[0028] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0030] Figure 1 is a schematic diagram of an exemplary implementation of a firmware update method for a vehicle-mounted camera shown in the present application, such as Figure 1 As shown, the firmware update method of the vehicle-mounted camera includes the following steps:

[0031] S101, obtaining a camera on a target vehicle for which firmware update is to be performed as a target camera, and lighting up the target camera.

[0032] This application is mainly applicable to the firmware update of vehicle-mounted cameras, which include the cameras corresponding to the driving recorder, the driving assistance system, the reversing imaging system and the blind spot monitoring system.

[0033] This application can be executed by an autonomous driving chip (System-on-a-Chip, SOC), where the autonomous driving chip is an integrated circuit chip specifically used to support autonomous driving functions. It integrates multiple functional modules such as processors, image processing units, sensor interfaces, and communication interfaces to meet the computing power and data processing requirements of the autonomous driving system.

[0034] Among them, after determining the camera on the target vehicle to be updated with firmware as the target camera, the driver layer interface of the target camera is obtained, and the corresponding command or function of the driver layer interface is called to light up the target camera to activate the camera and make it available.

[0035] S102, determining the I2C address of the target camera, and sending an unlock instruction to the I2C address.

[0036] Each I2C device has a unique address. In this application, the I2C address of the target camera is determined, and an unlock command is sent to the I2C address to establish contact with the target camera and set the firmware memory writable permission.

[0037] Optionally, the I2C address of the target camera can be obtained from the device specification, documentation or related resources.

[0038] S103, after the target camera is unlocked, writing the target firmware file into the target camera.

[0039] Figure 2 This is a camera firmware update framework diagram shown in this application, such as Figure 2 As shown, the autonomous driving chip communicates with the target camera via I2C. After the target camera is unlocked, the autonomous driving chip writes the obtained target firmware file into the target camera based on the I2C interface.

[0040] S104, after the target firmware file is written, a lock instruction is sent to the I2C address of the target camera.

[0041] After the target firmware file is written to the camera firmware storage of the target camera, a lock instruction is sent to the I2C address of the target camera to complete the camera firmware update operation.

[0042] The embodiment of the present application realizes online firmware upgrade of the vehicle-mounted camera, eliminating the step of removing the camera from the vehicle, saving time and labor costs, and avoiding the problem of line damage that may be caused by frequent installation and removal of the camera. It is faster and more convenient, provides a better user experience, and improves the reliability and stability of operation.

[0043] Furthermore, if there are multiple vehicle-mounted cameras that need to be updated, that is, there are multiple target cameras, the target firmware files corresponding to each of the multiple target cameras are obtained. For any target camera, after the firmware update of the target camera is completed, the firmware update is performed on the next target camera based on the target firmware file corresponding to the next target camera until the firmware update of all target cameras is completed, so as to ensure that each camera is correctly updated to the latest firmware version.

[0044] Figure 3 is a schematic diagram of an exemplary implementation of another method for updating the firmware of a vehicle-mounted camera shown in the present application, such as Figure 3 As shown, the firmware update method of the vehicle-mounted camera includes the following steps:

[0045] S301, obtaining a camera on a target vehicle for which firmware update is to be performed as a target camera, and lighting up the target camera.

[0046] S302, determine the I2C address of the target camera, and send an unlock instruction to the I2C address.

[0047] For the specific implementation steps of steps S301 to S302, reference may be made to the specific introduction of the relevant parts in the above embodiment, which will not be described again here.

[0048] S303, after the target camera is unlocked, initialize the storage offset corresponding to the target camera, wherein the storage offset refers to an address offset specified in the memory, which is used to determine the location of the data in the memory.

[0049] Exemplarily, in the present application, the camera firmware storage offset is initialized, that is, param_addr is set to 0x00000000, which is equivalent to the starting address of the firmware storage.

[0050] S304: Divide the target firmware file into a plurality of sub-firmware files, and determine a single offset value according to the sub-firmware files.

[0051] Divide the target firmware file into multiple sub-firmware files. For example, each sub-firmware file can be 256 bytes, that is, the single offset value is 256 bytes. It should be noted that the size of each sub-firmware file block should be tested according to the camera and system. Too large or too small may cause flashing failure.

[0052] Among them, in this application, the method for obtaining the target firmware file is: sending a firmware file call instruction to the cloud, the firmware file call instruction carries firmware file identification information, the firmware file identification information is used by the cloud to determine the target firmware file from multiple candidate firmware files, and receive the target firmware file sent by the cloud.

