It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

The terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process.

The terminal 102 is used to create a virtual user role and a virtual driving scene according to the data stored in the server 104, and establish a vehicle simulation model based on the virtual driving scene. In the virtual driving scene, the user's driving state is simulated by the virtual user role, and the vehicle's motion state is simulated by the vehicle simulation model, and the vehicle charm point is designed according to the simulation results. The terminal 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices.

[0044] In an exemplary embodiment, as shown in FIG2 , a vehicle charm point design method is provided, and the method is applied to the terminal 102 in FIG1 as an example for description, including the following steps 202 to 206. Among them:

[0045] S202: Creating a virtual user role and a virtual driving scene.

[0046] Optionally, by creating a virtual user character that covers details such as appearance, body shape, and behavioral habits, and placing it in a virtual driving scenario, the user's behavior in various driving situations can be simulated. During this simulation process, the system can collect a large amount of data about how the user operates the vehicle (such as the frequency and timing of acceleration, braking, steering, etc.), how to interact with the vehicle's internal facilities (such as using the center console, adjusting the seat, etc.), and visual focus in different scenarios. For example, when the virtual user character is parameterized and customized based on real user data, a large-scale simulation analysis can be performed for the target user group. By analyzing the simulated behavior data of a large number of virtual user characters in different scenarios, the common needs and behavior patterns of the target user group can be discovered.

[0047] Optionally, when creating virtual driving scenarios (such as urban roads, country roads, bad weather, etc.), a parametric construction method is adopted, that is, various elements in the scene (such as the length, width, curvature of the road, the intensity of weather conditions, etc.) are controlled by adjustable parameters. For example, when creating an urban road scene, the traffic volume of the road, the time setting of traffic signals, the layout of buildings, etc. can all be represented by parameters. When the scene needs to be adjusted to meet different design requirements, only the corresponding parameter values ​​need to be modified. For example, to simulate the needs of different markets (such as densely populated large cities and small and medium-sized cities), this can be achieved by adjusting parameters such as traffic volume and traffic signal rules in the urban road scene. This parametric construction method makes the scene highly flexible and can quickly respond to different design requirements.

[0048] S204: Establishing a vehicle simulation model based on the virtual driving scenario.

[0049] Optionally, based on the principles of vehicle dynamics, a vehicle simulation model is established by considering factors such as the vehicle's mass, inertia, tire characteristics, suspension system, and power system. For example, the acceleration performance of a vehicle depends on the engine power, the efficiency of the transmission system, and the total mass of the vehicle; the steering performance of a vehicle is closely related to the lateral force of the tires, the geometric structure of the suspension, and the like. These physical relationships are described by precise mathematical models, so that the vehicle simulation model can accurately simulate the motion state of the vehicle under different driving operations. Afterwards, the various subsystems of the vehicle (such as power, braking, steering, etc.) are integrated into a unified model and adjusted according to the parameters of the actual vehicle. For example, the engine torque curve of different models of vehicles, the braking force distribution of the braking system, and other parameters are different. These accurate parameters are input into the vehicle simulation model to ensure that the model can truly reflect the actual performance of the vehicle.

[0050] S206: In the virtual driving scene, the user's driving state is simulated by the virtual user character, and the vehicle's motion state is simulated by the vehicle simulation model, and the vehicle's charm points are designed according to the simulation results.

[0051] Optionally, in a virtual driving scenario, an interactive simulation is performed between the virtual user character and the vehicle simulation model. The driving operation of the virtual user character (such as stepping on the accelerator, braking, turning the steering wheel, etc.) acts as input to the vehicle simulation model, and the vehicle simulation model calculates the vehicle's motion state (such as speed, acceleration, driving trajectory, etc.) based on its own dynamic model and feeds it back to the virtual user character as output. This human-computer interaction simulation can accurately reflect the dynamic relationship between the driver and the vehicle. According to the experience of the virtual user character and the performance of the vehicle during the simulation, the potential advantages (charming points) of the vehicle are found and designed. For example, if the simulation results show that in a specific driving scenario, a certain handling performance of the vehicle (such as cornering stability) has received good feedback from the virtual user character, then this feature can be further strengthened in the actual design of the vehicle; or if it is found that a certain function (such as intelligent driving assistance function) improves the driving comfort and safety of the virtual user character in the simulation, this function can be optimized and promoted in the actual design.

