[0002] In existing technologies, vehicle systems require many buses, among which CAN bus is short for Controller Area Network (CAN) bus. CAN messages are data packets transmitted on the CAN bus.

[0053] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0054] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

Any embodiment or design described as "exemplary" or "for example" in embodiments of the present invention should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner. Furthermore, in the description of embodiments of the present invention, unless otherwise stated, "a plurality of" means two or more.
[0056] It should be noted that, in this document, the term "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0057] The relevant terms in the embodiments of the present invention will be explained below.
[0058] CAN bus: A common communication bus in the automotive industry used to connect various electronic devices in a vehicle.
[0059] CAN message: A data packet transmitted on the CAN bus.
[0060] CAN signals: The specific content contained in a CAN message. A CAN message contains multiple CAN signals.
[0061] Based on the above, this invention provides an information processing method, referring to... Figure 1 As shown, the information processing method includes the following steps S101-S104:
[0062] S101. Obtain the message to be parsed from the bus.
[0063] Automobiles use many common buses to connect various electronic devices, and these buses carry numerous data packets called messages. Real-time detection is used to acquire and parse the messages on the bus when a message is detected.
[0064] S102. Determine the bus signals contained in the message to be parsed and the bus signals called by various service applications.
[0065] Step S102 above (determining the bus signals contained in the message to be parsed and the bus signals called by each service application) includes the following steps a and b:
[0066] Step a: Determine the bus signals contained in the message to be parsed.
[0067] In one optional implementation, the bus signal contained in the message to be parsed is looked up from the message-signal correspondence table in the database according to the message identifier of the message to be parsed.
[0068] The message-signal correspondence table contains all the bus signals contained in each message, as shown in Table 1 below.
[0069] Table 1
[0070] Message ID Bus signal 1 Bus signal 2 Bus signal 3 A have have none B have none have C have none none … … … …
[0071] As can be seen from the contents of the message-signal correspondence table, by looking up the message ID of the message to be parsed A in the message-signal correspondence table, we can find that the message to be parsed A contains two bus signals, namely bus signal 1 and bus signal 2.
[0072] Step b: Determine the bus signals for each service call.
[0073] In one alternative implementation, the bus signals called by each business application can be obtained by analyzing the bus signal calls of each business application. For example, if the business system has a total of 3 business applications, where business application 1 calls bus signal 1, business application 2 calls bus signal 3, and business application 3 calls bus signal 1, analysis shows that bus signal 1 and bus signal 3 were called by the business applications, while bus signal 2 was not called by the business applications.
[0074] S103. Based on the bus signals contained in the message to be parsed and the bus signals called by each service application, determine whether at least one service application has called at least one bus signal in the message to be parsed.
[0075] In step S103 (determining whether at least one service application has called at least one bus signal in the message to be parsed based on the bus signals contained in the message to be parsed and the bus signals called by each service application), if at least one service application calls at least one bus signal in the message to be parsed, it can be determined that a signal has been called in the message to be parsed, and it can be determined that the message to be parsed is used by an application, i.e., step S104 is executed. If none of the service applications call the bus signals in the message to be parsed, it can be determined that no signal has been called in the message to be parsed, and it can be determined that the message to be parsed is not used by an application, i.e., step S105 is executed.
[0076] In an optional embodiment, as shown in Table 1 above, there are three bus signals in the message A to be parsed: bus signal 1, bus signal 2, and bus signal 3. There are two service applications, service application 1 and service application 2. It is known that service application 1 calls bus signal 1 and service application 2 calls bus signal 3. Therefore, it can be concluded that bus signal 1 and bus signal 3 in the message A to be parsed are called by the service applications. That is, in the message A to be parsed, at least one bus signal is called by at least one service application. Then, step S104 is executed to parse the message to be parsed.
[0077] In an optional embodiment, as shown in Table 1 above, there are three bus signals in the message A to be parsed: bus signal 1, bus signal 2, and bus signal 3. There are two service applications, service application 1 and service application 2. It is known that service application 1 calls bus signal 4, and service application 2 calls bus signal 5. Therefore, it can be concluded that none of the bus signals in the message A to be parsed have been called by the service applications. In other words, none of the bus signals in the message A to be parsed have been called by the service applications. Therefore, step S105 is executed, and the message to be parsed is not parsed.
[0078] S104. The message to be parsed is parsed.
[0079] As an optional implementation, the message to be parsed is parsed by a parsing service to obtain the bus signals in the message to be parsed.
[0080] S105. Terminate the parsing of the message to be parsed.
[0081] The information processing method provided in this embodiment of the invention specifically involves: acquiring a message to be parsed from a bus; determining the bus signals contained in the message to be parsed and the bus signals invoked by various service applications; parsing the message if at least one service application invokes at least one bus signal in the message to be parsed; and terminating the parsing of the message if none of the service applications invoke the bus signals in the message to be parsed. Because the information processing method provided in this embodiment of the invention can determine whether the message needs to be parsed by first acquiring the message to be parsed on the bus, determining the bus signals contained in the message to be parsed and the bus signals invoked by various services, and determining whether at least one service application invokes at least one bus signal in the message to be parsed, the method parses the message when at least one service application invokes at least one bus signal in the message to be parsed, and terminates the parsing of the message when none of the service applications invoke the bus signals in the message to be parsed. This saves computing and storage resources by not parsing the message when none of the service applications invoke the bus signals in the message to be parsed.
