[0002] Currently, the vehicle configuration can distinguish between a panoramic reverse image camera and a simple reverse image camera, but it is impossible to distinguish the camera types in the configuration of a simple reverse image camera. Therefore, the current industry practice is that the camera corresponds one-to-one with the vehicle head unit hardware and software; when changing the camera type (manufacturer), both the vehicle head unit hardware and the vehicle head unit software need to be changed. The updated vehicle head unit software cannot be used on the sold vehicles, and the vehicle head unit needs to maintain multiple software versions, resulting in a relatively high complexity of software management and thus a high management cost; and in the SOC boot startup program A stage of the existing reverse image system, when obtaining the vehicle head unit hardware version number, there will be a situation where the time to obtain the vehicle head unit hardware version number is later than the initialization time point of the camera, causing the camera initialization to fail, resulting in faults such as no reverse image on the display screen, slow image output or no image output, and thus leading to a decline in the competitiveness of vehicle products.

[0003] Therefore, there is an urgent need for a reverse image control method that can effectively reduce the diversity of controller software, lower the management cost and enhance the competitiveness of vehicle products. Summary of the Invention

[0045] The realization, functional features and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0046] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0047] The embodiment of the present invention provides a reverse image control method, referring to Figure 1 , Figure 1 Schematic flowchart of the first embodiment of the reverse image control method of the present invention.

[0048] In this embodiment, the reverse image control method is applied to a reverse image system, and the method includes steps S10 to S30:

[0049] Step S10: In the uboot stage of the SOC boot startup program in the reverse image system, obtain the target vehicle machine hardware version number stored in the MCU through the FCI protocol.

[0050] It should be noted that the execution subject of this embodiment can be a reverse image system with data processing, network communication and program running functions in the field of automotive intelligent networked intelligent control. Hereinafter, the reverse image system (referred to as the system) is taken as an example to illustrate this embodiment and the following embodiments.

[0051] For example, refer to Figure 2 , Figure 2This is a schematic diagram of the hardware of the reverse camera system in the reverse camera control method of the present invention. In the figure, the reverse camera system consists of a car head unit, a camera, a display screen, and a CAN network. The CAN network sends the vehicle reverse CAN signal to the car head unit. In a specific implementation, the car head unit can start the reverse camera program, receive the image transmitted by the camera, and at the same time call out the reverse camera auxiliary line, which is displayed on the display screen together.

[0052] It should be explained that the SOC boot startup program can be a program for system startup, including three stages: boot, A (application processor), and uboot (bootloader).

[0053] It should be noted that in the uboot stage of the SOC boot startup program, the hardware version number of the car head unit is obtained through the FCI protocol. The uboot will be completed before boot, which can ensure that the hardware version number of the car head unit has been obtained before the start of boot, thereby ensuring the correct initialization of the camera.

[0054] It should be understood that the hardware version number of the car head unit refers to the hardware version identifier of the in-vehicle infotainment system (also known as the car head unit system) built into the vehicle.

[0055] It should be explained that the FCI protocol can be the basis for functions related to the configuration of the car head unit. For example, whether to configure vehicle welcome lighting, whether to configure function switch buttons such as automatic following, etc.

[0056] In order to reduce the diversity of controller software and lower the management cost, in this embodiment, for different cameras, the car head unit is corresponding to them through the hardware version number. The car head unit software establishes multiple camera initialization parameters and reverse camera auxiliary line atlases corresponding to the hardware version number of the car head unit respectively. For example, refer to Figure 3 , Figure 3 This is a schematic diagram of the hardware and software building methods of the car head unit of the present invention adapting to multiple cameras. In the figure, different cameras (for example, Camera A, Camera B, Camera C, etc.) correspond to the hardware version numbers of the car head unit in the car head unit hardware (for example, Hardware Version Number 1 of the car head unit, Hardware Version Number 2 of the car head unit, Hardware Version Number 3 of the car head unit, etc.); multiple camera initialization parameters and reverse camera auxiliary line atlases in the car head unit software (for example, Initialization Parameters of Camera A and Auxiliary Line I of the Reverse Camera, etc.) correspond to the hardware version numbers of the car head unit in the car head unit hardware respectively.

[0057] It should be noted that the hardware version number of the car head unit is placed in the FCI (Functional Configuration Identification) protocol (this protocol is the basis for functions related to the configuration of the car head unit, such as whether to configure vehicle welcome lighting, whether to configure function switch buttons such as automatic following, etc.) as a judgment condition. The FCI item of the camera type is added to the FCI protocol, and this FCI can be configured according to the hardware version number of the car head unit.

