Description

Technical Field

[0001] This disclosure relates to the field of vehicle intelligent control technology, and in particular to a vehicle control method, device, equipment, vehicle, and storage medium. Background Technology

[0002] With the development of technology, automobiles are becoming increasingly intelligent, and people's demands for cars are constantly increasing, especially the requirements for the comfort of car use. This is mainly because cars are people's primary means of transportation, and the time people spend in cars is also constantly increasing. For example, people spend a lot of time resting and taking naps in their cars.

[0003] When people rest in a car, they usually lie on the car mattress inside the cabin. However, under normal driving conditions, the floor of the vehicle cabin is generally lower in the front and higher in the back, or when the vehicle is parked on a sloped surface, the floor of the cabin is not level. This causes the car mattress placed at the bottom of the cabin to be in a non-level position.

[0004] Thus, since people are very sensitive to angles when they are sleeping, the non-horizontal state of the car mattress will make the user's sleeping experience worse. Summary of the Invention

[0069] The vehicle control method provided in the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings.

[0070] Figure 1This is a flowchart illustrating a vehicle control method according to an embodiment of the present disclosure. This embodiment is applicable to situations involving adjusting the level of a vehicle mattress. The vehicle control method is executed by a vehicle control device. This vehicle control device can be implemented using software and / or hardware, and can be configured in an electronic device.

[0071] For example, the electronic device may be a mobile terminal, a fixed terminal, or a portable terminal, such as a mobile phone, site, unit, device, multimedia computer, multimedia tablet, internet module, communicator, desktop computer, laptop computer, notebook computer, netbook computer, tablet computer, personal communication system (PCS) device, personal navigation device, personal digital assistant (PDA), audio / video player, digital camera / camcorder, positioning device, television receiver, radio broadcast receiver, e-book device, gaming device, or any combination thereof, including accessories and peripherals of these devices, or any combination thereof.

[0072] For example, the electronic device can be a server, which can be a physical server or a cloud server. The server can be a single server or a server cluster.

[0073] Specifically, such as Figure 1 As shown, the vehicle control method provided in this embodiment mainly includes steps S101-S104.

[0074] S101. When the vehicle is in sleep mode, acquire human posture information.

[0075] In this embodiment of the disclosure, the sleep mode can be understood as a mode in which the vehicle enters a leisure state after parking. The leisure state is mainly used to provide users with a state of leisure, entertainment, sleep, etc. In the sleep mode, users can not only listen to music and watch videos, but also place a mattress inside the vehicle cabin so that users can rest or sleep on the mattress.

[0076] In one embodiment of this disclosure, in response to receiving a vehicle mode switching command, the vehicle mode is switched from non-sleep mode to sleep mode, controlling the vehicle to operate in sleep mode. Non-sleep mode can be a normal usage mode, karaoke mode, etc.

[0077] In this embodiment of the disclosure, after the vehicle switches from driving mode to parked mode, it is detected whether a vehicle mode switching command input by the user has been received. This command can be input by the user via a click, voice, or gesture. For example, if the user inputs the voice command "Please switch the mode to sleep mode," the vehicle mode switching command is successfully input.

[0078] In one specific implementation, the vehicle mode switching command can be a command input by the user through the vehicle's central control display screen. Specifically, the user can bring up the mode switching interface by clicking, swiping, or using voice commands, and display this interface on the central control display screen. Then, the user can input the mode switching command through the displayed interface. Once the vehicle receives the mode switching command, it can execute the corresponding mode switching operation.

[0079] In one possible implementation, the vehicle mode switching command can also be input by the user through a designated terminal connected to the vehicle. Specifically, the vehicle and the designated terminal can be connected via Bluetooth. When the terminal receives a user-input command to open a program, it opens the designated application and displays its interface. This designated application can be a dedicated application for managing the vehicle. After displaying the application's interface on the terminal, the terminal can receive the vehicle mode switching command input by the user. Finally, the terminal can send the received vehicle mode switching command to the vehicle and instruct the vehicle to perform a mode switching operation according to the command.

[0080] In this embodiment of the disclosure, the human posture information can be understood as representing a certain action or posture that the human body is currently performing. For example, human posture may include sitting posture, kneeling posture, bending posture, sleeping posture, etc.

[0081] In one embodiment of this disclosure, obtaining human posture information includes: acquiring an image including a human body through an image acquisition device inside the vehicle to obtain an acquired image; and identifying the human body region included in the acquired image to obtain human posture information.

[0082] The vehicle is equipped with an image acquisition device, which can be a camera. The camera is installed in a position that allows it to capture a complete, unobstructed view of the vehicle-mounted mattress.

[0083] In one embodiment of this disclosure, image information corresponding to the human body is acquired, the image information is identified to obtain skeletal key points in the human body, and the obtained skeletal key points are connected to obtain the posture information of the human body.

