[0020] Figure 1 Schematic diagram of a test drive simulation system according to an embodiment of the present invention. Figure 1 In the illustrated embodiment, the test drive simulation system includes a contour fitting subsystem 11, a multimodal enhancement subsystem 12, a brain-computer interface subsystem 13, a management subsystem 14, an API (Application Programming Interface) interface 15, a contour fitting device 16, a multimodal device 17 and a brain-computer interface device 18.

[0021] The contour fitting subsystem 11 and the contour fitting device 16 are used as fitting systems, which interact with each other through wireless communication equipment to jointly realize the shape recognition and modeling of the vehicle and complete the fitting of the vehicle body contour. The contour fitting device 16 includes a robot arm 161, an existing vehicle body frame 162, a human-computer interaction facility 163 and a first wireless communication device 164.

[0022] The multimodal enhancement subsystem 12 and the multimodal device 17 are multimodal simulation systems that interact with each other through wireless communication devices. After fitting the vehicle contour, they jointly provide users with a more immersive augmented reality experience by integrating multiple perception modes such as vision, hearing, and touch. The multimodal device 17 includes a multimodal wearable device 171, an environment simulation device 172, and a second wireless communication device 173.

[0023] The brain-computer interface subsystem 13 and the brain-computer interface device 18 serve as a brain-computer signal acquisition system, and exchange data through wireless communication devices to jointly achieve the acquisition of the user's brain-computer signals during the multimodal simulation process. The brain-computer interface device 18 includes an EEG acquisition device 181, a signal processing device 182, and a third wireless communication device 183.

[0024] The management subsystem 14 is responsible for data interaction and data processing between the contour fitting subsystem 11 , the multimodal enhancement subsystem 12 and the brain-computer interface subsystem 13 and the contour fitting device 16 , the multimodal device 17 and the brain-computer interface device 18 .

[0025] The API interface 15 is used to call a database including comprehensive vehicle parameters and key detection points, obtain the vehicle design parameters or actual vehicle parameters and key detection points corresponding to the target vehicle model from the database, and provide them to the profile fitting subsystem 11 and the multimodal enhancement subsystem 12 for profile fitting and multimodal simulation respectively. The API interface 15 is also used to feed back the emotional state information and related simulation behavior information of each key detection point of the brain-computer interface subsystem 13 to the vehicle design or production link, to help it accurately understand the user's real experience of vehicle design and use.

[0026] Among them, the contour fitting subsystem 11, the multimodal enhancement subsystem 12 and the brain-computer interface subsystem 13 are respectively connected to the management subsystem 14. The contour fitting device 16, the multimodal device 17 and the brain-computer interface device 18 are respectively connected to the management subsystem 14. The API interface 15 is a data interface of the contour fitting subsystem 11, the multimodal enhancement subsystem 12 and the brain-computer interface subsystem 13, which can obtain data from a server or other services, or send data to a server or other services.

[0027] The profile fitting subsystem 11 first obtains the vehicle model information selected by the user through the management subsystem 14. Subsequently, the profile fitting subsystem 11 retrieves the automobile design parameters corresponding to the non-mass-produced vehicle model or the automobile actual parameters corresponding to the mass-produced vehicle model from the database including vehicle comprehensive parameters and key detection points using the API interface 15. The management subsystem 14 calculates the difference between the automobile design parameters or the automobile actual parameters and the existing vehicle body frame 162 in the profile fitting device 16, and generates the production parameters of the profile fitting component based on these differences.

[0028] Once the manufacturing parameters are determined, the contour fitting subsystem 11 sends the manufacturing parameters to the contour fitting device 16 through the first wireless communication device 164. The robot arm 161 in the contour fitting device 16 uses reusable materials such as resin clay and paper clay with appropriate plasticity and strength to make contour fitting parts according to the manufacturing parameters, and performs polishing. After that, the contour fitting parts are attached to the specified position of the existing body frame 162 by the robot arm 161.

