[0066] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0067] At present, the vehicle control service module in the vehicle receives the vehicle function setting instructions sent by the application interaction module, distributes the vehicle function setting instructions downward through the system basic module to realize the control of the vehicle; and receives the setting response data sent by the system basic module, and feeds back the setting response data upward so that the application interaction module can update the display interface.

[0068] However, after research, it was found that the communication interface between the application interaction module and the vehicle control service module is deeply bound to the vehicle function. The communication interface is not flexible enough, which is not conducive to the expansion of vehicle functions. The communication interface between the vehicle control service module and the system basic module is deeply bound to the system platform. The communication interface cannot be flexibly applied, which is not conducive to the transplantation of the system platform.

[0069] In order to solve this problem, in an embodiment of the present application, a first target request carrying a target vehicle function identifier sent by an application interaction module is received through a first universal interface; the target vehicle function identifier is converted into a target system function identifier according to a mapping relationship between multiple preset vehicle function identifiers and multiple preset system function identifiers; a second target request carrying a target system function identifier corresponding to the first target request is sent to a system basic module; the first response data carrying a target system function identifier returned by the system basic module for the second target request is received; according to the mapping relationship, the target system function identifier is converted into a target vehicle function identifier; the second response data carrying a target vehicle function identifier corresponding to the first response data is sent to the application interaction module through a second universal interface to update the display interface of the application interaction module. It can be seen that the method sets a first universal interface, a second universal interface, etc. to improve the versatility and flexibility of the communication interface between the application interaction module and the vehicle control service module, and improve the extensibility of the vehicle function; and sets a mapping relationship between multiple preset vehicle function identifiers and multiple preset system function identifiers, releases the deep binding of the communication interface between the vehicle control service module and the system basic module and the system platform, and improves the portability of the system platform.

[0070] For example, one of the scenarios of the embodiments of the present application can be seen in Figure 1 , Figure 1 This is a schematic diagram of the system framework involved in an application scenario in an embodiment of the present application. The scenario includes an application interaction module 101, a vehicle control service module 102, a system basic module 103 and a microcontroller unit (MCU) module 104. Among them, the mapping relationship between the multiple preset system function identifiers stored in the system basic module 103 and the multiple preset control signal identifiers stored in the MCU module 104 is used to construct a mapping relationship between multiple preset vehicle function identifiers and multiple preset system function identifiers.

[0071] First, in the above application scenario, the action description of the implementation method provided in the embodiment of the present application is executed by the vehicle control service module 102; however, the embodiment of the present application is not limited in terms of the execution subject, as long as the actions disclosed in the implementation method provided in the embodiment of the present application are executed.

[0072] Secondly, the above scenario is only an example scenario provided by the embodiment of the present application, and the embodiment of the present application is not limited to this scenario.

[0073] The specific implementation of the communication method and related devices of the vehicle control service module in the vehicle in the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0074] First, a specific implementation method of the communication method of the vehicle control service module in the vehicle in the embodiment of the present application is described in detail through an embodiment.

[0075] See also Figure 2 , shows a flow chart of a communication method of a vehicle control service module in a vehicle in an embodiment of the present application. In this embodiment, the method may include the following steps:

[0076] S201: Receive a first target request carrying a target vehicle function identifier sent by an application interaction module through a first universal interface.

[0077] At present, the communication interface between the application interaction module and the vehicle control service module in vehicles is deeply bound to the vehicle functions, which is not flexible enough and is not conducive to the expansion of vehicle functions. The communication interface between the vehicle control service module and the system basic module is deeply bound to the system platform, which is not flexibly applicable and is not conducive to the transplantation of the system platform.

[0078] Therefore, in the embodiment of the present application, a first universal interface, a second universal interface, etc. are set between the application interaction module and the vehicle control service module to improve the universality and flexibility of the communication interface between the application interaction module and the vehicle control service module, thereby improving the scalability of vehicle functions; and a mapping relationship between multiple preset vehicle function identifiers and multiple preset system function identifiers is set to release the deep binding of the communication interface between the vehicle control service module and the system basic module and the system platform, thereby improving the portability of the system platform. Based on this, the application interaction module sends a first target request to the vehicle control service module through the first universal interface, and the first target request needs to carry the target vehicle function identifier among the multiple preset vehicle function identifiers; then the vehicle control service module receives the first target request carrying the target vehicle function identifier sent by the application interaction module through the first universal interface.

[0079] S202: Converting a target vehicle function identifier into a target system function identifier according to a mapping relationship between a plurality of preset vehicle function identifiers and a plurality of preset system function identifiers.

