Description

Driving mode switching methods, devices, vehicles, and storage media

[0001] This application claims priority to Chinese Patent Application No. 202510358404.6, filed on March 25, 2025, entitled “Method, Apparatus, Vehicle and Storage Medium for Switching Driving Modes”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of automotive technology, and in particular to a method, device, vehicle, and storage medium for switching driving modes. Background Technology

[0003] As people's living standards continue to improve, higher demands are being placed on vehicle performance and driving experience. In modern driving scenarios, vehicles need to adapt to various complex terrains and road conditions to ensure driving comfort, safety, and efficiency. To meet these diverse needs, vehicle manufacturers have developed multiple driving modes to adapt to different driving environments.

[0004] Currently, vehicles are typically equipped with multiple preset driving modes, such as Eco, Standard, Sport, Snow, Mud, Sand, and Rock modes. These modes adjust parameters such as power output, suspension system, and four-wheel drive system to adapt to different terrains and road conditions. Drivers can manually switch to the appropriate driving mode according to the actual driving scenario, thereby optimizing the vehicle's performance.

[0005] However, manually switching driving modes has a certain technical threshold. The driver's familiarity with the terrain and ability to judge road conditions directly affect the efficiency of driving mode switching. If the driver is unfamiliar with the terrain or fails to notice changes in road conditions in time, they may miss the optimal switching opportunity, causing the vehicle to be unable to provide performance matching the current road conditions, and may even lead to safety issues such as the vehicle getting stuck, thereby reducing the user's overall satisfaction with the vehicle. Summary of the Invention

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0052] In this application, the terms "first," "second," etc., are used to distinguish identical or similar items with essentially the same function. It should be understood that there is no logical or temporal dependency between "first," "second," and "n," nor is there any limitation on the quantity or execution order.

[0053] In this application, the term "at least one" means one or more, and "multiple" means two or more.

[0054] It should be noted that all information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.), and signals involved in this application are authorized by the user or fully authorized by all parties, and the collection, use, and processing of related data must comply with the relevant laws, regulations, and standards of the relevant countries and regions. For example, the driving status information, environmental information, and historical driving parameters involved in this application were all obtained with full authorization.

[0055] The driving mode switching method provided in this application can be executed by a computer device. In some embodiments, the computer device is a terminal or a server. The following describes the implementation environment of the driving mode switching method provided in this application, using a computer device as an example. Figure 1 is a schematic diagram of the implementation environment of a driving mode switching method provided in this application. Referring to Figure 1, the implementation environment includes a vehicle 101 (terminal) and a server 102. The terminal 101 and the server 102 can be directly or indirectly connected via wired or wireless communication, which is not limited herein.

[0056] In some embodiments, vehicle 101 can be a new energy vehicle, such as a pure electric vehicle, a plug-in hybrid electric vehicle, or a fuel cell electric vehicle; alternatively, vehicle 101 can also be a gasoline vehicle, and this application embodiment does not impose any limitations on this. Vehicle 101 is equipped with a vehicle controller (body domain controller), a vehicle networking system, and an integrated brake controller. The vehicle controller can communicate with the vehicle networking system and the integrated brake controller in the on-board terminal via a CAN (Controller Area Network) bus. The vehicle networking system has a communication connection with server 102 and can obtain environmental information of vehicle 101 (e.g., weather information of vehicle 101's location) from server 102. Then, the vehicle controller can determine a suitable driving mode for vehicle 101 based on the driving status information and environmental information of vehicle 101, and then instruct the integrated brake controller to distribute braking and driving forces to vehicle 101 through the driving mode, so as to switch vehicle 101 to the appropriate driving mode.

[0057] Those skilled in the art will understand that the number of terminals described above can be more or less. For example, there may be only one terminal, or there may be dozens or hundreds of terminals, or even more. This application does not limit the number of terminals or the type of device.