[0029] After the fitting is completed, the entire existing body frame 162 is scanned by laser radar to obtain the contour fitting parameters of the vehicle exterior and interior after contour fitting. The contour fitting subsystem 11 compares and analyzes the contour fitting parameters with the vehicle design parameters or the actual parameters of the vehicle. If there is a difference, the system will recalculate the production parameters and manufacture new contour fitting parts until the difference between the two meets the design requirements.

[0030] After the vehicle contour fitting work is completed, the robot arm 161 will also install the human-computer interaction facility 163 with wireless communication capability to the specified position of the existing vehicle body frame 162, and ensure that it can achieve wireless communication and data interaction with the management subsystem 14.

[0031] At the same time, the multimodal enhancement subsystem 12 also obtains the vehicle comprehensive parameters and pre-set key detection points through the API interface 15 according to the vehicle model selected by the user in the management subsystem 14. The key detection points refer to the test drive parts that require special attention when detecting the user's emotional state, such as the push-back feeling of the seat during acceleration, the vibration feeling inside the car when the road vibrates, the layout of the instrument panel and display screen, etc.

[0032] The multi-modal enhancement subsystem 12 extracts parameters such as the electrical system, mechanical system, and power performance from the acquired vehicle comprehensive parameters, and generates a test drive simulation program in combination with the test drive environment parameters set by the user, such as the surrounding environment, road conditions, and weather, to generate a test drive scenario that conforms to reality.

[0033] The test drive simulation program generates hardware configuration information according to the electrical system parameters, mechanical system parameters and power system parameters corresponding to the vehicle model, and sends the hardware configuration information to the multimodal wearable device 171 and the environmental simulation device 172 of the multimodal device 17 through the wireless communication device to initialize the local configuration. The staff also uses the multimodal wearable device 171 to experience the visual and tactile sense of the appearance, interior and human-computer interaction facilities of the vehicle after augmented reality, and modifies the vehicle design parameters or actual parameters of the augmented reality configuration through the multimodal augmentation subsystem 12 until the design and experience requirements are met.

[0034] After the user starts the test drive simulation program, he can experience the appearance and interior of the simulated vehicle generated by the contour fitting subsystem 11 and the device through the multimodal wearable device 171, and experience the driving experience in different environments through the environmental simulation device 172. The environmental simulation device 172 can be set to a hemispherical environmental simulation display screen with a diameter greater than 6 meters. The user can obtain real visual, auditory, olfactory, tactile, acceleration and deceleration, road vibration, turning inertia, sense of position, wind sense and other multi-sensory experiences through the multimodal wearable device 171 and the environmental simulation device 172.

[0035] During the test drive experience after the user starts the test drive simulation program, the EEG acquisition device 181 of the brain-computer interface device 18 obtains corresponding detection information according to key detection points. The detection information is all emotional information of the user at all key detection points.

[0036] The management subsystem 14 obtains the simulated behavior information of each simulated action of the test drive simulation program according to the test drive simulation program, associates and binds the detection information and the simulated behavior information to obtain associated information, and sends the bound associated information to the brain-computer interface subsystem 13, and determines the emotional state information of each key detection point during the user's test drive through the emotional analysis program.

[0037] The brain-computer interface subsystem 13 feeds back the emotional state information and related simulated behavior information of each key detection point to the automobile design or production link through the API interface 15, helping them to accurately understand the user's real experience of automobile design and use.

[0038] The embodiment of the present invention determines the target vehicle model, obtains the vehicle comprehensive parameters and key detection points through the application programming interface according to the target vehicle model, generates the target vehicle and the test drive simulation program after profile fitting according to the vehicle comprehensive parameters, obtains the detection information corresponding to the key detection points, obtains the emotional state information of each key detection point according to the detection information, and the emotional state information is used to reflect the user's emotional state at each key detection point. Therefore, through the collaborative cooperation of multiple systems, the test drive road conditions can be enriched, the test drive time can be extended, and the test drive experience effect and test drive service quality can be improved.

[0039] Traditional vehicle maintenance and customization processes often rely on manual measurement and production, which is not only inefficient but also prone to errors. In addition, for the development and customization of new models, it is necessary to quickly and accurately obtain the vehicle's profile and detailed design information for subsequent manufacturing and assembly. Therefore, the embodiment of the present invention achieves the rapid acquisition of vehicle comprehensive parameters, the accurate calculation of production parameters and the efficient production of profile fitting components through the collaborative work between the profile fitting subsystem, the management subsystem and the profile fitting device, which not only improves the efficiency and quality of vehicle maintenance and customization, but also provides strong technical support for the development and customization of new models.

