[0002] With the continuous development of the automobile industry, users have higher and higher demands for the intelligence of automobiles. Therefore, the functions of vehicles are constantly increasing, and the number of engine control units (ECUs) on the vehicle is also increasing.

[0003] In the related art, the communication between ECUs and the flashing of ECUs are realized through the Controller Area Network (CAN). As the number of ECUs increases, the load rate of the CAN network gradually increases, and relying solely on CAN network communication has gradually failed to meet the needs of users. Although the variable rate CAN network (CAN with Flexible Data-Rate, CANFD) is gradually replacing the traditional CAN network, the flashing of ECUs is still realized through the CAN network in the related art.

[0004] As the application of Over-the-Air Technology (OTA) in smart cars increases, using only the CAN network to flash the ECU may cause the CAN network to be overloaded and unable to meet the user's intelligent needs.

[0005] It should be pointed out that the information disclosed in the background technology section of this application is only intended to deepen the understanding of the general background technology of this application, and should not be regarded as an admission or suggestion in any form that the information constitutes prior art already known to those skilled in the art. Summary of the invention

[0006] In view of this, the present application provides an ECU flashing method to help solve the problem in the prior art that only using the CAN network to flash the ECU may cause the CAN network to be overloaded and unable to meet the user's intelligent needs.

[0007] In a first aspect, an embodiment of the present application provides an ECU flashing method, the method comprising:

[0011] In the embodiment of the present application, the flashing of the ECU is achieved through CANFD, which can reduce the load of the CAN network and meet the user's demand for intelligence. The method provided in the embodiment of the present application can use domestic flashing equipment, reduce equipment limitations, improve the flashing efficiency of the ECU, and save costs.

[0013] Flashing the ECU to be flashed according to the ECU flashing platform and the address information of the ECU to be flashed includes: controlling the flashing device to flash the ECU to be flashed according to the ECU flashing platform and the address information of the ECU to be flashed.

[0014] In the embodiment of the present application, the address information of the ECU to be flashed is obtained through the flashing device, and the flashing device is controlled to flash the ECU to be flashed. It can be understood that the host computer and the ECU cannot be directly connected through the wiring harness, and the ECU needs to be flashed indirectly through the flashing device. The method provided in the embodiment of the present application can be applied to a variety of devices, expanding the scope of application of the ECU flashing method.

[0015] In a possible implementation, before generating the ECU flashing platform according to the security algorithm and the flashing process, the method further includes:

[0016] A security algorithm is generated through a security algorithm generation program according to the encryption algorithm of the ECU to be flashed, and the security algorithm is used to decrypt the ECU to be flashed.

[0017] In the embodiment of the present application, because the ECU has its own encryption algorithm, the ECU to be flashed needs to be decrypted before the ECU can be flashed. In the present application, the ECU flashing device needs to generate a security algorithm through a security algorithm generation program, and generate a security algorithm according to the encryption algorithm of the ECU to be flashed, and the security algorithm can decrypt the ECU to be flashed.

[0019] A security algorithm is generated through a security algorithm generation program according to the encryption algorithm of the ECU to be flashed and the underlying logic of the flashing device. The underlying logic of the flashing device is used to control the flashing device.

[0020] In the embodiment of the present application, when the ECU to be flashed is flashed by the flashing device, the ECU flashing device needs to generate the security algorithm according to the encryption algorithm of the ECU to be flashed and the underlying logic of the flashing device when generating the security algorithm, wherein the underlying logic of the flashing device is used to control the flashing device. It is understandable that when the flashing device is needed, the flashing device needs to be controlled, so the underlying logic of the flashing device needs to be added to the security algorithm, so as to better control the flashing device, and then realize the flashing of the ECU to be flashed.

[0021] In a possible implementation, after generating the ECU flashing platform, the method further includes:

[0022] A test procedure is used to test whether the ECU flashing platform can successfully complete the flashing.

[0026] If the first verification program verifies that the ECU flashing platform can successfully complete the flashing, then the second verification program is used to verify whether the ECU flashing platform can successfully complete the flashing.

[0027] In the embodiment of the present application, two inspection programs are used to respectively inspect whether the ECU flashing platform can successfully complete the flashing. It is understandable that the inspection results of the two inspection programs can be mutually verified, thereby ensuring the reliability of the inspection results and further ensuring the success rate of the flashing.