[0084] In one embodiment of this disclosure, image information corresponding to a human body is obtained, wherein the image information includes a depth value. After performing three-dimensional modeling on the image information, a three-dimensional model corresponding to the human body is obtained. The coordinate values ​​of the three-dimensional model in three-dimensional space can be used as human body posture information.

[0085] S102. Determine whether the human posture information meets the sleeping posture conditions based on the relative positional relationship of human body parts.

[0086] The relative positional relationship of human body parts refers to the relative positional relationship between various parts of the body when the body is in a sleeping position, such as the relative positional relationship between the head and feet, the ratio of head length to body length, etc.

[0087] In one embodiment of this disclosure, image information corresponding to the human body is acquired, and the image information is identified to obtain the position of the human head, the length of the human head, and the length of the human body. The body length refers to the length of the torso and head combined, that is, the length from the top of the human head to the bottom of the feet. The head length refers to the length from the top of the human head to the chin.

[0088] In one embodiment of this disclosure, after obtaining human posture information, it is necessary to determine whether the human posture information meets the sleeping posture conditions. The sleeping posture can be any lying position such as supine, side-lying, or prone. The sleeping posture conditions refer to the human posture information obtained when the user is lying on the car mattress, which meets the preset relative positional relationship of human body parts.

[0089] In one embodiment of this disclosure, determining whether the human posture information meets the sleeping posture conditions based on the relative positional relationship of human body parts includes: determining whether the shortest distance between the human head position and the vehicle mattress is less than a preset distance; when the shortest distance is less than the preset distance, calculating the ratio of the human head length to the human body length to obtain the head-to-body ratio; and when the head-to-body ratio is within a preset range, determining that the human posture information meets the sleeping posture conditions.

[0090] In this embodiment of the disclosure, the preset distance can be 0. Specifically, determining whether the shortest distance between the human head and the vehicle-mounted mattress is less than the preset distance can be understood as determining whether the human head is in contact with the vehicle-mounted mattress. When the shortest distance is less than the preset distance, it means that the human head is in contact with the vehicle-mounted mattress.

[0091] Furthermore, the preset range is obtained based on experience, generally between 1 / 7 and 1 / 9, meaning that for most people in a sleeping position, the ratio of their head to their body is between 1 / 7 and 1 / 9. Further, when the human head is in contact with the car mattress and the ratio of the human head length to the human body length is within this range of 1 / 7 to 1 / 9, the human body is determined to meet the sleeping posture requirements; if it is not within this range, the human posture information is determined to not meet the sleeping posture requirements.

[0092] In this embodiment, if the human posture information meets the sleeping posture conditions, step S102 is executed. If the human posture information does not meet the sleeping posture conditions, the human posture information is acquired again after a preset interval to determine whether the human posture information meets the sleeping posture conditions. In this embodiment, when the human posture information does not meet the sleeping posture conditions, such as in a sitting position, the human body is not particularly sensitive to horizontal states in a sitting position, meaning the user may not feel the discomfort caused by a non-horizontal state. In this case, the vehicle suspension can be left unadjusted, avoiding frequent suspension adjustments that could affect the suspension's lifespan.

[0093] S103. When the human posture information meets the sleeping posture conditions, determine whether the vehicle mattress is in a horizontal state, wherein the vehicle mattress is placed inside the cabin of the vehicle.

[0094] In this embodiment of the disclosure, since the position of the image acquisition device installed inside the vehicle is fixed, that is, when the human posture information included in the image acquired by it meets the sleeping posture conditions, the default is that the vehicle mattress is placed inside the cabin and the human body is lying on the vehicle mattress.

[0095] The term "horizontal" in this context can be understood as the upper surface of the vehicle mattress being parallel to a horizontal plane. In one embodiment of this disclosure, determining whether the vehicle mattress is horizontal includes: acquiring the current tilt angle information of the vehicle; determining whether the current tilt angle information is within a preset angle range; if the current tilt angle information is within the preset angle range, then determining that the vehicle mattress is horizontal; if the current tilt angle information is not within the preset angle range, then determining that the vehicle mattress is not horizontal.

[0096] The tilt angle information may include pitch angle and roll angle. Further, the pitch angle may be the vehicle's forward / backward tilt angle, and the roll angle may be the vehicle's left / right tilt angle. The preset angle range can be set according to the user's perception of the horizontal plane; optionally, the preset angle range is 10 to 15 degrees.

[0097] In one embodiment of this disclosure, obtaining the current tilt angle information of the vehicle includes: obtaining the current tilt angle information of the vehicle through the vehicle's built-in gyroscope angle sensor.

[0098] In this embodiment, the built-in gyroscope angle sensor can detect the tilt angle information corresponding to the current vehicle state. The built-in gyroscope angle sensor can be integrated into the vehicle during the manufacturing process or installed by the user after the vehicle leaves the factory; this embodiment does not limit the installation time or method of the built-in gyroscope.