[0058] In some embodiments, server 102 can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network), big data, and artificial intelligence platforms. Server 102 can provide background support for vehicle 101 to switch driving modes. For example, server 102 can provide vehicle 101 with environmental information, mode triggering conditions, and mode switching conditions required for switching driving modes; this embodiment does not limit this. In some embodiments, server 102 undertakes the main computing work, and terminal 101 undertakes the secondary computing work; or, server 102 undertakes the secondary computing work, and terminal 101 undertakes the main computing work; or, server 102 and terminal 101 use a distributed computing architecture for collaborative computing.

[0059] Figure 2 is a flowchart of a driving mode switching method according to an embodiment of this application. Referring to Figure 2, this embodiment of the application illustrates the driving mode switching method performed by a vehicle as an example. The driving mode switching method includes the following steps:

[0060] 201. When the mode switching function is activated, the vehicle obtains the vehicle's driving status information and environmental information at the current moment. The environmental information includes road condition information and weather information. The road condition information is used to indicate the surface condition of the road where the vehicle is located, and the weather information is used to indicate the weather at the vehicle's location.

[0061] In this embodiment, the vehicle's driving status information may include parameters such as vehicle speed, acceleration, driving direction, vehicle position, yaw rate, pitch angle, fuel or electricity consumption, torque output, braking pressure, and tire pressure. This embodiment does not impose limitations on these parameters. When the mode switching function is activated, the vehicle acquires the current driving status information and environmental information.

[0062] Environmental information includes vehicle road condition information and weather information. This application embodiment does not limit the method of obtaining road condition information and weather information.

[0063] In some embodiments, the process of obtaining traffic information includes at least one of the following:

[0064] The first feature is the wading radar installed below the vehicle's rearview mirrors. This radar detects the depth to which the vehicle's wheels are stuck in the road. In other words, the radar provides information about the road conditions in the vertical direction, i.e., the current road conditions. For example, if the road is covered in snow, the wading depth will be the depth the vehicle is stuck in; if the road is muddy, the wading depth will be the depth the vehicle is stuck in; and if the road is flooded, the wading depth will be the depth the vehicle is stuck in the floodwater.

[0065] Secondly, the vehicle is equipped with a forward-facing camera. The vehicle uses this camera to obtain information about the road conditions ahead. This information includes at least one of the following: road surface features and traffic conditions. Road surface features may include road material (e.g., asphalt, gravel, brick), road surface smoothness, road slope, road aging and damage characteristics (e.g., cracks, ruts), speed bumps, etc., which are not limited in this embodiment. Traffic conditions may include the degree of road congestion, traffic light status, traffic signs (e.g., speed limit signs), etc., which are not limited in this embodiment.

[0066] The solution provided in this application uses wading radar to obtain the current road conditions of the vehicle and a forward-facing camera to obtain the road conditions ahead of the vehicle, enabling the acquisition of more accurate environmental information. This allows for the subsequent matching of a more suitable driving mode to the vehicle, thereby ensuring safety and comfort during driving and ultimately improving user satisfaction with the vehicle.

[0067] In some embodiments, a vehicle-to-everything (V2X) system may be installed on the vehicle. The vehicle can obtain weather information about its location through this V2X system; the method of obtaining the weather information is not limited in this application embodiment. The V2X system can be installed on the vehicle's dashboard and connected to the vehicle controller (body domain controller) via a proprietary protocol. This allows the vehicle controller to provide location information and real-time weather information, enabling it to determine the vehicle's driving mode based on the vehicle's driving status and environmental information.

[0068] In this embodiment of the application, the opening and closing of the mode switching function can be controlled by the user (e.g., the driver) or by the vehicle, and this embodiment of the application does not impose any restrictions on this.

[0069] In some embodiments, the mode switching function is user-controlled. The vehicle can display a mode switching control on its own display screen (e.g., the instrument panel) to prompt the user to confirm whether to delegate the driving mode switching task to the vehicle itself. When the mode switching control is triggered, the vehicle's mode switching function is activated. This method, where the mode switching function is user-controlled, ensures that the vehicle's driving behavior conforms to the user's intentions, i.e., meets the user's driving needs.

