[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on January 2, 2024, with application number 202410004388.6 and invention name “A vehicle terrain mode switching method, device, equipment and medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of artificial intelligence technology, and in particular to a vehicle terrain mode switching method, device, equipment and medium. Background Art

[0004] As a means of transportation, cars provide immense convenience for people. As the use cases diversify, so too do the environments in which cars are used. Cars no longer operate solely on paved roads, but now also in complex road conditions such as mud, sand, and snow. Different terrains place varying demands on car control systems. Improving car performance requires adaptability to diverse terrains, providing a superior driving experience in diverse road conditions, and extending the life of the car.

[0005] Currently, there are all-terrain vehicle control systems that can select a driving mode for different terrain environments. Each mode can be adjusted to the corresponding road conditions to improve the vehicle's driving, braking, body stability and passing performance on various road surfaces, thereby meeting users' expectations for safe and smooth driving in various complex road conditions.

[0006] Due to the different types of terrain environments, vehicles are usually equipped with multiple terrain modes. However, the inventors found that the existing car mode switching method can only be switched by the driver using a knob. This physical button control solution has high requirements for the driver and is relatively complicated to operate the vehicle. The driver needs to accurately judge the type of terrain environment in which they are currently driving and take appropriate actions. If the driver is not familiar with the switching method or terrain, it will be difficult to make the corresponding judgment and operation, which will affect the driving experience of the vehicle and even cause vehicle failure or shorten the service life.

[0013] In an optional embodiment, the terrain recognition model adopts a 34-layer residual network structure, wherein the terrain image is input into a pre-trained terrain recognition model to output the terrain type of the vehicle's current driving environment, including: extracting the features of the terrain image through a single convolution layer and a maximum pooling layer; after parsing the features using the residual network layer structure, the features are again subjected to maximum pooling to obtain the terrain type of the vehicle's current driving environment.

[0014] In an optional embodiment, the terrain recognition model is trained by the following steps: collecting terrain images corresponding to each terrain type and annotating them to obtain sample training sets corresponding to different terrain types; using the sample training sets to train the initial terrain recognition model to obtain the terrain recognition model.

[0015] In an optional embodiment, the collecting of terrain images corresponding to each terrain type and labeling thereof include: using an experimental vehicle equipped with a camera to drive in a terrain environment corresponding to each terrain type, and controlling the experimental vehicle to be in a form mode corresponding to the terrain type; controlling the camera of the experimental vehicle to collect a terrain image at a preset period, and marking the corresponding terrain type label on the terrain image.

[0016] In the second aspect, the present application provides a vehicle terrain mode switching method and a vehicle terrain mode switching device, the device comprising: an acquisition module, for turning on the vehicle's on-board camera to acquire a terrain image of the vehicle's current driving environment when the driver does not select the physical knob switch; an identification module, for inputting the terrain image into a pre-trained terrain recognition model and outputting the terrain type of the vehicle's current driving environment; and a switching module, for controlling the vehicle to switch to a driving mode corresponding to the identified terrain type based on the identified terrain type.

[0028] The following will describe the embodiments of the present application with reference to the accompanying drawings and optional embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the optional embodiments are only for the purpose of illustrating the present application and are not intended to limit the scope of protection of the present application.

[0029] The embodiments of the present application provide a method, apparatus, device, and medium for switching vehicle terrain modes. The technical solutions provided in the embodiments of the present application are primarily applicable to automobiles (or vehicles), and are particularly applicable to vehicles equipped with cameras and multiple terrain modes. The configured camera can be used to capture images of the vehicle's front route, or it can be a device for capturing 360° images of the vehicle. It can be a built-in camera on the vehicle, or it can be a device configured elsewhere to capture images of the ground environment. There is no specific limit on the number of multiple terrain modes configured on the vehicle, and it can be three, four, or even six. In an optional embodiment, the vehicle's configured terrain modes may include six: standard mode, ice and snow mode, mud mode, pothole mode, sand mode, and wading mode. Optionally, terrain mode switching methods may include a knob switch method, a fully automatic mode switch method, and an active recommended mode switch method. When the driver selects the knob switch method, the vehicle switches modes based on the knob signal. When the driver selects the fully automatic mode switch method, the vehicle's onboard camera captures a terrain image, inputs the image into a terrain recognition model, and upon successful recognition, directly switches to the corresponding mode. When the driver chooses to actively recommend a mode switch, the vehicle's onboard camera captures a terrain image and inputs the image into a terrain recognition model. Upon successful recognition, a mode switch request is sent to the central control screen for driver confirmation. If the driver chooses to switch, the system switches to the corresponding mode. If the driver chooses not to switch, the system remains in its original state. The following describes the technical solution of the embodiment of this application in detail.

