[0056] Optionally, as an optional implementation manner, as shown in Figure 2 The observation data transmission method includes:

[0057] S202, acquiring at least two transmission bandwidths and at least one first observation data, wherein the transmission bandwidth is used to transmit allocated observation data, the first observation data is observation data that is not allocated to any of the at least two transmission bandwidths, and the data occupancy of any observation data in the at least one first observation data is greater than the allocated free amount corresponding to any transmission bandwidth, and the allocated free amount is used to represent the data occupancy of the observation data allowed to be allocated by the transmission bandwidth;

[0058] S204, splitting the first observation data in the at least one first observation data based on the free allocated amount corresponding to each of the at least two transmission bandwidths, to obtain at least two observation sub-data, wherein the data occupancy of any observation sub-data in the at least two observation sub-data is less than or equal to the allocated free amount corresponding to any transmission bandwidth;

[0059] S206, allocating each of the at least two observation sub-data to the at least two transmission bandwidths for data transmission.

[0060] According to an aspect of the embodiments of the present application, a kind of observation data transmission method is provided, optionally, as an optional implementation, the observation data transmission method can be applied to, but not limited to, as shown in the intelligent driving function integrated system of Figure 3 Intelligent driving function integrated system. Wherein the intelligent driving function integrated system can include, but not limited to, file analysis function module 3002, front-end observation quantity screening function module 3004, observation function module 3006, file writing function module 3008.

[0061] Specific process can be as follows:

[0062] Step S302, file analysis function module 3002 obtains the file containing a large number of vehicle body data from vehicle-mounted sensor, and carries out analysis;

[0063] Step S304, front-end observation quantity screening function module 3004 obtains the observation data after file analysis function module 3002 is parsed, and carries out display;

[0064] Step S306, observation function module 3006 carries out relevant data transmission and configuration according to user operation, wherein user operation is used to indicate the data type of selection observation;

[0065] Step S308, file writing function module 3008 obtains the data transmitted by observation function module 3006, and carries out storage, for subsequent test and analysis.

[0066] In addition to Figure 3 The above steps can be completed independently by a plurality of modules, or by the cooperation of the above modules, and the specific implementation mode of the plurality of modules is not limited by the present application.

[0067] Optionally, in the embodiment, the transmission bandwidth in step S202 can be, but is not limited to, understood as the maximum frequency bandwidth of the transmission signal that can be effectively passed through the transmission channel during the transmission process. The transmission bandwidth is used to transmit the observation data that has been allocated. The observation data can be, but is not limited to, understood as a large amount of vehicle body data collected by different types of vehicle-mounted sensors. After the user selects, the data to be observed is determined as the first observation data from the large amount of vehicle body data. After the first observation data is determined, the first observation data needs to be allocated to different data packets for transmission. The data packet can be, but is not limited to, an object descriptor table (ODT) describing a specific data unit item. The allocation manner can be, but is not limited to, according to the analysis difficulty of the first observation data or according to the occupied space size of the first observation data. For example, the speed data of the first observation data has a large analysis difficulty, so the first observation data corresponding to the speed type is preferentially allocated. For example, the first observation data of the environment type has a large occupied space, so the first observation data corresponding to the environment type is placed last for allocation.

[0068] Optionally, in the embodiment, after the first observation data is obtained, the first observation data can be, but is not limited to, allocated to the ODT for transmission. It needs to be noted that each ODT corresponds to a message, and one ODT occupies one transmission bandwidth. The data occupancy of any observation data in the first observation data can be, but is not limited to, understood as the number of occupied bytes. For example, UBYTE occupies 1 byte, UWORD occupies 2 bytes, FLOAT occupies 4 bytes, and DOUBLE occupies 8 bytes. The allocation free amount can be, but is not limited to, indicating the data occupancy of the observation data allowed to be allocated by the transmission bandwidth. For example, one ODT can only transport an idle allocation amount of 7 bytes. Since each ODT occupies one transmission bandwidth, the first observation data corresponding to the DOUBLE observation type cannot be transmitted.

