configured in a vehicle or electronic equipment.

[0050] This application provides a start-stop function test method based on Autosar, refer to the attached Figure 1 As shown, it is a flow chart of a start-stop function test method based on Autosar provided in an embodiment of the present application, and the method includes steps 110-140.

[0051] Step 110 : When the first wakeup source of the vehicle is in a start / stop state, the second wakeup source is started in a different network management state.

[0052] The wakeup source in this application refers to an event or condition that causes a process to transition from one functional state to another. For example, when a process is waiting for an event to occur, it enters a certain state. Once the event occurs, the process is awakened and transitions to another state, the ready state, to wait for further execution. The wakeup source in this application can be multiple, including at least a first wakeup source and a second wakeup source.

[0053] In an exemplary embodiment, the first wakeup source includes any one of the following: READY (vehicle start), AC (alternating current charging), and DC (direct current charging).

[0054] In an exemplary embodiment, the second wake-up source may also include any one of the following: READY (vehicle start), AC (alternating current charging), and DC (direct current charging).

[0055] It is understandable that when performing the test, the first wakeup source and the second wakeup source are different wakeup sources.

[0056] For example, the start-stop operating conditions described in this application may include: the operating conditions corresponding to when the Ready ON and Ready OFF functions are triggered during vehicle startup, the operating conditions corresponding to AC charging start (starting the charging function when the AC gun is connected), the operating conditions corresponding to AC charging stop (stopping the charging function when the AC gun is unplugged), the operating conditions corresponding to DC charging start (starting the DC charging function when the DC gun is connected), and the operating conditions corresponding to DC charging stop (stopping the charging function when the DC gun is unplugged), etc. The above are only examples, and this application is not limited to this, and may also include other start-stop functions of the vehicle.

[0057] Step 120 : Acquire the network management state parameter of the vehicle after the second wake-up source is activated as the first reference network management state parameter.

[0058] Step 130: Stop the second wakeup source in different network management states and obtain a second reference network management state parameter.

[0059] In an exemplary embodiment, different network management states include the network management state of at least one of the following controllers: a vehicle control unit (VCU), a battery management controller (BMS), an on-board charger controller (OBC), and a motor controller (DU).

[0060] In an exemplary embodiment, referring to the attached Figure 2 As shown, the network management status of each controller includes at least: bus sleep state parameter (BS for short), repeated message state parameter (RM for short), normal operation state (NO for short), ready to sleep state (RS for short), and pre-sleep state (PBS for short).

[0061] For example, the test method of the present application tests whether the network management states of the two wakeup source combinations are abnormal by injecting the start / stop signal of another wakeup source in different network management states when one wakeup source is in the start / stop state.

[0062] For example, refer again to Figure 2 The following is a timing diagram of the network status of each controller in the 1st state (i.e. 1stReady state) of this application. Figure 2 The working sequence diagram of the network management status of the four controllers VCU, BMS, OBC and DU is specifically shown, that is, the different network management states under the 1st start-stop condition.

[0063] At this time, the present application can inject another start-stop function signal in different network management states (ie, enter the 2nd state) based on the start-stop function of each functional state being in the 1st state. Figure 3The AC start / stop function signal is injected at the beginning of the 1st RM state to enter the 2nd state. The timing for canceling the injection of the AC start / stop function signal is before the end of the RM state, at the end of the RM state, in the NO state, at the end of the 1st state, or 500ms after the end of the 1st state. Figure 4 In the 1st NO state, the AC start / stop function signal is injected to enter the 2nd state. The timing to cancel the injection of the AC start / stop function signal is 100ms after entering the 2nd state, at the end of the 1st state, and 500ms after the end of the 1st state. Figure 5 The AC start / stop function signal is injected at the beginning of the 1st RS state to enter the 2nd state. The timing for canceling the injection of the AC start / stop function signal is 1 second after the beginning of the RS state, 3.5 seconds after the beginning of the RS state, or 5 seconds after the beginning of the RS state. Figure 6 The AC start / stop function signal is injected at the beginning of the 1st PBS state to enter the 2nd state. The timing of canceling the injection of the AC start / stop function signal is 1 second after the beginning of the PBS state or 3 seconds after the beginning of the PBS state.

[0064] In an exemplary embodiment, as shown in Table 1, the present application will Figure 3 The AC signal injection point in is set to A. According to the different cancellation injection points, corresponding situations ①, ②, ③, ④, and ⑤ are generated. Figure 4 The AC signal injection point in is set to B. Depending on the different cancellation points, corresponding situations ①, ②, and ③ are generated. Figure 5 The AC signal injection point is set to C. Depending on the cancellation of the injection point, corresponding situations ①, ②, and ③ are generated. Figure 6 Note that the AC input point is set to D. Depending on the different cancellation points, corresponding situations ① and ② are generated. Therefore, in this embodiment, injecting AC start / stop function signals under different network management states of 1stREADY generates at least 5+3+3+2=13 test situations. Other start / stop function combination test situations can be obtained using the same method and are not listed here.