[0030] The present application provides a method for switching a vehicle terrain mode. The method is applicable to a vehicle and can be controlled by a controller on the vehicle. As shown in FIG1 , the method includes:

[0031] Step S101: If the driver does not select the physical knob switch, the vehicle's onboard camera is turned on to collect a terrain image of the vehicle's current driving environment;

[0032] As described above, the vehicle in the embodiment of the present application can support multiple terrain modes, and the terrain mode switching methods may include knob switching, fully automatic mode switching, and proactively recommended mode switching. Among them, the knob switching method has a higher priority than other modes. In other words, when the driver chooses to use the knob switching method, that is, physical knob switching, the vehicle cannot automatically switch modes. In this case, it is not within the scope of protection of this application.

[0033] The embodiment of the present application is applicable to the vehicle autonomously identifying or switching the corresponding terrain mode when the driver does not select the physical knob switch.

[0034] If the driver does not select the physical knob to switch, or the driver selects the fully automatic mode switch or the actively recommended mode switch, the vehicle is controlled to turn on the on-board camera to collect terrain images of the vehicle's current driving environment. The current driving environment is photographed so that the terrain environment currently located by the terrain image can be identified.

[0035] Step S102: input the terrain image into a pre-trained terrain recognition model, and output the terrain type of the vehicle's current driving environment.

[0036] In an embodiment of the present application, a corresponding terrain recognition model is pre-trained for terrain recognition. The terrain recognition model can adopt a neural network model. The terrain type of the current driving environment is identified by the pre-trained terrain recognition model to facilitate timely mode switching.

[0037] In the embodiment of the present application, the terrain recognition model can be deployed on the cloud. After uploading the collected terrain image to the cloud, the cloud will perform the terrain type identification. In this way, the vehicle only needs to have a camera to collect terrain images. There is no need to configure higher processing performance equipment on the vehicle, and there is even no need to change the original vehicle system. It only needs to upload the image, receive the judgment result on the cloud, and then switch or recommend switching in the vehicle system. On the other hand, in the embodiment of the present application, the terrain recognition model can also be deployed directly on the vehicle. After collecting the terrain image, the vehicle itself directly identifies the corresponding terrain type. In this way, when the vehicle is off the grid, it can autonomously identify the terrain type without being restricted by the network environment, while improving the response speed and efficiency.

[0038] Step S103 , based on the identified terrain type, controlling the vehicle to switch to a driving mode corresponding to the identified terrain type.

[0039] In the embodiment of the present application, after the terrain recognition model identifies the terrain type of the current driving environment, the driving mode can be switched based on the terrain type. In the embodiment of the present application, how to switch the driving mode can be determined based on the specific control scheme of the switching mode.

[0040] According to an embodiment of the present application, by collecting a terrain image of the vehicle's current driving environment, and then using a pre-trained terrain recognition model to identify and process the terrain image, the terrain type of the current driving environment is determined, and then the corresponding terrain type is switched. Compared with the knob switching method used in the prior art, the vehicle can autonomously switch driving modes or recommend switching. The user does not need to be familiar with the terrain environment type or the switching method, which greatly facilitates the user's operation and improves the convenience of vehicle driving. At the same time, since the terrain image of the current driving environment is directly collected and the terrain type of the vehicle is directly identified from the terrain image, compared with the solution that uses the parameters fed back by the vehicle body as the basis for judgment, the terrain type recognition is more accurate and the mode switching is more precise.

[0041] The switching scheme of the embodiment of the present application is shown in Figure 2. In the knob switching mode, no detailed introduction is given. If the vehicle is currently in full-automatic mode switching, based on the identified terrain type, the vehicle is controlled to switch to the driving mode corresponding to the identified terrain type, including: automatically controlling the vehicle to switch to the driving mode corresponding to the identified terrain model.

[0042] As mentioned above, when the driver selects fully automatic mode switching, the onboard camera captures a terrain image, feeds the image into the terrain recognition model, and upon successful recognition, directly switches to the corresponding mode. In other words, when in fully automatic mode switching, once the vehicle recognizes the terrain type of the current driving environment, it directly switches to the driving mode, achieving adaptive control switching and improving vehicle operation convenience.

[0043] On the other hand, if the vehicle is currently in an active recommended mode switch, based on the identified terrain type, the vehicle is controlled to switch to the driving mode corresponding to the identified terrain type, including: sending a mode recommendation request to the vehicle's central control screen, the mode recommendation request is used to request the driver to switch to the driving mode corresponding to the identified terrain type; responding to the driver's operating instructions to determine whether to switch the vehicle to the driving mode corresponding to the identified terrain type.

[0044] As mentioned above, when a mode switch is proactively recommended, after the terrain type is identified, the terrain type will be sent to the vehicle's central control screen via a request, prompting the user to switch to the corresponding driving mode. Typically, after receiving the reminder, the user can independently choose whether to switch, either by pressing a button on the vehicle or on the central control screen. If the user confirms the switch, the vehicle directly switches to the driving mode corresponding to the identified terrain type; otherwise, if the user decides not to switch, the current driving mode remains.