[0040] Figure 2 4 is an information interaction diagram of a first example of a test drive simulation system according to an embodiment of the present invention. Figure 2 A flow chart showing the information interaction between the profile fitting subsystem, the management subsystem and the profile fitting device is shown, which specifically includes the following steps: Step S101: The management subsystem determines a target vehicle model.

[0041] Specifically, the user can first log in to the management subsystem through a suitable authentication method. After successful login, the user will enter the main interface of the management subsystem and select the target model to be test-driven. After receiving the user's test-drive request, the management subsystem parses and processes the request and extracts the target model selected by the user from the request.

[0042] Step S102: The contour fitting subsystem obtains the target vehicle model.

[0043] Specifically, after receiving the target vehicle model sent by the management subsystem, the contour fitting subsystem parses and processes the information.

[0044] Step S103: The contour fitting subsystem calls an API interface to obtain comprehensive vehicle parameters.

[0045] Specifically, the contour fitting subsystem calls the API interface according to the target vehicle model to retrieve the corresponding vehicle comprehensive parameters from the database including vehicle comprehensive parameters and key detection points. The vehicle comprehensive parameters are vehicle design parameters or vehicle actual parameters, and the vehicle comprehensive parameters include appearance parameters, interior parameters, electrical system parameters, mechanical system parameters and power system parameters. The vehicle design parameters refer to the parameters of the vehicle model that has not been mass-produced, and the vehicle actual parameters refer to the parameters of the vehicle model that has been mass-produced. When the target vehicle model selected by the user is a new model that is still in the new product research and development design stage, the vehicle comprehensive parameters obtained are the vehicle design parameters. When the target vehicle model selected by the user is a vehicle model that has been mass-produced, the vehicle comprehensive parameters obtained are the vehicle actual parameters.

[0046] Step S104: the contour fitting device sends the existing vehicle body frame.

[0047] Specifically, after the contour fitting device obtains the instruction sent by the contour fitting subsystem through the wireless communication device, the existing body frame is sent to the contour fitting subsystem. The existing body frame is a basic body structure model that usually has undergone preliminary design or standardized design and can be applicable to most vehicle models. It includes the basic shape, size and some key design features of the body.

[0048] Step S105: The contour fitting subsystem obtains the existing vehicle body frame.

[0049] Specifically, the contour fitting subsystem obtains the existing vehicle body frame sent by the management subsystem.

[0050] Step S106: The contour fitting subsystem obtains production parameters.

[0051] Specifically, the contour fitting subsystem extracts the appearance parameters and interior parameters based on the acquired comprehensive vehicle parameters, combines the appearance parameters and interior parameters with the existing vehicle body frame, calculates the gap between the existing vehicle body frame and the appearance parameters and interior parameters, and obtains the production parameters based on the gap.

[0052] Step S107: The contour fitting subsystem sends production parameters.

[0053] Specifically, the contour fitting subsystem sends the production parameters to the management subsystem.

[0054] Step S108: The contour fitting device obtains production parameters.

[0055] Specifically, the contour fitting device obtains the production parameters sent by the management subsystem.

[0056] Step S109: The contour fitting device manufactures a contour fitting component according to the manufacturing parameters.

[0057] Specifically, the robot arm of the contour fitting device manufactures the contour fitting component according to the manufacturing parameters and performs polishing, and the contour fitting component is a reusable clay material with suitable plasticity and strength, such as resin clay, paper clay, etc.

[0058] Step S110: The contour fitting device generates a target vehicle after contour fitting.

[0059] Specifically, the robot arm of the contour fitting device fits the manufactured contour fitting component to the specified position of the existing vehicle body frame, and then obtains the contour fitting parameters of the target vehicle after contour fitting through laser radar scanning imaging, and compares and analyzes the contour fitting parameters of the target vehicle after laser radar scanning with the vehicle design parameters or the actual parameters of the vehicle. If there is a difference, repeat steps S106-S109 until the difference between the contour fitting parameters of the target vehicle and the vehicle design parameters or the actual parameters of the vehicle meets the design requirements.