[0080] In an embodiment of the present application, after executing S201, the vehicle control service module receives the first target request carrying the target vehicle function identifier sent by the application interaction module, considering that when the vehicle control service module communicates with the system basic module, the system basic module can only recognize the preset system function identifier; therefore, the vehicle control service module needs to convert the target vehicle function identifier into a preset system function identifier corresponding to the target vehicle function identifier in the multiple preset vehicle function identifiers, that is, the target system function identifier, according to the mapping relationship between the multiple preset vehicle function identifiers and the multiple preset system function identifiers.

[0081] S203: Sending a second target request carrying a target system function identifier corresponding to the first target request to the system basic module.

[0082] In an embodiment of the present application, after executing S202, the vehicle control service module converts the target vehicle function identifier into the target system function identifier, the vehicle control service module can convert the first target request carrying the target vehicle function identifier into a second target request carrying the target system function identifier, and the first target request corresponds to the second target request; then the vehicle control service module sends the second target request to the system basic module.

[0083] S204: Receive first response data carrying the target system function identifier returned by the system basic module in response to the second target request.

[0084] In an embodiment of the present application, after executing S203, the vehicle control service module sends a second target request carrying the target system function identifier to the system basic module, the system basic module responds to the second target request, obtains first response data carrying the target system function identifier, and returns it to the vehicle control service module; the vehicle control service module receives the first response data carrying the target system function identifier returned by the system basic module.

[0085] S205: Convert the target system function identifier into a target vehicle function identifier according to the mapping relationship.

[0086] In an embodiment of the present application, after executing S203, the vehicle control service module receives the first response data carrying the target system function identifier returned by the system basic module, considering that when the vehicle control service module communicates with the application interaction module, the application interaction module can only recognize the preset vehicle function identifier; therefore, the vehicle control service module needs to convert the target system function identifier into a preset vehicle function identifier corresponding to the target system function identifier in the multiple preset system function identifiers, that is, the target vehicle function identifier, according to the mapping relationship between the multiple preset vehicle function identifiers and the multiple preset system function identifiers.

[0087] As an example, see Figure 3 , Figure 3 A schematic diagram of converting a target vehicle function identifier into a target system function identifier and a target system function identifier into a target vehicle function identifier provided in an embodiment of the present application; wherein, the target vehicle function identifier is VehiclePropertyID, and the target system function identifier is CarPropertyID, then VehiclePropertyID can be converted to CarPropertyID through the mapping relationship between multiple preset vehicle function identifiers and multiple preset system function identifiers, and CarPropertyID can be converted to VehiclePropertyID through the mapping relationship between multiple preset vehicle function identifiers and multiple preset system function identifiers.

[0088] S206: Sending second response data carrying the target vehicle function identifier corresponding to the first response data to the application interaction module through the second universal interface; the second response data is used to update the display interface of the application interaction module.

[0089] In an embodiment of the present application, after executing S205 the vehicle control service module converts the target system function identifier into the target vehicle function identifier, the vehicle control service module can convert the first response data carrying the target system function identifier into second response data carrying the target vehicle function identifier, and the second response data corresponds to the first response data; then the vehicle control service module sends the second response data to the application interaction module through the second universal interface, so that the application interaction module updates the display interface of the application interaction module according to the second response data carrying the target vehicle function identifier.

[0090] Through the various implementation methods provided in this embodiment, a first target request carrying a target vehicle function identifier is received by an application interaction module through a first universal interface; the target vehicle function identifier is converted into a target system function identifier according to a mapping relationship between multiple preset vehicle function identifiers and multiple preset system function identifiers; a second target request carrying a target system function identifier corresponding to the first target request is sent to a system basic module; first response data carrying a target system function identifier is received and returned by the system basic module for the second target request; according to the mapping relationship, the target system function identifier is converted into a target vehicle function identifier; and second response data carrying a target vehicle function identifier corresponding to the first response data is sent to the application interaction module through a second universal interface to update the display interface of the application interaction module.

[0091] It can be seen that the method sets the first general interface, the second general interface, etc. to improve the universality and flexibility of the communication interface between the application interaction module and the vehicle control service module, and improve the scalability of the vehicle functions; and sets a mapping relationship between multiple preset vehicle function identifiers and multiple preset system function identifiers to release the deep binding of the communication interface between the vehicle control service module and the system basic module and the system platform, thereby improving the portability of the system platform.

