Obviously, for those skilled in the art, other drawings can also be obtained without creative labor based on these drawings.

[0028] Many specific details are set forth in the following description in order to provide a thorough understanding of the present disclosure. However, the present disclosure can be practiced according to other embodiments that do not require some of the specific details described below. It is understood that the present disclosure is well suited to implementing embodiments like those described below, but the description is, of course, not intended to limit the scope of the present disclosure.

[0029] Some of the terms or phrases that appear in the description of the embodiments of the present disclosure are explained as follows: Vehicle: The vehicle proposed in the embodiments of the present disclosure includes but is not limited to a private car, a passenger transport operation vehicle, a freight transport operation vehicle, or other types of vehicles. For example, the vehicle can be a sedan, a sport utility vehicle (SUV), or a multi-purpose vehicle (MPV). Exemplarily, the vehicle is provided with sensors for collecting the driving state of the vehicle.

[0030] Inertial measurement unit (IMU): The inertial measurement unit is internally provided with an accelerometer, a gyroscope, and a magnetometer, which can measure the linear acceleration change and angular velocity change of the vehicle in different directions, so as to perceive the motion state and attitude state of the vehicle in real time. Through this data, the jounce index of the vehicle can be calculated.

[0031] Cabin: The cabin proposed in the embodiments of the present disclosure refers to the space in the vehicle for people to sit. For example, the cabin can be a driver's cabin or a passenger cabin. Exemplarily, various sensors for detecting the action feature information of the people in the cabin can be arranged in the cabin. The types and purposes of the sensors that can be arranged in the cabin are exemplified as follows: TOF (Time of Flight) camera: The TOF camera can capture the three-dimensional coordinates of the hands of the people in the cabin, the hand movement speed, the hand movement acceleration, the hand movement direction, and the motion trajectory curvature, etc. in real time.

[0032] DMS (Driver Monitoring System) camera: The DMS camera can detect the visual focus of the people in the cabin and determine whether the visual focus is focused on a certain area.

[0033] Seat pressure sensor: The seat pressure sensor can perceive the sitting posture of the people and determine whether the body of the people is tilted or shaken.

[0034] The visual sensor can be a camera. The visual sensor can collect image information of a person or an object in the cabin, and perform image recognition on the collected image information based on an image recognition algorithm or an artificial intelligence model, so as to recognize information such as identity, age, and mental state of the person in the cabin.

[0035] The vehicle display screen includes, but is not limited to, a display screen of a main driving position, a central control display screen, a liquid crystal instrument, a head-up display (HUD), an entertainment display screen of a co-driver, a chair back display screen, a rear row ceiling display screen, or a movable terminal display screen. Exemplarily, the vehicle display screen is a touch display screen.

[0036] The function control is a graphical control displayed on the vehicle display screen. The function control is associated with at least one function program. Exemplarily, the function program associated with the function control can control a specific device on the vehicle to work, or run a specific application program and control the vehicle display screen to display the program interface of the application program. For example, the function control can control the opening and closing of a window or a sunroof of the vehicle under the touch operation of the person. For example, the function control can control the movement of the vehicle seat, the change of the height, or the change of the backrest angle under the touch operation of the person. For example, the function control can start navigation, stop navigation, or change the navigation destination under the touch operation of the person. For example, the function control can make or hang up a call under the touch operation of the person.

[0037] The GUI framework is a graphical user interface (GUI) framework. The GUI framework is a software basic platform responsible for interface layout, control rendering, and user interaction event management in the vehicle system, which determines how buttons, menus, and touch operations are displayed and processed on the screen.

[0038] Before the embodiments of the present disclosure are described in detail, the technical background related to the present disclosure is described herein, so that those skilled in the art can have a clearer understanding of the embodiments of the present disclosure.

[0039] In the related art, with the development of vehicle intelligence, the vehicle has more and more functions. These functions are often integrated into a vehicle display screen such as a vehicle machine display screen or a central control display screen. The driver or passenger in the cabin can control one or more function controls displayed on the vehicle display screen through touch operation to control the functions of the vehicle. For example, adjusting the air conditioning temperature, adjusting the seat, opening and closing the window, setting the navigation, or making or hanging up a call.

[0040] When performing touch operation, the person in the cabin only needs to touch the function control by hand, such as the index finger, to control the vehicle system to run the function program corresponding to the function control.