[0069] Optionally, in the embodiment, in step S204, in the case that the data occupancy of at least one first observation data is greater than the allocation free amount corresponding to the transmission bandwidth, the first observation data in the first observation data is split to obtain two observation sub-data. The data occupancy of the observation sub-data is less than or equal to the allocation free amount corresponding to the transmission bandwidth. Optionally, in the embodiment, in the case that the data occupancy of at least one first observation data is less than the allocation free amount corresponding to the transmission bandwidth, the first observation data in the first observation data is combined to obtain observation sub-data. The data occupancy of the observation sub-data is less than or equal to the allocation free amount corresponding to the transmission bandwidth.

[0070] It should be noted that through the allocation strategy in the above embodiment, the first observation data is split and combined according to the size of the observation data amount occupying space, so as to determine new observation sub-data. The observation sub-data can be understood as, but is not limited to, observation data that is split and combined and is to be allocated to a transmission bandwidth for transmission. Through the optimization of data allocation, the number of transmission bandwidths is a minimum value, and the data is only split as necessary. Therefore, the subsequent process steps corresponding to data analysis are relatively minimal, the efficiency of host computer analysis is improved, and the data observation efficiency is improved.

[0071] Optionally, for example Figure 4 As shown, the data collected in real time from the body perception sensor is obtained. After a user selects some to-be-observed data in the software interface, the program internally iterates the types of observation amounts in sequence, determines that the data occupying amount of the first observation data 402 of type A is 8 bytes, which is greater than the allocation idle amount of any transmission bandwidth, which is 7 bytes. Therefore, the first observation data 402 is split to obtain at least two observation sub-data 404, which are 7 bytes and 1 byte of observation sub-data 404. The observation sub-data 404 is allocated to two transmission bandwidths 406 for transmission.

[0072] Optionally, the data collected in real time from the environment perception sensor is obtained. The occupying spaces of all observation data types are iterated. N first observation data greater than the allocation idle amount of the transmission bandwidth are preferentially split and combined into M observation sub-data, and it is ensured that the data occupying amount of M-1 observation sub-data is equal to the maximum allocation idle amount of any transmission bandwidth. The remaining observation sub-data is combined with the first observation data corresponding to the allocation idle amount less than the transmission bandwidth.

[0073] Specifically, for example Figure 5 As shown, a user wants to observe the first observation data 502 corresponding to type B, the first observation data 504 corresponding to type C, and the first observation data 506 corresponding to type D. The type B occupies 7 bytes, the type C occupies 2 bytes, the type D occupies 6 bytes, and the maximum allocation idle amount corresponding to any transmission bandwidth occupies 5 bytes. The observation data corresponding to the type B is preferentially split into 5 bytes and 2 bytes. The 2 bytes are combined with the type C. However, the observation data amount after combination is still less than the maximum allocation idle amount of the transmission bandwidth. Therefore, the first observation data of the type D is split into 1 byte and 5 bytes. The 2 bytes of the type B are combined with all of the type C and the 1 byte of the type D. Three groups of observation sub-data to be transmitted are formed. Each observation sub-data is allocated to a different ODT data packet 508. Each ODT data packet occupies a transmission bandwidth. The transmission of data is completed.

[0074] It should be noted that the original allocation strategy is optimized by the above splitting and combining, and the number of ODT transmission data packets is minimized compared to the prior art, improving the efficiency of data transmission.