[0070] In other embodiments, the mode switching function is controlled by the vehicle. The vehicle activates the mode switching function when the frequency of changes in the vehicle's environment exceeds a preset frequency. Alternatively, the vehicle activates the mode switching function when the user (driver) switches driving modes more frequently than a preset frequency. This method allows the vehicle to automatically switch modes when frequent switching is required, eliminating the need for frequent manual switching by the user and improving the driving experience. Alternatively, the vehicle activates the mode switching function when the current driving mode is incompatible with the vehicle's environment. Since the driving mode is incompatible with the environment, it indicates that the user cannot select a suitable driving mode for the environment. In this case, the vehicle automatically activates the mode switching function to ensure that the driving mode matches the environment, thereby ensuring driving safety and stability.

[0071] For situations where the mode switching function is controlled by the vehicle, the vehicle can display a switching prompt message on the screen before activating the mode switching function to inform the user that the mode switching function is controlled by the vehicle itself. Furthermore, the switching prompt message can also include confirmation and cancellation controls. If the confirmation control is triggered, the vehicle activates the mode switching function; if the cancellation control is triggered, the vehicle keeps the mode switching function in the off state.

[0072] 202. The vehicle determines the target driving mode based on driving status information, environmental information, and mode triggering conditions. The mode triggering conditions are used to represent the matching relationship between the driving mode and the vehicle's driving status information and environmental information.

[0073] In this embodiment, the vehicle's driving mode may include multiple modes such as economy mode, snow mode, mud mode, and sand mode, and this embodiment does not impose any limitations on this. The mode triggering conditions include triggering conditions for various driving modes. Each driving mode triggering condition refers to the conditions that the vehicle's driving status information and environmental information must meet when switching to that driving mode. The vehicle controller on the vehicle determines the target driving mode that matches the vehicle's driving status information and environmental information from the mode triggering conditions.

[0074] For example, the trigger condition for the snow mode is receiving a snow signal and the wheels sinking less than 10 centimeters into the road; the trigger condition for the mud mode is that the wheels sinking more than 20 centimeters into the road.

[0075] 203. When the vehicle meets the mode switching conditions, the vehicle will switch its driving mode to the target driving mode. The mode switching conditions are used to indicate the vehicle status that allows the switching of driving modes.

[0076] In this embodiment, the mode switching conditions may include the vehicle's battery or fuel level not falling below a preset value, or the vehicle being in a steady-state driving condition. This embodiment does not impose any limitations on these conditions. Accordingly, the process by which the vehicle determines that it meets the mode switching conditions includes at least one of the following:

[0077] The first condition is that, provided the vehicle's battery or fuel level is not lower than a preset value at the current moment, the vehicle's driving status information meets the mode switching conditions. The preset value is the target battery or fuel level that the vehicle needs to achieve when driving in the target driving mode. In other words, before switching driving modes, the vehicle needs to determine whether the remaining battery or fuel level supports the desired driving mode. For example, in mud mode, the vehicle requires greater power output. If the vehicle's battery or fuel level is low and insufficient to support mud mode driving, the vehicle cannot switch to mud mode.

[0078] The second condition is that, given the vehicle's current steady-state driving condition, the vehicle's driving status information meets the mode switching conditions. A steady-state driving condition means that the vehicle's motion parameters (such as speed, acceleration, steering angle, roll angle, etc.) remain relatively stable, without significant fluctuations or loss of control. This state typically indicates that the vehicle is in a safe and controllable condition.

[0079] For example, if a vehicle is traveling straight on a road at a certain speed, then the vehicle's driving state is determined to be in a steady state; if the vehicle is making a sharp turn, the steering angle and roll angle will fluctuate greatly, then the vehicle's driving state is determined to be in a non-steady state.

[0080] The solution provided in this application takes into account driving factors such as vehicle battery level or fuel level and vehicle driving status before switching driving modes. Switching driving modes is only allowed when the vehicle battery level or fuel level is not lower than a preset value, thus ensuring the subsequent driving of the vehicle. Switching driving modes is only allowed when the vehicle driving status is in a steady state, thus ensuring the safety of vehicle driving.

