[0055] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0056] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0057] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0058] The main solution of the embodiment of the present application is: to deduplicate the original CAN message of the target vehicle to obtain the CAN message to be parsed; to determine the current startup task based on the priority of the signal acquisition task; to determine the target vehicle signal in the parsed vehicle signal corresponding to the CAN message to be parsed based on the rule information of the current startup task, and to collect the target vehicle signal; and to upload the signal data collected during the deduplication collection time period to the cloud.

[0059] At present, in the process of data transmission between the vehicle and the cloud, data deduplication operations usually use SQL to screen and process related data. Due to the complexity of writing SQL statements, deduplication is not considered comprehensively enough, and duplicate and redundant data will still exist. When processing this data, resource consumption will increase. Once multiple collection tasks are run, the vehicle is prone to enter a high-load state, affecting the data processing efficiency of the vehicle.

[0060] The present application provides a solution to deduplicate the received original CAN messages to avoid repeated parsing of the same data, and to deduplicate the time period of data collection before uploading the data. Only data within different time periods can be uploaded to avoid repeated uploading of data, reduce duplicate and redundant data, and reduce vehicle-side resource consumption. At the same time, priorities are set between tasks, and signals are collected according to the priorities to avoid the vehicle-side entering a high-load state, improve processing efficiency, and solve the technical problems of a large amount of duplicate and redundant data, increased resource consumption, and affecting the vehicle-side data processing efficiency.

[0061] It should be noted that the execution subject of this embodiment may be a vehicle-side data processing device capable of realizing the above functions, and this embodiment does not specifically limit this. The following takes the vehicle-side data processing device as an example to illustrate this embodiment and the following embodiments.

[0062] The present application embodiment provides a vehicle-side data processing method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle-side data processing method of the present application.

[0063] In this embodiment, the vehicle-side data processing method includes steps S10 to S40:

[0064] Step S10, deduplication of the original CAN message of the target vehicle is performed to obtain the CAN message to be parsed;

[0065] It should be noted that the target vehicle is the vehicle currently undergoing data processing. The original CAN (Controller Area Network) message, that is, the original CAN message received, is usually transmitted by the various components of the target vehicle to the vehicle-side data processing device of the target vehicle through the CAN bus. The original CAN message usually contains the data / information that the vehicle-side data processing device needs to obtain, such as: vehicle signals, which are not specifically limited. This embodiment is explained using vehicle signals as an example. Vehicle signals are related parameter information fed back by various components of the vehicle, such as: speed, battery status, door status, light status, etc., which are not specifically limited. After receiving the original CAN message, the vehicle-side data processing device parses it to obtain these vehicle signals.

[0066] In addition, it should be noted that after the vehicle signal is parsed, it is necessary to collect the signal according to the task issued by the cloud, and upload the corresponding signal data to the cloud. During the data transmission process between the vehicle side (the vehicle-side data processing device of the target vehicle) and the cloud, the data deduplication operation usually uses SQL to perform relevant data screening and processing, which cannot perform deduplication operations when receiving the original CAN message, which will lead to an increase in duplicate and redundant data, increase resource consumption, and the vehicle is prone to enter a high-load state, affecting the data processing efficiency of the vehicle side. Therefore, this embodiment performs data deduplication when receiving the original CAN message to reduce duplicate and redundant data, reduce resource consumption, and improve vehicle-side data processing efficiency.

[0067] It can be understood that the CAN message to be parsed is the CAN message obtained after deduplication.

