[0028] Example 1

[0029] The method embodiment provided in the first embodiment of the present application can be executed in a vehicle terminal, a computer, a tablet or a similar computing device. Taking running on a computer as an example, Figure 1 is a hardware structure block diagram of a computer in an embodiment of the present application. Figure 1 As shown, the computer may include one or more ( Figure 1Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data. Optionally, the computer may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above-mentioned computer. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown.

[0030] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as a computer program corresponding to a program update method in an embodiment of the present application. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the computer via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0031] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the computer. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0032] In this embodiment, a program update method is provided, which can be applied to a vehicle controller. Figure 2 is a flowchart of a program updating method according to an embodiment of the present application, such as Figure 2 As shown, the process includes the following steps:

[0033] Step S10, detecting whether a program update instruction is received;

[0034] Step S20, in response to the detected program update instruction, obtaining an update type and an updated version of the program corresponding to the program update instruction;

[0035] Step S30, determining the main area corresponding to the update type, and copying the original program in the main area to the corresponding backup area, wherein the main area is used to store the program to be run, and the backup area is used to store the program in the main area;

[0036] Step S40, writing the updated version of the program into the main area, and after the writing is successful, resetting to the main area to run the updated version of the program.

[0037] In this embodiment, after the vehicle controller is powered on, the original startup program in the first main area is first run to detect whether the first program update instruction is received within a preset time (such as 2 seconds). If the first program update instruction is received within the preset time, the corresponding update flag in the parameter area is set to valid (specifically, the startup program update flag or the application program update flag) according to the type of the first program update instruction (specifically, the startup program self-update or the application program update), and the subsequent corresponding program update steps are performed. If the first program update instruction is not received within the preset time, jump to execute the original application in the second main area. In the process of executing the original application, detect whether the second program update instruction sent by the host computer is received. If the second program update instruction sent by the host computer is received during the execution of the original application, the corresponding update flag in the parameter area is set to valid according to the type of the second program update instruction (also the startup program update or the application program update), and finally reset back to the startup program to perform the subsequent corresponding program update steps.

[0038] In this embodiment, the non-volatile memory flash of the controller is partitioned into a main area, a backup area and a parameter area, wherein the main area is used to store the program to be run, the backup area is used to store the last program in the main area, and the parameter area is used to store the flag bits in the update process, and the flag bits include a startup program update flag, an application program update flag, an application program valid flag, a backup area startup program flag, a rollback startup program flag and a startup program flashing flag. Specifically, refer to Figure 3 The main area includes a first main area (bootloader area) for storing the startup program to be run, and a second main area (App area) for storing the application program to be run. The backup area includes a first backup area (bootloader backup area) for storing the startup program originally in the first main area, and a second backup area (App backup area) for storing the application program originally in the second main area. The controller reads the update flag in the parameter area in the startup program to determine the update type corresponding to the program update instruction. If the startup program update flag is valid, the update type is the startup program self-update, and the startup program self-update step is executed; if the application program update flag is valid, the update type is the application program update, and the application program update step is executed.

[0039] Determine the main area corresponding to the update type, and copy the original program in the main area to the corresponding backup area, where the main area is used to store the program to be run, and the backup area is used to back up the program in the main area; write the updated version of the program into the main area, and after the writing is successful, reset to the main area to run the updated version of the program.

[0040] This embodiment uses multiple partitions to copy the programs in the main area to the backup area to back up the programs. During the program update process, even if there is a communication interruption or the program is insufficient after the update is completed, the original program can be rolled back in time to ensure that the controller always has a normal program and guarantee the normal operation of the equipment.

[0041] In the related art, since the boot program is written through the burning port before the controller is installed, the boot program cannot be updated by itself, and the need to update the boot program as the technology improves or the security requirements increase is not considered. In this regard, in one implementation of this embodiment, the update type is the boot program self-update, the updated version program is the updated version boot program, and the method further includes:

[0042] A1, erasing data in the first backup area, where the first backup area is used to store the startup program in the first main area, and the first main area is used to store the startup program to be run;

[0043] A2, copying the original startup program in the first main area to the first backup area, and after the copy is successful, jumping to the first backup area to execute the original startup program;

[0044] A3, during the process of executing the original startup program in the first backup area, writing the updated startup program into the first main area.

[0045] Reference Figure 4 and Figure 5 When the boot program is updated, first erase the data in the first backup area, then copy the original boot program (i.e., the current boot program) in the first main area to the first backup area. Before updating the boot program, back up the original boot program currently in use to another storage area to prevent the update from failing or the new version from having problems, so that it can be quickly rolled back to the old version. Then set the backup area boot program run flag and the boot program write flag in the parameter area to be valid, and turn off the interrupt. By setting the run flag and the write flag, the system can identify the current state (that is, the backup area boot program will be run and the main area boot program will be updated). Turning off the interrupt can avoid external events from interfering during the update process, ensuring the smooth progress of the update process. Finally, jump to the first backup area to run the original boot program. After confirming that the backup area is ready, the system switches to the backup area to execute the boot program. In this way, even if the update of the main area fails, the system can continue to run, ensuring the availability and stability of the system.

[0046] In the startup program running the first backup area, first read the running backup area startup program flag in the parameter area. If the running backup area startup program flag is valid, set the address of the interrupt vector table to the starting address of the first backup area, and then enable the interrupt. After enabling the interrupt, the system can respond to external events, thereby improving the system's responsiveness and real-time performance.