[0058] Step S20: When the target in-vehicle hardware version number is obtained, feedback the target in-vehicle hardware version number to the boot program of the SOC boot startup program.

[0059] It should be noted that when the target in-vehicle hardware version number is obtained, the target in-vehicle hardware version number is compared with the initial in-vehicle version number in the FCI protocol to obtain a comparison result; if the comparison result indicates that the target in-vehicle hardware version number is the initial in-vehicle version number, then call the initial in-vehicle version number to the boot program of the SOC boot startup program; if the comparison result indicates that the target in-vehicle hardware version number is not the initial in-vehicle version number, then feedback the target in-vehicle hardware version number to the boot program of the SOC boot startup program.

[0060] For example, the initial setting of the in-vehicle hardware version number in the FCI protocol is version 1 (i.e., the initial in-vehicle version number). During the initialization process of the vehicle, if the obtained in-vehicle hardware version number (i.e., the target in-vehicle hardware version number) is version 1, keep the default setting of the in-vehicle version number as 1 unchanged; if the obtained in-vehicle version number is version 2 (3…), change the default setting of the in-vehicle version number to version 2 (3…).

[0061] Step S30: Determine the type of camera corresponding to the target in-vehicle hardware version number according to the FCI protocol, send a corresponding camera initialization instruction based on the type of camera through the boot program, and control the display screen to enter the reverse image display interface.

[0062] It should be noted that in this embodiment, for different cameras, the vehicle is corresponded with them through the hardware version number. The vehicle software establishes multiple camera initialization parameters and reverse image auxiliary line atlases corresponding to the in-vehicle hardware version number respectively, and adds their corresponding relationships to the FCI protocol.

[0063] Furthermore, in the specific implementation, the type of camera corresponding to the target in-vehicle hardware version number can be determined according to the corresponding relationship in the FCI protocol, and the camera initialization parameters and reverse image auxiliary line atlas corresponding to the target in-vehicle hardware version number can be determined; then, a corresponding camera initialization instruction is sent based on the camera initialization parameters corresponding to the target in-vehicle hardware version number and the type of camera to complete the camera initialization; configure the reverse image display interface based on the reverse image auxiliary line atlas corresponding to the target in-vehicle hardware version number, and control the display screen to enter the reverse image display interface.

[0064] It should be understood that in this embodiment, by identifying the version number of the in-vehicle computer hardware equipped on the vehicle, the corresponding camera initialization instruction is timely and correctly retrieved and sent to the camera, so that the camera is started and initialized, reducing the diversity of controller software and lowering the management cost.

[0065] For example, referring to Figure 4 , Figure 4 is the timing diagram for the software of the present invention to obtain the hardware version number. The figure shows the interaction process between the SOC (System on Chip) and the MCU (Microcontroller Unit) during a system startup (SOC boot). The SOC boot startup program includes three stages: boot, A (application processor), and uboot (bootloader). In the prior art, the in-vehicle computer hardware version number is obtained in the A stage of the SOC boot startup program, and there may be a situation where the time to obtain the in-vehicle computer hardware version number is later than the initialization time point of the camera, thereby causing the camera initialization to fail (such as Figure 4 at the mark ②). In this embodiment, the in-vehicle computer hardware version number is obtained through the FCI protocol in the uboot stage of the SOC boot startup program. The uboot will be completed before the boot, which can ensure that the in-vehicle computer hardware version number has been obtained before the in-vehicle computer boot starts, thereby ensuring the correct initialization of the camera (such as Figure 4 at the mark ①).

[0066] It should be explained that the uboot stage is the start stage of the entire SOC boot program, guiding the startup of the entire boot program. After the uboot starts, the in-vehicle computer hardware version number stored in the MCU is obtained through the FCI protocol; if the FCI fails to obtain the hardware version number, it will continue to try, and multiple loops can be set; if successful, it will be fed back to the boot program; if failed, the default in-vehicle computer version number in the FCI protocol will be called to the boot program; the boot program issues a preset camera initialization instruction according to the camera type matched by the FCI protocol to complete the camera initialization; at the same time, the in-vehicle computer HMI interface configures the reverse image display interface of the corresponding camera.