[0053] S305, based on the I2C interface corresponding to the target camera, starting from the storage offset, multiple sub-firmware files are sequentially written into the target camera, wherein after any sub-firmware file is written into the target camera, the storage offset is updated based on the single offset value.

[0054] In this application, based on the I2C interface corresponding to the target camera, each sub-firmware file is written into the target camera in sequence starting from the storage offset.

[0055] Among them, since it usually takes a certain amount of time to complete the flashing of the firmware, in this application, for any sub-firmware file, after the sub-firmware file is written, the target camera is monitored for the duration, and after the target camera is monitored to wait for the preset duration, the next sub-firmware file is written to the target camera until all sub-firmware files are written. Exemplarily, the preset waiting duration can be set to 500 milliseconds.

[0056] After any sub-firmware file is written to the target camera, the storage offset is updated based on the single offset value, and the storage offset is set: param_addr + = static_cast <int>(0x0100). In this way, each time a sub-firmware file is written, the storage offset (param_addr) is increased by 0x0100 (i.e., 256, the size of the block) so as to gradually update the entire firmware content.

[0057] S306, after the target firmware file is written, a lock instruction is sent to the I2C address of the target camera.

[0058] After the target firmware file is written to the camera firmware storage of the target camera, a lock instruction is sent to the I2C address of the target camera to complete the camera firmware update operation.

[0059] The embodiment of the present application writes the target firmware file to the camera firmware storage through the I2C interface, and at the same time, by setting the storage offset, ensures that each write is correctly located at the corresponding position, so as to realize the block-by-block update and cumulative update of the firmware storage area, ensure the integrity of the new firmware, and after writing the firmware content, the next step of writing is performed after a preset time to ensure that the camera firmware storage completes the flash update. The setting of the waiting time can be adjusted according to the specific situation to ensure the stability and reliability of the firmware update. After the firmware content is written to the camera firmware storage, the camera firmware is locked through the I2C interface to ensure that the firmware will not be accidentally modified. This can enhance the security of the firmware and prevent unauthorized access and tampering.

[0060] Figure 4 is an overall diagram of another exemplary implementation of a method for updating the firmware of a vehicle-mounted camera shown in the present application, such as Figure 4 As shown, the firmware update method of the vehicle-mounted camera includes the following steps:

[0061] S401, obtaining a camera on a target vehicle for which firmware update is to be performed as a target camera, and lighting up the target camera.

[0062] S402, sending a firmware file calling instruction to the cloud, where the firmware file calling instruction carries firmware file identification information, and the firmware file identification information is used by the cloud to determine a target firmware file from multiple candidate firmware files.

[0063] S403, receiving the target firmware file sent by the cloud.

[0064] Regarding the specific implementation steps of steps S401 to S403, reference may be made to the specific introduction of the relevant parts in the above embodiment, which will not be described again here.

[0065] S404, determine the I2C address of the target camera, and send an unlock instruction to the I2C address.

[0066] S405, after the target camera is unlocked, initialize the storage offset corresponding to the target camera, wherein the storage offset refers to an address offset specified in the memory, which is used to determine the location of the data in the memory.

[0067] S406: Divide the target firmware file into a plurality of sub-firmware files, and determine a single offset value according to the sub-firmware files.

[0068] S407 , based on the I2C interface corresponding to the target camera, starting from the storage offset, for any sub-firmware file, after the sub-firmware file is written, perform duration monitoring on the target camera.

[0069] S408, after monitoring that the target camera has waited for a preset time, write the next sub-firmware file to the target camera until all sub-firmware files are written, wherein after any sub-firmware file is written to the target camera, update the stored offset based on the single offset value.

[0070] S409, after the target firmware file is written, a lock instruction is sent to the I2C address of the target camera.

[0071] Regarding the specific implementation steps of steps S404 to S409, reference may be made to the detailed introduction of the relevant parts in the above embodiment, which will not be described again here.

[0072] The embodiment of the present application writes the target firmware file to the camera firmware storage through the I2C interface, and at the same time, by setting the storage offset, ensures that each write is correctly located at the corresponding position, so as to realize the block-by-block update and cumulative update of the firmware storage area, ensure the integrity of the new firmware, and after writing the firmware content, the next step of writing is performed after a preset time to ensure that the camera firmware storage completes the flash update. The setting of the waiting time can be adjusted according to the specific situation to ensure the stability and reliability of the firmware update. After the firmware content is written to the camera firmware storage, the camera firmware is locked through the I2C interface to ensure that the firmware will not be accidentally modified. This can enhance the security of the firmware and prevent unauthorized access and tampering.
