Description

Technical Field

[0001] The present application relates to the field of vehicles, and more specifically, to a control method, a device and a vehicle. Background Art

[0002] As smart vehicles are widely used in daily life, air suspensions are installed in smart vehicles to improve user comfort. The air suspension can be composed of air springs, smart cockpit domain controller (CDC) shock absorbers, air supply units, control units, acceleration sensors, height sensors, etc. When driving a vehicle, users can control the air suspension to change the height of the vehicle body to adjust the air resistance. Especially when the vehicle is driving on potholes, bumps, and other roads, the above operations can improve the smoothness of the vehicle's driving and improve the user's driving comfort.

[0003] However, currently users need to manually click on the central control screen of the smart vehicle to adjust the gear of the air suspension, which makes the user's driving safety and comfort poor. Summary of the invention

[0004] The present application provides a control method, device and vehicle, which can improve the safety of the vehicle when driving on bumpy roads and the driving comfort of the user, and enhance the user's human-computer interaction experience.

[0005] In a first aspect, a control method is provided, the method comprising: obtaining the degree of bumpiness of a first road section; when the degree of bumpiness of the first road section meets a preset condition, controlling a prompt device to prompt a user to adjust the height of an air suspension; and controlling the height of the air suspension according to a first input of the user.

[0006] Optionally, the user's first input may be voice input, key input or touch screen input.

[0007] Optionally, the bumpiness of the first road section may refer to the unevenness of the road surface.

[0008] Optionally, the vehicle may control to raise the height of the air suspension or may control to lower the height of the air suspension according to the first input of the user.

[0009] In the embodiment of the present application, when the vehicle is traveling on the first road section, if the bumpiness of the first road section meets the preset conditions, the user can be prompted to adjust the height of the air suspension, and the height of the air suspension can be controlled to be raised or lowered according to the user's response. In this way, the safety of the vehicle traveling on bumpy roads and the driving comfort of the user can be improved, and the user's human-computer interaction experience can be enhanced.

[0010] In combination with the first aspect, in certain implementations of the first aspect, when the bumpiness of the first road section meets a preset condition, the prompt device is controlled to prompt the user to adjust the height of the air suspension, including: when the bumpiness of the first road section is greater than or equal to a first preset threshold, the prompt device is controlled to prompt the user to increase the height of the air suspension; or when the bumpiness of the first road section is less than or equal to a second preset threshold, the prompt device is controlled to prompt the user to lower the height of the air suspension; wherein the first preset threshold is greater than the second preset threshold.

[0011] Alternatively, the bumpiness of the first road section meeting the preset condition may be that the roughness of the first road section exceeds a preset roughness range.

[0012] In an embodiment of the present application, when the bumpiness of the first road section is greater than a first preset threshold, the user can be prompted to increase the height of the air suspension. When the bumpiness of the first road section is less than a second preset threshold, the user can be prompted to lower the height of the air suspension. In this way, the user can better adapt to different driving environments, thereby improving the driving experience.

[0013] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: controlling the height of the air suspension according to the first input of the user, including: adjusting the height of the air suspension to a first height when the first input indicates adjusting the height of the air suspension; the method further includes: saving a first corresponding relationship between the first road section and the first height.

[0014] In an embodiment of the present application, the vehicle can control the prompt device to save the first correspondence between the first height of the air suspension and the first road section. In this way, when the vehicle travels on the first road section again, the vehicle can directly control the height of the air suspension to the first height based on the above correspondence without having to interact with the user again.

[0015] In combination with the first aspect, in certain implementations of the first aspect, before it is detected that the vehicle passes through the first road section again, the height of the air suspension is adjusted to the first height according to the first corresponding relationship.

[0016] Optionally, the vehicle may first prompt the user whether to adjust the height of the air suspension to the first height, and after obtaining confirmation from the user, the vehicle may adjust the height of the air suspension to the first height.

[0017] In an embodiment of the present application, before detecting that the vehicle passes through the first road section again, the vehicle can directly control the height of the air suspension based on the first corresponding relationship without interacting with the user again. In this way, it can improve the safety of the vehicle's driving on bumpy roads while providing the user with a more comfortable driving experience.

[0018] In combination with the first aspect, in some implementations of the first aspect, the method further includes: determining the adjusted height of the air suspension according to a degree of bumpiness of the first road section.

