Description

Technical Field

[0002] The statements in this part merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] With the reduction of the off-road threshold, more and more novices have joined. During the off-road process, the environment is harsh and the risk factor is high, which requires relatively high driving experience and operation level of the driver. At the same time, the control requirements for various vehicle functions are also relatively strict. In case of improper operation, it may lead to vehicle failure and loss of power at best, or even accidents at worst. For this reason, the all-terrain mode has emerged, and the popularity of the all-terrain mode benefits from the highly developed off-road market.

[0004] During the off-road process, due to the changing surrounding environment and complex road conditions, it is often difficult for users to accurately judge and respond to various situations. However, the existing all-terrain mode still cannot well meet the off-road driving needs of users. In view of the above defects, the present invention has made improvements. Summary of the Invention

By identifying the environment by the vehicle (i.e., the IHU determines the current road surface environment according to the real-time detection information) and automatically switching the driving mode in combination with the user's driving habits (i.e., the IHU automatically switches to the best driving mode according to the determination result and sends the driving mode signal corresponding to the best driving mode for vehicle control), a better driving experience can be given to the user, and the off-road driving needs of the user can be better met;

[0052] Other features and advantages of the present invention will be described in the following specification, and, in part, will be obvious from the specification, or will be understood by implementing the present invention. The objectives and other advantages of the present invention can be realized and obtained by the structures pointed out in the specification, the claims, and the drawings.

[0053] The present invention will be further described below with reference to the accompanying drawings. Description of the Drawings

[0054] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0056] Figure 2 It is a schematic logic diagram of a method for identifying the environment and automatically switching the driving mode for vehicle control according to an embodiment of the present invention;

[0057] Figure 3 It is a schematic structural diagram of an electronic device according to an embodiment of the present invention. Detailed implementation manners

[0058] To make the purpose, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0059] As Figure 1 shown, an embodiment of the present invention provides a control method for an intelligent driving mode. The method includes the following steps:

[0060] S1. After receiving the command to adjust the driving mode to the intelligent driving mode, the intelligent host unit IHU enters the all-terrain intelligent control multi-mode system, synchronously switches the central control display screen interface, and gives a mode reminder;

[0061] S2. The intelligent host unit IHU detects and adjusts the status of the associated items of the all-terrain intelligent control multi-mode system. The status of the associated items of the all-terrain intelligent control multi-mode system includes the status of the wading radar and the associated status of the electric power steering system EPS and the all-terrain intelligent control multi-mode system;

[0062] S3. The intelligent host unit IHU determines the current road surface environment according to the real-time detection information;

[0063] S4. According to the determination result of the current road surface environment, the intelligent host unit IHU controls the all-terrain intelligent control multi-mode system to automatically switch to the best driving mode and sends the corresponding driving mode signal for vehicle control.

[0064] In the above technical solution, when the intelligent host unit IHU enters the all-terrain intelligent control multi-mode system, the vehicle enters the intelligent driving mode (also known as the all-terrain mode). Switching the central control display screen interface facilitates the user to operate the all-terrain intelligent control multi-mode system. Providing mode reminders can clearly inform the user that the vehicle has entered the intelligent driving mode. The IHU detects and adjusts the status of the items associated with the all-terrain intelligent control multi-mode system, which facilitates the better operation of the all-terrain intelligent control multi-mode system in the next step to achieve the intelligent driving mode. The above solution adopts the all-terrain intelligent control multi-mode system, which can perform intelligent adjustment and intervention. By the vehicle identifying the environment (i.e., the IHU determines the current road surface environment based on real-time detection information) and automatically switching the driving mode in combination with the user's driving habits (i.e., the IHU automatically switches to the best driving mode according to the determination result and sends the driving mode signal corresponding to the best driving mode for vehicle control), it can provide a better driving experience for the user and better meet the user's off-road driving needs.

[0065] During specific implementation, the user can turn on the intelligent driving mode with one click by pressing the intelligent driving mode button. When the user presses this button, the intelligent host unit IHU receives the command to adjust the driving mode to the intelligent driving mode, and thus enters the all-terrain intelligent control multi-mode system.

[0066] In this embodiment, the intelligent host unit IHU detects and adjusts the status of the items associated with the all-terrain intelligent control multi-mode system, which includes detecting and adjusting the status of the wading radar (DepthWading Detection, DWD) and detecting and adjusting the associated status of the electric power steering system EPS and the all-terrain intelligent control multi-mode system. The following will be described separately.