[0081] In this embodiment, when the vehicle meets the mode switching conditions, the vehicle can automatically switch its driving mode to the target driving mode. Alternatively, before switching driving modes, the vehicle can solicit the driver's opinion, and then switch modes only if the driver gives permission. This embodiment does not limit the method by which the vehicle solicits opinion. For example, the vehicle can play a voice prompt asking whether the driver is allowed to switch to the target driving mode, and after receiving the driver's permission, switch the driving mode to the target driving mode. Alternatively, the vehicle can display a prompt on the in-vehicle display screen to ask the driver whether they are allowed to switch to the target driving mode, and after confirming the driver's permission through the prompt, switch the driving mode to the target driving mode.

[0082] Accordingly, when the vehicle meets the mode switching conditions, the vehicle displays mode switching information. This mode switching information is used to determine whether the driver allows the vehicle to switch to the target driving mode. Then, in response to a confirmation operation regarding the mode switching information, the vehicle switches its driving mode to the target driving mode. The mode switching information may include text asking whether switching to the target driving mode is allowed, a confirmation control, and a cancellation control. If the confirmation control is triggered, the vehicle switches its driving mode to the target driving mode. If the cancellation control is triggered, the vehicle retains its current driving mode. The solution provided in this application, by asking the driver's opinion before switching driving modes, ensures that the vehicle's driving state meets the driver's driving needs, thereby improving user satisfaction with the vehicle.

[0083] In other embodiments, if the display duration of the mode switching information reaches a preset duration, and the driver does not interact with the mode switching information within the preset duration, the vehicle will switch the driving mode to the target driving mode. That is, if the driver does not actively intervene in the mode switching function within the display reminder period, it is determined that the driver has received the switching request, and in this case, the driving mode is switched to the target driving mode. This method achieves driving mode switching without driver intervention, minimizing the impact on the driver's operation, ensuring safety during driving, and improving the user's driving experience.

[0084] During the process of switching the vehicle's driving mode to the target driving mode, the vehicle can directly adjust the current driving parameters to the driving parameters indicated by the target driving mode. Alternatively, the vehicle can also use a smoothing process to adjust the current driving parameters to the driving parameters indicated by the target driving mode. This application does not limit the smoothing process; for example, the smoothing process can be linear interpolation, Bézier curves, or moving averages.

[0085] The vehicle can calculate the difference between the driving parameters at the current moment and the driving parameters indicated by the target driving mode. If the difference does not reach the preset value, the vehicle can directly adjust the driving parameters at the current moment to the driving parameters indicated by the target driving mode. If the difference reaches the preset value, the vehicle will use a smooth processing method to adjust the driving parameters at the current moment to the driving parameters indicated by the target driving mode.

[0086] The solution provided in this application adopts a smooth processing method to switch driving parameters, ensuring the stability and safety of the vehicle during the driving mode switching process; moreover, the smooth processing method will only be used to switch when the difference between the driving parameters being switched reaches a preset value, and if the difference is small, the switch can be performed directly, thereby improving the efficiency of driving mode switching.

[0087] During the process of switching the vehicle's driving mode to the target driving mode, the vehicle can use the aforementioned method to switch the driving parameters to the preset driving parameters (or default driving parameters) indicated by the target driving mode. The preset driving parameters are driving parameters pre-defined by the vehicle's developers. Alternatively, the vehicle can also use the aforementioned method to switch the driving parameters to the driving parameters that the driver is accustomed to using in the target driving mode. Correspondingly, during the process of switching the vehicle's driving mode to the target driving mode, the vehicle can obtain historical driving parameters based on the driver and the target driving mode. These historical driving parameters are the driving parameters used by the driver when driving the vehicle in the target driving mode within a historical time period. Then, the vehicle adjusts the driving parameters of the vehicle at the current moment to the historical driving parameters. The solution provided in this application, by switching the driving parameters to the driving parameters that the driver is accustomed to using in the target driving mode, meets the driver's driving needs and helps improve the driver's driving experience and satisfaction.

