[0002] In the automotive AUTOSAR (AUTomotive Open System Architecture) architecture, the amount of computing power of the on-board controller is growing exponentially. The occupation of the computing core power by the on-board network communication has become a problem that cannot be ignored.

[0025] 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 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.

[0026] According to the AUTOSAR architecture, the path for messages from the physical layer to the application layer is: from the bus driver module to the bus interface module, then to other AUTOSAR basic software modules, then to the RTE (Runtime environment) interface, and finally to the application layer.

[0027] Among them, the bus driver module is used to identify the specified bus frame and convert the electrical signal into a digital signal; the bus interface module is used to isolate the other layers of the basic software from the driver layer and receive the physical signals transmitted by the driver layer; the RTE interface is used for the virtual data bus to isolate the basic software from the application layer; the application layer is used to process the message and implement corresponding strategies.

[0028] Figure 1 It is a flow chart of a vehicle network communication event filtering method provided by an embodiment of the present invention. The embodiment of the present invention can be applied to the scenario of filtering vehicle network communication messages. The method can be executed by a vehicle network communication event filtering device, which can be implemented by software and / or hardware.

[0029] like Figure 1 As shown, the vehicle network communication event filtering method includes the following steps:

[0030] S110: Obtain a message to be processed sent by any communication bus, and identify a message filtering category corresponding to the message to be processed.

[0031] Among them, the communication bus is used to transmit the pending messages sent by the physical layer. The pending messages represent each message that originally needs to be sent from the physical layer to the application layer, and are messages that have not been judged whether they need to be filtered. The pending messages can represent vehicle network communication events; the pending messages include CAN (Controller Area Network) messages, LIN (Local Interconnect Network) messages, and ETH (Ethernet) messages. The message filtering category represents the filtering category corresponding to the pending message. The message filtering category includes filtering category and non-filtering category. The pending messages belonging to the filtering category need to be filtered, and the pending messages belonging to the non-filtering category do not need to be filtered. Specifically, the data in the pending message can be identified to determine the preset message type corresponding to the pending message, and the message filtering category corresponding to the pending message can be determined.

[0032] Specifically, Figure 2 is a structural diagram of a vehicle network communication message transmission device provided by an embodiment of the present invention, such as Figure 2 As shown, the vehicle network communication message transmission device includes an EDF (Event-Driven Filter) module, a CANIF (Controller Area Network Interface) module, an ETHIF (Ethernet Interface) module, and a LINIF (Local Interconnect Network Interface) module. Among them, the CANIF module is used to transmit CAN messages, the ETHIF module is used to transmit ETH messages, the LINIF module is used to transmit LIN messages, and the EDF module is used to filter CAN messages, ETH messages, and LIN messages.

[0033] S120: When the message filtering category is a message category to be filtered, match the message to be processed with a target message filtering policy.

[0034] Among them, the message filtering category includes the non-filtered message category and the to-be-filtered message category. The to-be-processed messages of the non-filtered message category do not need to be filtered, and the to-be-processed messages of the to-be-filtered message category need to be further determined to determine whether they need to be filtered. The target message filtering policy indicates that when the message filtering category of the to-be-processed message is the to-be-filtered message category, the message filtering policy corresponding to the to-be-processed message can be further determined through the target message filtering policy whether the to-be-processed message needs to be filtered.

[0035] S130: Filter the to-be-processed message according to the target message filtering policy.

[0036] Among them, it can be judged whether the message to be processed meets the message filtering condition in the target message filtering policy. If the target message filtering policy is met, there is no need to filter the message to be processed. If the message filtering condition is not met, the message to be processed needs to be filtered. For example, when the message to be processed represents the collected driving mileage, the message filtering condition in the target message filtering policy can be set to: whether the difference between the driving mileage collected this time and the mileage collected last time is greater than 0.1 kilometers. If the difference between the driving mileage collected this time and the mileage collected last time is greater than 0.1 kilometers, then there is no need to filter the message to be processed. If the difference between the driving mileage collected this time and the mileage collected last time is not greater than 0.1 kilometers, then there is no need to filter the message to be processed.

[0037] The technical solution provided by the embodiment of the present invention obtains the pending message sent by any communication bus and identifies the message filtering category corresponding to the pending message; when the message filtering category is the message category to be filtered, the pending message is matched with the target message filtering strategy; according to the target message filtering strategy, the pending message is filtered. The technical solution of the embodiment of the present invention solves the problems in the prior art that the network communication message has a high load on the controller computing core, the filtering effect of the network communication message is insufficient, and there is compatibility with the vehicle communication architecture. The network communication message can be selectively filtered according to the configured filtering strategy, thereby reducing the load of the network communication message on the controller computing core, improving the real-time performance of the controller in processing events and the safety of vehicle driving.

