Detailed Description

The electronic control unit ECU is also called a computer control module, commonly called a driving computer, a vehicle-mounted computer, etc. An ECU can be said to be one of the core electronic components of a modern automobile. For example, an ECU of a car corresponds to a human brain and a CPU of a computer. The ECU is the cerebral nerve center system of the automobile. Typically under the dashboard of the driver's seat or near the wiper linkage. The ECU is used for monitoring various input data (such as braking, gear shifting and the like) and various running states (acceleration, slipping, oil consumption and the like) of the automobile at any time, calculating information sent by various sensors according to a pre-designed program, and sending various parameters to relevant execution mechanisms after processing so as to execute various preset control functions. For example, the ECU determines the optimum fuel injection amount after analyzing, budgeting, processing and storing according to the signals transmitted from the automobile sensors, and controls the fuel injection amount of the fuel injector, so that the automobile can always maintain the optimum air-fuel ratio, thereby improving the economy and the dynamic property and reducing the emission of tail gas. The initial ECU is used to control ignition and fuel injection at the beginning of the engine, and with the improvement of electronic automation of cars, the control range of the ECU is increasing, such as light control, airbag control, fuel heating control, exhaust control, brake control, exhaust Gas Recirculation (EGR), and the like. When the program in the ECU needs to be updated during the maintenance of the automobile, or when the parameters of part of the engine have problems and cannot be modified, the program stored in the ECU needs to be rewritten.

The current common ECU flash method is through the diagnostic device interacting with the vehicle ECU. The flash data is firstly downloaded from the network to the device, and then the diagnosis device divides the flash data into specific data so as to carry out one-to-one communication with the ECU. However, the 4-bit key of the vehicle is needed during communication, and the ECU can normally respond to all commands sent by the diagnostic equipment to successfully write. Such a single data interaction manner of question-and-answer often causes some problems.

For example, 1, network instability leads to data interaction errors; 2. ECU abnormal response causes data to be written in; 3. long interaction time (download data and ECU response time, etc.); 4. a key entry error results in a flush failure and ECU deadlock.

Therefore, the conventional ECU flash is not fast and convenient enough, flash data needs to be downloaded to diagnostic equipment, and then single command interaction is carried out through the equipment and the ECU. If network fluctuation occurs and the flash data is large, the waiting time is long. While also requiring the ECU to respond exactly to each piece of data. It should be noted that, because the number of the flash data is large, at most, the current communication device only supports the interactive command with the length of 0xFFF, and if the flash data exceeds the length, the communication device needs to be divided into a plurality of commands.

Therefore, the embodiment of the application provides an ECU flashing method, and the flashing data is directly flashed to the ECU through the guidance of a movable device. The slow interaction between the diagnostic equipment and the ECU is not needed any more, and the ECU writing efficiency is improved.

The data storage system may be integrated on the server 101, or may be placed on the cloud or other network server. For example, in the embodiment of the present application, the data storage system may store the flash data that the electronic control unit 103 needs to flash. The removable device 102 may be equipped with a file program that can direct the vehicle electronic control unit 103 to flash. At the same time, the removable device 102 can also place a profile ini that identifies the specific category of the electronic control unit 103 when the removable device 102 is connected to the electronic control unit 103.

The server 101 may be implemented as a stand-alone server or a server cluster composed of a plurality of servers. The removable device 102 may be a mobile phone, a computer, a usb disk, etc., and the specific entity of the removable device 102 is not limited herein. The electronic control unit 103 is a vehicle ECU. Specifically, the electronic control unit 103 may be an engine Electronic Control Module (ECM), a Body Control Module (BCM), an Instrument Panel (IPC), or the like, and a specific entity of the electronic control unit 103 is not limited herein.

It should be added that, in the embodiment of the present application, for convenience of describing the removable device 102, the following description of the removable device 102 describes a usb flash disk as a specific entity. It should be understood that the usb flash drive is used for convenience of description only, but is not limited to a specific physical device of the removable device 102, and accordingly, the removable device 102 only needs to be provided with a boot file program.

