[0066] The technical solutions of the present application will be described in detail below with reference to the drawings. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0067] Figure 1is a flowchart of a vehicle-mounted screen 3D simulation seat adjustment interaction method provided by one or more embodiments of the present application.

[0068] As shown in Figure 1 , comprising the following steps:

[0069] Initialization configuration step S1: acquiring a 3D engine, and constructing a 3D virtual model corresponding to a physical seat of a vehicle according to the 3D engine;

[0070] Displaying the 3D virtual model on a user interaction interface;

[0071] Establishing a dynamic binding relationship between the 3D virtual model and a seat unit, determining a spatial state, and completing initial calibration according to the spatial state;

[0072] Interaction instruction receiving step S2: acquiring a touch operation of a user on a target adjustment component in the 3D virtual model, analyzing a type, a trajectory and target component information of the touch operation, and generating an interaction instruction; the target adjustment component includes a headrest, a backrest and a leg rest;

[0073] Adjustment control execution step S3: converting the interaction instruction into a seat motion control signal, sending the seat motion control signal to a seat motion control module, and driving the physical seat to perform a corresponding adjustment action;

[0074] Dual-mode feedback and state synchronization step S4: generating a highlighted semi-transparent guide rail projection through a visual feedback unit, and providing continuous click-type vibration through a tactile feedback unit;

[0075] Acquiring a real-time state of the physical seat, and driving the 3D virtual model to update synchronously.

[0076] Specifically, the 3D virtual model is used as an interaction intermediary to replace traditional physical buttons or single interface operations, and the dual-mode feedback and real-time state synchronization are combined to solve the problems of poor operation intuitiveness and untimely state perception in seat adjustment.

[0077] Specifically, the spatial state includes a spatial mapping relationship between the 3D virtual model and the physical seat.

[0078] The seat unit includes a seat driving motor, a sensor and a control unit.

[0079] Further, it includes:

[0080] The touch operation includes a long press and drag operation;

[0081] When the long press and drag of the user on the target adjustment component is detected, a continuous adjustment instruction is generated;

[0082] The adjustment parameter of the continuous adjustment instruction dynamically changes with the length or speed of the drag trajectory;

[0083] The adjustment parameter includes a movement distance or an angle of the target adjustment component.

[0084] Specifically, the intuitive linkage of the operation and the adjustment effect is realized, and the user interaction experience is improved.

[0085] Further, the method comprises the following steps.

[0086] The double-mode feedback and state synchronization step comprises that the highlight semi-transparent guide rail projection generated by the visual feedback unit is consistent with the preset movement direction of the target adjustment component, and the adjustment stroke scale is marked on the guide rail projection to display the distance between the current adjustment position and the limit position of the target adjustment component in real time.

[0087] Specifically, the adjustment stroke scale is added to the guide rail projection, and the scale needs to display the distance between the current adjustment position and the limit position in real time, so that the user can clearly know the remaining space of the seat adjustment, such as how many degrees the backrest can be reclined, and the seat limit protection triggered by excessive operation is avoided, and the interaction experience is further optimized.

[0088] Further, the method comprises the following steps.

[0089] The initialization configuration step comprises the following steps.

[0090] The actual size, joint connection structure and maximum adjustment freedom of the physical seat of the automobile are restored.

[0091] The 3D engine integrates a multi-degree-of-freedom pose prediction algorithm, which is used to predict the movement direction of the target adjustment component according to the initial touch position of the user; and a guide rail preview in the direction is pre-displayed on the 3D virtual model.

[0092] Specifically, by integrating the multi-degree-of-freedom pose prediction algorithm, the system can determine the possible movement direction of the component based on the initial touch position of the user, such as the headrest of the 3D model being touched by the finger, such as the up-down / forward-backward adjustment of the headrest, and the guide rail is pre-displayed, such as the transparent guide rail for up-down adjustment displayed beside the headrest to guide the user to operate, reduce the operation trial and error cost of the user, and improve the interaction efficiency, for example, the user does not need to repeatedly try, and can directly drag and adjust along the pre-displayed guide rail.

[0093] Further, the method comprises the following steps.

[0094] The adjustment control execution step comprises the following steps.

[0095] The adjustment range of the physical seat determined according to the initial calibration is excluded from the interaction instruction.