[0067] As a preferred technical solution, the intelligent host unit IHU detects and adjusts the status of the wading radar, including: the intelligent host unit IHU detects the status of the wading radar and memorizes it; if the wading radar is turned on, the soft switch of the wading radar is set to the inoperable state; if the wading radar is not turned on, the wading radar is automatically turned on, and the soft switch of the wading radar is set to the inoperable state; if the user clicks to turn off the wading radar, a prompt will be given: the wading radar cannot be turned off in the current mode.

[0068] In this embodiment, the IHU determines the status of the wading radar associated with the all-terrain intelligent control multi-mode system and memorizes it (memorization means storing the current status of the wading radar and the real-time change of the memorization depth, which can be used to judge the boundary conditions under various off-road environment judgment logics set later). The wading radar is turned on and the corresponding soft switch should be in an inoperable state to prevent the lack of road condition judgment conditions after the user manually turns it off. Specifically, the IHU detects the status of the wading radar and memorizes it. The wading depth and snow depth are identified through the wading radar, and the wading radar can identify depths from 0 cm to 100 cm. If the wading radar is not turned on, the wading radar is automatically turned on, and the soft switch of the wading radar is set to an inoperable state to prevent the user from misoperating. If the user clicks to turn it off, a prompt of "Cannot be turned off in the current mode" will be given. In this embodiment, the main function of the wading radar is to detect the road surface depth to determine whether the vehicle is wading / snowing. For this solution, after the IHU enters the all-terrain intelligent control multi-mode system, the wading radar must be in an on state because the wading signal is required for the subsequent mode switching judgment conditions. Therefore, the wading radar needs to be turned on and cannot be turned off.

[0069] As a preferred technical solution, the intelligent host unit IHU detects and adjusts the association status between the electric power steering system EPS and the all-terrain intelligent control multi-mode system, including: the intelligent host unit IHU detects the association status between the electric power steering system EPS and the all-terrain intelligent control multi-mode system; if they are associated, an EPS-OFF command is issued, the EPS assist mode is set to comfort, and the EPS soft switch is set to an inoperable state; if they are not associated, the current EPS assist mode is maintained.

[0070] In this embodiment, the IHU detects the association status between the electric power steering system (EPS) and the all-terrain intelligent control multi-mode system. If EPS is associated with the all-terrain intelligent control multi-mode system, an EPS-OFF command is issued through the large screen (i.e., the central control display screen), the EPS assist mode is set to "comfort", and the EPS soft switch is set to an inoperable state, which can prevent the user from misassociating EPS with the all-terrain intelligent control multi-mode system again. Because when driving on multi-terrain road conditions, after the driving mode (i.e., the all-terrain intelligent control multi-mode system) is associated with the steering (EPS), the steering force changes greatly, which will bring a bad driving experience. In this embodiment, after exiting the all-terrain intelligent control multi-mode, EPS is associated with each driving mode again (for example: the economy mode corresponds to the lightness of EPS, and the sport mode corresponds to the sportiness of EPS). If EPS is not associated with the all-terrain intelligent control multi-mode system, the current assist mode remains unchanged.

[0071] During specific implementation, the user can set whether EPS is associated with the all-terrain intelligent control multi-mode system through a large screen. The purpose of not associating this solution is to avoid large steering force changes in the intelligent driving mode.

[0072] As a preferred technical solution, the real-time detection information includes road condition data and vehicle data; the road condition data includes wading radar signals, slopes, snow signals, infrared recognition signals, and rain signals; the vehicle data includes vehicle speed and throttle opening.

[0073] In this embodiment, the IHU determines the current road surface environment based on wading radar signals, snow signals, throttle opening, vehicle speed, and duration, etc. Specifically, the IHU comprehensively analyzes wading radar signals, snow signals (the front-view camera captures images, through camera self-learning, identifies snow through ruts, shapes, etc. and emits snow signals, that is, after being processed by intelligent algorithms to identify snow-covered road surface characteristics), throttle opening (the throttle opening comes from the engine control unit, is sent by the throttle pedal, and the throttle opening signal processed by the VCU will be sent to the EMS), vehicle speed, and the calibrated duration for different vehicle models under various road conditions (the duration and opening signal of the throttle are detected by the throttle pedal position sensor and processed by the vehicle's electronic control unit) and other aspects of data (i.e., real-time detection information), and determines the current road surface environment in real time, as Figure 2 shown.

