[0042] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0043] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0044] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0045] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0046] To facilitate understanding, a specific application scenario is first exemplified below.

[0047] See also Figure 1 , is a schematic diagram of an application scenario provided by an embodiment of the present application. Figure 1 As shown, this application scenario shows a vehicle 100, a CANoe device 200, and an ECU control device 300. Vehicle 100 contains an ECU 101, also known as the vehicle's "driving computer." Its purpose is to control the vehicle's driving state and implement its various functions. Specifically, it utilizes data collection and exchange from various sensors and buses to determine the vehicle's state and the driver's intentions, and to control the vehicle through various actuators, where these actuators can be understood as controlled devices. CANoe device 200 is a device based on the CAN bus development environment, capable of modeling, simulating, testing, and developing CAN communication networks. ECU control device 300 is a program-controlled processing device, which can be a computer, etc. in practical applications. ECU control device 300 is communicatively connected to CANoe device 200, which in turn is communicatively connected to vehicle 100. Specifically, the communication connection between CANoe device 200 and vehicle 100 is a communication connection between CANoe device 200 and ECU 101 within vehicle 100.

[0048] It should be pointed out that Figure 1 This is only an illustrative description of the application scenario involved in the embodiment of the present application and should not be used as a limitation on the scope of protection of this application. For example, the vehicle 100 involved in the above application scenario can be a sports car, a sedan, a van, etc. The embodiment of the present application does not limit the specific form of the vehicle 100. In addition, it is understood that in addition to the vehicle 100 in the application scenario, Figure 1 In addition to the vehicle 100, ECU 101, CANoe device 102 and computer 103 involved, there are other functional units or modules, which will not be described in detail in the embodiments of the present application.

[0049] In the prior art, when an ECU needs to be muted, a worker typically needs to input a large number of relevant service commands via a computer to achieve the ECU muting control. Understandably, in the prior art, when muting an ECU, the worker needs to spend a considerable amount of time inputting the relevant service commands, which makes the entire vehicle functional testing inefficient.

[0050] To address the above issues, the present invention provides an electronic control unit control method. By compiling a mute instruction for silencing the ECU and configuring related mute operations within the ECU control script, personnel can directly mute the ECU, significantly reducing the time required for vehicle functional testing and improving vehicle testing efficiency. This is described in detail below.

[0051] See also Figure 2, is a flow chart of an ECU control method provided in an embodiment of the present application. This method can be applied to Figure 1 The application scenarios shown are as follows: Figure 2 As shown, it mainly includes the following steps.

[0052] Step S201: In response to the ECU mute operation triggered by the staff, a mute instruction is sent to the ECU based on the ECU control script.

[0053] In practice, a worker can trigger an ECU mute operation on a computer. Upon receiving this trigger, the computer sends a mute command to the ECU via the CANoe device. Specifically, an ECU control script can be preconfigured on the computer, and mute commands can be sent to the ECU based on this script. ECU mute operations can include keystrokes, voice commands, and fingerprints defined in the ECU control script. A mute command prohibits the ECU from sending messages to the controlled device.

[0054] For example, "Pressing the S key on the keyboard" is an ECU mute operation configured in the ECU control script. To mute the ECU, the operator presses the S key on the keyboard. Following the instructions written in the ECU control script, the computer sends a mute command to the ECU via the CANoe device, preventing the ECU from sending messages to the devices it controls.

[0055] It's worth noting that the CANoe software interface contains a program input box for compiling CANoe projects. Therefore, when pressing the "S" button, the computer display must not be on the CANoe software interface with the program input box. This prevents the "S" button from compiling the CANoe project instead of disabling the ECU.

[0056] In one possible implementation, the ECU control script described above can be a Communication Access Programming Language (CAPL). CAPL is a CAN bus access programming language, similar to C language, which can be applied to CANoe projects. It is a very mature programming language used in automotive electronics development. In the embodiment of the present application, CAPL is used as the script development language, which is easy to write and is also conducive to loading in the CANoe project.

[0057] Step S202: Receive the mute response information sent by the ECU, which is used to prompt the ECU whether the mute is successful.

[0058] In an embodiment of the present application, the ECU receives a mute instruction, performs mute processing according to the mute instruction, and after the mute processing is completed, determines whether the mute is successfully performed. The ECU sends a mute response message to the computer based on whether the mute is successfully performed. Specifically, the ECU sends the mute response message to the CANoe device, and the CANoe device then sends the received mute response message to the computer. The mute response message is used to indicate whether the ECU has successfully mute.

[0059] Specifically, the mute response information may include a mute success response information and a mute failure response information. The mute success response information indicates that the ECU has successfully muted, while the mute failure response information indicates that the ECU has failed to mute. For example, the mute success response information is 0 or 1, and the mute failure response information is 1 or 0.

