Description

Technical Field

[0001] This invention belongs to the field of vehicle technology, and particularly relates to a vehicle off-road assist control method, device, vehicle, and storage medium. Background Technology

[0002] An all-terrain driving system is a control system that enhances a vehicle's off-road capabilities. It improves vehicle stability and off-road performance by coordinating subsystems such as the engine, transmission, four-wheel drive system, and differential locks. All-terrain driving systems include terrain modes such as Standard, Sport, Eco, Snow, Mud, Sand, 4L, and Rock, allowing even inexperienced drivers to easily maneuver the vehicle in various road conditions.

[0003] As the barrier to entry for off-road driving decreases, more and more novices are joining the sport. However, off-road driving involves harsh environments and high risks, demanding a high level of driver experience and operational skills. It also requires strict control over various vehicle functions. Improper operation can lead to anything from vehicle malfunction and loss of power to accidents. The inventors of this application have discovered that current all-terrain control systems generally only display whether the terrain mode has been successfully switched via the instrument panel. During off-road driving, there are no other relevant warnings or data displays to prompt the driver. Inexperienced drivers are prone to causing vehicle malfunctions or various alarms that restrict vehicle movement due to incorrect driving, which is detrimental to safe driving by those lacking off-road experience and affects the driver's off-road experience and vehicle passability. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a vehicle off-road assist control method, device, vehicle, and storage medium to provide users with assist prompts when the vehicle is off-roading, enabling users to control the vehicle more accurately, avoid improper operation of the vehicle, and improve the off-road experience and vehicle passability.

[0005] A first aspect of the present invention provides a vehicle off-road assist control method, comprising:

[0006] Obtain the currently selected terrain mode of the vehicle's all-terrain driving system;

[0007] The vehicle's various parameter values ​​are displayed in the all-terrain driving control interface on the vehicle's display screen;

[0008] The system determines whether the values ​​of each parameter exceed the corresponding warning values ​​for each parameter under the current terrain mode. If they do, the system will warn the user. The warning values ​​for each parameter under the current terrain mode are preset by the user and are less than the preset danger alarm thresholds for each parameter.

[0009] In conjunction with the first aspect, in one possible implementation of the first aspect, the vehicle parameters include at least one of the following:

[0010] Engine coolant temperature, transmission temperature, transfer case temperature, and engine turbine pressure.

[0012] Detect the terrain at the vehicle's current location;

[0013] Determine if the terrain matches the currently selected terrain mode of the vehicle's all-terrain driving system. If they do not match, prompt the user to switch to the terrain mode corresponding to the terrain.

[0014] Additionally, it determines whether the activation duration of the all-terrain driving system has reached a preset time threshold. If the time threshold is reached, the vehicle's various parameter values ​​are displayed in the all-terrain driving control interface on the vehicle's display screen; otherwise, the vehicle's various parameter values ​​are not displayed in the all-terrain driving control interface on the vehicle's display screen.

[0015] Furthermore, the terrain at the vehicle's current location is detected, including:

[0016] Acquire vehicle location information, tire slip rate change rate, and vehicle yaw rate change rate;

[0017] Determine at least one alternative terrain based on location information;

[0018] Based on the tire slip rate change rate and the vehicle yaw rate change rate, select one alternative terrain from at least one alternative terrain as the terrain for the vehicle's current location.

[0019] In conjunction with the first aspect, in one possible implementation of the first aspect, after obtaining the terrain mode currently selected by the vehicle's all-terrain driving system, it further includes:

[0020] Determine if the vehicle is currently in manual transmission mode;

[0021] If the vehicle is in manual transmission mode, obtain the vehicle's current speed;

[0022] Based on the current vehicle speed and the preset speed range corresponding to each gear in the currently selected terrain mode of the vehicle's all-terrain driving system, the system provides gear shift prompts to the user.

[0023] In conjunction with the first aspect, one possible implementation of the first aspect, when the user pre-sets the prompt values ​​corresponding to various parameters under each terrain mode, also includes:

[0024] Obtain vehicle configuration data related to various parameters, and determine the optimal setting range of prompt values ​​for various vehicle parameters under different terrain modes based on the configuration data;

[0025] The all-terrain driving control interface pushes the optimal setting range of various parameters to the user, so that the user can set the prompt values ​​of various parameters according to the optimal setting range.