[0067] In the uboot stage of the SOC boot startup program in the reverse camera system of this embodiment, the target vehicle head unit hardware version number stored in the MCU is obtained through the FCI protocol; when the target vehicle head unit hardware version number is obtained, the target vehicle head unit hardware version number is fed back to the boot program of the SOC boot startup program; according to the FCI protocol, the camera type corresponding to the target vehicle head unit hardware version number is determined, and the corresponding camera initialization instruction is sent through the boot program based on the camera type, and the display screen is controlled to enter the reverse camera display interface. Since in the uboot stage of the SOC boot startup program in this embodiment, the target vehicle head unit hardware version number is obtained through the FCI protocol, the camera type corresponding to the target vehicle head unit hardware version number is determined, and the corresponding camera initialization instruction is sent through the boot program based on the camera type. Compared with the prior art, in this embodiment, by adjusting the initialization timing of the camera and the management of camera diversity, not only the diversity of the controller software is reduced, the management cost is lowered, but also the correct initialization of the camera is ensured, thereby enhancing the competitiveness of the vehicle product.

[0068] Reference Figure 5 , Figure 5 is a schematic flowchart of the second embodiment of the reverse camera control method of the present invention.

[0069] Based on the above first embodiment, in this embodiment, after the step S10, the steps S121 to S124 are further included:

[0070] Step S121: If the target vehicle head unit hardware version number is not obtained by the FCI protocol, continue to execute the step of obtaining the target vehicle head unit hardware version number stored in the MCU through the FCI protocol until the number of times of obtaining the target vehicle head unit hardware version number exceeds a preset acquisition threshold or the target vehicle head unit hardware version number is obtained.

[0071] Step S122: When the number of times of obtaining the target vehicle head unit hardware version number exceeds the preset acquisition threshold, it means that the acquisition of the target vehicle head unit hardware version number fails.

[0072] Step S123: Feed back the initial vehicle head unit version number in the FCI protocol to the boot program of the SOC boot startup program.

[0073] Step S124: Determine the camera type corresponding to the initial vehicle head unit version number according to the FCI protocol, send the corresponding camera initialization instruction through the boot program based on the camera type, and control the display screen to enter the reverse camera display interface.

[0074] It should be noted that the above preset acquisition threshold can be a custom - set value, and this embodiment and the following embodiments do not limit it. For example, if the acquisition of the FCI hardware version number fails, it will continue to try, and a total of 9 loops are set (that is, the preset acquisition threshold is equal to 9); if successful, it will be fed back to the boot program; if it fails, the default in - vehicle unit version number in the FCI protocol will be called and given to the boot program.

[0075] In a specific implementation, after step S121, it may further include: when the number of times of acquiring the target in - vehicle unit hardware version number does not exceed the preset acquisition threshold and the target in - vehicle unit hardware version number is acquired, the step of feeding back the target in - vehicle unit hardware version number to the boot program of the SOC boot startup program can be executed.

[0076] This embodiment discloses that in the uboot stage of the SOC boot startup program in a reverse - image system, the target in - vehicle unit hardware version number stored in the MCU is acquired through the FCI protocol; if the target in - vehicle unit hardware version number is not acquired by the FCI protocol, the step of acquiring the target in - vehicle unit hardware version number stored in the MCU through the FCI protocol is continued until the number of times of acquiring the target in - vehicle unit hardware version number exceeds the preset acquisition threshold or the target in - vehicle unit hardware version number is acquired; when the number of times of acquiring the target in - vehicle unit hardware version number exceeds the preset acquisition threshold, it means that the acquisition of the target in - vehicle unit hardware version number fails; the initial in - vehicle unit version number in the FCI protocol is fed back to the boot program of the SOC boot startup program; the camera type corresponding to the initial in - vehicle unit version number is determined according to the FCI protocol, and the corresponding camera initialization instruction is sent through the boot program based on the camera type, and the display screen is controlled to enter the reverse - image display interface. Compared with the prior art, in this embodiment, when the FCI protocol does not acquire the target in - vehicle unit hardware version number, the step of acquiring the target in - vehicle unit hardware version number stored in the MCU through the FCI protocol is continued until the number of times of acquiring the target in - vehicle unit hardware version number exceeds the preset acquisition threshold or the target in - vehicle unit hardware version number is acquired. Compared with the prior art, this embodiment improves the stability and security of the system, and thus enhances the competitiveness of vehicle products.

[0077] Reference Figure 6 , Figure 6 is a schematic flow chart of the third embodiment of the emergency energy management method for new - energy vehicles of the present invention.