[0060] In one possible implementation, if the ECU is successfully disabled and the disable command is executed successfully, the computer will receive a successful disable response from the ECU via the CANoe device and display the corresponding "S" button on the CANoe software interface. CANoe software analysis interfaces, such as the Trace interface, will also indicate that the target ECU has stopped sending messages, and the vehicle's instrument panel fault light will illuminate. If the ECU is not successfully disabled, the ECU will send a failed disable response to the computer via the CANoe device, and the corresponding "S" button will not be displayed on the CANoe software interface.

[0061] In an embodiment of the present application, the staff performs a mute operation on the ECU through the ECU control script. Since there is no need to enter relevant service instructions during the process of performing the mute operation on the ECU, the time consumed in the functional testing of the vehicle can be greatly shortened, thereby improving the functional testing efficiency of the vehicle.

[0062] See also Figure 3 , is a flow chart of another ECU control method provided in an embodiment of the present application. This method can be applied to Figure 1 The application scenarios shown are as follows: Figure 3 As shown, this method Figure 2 The following steps are also included after step S202.

[0063] Step S301: In response to the ECU mute release operation triggered by the staff, a mute release instruction is sent to the ECU based on the ECU control script.

[0064] In actual applications, after the ECU receives the mute instruction and completes the mute, the vehicle needs to be functionally tested. When the functional test is completed, the normal operation of the ECU needs to be restored. At this time, the ECU needs to be unbanned. The staff can trigger the ECU mute release operation in the computer. After the computer receives the ECU mute release operation triggered by the staff, it sends the mute release instruction to the ECU through the CANoe device. Specifically, the ECU control script can be pre-configured in the computer. The computer sends the mute release instruction to the ECU based on the ECU control script. Specifically, the computer sends the mute release instruction to the CANoe device, and the CANoe device then sends the received mute release instruction to the ECU. Among them, the mute release instruction is used to indicate that the ECU is allowed to send messages to the controlled device; the ECU mute release operation can be a button, voice, fingerprint, etc. defined in the ECU control script.

[0065] For example, "pressing the R key on the keyboard" is an ECU mute removal operation configured in the ECU control script. When the ECU needs to be muted, the operator can press the R key on the keyboard. Following the instructions programmed in the ECU control script, the computer sends a mute removal command to the ECU via the CANoe device, restoring the ECU to its working state.

[0066] It is worth noting that, as mentioned above, when pressing the "R" button, the display interface on the computer cannot be the CANoe software interface with a program input box, to prevent the "R" button from being used to compile the CANoe project instead of being used as an ECU disable operation to unlock the ECU.

[0067] Step S302: receiving a muting release response message sent by the ECU, and using the message to indicate whether the ECU has successfully released the muting.

[0068] In an embodiment of the present application, the ECU receives a ban release instruction, performs ban release processing according to the ban release instruction, and after the ban release processing is completed, determines whether the ban is successfully released. The ECU sends a ban release response message to the computer through the CANoe device based on whether it has successfully lifted the ban. The ban release response message is used to prompt the ECU whether the ban is successfully lifted.

[0069] Specifically, the muting release response information may include a muting release success response information and a muting release failure response information. The muting release success response information indicates that the ECU has successfully released the muting; the muting release failure response information indicates that the ECU has failed to release the muting. For example, the muting release success response information displays the corresponding button, while the muting release failure response information does not display the corresponding button.

[0070] In one possible implementation, if the ECU successfully removes the mute, the ECU mute removal command is successfully executed, and the computer receives a mute removal success response message sent by the ECU via the CANoe device, displays the corresponding button "R" on the CANoe software interface, and the vehicle's instrument panel returns to normal. If the ECU fails to remove the mute, the ECU sends a mute removal failure response message to the computer via the CANoe device, and does not display the corresponding button "R" on the CANoe software interface.

[0071] In some possible application scenarios, different ECUs need to be muted during vehicle functional testing. During testing, in order to determine the current ECU, the ID information of the target ECU can be configured in the ECU control script. The details are explained in detail below.

[0072] See also Figure 4 , is a flow chart of another ECU control method provided in an embodiment of the present application. This method can be applied to Figure 1 The application scenarios shown are as follows: Figure 4 As shown, this method Figure 3 As shown, step S401 is added before step S201.

[0073] Step S401: Receive the request ID and response ID of the target ECU input by the staff.

[0074] In actual applications, before the staff triggers the ECU mute operation defined in the control script, they also need to enter the target ECU's request ID and response ID in the ECU control script to achieve more precise control of the target ECU. The request ID is the address used by the target ECU to receive control instructions, and the response ID is the address used by the target ECU to send a response to whether the mute operation is successful.

[0075] In the embodiment of the present application, each ECU has a corresponding request ID and response ID. For example, the correspondence between the ECU and the request ID and response ID is shown in Table 1.

