[0002] With the advancement of technology, new models in the automotive industry have mushroomed. With the increase in options, customers are paying more and more attention to the comfort of the vehicle in addition to traditional safety and functional requirements. Since the frequency of getting on and off the vehicle is very high during daily use, vehicle manufacturers have included the convenience of getting on and off the vehicle as a key indicator in the early design stage. In addition to the above comfort requirements, vehicle manufacturers are also paying more and more attention to market segments and developing special models for specific usage scenarios. The way of getting on and off the vehicle is also different from that of traditional models, which also requires in-depth research on the convenience of getting on and off the vehicle in engineering.

[0003] At present, most of the designs for the convenience of getting on and off passenger cars in China are developed by collecting statistics on the door opening dimensions and accumulating experience.

If there is a conflict between important dimensions and other structures of the vehicle, how to make a choice; how to evaluate the comfort of getting on and off unconventional models; there is no unified standard. In addition, the human body has many joints, and each joint has its own degree of freedom of movement, which makes it even more difficult to evaluate the comfort of getting on and off the vehicle.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0054] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0055] This application is applied to the scenario of rectifying vehicle models. The specific scenario is to set up a model to simulate the scenes of customers getting on and off the vehicle, and analyze the comfort of passengers through the dynamic scenes of getting on and off the vehicle, and then adjust the vehicle model to improve customer comfort.

[0056] With the advancement of technology, new models in the automotive industry have also sprung up like mushrooms after rain. With the increase in options, customers are paying more and more attention to the comfort of the whole vehicle in addition to the traditional safety and functional requirements. Due to the high frequency of getting on and off the vehicle in daily use, vehicle manufacturers have included the convenience of getting on and off the vehicle as a key indicator in the early stage of design. In addition to the above comfort requirements, vehicle manufacturers are also paying more and more attention to the market segmentation, developing special models for specific usage scenarios, and the way of getting on and off the vehicle is also different from traditional models, which also requires in-depth research on the convenience of getting on and off the vehicle in engineering. At present, most of the domestic designs for the convenience of getting on and off passenger cars are developed by statistically analyzing the door opening dimensions and accumulating experience values. Although the general direction will not go wrong, it is difficult to improve the comfort of different groups of people when using it. If there is a contradiction between important dimensions and other structures of the whole vehicle, how to make a choice; how to evaluate the comfort of getting on and off unconventional models; there is no unified standard. In addition, the human body has many joints, and each joint has its own freedom of movement, which makes it even more difficult to evaluate the comfort of getting on and off the vehicle.

[0057] To this end, this application sets up a three-dimensional human body model by combining the body size information of a standard passenger group; uses the three-dimensional human body model to simulate the process of passengers getting on and off the bus according to preset boarding and alighting parameters, and collects dynamic images of getting on and off the bus, wherein the preset boarding and alighting parameters include all the actions of getting on and off the bus; analyzes the parts of the vehicle model that affect the comfort of passengers in the dynamic images of getting on and off the bus, and improves the parts of the vehicle model. In the simulation research of new vehicles, the whole vehicle model is continuously improved according to user comfort feedback and animation analysis by simulating the process of passengers getting on and off the bus, until the vehicle model meets the preset requirements, and a vehicle model that meets customer comfort is obtained, shortening the cycle of vehicle development.

[0058] In the embodiment of the present application, the executing entity may be a whole vehicle model comfort improvement device in a whole vehicle model comfort improvement system. In actual applications, the whole vehicle model comfort improvement device may be electronic devices such as terminal devices and servers, which are not limited here.

[0059] Combine the following Figure 1The method for improving the comfort of the whole vehicle model in an embodiment of the present application is described in detail.

[0060] Please see Figure 1 , Figure 1 A flowchart of a method for improving the comfort of a vehicle model provided in an embodiment of the present application, such as Figure 1 The methods shown to improve the comfort of the whole vehicle model include:

[0061] Step 110: Setting a three-dimensional human body model based on the body size information of a standard passenger group.

[0062] The standard passenger group can be selected according to the needs, for example, the average body size in the crowd or the approximate body size of most people in the crowd. Body size information may include height, sitting height, waist circumference, shoulder width and other dimensions.

[0063] In some embodiments of the present application, a three-dimensional human body model is set in combination with the body size information of a standard passenger group, including: selecting the sizes of various parts of the human body that respectively conform to 95%, 50% and 5% of the standard male sizes and 5% of the standard female sizes as the body size information; and setting the three-dimensional human body model according to the body size information.

[0064] In the above embodiment of the present application, the standard male and female body shapes with preset proportions are used as body size information to set the three-dimensional human body model, so that the three-dimensional human body model can meet the physical needs of most passengers.