[0074] The real-time detection information in this embodiment takes into account the throttle opening, duration, driving speed of the user when driving on different terrains, and combines the images captured by the camera and infrared images, which can provide more comprehensive judgment information and is conducive to better determining the current road surface environment.

[0075] As a preferred technical solution, the intelligent host unit IHU determines the current road surface environment according to the real-time detection information and in combination with the preset off-road environment judgment logic; the preset off-road environment judgment logic includes rock climbing environment judgment logic, snow environment judgment logic, and muddy environment judgment logic.

[0076] In this embodiment, the rock climbing environment judgment logic is used to determine whether to enter the climbing working condition, the snow environment judgment logic is used to determine whether to enter the snow road surface, and the muddy environment judgment logic is used to determine whether to enter the wading road surface or the rutted road surface. In this embodiment, the rutted road surface and the wading road surface both correspond to the muddy environment. Therefore, the muddy environment judgment logic is further divided into wading road surface judgment logic and rutted road surface judgment logic. The above off-road environment judgment logic will be further described below.

[0077] I. Rock climbing environment judgment logic

[0078] 1. Determine to enter the climbing working condition:

[0079] Condition: Gradient > 20°, duration (i.e., the time staying on the slope) > 2 s, vehicle speed > calibrated value.

[0080] Logic: When the above three conditions are simultaneously met, it is determined that the vehicle enters the climbing condition.

[0081] In specific implementation, the calibrated values of the vehicle speeds of BEV vehicles (battery electric vehicles) and ICE vehicles (internal combustion engine vehicles) are different.

[0082] 2. Determine to exit the climbing condition:

[0083] Condition: Gradient < 20° and duration (i.e., the time staying on the slope) > 2 s, vehicle speed > 40 km / h.

[0084] Logic: When any one of the above conditions is met or simultaneously met, it is determined that the vehicle exits the climbing condition.

[0085] In this embodiment, the gradient is obtained by the intelligent host unit (IHU) receiving and internally calculating.

[0086] Determination result: When the off-road environment meets the climbing condition, the IHU determines that the current road surface environment is a rock climbing environment.

[0087] II. Snow environment judgment logic

[0088] 1. Determine to enter the snow road surface (the snow mode in this embodiment is defined for light snow conditions and is not applicable to deep snow conditions. Therefore, the snow road surface in this embodiment is currently set as a light snow low adhesion road surface, and the wading radar is required to identify the depth):

[0089] Condition: The status of the snow signal data is sent (i.e., there is a snow signal), and the wading radar signal (identifying the snow depth) ≤ fixed value (in this embodiment, this fixed value is taken as 20 cm, i.e., the identified snow depth ≤ 20 cm).

[0090] Logic: When the above two conditions are simultaneously met, it is determined that the vehicle enters the snow road surface.

[0091] The snow signal in this embodiment is collected and sent by the front view camera (FVC).

[0092] 2. Determine to exit the snow road surface:

[0093] Condition: There is no snow signal, and the wading radar signal > fixed value (in this embodiment, it is > 20 cm).

[0094] Logic: When any one of the above conditions is met or simultaneously met, it is determined that the vehicle exits the snow road surface.

[0095] Judgment result: When the off-road environment conforms to the snow environment, the IHU determines that the current road surface environment is a snow environment.

[0096] III. Judgment Logic for Wading Environment

[0097] 1. Determine entering the wading road surface:

[0098] Condition: The wading radar signal (i.e., the transmitted depth signal Distance) > 20 cm and there are no obstacles underwater identified by infrared.

[0099] Logic: The IHU determines that the vehicle is in the wading working condition.

[0100] 2. Determine exiting the wading road surface:

[0101] Condition: There is no rain signal, the wading radar signal < 20 cm, and there are large obstacles underwater (only for reminder, not for exiting).

[0102] Logic: When any one of the above conditions is met or all are met simultaneously, it is determined that the vehicle exits the wading road surface.

[0103] In this embodiment, the rain signal is identified by a rain sensor. The measurement applies the principle of infrared light reflection. The device emits infrared light with a fixed intensity. When it rains on the glass on a rainy day, the amount of infrared light reflection becomes smaller. The amount of rain is determined according to the received light intensity, and a signal corresponding to the amount of rain is emitted; no rain signal means that the amount of rain is small / it is not raining, and the rain sensor does not emit a rain signal.