[0096] Specifically, by filtering invalid instructions in advance, the physical seat is prevented from performing actions beyond its own capabilities (such as hard pulling to the limit causing mechanical wear), while reducing invalid feedback caused by user errors, improving interaction reliability and seat device safety.

[0097] Further, comprising:

[0098] The dual-mode feedback and state synchronization step includes: the synchronization update of the 3D virtual model is delayed by no more than 100 ms; and the target adjusting component of the 3D virtual model is displayed with a position mark during synchronization, and the position mark has a deviation of less than 5 mm from the actual position of the corresponding component of the physical seat.

[0099] Specifically, it is ensured that the user can quickly see the state change of the virtual model after operation, avoiding operation perception disconnection caused by delay, and improving interaction fluency.

[0100] By requiring the target adjusting component (such as the headrest and the backrest) of the virtual model to display a position mark, and the deviation of the position mark from the actual position of the corresponding component of the physical seat being less than 5 mm, the precise mapping of the virtual model to the state of the physical seat is ensured by quantifying the accuracy standard, and the user's judgment error of the adjusting effect is reduced.

[0101] Further, comprising:

[0102] The dual-mode feedback and state synchronization step includes: the frequency of the continuous click-type vibration provided by the tactile feedback unit is positively correlated with the adjusting speed of the physical seat.

[0103] Specifically, the faster the adjusting speed of the physical seat, the higher the vibration frequency; when the physical seat reaches the adjusting limit position, the tactile feedback unit switches to a single strong vibration to prompt the adjusting boundary.

[0119] Figure 3 is a flowchart of a vehicle-mounted screen 3D simulation seat adjustment interaction method according to an embodiment of the present application.

[0120] As Figure 3 shown, the operation flow includes the following:

[0121] The user wakes up the system by double-clicking the armrest screen, and the screen displays a 3D overhead view of the vehicle interior, with the seat model highlighted in blue;

[0122] Click on the seat model to enter the adjustment interface, and the system automatically loads the current seat posture parameters, such as a backrest angle of 25° and a cushion height of 120mm, and labels them on the 3D model;

[0123] After selecting the seat movement function, a two-way sliding bar appears on the interface, such as a backrest angle of 0-180° and a cushion front and back of 0-200mm. When the user drags the sliding bar: the 3D model moves in real time and synchronously, with 60 frames refreshed per second;

[0124] The pressure sensor collects the cushion pressure distribution data and displays it in the form of a heat map in the lower right corner of the interface;

[0125] After confirming the adjustment parameters, the motion planner uses a trapezoidal velocity curve to plan the motor motion trajectory, and the drive motor executes the adjustment. The entire process takes ≤2.5 seconds.

[0126] In one embodiment, when the vehicle is in an autonomous driving scenario, the seat automatically adjusts to the relaxation / work mode.

[0127] After the vehicle enters autonomous driving mode, the system automatically triggers the intelligent adaptation mode, and the armrest screen displays the relaxation / work / rest three-mode options;

[0128] After the user selects the relaxation mode:

[0129] The millimeter wave radar scans the passenger's height and shoulder width, and generates a human body shape model combined with the seat pressure data;

[0130] The Tailor algorithm calculates the optimal posture: backrest angle 110°, leg support extension 50mm, and lateral support intensity adjusted to 60%;

[0131] The motion planner uses a fuzzy PID control strategy to convert the adjustment parameters into motor control signals, and the magnetorheological damper suppresses road vibrations in real time;

[0132] After the adjustment is complete, the armrest screen displays a comparison of the pressure distribution before and after the adjustment, and prompts that the optimal relaxation posture has been entered.

[0133] In another embodiment, the safety redundancy when the adjustment system is abnormal and the fault handling process are as follows:

[0134] When the motor is stuck and the current exceeds 150% of the rated value, the system immediately cuts off the power supply of the motor, and the handrail screen displays a red fault code E03-motor overload;

[0135] The buzzer emits intermittent alarms at a frequency of 2Hz, and a fault handling guide pops up: please try to manually adjust the emergency lever and contact the after-sales code E03;

[0136] If the sensor detects that the passenger's limbs are in a dangerous area (such as hands clamped in the seat gap) during adjustment, the system triggers an emergency stop, and the 3D interface highlights the dangerous area;

[0137] After troubleshooting, the system performs self-checking and restores the adjustment function after confirming normality.