[0088] To more clearly describe the driving mode switching method provided in this application embodiment, the driving mode switching process is further described below with reference to the accompanying drawings. For example, Figure 3 is a framework diagram of a driving mode switching method provided in this application embodiment. Referring to Figure 3, the driving mode switching system on the vehicle includes a wading radar, a forward-facing camera, a vehicle networking system, a body domain controller (i.e., a vehicle controller), a chassis domain controller, a cockpit domain controller, and an intelligent driving domain controller. The wading radar is connected to the body domain controller through a gateway, providing real-time collection and uploading of road condition data such as depth. The forward-facing camera is connected to the body domain controller through a gateway, responsible for collecting and analyzing road conditions ahead. The vehicle networking system is connected to the body domain controller through a proprietary protocol, providing vehicle location information and real-time weather information for the vehicle's location. The body domain controller processes the current road and vehicle conditions according to the mode triggering conditions, converting them into a driving mode CAN signal, wherein the driving mode indicated by the driving mode CAN signal is the target driving mode. The body domain controller sends the driving mode CAN signal to the chassis domain controller. The chassis domain controller connects to the body domain controller via a gateway. It receives driving mode information processed by the body domain controller and intelligently allocates braking and driving forces. The cockpit domain controller connects to the body domain controller via a gateway, processes the driving mode information processed by the body domain controller, and displays prompts to the driver (such as mode switching information) on the instrument panel. In other words, the chassis domain controller adjusts the performance parameters of the vehicle's chassis actuators (braking force distribution, steering assist adjustment, four-wheel power distribution, suspension performance, etc.). The intelligent driving domain controller connects to the body domain controller via a gateway, processes the driving mode information processed by the body domain controller, updates the vehicle's real-time driving status, and displays prompts to the driver on the instrument panel (such as a notification that the target driving mode has been switched).

[0089] This application does not limit the installation location of the various components in the driving mode switching system. For example, referring to Figure 4, which is a structural schematic diagram of a driving mode switching system provided according to an embodiment of this application, the wading radar 401 is installed below the exterior rearview mirror; the forward-facing camera 402 is installed above the windshield; the vehicle networking system 403 is installed on the tailgate of the vehicle; the body domain controller (i.e., the vehicle controller) 404 is installed on the top of the vehicle; the chassis domain controller 405 is installed in the vehicle chassis; the cockpit domain controller 406 is installed in the rear passenger compartment of the vehicle; and the intelligent driving domain controller 407 is installed in the driver's cabin at the front of the vehicle.

[0090] The driving mode switching method provided in this application embodiment can automatically acquire the vehicle's driving status information and environmental information at the current moment when the vehicle's mode switching function is activated. Based on the driving status information and environmental information, it determines a target driving mode that matches the vehicle's driving status and the environment in the mode triggering conditions. Then, when the vehicle meets the mode switching conditions, it switches the vehicle's driving mode to the target driving mode. Without the driver's own judgment and manual adjustment, it can directly switch the vehicle's driving mode to the target driving mode that matches the driving status and the environment, improving the efficiency of driving mode switching. Furthermore, the switched driving mode matches the vehicle's driving performance and the current road conditions, ensuring safety and comfort during driving, thereby improving user satisfaction with the vehicle.

[0091] Figure 5 is a block diagram of a driving mode switching device according to an embodiment of this application. This driving mode switching device is used to perform the steps in the driving mode switching method described above. Referring to Figure 5, the driving mode switching device includes:

[0092] The acquisition module 501 is used to acquire the vehicle's driving status information and environmental information at the current moment when the mode switching function is activated. The environmental information includes road condition information and weather information. The road condition information is used to indicate the surface condition of the road where the vehicle is located, and the weather information is used to indicate the weather at the vehicle's location.

[0093] The first determining module 502 is used to determine the target driving mode based on driving status information, environmental information and mode triggering conditions.