It should be further added that the number of the mobile devices 102 is not limited in the embodiment of the present application, that is, the server 101 may be simultaneously in communication connection with a plurality of mobile devices 102 through a network, and correspondingly, the mobile devices 102 may also be in communication connection with the electronic control unit 103, which is not described again in the following.

It should be understood that, for convenience of description, the server 101, the mobile device 102, and the electronic control unit 103 are not described in detail in the following, and the functions of the server 101, the mobile device 102, and the electronic control unit 103 are also not described in detail in the following. However, it should be noted that, for convenience of description and understanding, the description thereof is not repeated.

Referring to fig. 2, fig. 2 is a schematic flowchart of an ECU flashing method applied to a mobile device, including steps 201 to 203, according to an embodiment of the present application.

201. Target category data of the target ECU is identified.

As can be seen from the description of fig. 1 for the removable device, in this embodiment, the removable device may be a plurality of different devices, and for convenience of description, the description of the removable device in this embodiment is mainly described in terms of a usb disk, and is not described again in the following.

Firstly, a specific U disk is needed, and it should be noted that a removable device can be used, for example, the U disk is convenient. Correspondingly, the removable device may be provided with a boot file program.

When the USB flash disk is prepared, a configuration file is placed in the USB flash disk. When the USB flash disk is connected with the ECU through the USB interface of the USB flash disk, the configuration file in the USB flash disk can determine that the ECU is a specific type of the vehicle ECU. It should be noted that the specific category described in this embodiment is the target category data described in the above section.

202. And downloading the target flash data according to the target category data.

When the specific type of the vehicle ECU is identified, namely after the target type data of the vehicle ECU is acquired, the corresponding flash data can be downloaded from the server according to the target type data.

Specifically, the required target flash data can be downloaded to the server according to the target category data, that is, which ECU needs to be flashed to download the corresponding flash data.

For example, in step 201, if the identified ECU is an ECM, the server is connected to the usb disk, and then the flash data corresponding to the ECM is downloaded from the server. Rather than downloading flash data for other ECU classes. It should be noted that the present embodiment does not limit the specific category of the ECU, and the category included in the ECU may be BCM, IPC, or the like.

Further, each U disk downloads only the flash data corresponding to one vehicle ECU class.

203. And calling a flash program stored in the removable device, and flashing the target flash data into the target ECU.

After the target flash data is downloaded from the USB flash disk, the USB flash disk is connected with the vehicle ECU, and specifically, the USB flash disk can be directly inserted into a USB interface of a vehicle. Therefore, the flash disk can call the flash program stored in the flash disk, and correspondingly, the internal program is activated, so that the target flash data is flashed to the ECU.

Furthermore, after the brushing data is successfully brushed, a prompt tone can be sent out, so that the user is reminded of finishing brushing.

According to the ECU flashing method provided by the embodiment, the target type data of the target ECU are identified, the target flashing data are downloaded according to the target type data, and finally the flashing program stored in the mobile equipment is called, so that the target flashing data are flashed into the target ECU. Therefore, the ECU data can be refreshed by using the mobile equipment without the diagnosis equipment, the ECU data refreshing method is convenient and fast, the ECU refreshing efficiency is improved, and the experience of a user is improved.

The following describes in detail a method for flashing an ECU according to an embodiment of the present application. Referring to fig. 3, fig. 3 is a schematic flow chart of another ECU flashing method disclosed in the embodiment of the present application. Including step 301-step 308. It should be noted that, in the present embodiment, for convenience of description, only one of the ECUs is described, and correspondingly, the mentioned ECU may be understood as a target ECU, which is not described again in the following.

301. When the mobile device establishes communication connection with the target ECU, the product identification code of the target ECU is read according to the pre-configured identification file so as to identify the target category data.

As can be known from the description of fig. 1 for the removable device, in this embodiment, the removable device may be a variety of different devices, and for convenience of description, the description for the removable device in this embodiment is mainly described in a usb flash disk, and is not described again in the following.

Firstly, a specific U disk is needed, and it should be noted that any removable device can be used, and the U disk is convenient to use for example. Correspondingly, the mobile device is provided with a boot file program.