[0082] As an extension and refinement of the above embodiments, this invention provides another information processing method, referred to... Figure 2 As shown, after step S104 is executed, the information processing method provided in this embodiment of the invention further includes the following steps:
[0083] S201. Obtain the interface type corresponding to each bus signal in the message to be parsed.
[0084] The interface type corresponding to any bus signal includes the interface type configured for that bus signal by each business application.
[0085] For example: When business application A and business application B are bus signal 1, the interface type configured is the first interface type; when business application C is bus signal 1, the interface type configured is the third interface type; and other business applications are all configured with the interface type for bus signal 1. Therefore, the interface types corresponding to bus signal 1 include the first interface type and the third interface type.
[0086] In one alternative implementation, the service application can configure four types of interface for the bus signal: a first interface type, a second interface type, a third interface type, and a fourth interface type.
[0087] The first interface type is used to indicate that the parsed data obtained from parsing the corresponding bus signal is distributed to the corresponding business application; the second interface type is used to indicate that the parsed data obtained from parsing the corresponding bus signal is cached in a preset cache space; the third interface type is used to indicate that the parsed data obtained from parsing the corresponding bus signal is stopped from being distributed to the corresponding business application; and the fourth interface type is used to indicate that the parsed data obtained from parsing the corresponding bus signal is stopped from being cached in a preset cache space.
[0088] For example, the first interface type can be a submit interface, which indicates that the signal is being listened to and its changes are being monitored throughout the entire time period. The signal needs to be continuously parsed and the parsed data returned to the business application. The second interface type can be a note interface, which is used to mark signals that the business application is interested in. After being marked, the parsing service needs to parse the signal and cache it after receiving the corresponding message so that it can be obtained in real time through the get interface. The third interface type can be an unsubmit interface, which indicates that the listening to the signal is ending. The fourth interface type can be an unnote interface, which indicates that the signal is being unmarked, indicating that the business application is not interested in the real-time nature of this signal.
[0089] S202. Based on the interface type corresponding to each bus signal in the message to be parsed, determine whether to parse each bus signal in the message to be parsed.
[0090] In an optional implementation, step S202 (determining whether to parse each bus signal in the message to be parsed based on the interface type corresponding to each bus signal in the message to be parsed) includes:
[0091] When the interface type corresponding to the first bus signal in the message to be parsed includes: a first interface type and / or a second interface type, the first bus signal is parsed.
[0092] When the interface type corresponding to the second bus signal in the message to be parsed only includes the third interface type and / or the fourth interface type, the second bus signal will not be parsed.
[0093] That is, the parsing priority of the first and second interface types is higher than that of the third and fourth interface types. When multiple interface types are included, the parsing requirements of the first and second interface types shall prevail.
[0094] For example, consider bus signal A and bus signal B, and service application 1 and service application 2. Service application 1 configures the interface type for bus signal A as the first interface type, and service application 2 configures the interface type for bus signal A as the third interface type. Service application 1 does not configure an interface type for bus signal B, and service application 2 configures the interface type for bus signal B as the third interface type. Since the corresponding interface type for bus signal A includes the first interface type, it is determined that bus signal A will be parsed. The corresponding interface type for bus signal B only includes the third interface type, therefore bus signal B will not be parsed.
[0095] In step S202 above, if it is determined that the bus signal needs to be parsed based on the interface type corresponding to a certain bus signal in the message to be parsed, then step S203 is executed; if it is determined that the bus signal does not need to be parsed based on the interface type corresponding to a certain bus signal in the message to be parsed, then step S204 is executed.
[0096] S203. Analyze the bus signals.
[0097] S204, No bus signal parsing is performed.
[0098] The information processing method provided in this embodiment of the invention, after parsing the message to be parsed, obtains the interface type corresponding to each bus signal in the message to be parsed, and determines whether to parse each bus signal in the message to be parsed based on the interface type of the bus signal. That is, when the interface type of the bus signal includes: a first interface type and / or a second interface type, the bus signal is parsed; when the interface type of the bus signal only includes: a third interface type and / or a fourth interface type, the bus signal is not parsed. Therefore, the information processing method provided in this embodiment of the invention further judges the bus signals, and only parses the bus signals that need to be parsed, and does not parse the bus signals that do not need to be parsed, thereby further saving computing resources and storage space.
[0099] As an extension and refinement of the above embodiments, this invention provides another information processing method, referred to... Figure 3 As shown, after step S104 is executed, the information processing method provided in this embodiment of the invention further includes the following steps:
[0100] S301. Obtain the interface type corresponding to each bus signal in the message to be parsed.
[0101] The interface type corresponding to any bus signal includes the interface type configured for that bus signal by each business application.
