A flow diagram of an engine ECU flashing and flashing diagnostic method according to an embodiment of the present application is shown in fig. 3.
In order to better explain the engine ECU flashing and flashing diagnosis method of the present application, as shown in fig. 3, when implemented, the flashing diagnosis device includes a service, a TBOX remote terminal and a diagnosis instrument. The ECU flash device includes two parts, BT and ASW.
Firstly, when the ECU is flushed, the diagnostic instrument can acquire the flushed data from the server, execute the flushing process and infuse the data in the server into the ECU. The diagnostic instrument proposed here is an authorized diagnostic instrument that can be connected to an enterprise server, whereas other swipe tools cannot be connected to the enterprise server.
Then BT is responsible for ECU flash and ASW is responsible for ECU control.
The ASW is responsible for forming a temporary record of the number of times of flashing, the item number, the version number, and the ECU operating time and storing the temporary record in the memory EE. And the BT executes a flash process, and sets the temporary record as a formal record when the corresponding area begins to be erased.
After the flash is finished, storing the flash record; the flash recording function in the ECU can record the latest three times of flash information, including the flash times, the item numbers, the version numbers and the ECU running time.
And after the ECU is restarted, the ECU can be actively informed of the TBOX by using a J1939 message broadcasting mode, the flash record is stored in the server, and the server records the flash finishing time, the flash times, the item number, the version number and the ECU running time.
Then, when the ECU is subjected to the flash diagnosis, the server is responsible for ECU data management and can provide information of the ECU flash record, including the ECU serial number, the data record number, the record issuing time, the flash finishing time, the flash times, the project number, the version number, the ECU running time and the like. The flash record information can be self-defined.
When the vehicle needs to be maintained, the diagnostic instrument is accessed to perform fault reading and troubleshooting, at the moment, the diagnostic instrument reads the flash record in the ECU through 0x22 service and transmits the information to the server, if the server already comprises the latest flash record, the information is discarded, and otherwise, the record is recorded.
When the flash record in the server does not include the data record number and the issued record time, the illegal flash information is determined, and the time of the flash can be roughly estimated through the current ECU running time, the previous ECU running time and the previous flash finishing time.
And when the ECU is judged to be illegally written, the server performs early warning to help service personnel to recover normal data so as to protect the vehicle.
Therefore, the ECU can actively record the flash information, and all the flash can be captured; the information validity record is executed from the execution of the flash flow to the erasure, so that the flash record is more accurate; temporary records can be formed in advance, and the situation that the records cannot be formed again due to the failure of the flash is avoided; after the flash is finished, a message is sent out, so that the TBOX can conveniently and timely inform a server; the information related to the ECU flash record can be read in both BT and ASW.
The ECU flash method of the engine is applied to ECU flash equipment and comprises the following steps: receiving an ECU (electronic control unit) flashing request instruction; forming a temporary brushing record in advance according to the ECU brushing request instruction, and storing the temporary brushing record; executing ECU (electronic control unit) flash according to the flash temporary record; and automatically recording to form a first ECU flash record after the ECU flash is finished, and sending the first ECU flash record to the outside. The application can actively record the flash information; the brushing record information can be self-defined, and different requirements are met; a temporary record is formed in advance, so that the condition that the record cannot be formed again due to the failure of the flash is avoided; and after the flash is finished, the J1939 message is sent out, so that the situation that the recording cannot be carried out when the flash fails is avoided.
And therefore has the technical effect of: the method meets different customer requirements, avoids failure of flash writing, incapability of forming records again, more accurate flash writing records and the like.
The method for diagnosing the flash of the ECU of the engine is applied to flash diagnosis equipment and comprises the following steps: receiving a flash diagnosis request instruction; acquiring a first ECU (electronic control unit) flash record obtained by an ECU flash method of the engine according to the flash diagnosis request instruction; and when the corresponding second ECU flash record in the flash diagnosis equipment lacks the data record number and/or the issuing record time of the first ECU flash record, judging the ECU flash record as an illegal flash record. The problem of whether the ECU of the vehicle is stolen to brush or not can not be determined in the prior art is solved.