[0029] Flashing the ECU to be flashed multiple times to determine whether the ECU to be flashed is successfully flashed.

[0030] In the embodiment of the present application, after flashing the ECU to be flashed, the ECU is flashed multiple times. It can be understood that the result of a flashing may be accidental, and multiple flashing can improve the success rate of ECU flashing.

[0032] The address information acquisition module is used to obtain the address information of the ECU to be flashed through the CANFD interface;

[0049] 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.

[0050] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0051] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" 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 other meanings.

[0052] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0053] With the continuous development of the automobile industry, users have higher and higher demands for the intelligence of automobiles. Therefore, the functions of vehicles are constantly increasing, and the number of engine control units (ECUs) on the vehicle is also increasing.

[0054] In the related art, the communication between ECUs and the flashing of ECUs are realized through the Controller Area Network (CAN). As the number of ECUs increases, the load rate of the CAN network gradually increases, and relying solely on CAN network communication has gradually failed to meet the needs of users. Although the variable rate CAN network (CAN with Flexible Data-Rate, CANFD) is gradually replacing the traditional CAN network, the flashing of ECUs is still realized through the CAN network in the related art.

[0055] As the application of Over-the-Air Technology (OTA) in smart cars increases, using only the CAN network to flash the ECU may cause the CAN network to be overloaded and unable to meet the user's intelligent needs.

[0056] In view of the above problems, the embodiment of the present application provides an ECU flashing method, which implements the flashing of the ECU through CANFD, can reduce the load of the CAN network, meet the user's demand for intelligence, and the method provided by the embodiment of the present application can use domestic flashing equipment, reduce equipment limitations, improve the flashing efficiency of the ECU, and save costs. The following is a detailed description in conjunction with the accompanying drawings and specific embodiments.

[0057] See also Figure 1 , is a flow chart of an ECU flashing method provided in an embodiment of the present application. Figure 1 As shown, it mainly includes the following steps.

[0058] Step S101: Acquire the address information of the ECU to be flashed through the CANFD interface.

[0059] Specifically, the ECU flashing device obtains the address information of the ECU to be flashed through the CANFD interface. In a possible implementation, the upper computer software is configured according to the corresponding specifications of the ECU to be flashed, specifically configuring the ECU channel, the ECU frame type (CANFD), the physical address, the function address, and the response address. Because each ECU has a corresponding specification, the ECU flashing device needs to determine the address information of the ECU through the corresponding specification of the ECU when obtaining the address information of the ECU.

[0060] In practical applications, the host computer cannot usually be directly connected to the ECU. Therefore, the information exchange between the host computer and the ECU needs to be completed through the flashing device. Therefore, in a possible implementation, the host computer controls the flashing device to obtain the address information of the ECU to be flashed through the CANFD interface. Among them, the host computer is electrically connected to the flashing device, and the flashing device is electrically connected to the ECU to be flashed through a wiring harness. In a possible implementation, the host computer is a computer, and the flashing device is a Zhou Ligong device (ZLG). Of course, those skilled in the art can set the host computer and the flashing device to other devices according to actual needs, and the embodiment of the present application does not make specific restrictions on this. In a possible implementation, the host computer is connected to the flashing device through a USB cable, and the flashing device is connected to the ECU through a wiring harness UD8. Of course, those skilled in the art can set the connection mode between the host computer and the flashing device and the connection mode between the flashing device and the ECU to other connection modes according to actual needs, and the embodiment of the present application does not make specific restrictions on this.

[0061] For example, see Figure 2 , is a connection diagram of a flash writing device provided in an embodiment of the present application. Figure 2 As shown, the host computer and the ZLG device are connected via USB, the ZLG device and the ECU are connected via the wiring harness UD8, and the CAN_H and CAN_L pins of UD8 are respectively connected to the CAN1 channel (CAN_H and CAN_L) of the ZLG device.

[0062] Step S102: Generate an ECU flashing platform according to the security algorithm and flashing process.

[0063] Specifically, the ECU flashing device generates an ECU flashing platform according to the security algorithm and the flashing process. Among them, the security algorithm is used to decrypt the ECU to be flashed, so that the ECU to be flashed can be edited, and the flashing process is used to flash the ECU to be flashed. It can be understood that generating an ECU flashing platform is more convenient for flashing the ECU in the future. It only needs to successfully connect the ECU to be flashed with the host computer to realize the flashing of the ECU to be flashed through the ECU flashing platform on the host computer.

