Detailed ways

In order to make the technical solutions and advantages of the present application clearer, the following further describes the present application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

The parallel refresh method of the vehicle controller provided in this application can be applied to the application environment as shown in FIG. 1. The configuration tool 102 communicates with the refresh terminal 104 through the network, and the refresh terminal 104 communicates with the forwarding engine 106 installed on the vehicle through the network. Specifically, the user needs to load the refresh file into the configuration tool 102, so that the configuration tool 102 groups the refresh files according to the bus type of each controller to be refreshed, so that the controller to be refreshed corresponding to the refresh files of different groups can be configured as In parallel refresh mode, the controller to be refreshed corresponding to the refresh file in each group is configured in sequential refresh mode. The configuration tool 102 sends the configured refresh file to the refresh terminal 104, so that the refresh terminal 104 groups different bus types according to the refresh file group. The controllers to be refreshed are refreshed in parallel, and the controllers to be refreshed of the same bus type are refreshed sequentially, that is, the refresh terminal 104 refreshes the corresponding refresh file to the corresponding controller to be refreshed through the forwarding engine 106, so that different groups of refreshes are refreshed. The controller to be refreshed corresponding to the file is in parallel refresh mode, and the controller to be refreshed corresponding to the refresh file in each group is in sequential refresh mode, so that the transmission rate of the high-speed communication link can be fully utilized when refreshing, and the parallel refresh mode improves Refresh efficiency. The refresh terminal 104 can be, but is not limited to, various personal computers, laptops, smart phones, tablets, and portable wearable devices. The refresh terminal 104 supports linux, and can also support various operating environments such as Android and IOS for use in the engineering phase. Production line filling, after-sales, OTA upgrades all links and equipment carriers. The configuration tool 102 may be implemented by an independent server or a server cluster composed of multiple servers.

In one of the embodiments, as shown in FIG. 2, a parallel refresh method for vehicle controllers is provided. Taking the method applied to the configuration tool in FIG. 1 as an example for description, the method includes the following steps:

S202: Receive a refresh file of each controller to be refreshed of the vehicle.

For specific addresses, the controller to be refreshed refers to the controller ECU that needs to be changed in various programs on the vehicle, including engine ECU, body electrical ECU, transmission ECU, and rear auxiliary parking ECU, etc. The refresh file refers to the target file refreshed into the controller, such as S19 file, HEX file, MOT file, etc.

The user imports or sends the refresh file of each controller to be refreshed that needs to be upgraded to the configuration tool, so that the configuration tool can generate a corresponding refresh strategy according to the refresh file of each controller to be refreshed. And optionally, the configuration tool can preprocess the refresh file, such as format conversion, parameter extraction (including the controller to be refreshed corresponding to the refresh file, bus type, baud rate, etc.) to facilitate the generation of the refresh strategy.

S204: Group the refresh files according to the bus type of each controller to be refreshed.

S206: Configure the to-be-refreshed controllers corresponding to the refresh files of different groups to the parallel refresh mode, and configure the to-be-refreshed controllers corresponding to the refresh files in each group to the sequential refresh mode.

Specifically, the bus types include Ethernet bus, CANFD bus, CAN bus, etc. There are no specific restrictions here. The parallel refresh mode means that the controller corresponding to each refresh file can be refreshed at the same time, and the sequential refresh mode refers to each refresh file. Corresponding controllers can be refreshed into the controllers to be refreshed in a certain order, for example, sorted according to the size of the refreshed files, so that files with small files can be refreshed first, and then files with large files are refreshed. If one of the controllers is to be refreshed If there are multiple refresh files, you need to refresh all the refresh files corresponding to the controller before refreshing the next controller. And optionally, in sequential refresh mode, the current refresh time and the user's car usage habits can be obtained. According to the user's car usage habits and current refresh time, predict the current unused time stage of the vehicle. If the user does not use the time If the stage is not enough to refresh all the controllers to be refreshed, you can sort the refresh files corresponding to each controller to be refreshed in ascending order, and then obtain the control to be refreshed with the smaller total size of the refresh files according to the priority of the order. Refresh, so that part of the refresh can be completed in advance, and when it is judged that the remaining time is insufficient, the refresh can be stopped, so that it can be refreshed when the subsequent time is sufficient, such as refreshing in the middle of the night, and if the time is sufficient, it can be performed in random order Refresh, or it is still possible to give priority to the small file of the controller to be refreshed, and then the large file of the controller to be refreshed.