[0052] In the above-mentioned vehicle charm point design method, by creating a virtual user role and a virtual driving scene, and establishing a vehicle simulation model based on the virtual driving scene, in the virtual driving scene, the user's driving state is simulated by the virtual user role, and the vehicle's motion state is simulated by the vehicle simulation model, and the vehicle charm point is designed according to the simulation results, so that different vehicle design schemes can be quickly tested and compared, and the virtual driving simulation is re-performed to observe the impact of the simulation results on the vehicle charm point, so that the best design scheme can be found in a shorter time, thereby improving the design efficiency. In addition, since the virtual user role can simulate the driving behavior and experience of different types of users, the vehicle charm point design can be better carried out from the user's perspective to meet the personalized needs of users.

[0053] In an exemplary embodiment, the steps of creating a virtual user character and a virtual driving scene include: establishing a virtual object through 3D software; obtaining user data, updating the virtual object according to the user data, and obtaining a virtual user character; the user data includes a user image, body shape data, and behavior data; obtaining environmental data, the environmental data includes road types, weather conditions, and light and shadow conditions; and establishing virtual driving scenes under different road types, different weather conditions, and different light and shadow conditions according to the environmental data.

[0054] Optionally, a virtual object with a basic human body shape structure can be constructed through 3D modeling technology. This virtual object is an initial, general model that contains the basic geometric shapes of the human body, such as the head, torso, limbs and other parts. When mapping user data to a virtual object, it mainly includes three aspects: appearance, body shape and behavior. Among them, the user image can provide appearance information such as facial features. Through image processing technology, such as feature point recognition, texture mapping, etc., the facial features in the user image are extracted and mapped to the head model of the virtual object, so that the virtual object has a facial appearance similar to that of the user. Body shape data is used to adjust the body proportion and size of the virtual object. According to the input body shape data such as height, weight, body proportion, etc., the torso, limbs and other parts of the virtual object are scaled, deformed, etc., so that the body shape of the virtual object matches the user. Behavior data reflects the user's dynamic characteristics such as action habits and reaction speed. Using the principle of kinematics, the behavior data is converted into the action mode of the virtual object.

[0055] Optionally, the road type data can be obtained from a geographic information system (GIS), including the topological structure, curvature, slope and other information of different types of roads such as urban roads, highways, and rural roads. Weather condition data can be obtained from the database of the meteorological department or the sensor network, such as meteorological elements such as temperature, humidity, precipitation, and wind speed. Light and shadow condition data can be calculated by light sensors or sunshine models based on time and geographic location, including the intensity, direction, and shadow distribution of sunlight. According to different road type data, the corresponding road model is constructed in the 3D scene. For example, urban roads need to construct complex scenes including elements such as intersections, traffic signs, and buildings; highways pay more attention to the construction of facilities such as the straightness of the road, isolation belts, and service areas. For weather condition data, precipitation (rain, snow, etc.) effects are simulated through technologies such as particle systems, and the fluttering effect of objects in the wind is simulated according to wind speed data. Using the light and shadow model, the lighting effects in the scene are set according to the light and shadow condition data. For example, the angle of sunlight will affect the direction and length of the shadow of the object, and different weather conditions (such as cloudy and sunny days) will affect the overall light intensity and color.

[0056] In this embodiment, by creating a virtual user role, the vehicle design can be made to better meet the needs of the target user group. In the virtual driving scenario, various complex user behaviors and environmental conditions can be simulated, different vehicle design schemes can be tested, and potential safety hazards in the vehicle design can be discovered in advance, thereby improving the safety of the vehicle.