[0075] In the embodiment of the present application, at least two transmission bandwidths and at least one first observation data are obtained, wherein the transmission bandwidth is used to transmit the allocated observation data, the first observation data is the observation data not allocated to any of the at least two transmission bandwidths, and the data occupancy of any observation data in the at least one first observation data is greater than the allocated free amount corresponding to any transmission bandwidth, and the allocated free amount is used to represent the data occupancy of the observation data allowed to be allocated by the transmission bandwidth; based on the free allocation amount corresponding to each of the at least two transmission bandwidths, the first observation data in the at least one first observation data is split to obtain at least two observation sub-data, wherein the data occupancy of any observation sub-data in the at least two observation sub-data is less than or equal to the allocated free amount corresponding to any transmission bandwidth; each observation sub-data in the at least two observation sub-data is allocated to the at least two transmission bandwidths for data transmission, and when the observation data to be transmitted is obtained, the observation data to be transmitted is split according to the free allocation amount of the transmission bandwidth, and the split observation sub-data is allocated to the transmission bandwidth for data transmission, thereby achieving the purpose of reducing the occupied number of bandwidth and realizing the technical effect of improving the transmission efficiency of observation data.

[0076] As an optional solution, splitting the first observation data in the at least one first observation data based on the free allocation amount corresponding to each of the at least two transmission bandwidths includes:

[0077] Obtaining the maximum number of at least two transmission bandwidths, wherein the maximum number of at least two transmission bandwidths is used to represent the maximum allocated free amount corresponding to a single transmission bandwidth in the at least two transmission bandwidths;

[0078] In the first observation data set, the data occupancy corresponding to the first observation data is traversed to determine a second observation data whose data occupancy is greater than the maximum number of bearers;

[0079] Splitting the second observation data to obtain N second observation sub-data, wherein N is an integer greater than 1, and the data occupancy of at least one second observation sub-data in the N second observation sub-data is equal to the maximum number of bearers.

[0080] Optionally, in this embodiment, after the maximum number of bearers of the transmission bandwidth is obtained, the data occupancy corresponding to the first observation data in the first observation data set is sequentially traversed, and the second observation data corresponding to the data occupancy of the first observation data is greater than the maximum number of bearers is selected for splitting first, and N second observation sub-data is obtained.

[0081] Through the embodiments provided in the application, the maximum number of bearers of at least two transmission bandwidths is obtained, wherein the maximum number of bearers is used to represent the maximum allocation idle amount corresponding to a single transmission bandwidth in the at least two transmission bandwidths; the data occupancy corresponding to the first observation data in the first observation data set is traversed to determine the second observation data corresponding to the data occupancy of the first observation data is greater than the maximum number of bearers; the second observation data is split to obtain N second observation sub-data, wherein N is an integer greater than 1, and the data occupancy corresponding to at least one second observation sub-data in the N second observation sub-data is equal to the maximum load, thereby achieving the purpose of automatically splitting the observation data with a larger data occupancy, and thereby achieving the technical effect of improving data processing efficiency.

[0082] As an optional solution, after the maximum number of bearers of at least two transmission bandwidths is obtained, the following steps are further included:

[0083] The data occupancy corresponding to the first observation data in the first observation data set is traversed to determine the third observation data corresponding to the data occupancy of the first observation data is less than the maximum load.

[0084] The third observation data is combined to obtain M third observation sub-data, wherein M is a natural number, and the data occupancy corresponding to the third observation sub-data is less than or equal to the maximum load.

[0085] Optionally, in this embodiment, the observation data corresponding to the data occupancy of the first observation data in the first observation data set is traversed, and the third observation data corresponding to the data occupancy of the first observation data is less than the maximum load is determined, and the third observation data is combined to obtain M third observation sub-data.

[0086] Through the embodiments provided in the application, the data occupancy corresponding to the first observation data in the first observation data set is traversed to determine the third observation data corresponding to the data occupancy of the first observation data is less than the maximum load; the third observation data is combined to obtain M third observation sub-data, wherein M is a natural number, and the data occupancy corresponding to the third observation sub-data is less than or equal to the maximum load, thereby achieving the purpose of automatically combining the observation data with a smaller data occupancy, and thereby achieving the technical effect of improving data processing efficiency.