[0041] During vehicle operation, passengers may unconsciously move their hands due to vibrations or inertia, especially when driving on bumpy roads, making sharp turns, or braking aggressively. These unconscious movements could lead to accidental touchscreen activation. If a passenger accidentally touches a critical function, such as adjusting the driver's seat position, adjusting navigation, switching on / off autopilot or driver assistance features, activating / deactivating child safety locks, or making a phone call, it could affect the driver's ability to drive normally and thus compromise driving safety.

[0042] In view of this, the present disclosure provides a vehicle control method, the vehicle including a cabin, an in-vehicle display screen provided in the cabin, the in-vehicle display screen being used to display at least one functional control.

[0043] Figure 1 This is a schematic diagram of a display interface for an in-vehicle display screen provided in an embodiment of this disclosure, such as... Figure 1 As shown, the display interface of the vehicle-mounted display screen 10 displays function controls 12. Function controls 12 are associated with at least one function program. For example, Figure 1 The shown function control 12 is associated with the navigation function. Among them, some important function programs, such as communication function programs (e.g., making phone calls, sending messages), driving control function programs (e.g., switching driving modes, turning on / off assisted driving), and safety function programs (e.g., turning on / off child locks, adjusting seat position), may affect driving safety if accidentally touched.

[0044] In the following description, this disclosure will use the security control of the aforementioned important related functional program as an example for explanation.

[0045] Figure 2 A flowchart of a vehicle control method provided in this disclosure embodiment is shown below. Figure 2 As shown, the method includes: S202, acquire motion characteristic information of occupants and driving characteristic information of the vehicle.

[0046] In this embodiment of the disclosure, the occupants of the cockpit include the driver and passengers. Sensors for acquiring motion characteristic information of the occupants are installed in the cockpit. Exemplarily, a TOF camera, a DMS camera, and a seat pressure sensor are installed in the cockpit.

[0047] Motion feature information can reflect whether a person's current action is conscious or unconscious. For example, when a person's hand movement trajectory matches the area where their gaze is focused, it indicates that the person's hand movement is most likely a conscious action.

[0048] The vehicle is provided with a sensor for collecting driving feature information. Exemplarily, the vehicle is provided with an on-board inertial measurement unit. The on-board inertial measurement unit can detect the acceleration and angular velocity of the vehicle, and through the acceleration and angular velocity, it can be determined whether the vehicle is in a jolt state.

[0049] In S204, an operation probability is determined according to the action feature information and the driving feature information.

[0050] The operation probability is the probability of the person in the cabin operating the function control.

[0051] In the embodiments of the present disclosure, the operation probability of the person is determined by combining the action feature of the corresponding person and the driving feature of the current vehicle. According to the action feature information of the person, it can be determined whether the person in the cabin has the intention to actively touch the function control displayed on the on-board display screen.

[0052] Exemplarily, it is assumed that the action feature information includes hand movement information and line of sight focus information of the person. The hand movement information of the person can represent what position the person's hand is stretching to. The line of sight focus information of the person can represent what position the person's eyes are looking at. If the position to which the hand of the passenger or the driver is stretching is the same as the position to which the eyes are looking, it means that the hand movement of the person is a purposeful active action. If the position to which the hand is stretching is different from the position to which the eyes are looking, it means that the hand movement of the person may be an unconscious action.

[0053] According to the driving feature information of the vehicle, it can be determined whether the vehicle is in a state that will affect the body movement of the person in the vehicle, such as jolt, rapid acceleration, rapid deceleration, or turning a bend. If the vehicle is driving smoothly, the hand movement of the person in the vehicle cabin will not be affected or will be slightly affected by the driving of the vehicle. Therefore, the possibility of the person mistakenly touching the on-board display screen due to the driving factors of the vehicle is relatively small.

[0054] If the vehicle is in a driving state such as jolt, rapid acceleration, rapid deceleration, or turning a bend, the person in the vehicle cabin will be affected by factors such as inertia. At this time, the hand movement of the person may deviate from the original movement track due to the influence of the driving state of the vehicle, or may be unconsciously swinging with the jolt of the vehicle. At this time, the possibility of the person mistakenly touching the function control displayed on the on-board display screen will be larger.

[0055] Therefore, by combining the action feature of the corresponding person and the driving feature of the current vehicle, it can be more accurately predicted whether the person in the vehicle has the real intention to touch and control the function control. The higher the operation probability, the more likely it is that the person in the vehicle really wants to touch and control the function control. The lower the operation probability, the higher the possibility that the person in the vehicle unconsciously approaches the function control due to external influences.