[0060] Step S111: The contour fitting device installs human-computer interaction facilities.

[0061] Specifically, the robot arm of the contour fitting device will be able to carry out wireless communication with human-computer interaction facilities, such as dashboards, display screens and other equipment, and will be installed at the designated position of the target vehicle according to the car design parameters or the actual parameters of the car, and realize wireless communication and data interaction with the management subsystem.

[0062] Traditional test drive methods can often only provide limited driving experience and vehicle performance information, and cannot meet the user's needs for a comprehensive and in-depth experience of the vehicle. The user's emotional state has an important impact on the driving experience. This embodiment can more accurately understand the user's feelings and evaluation of the vehicle by real-time monitoring of the user's emotional state during the test drive, providing valuable feedback for vehicle design and production.

[0063] Figure 3 4 is an information interaction diagram of a second example of a test drive simulation system according to an embodiment of the present invention. Figure 3 A flowchart of information interaction between a multimodal enhancement subsystem, a management subsystem, a brain-computer interface subsystem, a multimodal device, and a brain-computer interface device is shown, specifically including the following steps: Step S201: The management subsystem determines the target vehicle model.

[0064] Step S202: The multimodal enhancement subsystem obtains a target vehicle model.

[0065] Specifically, the specific implementation of steps S201-S202 can refer to the above steps S101-S102. Steps S201-S202 are performed simultaneously with steps S101-S102, and will not be repeated in this embodiment.

[0066] Step S203: The multimodal enhancement subsystem calls an API interface to obtain comprehensive vehicle parameters and key detection points.

[0067] Specifically, in addition to calling the API interface to retrieve the corresponding vehicle comprehensive parameters from the database according to the target vehicle model, the multimodal enhancement subsystem also needs to obtain key detection points. The database of this embodiment is the same as the database in step S103, both of which include vehicle comprehensive parameters and key detection points. When multimodal reality enhancement is required, in addition to extracting the electrical system parameters, the mechanical system parameters and the power system parameters in the vehicle comprehensive parameters, it is also necessary to extract key detection points. The key detection points refer to the test drive parts or vehicle characteristics that need special attention when detecting the user's emotional state. The key detection points are usually directly related to the user's sensory experience and can reflect the performance and user experience of the vehicle in a specific environment. For example, the key detection point is the seat during acceleration. When the user steps on the accelerator pedal, if the seat can give an obvious push back feeling, it means that the vehicle has good acceleration performance and can bring a pleasant driving experience to the user; the key detection point is the vibration inside the car when the road vibrates. When the vehicle is driving on an uneven road, if the vibration inside the car is too obvious, it may affect the user's driving comfort and emotional state; the key detection point is the cooling or heating effect of the air-conditioning system. During the test drive under extreme weather conditions, the cooling or heating effect of the air-conditioning system will directly affect the user's comfort and emotional state.

[0068] Step S204: The multi-modal enhancement subsystem generates a test drive simulation program according to the comprehensive vehicle parameters.

[0069] Specifically, the multimodal enhancement subsystem extracts electrical system parameters, the mechanical system parameters, and the power system parameters from the acquired vehicle comprehensive parameters. The multimodal enhancement subsystem obtains preset environmental parameters set by the user, and generates a test drive simulation program based on the electrical system parameters, the mechanical system parameters, the power system parameters, and the preset environmental parameters. The test drive simulation program simulates the running state of the car based on the electrical system, mechanical system, and power performance parameters, and dynamically adjusts the visual effects and sound effects in the simulation scene based on the environmental parameters.

[0070] Among them, the electrical system parameters may include battery power, motor performance, circuit layout, etc. The mechanical system parameters may control the parameters of the suspension system, steering system, and brake system, etc. The power system parameters may include engine performance, fuel efficiency, transmission characteristic parameters, etc. The preset environmental parameters may include weather conditions, such as sunny, rainy, and snowy days, road conditions, such as flat, rugged, and curved roads, traffic conditions, such as congestion and smooth traffic, and time, such as day and night.

