It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments described here can be implemented in an order other than those illustrated or described here. In addition, the term "comprising" or "having" and any variation thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0051] For ease of understanding, the specific process of the embodiments of the present invention will be described below. Please refer to Figure 1 , the first aspect of the present invention provides a method for converting vehicle control protocols, including:

[0052] S100. In response to the addition of an API interface, use the project vehicle control instruction to access the old supplier vehicle control API interface and the newly added supplier vehicle control API interface respectively; in the present invention, for the convenience of vehicle control protocol management, the API interfaces of all suppliers can be maintained in an API interface set, and the changes in the set are monitored in real time. When there is a newly added API interface in the API interface set, the system is triggered to automatically use the project vehicle control instruction to access the old supplier vehicle control API interface and the newly added supplier vehicle control API interface respectively. It should be noted that the old supplier vehicle control API interface here in the present invention can be a benchmark supplier vehicle control API interface specified in advance by humans. The benchmark supplier vehicle control API interface can be the earliest vehicle control API interface added to the API interface set. All subsequent newly added vehicle control protocols will be converted into the vehicle control protocol of the benchmark supplier vehicle control API interface. In the present invention, the project vehicle control instruction can be an interface access instruction compatible with all manufacturers. After receiving the project vehicle control instruction, it will automatically send its own vehicle control protocol to the vehicle control protocol conversion system.

[0053] S200. Receive the old vehicle control protocol and the newly added vehicle control protocol returned by the old supplier vehicle control API interface and the newly added supplier vehicle control API interface respectively; in the present invention, after the old supplier vehicle control API interface receives the project vehicle control instruction, it will automatically return the old vehicle control protocol (i.e., the benchmark vehicle control protocol) it has to the vehicle control protocol conversion system, and the newly added supplier vehicle control API interface will return the newly added vehicle control protocol it has to the vehicle control protocol conversion system. In the present invention, the old vehicle control protocol and the newly added vehicle control protocol can be vehicle control protocols defined in json format.

[0054] S300. Remove fields and replace fields according to preset rules for the newly added vehicle control protocol to obtain newly added protocol verification data. In the present invention, before establishing the relationship between the newly added vehicle control protocol and the old vehicle control protocol, certain processing is performed on the newly added vehicle control protocol to obtain useful verification data in the newly added vehicle control protocol, thereby avoiding the problem that the verification process is easily cracked when directly processing the newly added vehicle control protocol.

[0055] In an optional implementation manner of step S300 of the present invention, the removing fields and replacing fields according to preset rules for the newly added vehicle control protocol to obtain newly added protocol verification data includes:

[0056] S301. Traverse each field in the newly added vehicle control protocol and determine whether the field belongs to a necessary field. The basis for determining whether the field is a necessary field can be whether the field is meaningful in the specific control of the protocol. In other words, it is whether the field is meaningful in guiding control. Therefore, in an exemplary implementation manner of the present invention, this step may include: traversing each field in the newly added vehicle control protocol and determining whether the field is the target field defined by the parameter; if the field is the target field defined by the parameter, it is determined that the field is a necessary field; if the field is not the target field defined by the parameter, it is determined that the field is a non-necessary field. It should be noted that the parameter definition in the present invention can be a function definition or a numerical value and range definition.

[0057] S302. If the field does not belong to the necessary fields, remove the field from the newly added vehicle control protocol. In this implementation manner of the present invention, when the newly added vehicle control protocol extracts verification information, fields that are meaningless for vehicle control in the protocol are deleted, that is, the present invention only retains the valid fields in the newly added vehicle control protocol.

[0058] S303. If the field belongs to the necessary field, the type of the field is further obtained. If the type of the field belongs to the target type, the field is replaced with a fixed field. If the type of the field does not belong to the target type, the field is not processed. In the present invention, after eliminating the meaningless fields in the newly added vehicle control protocol, the remaining fields in the newly added vehicle control protocol are further processed. Specifically, this step may include: if the field belongs to the necessary field, the type of the field is further obtained; if the type of the field is text type, the field is replaced with a fixed field; if the type of the field is an enumeration type, the field remains unchanged. In the present invention, the way to further process the remaining fields in the newly added vehicle control protocol is to set the text type fields (infinite content) in the remaining fields to fixed content, such as NULL. The advantage of the present invention is that it can further retain the meaningful fields in the newly added vehicle control protocol, reduce the amount of data processing required for subsequent hash operations, and thus improve data processing efficiency.

[0059] S400, performing a hash operation on the newly added protocol verification data to obtain a newly added protocol hash code; a hash operation (Hash Function) is a mathematical function that converts input data of any length into a fixed-length output (hash value). It has the characteristics of irreversibility, uniqueness (anti-collision) and determinism, and is widely used in fields such as data integrity verification, password storage, and digital signatures. Using a hash operation on the newly added protocol verification data can ensure the standardization of generated data. In the present invention, the hash algorithms used can be MD5, SHA-1, and SHA-256, and SHA-256 can be used as an example.

