[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] In the prior art, the Electronic Control Unit (ECU) is an important part of modern cars, which controls the operation of the engine and various functions of the vehicle; replacing the ECU can improve the performance and driving experience of the car. In addition, the car also needs to replace the ECU when the ECU fails or is damaged. Usually, after the ECU of a car is replaced, it is necessary to copy the coding information, that is, to copy and save the information of the original ECU, and then write the copied coding information to the replaced new ECU after replacing the new ECU. However, if the original ECU is completely damaged at this time, such as being soaked in water and unable to operate, the coding data of the original ECU cannot be obtained, and effective replacement cannot be achieved without writing the coding data into the new ECU. Therefore, how to improve the success rate of obtaining coding data, and then improve the success rate of replacing the ECU, is a problem that needs to be solved urgently.

[0042] The embodiment of the present application discloses a method for replacing an electronic control unit. Referring to FIG1 , the method may include the following steps:

[0043] Step S11: Acquire vehicle information of a target vehicle whose electronic control unit is to be replaced.

[0044] First, obtain the vehicle information of the vehicle that needs to replace the electronic control unit. The information can be obtained through diagnostic equipment. The above vehicle information includes the vehicle identification number (VIN), model information, year information (i.e. production and release year information), system information, etc.

[0045] Step S12: Check the coding data of the original electronic control unit of the target vehicle. If the coding data of the original electronic control unit cannot be successfully read, search the server for the coding data of the electronic control unit of the matching vehicle corresponding to the target vehicle based on the vehicle information and preset matching conditions; the preset matching conditions include matching conditions of vehicle model, year and system.

[0046] Replacing an electronic control unit requires writing the coded data in the original electronic control unit into a new electronic control unit. The simplest way is to directly read the coded data in the original electronic control unit on the target vehicle. However, in many cases, the electronic control unit is replaced because the electronic control unit is damaged, and the coded data cannot be directly read from the original electronic control unit. This embodiment selects a method for obtaining the coded data based on whether the coded data of the original electronic control unit can be successfully read.

[0047] Specifically, if the coded data can be read successfully, the read coded data is encrypted and saved locally, and the encrypted coded data is uploaded to the server. That is, if the coded data can be read, it is directly read from the original electronic control unit, and in order to ensure the security of the coded data, the read coded data is encrypted and saved; at the same time, the encrypted coded data is uploaded to the server so that other vehicles can obtain it from the server when needed. The server contains various types of coded data, which can be uploaded by different vehicles or pre-stored by the administrator.

[0048] In this embodiment, if the coding data cannot be successfully read from the server, the server is queried whether there is matching coding data based on the vehicle information of the target vehicle; it can be understood that if the vehicle model, year and system are the same, the coding data of the vehicle's electronic control unit is also the same, so the coding data of the original electronic control unit is obtained by querying the server whether there is coding data of a matching vehicle.

[0049] In some embodiments, the reading method of the coded data can be achieved through a status identifier. Specifically, before checking the coded data of the original electronic control unit of the target vehicle, it can also include: initializing the status identifier; the identifier is used to characterize the reading method of the coded data; accordingly, checking the coded data of the original electronic control unit of the target vehicle includes: if the coded data of the original electronic control unit can be successfully read, then updating the status identifier to a first identifier, so as to directly read the coded data of the original electronic control unit according to the first identifier; if the coded data of the original electronic control unit cannot be successfully read, then updating the status identifier to a second identifier, so as to search for whether the coded data of the electronic control unit of the matching vehicle corresponding to the target vehicle exists in the server according to the second identifier combined with the vehicle information and the preset matching conditions. For example, the initialization status identifier is 0. If the coded data of the original electronic control unit is successfully read, the status identifier is set to 1. If the coded data of the original electronic control unit cannot be read, the status identifier is set to 2. After replacing the electronic control unit, the status identifier is judged. If the status identifier is 0, it is prompted to replace the original electronic control unit. If the identification status is 1, the local file data is directly obtained, decrypted by the decryption algorithm, and the new electronic control unit data is written. If the identification status is 2, the vehicle of the same model, the same year and matching the same system is searched from the diagnostic platform server to determine whether there is data of the electronic control unit.