[0064] In a possible implementation, the flashing process can be input by the user through the host computer. Specifically, the user generates a flashing process framework according to the OTA specification and the CANFD flashing specification, and inputs the flashing process framework into the host computer, so that the host computer can flash through the process.

[0065] In one possible implementation, before generating an ECU flashing platform, it is necessary to generate a program through a security algorithm, and generate a security algorithm according to the encryption algorithm of the ECU to be flashed. The security algorithm is used to decrypt the ECU to be flashed, so that the ECU to be flashed can be edited. Because the ECU has its own encryption algorithm, the ECU to be flashed needs to be decrypted before it can be flashed or edited. In this application, the ECU flashing device needs to generate a program through a security algorithm, and generate a security algorithm according to the encryption algorithm of the ECU to be flashed. The security algorithm can decrypt the ECU to be flashed.

[0066] Specifically, the user runs the security algorithm generation program (sa-demo project) through the software in the host computer, and inputs the encryption algorithm of the ECU to be flashed, thereby generating a security algorithm.

[0067] In a possible implementation, a flashing device is also included between the host computer and the ECU. At this time, when generating a security algorithm, the underlying logic of the flashing device needs to be added to the security algorithm generation program, wherein the underlying logic of the flashing device is used to control the corresponding flashing device. It can be understood that adding the underlying logic of the flashing device to the security algorithm generation program can ensure that the ECU flashing device can better control the flashing device, thereby flashing the ECU to be flashed.

[0068] It can be understood that by taking the code logic of Zhou Ligong's equipment as the theoretical basis, developing a security algorithm program, and calling the driving code parameters of Zhou Ligong's equipment to realize the generation of the security algorithm, the ECU flashing device can better control the flashing device to flash the ECU to be flashed.

[0069] See also Figure 3 , is a schematic diagram of the structure of an ECU flashing platform provided in an embodiment of the present application. Figure 3 As shown, the ECU flashing platform that the user can see through the host computer includes the flashing process 301 and some editing options for the flashing process. The user can flash the ECU through the ECU flashing platform, that is, the next time the user flashes the ECU, he only needs to make some modifications to the ECU flashing platform without rewriting the algorithm, which can greatly save the user's time and improve work efficiency.

[0070] like Figure 3 As shown, the flashing process 301 includes service, data, address, suppression response and delay, wherein service is the name of the operation that the user wants to perform on the EUC to be flashed, data is the data number corresponding to the corresponding service in the ECU specification, address is the address information of the ECU to be flashed, suppression response is whether the service needs to suppress the response, and delay is whether the corresponding service needs to be delayed. The user can set the options corresponding to each service according to actual needs, so that the ECU to be flashed can be flashed according to the user's wishes.

[0071] Step S103: flashing the ECU to be flashed according to the ECU flashing platform and the address information of the ECU to be flashed.

[0072] Specifically, after the ECU flashing device generates the ECU flashing platform, the address information of the ECU to be flashed is input into the ECU flashing platform, and the ECU to be flashed is flashed.

[0073] In a possible implementation, there is a flashing device between the host computer and the ECU, so the host computer cannot flash the ECU directly, and needs to flash the ECU through the flashing device, that is to say. The host computer controls the flashing device to flash the ECU to be flashed according to the ECU flashing platform and the address information of the ECU to be flashed. The method provided in the embodiment of the present application can be applied to a variety of devices, expanding the scope of application of the ECU flashing method.

[0074] In a possible implementation, after generating the ECU flashing platform, the host computer also needs to verify whether the ECU flashing platform can successfully complete the flashing through a verification program. Among them, the verification program can be a program generated by the user through the verification software. Specifically, the user inputs the file containing the ECU flashing platform into the verification software on the host computer, and determines whether the ECU flashing platform can successfully complete the flashing through the verification software. It can be understood that the reliability of the ECU flashing platform can be guaranteed through the verification process, thereby ensuring the success of the flashing.

[0075] See also Figure 4 , is a schematic diagram of a structure in which an ECU flashing platform provided in an embodiment of the present application is successfully flashed. Figure 4 As shown, the flashing result display area 401 displays "Flashing succeeded 1 time, failed 0 times", that is, if the flashing is performed once and the flashing is successful once, then the ECU flashing platform can be flashed successfully. On the contrary, if the flashing result display area 401 displays "Flashing succeeded 0 times, failed 1 time", it means that the flashing is performed once and the flashing fails, then the ECU flashing platform cannot be flashed successfully.

