DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0020] In the description of the present invention, reference to an "embodiment" means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the described embodiments may be combined with other embodiments.

[0021] Currently, vehicle-side data upload is mainly in the form of CAN data, and is generally uploaded as a real-time data stream.

[0022] However, the data transmission rate supported by the CAN bus is limited. In application scenarios with high requirements for transmission bandwidth, data transmission via the CAN bus will be difficult to meet data transmission requirements.

[0023] Ethernet provides a higher data transmission rate and can meet application scenarios with high requirements for transmission bandwidth. However, when vehicle-side data is currently uploaded via Ethernet, it is also uploaded in the form of real-time data streams, which easily causes a waste of bandwidth resources and affects the user experience of other vehicle functions.

[0024] In order to solve the above problems, the present invention provides a vehicle data uploading method based on vehicle Ethernet.

[0025] The specific embodiments are described in detail below: A specific embodiment of the present invention discloses a vehicle data uploading method based on vehicle Ethernet, combined with Figure 1 Come and see, Figure 1 The flowchart of an embodiment of a vehicle data uploading method based on vehicle Ethernet provided by the present invention includes steps S101 to S103, wherein: In step S101, real-time vehicle data and the current vehicle data uploading mode are obtained; In step S102, when the current vehicle data uploading mode is the real-time mode, the real-time vehicle data is uploaded based on a first preset period; In step S103, when the current vehicle data upload mode is the event mode, the vehicle data to be uploaded is determined based on the target upload trigger event and uploaded.

[0026] During implementation, the telematics box (TBOX) on the vehicle can first obtain real-time vehicle data from the autonomous driving electronic control unit (ADECU) and / or microprocessor unit (MPU), such as the vehicle's real-time operating parameters, video information around the vehicle, etc.

[0027] Then you can also obtain the current vehicle data upload mode. The vehicle data upload mode can be issued by the data demand platform, which mainly includes real-time mode and event mode. In real-time mode, the platform has a higher demand for vehicle data, which is generally used in vehicle testing before leaving the factory; in event mode, the platform only needs to obtain vehicle data before and after certain specific events, such as vehicle failure events, which is generally used during the normal operation of the vehicle.

[0028] When the current vehicle data upload mode is real-time mode, TBOX can upload real-time vehicle data to the data demand platform according to the first preset period (for example, every 5 seconds); when the current vehicle data upload mode is event mode, TBOX can determine the vehicle data to be uploaded and upload it according to the target upload trigger event. The target upload trigger event can be a vehicle failure event, an abnormal driving event, etc.

[0029] The vehicle data uploading method based on vehicle Ethernet provided by the present invention can be applied to the pre-delivery test scenario of commercial vehicles, and can also be applied to the operation monitoring scenario of commercial vehicles, and the present invention does not make specific limitations on this.

[0030] Compared with the prior art, the vehicle data uploading method based on vehicle Ethernet provided in this embodiment first obtains real-time vehicle data and a vehicle data uploading mode, then confirms the current data uploading demand according to the vehicle data uploading mode, and then adopts the corresponding data uploading method according to the current data uploading demand. When there is no need to upload vehicle data in real time, data uploading is triggered by a target trigger event, thereby reducing the bandwidth resources occupied by vehicle data uploading and improving the user experience of other vehicle functions. The present invention can adjust the vehicle data uploading method according to the current data uploading demand, reducing the bandwidth resources occupied by vehicle data uploading and improving the user experience of other vehicle functions.

[0031] Exemplarily, the method further includes: When the current vehicle data upload mode is the event mode, the acquired real-time vehicle data is stored in a packet cache queue, each network packet in the real-time vehicle data corresponds to an index number, and the index numbers corresponding to each network packet are arranged consecutively according to the receiving time; The target index number is recorded based on a second preset period, where the target index number is the index number corresponding to the network packet whose receiving time is closest to the current moment.