[0056] S206, in a case where the operation probability is less than the first probability threshold, controlling the vehicle-mounted display screen to enter a locked state.

[0057] In the locked state, the vehicle-mounted display screen shields the touch operation on the function control.

[0058] In the embodiments of the present disclosure, if it is detected that the operation probability of the person in the cabin is less than the first probability threshold, it is determined that the behavior of the person's hand approaching the function control on the vehicle-mounted display screen is an unconscious behavior, and the possibility of misoperation is relatively large. At this time, the vehicle-mounted display screen is controlled to enter a locked state. After entering the locked state, the vehicle-mounted display screen will not respond to the function control. That is, even if the person touches the function control, the function program corresponding to the function control will not be run, so as to avoid the situation that the driving safety is affected due to the misoperation of the function control of the important function program.

[0059] Exemplarily, the operation probability is a rational number between 0 and 1. Exemplarily, the range of the probability threshold is 0.1-0.5.

[0060] In the embodiments of the present disclosure, when the person in the cabin, including the driver and the passenger, is likely to perform the touch operation on the function control displayed by the vehicle-mounted display screen, the operation probability of the person is determined by combining the motion feature of the corresponding person and the driving feature of the current vehicle. The operation probability can truly reflect the intention of the person to interact with the function control. When the operation probability of the person is lower than the expected probability threshold, it indicates that the person has no intention to interact with the function control, which may be caused by the vehicle bumping or inertia, etc. At this time, the touch operation area of the vehicle-mounted display screen associated with the function control is locked. Even if the person's hand accidentally touches the function control, the function program of the function control will not be triggered, so as to effectively reduce the situation that the person accidentally touches the vehicle-mounted touch screen during the driving of the vehicle.

[0061] In some embodiments of the present disclosure, optionally, before determining the operation probability according to the motion feature information and the driving feature information, the method further comprises: obtaining hand position information of the person in the cabin; determining distance information between the hand of the person in the cabin and the vehicle-mounted display screen according to the hand position information; in a case where the distance information is less than a first distance threshold, performing the step of determining the operation probability according to the motion feature information and the driving feature information.

[0062] In the embodiments of the present disclosure, the vehicle-mounted display screen is generally a touch screen. The person can run the function program corresponding to the function control by touching the function control displayed on the vehicle-mounted display screen through hand movement. Therefore, when the person's hand is far away from the vehicle-mounted display screen, the function of the function control will not be misoperated.

[0063] Therefore, the embodiment of the present disclosure monitors the hand position information of the person in real time through the sensor in the cabin, such as a TOF camera, to obtain the spatial coordinates of the hand of the person in the cabin coordinate system. At the same time, the position of the vehicle display screen in the cabin is known, that is, the spatial coordinates of the vehicle display screen in the cabin coordinate system are known. Therefore, the distance information between the hand of the person and the vehicle display screen can be calculated according to the hand position information of the person.

[0064] If the distance information between the hand of the person and the vehicle display screen is less than the first distance threshold, it is judged that the distance between the hand of the person and the vehicle display screen is close, and there is a possibility of false touch. At this time, the step of determining the operation probability according to the action feature information and the driving feature information in the above embodiment is performed, and it is judged whether the vehicle display screen needs to be locked according to the determined operation probability.

[0065] If the distance between the hand of the person and the vehicle display screen is greater than or equal to the first distance threshold, it is judged that the distance between the hand of the person and the vehicle display screen is far, and the possibility of false touch is low. At this time, the step of determining the operation probability according to the action feature information and the driving feature information in the above embodiment does not need to be performed, and the calculation power consumption of the intelligent cabin is reduced.

[0066] Exemplarily, the first distance threshold ranges from 15 cm to 50 cm. Exemplarily, the first distance threshold is 25 cm.

[0067] The embodiment of the present disclosure detects the distance between the hand of the person in the cabin and the vehicle display screen, judges whether the operation intention of the person needs to be determined according to the detection result, and locks the vehicle display screen based on the operation intention. Therefore, in the case of false touch risk, false touch caused by the unconscious movement of the hand of the person due to external factors can be effectively prevented, and in the case of low false touch risk, the calculation power resources of the intelligent cabin can be saved.