[0087] As an optional solution, the maximum number of bearers of at least two transmission bandwidths is obtained, including:

[0088] The upper limit of the single data packet is obtained based on the target protocol, and the single data packet occupies one transmission bandwidth;

[0089] The upper limit of the single data packet is determined as the maximum number of transmission bandwidths.

[0090] Optionally, in the embodiment, the target protocol can be but is not limited to XCP protocol. In order to monitor effective data in a high-efficiency manner, the XCP protocol is used for communication of the lower computer. The XCP protocol is an application layer communication protocol. The upper limit of the single data packet is determined according to the communication protocol. For example, the upper limit of the ODT data packet is 7 bytes. One data packet occupies one transmission bandwidth in transmission. Therefore, the maximum number of transmission bandwidths is determined according to the upper limit of the data packet.

[0091] According to the embodiments provided in the application, the upper limit of the single data packet is obtained based on the target protocol, and the single data packet occupies one transmission bandwidth. The upper limit of the single data packet is determined as the maximum number of transmission bandwidths, thereby achieving the purpose of determining the number of transmission bandwidths based on the upper limit of the data packet, and realizing the technical effects of reducing the pressure of the transmission bandwidth and improving the transmission efficiency.

[0092] As an optional solution, at least two transmission bandwidths and at least one first observation data are obtained, including:

[0093] The target transmission bandwidth in the recharging system and a target observation data set are obtained. The target observation data set includes target observation data of different vehicle-mounted sensor types.

[0094] The target observation data set is distributed to the plurality of target transmission bandwidths for inputting into the recharging system.

[0095] Optionally, in the embodiment, recharging can be understood as simulation with real traffic flow data. Data recharging mainly repackages data record files generated by sensors into data packets and transmits them on a bus. A common data recharging scenario can be but is not limited to understanding that in the field of intelligent driving, a series of data from sensors such as video and radar are uploaded. An intelligent driving processor needs to process, decide and analyze the data. For example, corresponding sensors such as cameras, radars and vehicle bodies collect data and record the data. The data is parsed according to the generated frequency in the laboratory and recharged on the respective protocol bus. It is equivalent to simulating a car running outside in the laboratory, but the data is actually generated, not simulated.

[0096] Multi-channel video data and radar data, for example, different sensors can detect a car in front of the user and the distance from the user, and upload data corresponding to multiple sensor types, and the ADAS system will refer to multi-dimensional sensors to fuse these multiple data, and finally generate only one final conclusion, but without monitoring system, although the user can obtain the original data, but does not know how the controller processes these data, the embodiment can take out the data in the backfilling for real-time subsequent function decision.

[0097] The backfilling system and the monitoring system are separated in the prior art, and if the input parameters are detected during the data backfilling process, an additional monitoring system device needs to be externally connected. The embodiment integrates the backfilling system and the monitoring system together, realizes real-time monitoring of data during the data backfilling process, and improves the data monitoring efficiency.

[0098] Through the embodiments provided in the application, the target transmission bandwidth in the backfilling system and the target observation data set are obtained, the target observation data set includes target observation data of different vehicle-mounted sensor types; the target observation data set is distributed to multiple target transmission bandwidths for inputting into the backfilling system, and the purpose of data transmission in the backfilling application scene is achieved, thereby achieving the technical effect of improving the utilization rate and backfilling efficiency of the device.

[0099] As an optional solution, before responding to the data observation request, the method comprises:

[0100] During the data backfilling, the first collection data uploaded by the multiple vehicle-mounted sensors is obtained;

[0101] The first collection data is continuously input into the data backfilling system and stored in the target storage link table;

[0102] In a case where the data in the target link table meets a first occupied space threshold, the data in the target link table within a preset time period is deleted.