[0047] Then read the boot program update flag and boot program flash flag in the parameter area. If the flag is valid, erase the data in the first main area first, and then write the updated boot program to the first main area. After successful writing, set the boot program flash flag, boot program update flag and running backup area boot program flag to invalid, and finally perform a system reset.

[0048] Through this implementation, the startup program has a self-update function. When updating, it first copies its own data to the startup program backup area, then jumps to the startup program backup area to execute the startup program, and then writes the new startup program to the startup program area, thereby realizing the self-update of the startup program and facilitating the maintenance and technical upgrade of the startup program.

[0049] In another implementation of this embodiment, the update type is an application update, the updated program is an updated application, and the method further includes:

[0050] B1, erasing data in the second backup area, where the second backup area is used to store applications in the second main area, where the second main area is used to store applications to be run;

[0051] B2, copying the original application in the second primary area to the second backup area;

[0052] B3, after the copy is successful, write the updated version of the application to the second main area.

[0053] Reference Figure 4 and Figure 6 When updating the application, first erase the data in the second backup area, then copy the original application (i.e., the current application) in the second main area to the second backup area. Before updating the application, back up the original application currently in use to another storage area to prevent the update from failing or the new version from having problems so that it can be quickly rolled back to the old version. After the copy is successful, write the updated application to the second main area. After the writing is successful, set the application valid flag to valid, set the application update flag to invalid, and finally perform a system reset.

[0054] When updating an application, this embodiment first copies the application to the application backup area, and then writes the new application to the application area, so that if communication is interrupted during the application update, the original program will not be lost, and the normal operation of the device can be maintained.

[0055] In the related art, when updating a program, communication interruption or deficiencies in the updated program cause the controller to fail to operate normally. For example, a laptop is connected to a CAN box via a USB cable, and the CAN box is connected to the interface of the controller or the vehicle via two wires, CAN_H and CAN_L. If the USB cable or CAN cable becomes loose and causes communication interruption, the update process will be interrupted or the transmitted program data will be lost, resulting in program update failure. In this regard, in another implementation of this embodiment, writing the updated version of the program into the main area includes:

[0056] S41, in the process of writing the updated version of the program into the main area, detecting whether the communication is interrupted by a timer;

[0057] S42, if the controller receives information from the host computer within a preset time, it determines that the communication is normal and resets the timer; if the controller times out when receiving information from the host computer, it determines that the communication is interrupted and writes the original program in the backup area back to the main area.

[0058] In the process of writing the updated version of the startup program or the updated version of the application program to the corresponding main area, the controller is equipped with a timer, which detects whether the communication is interrupted. The main function of the timer is to monitor the communication time between the controller and the host computer (such as a server, a personal computer, etc.). By setting a reasonable timeout, the timer can ensure that if the communication does not continue within a certain period of time, it is considered as a communication interruption. When the controller receives information from the host computer within the timed time, it means that the communication is still proceeding normally. At this time, the timer needs to be reset to restart the timing; if the controller times out when receiving the information from the host computer, it is determined that the communication is interrupted, and the original program in the backup area is written back to the main area.

[0059] Through this implementation, when the CAN communication line is poorly contacted during the update process, resulting in communication interruption or the updated program is insufficient, the normal program saved in the backup area can be rolled back, effectively improving the security and reliability of the controller update program.

[0060] In one application scenario, when the updated version of the boot program is written to the first main area, the controller runs the original boot program in the first backup area. If the timer times out, the interrupt processing function is entered to erase the data in the first main area, and then the data in the first backup area is written back to the first main area. After the write is successful, the backup area boot program flag, the boot program update flag and the boot program flash flag are set to invalid, and finally the interrupt is closed and the system is reset.

[0061] In another application scenario, when the updated application is written to the second main area, the controller runs the startup program of the first main area. If the timer times out, it enters the interrupt processing function, first erases the data in the second main area, then writes the data in the second backup area back to the second main area, sets the application update flag to invalid, and finally turns off the interrupt and performs a system reset.

[0062] In another implementation of this embodiment, after resetting to the main area to run the updated version of the program, the method further includes:

[0063] C1, detects whether a rollback program instruction is received;

[0064] C2: If a rollback program instruction is received, the data in the main area is erased, the original application program in the backup area is copied back to the main area, and a reset is performed.

[0065] After the program update is completed, if the updated program is found to have deficiencies during use, the controller can be powered on again. At this time, the controller runs the startup program of the first main area and sends a rollback program instruction through the host computer within a preset time (such as 2 seconds). After receiving the rollback program instruction, the controller performs the following corresponding operations.

[0066] If the rollback program instruction is to roll back the startup program, the parameter area run backup area startup program flag and the rollback startup program flag are set to be valid, and then jump to the first backup area to run the startup program. In the startup program, read that the run backup area startup program flag is valid, set the starting address of the interrupt vector table to the starting address of the startup program backup area, read that the rollback startup program flag is valid, erase the data in the first main area, and then write the data in the second backup area back to the first main area, and then set the run backup area startup program flag and the rollback startup program flag to invalid and reset.

[0067] If the rollback program instruction is to roll back the application program, the data in the second main area is erased, and then the data in the second backup area is written back to the second main area, and reset.

[0068] In this embodiment, if the updated program is insufficient, a rollback request can be sent through the host computer to write the original program back to the startup program main area or the application program main area, so that the controller can resume normal operation.

[0069] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present application.