[0068] In some embodiments of the present disclosure, optionally, after the operation probability is determined according to the action feature information and the driving feature information, the method further comprises: In the case that the operation probability is greater than or equal to a second probability threshold, and the distance information is less than or equal to a second distance threshold, the jolt index of the vehicle is determined according to the driving feature information of the vehicle; In the case that the jolt index is greater than a jolt threshold, the function program corresponding to the function control of the vehicle display screen is controlled to run; Wherein, the second probability threshold is greater than the first probability threshold, and the second distance threshold is less than the first distance threshold.

[0069] In the embodiments of the present disclosure, the first probability threshold is used to determine whether there is a greater risk of false touch. When the operation probability is less than the first probability threshold, the person has a greater probability of not having the intention to operate the function control. The second probability is used to determine whether the person has a greater probability of having the intention to operate the function control. When the operation probability is greater than the second probability threshold, it indicates that the person is probably going to perform a touch control operation on the function control. At this time, the distance between the person's hand and the vehicle-mounted display screen is further acquired.

[0070] If the distance between the person's hand and the vehicle-mounted display screen is less than the second distance threshold, it indicates that the person's hand has been very close to the vehicle-mounted display screen, that is, the touch operation is about to be completed. At this time, the jolt index of the vehicle is determined according to the driving feature information of the vehicle.

[0071] The jolt index is used to measure whether the jolt state of the current vehicle is likely to affect the touch control operation of the person. When the jolt degree of the vehicle is high, the body jolt will be transmitted to the person's body through the seat, which will cause the person's hand to appear uncontrollable "trembling", which will seriously affect the accuracy of the person's touch control operation and cause the false operation of touching the non-target function control.

[0072] In this regard, when the operation probability is greater than or equal to the second probability threshold, the distance information is less than or equal to the second distance threshold, and the jolt index is greater than the jolt threshold, the function program corresponding to the function control with the operation probability greater than the second probability threshold is run in advance according to the recognized operation probability. This can help the person quickly complete the touch control operation he wants to perform and reduce the influence of the body jolt on the person's touch control operation.

[0073] Exemplarily, the second probability threshold ranges from 0.5 to 0.9.

[0074] Exemplarily, the second distance threshold ranges from 3 cm to 10 cm.

[0075] Exemplarily, the acceleration and angular velocity of the vehicle can be acquired by the vehicle-mounted inertial measurement unit, and the acceleration variance and angular velocity variance are determined. The jolt index is calculated according to the acceleration variance and angular velocity variance. Exemplarily, the jolt index can be calculated by the following formula: ; Wherein, D is the jolt index, a is the acceleration variance, and ω is the angular velocity variance.

[0076] Exemplarily, assuming that the first probability threshold is 0.4, the second probability threshold is 0.6, the first distance threshold is 30 cm, the second distance threshold is 8 cm, and the jolt threshold is D1. When it is detected that the distance between the hand of the person and the vehicle-mounted display screen is less than 30 cm, the operation probability of the person on one or more function controls displayed on the current vehicle-mounted display screen is determined respectively. Assuming that the operation probability of the person on the function control of "opening the window" is d, when the operation probability d is less than 0.4, the vehicle-mounted display screen is set to a locked state, and the touch operation on the function control of "opening the window" is shielded.

[0077] When the operation probability d is greater than 0.4 and less than 0.6, no processing is performed. When the operation probability d is greater than 0.6, if the distance between the hand of the person and the vehicle-mounted display screen is less than 8 cm, and the jolt index of the vehicle is greater than the jolt threshold D1, the function program of the function control of "opening the window" is directly run, and at this time, the vehicle machine system controls the vehicle to open the corresponding window.

[0078] The embodiments of the present disclosure can predict the function control that the person in the cabin wants to control when the vehicle jolts, and run the function program of the function control in advance when the operation probability of the person on the function control is greater than the second probability threshold, thereby improving the success rate of the touch operation of the person under the condition of vehicle jolting.

[0079] In some embodiments of the present disclosure, optionally, after controlling the vehicle-mounted display screen to enter the locked state, the method further comprises: determining second distance information between the hand of the person in the cabin and the vehicle-mounted display screen according to the hand position information; controlling the vehicle-mounted display screen to exit the locked state in the case that the second distance information is greater than a third distance threshold; wherein the third distance threshold is greater than or equal to the first distance threshold.