[0076] In a possible implementation, two verification programs are used to verify whether the ECU writing platform can successfully complete the flashing. Specifically, the first verification program is used to verify whether the ECU flashing platform can successfully complete the flashing; if the first verification program verifies that the ECU flashing platform can successfully complete the flashing, the second verification program is used to verify whether the ECU flashing platform can successfully complete the flashing. In a possible implementation, the first verification program is the first verification software, the second verification program is the second verification software, and the first verification program and the second verification program can be domestic verification software and foreign verification software, respectively. The verification results of the two software are verified against each other to obtain more accurate verification results, thereby ensuring the reliability of the verification results and further ensuring the success rate of the flashing.

[0077] In a possible implementation, after the ECU flashing device finishes flashing the ECU to be flashed, it flashes the ECU to be flashed multiple times to determine whether the flashing of the ECU to be flashed is successful. The ECU flashing device can flash the ECU to be flashed 10 times, 100 times, or even 1000 times, and determine whether the ECU can pass the stress test based on the success rate of multiple flashing.

[0078] See also Figure 5 , is a schematic diagram of a structure of an ECU flashing platform stress test provided in an embodiment of the present application. Figure 5 As shown, the flashing result display area 401 displays "10 flashing successes, 0 failures", that is, the ECU flashing device flashes the ECU to be flashed 10 times, and all 10 flashings are successful. At this time, the ECU can continue to be flashed 100 times or more, so as to perform a higher level of stress test on the ECU. Of course, if the flashing result display area 401 displays "0 flashing successes, 10 failures", it means that the ECU flashing has failed.

[0079] In one possible implementation, a success rate threshold is pre-set. If the flashing success rate of the ECU to be flashed is greater than or equal to the preset success rate threshold, the flashing of the ECU to be flashed is successful; if the flashing success rate of the ECU to be flashed is less than the preset success rate threshold, the flashing of the ECU to be flashed fails.

[0080] Exemplarily, the preset success rate threshold is 80%. If the flashing result display area 401 displays "8 successful flashing times, 2 failed flashing times", the flashing success rate of the ECU to be flashed is 8 / 10*100%=80%. Because 80% is equal to the preset success rate threshold, it can be determined that the flashing of the ECU to be flashed is successful; if the flashing result display area 401 displays "5 successful flashing times, 5 failed flashing times", the flashing success rate of the ECU to be flashed is 5 / 10*100%=50%. Because 50% is less than the preset success rate threshold, it can be determined that the flashing of the ECU to be flashed has failed.

[0081] In summary, the ECU flashing method provided by the embodiment of the present application solves the limitations of the current CANFD-ECU flashing test method and equipment limitations, and improves the flashing efficiency of the ECU; in addition, the method provided by the embodiment of the present application can use domestic flashing equipment, because the cost performance of domestic flashing equipment is high, so the method provided by the embodiment of the present application can save costs and improve economic benefits. Because the domestic flashing equipment can directly compile hex files, the method provided by the embodiment of the present application realizes security authentication (generating security algorithms) and hex file compilability, and the underlying logic of the OTA flashing test of the CANFD-ECU can be studied closely in this application, so that developers can modify the ECU flashing platform more intuitively and quickly, improving work efficiency.

[0082] Corresponding to the above embodiments, the present application also provides an ECU flashing device.

It can be a bus structure or a star structure, and can also include more or fewer components than shown in the figure, or combine certain components, or arrange components differently.

[0086] The flashing module 603 is used to flash the ECU to be flashed according to the ECU flashing platform and the address information of the ECU to be flashed.

[0087] In addition, in a possible implementation, the ECU flashing device further includes a verification module, and the verification module is used to verify whether the ECU flashing platform can successfully complete the flashing through a verification program.

[0088] Specifically, the inspection module is specifically used to inspect whether the ECU flashing platform can successfully complete the flashing through a first inspection program; if the first inspection program inspects that the ECU flashing platform can successfully complete the flashing, then inspect whether the ECU flashing platform can successfully complete the flashing through a second inspection program.

[0089] In addition, the inspection module is also used to flash the ECU to be flashed multiple times to determine whether the ECU to be flashed is successfully flashed.