[0104] Wading scenarios are mostly on unpaved road surfaces. To prevent sudden changes in road surface depth and cause exiting, the condition is set: there are large obstacles underwater (only for reminder, not for exiting).

[0105] IV. Judgment Logic for Rutted Road Conditions

[0106] 1. Determine entering the rutted road surface:

[0107] Condition: The throttle opening > the average throttle opening of the user's habit (throttle opening percentage) and the vehicle speed < 40 km / h, and the duration of maintaining the set throttle opening > 2 s.

[0108] Logic: The IHU determines that the vehicle is on the rutted road surface.

[0109] 2. Determine exiting the rutted road surface:

[0110] Condition: The vehicle speed > 60 km / h, the throttle opening < the average throttle opening of the user's habit (%) and the duration > 4 s.

[0111] Logic: When any one of the above conditions is met or all are met simultaneously, it is determined that the vehicle exits the rutted road surface.

[0112] The rut condition judgment logic of this embodiment is set according to actual driving experience. In the rut condition, the contact area of the tire increases, the friction is large, and there will be a larger throttle opening at the same speed.

[0113] Judgment result: When the off-road environment conforms to a wading road surface or a rut road surface, the IHU determines that the current road surface environment is a muddy environment.

[0114] The duration in the above conditions is timed by the IHU. The IHU continuously records the slope (identified by the gyroscope) and the throttle opening, and continuously judges the corresponding conditions.

[0115] In this embodiment, both the wading environment and the rut condition correspond to the muddy environment. Therefore, both use the power MAP of the muddy mode.

[0116] The specific implementation of this solution combines vision, which is reflected in: by analyzing the road image, automatically determining the current road condition (that is, determining the current road surface environment).

[0117] As a preferred technical solution, according to the judgment result of the current road surface environment, the intelligent host unit IHU controls the all-terrain intelligent control multi-mode system to automatically switch to the best driving mode, including:

[0118] The multi-modes controlled by the all-terrain intelligent control multi-mode system include a snow mode, a muddy mode, a rock mode, and a standard mode;

[0119] If the intelligent host unit IHU determines that the vehicle is only in the muddy environment, the driving mode is automatically switched to the muddy mode;

[0120] If the intelligent host unit IHU determines that the vehicle is only in the snow environment, the driving mode is automatically switched to the snow mode;

[0121] If the intelligent host unit IHU determines that the vehicle is only in the rock climbing environment, the driving mode is automatically switched to the rock mode;

[0122] If the intelligent host unit IHU determines that the vehicle is simultaneously in the snow environment and the muddy environment, the driving mode is automatically switched to the snow mode;

[0123] If the intelligent host unit IHU determines that the vehicle is simultaneously in the snow environment and the rock climbing environment, or the vehicle is simultaneously in the muddy environment and the rock climbing environment, or the vehicle is simultaneously in the snow environment, the muddy environment and the rock climbing environment, the driving mode is automatically switched to the rock mode;

[0124] If the intelligent host unit IHU determines that the vehicle is not in a snow environment, a muddy environment, or a rock climbing environment, it automatically switches the driving mode to the standard mode. The all-terrain intelligent control multi-mode system of this embodiment includes a standard mode. When no off-road road conditions and conditions are recognized (that is, the IHU determines that the vehicle is not in a snow environment, a muddy environment, or a rock climbing environment), it enters the standard mode. Generally speaking, after the user finishes crossing (off-roading) and no OFFROAD (off-road environment) is recognized, the vehicle will enter the standard mode.

[0125] In this embodiment, the IHU determines the most suitable driving mode (i.e., the best driving mode) according to the determination result of the current road surface environment, and sends a corresponding driving mode signal to the relevant control system to optimize the vehicle performance and driving experience.

[0126] As a preferred technical solution, the method further includes: presetting a driving model considering the user's driving habits in the all-terrain intelligent control multi-mode system; when automatically switching to the best driving mode, the all-terrain intelligent control multi-mode system sends a driving mode signal corresponding to the best driving mode according to the driving model for vehicle control.