[0068] In a feasible implementation manner, the step of deduplicating the original CAN message of the target vehicle may include steps S101 to S102:

[0069] Step S101, filtering out duplicate data frames in the original CAN message and deleting the duplicate data frames;

[0070] It should be noted that a duplicate data frame is a duplicate data frame in the original CAN message, that is, the same data frame in the original CAN message, and the duplicate data frame needs to be deleted to reduce data redundancy. Exemplarily, in the forwarded data message, the RX (Receive) data frame and the TX (Transmit) data frame are the same. If the original CAN message contains both the RX data frame and the TX data frame, it can be considered that the RX data frame is a duplicate data frame relative to the TX data frame, and the TX data frame is a duplicate data frame relative to the RX data frame. At this time, the TX data frame can be deleted as a duplicate data frame and the RX data frame can be retained, or the RX data frame can be deleted as a duplicate data frame and the TX data frame can be retained.

[0071] Step S102, based on the identification information and time sequence information of the original CAN message, determine the latest CAN message corresponding to the same identification information within a preset time period, and delete the original CAN messages except the latest CAN message.

[0072] It should be noted that different CAN messages are usually distinguished by identification information, which may be an ID (Identity Document), namely a CAN ID, which is not specifically limited. This embodiment uses a CAN ID as an example for illustration. The identification information of the original CAN message is the CAN ID of the original CAN message.

[0073] It is understandable that the vehicle-side data processing device may receive messages from the same CAN ID within a period of time. If each received message is parsed, unnecessary resource consumption will increase. Therefore, the latest message can be retained, and other messages can be deleted to deduplicate the data corresponding to the CAN ID.

[0074] In addition, it should be noted that the time sequence information is information that can indicate the time sequence of the original CAN message arrival, such as: timestamp, which is not specifically limited. The preset time period is the period set to retain the latest message, which is usually not too long and can ensure processing efficiency while deduplication, such as: 10ms, which is not specifically limited. The latest CAN message is the latest received / arrived original CAN message, and the latest CAN message corresponding to the same identification information within the preset time period is the latest original CAN message from the same CAN ID within the preset time period.

[0075] It should be understood that the latest original CAN message from the same CAN ID within the preset time period is retained, and the remaining original CAN messages are deleted. After deduplication of the data frames in the original CAN message and deduplication of the data corresponding to the CAN ID, the CAN message to be parsed can be obtained.

[0076] Step S20, determining the current startup task based on the priority of the signal acquisition task;

[0077] It should be noted that the signal acquisition task is a task issued by the cloud to collect the required signals. The signal acquisition task at least includes the basic information of the task and the initial startup state. The basic information of the task is the specific content of the signal acquisition task, including at least the accessed stream information and rule information. The accessed stream information is the stream accessed when collecting signals, and the rule information is the rules to be followed for collecting signals. The basic information of the task is usually in the form of SQL statements. For example, the basic information of the signal acquisition task A is: select a,b from 100ms_stream where c>0, that is, access data from the stream named 100ms_stream, and the collection rule is: when c>0, collect a signal and b signal. The initial startup state is whether the controller is started immediately when it receives the signal acquisition task. If so, the signal acquisition task needs to be started immediately. If not, the signal acquisition task is started later.

[0078] In addition, it should be noted that all received signal acquisition tasks will form a list, namely the task list, and the vehicle-side data processing device will mark the running status of each signal acquisition task in the task list. The running status of the signal acquisition task includes two states, the start state and the stop state (pause state). If the signal acquisition task is in the start state, it means that the signal acquisition task is running, and if the signal acquisition task is in the stop state, it means that the signal acquisition task is not running.

[0079] It is understandable that the vehicle-side data processing device will perform signal acquisition according to the signal acquisition task whose running state is the start state. The more signal acquisition tasks there are, the greater the resource consumption of the vehicle-side. It can be seen that in the case of data redundancy, once multiple acquisition tasks are run, the vehicle is prone to enter a high-load state, affecting the data processing efficiency of the vehicle-side, and also affecting the realization of the vehicle-side functions. Therefore, this embodiment sets corresponding priorities for all signal acquisition tasks, and decides which tasks are started or stopped according to the priorities of the signal acquisition tasks to avoid the vehicle-side from entering a high-load state.