[0019] In combination with the first aspect, in certain implementations of the first aspect, determining the adjusted height of the air suspension based on the bumpiness of the first road section includes: when the first input is used to indicate adjustment of the height of the air suspension, controlling the height of the air suspension based on the bumpiness of the first road section and a second correspondence, the second correspondence including a correspondence between the bumpiness of the road section and the height of the air suspension.

[0020] In the embodiment of the present application, after the first input is used to indicate that the user agrees to adjust the height of the air suspension, the vehicle can control the height of the air suspension according to the second correspondence between the bumpiness of the first road section and the height of the air suspension. In this way, when the bumpiness of the first road section is large, the height of the air suspension is also large, which is conducive to further improving the safety of the vehicle driving on bumpy roads and the driving comfort of the user.

[0021] In combination with the first aspect, in certain implementations of the first aspect, controlling the height of the air suspension according to the first input of the user includes: when the bumpiness of the first road section is greater than or equal to the first preset threshold and the first input indicates not to adjust the height of the air suspension, controlling the height of the air suspension to remain unchanged, and saving the correspondence between the user's identification information and a third preset threshold, the third preset threshold being greater than the first preset threshold.

[0022] In the embodiment of the present application, after the first input is used to indicate that the user does not agree to adjust the height of the air suspension, the vehicle may not adjust the height of the air suspension, and dynamically update the correspondence between the user and the third preset threshold. In this way, since different users have different tolerances for road bumps, when the user's tolerance is high, the preset threshold needs to be set higher, so that while improving the vehicle's intelligence, it can also further improve the user's driving experience.

[0023] In combination with the first aspect, in certain implementations of the first aspect, the method also includes: obtaining the degree of bumpiness of a second road section on which the vehicle is located when the user is in the vehicle; when the degree of bumpiness of the second road section is greater than or equal to the third preset threshold, controlling the prompt device to prompt the user to adjust the height of the air suspension.

[0024] In an embodiment of the present application, after the vehicle saves the correspondence between the user and the third preset threshold, when the vehicle detects that the bumpiness of the second road section is greater than the third preset threshold, the vehicle control prompt device prompts the user to adjust the height of the air suspension. In this way, the intelligence level of the vehicle can be improved, which is conducive to providing users with a personalized driving experience.

[0027] Optionally, the cloud device may include: a server, a network device, or a base station.

[0028] In an embodiment of the present application, the vehicle can obtain the degree of bumpiness of the first road section and send the degree of bumpiness of the first road section to a cloud device, which determines whether the degree of bumpiness of the first road section meets a preset condition. If the preset condition is met, the cloud device can send a first message to the vehicle, and the vehicle can prompt the user to adjust the height of the air suspension based on the first message. In this way, the vehicle does not need to determine whether the degree of bumpiness of the first road section meets the preset condition, thereby saving the vehicle's computing resources.

[0059] The vehicle 100 may include a variety of subsystems, such as a perception system 120, a computing platform 130, and a prompting device 140. Optionally, the vehicle 100 may include more or fewer subsystems, and each subsystem may include one or more components. In addition, each subsystem and component of the vehicle 100 may be interconnected by wire or wirelessly.

The processor is a circuit with signal processing capability. In one implementation, the processor may be a circuit with instruction reading and execution capability, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which may be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor may implement certain functions through the logical relationship of a hardware circuit, and the logical relationship of the hardware circuit may be fixed or reconfigurable, such as a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA.

[0066] The following takes vehicle 100 as an intelligent vehicle as an example to illustrate the technical problems to be solved by the present application and the technical solutions adopted.

[0067] As smart vehicles are widely used in daily life, in order to improve the comfort of users, air suspensions are installed in smart vehicles. Among them, air suspensions can be composed of air springs, CDC shock absorbers, air supply units, control units, acceleration sensors, height sensors, etc. When driving a vehicle, users can change the height of the vehicle body to adjust the air resistance by controlling the air suspension. Especially when the vehicle is driving on potholes, bumps and other roads, the above operations can improve the smoothness of the vehicle's driving and improve the user's driving comfort.

[0068] However, currently users need to manually click on the central control screen of the smart vehicle to adjust the gear of the air suspension, which makes the user's driving safety and comfort poor.

[0069] The embodiments of the present application provide a control method, a device, and a vehicle, which can improve the safety of the vehicle when driving on bumpy roads and the driving comfort of the user, and enhance the user's human-computer interaction experience.