[0127] In this embodiment, the driving model is pre-set according to different vehicle models (BEV vehicles or ICE vehicles). The driving model includes a series of pre-defined set values, and vehicle control can be better performed through these set values. For example, when off-roading in a muddy environment, users generally use a large throttle to pass. The driving model can be established in the following way: First, analyze the driving behaviors of a large number of off-road vehicle users through the vehicle basic controller VCU (Vehicle Control Unit), EMS (Engine Management System), TCU (Transmission Control Unit), ICM (Instrument Cluster Meter), ATCM (Advanced Transmission Control Module), as well as the environmental recognition front-view camera, ultrasonic sensor, wading radar, road condition recognition infrared camera, drone, brightness sensor, and algorithm (the combination of the user's different driving habits and the road conditions recognized by the environment), including but not limited to the details of driving behavior data. Then, based on these data, create a driving model for novice off-road users and off-road enthusiasts. Introducing the created driving model in the intelligent driving mode of this embodiment can send a driving mode signal corresponding to the best driving mode for vehicle control when automatically switching to the best driving mode, thereby ensuring that each operation response conforms to the user's expectations and preferences, such as Figure 2As shown in the figure. In this embodiment, ELSD (Differential) and AWD (Intelligent All-Wheel Drive) are hardware components that operate independently and are not defined by modes; the TCU (Transmission Control Unit), EMS (Engine Management System), and ESP (ESP Controller Assembly) are automatically invoked according to the currently recognized driving mode.

[0128] In some embodiments, the All-Terrain Intelligent Control Multi-Mode System calls the corresponding driving mode MAP according to the driving model. For example, after recognizing a snow environment, it corresponds to the power, steering force, drive form, braking, TCS, etc. of the snow mode, and sends the corresponding driving mode signal for vehicle control.

[0129] Generally speaking, this solution takes into account the user's driving habits in two aspects. One is to automatically set the vehicle to enter the corresponding driving mode (i.e., enter the optimal driving mode) according to different driving conditions (i.e., different current road surface environments). The other is that when the All-Terrain Intelligent Control Multi-Mode System enters the optimal driving mode, it will send the driving mode signal corresponding to the optimal driving mode according to the driving model for vehicle control.

[0130] The All-Terrain Intelligent Control Multi-Mode System of the above embodiment can, through advanced electronic control hardware and a variety of sensors, intelligently adjust and intervene in the vehicle's four-wheel drive system, throttle response and other hardware according to preset logic, user habits and algorithms, providing higher safety and a better driving experience for novice off-roaders. This mode enables the vehicle to recognize the environment and combines the general (common) driving habits of users, not only reducing the difficulty of off-road driving, but also enabling more drivers to easily enjoy the fun of off-roading.

[0131] As a preferred technical solution, the switching of the central control display screen interface and the mode reminder include: switching the central control display screen interface to the user interface of the All-Terrain Intelligent Control Multi-Mode System; controlling the driving mode display on the instrument panel to be the intelligent driving mode through the Instrument Control Module ICM; lighting the intelligent driving mode indicator through the Automatic Transmission Control Module ATCM.

[0132] In this embodiment, when the Intelligent Host Unit (IHU) receives a signal (i.e., a command to activate the intelligent driving mode), it enters the All-Terrain Intelligent Control Multi-Mode System. At the same time, the central control display screen interface immediately switches to the user interface (UI) of the All-Terrain Intelligent Control Multi-Mode System, and a cool and technological off-road interface is presented on the central control display screen, showing all the information and options related to the All-Terrain Intelligent Control Multi-Mode System. Meanwhile, the ICM displays that the driving mode is the intelligent driving mode (i.e., the All-Terrain Intelligent Control Multi-Mode System): after receiving the signal from the IHU, the Instrument Cluster Meter (ICM) updates the driving mode display on the dashboard, clearly indicating that the current driving mode is the intelligent driving mode (i.e., the All-Terrain Intelligent Control Multi-Mode System). Meanwhile, the ATCM also lights up the indicator light for the intelligent driving mode (i.e., the All-Terrain Intelligent Control Multi-Mode System): after receiving the signal from the IHU, the All Terrain Control Module (ATCM) lights up the indicator light for the intelligent driving mode (i.e., the All-Terrain Intelligent Control Multi-Mode System). In this embodiment, the indicator light switch signal comes from the ATCM. Specifically, during implementation, the intelligent driving mode indicator light is integrated with the intelligent driving mode button and placed in front of the center console armrest. When the function is entered, the lights, instrument panel, and large screen enter simultaneously, giving the user a sense of technology and mystery, and visually reminding the user (driver) that the All-Terrain Intelligent Control Multi-Mode System has been entered.