[0080] It should be understood that the currently started task, i.e., the signal acquisition task that needs to be run currently, has been adjusted accordingly according to the priority of the signal acquisition task. The priority of the signal acquisition task can generally be divided into high priority, medium priority, and low priority, and the corresponding signal acquisition tasks are high priority tasks, medium priority tasks, and low priority tasks. Generally speaking, the tasks that need to be stopped will be decided in the low priority task / medium priority task, and the tasks that need to be started will be decided in the medium priority / high priority task.

[0081] Step S30, based on the rule information of the current startup task, determining the target vehicle signal in the parsed vehicle signal corresponding to the CAN message to be parsed, and collecting the target vehicle signal;

[0082] It should be noted that the target vehicle signal, i.e., the signal to be collected contained in the analyzed vehicle signal, can be determined according to the rule information of the current startup task. For example, assuming that the rule information of the current startup task B is: when c>0, collect a signal and b signal, then the signals to be collected by the current startup task B are a signal and b signal.

[0083] It can be understood that after the vehicle signal is analyzed and obtained, the target vehicle signal and the value of the target vehicle signal are collected.

[0084] Step S40, uploading the signal data collected during the deduplication collection time period to the cloud.

[0085] It should be noted that different collection rules may trigger repeated collection time periods (time periods for collecting target vehicle signals), and data in the same collection time period is usually stored in the same file. It can be seen that when uploading data to the cloud, it is very likely that the same data will be uploaded repeatedly. Figure 2 , rule1 and rule2 are collection rule 1 and collection rule 2 respectively. The collection time period triggered by collection rule 1 is [t0, t2], and the collection time period triggered by collection rule 2 is [t1, t3]. If the data collected at [t0, t2] and [t1, t3] are uploaded to the cloud, the data collected at [t1, t2] will be uploaded repeatedly. Therefore, it is necessary to deduplicate the collection time period.

[0086] In a feasible implementation, the step of determining a deduplicated collection time period may include: determining the collection time period of the target vehicle signal based on the rule information corresponding to the current startup task of the target vehicle signal; determining a repeated time period based on the collection time period of the target vehicle signal; and deleting the repeated time period in the collection time period to obtain the deduplicated collection time period.

[0087] It should be noted that the repeated time period is the time period in which repeated data are collected, and the deduplicated collection time period is the collection time period after deduplication. For example, Figure 2 In the figure, [t1, t2] is the repeated time period, and [t0, t2] and [t2, t3] are the deduplication collection time periods.

[0088] It can be understood that according to the rule information of the currently started task, the collection time period of each currently started task can be determined, so as to find the repeated time period, delete the repeated time period in the collection time period, and then determine the deduplication collection time period, and upload the cached files in the deduplication collection time period to the cloud.

[0089] This embodiment provides a vehicle-side data processing method, which deduplicates the original CAN message of the target vehicle to obtain the CAN message to be parsed; determines the current startup task based on the priority of the signal acquisition task; determines the target vehicle signal in the parsed vehicle signal corresponding to the CAN message to be parsed based on the rule information of the current startup task, and collects the target vehicle signal; uploads the signal data collected during the deduplication collection time period to the cloud. Deduplication is performed on the received original CAN message to avoid repeated parsing of the same data, and the time period of the collected data is deduplicated before uploading the data. Only data in different time periods is uploaded to avoid repeated uploading of data, reduce duplicate and redundant data, and reduce vehicle-side resource consumption. At the same time, priorities are set between tasks, and signal collection is performed according to the priority to avoid the vehicle-side entering a high-load state and improve processing efficiency.

[0090] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 3 , step S01 may be included before step S10:

[0091] Step S01, when the original CAN message of the target vehicle is received, based on the arrival order of the original CAN message, corresponding time sequence information is added to the original CAN message of the target vehicle.

[0092] It should be noted that the arrival order of the original CAN messages is the order in which the original CAN messages arrive at the vehicle-side data processing device. The time sequence information of the original CAN messages is set according to the arrival order of the original CAN messages.