[0080] In the embodiments of the present disclosure, when it is detected that the distance between the hand of the person and the vehicle-mounted display screen is less than the first threshold, the operation probability of the person on the function control displayed by the vehicle-mounted display screen is judged. When the operation probability of the person on the function control is less than the first probability threshold, the vehicle-mounted display screen is controlled to enter a locked state, at which time the vehicle-mounted display screen automatically shields the touch operation on the function control, preventing the occurrence of a false touch.

[0081] Thereafter, the position information of the hand of the person in the cabin is continuously concerned by a TOF camera and other sensors, and the second distance information between the hand of the person and the vehicle-mounted display screen is calculated in real time.

[0082] When the second distance information between the hand of the person and the vehicle-mounted display screen is detected to be greater than the third distance threshold, it indicates that the hand of the person is far away from the vehicle-mounted display screen, and the risk of false touch is low. At this time, the vehicle-mounted display screen is controlled to exit the locked state, and the person in the cabin can normally perform touch operation on the function control.

[0083] Exemplarily, the third distance threshold ranges from 20 cm to 60 cm. Exemplarily, the third distance threshold is 30 cm.

[0084] After locking the vehicle-mounted display screen to shield the touch operation on the function control, the embodiment of the present disclosure continues to monitor the position of the hand of the person. When it is detected that the position of the hand of the person is far away from the vehicle-mounted display screen, it indicates that there is no risk of false touch, and the vehicle-mounted display screen is controlled to automatically exit the locked mode, thereby realizing automatic switching of the locked mode. Through the embodiment of the present disclosure, the influence of the normal touch operation of the person on the vehicle-mounted display screen can be reduced while effectively reducing the false touch problem of the vehicle-mounted display screen.

[0085] In some embodiments of the present disclosure, optionally, before determining the operation probability according to the action feature information and the driving feature information, the method further comprises: obtaining appearance feature information of the person in the cabin; determining the age of the person in the cabin according to the appearance feature information; adjusting the probability threshold according to the age of the person in the cabin.

[0086] In the embodiment of the present disclosure, people of different ages have different control abilities of limbs and different degrees of influence from external factors such as vehicle jolt. For the elderly, the control of the hand is reduced due to the decline in physical fitness, and they are easily affected by external factors such as jolt. For middle-aged users, the control of the hand is higher, and they are not easily affected by external factors such as jolt. For children of a younger age, the risk of false touch is higher due to the hyperactivity of children.

[0087] To this end, the embodiment of the present disclosure obtains the age of the person in the cabin, and when performing false touch protection, different ages of people can all receive consistent false touch protection by adjusting the probability threshold corresponding to different ages. On the one hand, false touch can be reduced, and on the other hand, the interference with normal touch operation can be reduced.

[0088] Exemplarily, the appearance feature information of the person in the cabin can be obtained by a visual sensor or the like. For example, the face image of the person in the cabin is captured. By image recognition on the face image, the approximate age of the corresponding person can be obtained.

[0089] Exemplarily, the age of the person can be determined according to the user information input by the user when the vehicle is parked.

[0090] For example, for the older personnel, such as personnel older than 60 years old. Since the shaking of the hand movement of such personnel can be more frequent, the normal touch operation can be misrecognized as no operation intention. In this case, the first probability threshold can be appropriately lowered, such as from 0.4 to 0.3, to prevent interference to the normal touch operation.

[0091] For example, for the younger personnel, such as personnel younger than 12 years old. Since the children are lively and active, the first probability threshold can be appropriately increased, such as from 0.4 to 0.5, to prevent the children from mis-touching to interfere with driving.

[0092] For example, for the younger personnel, such as personnel younger than 12 years old, the key functions in the vehicle display screen closest to the personnel can be directly locked. For example, the seat adjustment function, the window control function and the child lock control function of the chair back screen in front of the child seat are locked.

[0093] The embodiments of the present disclosure adjust the probability threshold of the anti-mis-touch detection according to the age of the personnel in the cabin, so that users of different age groups can obtain similar anti-mis-touch protection effect.

[0094] In some embodiments of the present disclosure, optionally, the action feature information includes hand movement trajectory information, line of sight focus position information and sitting posture information; the driving feature information includes a jolt index; The operation probability is determined according to the action feature information and the driving feature information, including: determining the operation probability according to the hand movement trajectory information, the line of sight focus position information, the sitting posture information, the jolt index and a preset operation probability model.