Since the transmission rate of automotive Ethernet can reach 100Mbps, and the baud rate of CAN is 500kbps, Ethernet is similar to a highway, and CAN or CANFD is a branch route, which forms the feasibility of parallel refresh. Secondly, the size of the refresh file of each controller is different, the execution efficiency is different, and the transmission rate of the bus where it is located is also different. Therefore, the parallel efficiency can be optimized to optimize the refresh speed after configuration.

Because the controllers on the vehicle are connected through different buses, some are connected through the Ethernet bus, some are connected through the CANFD bus, and some are connected through the CAN bus, so that the transmission rate of different buses is different, and different buses can be transmitted in parallel Therefore, the configuration tool can group the refresh files according to the bus type. This is because the refresh file corresponds to the controller to be refreshed, and the controller to be refreshed corresponds to the bus type, so the configuration tool can first obtain the refresh file The corresponding controller to be refreshed is then grouped according to the bus type corresponding to the controller to be refreshed. In this way, refresh files in different groups can be in parallel refresh mode, and refresh files in the same group can be in sequential refresh mode.

S208: Send the configured refresh file to the refresh terminal, where the configured refresh file is used to instruct the refresh terminal to refresh each controller to be refreshed in the vehicle in parallel according to the configured refresh file.

Specifically, after the configuration of the refresh file is completed, the configuration tool sends the configured refresh file to the refresh terminal. Optionally, the configuration tool can generate a task package, and then deliver the task package to the refresh terminal, so that the refresh terminal is configured according to the configuration. The completed refresh file refreshes each controller to be refreshed in the vehicle in parallel, for example, controllers on different buses are refreshed in parallel at the same time, and different controllers on the same bus are refreshed in order.

In the parallel refresh method for vehicle controllers, the refresh files are grouped according to the bus type of the controller to be refreshed, so that the controllers to be refreshed corresponding to the refresh files in different groups are in parallel refresh mode, and the refresh file in each group corresponds to the control to be refreshed. The device is in a sequential refresh mode, so that the transmission rate of the high-speed communication link can be fully utilized when refreshing, and the refresh efficiency is improved through the parallel refresh mode.

In one of the embodiments, the aforementioned method for parallel refreshing of vehicle controllers further includes: receiving a refresh process of each controller to be refreshed of the vehicle. Before configuring the controller to be refreshed corresponding to the refresh file in each group to the sequential refresh mode, it also includes: calculating the refresh time of each controller to be refreshed according to the refresh file; judging whether the difference in the refresh time of each controller to be refreshed is greater than The preset value; when there is a difference greater than the preset value, the controller to be refreshed corresponding to the refresh file in each group is configured as a sequential refresh mode. And in one of the embodiments, the method further includes: when there is no difference greater than the preset value, configuring the controller to be refreshed corresponding to each refresh file in each group according to the non-data transmission time in the refresh process as Time division multiplexing refresh mode.

Specifically, the refresh process may include before refresh, during refresh, and after refresh. Before refresh, it includes session switching, secure access, and logistics data reading. Refresh includes refresh and verification, including data erasure, data transmission, and transmission exit. , Integrity check and compatibility check, after refreshing, it mainly includes the gray scale of logistics data and restarting to end the refreshing process.