[0076] Table 1:

[0077]

[0078]

[0079] In one possible implementation, when the target ECU is ECU1, according to the ECU mute operation triggered by the staff, the computer can send a mute instruction to the request ID1 through the CANoe device, so that ECU1 performs the mute operation, and then receives the success response information or failure response information sent from the response ID1, so that the staff can know whether the ECU mute instruction is successfully responded to.

[0080] Step S2011, Figure 3 In addition to step S201, the method further includes: in response to the ECU mute operation triggered by the staff, sending a mute instruction to the request ID of the target ECU based on the ECU control script.

[0081] Step S2021, in Figure 3 In addition to step S202, the method further includes: receiving a mute response message sent by the response ID of the target ECU, where the mute response message is used to prompt the ECU whether the mute is successfully performed.

[0082] The specific process of step S2011 and step S2021 is described above and will not be repeated here.

[0083] Step S3011, Figure 3 In addition to step S301, the method further includes: in response to the ECU mute release operation triggered by the staff, sending a mute release instruction to the request ID of the target ECU based on the ECU control script.

[0084] Step S3021, Figure 3 In addition to step S302, the method further includes: receiving a muting release response message sent by the response ID of the target ECU, where the muting release response message is used to indicate whether the ECU has successfully released the muting.

[0085] For example, referring to Table 1, when the target ECU1 is muted, according to the ECU muting operation triggered by the staff, the computer can send a muting removal instruction to the request ID1 through the CANoe device, so that the target ECU1 executes the muting removal operation, and then receives the success response information or failure response information sent from the response ID1, so that the staff can know whether the ECU muting removal instruction is successfully responded to.

[0086] See also Figure 5 , is a flow chart of another ECU control method provided in an embodiment of the present application. This method can be applied to Figure 1 The application scenarios shown are as follows: Figure 5 As shown, this method Figure 4 As shown, step S501 is added before step S2011.

[0087] Step S501: In response to a mute button setting instruction input by a staff member, a mute button is set.

[0088] In an embodiment of the present application, a staff member can set a mute operation in the ECU control script to be a key pressed on a computer keyboard. For example, the mute operation can be defined as letter keys such as "A," "B," and "C," or as numeric keys or other character keys on the keyboard. This application does not impose specific limitations on this. When the mute operation is defined as pressing a defined key on the keyboard, there is no need to add a separate trigger device to the device, reducing the complexity of the device while ensuring performance.

[0089] In addition, if Figure 5 As shown, this method Figure 4 As shown, step S502 is added before step S3011.

[0090] Step S502: In response to the muting release button setting instruction input by the staff, a muting release button is set.

[0091] In an embodiment of the present application, a staff member can set the ECU control script to press a key on the computer keyboard as the muting release operation. For example, the keyboard letter keys "A," "B," "C," etc. can be defined, or numeric keys or other character keys can be defined, which is not specifically limited in this application. When the muting release operation is defined as pressing a defined key on the keyboard, there is no need to add a separate trigger device to the device, which reduces the complexity of the device while ensuring performance.

[0092] Step S20111, in Figure 4 On the basis of step S2011 shown, it also includes: in response to the ECU mute operation triggered by the staff through the mute button, sending a mute instruction to the request ID of the target ECU based on the ECU control script.

[0093] Step S30111, in Figure 4 On the basis of step S3011 shown, it also includes: in response to the ECU mute release operation triggered by the staff through the mute release button, sending a mute release instruction to the request ID of the target ECU based on the ECU control script.

[0094] For ease of understanding, the control method of the electronic control unit provided in the embodiment of the present application is described in detail below in conjunction with a specific implementation method.

[0095] See also Figure 6 , a flow chart of another ECU control method provided in an embodiment of the present application. This method can be applied to Figure 1 The application scenarios shown are as follows: Figure 6As shown, the specific steps include the following steps.

[0096] Step S601: The vehicle is connected to the CANoe device.

[0097] Step S602: Open the CANoe project and load the CAPL script.

[0098] Step S603: Set the request ID and response ID of the ECU to be muted in the CAPL script.

[0099] Step S604: Setting a customized mute button and unmute button in the CAPL script.

[0100] Step S605: Compile and save the CAPL script.

[0101] Step S606: Run the CANoe project and press the custom mute button in the CANoe software interface.

[0102] Step S607: The muting is successful, the customized button responds successfully, and the CANoe software interface will display the corresponding button.

[0103] Step S608: The ECU is prohibited from sending messages to the controlled device, and the vehicle instrument fault light is turned on.

[0104] Step S609: Run the CANoe project and press the custom mute release button in the CANoe software interface.

[0105] Step S610: The ban is successfully lifted, the customized button responds successfully, and the CANoe software interface will display the corresponding button.

[0106] Step S611: Exit the mute mode and the instrument returns to normal.