[0057] In an exemplary embodiment, the steps of establishing a vehicle simulation model based on a virtual driving scene include: obtaining design data of the vehicle and establishing an initial model based on the design data; the design data includes vehicle exterior design, interior design and lighting design; rendering the initial model to the virtual driving scene; obtaining feedback triggered by the user through a VR device, adjusting the design parameters of the initial model based on the feedback, and obtaining a vehicle simulation model.

[0058] Optionally, the vehicle appearance design data includes information such as body shape, size, line direction, color, etc. When establishing the initial model, computer-aided design (CAD) technology is used to convert these appearance design data into a three-dimensional geometric model. The interior design data covers information such as seat layout, instrument panel design, and the position and shape of control components (such as steering wheel, gear lever, etc.). When incorporating these data into the initial model, ergonomic principles should be considered. For example, the height, angle and shape of the seat should meet the requirements of a comfortable sitting posture for the human body, and the layout of the instrument panel should be convenient for the driver to view and operate. The lighting design data includes information such as the layout, illumination angle and light intensity of the headlights, taillights, and interior lighting. In the initial model, the position and direction of the lights are set according to optical principles. For example, the illumination angle of the headlights should meet the road lighting standards, and the light distribution under different lighting modes (such as low beam and high beam) should be taken into account.

[0059] Optionally, the established initial model is converted into an image that can be displayed in the virtual driving scene. During the rendering process, the lighting effect, color, texture and other properties of the model surface are calculated using a graphics rendering algorithm (such as a ray tracing algorithm, a rasterization algorithm, etc.). The initial vehicle model is illuminated and rendered according to the ambient light (such as sunlight, street lights, etc.) and light and shadow conditions (such as shadows, reflections, etc.) in the virtual driving scene, and then the rendered initial vehicle model is placed in the virtual driving scene. By adjusting the posture of the vehicle model in the virtual driving scene (such as tilt angle, height, etc.) to match it with the terrain in the scene (such as slope, potholes, etc.), the seamless integration of the vehicle and the virtual driving scene is achieved.

[0060] Optionally, users can interact with the initial vehicle model in a virtual driving scene through VR devices. For example, users can use VR handles to operate vehicle switches, adjust seat positions, etc., and these operations will be recorded as feedback. Afterwards, the design parameters of the initial model are adjusted based on user feedback to make it more in line with user needs.

[0061] In this embodiment, by obtaining the design data of the vehicle, establishing an initial model according to the design data, rendering the initial model to a virtual driving scene, obtaining feedback from the user triggered by a VR device, adjusting the design parameters of the initial model according to the feedback, and obtaining a vehicle simulation model, the vehicle design can more accurately meet user needs, and when the user participates in the construction of the vehicle simulation model through the VR device, the user can intuitively feel the design features of the vehicle.

[0062] In an exemplary embodiment, in a virtual driving scenario, the steps of simulating the user's driving state through a virtual user character and simulating the vehicle's motion state through a vehicle simulation model include: simulating the user's driving actions, emotional reactions and physiological reactions through the virtual user character; driving actions include turning the steering wheel and stepping on the pedals, emotional reactions include facial expressions and voice emotions, and physiological reactions include heart rate and skin electrical reactions; simulating the vehicle's motion state and sound state in different driving scenarios through the vehicle simulation model, and responding to the virtual user character's driving actions through the vehicle simulation model.

[0063] Optionally, in the virtual user character, by establishing a motion model of human joints, these driving actions are simulated according to the action data of the real driver or the preset standard action mode. In addition, the driving action of the virtual user character is associated with the control logic of the vehicle. For example, the turning angle of the steering wheel will be converted into the vehicle steering instruction, and the pedal depression depth will be converted into the vehicle acceleration or deceleration instruction. Afterwards, according to the emotional response (such as satisfaction or dissatisfaction with the driving scene), this model is used to drive the movement of facial muscles to simulate the corresponding facial expression. And, by analyzing the relationship between voice features and emotions, a voice with corresponding emotions is generated according to the emotional state of the virtual user character. When simulating physiological reactions, according to physiological principles, different driving scenarios (such as dangerous road conditions, comfortable road conditions) and driving behaviors (such as high-speed driving, fatigue driving) will cause changes in the physiological state of the human body. For example, in a dangerous driving scenario, the human body will have an accelerated heart rate and an increased skin conductivity. By constructing a mathematical model, the corresponding heart rate and skin electrical response values ​​are calculated according to the stimulus factors in the virtual driving scene (such as sudden obstacles) and the driving behavior of the virtual user character.