[0038] Figure 3 It is a flow chart of a vehicle network communication event filtering method provided by an embodiment of the present invention. The embodiment of the present invention can be applied to the scenario of filtering vehicle network communication messages. Based on the above embodiment, this embodiment further illustrates how to identify the message filtering category corresponding to the message to be processed and filter the message to be processed. The device can be implemented by software and / or hardware and integrated in a computer device with application development function.

[0039] like Figure 3 As shown, the vehicle network communication event filtering method includes the following steps:

[0040] S210: Obtain a message to be processed sent by any communication bus, and determine a message filtering category corresponding to the message to be processed according to an event type corresponding to the message to be processed.

[0041] Among them, the message to be processed refers to the message that has not been judged whether it needs to be filtered. The message to be processed can represent an in-vehicle network communication event. The messages to be processed include CAN messages, LIN messages and ETH messages. The event type indicates the type of in-vehicle network communication event corresponding to the message to be processed. The event types include oil temperature report events, door status report events, mileage data report events and remaining fuel report events. The event type can be preset according to filtering needs. The message filtering category indicates the filtering category corresponding to the message to be processed. Different message filtering categories correspond to different filtering strategies. Specifically, the event type corresponding to the message to be processed can be determined by identifying the data in the message to be processed, and then the message filtering category corresponding to the message to be processed can be determined.

[0042] S220. According to the same corresponding event type, match the corresponding event message filtering policy for the message to be processed as the target message filtering policy.

[0043] Among them, the event message filtering policy represents the strategy for filtering the messages to be processed. The event type corresponds to the corresponding event message filtering policy. The event type corresponding to the message to be processed can be used to match the event message filtering policy corresponding to the event type, and then the event message filtering policy corresponding to the message to be processed can be determined and used as the target message filtering policy for the message to be processed.

[0044] Specifically, Table 1 is a vehicle network communication event filtering strategy table provided by an embodiment of the present invention.

[0045] Table 1

[0046]

[0047]

[0048] As shown in Table 1, the event type of the message can be determined according to the meaning of the message, and then the filtering strategy of the message can be determined. "Always update" means that the message does not need to be filtered, and "event driven" means that when the message meets the "update condition event", it does not need to be filtered, otherwise it needs to be filtered.

[0049] Among them, the filtering strategy for vehicle speed message, air bag status message and brake command message is always updated without filtering; the filtering strategy for oil temperature message is event-driven, and the update condition event of the message is: the data collected by the bus differs from the data analyzed last time by more than 1 degree Celsius; the filtering strategy for door status message is event-driven, and the update condition event of the message is: there is a difference between the data collected by the bus and the data analyzed last time; the filtering strategy for mileage message is event-driven, and the update condition event of the message is: the data collected by the bus differs from the data analyzed last time by more than 0.1 kilometers; the filtering strategy for remaining fuel message is event-driven, and the update condition event of the message is: update every 10 seconds.

[0050] S230: Compare the target message data in the message to be processed with the reference message data obtained by parsing the message of the same event type last time.

[0051] Among them, the target message data represents the data that needs to be analyzed in the message to be processed, and the reference message data represents the data in the message with the same event type as the message to be processed that was parsed last time. According to the target message filtering strategy, based on the comparison result of the target message data in the message to be processed and the reference message data obtained from the previous parsing of the message with the same event type, it can be determined whether the message to be processed needs to be filtered.

[0052] S240: When the difference between the target message data and the reference message data is less than a preset value, filter the message to be processed.

[0053] Among them, the preset value represents a preset value determined according to the target message filtering strategy. When the difference between the target message data and the reference message data is less than the preset value, it indicates that the message to be processed is a repeated and redundant message, and the message to be processed is filtered. When the difference between the target message data and the reference message data is greater than the preset value, the message to be processed is not filtered. For example, when the message to be processed is an oil temperature report message, 1 degree Celsius can be set as the preset value to determine whether the difference between the oil temperature value in the message to be processed and the oil temperature value in the last oil temperature report message is less than 1 degree Celsius. When the difference between the oil temperature value in the message to be processed and the oil temperature value in the last oil temperature report message is less than 1 degree Celsius, the message to be processed is filtered; when the difference between the oil temperature value in the message to be processed and the oil temperature value in the last oil temperature report message is greater than 1 degree Celsius, the message to be processed is not filtered.

[0054] In an optional implementation, the time of the message to be processed can also be obtained to determine the time interval of the message with the same event type as the message to be processed in the previous analysis; when the time interval is less than the preset time threshold, the message to be processed is filtered. Different judgment strategies can be set according to different message contents.

[0055] Among them, when the time interval is less than the preset time threshold, it means that the message to be processed is a repeated and redundant message, and the message to be processed is filtered; when the time interval is greater than the preset time threshold, the message to be processed is not filtered. For example, when the message to be processed is a remaining fuel report message, 10 seconds can be set as the preset time threshold to determine whether the time interval between the message to be processed and the last received remaining fuel report message is greater than 10 seconds. When the time interval is less than 10 seconds, the remaining fuel report message is filtered; when the time interval is greater than 10 seconds, the remaining fuel report message is not filtered.