[0026] In conjunction with the first aspect, in one possible implementation of the first aspect, the vehicle off-road assist control method further includes:

[0027] Receives electronic fan threshold setting commands input by the user through the all-terrain driving control interface;

[0028] Adjust the vehicle's electric fan activation threshold according to the electric fan threshold setting command.

[0029] A second aspect of the present invention provides a vehicle off-road assist control device, comprising:

[0030] The acquisition module is used to acquire the terrain mode currently selected by the vehicle's all-terrain driving system;

[0031] The display module is used to display various parameter values ​​of the vehicle within the all-terrain driving control interface on the vehicle's display screen.

[0032] The prompt module is used to determine whether the values ​​of various parameters exceed the prompt values ​​corresponding to the parameters in the current terrain mode. If they exceed, a prompt will be given to the user. The prompt values ​​corresponding to the parameters in the current terrain mode are preset by the user, and the prompt values ​​corresponding to the parameters are less than the preset danger alarm thresholds corresponding to the parameters.

[0033] A third aspect of the present invention provides a vehicle including an electronic device. The electronic device includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the steps of the vehicle off-road assist control method as described in the first aspect or any possible implementation of the first aspect.

[0034] A fourth aspect of the present invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of a vehicle off-road assist control method as described in the first aspect or any possible implementation of the first aspect.

[0035] The beneficial effects of the embodiments of the present invention compared with the prior art are as follows:

[0036] This invention displays various vehicle parameter values ​​on the all-terrain driving control interface of the vehicle's display screen, facilitating precise control of key vehicle data and functions during off-road driving. This prevents vehicle malfunctions or alarms that could restrict vehicle movement due to incorrect driving. Furthermore, by pre-setting warning values ​​for each parameter, all of which are less than the corresponding preset danger alarm thresholds, the system alerts the user when vehicle parameter values ​​exceed the warning values ​​for the current terrain mode. This provides early warning before the vehicle loses power or malfunctions, helping to guide users to use the vehicle correctly and safely, improving the off-road experience and vehicle passability. Attached Figure Description

[0037] To more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0038] Figure 1 This is a schematic diagram illustrating the implementation process of the vehicle off-road assist control method provided in an embodiment of the present invention;

[0039] Figure 2 This is a schematic diagram of the structure of the vehicle off-road assist control device provided in an embodiment of the present invention;

[0040] Figure 3 This is a schematic diagram of the structure of the electronic device provided in an embodiment of the present invention. Detailed Implementation

[0041] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0042] To illustrate the technical solution described in this invention, specific embodiments are described below.

[0043] The all-terrain driving system collects data on the characteristics of different road conditions and then writes scientific driving methods into the vehicle's program, thus pre-setting various road condition modes. When encountering complex terrain, the driver can select the appropriate mode according to different road conditions, and the onboard program will automatically adjust the settings to maximize the vehicle's performance. The main strategy of the all-terrain driving system is stored in ESP (Electronic Stability Program), which is composed of ESP, TOD (Torque On Demand), EMS (Engine Management System), TCU (Transmission Control Unit), and EGD (EGerodisc Differentials) system. Together, they form the entire control system, which can handle various terrain modes such as standard, economy, sport, snow, mud, sand, 4L, and rock, while also ensuring the vehicle can get out of trouble on various road surfaces.

[0044] In existing technologies, all-terrain driving systems control various subsystems based on the terrain mode selected by the driver and road information. When the system determines that the terrain mode has been successfully switched, it only informs the driver through the instrument display system whether the terrain mode has been successfully switched. During off-roading, there are no other relevant warnings or data displays to prompt the driver. For people with less off-road experience, it is easy to misjudge the vehicle's off-road performance, resulting in blind acceleration and aggressive driving. This causes severe impacts on the vehicle's transmission system, and important systems such as the engine and four-wheel drive are also prone to failure due to relevant conditions, resulting in the vehicle losing power. This not only affects the vehicle's passability and safety during off-roading, but also leads to a decline in the vehicle's brand image.

[0045] Therefore, the present invention provides a vehicle off-road assist control method to solve the above problems.

[0046] Figure 1 This is a schematic diagram illustrating the implementation flow of the vehicle off-road assist control method provided in an embodiment of the present invention. See also... Figure 1 As shown, the method includes the following steps:

[0047] Step S101: Obtain the currently selected terrain mode of the vehicle's all-terrain driving system.