[0093] In a feasible implementation, step S01 may include: when receiving the original CAN message of the target vehicle, based on the arrival order of the original CAN message, counting the original CAN message to obtain the counting sequence of the original CAN message; adding the counting sequence of the original CAN message as time sequence information to the corresponding original CAN message.

[0094] It should be noted that the network connection may be unstable during the driving process of the vehicle, especially in remote areas or places with weak network signals, which will affect the timing and integrity of data upload. Generally, a timestamp obtained by synchronization between the vehicle end and the background is added to the data. However, due to the existence of clock drift and network delay, this timestamp may have the problem of time inversion, resulting in the inaccuracy of the timestamp on the data. That is, when the vehicle end and the background perform time synchronization, the network delay may cause the transmission of time information to lag, so that the time sequence information received by the vehicle end is not the latest. Even if the vehicle end has synchronized the time, due to the existence of network delay, the time data actually used may still be old. Therefore, this embodiment counts according to the arrival order of the original CAN message, forms a corresponding counting sequence as time sequence information and adds it to the original CAN message to further ensure the accuracy of the time sequence information.

[0095] It is understandable that the counting sequence can adopt a self-increasing sequence. The self-increasing sequence is a sequence marked by a hardware counter. It does not rely on the accuracy of the machine's clock, but generates a sequence based on the relative time of each message arrival. This sequence can ensure the timing of the data, but the self-increasing sequence itself cannot reflect the true timeliness of the data. Every time a new CAN message is received, the self-increasing sequence is increased by "1". When the self-increasing sequence is full, it will go back and count again. When the CCM (Chassis Control Module) is powered on again and awakened from sleep, the self-increasing sequence will also count again. When the self-increasing sequence is full, it will start counting from the beginning. Therefore, when a large self-increasing sequence is followed by a small self-increasing sequence, it can be known that the counting has started again, that is, the subsequent data will arrive later.

[0096] Step S10 may include step S11:

[0097] Step S11, obtaining the timestamp information of the CAN message to be parsed, and adding the timestamp information into the corresponding CAN message to be parsed.

[0098] It can be understood that the timestamp information is the timestamp obtained by the synchronization background, and the corresponding timestamp information is added to the CAN message to be parsed. The data format of the final CAN message to be parsed can be referred to Figure 4 , based on the information it contains, it adds a self-increasing sequence and timestamp.

[0099] It should be understood that the timestamp obtained by the synchronization background plus the self-increasing sequence can effectively ensure the timing of receiving messages and will not cause incorrect time sequence information due to problems such as network delays.

[0100] This embodiment provides a vehicle-side data processing method, which adds a timestamp obtained by the synchronization background and a self-increment sequence marked by a hardware counter to the CAN message to ensure the timing of the received message, so that the latest CAN message can be accurately determined and the accuracy of deduplication can be guaranteed.

[0101] Based on the above embodiments of the present application, in the third embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above introduction, and will not be described in detail later. Figure 5 , step S20 may include steps S201 to S204:

[0102] Step S201, obtaining resource consumption data of the target vehicle, and judging whether the target vehicle is in a high-load state based on the resource consumption data;

[0103] It should be noted that the resource consumption data is data that can reflect the resource consumption of the target vehicle. If the resource consumption is high, it means that the target vehicle is in a high-load state. If the resource consumption is low, it means that the target vehicle is not in a high-load state.

[0104] Step S202, when the target vehicle is in a high-load state, determining a low-priority startup task based on the running state and priority of the signal acquisition task;

[0105] It should be noted that the priority of signal acquisition tasks can usually be divided into high priority, medium priority and low priority, and the corresponding signal acquisition tasks are high priority tasks, medium priority tasks and low priority tasks. The attributes of signal acquisition tasks at different levels are inconsistent. For example, high-level tasks: once triggered to run on the vehicle side, they are not allowed to be stopped; medium-level tasks: can be stopped and started on the vehicle side according to resource conditions; low-level tasks: once stopped due to priority management when running on the vehicle side, they are not allowed to be started again.