[0099] In one embodiment of this disclosure, obtaining the current tilt angle information of the vehicle includes: acquiring a detection image including the vehicle mattress through an image acquisition device inside the vehicle, comparing and analyzing the detection image and a preset image to obtain the current tilt angle information of the vehicle, wherein the preset image is acquired by the image acquisition device, and the vehicle mattress included in the preset image is in a horizontal state.

[0100] In this embodiment of the disclosure, the preset image refers to the image captured by the image acquisition device when the vehicle-mounted mattress is in a horizontal position. The currently captured detection image is analyzed and compared with the preset image to obtain the current tilt angle information.

[0101] In this embodiment of the disclosure, the current tilt angle information is calculated based on the first camera coordinates of a key point (e.g., the upper left corner of the vehicle mattress) in the detection image, the second camera coordinates of the key point in the preset image, and the camera coordinate origin.

[0102] S103. When the vehicle mattress is not in a horizontal position, adjust the vehicle suspension so that the vehicle mattress is in a horizontal position.

[0103] In the embodiments disclosed herein, such as Figure 2 As shown, the upper surface of the car mattress (the plane that directly contacts the human body) is parallel to the bottom of the vehicle cabin, and the horizontal state of the upper surface of the car mattress changes in real time with the horizontal state of the bottom of the vehicle cabin. Therefore, the height of the vehicle suspension can be adjusted to change the horizontal state of the bottom of the vehicle cabin, thereby adjusting the horizontal state of the car mattress.

[0104] In this embodiment of the disclosure, the vehicle suspension can be any one of MacPherson independent suspension, multi-link independent suspension, double wishbone independent suspension, etc., and this embodiment of the disclosure does not specifically limit the type of vehicle suspension.

[0105] In this embodiment of the disclosure, when the front end of the vehicle is higher than the rear end, the height of the rear wheel suspension can be increased, and / or the height of the front wheel suspension can be decreased. When the front end of the vehicle is lower than the rear end, the height of the rear wheel suspension can be decreased, and / or the height of the front wheel suspension can be increased. Similarly, the height of the left wheel suspension and / or the height of the right wheel suspension can be adjusted according to the status information of the vehicle mattress.

[0106] In this embodiment, the rear suspension and front suspension can be adjusted simultaneously or sequentially, and this embodiment does not specifically limit the adjustment. Furthermore, during the suspension adjustment process, the status information of the vehicle mattress can be acquired in real time to determine whether the vehicle mattress is in a level state. When the vehicle mattress is detected to be in a level state, the suspension adjustment is stopped.

[0107] In one embodiment of this disclosure, adjusting the vehicle suspension includes: querying the correspondence between angle information and adjustment parameters based on the current tilt angle information; using the queried adjustment parameters as target adjustment parameters for the suspension; and adjusting the vehicle suspension according to the target adjustment parameters.

[0108] The adjustment parameters mainly include suspension indicators and adjustment ranges. The suspension indicators specify which suspension position needs adjustment, and the adjustment range is the degree to which the suspension needs to be raised or lowered. In this embodiment, the correspondence between angle information and adjustment parameters is pre-stored; for example, the adjustment parameters corresponding to a pitch angle of 10° and a roll angle of 15°. Furthermore, the above correspondence can be obtained through multiple experiments, and during vehicle use, the correspondence can be continuously learned and optimized to make the target adjustment parameters more accurate.

[0109] In one embodiment of this disclosure, the target adjustment parameter includes a target suspension identifier and a target adjustment range; adjusting the vehicle suspension according to the target adjustment parameter includes: controlling the vehicle suspension corresponding to the target suspension identifier to adjust according to the target adjustment range.

[0110] In this embodiment of the disclosure, the target suspension indicator is used to indicate the suspension that needs adjustment. For example, controlling the suspension corresponding to the left front wheel to rise by 2 cm; controlling the suspension corresponding to the right rear wheel to fall by 3 cm, etc.

[0111] This disclosure provides a vehicle control method comprising: acquiring human posture information when the vehicle is in sleep mode; determining whether the human posture information meets sleeping posture conditions based on the relative positional relationship of human body parts; determining whether the vehicle mattress is in a horizontal position when the human posture information meets the sleeping posture conditions, wherein the vehicle mattress is placed inside the vehicle's cabin; and adjusting the vehicle suspension to make the vehicle mattress horizontal when the vehicle mattress is not horizontal. This disclosure, by determining whether the user is in a sleeping posture during sleep mode, and adjusting the vehicle suspension to adjust the vehicle's posture when the user is in a sleeping posture, thereby adjusting the vehicle mattress to make it horizontal, provides a more comfortable sleep experience for the person lying on the mattress.
