In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0063] With the development of economy and technology, the performance of automobile computers has been continuously improved, and the software functions on the car have become more and more complicated. The communication data between the bottom control end (Microcontroller Unit, MCU) and the upper operating system (Operating System, OS) of the automobile computer has also increased dramatically.

[0064] For the communication between the bottom control end and the upper operating system of the car, the commonly used communication method is to integrate the instrument communication data and the central control communication data transmitted from the MCU end to the upper operating system end into a single communication channel for processing. This communication method not only affects the processing rate of the communication data, but also increases the load rate of the concurrent processing of the OS system end, and increases the risk of confusion in the transmission of instrument data and central control data during the communication process, which is an error that is extremely difficult to find during code execution.

[0065] Based on the above considerations, an embodiment of the present invention provides an automobile business layer communication method, which can improve the data processing efficiency of the vehicle computer bottom control end and the upper operating system end, reduce the load rate of the OS system end during concurrent processing, and improve the problem of data transmission disorder. The method is introduced below.

[0066] The automobile service layer communication method provided by the embodiment of the present invention can be applied to Figure 1 In the shown automobile business layer communication system 100, the automobile business layer communication system 100 includes a vehicle controller 110, a SOC end 120, an on-board instrument 130 and a central control device 140. The SOC end 120 is connected to multiple peripheral storage chips 121. The first communication interface of the controller 110 is respectively connected to the second communication interface of each peripheral storage chip 121. The SOC end 120 can be respectively communicated with the on-board instrument 130 and the central control device 140 in a wired or wireless manner.

[0067] The controller 110 is connected to the vehicle's underlying hardware devices 150 and the monitoring device 160 of the underlying hardware devices 150 through the CAN bus.

[0068] It should be understood that a communication channel is formed between the second communication interface of each peripheral storage chip 121 and the first communication interface of the controller 110 .

[0069] The underlying hardware devices 150 include but are not limited to: an engine, an electric motor, an oil / electricity monitoring device 160, a brake device, a transmission, an onboard air conditioner and a handle, etc.

[0070] Taking the setting of two peripheral memory chips 121 as an example, the connection method between the controller 110, the peripheral memory chip 121 and the SOC terminal 120 can be as follows: Figure 2 As shown, two peripheral memory chips 121 are used as slaves of the controller 110 and are both connected to the SOC terminal 120 .

[0071] After determining the communication protocol between the controller 110 and the SOC end 120 , each protocol message under the communication protocol can be matched with each channel according to the function or data structure, the matching relationship can be recorded in a matching table, and the matching table can be stored.

[0072] It should be noted that the controller 110 and each peripheral memory chip 121 of the SOC end 120 transmit communication data using the Serial Peripheral Interface (SPI) communication protocol to achieve SPI communication with one master and multiple slaves (the controller 110 is the master and the peripheral memory chip 121 is the slave). The SOC end 120 and the central control device 140 and the vehicle instrument 130 use a transparent transmission method to transmit communication data, and the SOC end 120 runs the vehicle computer operating system.

[0073] In a possible implementation manner, an embodiment of the present invention provides an automobile service layer communication method, referring to Figure 3 , may include the following steps. In this embodiment, the automobile service layer communication method is applied to Figure 1 The controller 110 in FIG. 1 is used as an example.

[0074] S11, receiving any processing request through the first communication interface.

[0075] In this embodiment, after receiving the processing request from the vehicle instrument 130 or the central control device 140 , the SOC end 120 sends the processing request through the second communication interface of the peripheral storage chip 121 matching the processing request.

[0076] S13, obtaining a processing result in response to the processing request, classifying the processing request, and generating response data of the processing request according to the processing result and the classification result.

[0077] S15, determining a target chip from a plurality of peripheral storage chips according to the classification result.

[0078] S17, sending the response data to the SOC end through the target chip, so that the SOC end displays the response data on the function interface of the central control device or the vehicle instrument.

[0079] The processing requests include but are not limited to: motor start request, vehicle speed query request, air conditioner on request, air conditioner off request, fuel / electricity acquisition request and driving data request.

[0080] The vehicle instrument 130 or the central control device 140 transparently transmits the processing request to the SOC end 120, and the SOC end 120 classifies the processing request and sends the processing request to the peripheral storage chip 121 matching the classification result according to the classification result. Each peripheral storage chip 121 caches the received processing request in the message queue, scans the message queue regularly, and sends the processing request with the highest order in the message queue to the first communication interface of the controller 110.

[0081] After the controller 110 receives the processing request from its first communication interface, it performs logic processing in response to the processing request to obtain the processing result. For example, if it is a vehicle speed query request, the controller 110 obtains the current speed from the motor monitoring device 160 and obtains the current vehicle speed based on the current speed. In addition, the processing request is classified to obtain the classification result, so that the controller 110 generates response data based on the classification result and the processing result. Furthermore, a target chip matching the classification result is determined from multiple peripheral storage chips 121, and the response data is sent to the target chip from the first communication interface.