[0070] Figure 2 2 is a schematic flow chart of a control method provided by an embodiment of the present application. The execution subject of method 200 may be a vehicle or a controller. When the execution subject of method 200 is vehicle 100, it may be executed by computing platform 130 in vehicle 100, or may be executed by system-on-chip (SoC) in computing platform 130, or may be executed by a processor in computing platform 130. The method 200 is introduced below with a vehicle as the execution subject. Method 200 may include steps S201 to S202.

[0071] S201, obtaining the bumpiness of the first road section.

[0072] Optionally, the bumpiness of the first road section may refer to the roughness of the road surface, and the vehicle may measure the roughness of the first road section based on the acceleration and the height of the air suspension.

[0073] In one embodiment, the vehicle may first obtain the current acceleration of the vehicle and the first height of the air suspension, and determine the road surface grade of the first road section based on the first height and the acceleration of the vehicle, and then determine the degree of bumpiness of the first road section based on the road surface grade of the first road section.

[0074] Optionally, the higher the grade of the road surface, the greater the bumpiness of the vehicle may be.

[0075] For example, the bumpiness of the vehicle may be determined by Table 1.

[0076] Table 1

[0077] Road surface grade Bumping degree First level ±1mm Second level ±3mm Third Level ±7mm

[0078] Optionally, the road surface grades in Table 1 may also be grades specified in the national standard GB T7031, for example, the first grade may be grade A, the second grade may be grade B, the third grade may be grade C, and so on.

[0079] In one embodiment, the vehicle may obtain the degree of bumpiness of the first road section based on navigation information, that is, the degree of bumpiness of the first road section may be directly marked in the navigation information.

[0080] In one embodiment, the terminal device may acquire the degree of bumpiness of the first road section, and inform the vehicle of the degree of bumpiness of the first road section through the second information.

[0081] Optionally, the terminal device may include: a mobile phone, a tablet computer, or a laptop computer.

[0082] S202: Control the height of the air suspension according to the degree of bumpiness of the first road section.

[0083] In one embodiment, the vehicle may directly control the height of the air suspension according to the degree of bumpiness of the first road section without interacting with the user.

[0084] In one embodiment, step S202 includes: when the bumpiness of the first road section meets a preset condition, the vehicle control prompting device prompts the user to adjust the height of the air suspension, and controls the height of the air suspension according to the user's first input.

[0085] In the embodiment of the present application, when the vehicle is traveling on the first road section, if the bumpiness of the first road section meets the preset conditions, the user can be prompted to adjust the height of the air suspension, and the height of the air suspension can be controlled to be raised or lowered according to the user's response. In this way, the safety of the vehicle traveling on bumpy roads and the driving comfort of the user can be improved, and the user's human-computer interaction experience can be enhanced.

[0086] Optionally, the prompt device may include at least one of the following: a voice prompt device, an ambient light or a display screen.

[0087] There are many ways to implement the bumpiness of the first road section satisfying the preset condition.

[0088] In one embodiment, when the bumpiness of the first road section is greater than or equal to a first preset threshold, the vehicle can control the prompt device to prompt the user to increase the height of the air suspension. When the bumpiness of the first road section is less than or equal to a second preset threshold, the vehicle can control the prompt device to prompt the user to lower the height of the air suspension.

[0089] For example, when the bumpiness of the first road section is represented by road surface roughness, the first preset threshold is set to 10 mm, and the second preset threshold is set to 4 mm, when the vehicle actually detects that the road surface roughness of the first road section is greater than or equal to 10 mm, the user may be prompted to increase the height of the air suspension by 20 mm. When the vehicle actually detects that the road surface roughness of the first road section is less than or equal to 4 mm, the user may be prompted to decrease the height of the air suspension by 20 mm.

[0090] In one embodiment, the bumpiness of the first road section meeting a preset condition may be that the roughness of the first road section exceeds a preset roughness range.

[0091] For example, when the bumpiness of the first road section is represented by road surface roughness, and the preset roughness interval is [-2mm, 8mm], when the road surface roughness of the first road section actually detected by the vehicle is not within the above interval, the user can be prompted to increase the height of the air suspension by 20mm. When the road surface roughness of the first road section actually detected by the vehicle is within the above interval, the user can be prompted to lower the height of the air suspension by 20mm. Among them, a positive number of road surface roughness can be understood as a convexity on the road surface, and a negative number of road surface roughness can be understood as a concave situation on the road surface.