[0050] In some embodiments, before uploading the encrypted coded data to the server, the process may further include: displaying a data upload request through a human-computer interaction interface; receiving a request consent instruction issued by a user through the human-computer interaction interface, and performing the operation of uploading the encrypted coded data to the server according to the request consent instruction. That is, in order to ensure user privacy, the user's consent may be sought through the human-computer interaction interface before uploading, and data uploading may be performed with the user's consent.

[0051] Step S13: If it exists, the coding data of the matching vehicle is used as the coding data of the original electronic control unit.

[0052] The matching coding data in the server is used as the coding data of the original electronic control unit, so that the coding data can be written into the new electronic control unit after the new electronic control unit is replaced.

[0053] In some embodiments, after searching the server for the coding data of the electronic control unit of the matching vehicle corresponding to the target vehicle, the process may also include: if the coding data corresponding to the matching vehicle does not exist in the server, sending a data request order to the order platform based on the vehicle information; receiving the coding data sent by the matching vehicle corresponding to the target vehicle according to the data request order, and issuing a reward to the user corresponding to the matching vehicle through the order platform; the matching vehicle is used to obtain the data request order from the order platform, and read the coding data of its own electronic control unit according to the data request order.

[0054] That is, in this embodiment, by constructing an order platform, when the user cannot obtain the coded data from the original electronic control unit and the server, the user can initiate a data request order to the order platform. After seeing the order on the order platform, other vehicle users can accept the order and return the corresponding coded data. Specifically, if the user of other vehicles has entered the vehicle information on the order platform, the data request order can be directly sent to the user of the matching vehicle that matches the target vehicle; if the user has not entered it, the order is public and can be viewed by any user who logs in to the order platform. After accepting the order, the user of the matching vehicle reads the coded data of the electronic control unit of the matching vehicle and sends the data to the target vehicle. After receiving the data, the target vehicle issues a reward to the user corresponding to the matching vehicle through the order platform, such as a transfer.

[0055] In some embodiments, the receiving of the coded data sent by the matching vehicle corresponding to the target vehicle according to the data request order may include: receiving the coded data sent by the vehicle diagnostic device of the matching vehicle through the vehicle diagnostic device of the target vehicle. That is, the target vehicle may directly contact the matching vehicle, through the diagnostic device, or through other devices that can contact.

[0056] In some embodiments, the receiving of the coded data sent by the matching vehicle corresponding to the target vehicle according to the data request order may include: obtaining the coded data uploaded to the server by the matching vehicle according to the data request order by querying the server. That is, after the matching vehicle accepts the order, it uploads the coded data to the server, and the user of the target vehicle can read the coded data from the server after paying.

[0057] Step S14: after replacing the original electronic control unit of the target vehicle with a new electronic control unit, writing the coding data of the original electronic control unit into the new electronic control unit.

[0058] After detecting that the original electronic control unit of the target vehicle is replaced with a new electronic control unit, the acquired coded data is written into the new electronic control unit.

[0059] As can be seen from the above, in this embodiment, the vehicle information of the target vehicle to be replaced with the electronic control unit is obtained; the coding data of the original electronic control unit of the target vehicle is checked; if the coding data of the original electronic control unit cannot be successfully read, then according to the vehicle information and the preset matching conditions, the server is searched for the coding data of the electronic control unit of the matching vehicle corresponding to the target vehicle; the preset matching conditions include the matching conditions of the vehicle model, year and system; if it exists, the coding data of the matching vehicle is used as the coding data of the original electronic control unit; after the original electronic control unit of the target vehicle is replaced with a new electronic control unit, the coding data of the original electronic control unit is written into the new electronic control unit. It can be seen that since the coding data of vehicles with the same vehicle model, year and system are the same, by obtaining the vehicle information of the vehicle, when the coding data cannot be directly read from the electronic control unit, according to the vehicle information, the vehicle model, year and system are used as the screening conditions to check whether the coding data of the electronic control unit of the matching vehicle corresponding to the target vehicle exists in the server, and the coding data is written into the new electronic control unit, so as to realize the effective replacement of the electronic control unit, and solve the problem that the original electronic control unit is damaged and the coding data cannot be directly read, resulting in the failure of the replacement of the electronic control unit.