[0133] The following describes the closing conditions of the intelligent driving mode in this embodiment.

[0134] When the user clicks the intelligent driving mode button on the driving mode switch again, the Intelligent Host Unit (IHU) receives a signal to turn off the All-Terrain Intelligent Control Multi-Mode System, and the IHU performs the following operations: switches back to the default driving mode UI interface; the Instrument Cluster Meter (ICM) updates the driving mode display on the dashboard to restore the default driving mode; the All Terrain Control Module (ATCM) turns off the indicator light for the All-Terrain Intelligent Control Multi-Mode System; turns off the wading radar and restores the soft switch of the wading radar to an operable state.

[0135] If the EPS assist mode was set to "Comfort" before clicking the intelligent driving mode button, it is restored to the default assist mode, and the EPS soft switch is restored to an operable state, which not only improves user convenience but also enhances the road feel. If the EPS assist mode was not set to "Comfort" before clicking the intelligent driving mode button, the steering assist mode set at the previous level is returned.

[0136] The following describes the abnormal interruption of the intelligent driving mode in this embodiment.

[0137] When the power mode of the vehicle is switched to OFF, the IHU receives a power-off signal, and the IHU performs the following operations: automatically exits the All-Terrain Intelligent Control Multi-Mode System and saves the current settings and status for restoration upon the next startup; the Instrument Control Module (ICM) updates the driving mode display on the instrument panel to restore to the default driving mode; the Automatic Transmission Control Module (ATCM) turns off the All-Terrain Intelligent Control Multi-Mode System indicator light; turns off the wading radar and restores the soft switch of the wading radar to an operable state.

[0138] If the EPS assist mode was previously set to "Comfort", it is restored to the default assist mode, and the EPS soft switch is restored to an operable state.

[0139] In some embodiments, considering the problem of obstructed vision in off-road environments, the intelligent driving mode (All-Terrain Intelligent Control Multi-Mode System) also integrates augmented reality (AR) and high-definition camera technologies to provide the driver with a clear road view and obstacle warnings. It can not only display the road conditions ahead in real time on the screen but also adjust the way and timing of information display according to the user's habits, enabling the driver to obtain the most timely and accurate auxiliary information while maintaining their familiar driving rhythm. Specifically, when the vision is obstructed (such as at night, in thick fog, in the woods, on a large slope), the AR system can use infrared cameras, ultrasonic sensors, and drones to expand the driver's visual range and clearly present what was originally invisible in the form of a 3D model on the HUD (specifically, the vehicle collects non-visual road information, integrates the information through the in-vehicle computer, generates the corresponding model in real time, and finally displays it on the HUD), so that the driver can see the enhanced visual information without shifting their line of sight, improving driving safety. The above-mentioned HUD refers to the Head-Up Display, that is, the head-up display system. For further reference, the prior art can be referred to and will not be elaborated here. Specifically in implementation, the vehicle can be equipped with a drone separately according to actual needs. The equipped drone can be used to assist in identifying road conditions and expanding the driver's visual range.

[0140] In some embodiments, the intelligent driving mode (All-Terrain Intelligent Control Multi-Mode System) can also help the driver better understand the lighting conditions under the current environmental conditions through environmental recognition, and can automatically adjust the irradiation direction and brightness of the lights according to the driving state of the vehicle and the external environment (including automatically adjusting the brightness through environmental color changes, adjusting the headlight power, irradiation height, irradiation width, etc.) to improve visibility at night or under adverse weather conditions.

[0141] In summary, when the user activates this intelligent driving mode, through the environmental intelligent recognition and consideration of driving habits introduced above, and then conducts intelligent adjustment and intervention, it can better bring appropriate driving mode switching to novice off-road users. Ultrasonic sensors, drones, etc. can provide users with a good driving view, enhancing playability and sense of security.

[0142] Based on the same inventive concept, the present invention also provides a computer-readable storage medium storing one or more programs, which, when executed, can implement the control method of the intelligent driving mode as described above.

[0143] Based on the same inventive concept, as Figure 3 shown, the present invention also provides an electronic device, including a processor, a communication interface, the computer-readable storage medium as described above, and a communication bus; wherein, the processor, the communication interface, and the computer-readable storage medium communicate with each other through the communication bus; the processor is used to execute the program stored in the computer-readable storage medium.
