Particularly, transport module 121 is for sending transmission mode sign on by communication interface 110 to vehicle control device, so that the Boot loader of vehicle control device enters transmission mode.In transmission mode, transmit the resolution data line number of the application file of wanting programming and the start address of resolution data.
Sending module 123 sends data message for the continuous data frame with preset number to vehicle control device.The data content that sends the application file of resolving when programming with successive frame, for example successive frame N is determined by the data amount check of every row, if number is less than or equal to the number that single frames transmits, sends with single frame.
Wipe module 124 and send erasing instruction by communication interface 110 to vehicle control device, the reference position of the memory bank that will wipe is sent to vehicle control device.Start address by the resolution data of application file sends to vehicle control device and confirms link order, until confirm that the work of wiping completes.
Programming progress demonstration that display module 126 sends for receiving sending module 123.In the time completing with the data line of successive frame transmission application file, show that the value of programming progress number increases a step-length.Wherein, resolution data is capable, as the basis of progress displaying bar step-length, often sends a data line, and progress displaying bar increases a step-length.
Fig. 3 is the system hardware connection layout of the programming device of vehicle control device according to an embodiment of the invention.
As shown in Figure 3, controller 120(PC instrument) by USB interface and communication interface 110(CAN communication tool interface) be connected, communication interface 110(CAN communication tool interface) be connected with vehicle control device by CAN bus.Controller 120(PC instrument) be for example but be not limited to PC.In one embodiment of the invention, preferably, communication interface 110 is based on CAN bus ISO015765-3 agreement.And this device can compatible multiple CAN communication tool interface, can and record time, the content of CAN bus data, real time inspection download progress by debug window Real Time Observation.
As shown in Figure 3, controller 120(PC instrument) software by communication interface 110(CAN communication tool interface) with vehicle control device carry out communication, resolve line by line and send application file data content, and carry out data transmission in the mode of successive frame, therefore in the situation that CAN baud rate is certain, reduce the response times of controller, thereby reduced data transmission period, improved work efficiency.And this device can compatible multiple CAN communication crossover tool, increase the dirigibility using.
As a concrete example, Fig. 4 is the workflow diagram of the programming device of vehicle control device according to an embodiment of the invention.
As shown in Figure 4, the workflow diagram of the programming device of vehicle control device according to an embodiment of the invention, comprises the following steps:
Step S401, starts.Be that programming work starts.
Step S402, controller carries out initialization to equipment, file.
Particularly, first by graphical interfaces initialization CAN bus baud rate, set ID identification shielding scope, to get rid of incoherent CAN bus message, thus the work efficiency of raising flashburn tools.Then specify the application file that will transmit programming, traversal file resolution file, the resolution data line number of acquisition file, as the basis of programming progress displaying bar step-length.The start address of last resolution data, the start address when wiping file data.
Step S403, enters transmission mode.
Controller sends transmission mode sign on by CAN bus to vehicle control device, makes vehicle control device bootloader enter transmission mode, under transmission mode, and the file data line number of resolving in transmitting step S402 and the start address of resolution data.
Step S404, safety certification.
In order to ensure the security permission of data programming, controller sends safety certification instruction and carries out safety certification, and confirms link order, to determine that whether certification is successful.
Step S405, whether certification is successful.Judge that whether safety certification is successful, if success continues execution step S406, otherwise execution step S417, i.e. EOP (end of program).
Step S406, starts to send erasing instruction.
After safety certification success, controller sends erasing instruction to vehicle control device, the start address of the application file data that will wipe of resolving in step S402 is sent to vehicle control device, and confirm link order, until confirm that the work of wiping completes.
Step S407, whether judgement is wiped and is completed.Wipe work by the judgement of confirmation link order and whether complete, if completed, perform step S408, otherwise execution step S417.
Step S408, transmission start address.
Be that programming process starts, the application file of specifying in analyzing step S402 line by line, parses address, data amount check and the data content of data line.Wherein, application file data behavior string format, need to be converted into ASCII fromat by transfer function and judge and send, and the data line start address of the application file after being parsed is sent to entire car controller, and confirm link order, be transmitted judging whether.
Step S409, by confirming link order judges whether the data line start address of resolving is transmitted, if completed, performs step S410, otherwise execution step S417.
Step S410, with successive frame transmission data.
The data content of the application file of resolving with successive frame transmission, for example successive frame N is determined by the data amount check of every row, if number is less than or equal to the number that single needle transmits, sends with single frame.Resolve line by line the also data content of transfer files, transfer the data content of a successive frame N, progress displaying bar numerical value increases a step-length.
Whether step S411, be transmitted according to the data line content of the application file of resolving in progress bar numerical value determining step S410, if completed, performs step S412, otherwise execution step S417.
Step S412, programming successive frame data.
The data line content of transmitting in the boot loader programming step S410 by vehicle control device, and confirm link order, to judge whether programming is successfully completed.
Step S413, by confirming link order, judges whether programming completes.If completed, perform step S414, otherwise execution step S417.
Step S414, judges whether application file data content all transmits and programming completes, and if it is performs step S415, otherwise execution step S408 continues the also data content of programming resolution file of transmission.
Step S415, exits transmission mode.After determining the whole end of transmissions of application file data content of resolving and programming completes, exit transmission mode, programming process finishes.
Step S416, restarts vehicle control device.After programming process finishes, controller sends instruction, and vehicle control device is restarted, and now progress bar has shown, shows and confirms dialog box, confirms that programming process finishes.
Step S417, EOP (end of program), while going wrong in transmission or programming process, operation failure, finishes and quits a program.
According to the programming device of the vehicle control device of the embodiment of the present invention, can compatible multiple CAN communication crossover tool, communicate based on CAN bus ISO015765-3 agreement and vehicle control device, can resolve line by line the data of application file, and transmit data line content in the mode of successive frame, and can real time inspection and record CAN data, and show by progress bar.In the case of the certain and identical application file of baud rate, than the flashburn tools based on CCP agreement, the response times with controller is few, data transmission period is short, the advantage that work efficiency is high.