[0103] Optionally, in the embodiment, the target storage link table can be but is not limited to a data link table stored in the memory. When the first collection data is uploaded to the data backfilling system in real time, the first collection data is stored in the target storage link table. The first occupied space threshold can be but is not limited to a data threshold in a time unit or a length unit. For example, when the target data link table stores data of 30 seconds in length, the data is deleted from the head of the target data link table in sequence, and new data is inserted at the tail of the target data link table.

[0104] It should be noted that the integrated recharge system and monitoring system of the present application has the advantages that when some functions or event triggers occur during the recharge process, the data can be saved in real time, for example, the data of the camera and radar is normally recharged during the process, and the user's concerned data is monitored in real time, but the user's concerned data is not always required, for example Figure 6 As shown in the figure, the user is concerned about the function decision made by the system when a pedestrian rushes out on the road, and the first collection data collected by the radar, electromagnetic wave and other sensors in the vehicle 602 normally driving on the road is continuously input into the data recharge system. If no pedestrian rushes out for more than 30 seconds during the data recharge process, no sudden event trigger request is triggered for a period of time, and the historical data 606 in the target data link table 604 is discarded;

[0105] When a pedestrian rushes out, for example Figure 7 As shown in the figure, when the brake request event trigger is detected, the predetermined time period corresponding to the brake time is 30S, only the data 40S before the brake event occurs in the target data link table 704 is retained, and the data in the remaining time is discarded. At this time, the first collection data collected by various sensors in the vehicle 702 is still continuously input into the data recharge system, and the data is always saved in the target data link table 704 during the continuous data recharge process. When the user wants to retrieve the data for analysis, only the data in the predetermined time period needs to be retrieved, which can reduce the data processing cost and improve the data processing efficiency. The present embodiment can realize real-time storage of data through one recharge, while the monitoring system and data recharge system in the prior art are not integrated, and the current data when braking cannot be completely restored. A monitoring system needs to be connected to re-record the data under the same situation, which cannot guarantee the accuracy of the recharge. The present embodiment overcomes the technical problem of poor data recharge restoration in the prior art.

[0106] Through the embodiments provided by the present application, during the data recharge period, the first collection data uploaded by the plurality of vehicle-mounted sensors is obtained; the first collection data is continuously input into the data recharge system and stored in the target storage link table; in the case that the data in the target link table meets the first occupation space threshold, the data in the target link table within the preset time period is deleted, thereby achieving the purpose of real-time data storage and timely cleaning, and realizing the technical effect of improving the efficiency of data storage.

[0107] As an optional solution, obtaining at least two transmission bandwidths and at least one first observation data includes:

[0108] In the case of obtaining an event trigger request, a corresponding predetermined time length is obtained according to the event type;

[0109] The data in the preset time length corresponding to the target storage chain table is determined as the first observation data.

[0110] Optionally, in the embodiment, the event trigger request can be, but is not limited to, a trigger request corresponding to a corresponding reaction of the automobile according to the above-mentioned burst event when a preset event burst is detected, and the predetermined time length corresponding to different event types can be different. For example, the predetermined time length corresponding to the brake event trigger request can be 30s, and the predetermined time length corresponding to the turning event trigger request can be 60s. Further, the data in the target storage chain table corresponding to the time length is saved for subsequent observation.

[0111] Through the embodiments provided in the application, in the case of obtaining an event trigger request, the corresponding predetermined time length is obtained according to the event type; the data in the preset time length corresponding to the target storage chain table is determined as the first observation data, thereby achieving the technical effect of improving the accuracy of data backfilling.

[0112] As an optional solution, obtaining at least two transmission bandwidths and at least one first observation data includes:

[0113] In response to a data observation request, the file is parsed and a to-be-observed list is displayed, wherein the to-be-observed list is used to show all to-be-observed data.

[0114] At least one first observation data is determined from the to-be-observed list based on a business requirement.

[0115] Optionally, in the embodiment, for example Figure 8 As shown in the figure, after obtaining the to-be-processed data file, the file is parsed, and all to-be-observed data is displayed in the to-be-observed list. At least one first observation data is determined from the to-be-observed list based on a business requirement or user selection.