[0032] Specifically, when the current vehicle data upload mode is the event mode, TBOX can first store the acquired real-time vehicle data in the packet cache queue. In addition, each network packet in the real-time vehicle data corresponds to an index number, and the index numbers corresponding to each network packet are arranged continuously according to the receiving time. TBOX can record the index number (i.e., the target index number) corresponding to the network packet whose receiving time is closest to the current time according to the second preset period (e.g., every 1s or every 0.5s), thereby providing a basis for the subsequent determination of the vehicle data to be uploaded.

[0033] Exemplarily, determining the vehicle data to be uploaded based on the target upload triggering event includes: Determining the vehicle data to be uploaded based on the target index number at the triggering time of the target upload triggering event, the target index number at the first time, and the triggering time of the second upload triggering event; The first moment is the moment that is a first time length before the target moment, the second upload trigger event is the upload trigger event whose trigger time is closest to the second moment, the second moment is the moment that is a first time length after the target moment, and the target moment is the trigger time of the target upload trigger event.

[0034] Specifically, when determining the vehicle data to be uploaded according to the target upload trigger event, the vehicle data to be uploaded can be determined according to the target index number of the triggering moment (i.e., the target moment) of the target upload trigger event, the target index number of the moment (i.e., the first moment) of the first time length (e.g., 10s) before the target moment, and the triggering moment of the second upload trigger event, thereby ensuring that the vehicle data related to the target upload trigger event can be uploaded. The second upload trigger event is the upload trigger event whose triggering moment is closest to the moment (i.e., the second moment) of the first time length (e.g., 10s) after the target moment.

[0035] Exemplarily, determining the vehicle data to be uploaded based on the target index number at the triggering time of the target upload triggering event, the target index number at the first time, and the triggering time of the second upload triggering event includes: In the case where the second upload triggering event is the target upload triggering event, a network packet having an index number between the target index number at the first moment and the target index number at a third moment is determined as the vehicle data to be uploaded, and the third moment is a moment at a second time length after the target moment; In the case that the second upload trigger event is not the target upload trigger event, the network packet whose index number is between the target index number at the first moment and the target index number at the fourth moment is determined as the vehicle data to be uploaded, and the fourth moment is the moment at the second time length after the triggering moment of the second upload trigger event.

[0036] Specifically, after the target upload trigger event is triggered, there may be other related upload trigger events, or there may not be other upload trigger events. Therefore, it is necessary to determine the vehicle data to be uploaded according to the actual situation.

[0037] When the second upload trigger event is a target upload trigger event, the network packet with an index number between the target index number at the first moment and the target index number at the moment (i.e., the third moment) at a second time length (e.g., 5s) after the target moment can be determined as the vehicle data to be uploaded.

[0038] When the second upload trigger event is not a target upload trigger event, the network packets with index numbers between the target index number at the first moment and the target index number at the fourth moment can be determined as the vehicle data to be uploaded, and the fourth moment is the moment at which the second time length (e.g., 5s) is located after the triggering moment of the second upload trigger event. That is, at most, the vehicle data within the first time length + the second time length after the target moment needs to be uploaded. For example, if the first time length is set to 10s and the second time length is set to 5s, then at most, the vehicle data within 15s after the target moment needs to be uploaded.

[0039] Exemplarily, the method further includes: Before uploading the real-time vehicle data or the vehicle data to be uploaded, the real-time vehicle data or the vehicle data to be uploaded are spliced ​​into JSON data.

[0040] Specifically, in order to facilitate the transmission of vehicle data, before uploading the real-time vehicle data or the vehicle data to be uploaded, TBOX can splice the real-time vehicle data or the vehicle data to be uploaded into JavaScript Object Notation (JSON) data and then upload it.

[0041] Exemplarily, the splicing of the real-time vehicle data or the vehicle data to be uploaded into JSON data includes: The real-time vehicle data or the vehicle data to be uploaded are spliced ​​into JSON data based on the identity information of TBOX and the current timestamp information.

[0042] Specifically, when TBOX splices real-time vehicle data or vehicle data to be uploaded into JSON data, it can also splice its own identity (such as vid, tboxid, simid, etc.) and current timestamp information into the JSON data.