[0065] Among them, each part may include any part of the human body. Selecting the size of each part of the human body that meets the 95%, 50% and 5% standard male size and the 5% standard female size as the body size information is only one implementation method of the present application, and the specific proportion selection size information can also be set according to user needs. In addition, setting the human body three-dimensional model can also set human body environment parameters, including posture, coordinate system, joint range of motion statistical ratio and a certain point offset and other parameters.

[0066] Optionally, when setting up the three-dimensional model of the human body, it is also necessary to analyze the sudden change values ​​of the forces on various parts of the human body and step through the constraint geometry model settings until the forces on various parts of the human body are close to the actual situation. Calculate the weight of the wheelchair plus the person and the weight of the human body, and preliminarily assess whether the entire wheelchair boarding process is within the target value range based on the weight ratio of each part. Divide the boarding auxiliary board into sections, adjust the slope angle, adjust the threshold height, and repeat the above steps until the forces on the human body during the wheelchair boarding process are within the target value range. The target range can be set as needed.

[0067] Step 120: According to the preset boarding and alighting parameters, a three-dimensional human body model is used to simulate the process of passengers boarding and alighting, and dynamic images of the passengers boarding and alighting are collected.

[0068] Among them, the preset parameters for getting on and off the vehicle include all the actions of getting on and off the vehicle, the size of the vehicle model, the decomposition steps of all the actions of getting on and off the vehicle, and the range information of the action activities. The passenger can be a wheelchair user, and the wheelchair can perform turning activities in the vehicle.

[0069] In some embodiments of the present application, according to preset boarding and getting on parameters, a three-dimensional human body model is used to simulate the process of passengers getting on and off the bus, and dynamic images of getting on and off the bus are captured, including: controlling the three-dimensional human body model to simulate passengers getting on and off the bus according to the boarding and getting on parameters; capturing the before and after states of passengers getting on and off the bus through a camera; inserting a preset number of intermediate passenger postures in the before and after states of passengers getting on and off the bus to obtain dynamic images of passengers getting on and off the bus.

[0070] In the above process, the present application can use a three-dimensional human body model to simulate passengers getting on and off the vehicle, and appropriately add intermediate postures to obtain a more complete getting on and off the vehicle animation, thereby providing a basis for the final analysis of the comfort of getting on and off the vehicle.

[0071] Among them, the state before and after getting on and off the bus may include one or more images collected before and after the passenger gets on and off the bus. The preset number can be set according to demand. The intermediate passenger posture includes multiple passenger images taken between before and after getting on and off the bus.

[0072] Step 130: Analyze the vehicle model parts that affect the passenger comfort in the dynamic picture of getting on and off the vehicle, and improve the vehicle model parts.

[0073] In some embodiments of the present application, when the passenger is a wheelchair user, the parts of the vehicle model that affect the passenger comfort in the dynamic screen of getting on and off the vehicle are analyzed, and the parts of the vehicle model are improved, including: analyzing the contact points between various parts of the passenger and the vehicle model in the dynamic screen of getting on and off the vehicle and the force conditions of the contact points; modifying the contact points and force conditions to be preset contact points and within a preset force range; adjusting the angle of the boarding auxiliary plate and the threshold height according to the passenger's range of activities when getting on the vehicle.

[0074] In the above process, the present application can analyze the animation to obtain the body movement range of the accompanying person of the wheelchair passenger getting on and off the vehicle, the movement angle of each joint, and the joint load, and compare them with the comfort target range, and then adjust the vehicle model parameters, namely the threshold height from the ground, the length of the boarding auxiliary board, the slope of the boarding auxiliary board, and the size of the door opening, to improve passenger comfort.

[0075] During the analysis, the contact points and contact force conditions can be set through simulation. The specific contact points and force conditions can be determined based on the actual contact points and forces touched by customers getting on and off the vehicle. In addition, model parts such as the threshold height from the ground, the length of the boarding auxiliary board, the slope of the boarding auxiliary board, the size of the door opening, the steering width of the wheelchair, the boarding passage for accompanying persons, and the interior boundary can be improved according to the contact points and force conditions. The above model parts can be analyzed using common vehicle models first.

[0076] Optionally, analyze the parts of the vehicle model that affect the passenger comfort in the dynamic screen of getting on and off the vehicle, and improve the parts of the vehicle model, including: analyzing the contact points between various parts of the passenger and the vehicle model in the dynamic screen of getting on and off the vehicle and the force conditions of the contact points; modifying the contact points and force conditions to be preset contact points and within a preset force range, including: establishing a geometric model of the position of the human body's feet and hands at each step, defining the contact points between various parts of the passenger and the vehicle model, constraining the human body's hands and feet and the model, simulating the animation of getting on and off the vehicle, analyzing the human body's activity space and the activity angles and weight of each joint; modifying the entire vehicle model, optimizing the contact point position, and then the activity angles and weight of each joint of the human body, until the angles and weight of each joint of the human body are within the preset force range.