[0092] There are many ways to implement the vehicle controlling the height of the air suspension according to the first input of the user.

[0093] Optionally, the user's first input may be voice input, key input or touch screen input.

[0094] For example, when the vehicle prompts the user to adjust the height of the air suspension through the voice prompt device, the vehicle detects that the user's voice input is "adjust the height of the air suspension". At this time, the vehicle can control the height of the air suspension based on the user's voice input.

[0095] For another example, when the vehicle prompts the user to adjust the height of the air suspension through the display screen, the vehicle detects the user's input of clicking the "adjust" control on the touch screen. At this time, the vehicle can control the height of the air suspension based on the user's touch screen input.

[0096] Optionally, the vehicle may control to raise the height of the air suspension or may control to lower the height of the air suspension according to the first input of the user.

[0097] In one embodiment, the vehicle may first determine the height of the air suspension after adjustment according to the degree of bumpiness of the first road section, and then adjust the height of the air suspension to the determined height according to the first input of the user.

[0098] For example, when the vehicle determines that the height of the air suspension after adjustment is the first height based on the bumpiness of the first road section, the vehicle can adjust the height of the air suspension to the first height when the first input indicates to adjust the height of the air suspension.

[0099] In one embodiment, the vehicle can save a first correspondence between a first height and a first road section. Before detecting that the vehicle passes through the first road section again, the vehicle can directly adjust the height of the air suspension to the first height without interacting with the user again. In this way, the vehicle can provide users with a more comfortable driving experience while improving the safety of driving on bumpy roads.

[0100] In one embodiment, when the user's first input is used to instruct to adjust the height of the air suspension, the vehicle can control the height of the air suspension according to the second correspondence between the bumpiness of the first road section and the height of the air suspension. In this way, when the bumpiness of the first road section is greater, the height of the air suspension is also greater, which is conducive to further improving the safety of the vehicle driving on bumpy roads and the driving comfort of the user.

[0101] Optionally, the second corresponding relationship may be as shown in Table 2.

[0102] Table 2

[0103] Bumping degree Air suspension height ±1mm +15mm ±3mm +30mm ±7mm +50mm

[0104] For example, when the user's first input indicates adjusting the height of the air suspension, and the vehicle detects that the bumpiness of the first road section meets the condition of ±3 mm, the vehicle may increase the height of the air suspension by 30 mm.

[0105] For another example, when the user's first input indicates not to adjust the height of the air suspension, even if the vehicle detects that the bumpiness of the first road section meets the conditions shown in Table 2, the vehicle may not adjust the height of the air suspension.

[0106] In one embodiment, the bumpiness of the first road section may be input into a preset formula to determine the height of the air suspension after adjustment.

[0107] In one embodiment, under the same bumpiness level, the vehicle may also consider the vehicle model when controlling the height of the air suspension.

[0108] For example, as shown in Table 3, under the same bumpiness, the larger the volume of the vehicle is, the greater the height that the air suspension can be raised.

[0109] Table 3

[0110] Model Air suspension height Small car +10mm Sport Utility Vehicle +20mm truck +30mm

[0111] In one embodiment, under the same bumpiness, the vehicle may also consider the load of the vehicle when controlling the height of the air suspension, that is, the higher the load of the vehicle, the greater the height of the air suspension may be raised.

[0112] In one embodiment, when the bumpiness of the first road section is greater than or equal to the first preset threshold, but the user's first input indicates not to adjust the height of the air suspension, the vehicle can control the height of the air suspension to remain unchanged, and save the corresponding relationship between the user's identification information and the third preset threshold, wherein the third preset threshold is greater than the first preset threshold. In this way, since different users have different tolerances for the bumpiness of the road, when the user's tolerance is higher, the preset threshold needs to be set higher, so that while improving the intelligence of the vehicle, the user's driving experience can also be further improved.

[0113] For example, the first preset threshold may be set to ±1 mm, and the third preset threshold may be set to ±3 mm.

[0114] Optionally, when the vehicle obtains the degree of bumpiness of the second road section where the vehicle is located when the user is in the vehicle, and the degree of bumpiness of the second road section is greater than or equal to the third preset threshold, the vehicle can control the prompting device to prompt the user to adjust the height of the air suspension. That is, when the degree of bumpiness of the second road section is greater than the first preset threshold and less than the third preset threshold, the vehicle does not control the prompting device to prompt the user to adjust the height of the air suspension.