[0043] Exemplarily, in a possible implementation, the acquiring real-time vehicle data includes: Monitor the multicast address of ADECU and / or MPU to obtain the real-time vehicle data.

[0044] Specifically, when acquiring real-time vehicle data, TBOX may acquire real-time vehicle data by monitoring the multicast address of ADECU and / or MPU.

[0045] The technical solution of the present invention is better described below with reference to a specific embodiment: The vehicle data upload solution provided by the present invention mainly involves TBOX, ADECU / MPU, front-view integrated machine and surround-view controller, combined with Figure 2 Come and see, Figure 2 This is a flow chart of an embodiment of a vehicle data uploading process provided by the present invention, and the process includes the following steps: When the data upload mode is "real-time mode", the ADECU / MPU sends real-time Ethernet data, and TBOX transmits it to the platform for analysis.

[0046] When the data upload mode is "Event Mode", TBOX rolls and caches Ethernet event data, determines whether to upload the cached data based on the event ID, and captures the first 10s and last 5s of data for upload based on the event occurrence time. When multiple events are continuous or the interval is less than 15s, data is continuously uploaded to the last 5s of the last event.

[0047] The TBOX implementation involves three threads: the packet receiving thread, the event mode packet sending thread, and the real-time mode packet sending thread.

[0048] 1. Packet receiving thread.

[0049] The packet receiving operation mainly monitors the multicast addresses of ADECU and MPU and receives network packets from the bottom layer, so the packet receiving operation is the same in both modes. The difference is that after receiving the network packet, the event mode will store the packet, and when an event occurs, the event mode packet sending thread will extract the network packet at the corresponding time point from the cache area, process it into compressed json data, and then send it out; while the real-time mode will process the packet into json data and cache it after receiving it, and when it exceeds 5s, it will wake up the real-time mode packet sending thread to compress the json data in the cache area and send it out.

[0050] 2. Network packet processing flow.

[0051] The two modes process network packets in the same way after receiving them. The process is mainly divided into the following steps: a. Parse network packets.

[0052] The network packet may be multiple packets or single packets, and needs to be processed after parsing according to the protocol header. If it is a single packet, go directly to the next step; if it is multiple packets, you need to assemble them into a complete packet before going to the next step.

[0053] b. Assemble json object data.

[0054] After taking out the valid data of a single network packet or an assembled multi-packet complete network packet, it is spliced ​​with TBOX's vid, tboxid, simid, timestamp and other information to form a json data and temporarily stored in a buffer.

[0055] c. Send data Event Mode: Gzip the JSON data 10s before and 5s (or ≤15s) after the event is triggered, and send it to the platform using HTTP file transfer.

[0056] Live Mode: Every 5 seconds, the data in the JSON data buffer will be gzip compressed and sent to the platform using HTTP file transfer.

[0057] 3. Event mode packet sending thread In event mode, the packet receiving thread will store the received network packets in the packet cache queue. Each network packet will correspond to an index number, and a network packet counter cache queue will record the current packet index number every 1 second to trace which network packet corresponds to the 10 seconds before the trigger event. When an event occurs, the trigger time is recorded, and the index number of the corresponding packet 10 seconds ago is found from the network packet counter cache queue based on the trigger time. Then, based on the index number 10 seconds ago and the index number at the current moment, the 10 seconds of data is taken out from the packet cache queue, and the data is processed and sent to the platform. The remaining 5s (or ≤15s) data has not been cached yet, so it needs to wait for 5s (<=15s) and be sent after unified processing. In the case of ≤15s, if multiple events are generated continuously within 10s after the trigger time, in order to reduce the upload of duplicate data, the data between the trigger time of the last event and the 10s before the first trigger time will be sent, as well as the data 5s after the trigger time of the last event, so there will be data 15s after the trigger at most.

[0058] The present invention can meet different data acquisition requirements while ensuring vehicle driving safety.
