[0042] In order to make the objects, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0043] As shown in Figure 1 and Figure 2 The present application discloses an ECU flashing test error detection method, comprising the following steps:

[0044] S10, the host computer performs data verification on the flashing file according to the first verification logic, and obtains a first verification result;

[0045] S20, running the flashing software, performing the flashing operation on the flashing file, and at the same time, running the message monitoring tool, obtaining the outgoing message of the flashing file before the flashing file is flashed to the ECU;

[0046] S30, the message monitoring tool performs data verification on the outgoing message according to the second verification logic, and obtains a second verification result;

[0047] S40, comparing the first verification result and the second verification result, if the second verification result is contained in the first verification result, it is determined that the flashing is successful; if the second verification result contains other data except the first verification result, it is determined that the flashing fails.

[0048] In the present application, the first verification logic includes directly obtaining the first start address and the first end address pre-flashed to the ECU from the flashing file.

[0049] The flashing file is programmed by development software, and the programming contains the flashing instruction of the Flash area in the ECU, including the first start address and the first end address.

[0050] The second verification logic includes obtaining the erase instruction from the outgoing message, screening the valid information contained in the erase instruction, and obtaining the second start address, the second end address and the second space value pre-erased to the ECU from the valid information.

[0051] The message monitoring tool is the BUSMASTER monitoring software.

[0052] Preferably, the first verification result includes the first start address, the first end address, and the first space value required for flashing generated according to the first start address and the first end address;

[0053] The second verification result includes the second start address, the second end address and the second space value.

[0054] Preferably, in step S40, comparing the first verification result and the second verification result includes:

[0055] S41, separately comparing the first starting address, the first ending address, and the first space value with the second starting address, the second ending address, and the second space value;

[0056] S42, determining the erase area value based on the second start address, the second end address, and the second space value;

[0057] S43: Determine whether the erase area value is in the flash file.

[0058] In the present invention, both the first and second space values ​​represent the areas of the ECU's Flash area that need to be flashed or erased. For example, if the first verification result indicates a first space value of 10 segments, this indicates that the flash file needs to erase 10 segments of the Flash area for data storage. If the second verification result indicates a second space value of 8 segments, this indicates that only 8 segments of the Flash area will be erased during the flashing process. If the 8 segments of space are contained within the 10 segments of space, the ECU flash will not fail or "flash freeze," and the flash is therefore determined to be successful. If the erased space exceeds 10 segments during the flashing process, the ECU will fail or "flash freeze," causing damage to the ECU.

[0059] Preferably, an error prompt is also included, and the steps are as follows:

[0060] S50: Determine that the flashing fails, and give a prompt through the host computer that the flashing address and the flashing data do not match.

[0061] Before the flash file is written to the ECU, the present invention can verify and detect the flash file in advance to prevent the ECU from being flashed or "flashed" due to mismatch in the flashing mode after the flash file is written to the ECU, thereby preventing the subsequent test progress from being affected and improving the efficiency of flash error screening.

[0064] The outgoing message acquisition module 62 is used to obtain the outgoing message of the flash file before the flash file is flashed to the ECU;

[0067] Preferably, the device further comprises a prompt output module 65.