[0048] In this embodiment of the invention, terrain modes include, but are not limited to, Standard, Eco, Sport, Snow, Mud, Sand, and 4L modes. Standard mode is suitable for normal driving under ordinary conditions (highways, paved roads, asphalt roads, etc.) and is the most comfortable driving mode. Eco mode reduces vehicle fuel consumption. Sport mode is suitable for fast driving on good road conditions, such as urban elevated roads or intercity highways, providing the most sporty driving experience. Snow mode is mainly used for slippery surfaces such as ice and snow. Mud mode is suitable for muddy, deep ditches, loose, or uneven surfaces. Sand mode is suitable for dry sand with a certain yield strength, such as dry sand, beaches, dunes, and deserts. 4L mode is suitable for conditions requiring high torque and low-speed forward movement, such as getting out of trouble; in this mode, the vehicle's torque is amplified by 2.48 times.

[0049] Step S102: Display the various parameter values ​​of the vehicle in the all-terrain driving control interface on the vehicle display screen.

[0050] In this embodiment, the traditional all-terrain driving system only informs the driver whether the terrain mode has been successfully switched through the instrument display system. People with less off-road experience find it difficult to accurately control the various data of the vehicle, which can easily lead to improper operation, resulting in the vehicle losing power or even causing an accident.

[0051] This embodiment utilizes an all-terrain driving control interface (or off-road information status display interface) to facilitate real-time monitoring of important parameters by the driver. Specifically, the vehicle's main unit (HUT) identifies mode switching request signals from the all-terrain controller (ATS). Upon successful mode switching, the HUT displays the mode information on the vehicle's display screen. If no further mode switching request signal is received within a certain time, the ATS sends a request to the HUT to display vehicle parameter status. The HUT then displays various important vehicle parameter values ​​on the off-road information status display interface for monitoring.

[0052] These parameters include, but are not limited to, engine speed, tire pressure, engine coolant temperature, transmission temperature, transfer case temperature, and engine turbine pressure.

[0053] The display screen can be the vehicle's multimedia screen or instrument panel screen, etc.

[0054] Step S103: Determine whether the values ​​of each parameter exceed the corresponding prompt values ​​for each parameter in the current terrain mode. If they do, a prompt is issued to the user. The prompt values ​​for each parameter in the current terrain mode are preset by the user, and the prompt values ​​for each parameter are less than the preset danger alarm thresholds for each parameter.

[0055] In this embodiment, vehicles typically have preset danger warning thresholds for various parameters. When the values ​​of these parameters exceed the danger warning thresholds, the vehicle may malfunction. However, in this embodiment, to guide the driver to use the vehicle safely in off-road conditions, the driver can set the warning values ​​for various parameters themselves. These warning values ​​are lower than the danger warning thresholds. For example, if the danger warning threshold for engine coolant temperature is 120°C, the warning value for engine coolant temperature can be set to 110°C. This provides early warnings, guiding the driver to operate the vehicle correctly and preventing certain important parameters from exceeding the danger warning thresholds, which could lead to loss of power or malfunction of the vehicle.

[0056] As can be seen, this embodiment of the invention displays various vehicle parameter values ​​on the all-terrain driving control interface of the vehicle display screen, facilitating users' precise control of key vehicle data and functions during off-road driving, and avoiding vehicle malfunctions or various alarms that restrict vehicle movement due to incorrect driving. Furthermore, by pre-setting prompt values ​​for each parameter, all of which are less than the preset danger alarm thresholds for each parameter, a prompt is given to the user when the parameter value exceeds the prompt value corresponding to the parameter in the current terrain mode. This provides early warning before the vehicle loses power or malfunctions, helping to guide users to use the vehicle correctly and safely, improving the off-road experience and vehicle passability.

[0057] In one possible implementation, in step S102, the vehicle parameters include, but are not limited to, at least one of the following:

[0058] Engine coolant temperature, transmission temperature, transfer case temperature, and engine turbine pressure.

[0059] In this embodiment, due to the harsh off-road conditions, especially during desert terrain such as hill climbing, the engine coolant temperature can easily overheat, causing the vehicle to lose power and creating a driving hazard. Therefore, the engine coolant temperature can be displayed on the off-road information status display interface to help the driver understand the current operating status. Based on the thermostat arrangement, the driver can set the initial opening temperature of the thermostat main valve through the all-terrain driving control interface. When the engine coolant temperature reaches the set value, a warning message will be issued to remind the driver to drive cautiously and stop off-road activities to avoid loss of power and potential danger.