[0077] Optionally, according to the analysis of the vehicle model parts that affect the passenger comfort in the dynamic screen of getting on and off the vehicle, and the improvement of the vehicle model parts and the range of activities of the passengers getting on the vehicle, the angle of the boarding assist plate and the threshold height are adjusted, including: according to the quantified vehicle model parameters, namely, the threshold height from the ground, the length of the boarding assist plate, the slope of the boarding assist plate, and the size of the door opening.

[0078] In some embodiments of the present application, vehicle model parts that affect passenger comfort in the dynamic picture of getting on and off the vehicle are analyzed, and improvements are made to the vehicle model parts, including: adding multiple action postures of multiple passengers in the dynamic picture of getting on and off the vehicle to obtain a modified animation; analyzing the range of passengers' getting on and off the vehicle in the modified animation; and modifying relevant parameters of the door opening according to the range of passengers' getting on and off the vehicle.

[0079] In the above process, the present application can add multiple movements and postures of multiple passengers in the dynamic picture of getting on and off the vehicle, fully simulating the whole process of passengers getting on and off the vehicle, and then accurately analyzing the passengers' activity range to the vehicle dashboard and other interior boundaries, thereby improving customer comfort.

[0080] Among them, each action posture can be an action image, and each action posture can be obtained by inserting custom settings. Relevant parameters include length, width, shape and other parameters. The wheelchair can be associated with the passenger, and the passenger's initial position, process position, and final position in the car can be set. The camera is used to record the human body posture at each position; the intermediate analysis posture is inserted between each posture to obtain the human body activity envelope and optimize the dashboard and other interior boundaries of the vehicle. The modified animation includes the modified animation and motion envelope.

[0081] In some embodiments of the present application, vehicle model parts that affect passenger comfort in dynamic pictures of getting on and off the vehicle are analyzed, and improvements are made to the vehicle model parts, including: analyzing a second vehicle model part that affects the comfort of passengers and their companions in dynamic pictures of getting on and off the vehicle, and improving the second vehicle model part.

[0082] In the above process, the present application can analyze the comfort of passengers getting on and off the vehicle through animations such as the wheelchair getting on the vehicle, the wheelchair being fixed, and the passenger getting on the vehicle, and then adjust the entire vehicle model to improve the overall comfort of getting on and off the vehicle.

[0083] Among them, the second vehicle model part is a model used for special personnel to get on and off the vehicle, for example, disabled people in wheelchairs.

[0084] In some embodiments of the present application, after analyzing the vehicle model parts that affect the passenger comfort in the dynamic picture of getting on and off the vehicle and improving the vehicle model parts, Figure 1 The method shown also includes: counting the comfort of each body part of the passengers and their companions during boarding and alighting; counting the comfort scores of each body part; and modifying the vehicle model based on the scores and the analysis results of professionals.

[0085] In the above process, the present application can improve the vehicle comfort to the greatest extent by analyzing the comfort scores of body parts of passengers and their companions during boarding and getting on the vehicle and combining the modification suggestions and rectification model given by professionals.

[0086] The comfort level can be evaluated based on the comfort level given by passengers and accompanying personnel. The comfort level can include multiple levels such as "comfortable", "average" and "uncomfortable". Different levels can correspond to different scores, or the customer can directly score after giving a comfort level evaluation.

[0087] In the above Figure 1In the process shown, the present application sets a three-dimensional human body model by combining the body size information of the standard passenger group; uses the three-dimensional human body model to simulate the process of passengers getting on and off the vehicle according to the preset boarding and getting off parameters, and collects dynamic pictures of getting on and off the vehicle, wherein the preset boarding and getting off parameters include all the actions of getting on and off the vehicle; analyzes the parts of the vehicle model that affect the comfort of passengers in the dynamic pictures of getting on and off the vehicle, and improves the parts of the vehicle model. In the simulation research of new vehicles, by decomposing the process of passengers getting on and off the vehicle, simulating the boarding and getting off actions and generating boarding and getting off animations, boarding and getting off joint angles, and joint loads, combined with user comfort feedback, the whole vehicle model is continuously rectified until the vehicle model meets the preset requirements, and a vehicle model that meets customer comfort is obtained, shortening the cycle of vehicle development.