Specifically, a program capable of guiding the vehicle ECU to write a file in a flash mode is recorded in the USB flash disk. The program for guiding the vehicle ECU to write the file in a flashing manner is the writing program described in the above section, and the program is similar to the EXE file, and as long as the program is inserted into the USB interface of the ECU, the corresponding program can be automatically loaded, so that the corresponding program instruction is executed.

And after the burning and programming program is finished, placing a configuration file ini into the U disk. When the USB flash disk is connected with the ECU through the USB interface of the USB flash disk, the configuration file in the USB flash disk can determine that the ECU is the specific type of the vehicle ECU, namely determine which ECU writes the vehicle. It should be noted that the specific category described in this embodiment is the target category data described in the above section.

Since the ini file is generally an initialization file and a plurality of ECUs exist in the vehicle, the ini file needs to be used to distinguish the ECUs. It should be further noted that, when configuring the ini, the identification files of all the vehicle ECU categories may be configured into the ini file, such as the flash engine, and the configuration file configures the ECM, the body BCM, the meter IPC, and the like.

Further, when the profile ini is configured, only one identification file of the vehicle ECU type may be configured. In other words, the usb flash drive may become a removable device dedicated to one type of vehicle ECU.

Therefore, after the USB flash disk configuration identification file is completed, the USB flash disk is inserted into the USB interface of the vehicle ECU, and therefore the mobile device is in communication connection with the vehicle ECU. At this time, the configured identification file in the usb flash disk, specifically, the configured ini file, can read the identification information of the ECU, so as to determine the specific category of the vehicle ECU.

Furthermore, after the configured ini file is operated, the product identification code of the ECU can be read, so that the product identification code is compared with the configuration file in the ini file, and finally the specific type of the vehicle ECU can be identified.

302. And downloading the ciphertext data of the target flash data from the server according to the target category data.

After the specific types of the vehicle ECUs are identified, the required flash data can be downloaded from the vehicle information to the website, and which ECU needs to be flashed and which is downloaded. It should be noted that the vehicle information is the target category data described in the above section, that is, the specific category of the vehicle ECU.

Specifically, after the specific category of the vehicle ECU is identified, the target rewriting data is downloaded from a website in the server (the website may be a website operated by a manufacturer of the vehicle ECU, or a website operated by another company, which is not limited in this embodiment, and only the rewriting data corresponding to the ECU exists on the website).

For example, in step 301, when the recognized ECU is an ECM, the server is connected to the usb disk, and then the flash data corresponding to the ECM is downloaded from the server. Rather than downloading other ECU classes of flash data. It should be noted that the present embodiment does not limit the specific type of the ECU, and the type included in the ECU may be BCM, IPC, or the like.

It should be added that, because of the importance of confidentiality, the data on the web is encrypted for security, and the flash data on the web site generally exists in the form of a ciphertext. Therefore, the flash data downloaded from the server according to the specific category of the vehicle ECU is ciphertext data corresponding to the target flash data.

303. And decrypting the ciphertext data according to the identification file to obtain the plaintext data of the target flash data.

In the process of downloading the target flash data, the configured ini file can decrypt the downloaded ciphertext data, so that the ciphertext data is decrypted into plaintext data. At this time, plaintext data of the target flash data can be acquired.

It should be noted that the target write data at this time is a binary file that can be recognized by the vehicle ECU.

Further, the configured ini file may be decrypted only for one vehicle ECU class of flush data. In other words, the usb flash drive may become a removable device dedicated to one type of vehicle ECU.

304. When the removable device establishes a communication connection with the target ECU, the target ECU is booted according to the flash program so that the target ECU flashes plaintext data of the target flash data.

After the target flash data is downloaded from the USB flash disk, the USB flash disk is connected with the vehicle ECU, and specifically, the USB flash disk can be directly inserted into a USB interface of a vehicle. The U disk activates an internal flash program, so that flash data is flashed into the ECU.

Specifically, after downloading the target brushing data is completed, the USB flash disk is directly inserted into a USB interface of the vehicle ECU, and the USB flash disk starts a brushing program, so that the USB flash disk is automatically guided to execute a brushing instruction, and plaintext data of the target brushing data is brushed into the vehicle ECU.