For the sequential refresh of different controllers on the same bus, the time division multiplexing refresh mode can be used. The configuration tool can calculate the refresh time of each controller to be refreshed according to the refresh file and refresh process, and calculate the difference between the refresh times, for example Assuming there are five refresh files from A to E, which respectively correspond to five controllers to be refreshed, the refresh times corresponding to the five refresh files can be calculated respectively, and then the difference between the refresh times can be calculated. The configuration tool then determines whether the calculated difference is greater than the preset value, where the preset value is used to measure the difference in refresh time corresponding to each refresh file. If the difference in refresh time corresponding to each refresh file is large, for example, If there is a refresh file with a refresh time of 1 hour, while the refresh time of other refresh files is only 5 minutes, then the sequential refresh of different controllers on the same bus can be refreshed in sequence, for example, refresh file A after refreshing, and then refresh B Refresh the files until they are all refreshed, and if the refresh time of each refresh file is not much different, you can configure the controller to be refreshed corresponding to each refresh file in each group to be time-division multiplexed according to the non-data transmission time in the refresh process Refresh mode.

The non-data transmission time can be the mandatory waiting time, the data verification time, and/or the data erasing time. In the time division multiplexing mode, when the refresh flow of one of the controllers to be refreshed is in the above non-data transmission flow, the refresh flow of the other to be refreshed controller is controlled to be in the data transmission flow, that is, as much as possible during this time interval. Other controllers transmit data, so that the Ethernet can always carry on data transmission, making the transmission efficiency of the Ethernet the highest.

In the above embodiment, before the controller to be refreshed corresponding to the refresh file in each group is configured in sequential refresh mode, the refresh time of each controller to be refreshed is also calculated, so that it can be judged whether there is a controller to be refreshed with a longer refresh time. If it exists, the refresh time of the controller to be refreshed is long, so each controller to be refreshed in each parallel refresh group can be refreshed sequentially. Under the premise of ensuring refresh efficiency, full consideration of each controller to be refreshed The difference. If it does not exist, the refresh time of the controller to be refreshed is basically the same. Therefore, in order to further improve the refresh efficiency, you can configure the controller to be refreshed corresponding to each refresh file in each group according to the non-data transmission time in the refresh process. Time-division multiplexing refresh mode, so that through the time-division multiplexing refresh mode, each bus is multiplexed to further improve efficiency.

In one of the embodiments, calculating the refresh time of each controller to be refreshed according to the refresh file includes: calculating the data erasing time according to the size of the refresh file and the single block erasing time of the controller to be refreshed; Calculate the total number of data packets based on the size and the single data packet in transmission; calculate the data transmission time based on the total number of data packets, single data packet transmission time, data writing time, and mandatory waiting time; calculate based on the size of the refresh file and the check speed Data verification time; statistics data erasure time, data transmission time and data verification time get the refresh time.

Specifically, the configuration tool can calculate the refresh time according to the size of the refresh file of the configuration process of the controller to be refreshed, for example, according to the following formula:

T1 (data erasing time) = total number of bytes to refresh the file/single block erasing time.

T2 (data transmission time) = (total bytes of the refresh file/single packet data length) x ((single transmission time + single write time) + P3 (delay control between two data packets)).

T3 (data verification time) = total number of bytes of the refresh file/verification speed.

T (refresh time)=T1+T2+T3.

In the foregoing embodiment, when calculating the refresh time, only the time-consuming difference of each controller to be refreshed, that is, the size of the refresh file, is considered, which can improve the efficiency of calculation.

In one embodiment, as shown in FIG. 3, a parallel refresh method for vehicle controllers is provided. The method is applied to the refresh terminal in FIG. 1 as an example for description, where the refresh terminal is connected to the vehicle through a high-speed communication link. , The high-speed communication link may be an Ethernet link, including the following steps:

S302: Receive the configured refresh file sent by the configuration tool. After the configured refresh file is grouped according to the bus type, the controllers to be refreshed corresponding to the refresh files of different groups are in parallel refresh mode, and the refresh file in each group corresponds to the refresh file. The controller to be refreshed is in sequential refresh mode.