[0116] Through the embodiments provided in the application, in response to a data observation request, the file is parsed and a to-be-observed list is displayed, wherein the to-be-observed list is used to show all to-be-observed data; at least one first observation data is determined from the to-be-observed list based on a business requirement, thereby achieving the purpose of improving the flexibility of selecting to-be-observed data, and realizing the technical effect of flexibility of data observation.

[0117] As an optional solution, the observation data transmission method is applied in an intelligent driving backfilling scene, for example Figure 9 As shown in the figure, the specific steps are as follows:

[0118] Step S902: user interface selection;

[0119] Step S904: According to the user interface, start to parse a file format definition information file required for communication between the host computer and the ECU (a file format definition information file required for communication between the host computer and the ECU, referred to as A2L): parse the A2L file generated at the time of compilation from the A2L database of the host computer;

[0120] Step S906: Display all observation variables: present the observation variable list in the ECU microprocessor (Electronic Control Unit, referred to as ECU) to the user interface for user selection;

[0121] Step S908: User selects data, writes variable configuration file: after the user selects some data to be observed in the software interface, the program internally determines the size of the observation variable to be observed by sequentially traversing the type of the observation variable (for example: UBYTE occupies 1 Byte, UWORD occupies 2 Bytes, FLOAT occupies 4 Bytes, DOUBLE occupies 8 Bytes);

[0122] Step S910: Load user, configuration specified variable information;

[0123] Step S912: Plan the size of all selected variables, form a specific data data entry (entry) - a table (odt) describing the target specific data unit entry - a data file (dat) list, and perform ODT allocation on the planned data,

[0124] Optionally, in the embodiment, the allocation strategy can include but is not limited to: first, traverse all 8 Byte size variables in the observation variable, split them into 7 Byte and 1 Byte size, save the corresponding ECU address information to two entries with sizes of 7 Byte and 1 Byte; second, the 7 Byte size part can be directly placed in a complete ODT, then continue to loop through the remaining part and other observation variables to find 1 Byte, 2 Byte, 4 Byte combinations, and form an ODT with the three byte size entries; finally, for the remaining observation variables, continue to loop through and split the remaining excessively large observation variables, for example, if there are 3 4 Byte size observation variables, then split the second observation variable into 3 Byte and 1 Byte, place them into an ODT, set the 3 Byte and the first 4 Byte observation variable to an ODT, and place the 1 Byte and the third 4 Byte variable into the next ODT;

[0125] It should be noted that the observation quantity is allocated into the corresponding ODT according to the optimal strategy. Due to the characteristics of the XCP protocol (XCP on CAN) in the controller bus, each ODT corresponds to a Controller Area Network (CAN) message, wherein the Packet Identifier (PID) occupies at least 1 Byte, and therefore one ODT can carry at most 7 Bytes of data. Therefore, the optimal planning strategy is implemented as follows: the sizes of the remaining ODTs except the last ODT are ensured to be 7 Bytes, and the bus load and slave overhead are not wasted.

[0126] Step S914: Start the Universal Measurement and Calibration Protocol (XCP) configuration process, and allocate the observation quantity into the ODT. After the instruction is set to the slave through the Command Transfer Object (CTO) and the DAQ is started, the slave continuously feeds back the data in the ECU memory. The host parses the data into the values of the corresponding observation quantities through the information allocated by the allocation strategy. Due to the optimization of the allocation strategy, the number of ODTs is minimized, and the data is only split as necessary. Therefore, the parsing process steps are also relatively minimal, and the parsing efficiency of the host is improved.

[0127] Step S916: Continuously acquire the Data AcQuisition (DAQ) data from the Measurement Data Format (MDF) database and save it to the MDF4 file.

[0128] Step S918: Determine whether the program is ended. If yes, the process is directly stopped; if not, return to step S914 to continue saving the data.