[0064] Optionally, the vehicle's motion state (such as speed, acceleration, driving trajectory, etc.) is simulated based on the principle of vehicle dynamics. Considering factors such as the vehicle's mass, inertia, friction between the tire and the ground, and air resistance, the vehicle's motion state under different driving actions is calculated by establishing the vehicle's dynamic equation. For example, when the virtual user character steps on the accelerator pedal, the vehicle's acceleration is calculated based on the engine's power output characteristics, the efficiency of the transmission system, and the various resistances suffered by the vehicle, and then the vehicle's speed and driving trajectory are updated. Different driving scenarios (such as urban roads, mountain roads, highways, etc.) have different road conditions (such as slope, curve radius, traffic flow, etc.). When simulating the vehicle's motion state, it is necessary to consider the impact of these scenario factors on the vehicle. For example, on mountain roads, the vehicle's climbing ability and braking performance when going downhill need to be adjusted according to the road slope; on urban roads, vehicles need to start and stop frequently, and the impact of traffic signals and other vehicles must be considered.

[0065] Among them, the sound state of the vehicle (such as engine roar, tire friction sound, brake sound, etc.) is simulated based on acoustic principles. Different vehicle components will produce sounds of specific frequencies and loudness during movement. For example, the engine speed is related to the frequency of the sound emitted. The higher the speed, the higher the sound frequency; the friction sound between the tire and the ground depends on factors such as the material and pattern of the tire and the speed of the vehicle. By establishing a sound model, the corresponding sound parameters are calculated according to the vehicle's movement state (such as speed, engine speed, etc.), thereby simulating the sound state of the vehicle.

[0066] In this embodiment, the user's driving actions, emotional reactions and physiological reactions are simulated by a virtual user character, the movement state and sound state of the vehicle in different driving scenarios are simulated by a vehicle simulation model, and the vehicle simulation model responds to the driving actions of the virtual user character. This can accurately simulate the interaction state between the user and the vehicle, make the virtual driving scene more realistic, and allow the user to more intuitively feel the various situations in the driving process.

[0067] In an exemplary embodiment, the steps of designing the vehicle's charm points based on the simulation results include: determining user needs based on the user's emotional and physiological reactions; determining performance requirements based on the engine sound and environmental noise generated by the vehicle simulation model during the simulation process; determining the design parameters of the vehicle based on the user needs and performance requirements, and generating a vehicle charm point design scheme based on the design parameters to achieve the vehicle charm point design.

[0068] Optionally, user needs are determined through the user's emotional and physiological reactions during the simulation. For example, in a virtual driving scenario, if the user shows a pleasant emotional response, it may mean that they are relatively satisfied with certain aspects of the vehicle (such as driving comfort, vehicle appearance, etc.). This positive emotion can be interpreted as a demand tendency for these aspects, that is, the user hopes to retain or strengthen these factors that bring pleasure in the actual vehicle.

[0069] Optionally, the performance requirements are determined through the engine sound and environmental noise generated by the vehicle simulation model during the simulation process. For example, a low and steady engine roar may indicate that the engine has good torque output and a stable operating state, which reflects the user's demand for power performance. If the engine sound becomes sharp or noisy at high speed, it may indicate that the engine's performance is unstable under high load, and the engine design needs to be optimized to improve its performance at high speed to meet the user's demand for power performance.