Specifically, after the refresh terminal receives the configured refresh file sent by the configuration tool, it reads the communication parameters of the corresponding controller, such as the corresponding CAN, CANFD bus, bus baud rate, and ECU diagnosis request ID And Response ID, etc., and then perform session switching, for example, set the controllers to be refreshed to refresh mode, that is, the synchronization of the refresh mode of the controllers. Synchronization is to allow all controllers in the vehicle to enter the refresh session at the same time, and in parallel process Maintain the session in the middle, and exit the session uniformly after completion.

S304: Perform parallel refresh on the controllers to be refreshed of different bus types according to the grouping of the refresh files, and perform sequential refresh on the controllers to be refreshed of the same bus type.

Specifically, after each controller of the vehicle enters the refresh mode, the refresh terminal can send a refresh file to the forwarding engine. The forwarding engine is used for the conversion between DOIP protocol ISO-13400 and CAN TP CANFD TP ISO-15765. This engine The requirement is high forwarding efficiency, which can be a dedicated conversion device or a software module based on the in-car gateway. The refresh terminal refreshes the controllers to be refreshed of different bus types in parallel according to the grouping of the new files, and refreshes the controllers to be refreshed of the same bus type sequentially, thereby improving the efficiency of refreshing.

Optionally, refreshing controllers to be refreshed of different bus types in parallel according to the grouping of refresh files, after sequential refreshing of the controllers to be refreshed of the same bus type, further includes: generating and saving a refresh log. In this way, after the refresh is completed, a refresh log is also generated to facilitate the follow-up.

The aforementioned vehicle controller parallel refresh method groups the refresh files according to the bus type of the controllers to be refreshed, so that the controllers to be refreshed corresponding to the refresh files of different groups are in parallel refresh mode, and the refresh files in each group correspond to the control to be refreshed. The device is in a sequential refresh mode, so that the transmission rate of the high-speed communication link can be fully utilized when refreshing, and the refresh efficiency is improved through the parallel refresh mode. In addition, the aforementioned vehicle controller parallel refresh method is highly versatile, and can be used without changing the original controller software or modifying the parallel mechanism; it has strong compatibility and can be used for multiple platforms, such as traditional computers, diagnostics, and vehicles. Networking can be deployed; fast speed, parallel optimization of Ethernet itself, optimization of parallel efficiency of Ethernet to CAN, CANFD, fully improve refresh efficiency, shorten time, and improve service and user experience for OEMs.

In one of the embodiments, the controllers to be refreshed of different bus types are refreshed in parallel according to the group of refresh files. Before the controllers to be refreshed of the same bus type are sequentially refreshed, the method further includes: obtaining the bus type corresponding to the group of the refresh files. The communication protocol; convert the refresh file transmitted through the high-speed communication link into the refresh file corresponding to the communication protocol.

Specifically, this part is the job of refreshing the engine, that is, the conversion of DOIP protocol ISO-13400 and CAN TP CANFD TP ISO-15765. The refresh engine can group the corresponding bus type communication protocol according to the refresh file, and then convert the refresh file transmitted through the high-speed communication link into the refresh file corresponding to the communication protocol, that is, convert the Ethernet communication protocol to CAN, CANFD communication protocol, or Convert CAN and CANFD communication protocols to Ethernet communication protocols, for example, convert ISO-13400 of DOIP to ISO-15765 of CAN TP CANFD TP, or convert ISO-15765 of CAN TP CANFD TP to ISO-13400 of DOIP.

In the above embodiment, the refresh file transmitted through the high-speed communication link is converted into a refresh file corresponding to the communication protocol, and then transmitted to each bus to facilitate transmission to each controller to be refreshed. Through pre-protocol conversion, the subsequent processing can be improved. Refresh efficiency.