[0082] After the SOC end 120 obtains the response data through the target chip, it transparently transmits the response data to the central control device 140 or the vehicle instrument 130 that sends the processing request.

[0083] Compared with the traditional communication method in which all communication data are concentrated into one communication channel to communicate between the controller and the SOC end, in the automobile business layer communication method provided by the embodiment of the present invention, multiple communication channels are established between the SOC end of the vehicle and the controller through multiple peripheral storage chips, so that processing requests and response data of different classification results are transmitted through the communication channel matching the classification result, that is, sent and received by the peripheral storage chip matching the classification result, thereby realizing classified transmission of communication data, which can reduce the confusion of data transmission and, at the same time, realize concurrent processing of multiple communication channels to improve data processing efficiency.

[0084] In addition, since data transmission is shared among various peripheral memory chips on the SOC side, the load rate on the SOC side can be greatly reduced.

[0085] Depending on the processing request, the method of obtaining the processing result in response to the processing request can be flexibly set. For example, data can be obtained from the underlying hardware device 150, or it can be processed according to preset rules. In this embodiment, no specific limitation is made.

[0086] In one possible implementation, refer to Figure 4 , the processing results can be obtained through the following steps.

[0087] S131, obtaining operation data reported by the underlying hardware device and / or monitoring device corresponding to the processing request.

[0088] S132, processing the run data to obtain a processing result.

[0089] The operation data may be the operation data (e.g., fuel / electricity and speed) reported by the underlying hardware device 150 and / or the monitoring device 160 before receiving the processing request, or the operation data returned after the execution command is sent to the underlying hardware device 150 and / or the monitoring device 160 after receiving the processing request. For example, if the processing request is an air-conditioning start-up request, a start-up command is sent to the vehicle air-conditioning, and the vehicle air-conditioning turns on the air-conditioning, switches the model, and sets the temperature, and then returns an ok command to the controller 110. After receiving the ok command, the controller 110 obtains the processing result.

[0090] Furthermore, the method for classifying processing requests can also be flexibly set. For example, they can be classified according to preset rules, or they can be classified using a neural network algorithm. In this embodiment, no specific limitation is made.

[0091] In order to quickly classify processing requests, refer to Figure 5 The automobile service layer communication method provided by the embodiment of the present invention may also include the following steps.

[0092] S21, obtaining a protocol table file, and reading text content of the protocol table file.

[0093] The protocol table file is a table file of the communication protocol used for communication between the SOC terminal 120 and the controller 110, and records the structure information of each protocol instruction / protocol message of the protocol. For example, if the communication protocol is the SPI protocol, the protocol table file records the structure information of each protocol instruction / protocol message of the SPI protocol. The structure information includes the structure definition.

[0094] It should be understood that the text content includes the structure definition of each protocol message of the communication protocol between the SOC terminal 120 and the controller 110 .

[0095] S22, generating a data structure for each protocol message according to the structure definition.

[0096] S23, classify and store each data structure according to the preset keyword classification rules.

[0097] The keyword classification rules include but are not limited to: classification based on senders and receivers as keywords, and classification based on functions as keywords.

[0098] It should be understood that the essence of the data structure is a data packet encoding assistance program, that is, a program for generating data packets.

[0099] Since the sender and receiver of the communication data (i.e., the initiator and the receiver) are the vehicle-mounted instrument 130 or the central control device 140, all communication data can be divided into instrument data (Cluster) or central control data (HU). According to the different functions and display methods, the communication data can also be divided into icon display data and soft switch button status display data.

[0100] Therefore, each data structure can be classified and stored according to function and display, or can be classified and stored according to sender and receiver.

[0101] For example, after reading the text content, before step S22, the sender and receiver can be used as keywords for classification and classification processing. For example, if it is the warning and indication information of the vehicle instrument 130, it can be classified into an item named "MCU_cluster warning and indicator INFO"; if it is the status acquisition information of the underlying hardware device 150 of the central control device 140, it can be classified into an item named "MCU_HU can 0x20B INFO", which can be as shown in Table 1.

[0102] Table 1

[0103]

[0104]

[0105] In step S22, for each protocol instruction / protocol message that has been classified, a corresponding data structure is generated according to its own structure definition. In a possible implementation, it can be a C language data structure.

[0106] In step S23, based on the classified projects, create .c project files and .h project files of the data packet encoding helper corresponding to the projects, for example, they may include MCU_Cluster_PacketCodecHelper.h project file, MCU_Cluster_PacketCodecHelper.c project file, MCU_HU_PacketCodecHelper.h project file, MCU_HU_PacketCodecHelper.c project file, and store the data structure of each protocol instruction / protocol message in the corresponding project file.

[0107] When the communication protocol adopted by the controller 110 and the SOC end 120 is changed, the protocol format file in step S21 is replaced with the protocol format file of the new communication protocol.