[0070] Furthermore, according to user needs (from emotional and physiological reactions) and performance needs (from engine sound and environmental noise), these needs are converted into specific vehicle design parameters. For example, if the user demand is to improve driving comfort and the performance demand is to reduce environmental noise, these needs can be converted into parameters such as the selection of sound insulation materials and body structure design of the vehicle. After that, a vehicle charm point design scheme is generated based on these parameters. For example, after determining the high-performance design parameters of the engine and the user's demand for driving pleasure, the vehicle's exterior design can be combined with the power performance to create a sporty exterior line that matches the high-performance engine and forms a charm point of the vehicle. At the same time, according to the user's demand for comfort and vehicle interior space, combined with design parameters such as sound insulation and interior decoration, a spacious, comfortable and quiet interior environment can be designed, which also becomes a charm point of the vehicle. By integrating various design parameters, a holistic and uniquely attractive vehicle charm point design scheme is formed.

[0071] In this embodiment, user needs are determined based on the user's emotional and physiological reactions, performance requirements are determined based on the engine sound and environmental noise generated by the vehicle simulation model during the simulation process, vehicle design parameters are determined based on user needs and performance requirements, and a vehicle charm point design plan is generated based on the design parameters to achieve vehicle charm point design. This can better design vehicle charm points from the user's perspective and meet the user's personalized needs.

[0072] In an exemplary embodiment, the method further includes: in the process of simulating the user's driving state through the virtual user character and simulating the vehicle's motion state through the vehicle simulation model, displaying the driving perspective of the virtual user character through a virtual driving scene; in the process of the user accessing the virtual driving scene through a VR device, obtaining the user's optimization opinions on the driving perspective, and generating an optimization design plan based on the optimization opinions.

[0073] Optionally, the virtual driving perspective interacts with the virtual driving scene to present a realistic driving visual effect. When the virtual user character performs driving actions (such as turning the vehicle, accelerating, etc.) in the vehicle simulation model, the driving perspective will be adjusted accordingly according to the vehicle's motion state and elements in the scene (such as road curves, surrounding buildings, etc.). For example, when the vehicle turns, the driving perspective will shift to one side according to the turning direction and speed, and at the same time, the surrounding scene elements will move and deform accordingly in the perspective according to the perspective principle.

[0074] Optionally, when a user accesses a virtual driving scene through a VR device, he or she can personally experience the virtual driving process from a first-person perspective. The optimization opinions generated by the user for the driving perspective are based on their needs in real driving or expected driving experience. For example, the user may find that the field of view of the rearview mirror in the virtual driving perspective is not clear enough or the range is not large enough. Generating an optimization design scheme based on the user's optimization opinions is based on the comprehensive application of the principles of vehicle design and virtual driving scene construction. By analyzing the commonalities and key issues in the user's optimization opinions, combined with the technical requirements of vehicle design and virtual scene construction, a specific optimization design scheme is formulated, such as adjusting the design parameters of the instrument panel, changing the virtual model of the rearview mirror, or adjusting its display method in the virtual scene.

[0075] In this embodiment, by simulating the user's driving state through a virtual user character and simulating the vehicle's motion state through a vehicle simulation model, the driving perspective of the virtual user character is displayed through a virtual driving scene. When the user accesses the virtual driving scene through a VR device, the user's optimization opinions on the driving perspective are obtained, and an optimization design plan is generated based on the optimization opinions. This can provide the user with a more personalized driving experience, allow the user to directly interact with the virtual driving scene, and meet the user's various needs.

[0076] In an exemplary embodiment, as shown in FIG3 , a vehicle charm point design method is provided, the method comprising the following steps:

[0082] In this embodiment, by creating a virtual user role and a virtual driving scene, and establishing a vehicle simulation model based on the virtual driving scene, in the virtual driving scene, the user's driving state is simulated by the virtual user role, and the vehicle's motion state is simulated by the vehicle simulation model, and the vehicle's charm point design is performed according to the simulation results, so that different vehicle design schemes can be quickly tested and compared, and the virtual driving simulation is re-performed to observe the impact of the simulation results on the vehicle's charm point, and then the best design scheme can be found in a shorter time, thereby improving the design efficiency.