[0060] Based on the above embodiments, the embodiments of the present application disclose a specific method for replacing an electronic control unit, which is applied to a diagnostic device. The method may include the following steps:

[0061] S201: Obtain vehicle information through diagnostic equipment, including vehicle identification number VIN, model, year, system, etc., and initialize the state flag to 0;

[0062] S202: Before replacing the ECU, read the ECU data and set the status flag according to the data reading result. If the reading is successful, set the status flag 1, encrypt the read coded data through the encryption algorithm and save it to the local file, and automatically upload or ask whether to upload the coded data to the diagnostic platform server. If the reading cannot be done, set the status flag 2.

[0063] S203: After replacing the ECU, read the status identification. If the status identification is 0, it will prompt to replace the old ECU and read the ECU data; if the identification status is 1, directly obtain the local file data, decrypt it through the decryption algorithm, and write the ECU data; if the identification status is 2, search for vehicles of the same model and year from the diagnostic platform server, match the same system, and determine whether there is ECU data;

[0064] S204: If the diagnostic platform server has matching coded data, the data is downloaded and read, and decrypted using a decryption algorithm;

[0065] S205: If the diagnostic platform server does not have matching coding data, an order is initiated according to the vehicle model, year, and system, that is, a request for reading the coding data before replacing the ECU of the same model and system ECU is sent, and the order is waited for.

[0066] S206: The vehicle matching the target vehicle acts as the order taker, receives the order according to the vehicle model, year, and system, reads its own ECU data, and informs the order initiator of the method for sending the coded data. There are two methods for sending the coded data. Method 1 is to transmit the local file to the order initiator, such as directly sending the coded data to the target vehicle through an interrupt device; Method 2 is to upload the data to the diagnostic platform server.

[0067] S207: The order initiator sets the status identifier according to the encoding data sending method, such as setting the status identifier 1 for method 1 and setting the status identifier 2 for method 2;

[0068] S208: The target vehicle reads the status identification again. If the identification status is 1, the local file data is directly obtained, decrypted by the decryption algorithm, and written into the ECU data; if the identification status is 2, the coding data of the vehicle of the same model, year and matching the same system is searched from the diagnostic platform server until the ECU data is successfully written.

[0069] S209: The electronic control unit is replaced.

[0070] As can be seen from the above, in this embodiment, the feature that the coded data of vehicles with the same model, year and system are the same is utilized. By acquiring the vehicle information of the vehicle, when the coded data cannot be directly read from the electronic control unit, the model, year and system are used as screening conditions according to the vehicle information to check whether there is coded data of the electronic control unit of the matching vehicle corresponding to the target vehicle in the server, and the coded data is written into the new electronic control unit to achieve effective replacement of the electronic control unit. If there is no matching coded data on the current server, a data acquisition request is initiated in the form of an order so that it can provide the coded data after receiving the order from the user, which can solve the problem that the original electronic control unit is damaged and the coded data cannot be directly read, resulting in the failure of replacing the electronic control unit.

[0071] Correspondingly, the embodiment of the present application further discloses an electronic control unit replacement device, as shown in FIG2 , the device includes:

[0072] The vehicle information acquisition module 11 is used to acquire the vehicle information of the target vehicle whose electronic control unit is to be replaced;

[0073] The coding data viewing module 12 is used to view the coding data of the original electronic control unit of the target vehicle.

[0075] The coding data writing module 14 is used to write the coding data of the original electronic control unit into the new electronic control unit after the original electronic control unit of the target vehicle is replaced with a new electronic control unit.

[0076] As can be seen from the above, in this embodiment, the vehicle information of the target vehicle to be replaced with the electronic control unit is obtained; the coding data of the original electronic control unit of the target vehicle is checked; if the coding data of the original electronic control unit cannot be successfully read, then according to the vehicle information and the preset matching conditions, the server is searched for the coding data of the electronic control unit of the matching vehicle corresponding to the target vehicle; the preset matching conditions include the matching conditions of the vehicle model, year and system; if it exists, the coding data of the matching vehicle is used as the coding data of the original electronic control unit; after the original electronic control unit of the target vehicle is replaced with a new electronic control unit, the coding data of the original electronic control unit is written into the new electronic control unit.