305. And calling a flash program stored in the removable device, and flashing the target flash data into the target ECU.

Specifically, plaintext data of the target flash data may be flashed into the target ECU.

Further, if it is detected that the target data flash to the target ECU fails, step 306 is executed.

If it is detected that the target data flashing to the target ECU is successful, step 308 is executed.

306. And when failure of the target flashing data to the target ECU is detected, calling an exit instruction in the flashing program, deleting the flashed target flashing data, and stopping flashing the target flashing data to the target ECU.

When the target data is in the process of being flashed to the vehicle ECU, the flashing fails, that is, when a flashing error occurs midway, the boot program may need to be forcibly exited. Note that the boot program is the flash program described in the supplement.

When the flash fails, the normal exit should be performed first. Specifically, when the flash fails, the flash program in the usb disk may call an automatic exit program in the flash program. It should be noted that the automatic exit program is the exit instruction described in the above section.

When the corresponding exit instruction is executed, the flash disk also executes the target flash data which is flash written in the ECU in the flash program, and it is understood that only a part of the target flash data exists in the vehicle ECU at the moment, and the target flash data of the part is deleted by the flash disk at the moment.

Further, if the copying of the data for 3 consecutive times to the vehicle ECU is not successful, it is determined that the flashing has failed, and the automatic exit routine is executed. It should be added that, in the present embodiment, after 3 consecutive times of copying of the flash data to the vehicle ECU fail, 3 consecutive times of the automatic exit program are executed, which is only one of the embodiments that can be implemented specifically, but the automatic exit program is executed without indicating that 3 consecutive times of flash fails, and may also be executed 4 consecutive times or 5 consecutive times, and the like, and the present embodiment does not limit this.

Further, the U disk can be directly pulled out, so that forced exit is realized.

When the flash data of the vehicle ECU which is already flashed is cleared, the USB flash disk does not execute the corresponding flash program any more. Thus, the U disk stops flashing the target flash data to the ECU.

307. It is checked whether the identification file and the target write-through data are correct.

If the flash fails and the target flash data which has been flashed is deleted, the flash needs to be flushed to perform the flash. Specifically, it is necessary to check whether the ini configuration file in the identification file is correct or not, and whether the downloaded target write data is consistent with the write data on the server or not.

If the identification file and the target flush data are correct, step 305 is executed again.

If any one of the identification file and the target flash data has an error or data error, the identification file needs to be reconfigured or the target flash data needs to be downloaded again. That is, step 301 is performed to reconfigure the identification file, or step 302 is performed to re-download the target flash data.

Specifically, if the identification file is incorrect, the ini profile is deleted, and the ini profile is reconfigured, so that the flush data of the specific ECU can be downloaded.

Furthermore, when the identification file and the target flashing data are correct, namely, the identification file and the target flashing data are confirmed to be correct, the target ECU can be flashed again.

308. And when the target flashing data is successfully flashed to the target ECU, deleting the target flashing data.

When the target flash data is flashed into the target ECU and the flash is successfully flashed, the USB flash disk deletes the stored flash data.

Furthermore, after the flash is successful, a prompt tone is given out, so that the user is reminded of finishing the flash. It is added that the instrument interface of the vehicle can also prompt the successful message of the flash. It should be understood that the prompt information after the completion of the flash is not limited in this embodiment, and is not further described in the following.

According to the ECU flashing method provided by the embodiment, under the condition that no diagnosis equipment is available, ECU data can be flashed by using specific movable equipment, convenience and rapidness are achieved, and ECU flashing efficiency is improved. Meanwhile, when the data flashing fails, the data flashing can be downloaded again, and the realizability of the scheme is improved.

It should be understood that, although the steps in the flowcharts related to the embodiments as described above are sequentially displayed as indicated by arrows, the steps are not necessarily performed sequentially as indicated by the arrows. The steps are not limited to being performed in the exact order illustrated and, unless explicitly stated herein, may be performed in other orders.