[0065]

[0066] Table 1 Different network management states of 1stREADY, injected into 2ndAC

[0067] In an exemplary embodiment, referring to the attached Figure 2-6As shown, starting the second wakeup source in different network management states includes: taking the start timing of the first controller entering a network management state as the timing for starting the second wakeup source in the current network management state; and taking the end timing of the first controller ending a network management state as the timing for stopping the second wakeup source in the current network management state. Figure 5 In the scheme of injecting AC into RS state, since VCU is the first controller to enter RS ​​state, the timing of VCU entering RS state is used as the timing of injecting AC; Figure 6 In the PBS state, when injecting AC, since the VCU is the first controller to enter the PBS state, the timing of injecting AC is when the VCU starts entering the PBS state. The timing of canceling the injection (i.e., stopping AC) is when the first controller to exit the corresponding state is used as the cancellation timing.

[0068] In an exemplary embodiment, the first reference network management state parameter includes: the time when each controller starts sending messages and the state of the sent messages, the operating current, and the time when each controller wakes up. The second reference network management state parameter includes: the time when each controller stops sending messages, the operating current, and the time when each controller sleeps.

[0069] Step 140: Obtain a test result under a combined working condition of the first wakeup source and the second wakeup source based on the first reference network management state parameter and the second reference network management state parameter.

[0070] Based on the first reference network management state parameter and the second reference network management state parameter, a test result under the combined working condition of the first wake-up source and the second wake-up source is obtained, wherein the first reference network management state parameter and the second reference network management state parameter can be compared with their respective evaluation criteria to determine whether the test passes.

[0071] For example, Figure 7 and Figure 8 The test results of A① in Table 1 are shown. Figure 7 This is the A①CAN message sending and receiving test result. You need to pay attention to whether the timing of starting and stopping sending messages by VCU, BMS, OBC or DU is correct. Figure 8 If it is the result of A① sleep stop test, you need to pay attention to whether the timing of VCU, BMS, OBC or DU wake-up and sleep is correct. Specifically, Figure 7The two boxes in the figure respectively indicate when each controller starts and stops sending messages. When the 1st state is activated, each controller starts sending messages. Even after the AC start-stop function is injected and the 2nd state is entered, the controller's message sending is still not affected. When both the 1st and 2nd states are deactivated, each controller stops sending messages. This is used to determine whether the functional test results for the two wake-up source combinations are normal. Figure 8 The two boxes in the figure respectively indicate the controller's wakeup and sleep states. When the 1st state is activated, each controller sends messages, and the operating current is greater than 0. After the AC start-stop function is applied and the 2nd state is entered, the controller's message transmission is still not affected, and the operating current remains greater than 0. When both the 1st and 2nd states are deactivated, each controller stops sending messages, and the operating current approaches 0. Based on this, the function test result is considered normal. A④ injects AC at the beginning of the 1st RM state and removes the AC start-stop function at the end of the 1st RM state.

[0072] For example, Figure 9 and Figure 10 This is the test result of A④. Figure 9 This is the test result of A④CAN signal sending and receiving messages. It is necessary to pay attention to whether the timing of starting and stopping sending messages by VCU, BMS, OBC or DU is correct. Figure 10 The result of the A④ sleep stop test is correct. You need to pay attention to whether the VCU, BMS, OBC, or DU wake-up and sleep timings are correct. Figure 9 The two boxes in the figure respectively indicate when each controller starts and stops sending messages. When the 1st state is enabled, each controller starts sending messages. Even after the AC start-stop function is applied and the system enters the 2nd state, this does not affect the controller's ability to send messages. When both the 1st and 2nd states are disabled, each controller stops sending messages, and this indicates that the function test result is normal. Figure 10 The two boxes in the figure respectively indicate the wakeup and sleep states of each controller. When the 1st state is activated, each controller sends messages and the operating current is greater than 0. After the AC start-stop function is injected and the 2nd state is entered, the controller still sends messages and the operating current remains greater than 0. When both the 1st and 2nd states are deactivated, each controller stops sending messages and the operating current approaches 0. Based on this, the function test result is determined to be normal.

[0073] In the present application, when the first wake-up source of the vehicle is in the start / stop condition, the second wake-up source is started in different network management states; the network management state parameters of the vehicle after starting the second wake-up source can be obtained and used as the first reference network management state parameters; then, the second wake-up source is stopped in a different network management state to obtain the second reference network management state parameters; finally, based on the first reference network management state parameters and the second reference network management state parameters, the test results under the combined working condition of the first wake-up source and the second wake-up source can be obtained. In the present application, by obtaining the first reference network management state parameters by starting the second wake-up source in different network management states and the second reference network management state parameters by stopping the second wake-up source in different network management states, it is possible to test whether the network management states of different controllers under the combined working condition are normal, and it is also possible to test whether the start-stop functions under the network management states of multiple controllers are working normally. This solves the technical problem that the prior art only discloses research on testing changes in the network management state of a single controller, but lacks testing changes in the network management state of multiple controllers under the joint debugging condition.

[0074] Refer to the attached Figure 11 As shown, according to an embodiment of the present application, a start-stop function test device based on Autosar is provided, including: a wake-up start module 1101, a first acquisition module 1102, a second acquisition module 1103, and a third acquisition module 1104.