[0078] Based on the above - mentioned embodiments, in this embodiment, before step S10, steps S01 - S04 are further included:

[0079] Step S01: Acquire multiple camera types, in - vehicle unit hardware version numbers, camera initialization parameters, and reverse - image auxiliary line atlases.

[0080] Step S02: Establish a first mapping relationship according to each of the in-vehicle unit hardware version numbers and each of the camera types.

[0081] Step S03: Establish a second mapping relationship according to each of the in-vehicle unit hardware version numbers, each of the camera initialization parameters, and each of the reverse image assist line map sets.

[0082] Step S04: Add the first mapping relationship and the second mapping relationship to the FCI protocol.

[0083] Correspondingly, in a specific implementation, step S30 may include: determining the camera type corresponding to the target in-vehicle unit hardware version number according to the first mapping relationship in the FCI protocol; determining the camera initialization parameters and the reverse image assist line map set corresponding to the target in-vehicle unit hardware version number according to the second mapping relationship in the FCI protocol; sending a corresponding camera initialization instruction based on the camera initialization parameters corresponding to the target in-vehicle unit hardware version number and the camera type to complete camera initialization; configuring a reverse image display interface based on the reverse image assist line map set corresponding to the target in-vehicle unit hardware version number, and controlling the display screen to enter the reverse image display interface.

[0084] This embodiment discloses obtaining multiple camera types, in-vehicle unit hardware version numbers, camera initialization parameters, and reverse image assist line map sets; establishing a first mapping relationship according to each of the in-vehicle unit hardware version numbers and each of the camera types; establishing a second mapping relationship according to each of the in-vehicle unit hardware version numbers, each of the camera initialization parameters, and each of the reverse image assist line map sets; adding the first mapping relationship and the second mapping relationship to the FCI protocol. Compared with the prior art, in this embodiment, by establishing mapping relationships between the in-vehicle unit hardware version number and the camera type, the in-vehicle unit hardware version number and the camera initialization parameters, and the reverse image assist line map set, etc., by identifying the in-vehicle unit hardware version number equipped on the vehicle, the corresponding camera initialization instruction can be timely and correctly retrieved and sent to the camera, so that the camera can be started and initialized, thereby reducing the diversity of controller software and lowering the management cost.

[0085] In addition, an embodiment of the present invention further provides a storage medium, on which a reverse image control program is stored, and when the reverse image control program is executed by a processor, the steps of the reverse image control method as described above are implemented.

[0086] Refer to Figure 7 , Figure 7 which is the structural block diagram of the first embodiment of the reverse image control device of the present invention.

The device includes: an information acquisition module 701, an information feedback module 702, and an image control module 703.

[0088] The information acquisition module 701 is configured to obtain the target vehicle head unit hardware version number stored in the MCU through the FCI protocol during the uboot stage of the SOC boot startup program in the reverse image system.

[0091] The information acquisition module 701 is further configured to, when the target vehicle head unit hardware version number is obtained, compare the target vehicle head unit hardware version number with the initial vehicle head unit version number in the FCI protocol to obtain a comparison result; if the comparison result indicates that the target vehicle head unit hardware version number is the initial vehicle head unit version number, then call the initial vehicle head unit version number to the boot program of the SOC boot startup program; if the comparison result indicates that the target vehicle head unit hardware version number is not the initial vehicle head unit version number, then feedback the target vehicle head unit hardware version number to the boot program of the SOC boot startup program.

[0092] In an embodiment of the present device, in the uboot stage of the SOC boot startup program in the reverse camera system, the target vehicle head unit hardware version number stored in the MCU is obtained through the FCI protocol; when the target vehicle head unit hardware version number is obtained, the target vehicle head unit hardware version number is fed back to the boot program of the SOC boot startup program; according to the FCI protocol, the camera type corresponding to the target vehicle head unit hardware version number is determined, and the corresponding camera initialization instruction is sent by the boot program based on the camera type, and the display screen is controlled to enter the reverse camera display interface. Since in the uboot stage of the SOC boot startup program in the embodiment of the present device, the target vehicle head unit hardware version number is obtained through the FCI protocol, the camera type corresponding to the target vehicle head unit hardware version number is determined, and the corresponding camera initialization instruction is sent by the boot program based on the camera type, compared with the prior art, in the embodiment of the present device, by adjusting the camera initialization timing and the management of camera diversity, not only the diversity of the controller software is reduced, the management cost is lowered, but also the correct initialization of the camera is ensured, thereby enhancing the competitiveness of the vehicle product.