[0108] The above steps S21-S22 are the pre-steps of the automatic classification algorithm, and can also be understood as the acquisition steps of the automatic classification algorithm.

[0109] On the basis of the above, an automatic classification algorithm may be used to classify the processing requests. Specifically, it may be further implemented as follows: parsing the processing requests to obtain request keywords, and determining the data structure of the processing requests according to the request keywords.

[0110] The request keyword may be a characteristic part of a structure for processing a request.

[0111] After the data structure of the processing request is determined, the sender and receiver can be determined according to the project file where the data structure is located.

[0112] For a processing request, the structure of the corresponding response message has the same parts as its own structure. Therefore, after obtaining the request keyword of the processing request, the controller 110 can determine the data structure that matches the request keyword from all stored data structures based on the request keyword, and determine the sender and receiver based on the project file where the data structure is located.

[0113] After the data structure of the processing request is determined, the response data of the processing request can be generated in the following manner: according to the logical processing result, the value of the result field in the data structure is updated to obtain the response data.

[0114] In a possible implementation, the controller 110 may pre-store a matching table, which records the matching relationship between each data structure and each communication channel. Step S15 may be further implemented as: querying the matching table, determining the communication channel that matches the data structure of the processing request, and using the external storage chip 121 corresponding to the communication channel as the target chip.

[0115] Through the above steps S21-S23, and the implementations of S13 and S15, the processing requests can be quickly and accurately classified, the corresponding response data can be generated, and the target chip matching the response data can be determined, which can avoid data streaming to a certain extent.

[0116] In order to avoid data streaming, in a possible implementation, the sender's identifier is added to the response data, so that after the SOC end 120 obtains the response data, it can send the response data to the device corresponding to the identifier according to the identifier on the response data.

[0117] In a possible implementation manner, the embodiment of the present invention further provides an automobile service layer communication method, referring to Figure 6 , may include the following steps. In this embodiment, the automobile service layer communication method is applied to Figure 1 Take the SOC end 120 in FIG. 1 as an example.

[0118] S31, receiving a processing request sent by an on-board instrument or a central control device.

[0119] S32, determining a communication channel that matches the processing request, and taking the peripheral storage chip corresponding to the communication channel as the target chip.

[0120] S33, sending the processing request to the controller through the second interface of the target chip.

[0121] The controller implements the automobile business layer communication method provided above, that is, the controller uses the above steps S11-S17 to send the response data of the processing request to the target chip, and the target chip sends the response data to the SOC end.

[0122] S34, receiving the response data returned by the controller through the target chip, and reporting the response data to the target device for display on the function interface of the target device, wherein the target device is the vehicle instrument or central control device that sends the processing request.

[0123] In one possible implementation, refer to Figure 7 , the communication channel that matches the processing request can be determined through the following steps.

[0124] S321, parsing the processing request to obtain a request keyword, and determining a data structure of the processing request according to the request keyword.

[0125] S322, query a preset matching table to determine a communication channel that matches the data structure of the processing request.

[0126] For further implementation of S321, reference may be made to the automobile business layer communication method applied to the controller provided above, which will not be described in detail in this implementation.

[0127] In the above-mentioned automobile business layer communication method, when the SOC receives a processing request from the central control device or the vehicle instrument, it sends the processing request to the matching communication channel for processing according to the matching result of the request keyword, which can reduce the probability of data streaming. And through multiple peripheral storage chips, multi-concurrent communication can be achieved to improve the transmission efficiency of communication data. In addition, there is no need for the SOC to process the sending process, which can greatly reduce the load rate of the SOC.

[0128] In a possible implementation manner, the present invention further provides an automobile service layer communication device 170, which can be applied to Figure 1 The controller 110 in FIG. Figure 8 The automobile business layer communication device 170 may include a receiving module 180 , a processing module 190 and a sending module 200 .

[0129] The receiving module 180 is used to receive any processing request through the first communication interface. After receiving the processing request from the vehicle instrument or the central control device, the SOC sends the processing request through the second communication interface of the peripheral storage chip matching the processing request.

[0130] The processing module 190 is used to obtain a processing result in response to the processing request, classify the processing request, and generate response data of the processing request according to the processing result and the classification result.

[0131] The processing module 190 is further configured to determine a target chip from a plurality of peripheral storage chips according to the classification result.

[0132] The sending module 200 is also used to send the response data to the SOC end through the target chip, so that the SOC end displays the response data on the function interface of the central control device or the vehicle instrument.

[0133] In the above-mentioned automobile business layer communication device 170, through the coordinated action of the receiving module, the processing module and the sending module, multiple communication channels are established between the SOC end of the vehicle and the controller through multiple peripheral storage chips, so that the processing requests and response data of different classification results are transmitted through the communication channel matching the classification results, thereby realizing the classified transmission of communication data, which can reduce the confusion of data transmission, and at the same time, realize concurrent processing of multiple communication channels, which can improve data processing efficiency.