[0060] S500, constructing a map mapping table between the newly added protocol hash code and the old vehicle control protocol; in the present invention, the newly added protocol hash code is used as the identifier of the new protocol to replace the new protocol and the old protocol for relationship binding, and the newly added protocol hash code replaces the overall content of the new protocol to construct the map mapping table, which can reduce the storage volume of the mapping table data while ensuring the uniqueness of the mapping between the new and old protocols. In an optional implementation of the first aspect of the present invention, the construction of the map mapping table between the newly added protocol hash code and the old vehicle control protocol includes: using the newly added protocol hash code as the key value and the old vehicle control protocol as the value value, performing key-value binding between the newly added protocol hash code and the old vehicle control protocol to obtain a map mapping table. In the present invention, after the map mapping table is constructed, the subsequent terminal control request can match the corresponding old protocol in the map mapping table according to the protocol it carries, thereby converting it into the corresponding old protocol to control the vehicle-mounted product.

[0061] S600. When receiving a vehicle control request from a user terminal, extract the protocol verification data of the vehicle control protocol used in the vehicle control request, and perform a hash operation to obtain a request protocol hash code; in the present invention, the method for obtaining the protocol verification data of the vehicle control protocol used in the vehicle control request is the same as the method for obtaining the verification data of the new vehicle control protocol, and the specific algorithm used in the hash operation is also the same. In this way, it can be ensured that the request protocol hash code finally obtained from the vehicle control protocol used in the vehicle control request can be accurately matched if there is a recorded new vehicle control protocol in the map mapping table. Specifically, step S600 of the present invention may specifically include: parsing the vehicle control request of the user terminal to obtain the vehicle control protocol used in the vehicle control request; performing field removal and field replacement processing on the vehicle control protocol used in the vehicle control request according to the preset rules to obtain protocol verification data; performing a hash operation on the protocol verification data to obtain a request protocol hash code.

[0062] S700. Based on the request protocol hash code, obtain a target old vehicle control protocol from the map mapping table for vehicle control. In the present invention, the protocol used in the vehicle control request of the user terminal may not belong to the recorded new vehicle control protocol. Therefore, in this step, there are also two results for whether a target old vehicle control protocol can be matched. Specifically, step S700 of the present invention may include: determining whether there is a target hash code recorded in the map mapping table that is the same as the request protocol hash code; if there is a target hash code recorded in the map mapping table that is the same as the request protocol hash code, obtain a target old vehicle control protocol based on the target hash code for vehicle control; if there is no target hash code recorded in the map mapping table that is the same as the request protocol hash code, generate an alarm to prompt that the vehicle control protocol has changed and the old vehicle control protocol cannot be compatible.

[0063] Generally speaking, the specific idea of the vehicle control protocol conversion method of the present invention can be summarized as follows:

[0064] 1. Obtain the interface API of the old supplier, obtain the interface API of the new supplier, and obtain the project vehicle control instruction.

[0065] 2. Use the vehicle control instruction to request the interface APIs of the old supplier and the new supplier, record the results on both sides respectively, and call them the old protocol and the new protocol respectively.

[0066] 3. For each field of the new protocol:

[0067] 3.1 If this field is not necessary, directly remove it.

[0068] 3.2 If this field is necessary, then perform the following operations.

[0069] 3.2.1 If it is text type (unlimited content), set it to a fixed content, such as NULL.

[0070] 3.2.3 If it is an enumeration type, keep it unchanged.

[0071] 4. Perform a hash operation on the remaining content of the new protocol and save it as the new protocol key for the information to be verified in the new protocol.

[0072] 5. Use the new protocol key as the hash key and the content of the old protocol as the hash value, and save this map mapping.

[0073] 6. When a user requests the new protocol using a vehicle control command, obtain the instruction key according to the rules in steps 3 and 4, and find the old protocol from the map table in step 5 to achieve protocol conversion.

[0074] 7. If the old protocol cannot be found in the map, give an alarm, indicating that the new protocol has changed and is not compatible with the old protocol.

[0075] The advantages of using the method of the present invention are as follows: 1. For the vehicle control protocol of a vehicle, there are at least one thousand and at most several thousand items. If all the old and new protocols are manually aligned, the workload is extremely huge. This method can quickly find the protocol alignment and save a lot of workload; 2. Different inspections are performed according to the necessity of the fields and the different types of the results of the field values, which can meet the use in various different situations; 3. Monitor whether the new protocol changes at one time, reducing the development difficulty of the new protocol.