[0092] In an embodiment of the present application, in order to convert the target vehicle function identifier into the target system function identifier according to the mapping relationship between multiple preset vehicle function identifiers and multiple preset system function identifiers when executing S201, first, it is necessary to obtain multiple preset vehicle function identifiers and multiple preset system function identifiers, and determine the mapping relationship between multiple preset vehicle function identifiers and multiple preset system function identifiers; then, initialize the vehicle control service module to read the mapping relationship between multiple preset vehicle function identifiers and multiple preset system function identifiers, and save the mapping relationship in the vehicle control service module. Therefore, in an optional implementation of the embodiment of the present application, the preprocessing step of the mapping relationship includes the following S1-S5:

[0093] S1: Acquire multiple preset vehicle function identifiers and multiple preset system function identifiers.

[0094] Among them, in an optional implementation of the embodiment of the present application, the preset vehicle function identifier needs to identify the function of the controller in the control domain of the vehicle. Therefore, the preset vehicle function identifier needs to include the vehicle's control domain identifier, controller identifier and function identifier.

[0095] As an example, the preset vehicle function identifier (VehiclePropertyID) is represented by a hexadecimal number, consisting of 4 bytes. Each byte is assigned a value in combination with the vehicle's overall electrical architecture. Byte 1 (Byte1) represents the control domain, and each control domain is sorted backward from 01, such as 01 corresponds to the entertainment control domain, 02 corresponds to the intelligent driving control domain, and so on; Byte 2 (Byte2) represents the controller, and within each control domain, each controller is sorted backward from 01, such as within the entertainment control domain, 01 corresponds to the air-conditioning controller, 02 corresponds to the front entertainment controller, and so on; Byte 3 and Byte 4 (Byte3Byte4) represent functions, and within each control domain, each function of each controller is sorted backward from 01, such as for the air-conditioning controller in the entertainment control domain, 0001 corresponds to the on / off function, and so on; based on this, the air-conditioning on / off function identifier of the air-conditioning controller in the entertainment control domain in the preset vehicle function identifier is 0x01010001.

[0096] Specifically, the preset vehicle function identifier (VehiclePropertyID) is shown in Table 1 below:

[0097] Table 1 VehiclePropertyID

[0098]

[0099] S2: Determine a mapping relationship between a plurality of preset vehicle function identifiers and a plurality of preset system function identifiers.

[0100] Based on the above Table 1, the mapping relationship between multiple preset vehicle function identifiers (VehiclePropertyID) and multiple preset system function identifiers (CarPropertyID) is shown in the following Table 2:

[0101] Table 2 Mapping relationship between multiple VehiclePropertyIDs and multiple CarPropertyIDs

[0102] VehiclePropertyID CarPropertyID DataType Alias 0x02010001 356***315 INT32 Alias1 0x02010002 356***316 FLOAT Alias2 0x02010003 356***317 FLOAT Alias3 0x02010004 356***318 INT32 Alias4 0x02010005 356***319 INT32 Alias5 0x02010006 356***320 INT32 Alias6 0x02010007 356***321 INT32 Alias7 … … … …

[0103] S3: Initialize the vehicle control service module.

[0104] S4: Read the mapping relationship.

[0105] S5: Save the mapping relationship in the vehicle control service module.

[0106] In an embodiment of the present application, in an optional implementation of an embodiment of the present application, the application interaction module can send a vehicle function setting instruction to the vehicle control service module, that is, the application interaction module can send a first setting request to the vehicle control service module through a universal setting interface, wherein the universal setting interface needs to include a vehicle function identifier, a numerical type, and a setting value; and receive the response data of the system basic module to the first setting request sent by the vehicle control service module through a universal callback interface, wherein the universal callback interface includes a callback state and a callback data encapsulation class composed of a vehicle function identifier, a numerical type, and a setting value. Based on this, the first target request is a first setting request, the first universal interface is a universal setting interface, the second target request is a second setting request, and the second universal interface is a universal callback interface.

[0107] As an example, the generic settings interface is represented as follows:

[0108] <e>void setProperty(Class <e>clazz,int propertyId,E value)

[0109] Among them, propertyId is the vehicle function identifier, clazz is the numeric type, and value is the set value.

[0110] The representation of the generic callback interface is as follows:

[0111] void onResponse(int errorCode,VehiclePropertyBean bean)

[0112] Among them, errorCode is the callback status, bean is the callback data encapsulation class, which consists of propertyId, clazz and value.

[0113] In an embodiment of the present application, in an optional implementation of the embodiment of the present application, the application interaction module can also send a function status acquisition instruction to the vehicle control service module, that is, the application interaction module can send a first acquisition request to the vehicle control service module through a universal acquisition interface, wherein the universal acquisition interface needs to include a vehicle function identifier and a numerical type; and receive the response data of the system basic module to the first acquisition request sent by the vehicle control service module through the universal acquisition interface. Based on this, when the first target request is the first acquisition request, the first universal interface is the universal acquisition interface, the second target request is the second acquisition request, and the second universal interface is the universal acquisition interface; the universal acquisition interface includes a vehicle function identifier and a numerical type.