[0095] In the embodiments of the present disclosure, the action feature information includes hand movement trajectory information, line of sight focus position information and sitting posture information. For example, the hand movement trajectory information of the personnel can be collected by a TOF camera. For example, the line of sight focus position information of the personnel can be collected by a DMS camera. For example, the sitting posture information of the personnel can be collected by a seat pressure sensor.

[0096] The driving feature information includes a jolt index. For example, the acceleration and angular velocity of the vehicle can be collected by a vehicle-mounted inertia detection unit, and the jolt index can be calculated by the acceleration variance and angular velocity variance.

[0097] An operation probability model is constructed as follows: ; Wherein, is the operation probability. Score the pointing direction of the hand motion trajectory information. For example, if the hand motion trajectory is always close to the target control, the pointing direction of the hand motion trajectory information is higher, and if the hand motion trajectory is random walk, the pointing direction of the hand motion trajectory information is lower.

[0098] Score the gaze focus position information. For example, if the gaze focus position is consistent with the position of the function control, the score is 1, and if the gaze focus position is not consistent with the position of the function control, the score is 0.

[0099] Score the reverse of the jolt index. For example, the higher the jolt index, the lower the score. The lower the jolt index, the higher the score.

[0100] Score the stability of the sitting posture information. For example, if the person's sitting posture is stable, the score is 1. If the person's sitting posture is shaking, the score is 0.3.

[0101] , , and are weight coefficients. For example, the above weight coefficients can be optimized online by a machine learning model. For example, the above weight coefficients can be determined by a pre-trained lightweight neural network model. The input of the lightweight neural network model is historical user operation data, including false touch samples and real operation samples. The output of the lightweight neural network model is the combination of the optimal weight coefficients. The above lightweight neural network model can be trained before the vehicle is shipped and deployed in the vehicle domain controller to support online fine-tuning.

[0102] The embodiments of the present disclosure can accurately identify the operation probability of the person in the cabin, and determine whether there is a false touch risk according to the identified operation probability. When the operation probability is low, the false touch risk is reduced by controlling the vehicle display screen to enter the locked state. When the operation probability is high, whether to run the function program of the function control in advance can be determined based on the jolt index of the vehicle, and the touch success rate is improved.

[0103] In some embodiments of the present disclosure, optionally, controlling the vehicle display screen to enter the locked state comprises: controlling the vehicle display screen to display a locked mask image, and controlling the vehicle display screen to enter the locked state; wherein the locked mask image covers the function control; After controlling the vehicle display screen to enter the locked state, the method further comprises: In the case of detecting the touch operation on the function control, display prompt information; wherein the prompt information is used to indicate that the function control is locked.

[0104] In the embodiments of the present disclosure, when the operation probability of the person is detected to be lower than the first probability threshold, the vehicle-mounted display screen is controlled to enter a lock screen state. In the lock screen state, the vehicle-mounted display screen automatically shields the touch operation on the key function control.

[0105] At this time, the vehicle-mounted display screen displays a mask image covering the key function control. Illustratively, the mask image is a virtual lock screen layer. For example, the mask image is a transparent or semi-transparent layer and covers the function control.

[0106] Illustratively, Figure 3 A lock screen state schematic diagram of a vehicle-mounted display screen provided by the embodiments of the present disclosure is shown in Figure 3 As shown, after entering the lock screen state, the vehicle-mounted display screen 30 displays a mask image 34 covering the function control 32 on the function control 32.

[0107] Illustratively, the mask image can be generated by a graphic rendering engine of an in-vehicle infotainment (IVI) and is displayed as an independent layer on the GUI (Graphical User Interface) framework of the vehicle-mounted display screen and is located at the front end of the touch event distribution queue. When a touch input is detected, the system first determines whether the touch input is located in the image display area of the mask image. If the coordinates of the touch input are located in the image display area of the mask image, the touch event is discarded and is not transmitted to the underlying application. At this time, the person can still visually see the function control in the original interface, but the touch input is intercepted and the interface prompts: “Hand movement is detected. Operation is temporarily locked”.

[0108] Illustratively, the person in the cabin can control the vehicle-mounted display screen to immediately exit the lock screen state and prevent the vehicle-mounted display screen from entering the lock screen state again within a certain preset time period through a specific function control, gesture operation, voice instruction or physical button. In this way, the interference to the normal touch operation of the person can be avoided.

[0109] The embodiments of the present disclosure can give a visual effect to the anti-mis-touch function, helping the user to quickly master whether the vehicle-mounted display screen has entered the lock screen state of the anti-mis-touch function.