[0045] Of course, in the embodiment of the present application, if the identified terrain type is consistent with the current driving mode of the vehicle, no mode switching or mode switching reminder will be performed.

[0046] Optionally, in an embodiment of the present application, when the vehicle uses a fully automatic mode switching method or an active recommendation mode switching method, if the knob is turned to switch the state, the system will switch the state and make an active recommendation the next time a terrain change is detected.

[0047] As an optional implementation, in an embodiment of the present application, a terrain image is input into a pre-trained terrain recognition model to output the terrain type of the vehicle's current driving environment, including: obtaining multiple continuous terrain images within a preset time period; inputting the multiple terrain images into the terrain recognition model in sequence to obtain the terrain type of each terrain image within the preset time period; if the terrain type in which the vehicle is located within the preset time period is the same type, then determining that type as the terrain type of the vehicle's current driving environment.

[0048] The preset time period can be set as needed, for example, 10 seconds. In the embodiment of the present application, multiple identifications and identifications of multiple terrain images are used before determining the final terrain type. For example, when using the fully automatic switching mode and the active recommendation switching mode, the terrain recognition model detects the terrain once every 2 seconds. When the detection results are the same for 10 seconds, it indicates that the user has entered the terrain type rather than sending a switching signal due to misidentification. This improves the error tolerance rate of terrain type recognition.

[0049] As an optional implementation, the terrain recognition model of the embodiment of the present application can use a residual learning module to build a network with a higher number of layers to better learn the target features. The residual learning module is shown in Figure 3. The terrain recognition model can adopt a 34-layer residual network structure, as shown in Figure 3. Specifically, the terrain image is input into the pre-trained terrain recognition model, and the terrain type of the vehicle's current driving environment is output, including: extracting the features of the terrain image through a convolution layer and a maximum pooling layer; after parsing the features using the residual network layer structure, it is again subjected to maximum pooling to obtain the terrain type of the vehicle's current driving environment.

[0050] After the terrain image is input, features are extracted through a single convolution and maximum pooling. The number of channels in the residual module is 64, 128, 256, and 512, respectively. The convolution stride of the three-layer network is 2, doubling the number of channels to 512. Maximum pooling is performed again before output, and the image is classified into six categories based on the terrain type.

[0051] In the embodiment of the present application, a pre-built initial model is used, as shown in Figure 4, and then a training set is constructed for model training. The terrain recognition model is trained by the following steps: terrain images corresponding to each terrain type are collected and annotated to obtain sample training sets corresponding to different terrain types; the sample training sets are used to train the initial terrain recognition model to obtain a terrain recognition model. The neural network used in the terrain recognition model of the embodiment of the present application is essentially a neural network classifier. The network is trained using a large amount of terrain data samples, enabling the network to accurately classify the input terrain images.

[0052] Among them, the collection of training samples can be carried out by collecting and annotating images while the vehicle is driving. Specifically, terrain images corresponding to each terrain type are collected and annotated, including: using an experimental vehicle equipped with a camera to drive in a terrain environment corresponding to each terrain type, and controlling the experimental vehicle to be in a form mode corresponding to the terrain type; controlling the camera of the experimental vehicle to collect a terrain image every preset period, and marking the corresponding terrain type label on the terrain image.

[0053] In this example, a test vehicle drives across the terrain to collect image data. The experimenter uses a knob to select the corresponding terrain type. Each captured image is automatically labeled. After a certain number of images of each terrain type are collected, they serve as training samples for model training.

[0054] The present application also provides a vehicle terrain mode switching device, applicable to a vehicle. The device corresponds to the method shown in FIG1 , and as shown in FIG5 , the device includes:

[0055] The acquisition module 501 is configured to activate the vehicle's onboard camera to acquire a terrain image of the vehicle's current driving environment when the driver does not select the physical knob switch;

[0056] The recognition module 502 is configured to input the terrain image into a pre-trained terrain recognition model and output the terrain type of the vehicle's current driving environment;

[0057] The switching module 503 is configured to control the vehicle to switch to a driving mode corresponding to the identified terrain type based on the identified terrain type.

[0058] According to an embodiment of the present application, by collecting a terrain image of the vehicle's current driving environment, and then using a pre-trained terrain recognition model to identify and process the terrain image, the terrain type of the current driving environment is determined, and then the corresponding terrain type is switched. Compared with the knob switching method used in the prior art, the vehicle can autonomously switch driving modes or recommend switching. The user does not need to be familiar with the terrain environment type or the switching method, which greatly facilitates the user's operation and improves the convenience of vehicle driving. At the same time, since the terrain image of the current driving environment is directly collected and the terrain type of the vehicle is directly identified from the terrain image, compared with the solution that uses the parameters fed back by the vehicle body as the basis for judgment, the terrain type recognition is more accurate and the mode switching is more precise.