[0106] In addition, it should be noted that, in order to determine the priority between signal acquisition tasks of the same level, this embodiment sets a ranking value of 0-99, and the larger the ranking value, the lower the priority. Figure 6 Task 1, Task 2, and Task 3 are high-level tasks, Task 4, Task 5, and Task 6 are medium-level tasks, and Task 4, Task 5, and Task 6 have different ranking values ​​in the medium-level tasks, which are 3, 2, and 1 respectively. Task 7, Task 8, and Task 9 are low-level tasks, and Task 7, Task 8, and Task 9 have different ranking values ​​in the low-level tasks, which are 4, 3, and 2 respectively.

[0107] It is understandable that a low priority startup task is a signal acquisition task with a lower priority, a startup state, and can be stopped. In this embodiment, a high priority task cannot be stopped, so a medium-level task and a low-level task with a startup state can be used as a low priority startup task.

[0108] It should be understood that when the target vehicle is in a high-load state, it is necessary to reduce the running tasks and select low-priority startup tasks so as to subsequently determine the signal acquisition tasks that need to be stopped.

[0109] Step S203, based on the ranking value of the low-priority startup task, determining a target stop task in the low-priority startup task, and adjusting the running state of the target stop task to a stop state;

[0110] It should be noted that the target stop task is the signal acquisition task that needs to be stopped. According to the ranking value of the low priority start task, the lowest priority low priority start task is found as the target stop task, and the running state of the target stop task will be adjusted to the stop state.

[0111] It is understandable that if the target vehicle is still in a high-load state after stopping a task, a new target stop task can be determined from the remaining low-priority start tasks, and the running state of the new target stop task can be adjusted to the stop state, and so on, until there is no task to stop, or the target vehicle is no longer in a high-load state.

[0112] For example, reference Figure 6 , assuming that tasks 1 to 9 are all running, and the target vehicle is detected to be in a high-load state, the task process is triggered to stop. At this time, the tasks are sorted according to their priorities and sorting values, that is, task 1 = task 2 = task 3 > task 6 > task 5 > task 4 > task 9 > task 8 > task 7. Tasks 4 to 9 can be started as low-priority tasks, among which task 7 has the lowest priority, so task 7 is stopped first. According to the actual load situation, tasks 8, task 9, task 4, task 5, and task 6 can also be stopped in turn.

[0113] Step S204: taking the signal collection task whose running state is the startup state as the current startup task.

[0114] It can be understood that, after priority management, the signal acquisition task whose current running state is the startup state is the current startup task.

[0115] This embodiment provides a vehicle-side data processing method, which obtains the resource consumption data of the target vehicle, and determines whether the target vehicle is in a high-load state based on the resource consumption data; when the target vehicle is in a high-load state, based on the running state and priority of the signal acquisition task, a low-priority start task is determined; based on the ranking value of the low-priority start task, a target stop task is determined in the low-priority start task, and the running state of the target stop task is adjusted to the stop state; the signal acquisition task with the running state of the start state is used as the current start task. Priorities are set between tasks, and signals are collected according to the priorities. When the target vehicle is in a high-load state, some tasks with lower priorities are stopped to prevent the vehicle-side from entering a high-load state and improve processing efficiency.

[0116] Based on the above-mentioned embodiment 3 of the present application, in the fourth embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment can refer to the above introduction, and will not be repeated later. Figure 7 , step S201 may include steps S202' to S204':

[0117] Step S202', when the target vehicle is not in a high-load state and has abundant resources, a high-priority stop task is determined based on the running state and priority of the signal acquisition task;

[0118] It should be noted that a high priority stop task is a signal acquisition task with a higher priority, a running state of a stop state and can be started. In this embodiment, a high priority task cannot be stopped, and a low priority task cannot be started after being stopped. Therefore, a medium-level task with a running state of a stop state can be used as a high priority stop task.