[0115] The vehicle can interact with other devices to learn whether the bumpiness of the first road section meets preset conditions.

[0116] In one embodiment, the vehicle can send the bumpiness of the first road section to the cloud device, and the cloud device determines whether the bumpiness of the first road section meets the preset condition. When the bumpiness of the first road section meets the preset condition, the cloud device can send the first information to the vehicle to indicate that the bumpiness of the first road section meets the preset condition. After receiving the first information, the vehicle can control the prompt device to prompt the user to adjust the height of the air suspension based on the first information. In this way, the vehicle does not need to judge whether the bumpiness of the first road section meets the preset condition, thereby saving the computing resources of the vehicle.

[0117] Optionally, the cloud device may include: a server, a network device, or a base station.

[0118] Figure 3 It is a schematic flow chart of another control method provided in an embodiment of the present application. Method 300 may be a detailed introduction of steps S201 to S202 of method 200. Method 300 may include steps S301 to S307.

[0119] S301, detecting that the vehicle is traveling on a bumpy road.

[0120] S302, controlling the acceleration and height sensors to sense the bumpiness of the road surface.

[0121] In one embodiment, the bumpiness of the road surface may be sensed based on the following formula.

[0122]

[0123] in, is the derivative of the road surface vertical displacement excitation, that is, the velocity value of the excitation; q(t) is the road surface vertical displacement excitation (which can be measured by a height sensor); v is the vehicle speed; G q (n 0 ) is the geometric mean of the road roughness coefficient; W 0 (t) is the acceleration of the vehicle (which can be measured by an acceleration sensor).

[0124] Through the above formula, we can get G q (n 0 ) and based on the specific value of G q (n 0 ) determines the degree of bumpiness of the road surface.

[0125] Optionally, G q (n 0 ) can correspond to the grade of the road surface, that is, the higher the grade of the road surface, the higher the G q (n 0 ) is also larger.

[0126] S303: Determine the height of the air suspension that needs to be raised.

[0127] Optionally, the vehicle may determine the height of the air suspension that needs to be lifted based on the corresponding relationships in Table 1, Table 2, and Table 3.

[0128] S304, voice asks the user whether the height of the air suspension needs to be increased.

[0129] Specifically, after detecting the user's first input, it can be determined whether to increase the height of the air suspension based on the first input, that is, when the first input is used to indicate raising the height of the air suspension, step S305 can be executed to raise the height of the air suspension, otherwise the vehicle may not raise the height of the air suspension.

[0130] Optionally, the user's first input may be voice input, key input or touch screen input.

[0131] S305, raise the height of the air suspension.

[0132] For example, Figure 4 As shown, before the air suspension height is raised, the approach angle of the vehicle may be less than 18.8 degrees, and the departure angle may be less than 20.8 degrees. After executing step S305, the approach angle of the vehicle may be greater than or equal to 18.8 degrees, and the departure angle may be greater than or equal to 20.8 degrees. In this way, when the vehicle is traveling on a bumpy road, the driving comfort of the user and the passability of the vehicle can be improved.

[0133] S306 , asking the user whether to memorize the height of the air suspension.

[0134] Exemplarily, after detecting a user's voice input, if the voice input is used to instruct the vehicle to memorize the height of the air suspension, the vehicle may memorize the height of the air suspension, otherwise the vehicle will not memorize the height of the air suspension.

[0135] S307, passing the same section again, directly raising the height of the air suspension.

[0136] Exemplarily, the height of the air suspension is the second height before lifting and the first height after lifting, and the first height is greater than the second height. In step S306, the vehicle memorizes the value of the first height. Then, in step S307, when the vehicle passes the same section again, the vehicle can directly raise the height of the air suspension to the first height without having to interact with the user by voice again.

[0137] Alternatively, in method 300 , raising the height of the air suspension may also be directly replaced by increasing the height of the vehicle. The height of the vehicle may be, for example, the height between the wheel center and the wheel arch of the wheel.

[0138] In the embodiment of the present application, the vehicle can sense the bumpiness of the road through the acceleration sensor and the height sensor, and then prompt the user to adjust the height of the air suspension based on the bumpiness of the road. In this way, the safety of the vehicle driving on bumpy roads and the driving comfort of the user can be improved. In addition, by confirming with the user whether to memorize the height of the air suspension through voice interaction, the user's human-computer interaction experience can be enhanced, which reflects the intelligence of the vehicle.