In one of the embodiments, the controllers to be refreshed of different bus types are refreshed in parallel according to the grouping of the refresh files. Before the controllers to be refreshed of the same bus type are sequentially refreshed, the method further includes: obtaining the current state of the vehicle; Whether the current state meets the refresh condition; when the current state of the vehicle meets the refresh condition, the controllers to be refreshed of different bus types are refreshed in parallel according to the grouping of the refresh files, and the controllers to be refreshed of the same bus type are refreshed sequentially.

Specifically, the current state of the vehicle may be judged based on data collected by various sensors of the vehicle, for example, based on vehicle speed, gear, or battery voltage. For example, to determine whether the vehicle is in a driving state, if the vehicle is in a driving state, the refresh condition is not met, otherwise, the refresh condition is met. If the vehicle meets the refresh condition, the controllers to be refreshed of different bus types can be paralleled according to the grouping of the refresh files. Refresh, the controller to be refreshed of the same bus type performs sequential refresh.

In the above-mentioned embodiment, before refreshing, the state of the vehicle is also judged, which can prevent the refreshing during the operation of the vehicle from causing danger or causing damage to the controller.

In one of the embodiments, the controllers to be refreshed of different bus types are refreshed in parallel according to the grouping of the refresh files. Before the controllers to be refreshed of the same bus type are sequentially refreshed, it further includes: The refresh controller broadcasts so that each controller to be refreshed enters the refresh mode synchronously.

Specifically, there are often many ECU devices on the bus. As a diagnostic device, it can communicate with all ECUs or designate a certain ECU to communicate alone. Therefore, there are two addressing modes: Functionally Addressed and Physically Addressed. The functional addressing can broadcast the diagnostic request Request, while waiting for the response from the ECU on the bus. Physical addressing specifies to send a specific diagnosis request Request, and wait for the specified ECU to give a response. The refresh terminal can broadcast to the controller to be refreshed through functional addressing or physical addressing, for example, a broadcast to enter the refresh mode, so that each controller to be refreshed enters the refresh mode synchronously, and after the refresh is completed, it can proceed. The logistics data is read back to end the refresh and restart to make each controller work normally.

In the foregoing embodiment, the diagnostic function addressing method is used to ensure that each controller to be refreshed enters the refresh mode synchronously, and then refreshes in parallel, which improves refresh efficiency.

Refer to Figure 4, which is a complete flow chart of a parallel refresh method for vehicle controllers in an embodiment. In this embodiment, the user imports the refresh process and the refresh file into the configuration tool, and the configuration tool performs calculations to obtain the refresh strategy. For example, the refresh files are grouped according to the bus type of each controller to be refreshed, and then the controllers to be refreshed corresponding to the refresh files of different groups are configured as parallel refresh mode, and the controller to be refreshed corresponding to the refresh files in each group is configured as sequential refresh. In this way, the refresh strategy is obtained. The configuration tool loads the refresh strategy to the refresh terminal. Optionally, the configuration tool can also be installed in the refresh terminal, which can facilitate operation. After the refresh terminal receives the refresh strategy, it first judges whether the current vehicle state is Refresh is allowed. If the refresh is allowed, the refresh terminal refreshes the controllers to be refreshed of different bus types in parallel according to the grouping of the refresh files. The controllers to be refreshed of the same bus type are refreshed sequentially. After the refresh is completed, a log is generated for saving. For tracking.

The aforementioned vehicle controller parallel refresh method is highly versatile and can be used without changing the software of the original controller or modifying the parallel mechanism; it has strong compatibility and can be used for multiple platform operations, traditional computers, diagnostics, and Internet of Vehicles. Can be deployed; fast speed, parallel optimization of Ethernet itself, optimization of parallel efficiency of Ethernet to CAN, CANFD, fully improve refresh efficiency, shorten time, and improve service and user experience for OEMs.