[0056] In an optional implementation, when the message filtering category is a non-filtering message category, the message to be processed is sent to the target application interface.

[0057] Among them, the event types of messages corresponding to the non-filtered message category include vehicle speed reporting events, airbag status reporting events and brake command reporting events. The target application interface is used to receive unfiltered pending messages and send unfiltered pending messages to the application layer for further processing.

[0058] Specifically, Figure 4 is a vehicle network communication message filtering flow chart provided by an embodiment of the present invention, such as Figure 4 As shown, the message is sent by the bus driver module to the bus interface module, that is, the EDF module. When the vehicle speed message is identified, the update condition is directly met and released to other modules, and the data is passed to APP (APPLICATION) for processing and corresponding strategies; when the oil temperature message is identified, it is determined whether the update condition is met. If the update condition is met, it is released to other modules and the data is passed to APP for processing and corresponding strategies; when the remaining fuel message is identified, it is determined whether the update condition is met. If it does not meet the update condition, the remaining fuel message is filtered, and the data of the remaining fuel message is not passed to the upper layer, and other processes are executed next.

[0059] The technical solution provided by the embodiment of the present invention obtains the message to be processed sent by any communication bus, and determines the message filtering category corresponding to the message to be processed according to the event type corresponding to the message to be processed; matches the corresponding event message filtering strategy for the message to be processed according to the event type corresponding to the message to be processed as the target message filtering strategy; compares the target message data in the message to be processed with the reference message data obtained from the previous analysis of the message of the same event type; when the difference between the target message data and the reference message data is less than a preset value, the message to be processed is filtered. The technical solution of the embodiment of the present invention solves the problems in the prior art that the network communication message has a high load on the controller computing core, the filtering effect of the network communication message is insufficient, and there is compatibility with the vehicle communication architecture. The network communication message can be selectively filtered according to the configured filtering strategy to reduce the load of the network communication message on the controller computing core, improve the real-time performance of the controller in processing events and the safety of vehicle driving.

[0061] like Figure 5 As shown, the vehicle network communication event filtering device includes: a message filtering category determination module 310, a message filtering strategy matching module 320 and a message filtering processing module 330.

[0062] The message filtering category determination module 310 is used to obtain a message to be processed sent by any communication bus and identify a message filtering category corresponding to the message to be processed;

[0063] The message filtering policy matching module 320 is used to match the target message filtering policy for the message to be processed when the message filtering category is the message category to be filtered;

[0064] The message filtering processing module 330 is used to filter the messages to be processed according to the target message filtering policy.

[0065] The technical solution provided by the embodiment of the present invention obtains the pending message sent by any communication bus and identifies the message filtering category corresponding to the pending message; when the message filtering category is the message category to be filtered, the pending message is matched with the target message filtering strategy; according to the target message filtering strategy, the pending message is filtered. The technical solution of the embodiment of the present invention solves the problems in the prior art that the network communication message has a high load on the controller computing core, the filtering effect of the network communication message is insufficient, and there is compatibility with the vehicle communication architecture. The network communication message can be selectively filtered according to the configured filtering strategy, thereby reducing the load of the network communication message on the controller computing core, improving the real-time performance of the controller in processing events and the safety of vehicle driving.

[0066] In an optional implementation, the message filtering category determination module 310 is specifically used to determine the message filtering category corresponding to the message to be processed according to the event type corresponding to the message to be processed, wherein different event types correspond to different message filtering categories.

[0067] In an optional implementation, the message filtering policy matching module 320 is specifically used to: match the message to be processed with the corresponding event message filtering policy as the target message filtering policy according to the event type corresponding to the message to be processed.

[0068] In an optional implementation, the message filtering policy matching module 320 is specifically used to: compare the target message data in the message to be processed with the reference message data obtained by parsing the message of the same event type last time;

[0069] When the difference between the target message data and the reference message data is less than a preset value, the message to be processed is filtered.

[0070] In an optional implementation, the message filtering policy matching module 320 is further used to: determine the time interval of the message with the same event type as the message to be processed as parsed last time according to the time when the message to be processed is acquired;

[0071] When the time interval is less than the preset time threshold, the message to be processed is filtered.

[0072] In an optional implementation, the vehicle network communication event filtering device further includes a non-filtered message uploading module, which is used to send the message to be processed to the target application interface when the message filtering category is a non-filtered message category;

[0073] Among them, the event types of the messages corresponding to the non-filtered message category include vehicle speed report events, airbag status report events and brake command report events.

[0074] In an optional implementation, the event type includes: one or more of an oil temperature reporting event, a vehicle door status reporting event, a mileage data reporting event, and a remaining fuel reporting event.