[0060] In one embodiment, the user can also input an electronic fan threshold setting command through the all-terrain driving control interface to adjust the vehicle's electronic fan activation threshold. The vehicle's electronic fan is controlled by a thermostat and is designed to prevent the engine coolant temperature from becoming too high. It consists of sensors, the electronic fan itself, and chips. When the engine coolant temperature generally exceeds 90 degrees Celsius, the electronic fan activates to lower the temperature. This embodiment lowers the vehicle's electronic fan activation threshold, causing the fan to start earlier to help dissipate engine heat and improve the vehicle's off-road performance.

[0061] Similarly, during off-road driving, when a vehicle is digging its way out of a ditch, wheel slippage can easily cause the transmission friction plates and transfer case friction plates to slip and wear. After a period of time, this can lead to an overheating alarm for the transmission or transfer case oil. Overheating of the transmission can cause the vehicle to lose power, and overheating of the transfer case can cause the four-wheel drive system to malfunction. Both of these will limit the vehicle's power. Therefore, displaying the temperature of the transmission and transfer case through the all-terrain driving control interface allows the driver to easily observe the temperature changes of the relevant systems. By setting warning values, the driver can be alerted when the relevant systems are about to overheat, thus avoiding driving risks caused by overheating of the vehicle's relevant systems.

[0062] The addition of an engine turbo pressure display allows drivers to observe the turbocharger engagement time and internal pressure changes, thereby determining the vehicle's power status and power output direction. This enables drivers to better understand vehicle operating parameters and improve safety and off-road capability.

[0063] It should be noted that the all-terrain driving control interface in this embodiment can not only display engine coolant temperature, transmission temperature, transfer case temperature and turbo pressure, but also parameters such as engine speed according to actual needs. If other related parameters need to be added for monitoring, they can be pushed and upgraded via OTA.

[0064] In one possible implementation, after obtaining the currently selected terrain mode of the vehicle's all-terrain driving system in step S101, the following may also be included:

[0065] Detect the terrain at the vehicle's current location;

[0066] Determine if the terrain matches the currently selected terrain mode of the vehicle's all-terrain driving system. If they do not match, prompt the user to switch to the terrain mode corresponding to the terrain.

[0067] In real life, drivers may forget to switch terrain modes when off-roading. For example, they may continue driving in the standard mode when entering sandy areas, or forget to switch back to the standard mode after returning from off-roading. This is not conducive to the vehicle performing at its best.

[0068] In one possible implementation, after obtaining the currently selected terrain mode of the vehicle's all-terrain driving system in step S101, the following may also be included:

[0069] The system determines whether the all-terrain driving system has been activated for a preset time threshold. If the threshold is reached, the system displays the vehicle's various parameter values ​​on the all-terrain driving control interface of the vehicle's display screen. Otherwise, the system does not display the vehicle's various parameter values ​​on the all-terrain driving control interface of the vehicle's display screen.

[0070] In this embodiment, the HUT identifies the mode switching request signal issued by the all-terrain controller. When the mode switching is successful, the HUT displays the mode information. If no all-terrain mode switching request is received within a certain time limit, the all-terrain controller sends a request to the HUT to display vehicle parameter status. This design, through a certain delay, achieves the technical effect of not displaying parameters in cases such as accidental activation of the all-terrain driving system, and only displaying parameters when there is a genuine off-road need.

[0071] Therefore, in this embodiment, the ATS can identify the current terrain of the vehicle. If the identification result shows that the current terrain does not match the terrain mode of the vehicle, it will send a prompt message to the HUT to remind the vehicle to switch modes. The prompt message can be a voice prompt or a prompt on the vehicle's display screen.

[0072] This strategy helps guide off-road novices to use their vehicles correctly and safely.

[0073] In one embodiment, the method for identifying the terrain at the current location of the vehicle is as follows:

[0074] Acquire vehicle location information, tire slip rate change rate, and vehicle yaw rate change rate;

[0075] Determine at least one alternative terrain based on location information;

[0076] Based on the tire slip rate change rate and the vehicle yaw rate change rate, select one alternative terrain from at least one alternative terrain as the terrain for the vehicle's current location.

[0077] In this embodiment, the ATS can more accurately analyze the terrain by identifying the rate of change of vehicle tire slippage and the rate of change of vehicle yaw angle, and by linking with GPS to confirm the current terrain of the vehicle. For example, if the current terrain is determined to be one of sand, mud, or snow based on the location information (the terrain varies in different seasons and weather conditions), the current terrain can be further determined by the rate of change of tire slippage and the rate of change of vehicle yaw angle.