[0119] It is understandable that when the target vehicle is not in a high-load state and has abundant resources, the running tasks can be increased and the high-priority stop tasks can be selected so as to subsequently determine the signal collection tasks that need to be started.

[0120] Step S203', based on the ranking value of the high priority stop task, determine the target start task in the high priority stop task, and adjust the running state of the target start task to the start state;

[0121] It should be noted that the target start task is the signal acquisition task that needs to be started. According to the ranking value of the high priority stop task, the high priority stop task with the highest priority is found as the target start task, and the running state of the target start task will be adjusted to the start state.

[0122] It is understandable that if the target vehicle still has surplus resources after starting a task, a new target start task can be determined from the remaining high-priority stop tasks, and the running state of the new target start task can be adjusted to the start state, and so on, until no tasks can be started or the target vehicle is close to a high load state.

[0123] For example, reference Figure 6 , assuming that there are tasks 1 to 9, and tasks 4 to 9 have been stopped due to resource shortage. At this time, it is detected that the target vehicle has abundant resources, which triggers the start of the task process. At this time, the stopped tasks are sorted according to the priority and sorting value of the tasks, that is, task 6>task 5>task 4>task 9>task 8>task 7. Tasks 4 to 6 can be used as high-priority stopped tasks, among which task 6 has the highest priority, so task 6 will be started first. According to the actual load situation, tasks 5 and 4 can also be started in sequence.

[0124] For example, reference Figure 6, assuming that there are tasks 1 to 9, and tasks 7 to 9 have been stopped due to resource shortage. At this time, it is detected that the target vehicle has abundant resources, which triggers the start of the task process. At this time, the stopped tasks are sorted according to the task priority and sorting value, that is, task 9>task 8>task 7. Since tasks 7 to 9 are all low-priority tasks, they cannot be started after being stopped. At this time, no task can be used as a high-priority stopped task, and thus no task can be started.

[0125] Step S204': taking the signal collection task whose running state is the startup state as the current startup task.

[0126] It can be understood that, after priority management, the signal acquisition task whose current running state is the startup state is the current startup task.

[0127] In the specific implementation, refer to Figure 8 When it is detected that the vehicle-side resources are tight, the vehicle-side triggers the task stop process, selects a signal acquisition task with the lowest priority from the running tasks, and executes the task pause operation; when the vehicle-side resources are abundant, selects a signal acquisition task with the highest priority from the tasks that have been stopped due to resource shortages, and executes the task start operation.

[0128] This embodiment provides a vehicle-side data processing method. When the target vehicle is not in a high-load state and resources are abundant, a high-priority stop task is determined based on the running state and priority of the signal acquisition task; based on the ranking value of the high-priority stop task, a target start task is determined in the high-priority stop task, and the running state of the target start task is adjusted to the start state; the signal acquisition task with the running state of the start state is used as the current start task. Priorities are set between tasks, and signals are collected according to the priorities. When the target vehicle is not in a high-load state, some tasks with higher priorities are started to avoid wasting vehicle-side resources and improve processing efficiency.

[0129] For example, in order to help understand the implementation process of the vehicle signal acquisition method obtained by combining this embodiment with the above-mentioned embodiment 4, please refer to Fig. 9 , Fig. 9 A brief flow chart of a vehicle signal acquisition method is provided, specifically:

[0130] Receive the original CAN message from the vehicle, mark it with a self-increasing sequence in the order of message arrival, then deduplicate the data, delete the duplicate data frames (RX data frames / TX data frames), and retain the latest CAN message corresponding to the same CAN ID within 10ms, remove other messages, and add a timestamp to the deduplicated message, parse the CAN message to obtain the vehicle signal, and after priority management of the collection tasks, determine the currently running task, collect the required signal from the parsed vehicle signal, deduplicate the time period of the collected data before uploading the data, and only upload data in different time periods to the cloud.