[0102] When the interface type corresponding to the first bus signal includes the first interface type (submit interface), the following steps S302 and S303 are performed on the first bus signal. The first bus signal can be any bus signal in the message to be parsed.
[0103] S302. Analyze the first bus signal.
[0104] S303. Send the parsed data obtained from parsing the first bus signal to the service application that has configured the first interface type for the first bus signal.
[0105] For example, if business application A in the business system configures a first interface type (submit interface) for configuring a first bus signal, wherein the first bus signal is a GPS signal, and the parsed data obtained after parsing the GPS signal is location information, then the GPS signal is parsed and the location information obtained after parsing the GPS signal is sent to business application A so that business application A can obtain the location information.
[0106] When the interface type corresponding to the first bus signal includes the second interface type (note interface), the following steps S304 and S305 are performed on the first bus signal. The first bus signal can be any bus signal in the message to be parsed.
[0107] S304. Analyze the first bus signal.
[0108] S305. Cache the parsed data obtained from parsing the first bus signal into the preset cache space.
[0109] After the parsed data obtained from parsing the first bus signal is cached in the preset cache space, the method provided in this embodiment of the invention may further include the following steps S306 to S308.
[0110] S306. Receive the first request information sent by the first service application.
[0111] The first request information is used to request the real-time return of the parsed data obtained from parsing the first bus signal.
[0112] S307. Read the parsed data obtained from parsing the first bus signal from the preset cache space.
[0113] S308. Send the parsed data obtained from parsing the first bus signal to the first service application.
[0114] In some embodiments, a business application can request parsed data obtained from parsing the first bus signal via the get interface to send the first request information. The get interface is an interface for real-time signal acquisition. The parsed data of a bus signal requested via the get interface needs to be marked in advance via the note interface so that when requesting the parsed data of this signal, the pre-parsed and cached parsed data of the bus signal can be quickly obtained.
[0115] For example, if a business application B needs to call the parsed data of the first bus signal through the get interface, it can first mark the first bus signal through the note interface so that the first bus signal can be parsed and the parsed data can be cached in the preset cache space. When the business application B requests the parsed data of the first bus signal through the get interface, the parsed data of the first bus signal is directly read from the preset cache space and returned to the business application B.
[0116] When the interface type corresponding to the second bus signal includes only the third interface type (unsubmit interface) and / or the fourth interface type (unnote interface), the following step S309 is performed on the second bus signal.
[0117] The second bus signal can be any bus signal in the message to be parsed. The interface type corresponding to the second bus signal includes only the third interface type and / or the fourth interface type, which can also be understood as the interface type corresponding to the second bus signal not including the first interface type or the second interface type.
[0118] S309, Do not parse the second bus signal.
[0119] After step S309, the method provided in this embodiment of the invention may further include the following steps S310 to S312:
[0120] S310, Receive the second request information sent by the second service application.
[0121] The second request information is used to request the return of the parsed data obtained by parsing the second bus signal.
[0122] S311. Analyze the second bus signal.
[0123] S312. Send the parsed data obtained from parsing the second bus signal to the second service application.
[0124] In some embodiments, a business application can use the get_wait interface to request parsed data obtained from parsing the second bus signal in order to send the second request information. The get_wait interface is a non-real-time signal acquisition interface; it does not require pre-marking of signals, but only waits to acquire the signal message and parses the returned result upon invocation.
[0125] For example, if a business application C needs to call the parsed data of the second bus signal through the get_wait interface, since the get_wait interface does not mark the second bus signal in advance, the second bus signal has not been parsed when the call is made. Therefore, when the call for parsing the second bus signal through the get_wait interface is received, the second bus signal needs to be parsed and the parsed data obtained from parsing the second bus signal needs to be sent to the business application C.
[0126] In one optional implementation, if it is determined that the bus signal does not need to be parsed, the bus signal is discarded, and after receiving the second request, the application waits for the next bus signal with the same name. For example, when a bus signal A is received for the first time, if the application does not need this bus signal, it discards the bus signal A to avoid wasting storage resources. After receiving the second request, the application waits for the next bus signal A. When the bus signal A is obtained again, it is parsed to obtain parsed data, and the parsed data obtained from parsing the bus signal A is sent to the application.
[0127] In one optional implementation, when it is determined that the bus signal does not need to be parsed, the bus signal is stored in a preset database. When a second request is received, the bus signal is retrieved from the preset database and parsed. For example, when a bus signal A is received for the first time, if the application does not need this bus signal, bus signal A is stored in the preset database. When the second request is received, bus signal A is retrieved from the preset database, parsed to obtain parsed data, and then the parsed data obtained from parsing bus signal A is sent to the application.
[0128] Based on the same inventive concept, as an implementation of the above method, this embodiment of the invention also provides an information processing device. This embodiment corresponds to the aforementioned method embodiment. For ease of reading, this embodiment will not repeat the details of the aforementioned method embodiment one by one, but it should be clear that the information processing device in this embodiment can implement all the contents of the aforementioned method embodiment.