[0078] In one embodiment, the method for identifying the terrain at the current location of the vehicle can also be:

[0079] The terrain image of the vehicle's current location is collected by a 360° image acquisition device installed on the vehicle, and the terrain of the vehicle's current location is determined by image analysis and classification methods.

[0080] As one possible implementation, after obtaining the currently selected terrain mode of the vehicle's all-terrain driving system in step S101, the following may also be included:

[0081] Determine if the vehicle is currently in manual transmission mode;

[0082] If the vehicle is in manual transmission mode, obtain the vehicle's current speed;

[0083] Based on the current vehicle speed and the preset speed range corresponding to each gear in the currently selected terrain mode of the vehicle's all-terrain driving system, the system provides gear shift prompts to the user.

[0084] In this embodiment, during off-road driving, it is necessary to switch to manual mode in certain situations to facilitate gear shifting based on the working conditions and vehicle power performance. The primary basis for gear shifting is vehicle speed. By matching different shift speed ranges to different terrain modes, and providing shift prompts within each mode according to the set shift speed range, the driver can better control the vehicle, maintain good power output, and improve the vehicle's power performance and passability.

[0085] As one possible implementation, when the user pre-sets the prompt values ​​corresponding to various parameters in each terrain mode, it may also include:

[0086] Obtain vehicle configuration data related to various parameters, and determine the optimal setting range of prompt values ​​for various vehicle parameters under different terrain modes based on the configuration data;

[0087] The all-terrain driving control interface pushes the optimal setting range of various parameters to the user, so that the user can set the prompt values ​​of various parameters according to the optimal setting range.

[0088] In this embodiment, the optimal setting range for various parameters differs for vehicles with different configurations. For example, the optimal setting range for engine coolant temperature and engine turbo pressure is related to the vehicle's engine model. This implementation can pre-store the optimal setting range for different configuration data. After obtaining the vehicle's configuration data, the corresponding optimal setting range can be determined through table lookup, making this solution applicable to different vehicles. The optimal setting range for various vehicle parameters generally also differs under different terrain modes. An optimal setting range push function is added for setting the optimal setting range for each important parameter, facilitating settings for inexperienced users and providing guidance for correct vehicle use. Users can also directly set the pushed optimal setting range for each parameter with one click, and can set the prompt value for each parameter individually or with a single click.

[0089] In conjunction with the above, this invention provides a vehicle off-road assist control method. Based on the influence of relevant parameters on the vehicle's off-road performance during off-road driving, the all-terrain controller interacts with the HUT to display parameter status. It uses sensors to acquire engine coolant temperature, transmission temperature, transfer case temperature, and engine turbo pressure, and sets prompt values ​​for each parameter to provide safety alerts. This allows the driver to better understand the vehicle's operating parameters and drive the vehicle accordingly. It solves the problem of the lack of relevant display and warning for important parameters during off-road driving, avoids vehicle power failures that may be caused by insufficient driving experience during off-road driving, increases the vehicle's safety and passability in complex terrain conditions, and reduces the vehicle's failure rate.

[0090] The advantages of the embodiments of the present invention can be summarized in the following aspects:

[0091] (1) Create an off-road information status display interface to facilitate real-time monitoring of important parameters by the driver.

[0092] (2) The ATS, in conjunction with the GPS, identifies the road conditions of the vehicle and provides prompts for switching driving modes to match the current road conditions, thus guiding the driver to use the vehicle correctly.

[0093] (3) Based on different all-terrain modes, different shift lines are matched to prompt the shifting time, so that the driver can better control the vehicle and keep the vehicle with good power output.

[0094] (4) By monitoring engine coolant temperature, transmission temperature, transfer case temperature and engine turbine pressure and setting warning values, the system can provide an early warning before the vehicle loses power, reminding the driver to pay attention to the current vehicle parameters and avoid causing vehicle malfunctions. This helps guide novice drivers to drive correctly and safely.

[0095] (5) By manually setting prompt values, important components such as engines and transmissions can be used under more reasonable working conditions, which helps to keep important vehicle parts in good working condition, extend the service life of key components, reduce the vehicle's maintenance rate, and improve the vehicle's product competitiveness.

[0096] (6) Added the optimal setting range of prompt value to guide customers to use the vehicle correctly.

[0097] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0101] The prompt module 23 is used to determine whether the values ​​of each parameter exceed the prompt values ​​corresponding to each parameter in the current terrain mode. If they exceed, the user will be prompted.