[0114] As an example, the generic acquisition interface is represented as follows:

[0115] <e>E getProperty(Class <e>clazz,int propertyId)

[0116] Among them, propertyId is the vehicle function identifier, and clazz is a numeric type.

[0117] In summary, see Figure 4 , Figure 4 A specific flow chart of a communication method for a vehicle control service module in a vehicle provided in an embodiment of the present application; wherein, for the vehicle control service module, the vehicle control service module is initialized (init), the mapping relationship between multiple preset vehicle function identifiers and multiple preset system function identifiers is read (readIDs), and the mapping relationship is saved in the vehicle control service module (saveIDs). When the application interaction module sends a first setting request carrying a target vehicle function identifier (VehiclePropertyID) to the vehicle control service module through a universal setting interface to implement setting of a vehicle function (setVehicleProperty), after receiving the first setting request, the vehicle control service module converts the VehiclePropertyID into a target system function identifier (CarPropertyID) according to the mapping relationship between multiple preset vehicle function identifiers and multiple preset system function identifiers, i.e., VehiclePropertyIDToCarPropertyID; the vehicle control service module converts the first setting request carrying the VehiclePropertyID into a second setting request carrying the CarProperty, and sends the second setting request to the system base module to set the system function (setCarProperty). After the second setting request is made by the system basic module, a request response is made for the second setting request, and the first response data carrying CarProperty is obtained and returned to the vehicle control service module (onResponse); after the vehicle control service module receives the first response data carrying CarProperty returned by the system basic module, the vehicle control service module converts CarPropertyID into VehicleP ropertyID according to the mapping relationship between multiple preset vehicle function identifiers and multiple preset system function identifiers, that is, CarPropertyIDToVehiclePropertyID, and the vehicle control service module converts the first response data carrying CarPropertyID into the second response data carrying VehiclePropertyID, and sends the second response data to the application interaction module (onResponse). The vehicle control service module sends the second response data to the application interaction module through the general callback interface, so that the application interaction module updates the display interface of the application interaction module according to the second response data carrying VehiclePropertyID, that is, refreshUI.

[0118] When the application interaction module sends a first acquisition request carrying the target vehicle function identifier (VehiclePropertyID) to the vehicle control service module through the general acquisition interface to obtain the vehicle function status (getVehicleProperty), after receiving the first acquisition request, the vehicle control service module converts the VehiclePropertyID into CarPropertyID according to the mapping relationship between multiple preset vehicle function identifiers and multiple preset system function identifiers, that is, VehiclePropertyIDToCarPropertyID; the vehicle control service module converts the first acquisition request carrying VehiclePropertyID into a second acquisition request carrying CarProperty, and sends the second acquisition request to the system basic module to obtain the system function status (getCarProperty). After the system basic module obtains the second request, it responds to the second setting request, obtains the first response data carrying CarProperty, and returns it to the vehicle control service module (return); after the vehicle control service module receives the first response data carrying CarProperty returned by the system basic module, it converts CarPropertyID to VehiclePropertyID according to the mapping relationship between multiple preset vehicle function identifiers and multiple preset system function identifiers, that is, CarPropertyIDToVehiclePropertyID, and the vehicle control service module converts the first response data carrying CarPropertyID to the second response data carrying VehiclePropertyID, and sends the second response data to the application interaction module (return). The vehicle control service module sends the second response data to the application interaction module through the general callback interface, so that the application interaction module updates the display interface of the application interaction module according to the second response data carrying VehiclePropertyID, that is, refreshUI.

[0119] In addition, in the embodiment of the present application, in order to make it unnecessary to modify the communication code of the vehicle control service module in the vehicle when adding new vehicle functions in the future, thereby reducing the development workload, on the basis of the versatility and flexibility of the communication interface between the application interaction module and the vehicle control service module, the newly added vehicle function identifier can be directly obtained as the newly added vehicle function identifier, and the newly added vehicle function identifier corresponding to the preset system function identifier can be determined. By adding the newly added vehicle function identifier and the newly added vehicle function identifier corresponding to the preset system function identifier, the mapping relationship saved by the vehicle control service module can be updated, and the newly added vehicle function can be realized, thereby further improving the scalability of the vehicle function. Therefore, in an optional implementation of the embodiment of the present application, the method also includes the following S6-S8:
