[0058] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0059] like Figure 1 As shown in the figure, an embodiment of the present invention provides a control method for an intelligent driving mode, the method comprising the following steps:

[0060] S1. After receiving the command to adjust the driving mode to intelligent driving mode, the intelligent host unit (IHU) enters the all-terrain intelligent control multi-mode system, and simultaneously switches the central control display screen interface and provides mode reminders.

[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 association status between 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 based on real-time detection information;

[0063] S4. Based on the current road environment assessment, the Intelligent Host Unit (IHU) controls the All-Terrain Intelligent Control Multi-Mode System to automatically switch to the optimal driving mode and sends the corresponding driving mode signal to control the vehicle.

[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 referred to as the all-terrain mode), the switching of the central control display screen interface can facilitate the user to operate the all-terrain intelligent control multi-mode system, the mode prompting can clearly prompt the user that the vehicle has entered the intelligent driving mode, the IHU detects the state of the all-terrain intelligent control multi-mode system and adjusts it, which can facilitate the subsequent better operation of the all-terrain intelligent control multi-mode system to realize the intelligent driving mode. The above scheme adopts the all-terrain intelligent control multi-mode system, can perform intelligent adjustment and intervention, automatically switches the driving mode by identifying the environment of the vehicle (i.e., the IHU determines the current road environment according to real-time detection information) and combining the driving habits of the user (i.e., the IHU automatically switches to the best driving mode according to the determination result, and sends a driving mode signal corresponding to the best driving mode for vehicle control), which can provide better driving experience for the user and better meet the off-road driving needs of the user.

[0065] In specific implementation, the user starts the intelligent driving mode by one key through clicking the intelligent driving mode button. When the user clicks the button, the intelligent host unit IHU receives the command of adjusting 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 the state of the all-terrain intelligent control multi-mode system and adjusts it, which includes detecting the state of the wading radar (Depth Wading Detection, DWD) and adjusting it, and detecting the association state of the electric power steering system EPS and the all-terrain intelligent control multi-mode system and adjusting it, which will be described below.

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

[0068] In the embodiment, the IHU determines the wading radar state of the all-terrain intelligent control multi-mode system and memorizes (the memory refers to storing the current state of the wading radar, and the memory depth changes in real time, which can be used to determine the boundary conditions of various off-road environment judgment logics set in the subsequent text) that the wading radar should be turned on and the corresponding soft switch should be in an inoperable state to avoid the user manually turning it off and lacking road condition judgment conditions. Specifically, the IHU detects the state of the wading radar and memorizes it, identifies the wading depth and snow depth through the wading radar, and the wading radar can identify a depth of 0cm-100cm. 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 user misoperation. If the user clicks to turn it off, a prompt of “current mode cannot be turned off” is given. In the embodiment, the function of the wading radar is mainly to detect the road surface depth condition, which is used to determine whether the vehicle is in wading / snow. For the present solution, the IHU enters the all-terrain intelligent control multi-mode system, and the wading radar must be in an open state because the wading signal is needed for the judgment condition of subsequent mode switching, so 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 the association state of the electric power steering system EPS and the all-terrain intelligent control multi-mode system and adjusts it, including: the intelligent host unit IHU detects the association state of the electric power steering system EPS and the all-terrain intelligent control multi-mode system; if associated, the EPS-OFF instruction is issued and the EPS assist mode is set to comfortable, and the EPS soft switch is set to an inoperable state; if not associated, the current EPS assist mode is maintained.

[0070] In the embodiment, the IHU detects the association state of the electric power steering system (EPS) and the all-terrain intelligent control multi-mode system. If the EPS is associated with the all-terrain intelligent control multi-mode system, the EPS-OFF instruction is issued through the large screen (i.e., the central control display screen), the EPS assist mode is set to “comfortable”, and the EPS soft switch is set to an inoperable state, which can avoid the user mistakenly re-associating the EPS with the all-terrain intelligent control multi-mode system, because when driving on multi-terrain roads, the steering force changes greatly after the driving mode (i.e., the all-terrain intelligent control multi-mode system) is associated with the steering (EPS), which will bring about a poor driving experience. In the embodiment, after exiting the all-terrain intelligent control multi-mode, the EPS is associated with each driving mode (for example, the economy mode corresponds to the light EPS, and the sports mode corresponds to the sports EPS). If the EPS is not associated with the all-terrain intelligent control multi-mode system, the current assist mode is maintained unchanged.

[0071] In specific implementation, the user can set whether the EPS is associated with the all-terrain intelligent control multi-mode system through a large screen. The purpose of the present scheme is to have no large steering force change 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 water crossing radar signals, slope, snow field signals, infrared identification signals and rainy day signals; and the vehicle data includes vehicle speed and throttle opening degree.

[0073] In the present embodiment, the IHU determines the current road surface environment according to the water crossing radar signals, snow field signals, throttle opening degree, vehicle speed and duration, etc. Specifically, the IHU comprehensively analyzes the water crossing radar signals, snow field signals (the images are collected by the front-view camera, the snow field is identified by the camera self-learning, and the snow field signal is sent out after the intelligent algorithm processing identifies the snow field in accordance with the snow road surface characteristics), throttle opening degree (the throttle opening degree is derived from the engine control unit and sent out by the throttle pedal, and the throttle opening degree signal processed by the VCU is sent to the EMS), vehicle speed, and the duration (the throttle opening degree and duration signals are detected by the throttle pedal position sensor and processed by the electronic control unit of the vehicle) of the vehicle under different road conditions, etc. (i.e. real-time detection information) to determine the current road surface environment in real time, as shown in the following table. Figure 2

[0074] The real-time detection information of the present embodiment considers the throttle opening degree, duration, driving speed of the user in different terrains, and combines the images captured by the camera and the infrared images, which can provide more comprehensive judgment information and is beneficial to better determine 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 field environment judgment logic and muddy environment judgment logic.

[0076] In the present embodiment, the rock climbing environment judgment logic is used to determine whether to enter the climbing working condition, the snow field environment judgment logic is used to determine whether to enter the snow field road surface, and the muddy environment judgment logic is used to determine whether to enter the water crossing road surface or the ruts road surface. The ruts road surface and the water crossing road surface of the present embodiment both correspond to the muddy environment, so the muddy environment judgment logic is further subdivided into water crossing road surface judgment logic and ruts road surface judgment logic. The off-road environment judgment logic will be further described below.

[0077] I. Rock climbing environment judgment logic

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

[0079] Condition: Slope > 20°, Duration (i.e. the time of staying on the slope) > 2s, Vehicle speed > Calibration value.

[0080] Logic: When the above three conditions are met at the same time, it is determined that the vehicle enters the climbing slope working condition.

[0081] In specific implementation, the calibration value of the vehicle speed of the BEV vehicle (battery electric vehicle) and the ICE vehicle (internal combustion engine vehicle) is different.

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

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

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

[0085] In this embodiment, the slope is received by the intelligent host unit (IHU) and calculated internally.

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

[0087] II. Snow environment judgment logic

[0088] 1. Determine to enter the snow road surface (the snow mode of this embodiment is defined for shallow snow working condition, and is not applicable to deep snow condition, so the snow road surface of this embodiment is currently set to shallow snow low adhesion road surface, and the water wading radar is required to identify the depth):

[0089] Condition: Snow signal data state is issued (i.e. there is a snow signal), Water wading radar signal (identify snow depth) ≤ fixed value (the fixed value of this embodiment is taken as 20cm, i.e. the identified snow depth ≤ 20cm).

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

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

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

[0093] Condition: No snow signal, Water wading radar signal > fixed value (this embodiment is > 20cm).

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

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

[0096] III. Wading Environment Judgment Logic

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

[0098] Conditions: wading radar signal (i.e., sending depth signal Distance) > 20 cm and infrared recognition of no underwater obstacles.

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

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

[0101] Conditions: rain signal has no signal, wading radar signal < 20 cm, and there are large underwater obstacles (only for warning, not for exiting).

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

[0103] In this embodiment, the rain signal is identified by a rain sensor, which measures the application of infrared light reflection principle. The device emits a fixed intensity infrared light. When it rains on the windshield, the amount of infrared light reflection decreases. The amount of rain is determined according to the received light intensity, and a signal corresponding to the size of the rain is sent. No rain signal indicates that the amount of rain is small / no rain, and the rain sensor does not send a rain signal.

[0104] Wading scenarios are mostly non-paved roads, and sudden changes in road surface depth are prevented, so the condition is set: there are large underwater obstacles (only for warning, not for exiting).

[0105] IV. Rutting Condition Judgment Logic

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

[0107] Conditions: accelerator opening > user habit average opening (accelerator opening size %) and vehicle speed < 40 km / h, and set accelerator opening duration > 2 s.

[0108] Logic: the IHU determines that the vehicle is in a rutting road surface.

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

[0110] Conditions: vehicle speed > 60 km / h, accelerator opening < user habit average opening (%) and duration > 4 s.

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

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

[0113] The determination result is that the IHU determines that the current road surface environment is a muddy environment when the off-road environment meets the water-involved road surface or the rut road surface.

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

[0115] In the embodiment, the water-involved environment and the rut working condition both correspond to the muddy environment, so the two use the power MAP of the muddy mode.

[0116] The specific implementation of the scheme combines vision, which is embodied in that the current road working condition (i.e., the determination of the current road surface environment) is automatically determined through analysis of the road image.

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

[0118] The multi-mode controlled by the full-terrain intelligent control multi-mode system includes 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 a 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 a snowy environment, the driving mode is automatically switched to the snowy mode;

[0121] If the intelligent host unit IHU determines that the vehicle is only in a 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 in a snowy environment and a muddy environment at the same time, the driving mode is automatically switched to the snowy mode;

[0123] If the intelligent host unit IHU determines that the vehicle is in a snowy environment and a rock climbing environment at the same time, or the vehicle is in a muddy environment and a rock climbing environment at the same time, or the vehicle is in a snowy environment, a muddy environment, and a rock climbing environment at the same time, 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, the driving mode is automatically switched to the standard mode. The standard mode is included in the all-terrain intelligent control multi-mode system of the embodiment, and the standard mode is entered when no off-road conditions are identified (i.e., the intelligent host unit IHU determines that the vehicle is not in a snow environment, a muddy environment, or a rock climbing environment). Generally, after the user finishes crossing (off-roading), the standard mode is entered when no off-road environment is identified.

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

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

[0127] In the embodiment, the driving model is pre-set according to different vehicle types (BEV vehicles or ICE vehicles), and the driving model includes a series of predefined set values, through which the vehicle can be better controlled, for example, the user generally uses a large throttle to pass through in the mud (muddy environment). The driving model can be established in the following way: first, analyze a large number of off-road vehicle user driving behaviors through the vehicle basic controller VCU (Vehicle Control Unit, vehicle controller), EMS (Engine Management System, engine management system), TCU (Transmission Control Unit, transmission controller), ICM (Instrument Cluster Meter, instrument control module), ATCM (Advanced Transmission Control Module, automatic transmission control module), and environmental recognition front-view camera, ultrasonic sensor, wading radar, road condition recognition infrared camera, unmanned aerial vehicle, brightness sensor, and algorithm (combination of user driving habits and environmental recognition road conditions), including but not limited to driving behavior data details, and then create a driving model for off-road beginners and off-road enthusiasts based on these data. The embodiment introduces the created driving model in the intelligent driving mode, which can send a driving mode signal corresponding to the optimal driving mode for vehicle control when automatically switching to the optimal driving mode, thereby ensuring that every operation response meets the user's expectations and preferences, such as Figure 2The ELSD (differential) and AWD (intelligent four-wheel drive) are hardware in this embodiment and operate independently without mode definition; the TCU (transmission controller), EMS (engine management system), and ESP (ESP controller assembly) are automatically invoked according to the currently identified driving mode.

[0128] In some embodiments, the all-terrain intelligent control multi-mode system invokes the corresponding driving mode MAP according to the driving model, such as identifying a snow environment and then corresponding to the power, steering force, driving form, braking, TCS, etc. of the snow mode, and sends the corresponding driving mode signal for vehicle control.

[0129] In general, this scheme considers that the user's driving habits are reflected 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 conditions), and the other is that the all-terrain intelligent control multi-mode system will send the driving mode signal corresponding to the optimal driving mode for vehicle control when it enters the optimal driving mode according to the driving model.

[0130] The all-terrain intelligent control multi-mode system of the above embodiments can intelligently adjust and intervene in the vehicle four-wheel drive system, throttle response, etc. through advanced electronic control hardware and various sensors, according to the pre-set logic, user habits and algorithms, to provide higher safety and better driving experience for off-road beginners. This mode identifies the environment of the vehicle and combines the user's general (universal) driving habits, not only reducing the difficulty of off-road driving, but also allowing more drivers to easily enjoy the fun of off-road driving.

[0131] As a preferred technical solution, the switching of the central control display screen interface and the mode prompting includes: switching the central control display screen interface to the all-terrain intelligent control multi-mode system user interface; controlling the driving mode display on the instrument panel to be the intelligent driving mode through the instrument control module ICM; and lighting the intelligent driving mode indicator light 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 start the intelligent driving mode), the all-terrain intelligent control multi-mode system is entered, and the central control display screen interface is immediately switched to the all-terrain intelligent control multi-mode system user interface (UI). The central control display screen presents a cool and technologically advanced off-road interface, displaying all information and options related to the all-terrain intelligent control multi-mode system. At the same time, the ICM displays the driving mode as the intelligent driving mode (i.e., the all-terrain intelligent control multi-mode system). After the intelligent host unit (IHU) receives a signal, the instrument cluster meter (ICM) updates the driving mode display on the instrument panel, clearly indicating that the current driving mode is the intelligent driving mode (i.e., the all-terrain intelligent control multi-mode system). At the same time, the all-terrain control module (ATCM) also illuminates the intelligent driving mode (i.e., the all-terrain intelligent control multi-mode system) indicator light. In this embodiment, the intelligent driving mode indicator light and the intelligent driving mode button are integrated and placed in front of the central armrest table. When the function is entered, the lights, instruments, and large screens are synchronized to enter, giving users a sense of technology and mystery, and reminding users (drivers) in a visual way that they have entered the all-terrain intelligent control multi-mode system.

[0133] The closing conditions of the intelligent driving mode of the present embodiment are described below.

[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 close the all-terrain intelligent control multi-mode system, and the IHU performs the following operations: switching back to the default driving mode UI interface; the instrument cluster meter (ICM) updates the driving mode display on the instrument panel, restoring it to the default driving mode; the all-terrain control module (ATCM) extinguishes the all-terrain intelligent control multi-mode system indicator light; and the wading radar is turned off, and the wading radar soft switch is restored to an operable state.

[0135] If the EPS assist mode was set to "comfort" before the intelligent driving mode button was clicked, it is restored to the default assist mode, and the EPS soft switch is restored to an operable state, not only improving user convenience, but also enhancing road feel. If the EPS assist mode was not set to "comfort" before the intelligent driving mode button was clicked, it returns to the steering assist mode set at the previous level.

[0136] The abnormal interruption of the intelligent driving mode of the present embodiment is described below.

[0137] When the power mode of the vehicle is switched to OFF, the IHU receives a signal of power-off, the IHU performs the following operations: automatically exiting the all-terrain intelligent control multi-mode system, and saving the current settings and state for recovery next time; the instrument control module (ICM) updates the driving mode display on the instrument panel, and restores to the default driving mode; the automatic transmission control module (ATCM) extinguishes the all-terrain intelligent control multi-mode system indicator light; the wading radar is turned off, and the wading radar soft switch is restored to an operable state.

[0138] If the previous EPS assist mode is 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 view in off-road environment, the intelligent driving mode (all-terrain intelligent control multi-mode system) also integrates augmented reality (AR) and high-definition camera technology to provide the driver with a clear road view and obstacle warning. It not only displays the road conditions in front of the vehicle in real time on the screen, but also adjusts the way and timing of information display according to the user's habits, so that the driver can maintain his familiar driving rhythm while obtaining the most timely and accurate assistance information. Specifically, when the view is obstructed (such as at night, in heavy fog, in the woods, or on a steep slope), the AR system can use infrared cameras, ultrasonic sensors, and unmanned aerial vehicles to expand the driver's visual range, and clearly display the 3D model of the invisible objects on the HUD (specifically, the vehicle collects non-visual information on the road, the information is integrated by the vehicle infotainment system, a corresponding model is generated in real time, and finally displayed on the HUD). In this way, the driver can see the enhanced visual information without shifting his gaze, improving driving safety. The above-mentioned HUD represents Head-Up Display, which can be further referred to the prior art, and will not be described here. In specific implementation, the vehicle can be equipped with a single unmanned aerial vehicle according to actual needs. The unmanned aerial vehicle 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 automatically adjust the illumination 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 power, height, and width of the headlights, etc.), to improve the visibility in night or bad weather conditions.

[0141] In summary, when the user activates this intelligent driving mode, through the above-mentioned environmental intelligent recognition and considering the driving habits, intelligent adjustment and intervention are further carried out, which can better bring suitable driving mode switching to off-road novice users, and ultrasonic sensors, unmanned aerial vehicles and the like can bring good driving vision to the user and improve playability and safety.