[0129] Optionally, in the embodiment, during data backfilling, for monitoring ADAS function trigger time specific data in ADAS, the host computer stores observation information in a linked list of memory, when the linked list is full of 30 seconds length data, the data is deleted from the head of the queue in turn, and the new data is inserted into the tail of the queue. When the backfilling Autonomous Emergency Braking (AEB) or Forward Collision Warning (FCW) event is triggered, all data in the linked list, that is, the data in the past 30 seconds, and the data in the next 30 seconds (the above-mentioned 30 seconds can be configured by the host computer configuration file) are written into the main data file (Measurement Data Format, MDF) file, so as to facilitate subsequent testing and analysis by using industry standard analysis means, and improve problem troubleshooting efficiency.

[0130] It should be noted that for the current device type multiple use scenarios, the XCP backfilling system of the embodiment can support multiple CAN devices. The host computer defines an abstract layer interface of the CAN interface, and when different CAN devices are replaced, the device driver can be replaced by replacing the device interface layer code, without changing the application layer code, and the adaptation cost is low.

[0131] Optionally, in the embodiment, the laboratory performs interface configuration and variable screening functions, and checks that the actual configuration is consistent with the expectation; the laboratory performs A2L file analysis functions, and checks that the analysis result is consistent with the expectation; different observation variables are correctly set and real-time observation of correct variable information is consistent with the Vector device; MDF file analysis is correct, ensuring that the DAQ data obtained and the data collected are consistent.

[0132] It should be noted that the embodiment has the following advantages: the backfilling system in the embodiment makes a global optimal planning strategy for all observation information before issuing all observation information, reduces Bus Load overhead, and improves observation efficiency; during the backfilling process, the corresponding observation information is recorded at the trigger time, redundant data recording is reduced, and problem troubleshooting efficiency is improved; the existing backfilling platform is developed, the hardware integration is high, the CAN device is self-developed, the device cost is low, and the CAN device of other brands is compatible, the overall adaptability is good; automatic trigger data recording is achieved, one backfilling record data process of the backfilling system is saved, and labor cost is reduced; the recorded MDF file data is a standard file format and can be opened and used by other industry standard software; the real-time performance is good, and all signals can be guaranteed in the same calculation period.

[0133] Through the embodiments provided in the present application, first, the user selects to open the XCP protocol tool in the recharge system interface, starts to parse the A2L file according to the user selection, and displays all the observation information after parsing all the A2L files. Secondly, according to the user's selection of the required data information, the variable configuration file is written. By loading the configuration variable information, the optimal planning strategy is selected, and then the XCP configuration process is started. Finally, the continuously acquired DAQ data is saved to the MDF file, so as to facilitate subsequent test analysis.

[0134] For an increasing number of vehicle body data, when using the ADAS recharge function, it is necessary to monitor specific data in the ADAS when the ADAS function is triggered, such as vehicle speed, steering wheel angle, vehicle body angular velocity yaw rate, etc. The embodiment monitors the effective data in the ADAS in a more efficient and most direct way, acquires the required observation and saves it into a general and easy-to-analyze data. Specifically, the user wants to know the change of the vehicle speed when the vehicle travels to different road sections. The vehicle speed type data is checked on the data recharge display interface. The electromagnetic wave sensor and the radar sensor have acquired the vehicle speed type data. At this time, the program internally iterates the size of the data amount of the uploaded observation data from the electromagnetic wave sensor and the radar sensor, splits the above observation data according to the splitting strategy and combination strategy, and allocates them to different ODTs for bandwidth transmission. The size of the remaining ODTs except the last ODT is guaranteed to be the maximum carrying capacity during splitting, which reduces the number of transmission bandwidth and improves the transmission efficiency. The user can observe and store the running results of the data collected by the electromagnetic wave sensor and the radar sensor in the processor in real time during data recharge, which guarantees the timeliness of the data and achieves the purpose of efficient monitoring of the observation data.