[0071] Step S205: The multimodal enhancement subsystem determines hardware configuration information.

[0072] Specifically, during the test drive simulation program generation process, the multimodal enhancement subsystem analyzes and determines the hardware configuration information required to run the test drive simulation program, which may include the required sensor type, resolution requirements, audio output devices, etc. The hardware configuration information is determined based on the complexity of the test drive simulation program and the demand for multimodal interaction to ensure that the simulation program can run smoothly on multimodal wearable devices and other hardware facilities.

[0073] Step S206: The multimodal enhancement subsystem sends hardware configuration information.

[0074] Specifically, the multimodal enhancement subsystem sends the hardware configuration information to the multimodal device through a wireless communication device.

[0075] Step S207: The multimodal device hardware facilities perform local configuration initialization.

[0076] Specifically, the multimodal wearable device and the hardware facilities are initialized and configured according to the acquired hardware configuration information to ensure that all components can work together according to the configuration requirements. When the initialization configuration is completed, the hardware facilities are ready to run the test drive simulation program, and the user can start the program and start the test drive simulation experience.

[0077] Step S208: The multi-modal device performs a multi-modal simulated test drive.

[0078] Specifically, the user starts the configured test drive simulation program through a multimodal wearable device or other designated hardware facilities. Once the program is started, the user will see an intuitive program interface that provides a wealth of setting options, allowing the user to customize the test drive environment parameters. In the program interface, the user can freely select environmental parameters such as weather conditions, road conditions, traffic conditions, and time. The setting of these parameters will directly affect the realism and challenge of the simulated driving scene. In order to obtain the best test drive experience, the user needs to wear a multimodal wearable device containing various sensors. These devices can not only collect the user's physiological data in real time, but also capture the user's motion data. More importantly, these devices can also provide users with visual, auditory, tactile and other sensory feedback, making the user feel as if they are in a real driving environment. After the user wears the device and sets the environmental parameters, he can enter the simulated driving environment through the multimodal wearable device and the environmental simulation device. The environmental simulation device, such as a hemispherical environmental simulation display with a diameter greater than 6 meters, will present a realistic driving scene to the user. The content on the display screen can show dynamic driving scenes, such as vehicles driving, pedestrians crossing the road, weather changes, etc. Users can directly feel the driving environment outside the vehicle with their naked eyes without any auxiliary wearable devices.

[0079] In addition, in order to simulate the real driving experience, we also placed the target vehicle on the machine. This machine can accurately control the running state and driving experience of the simulated vehicle according to the vehicle's electrical system parameters, mechanical system parameters, and power system parameters. For example, when the user steps on the accelerator pedal, the machine will simulate the acceleration process of the vehicle and provide the user with corresponding tactile and auditory feedback through multimodal wearable devices.

[0080] Step S209: The multimodal enhancement subsystem sends key detection points.

[0081] Specifically, the multimodal enhancement subsystem sends the key detection points to the management subsystem.

[0082] Step S210: The brain-computer interface device obtains key detection points.

[0083] Specifically, the brain-computer interface device obtains key detection points sent by the management subsystem.

[0084] Step S211: The brain-computer interface device obtains detection information.

[0085] Specifically, during the user's test ride, the EEG acquisition device of the brain-computer interface device determines the key detection point information based on the key detection point, and the EEG acquisition device detects the user's emotional state in real time based on the key detection point information to obtain the user's emotional signal, which is directly derived from the user's brain activity and is a direct reflection of the user's emotional state at the physiological level. The signal processing device analyzes and processes the information to generate detection information containing the user's emotional state information.

[0086] Step S212: The brain-computer interface device sends detection information.

[0087] Specifically, the brain-computer interface device sends the generated detection information to the management subsystem.

[0088] Step S213: The management subsystem obtains simulation behavior information.

[0089] Specifically, the management subsystem obtains the simulated behavior information of the test drive simulation program. The simulated behavior information refers to the simulated behavior information generated during the operation of the test drive simulation program based on the user's steering wheel rotation, accelerator and brake pedal stepping and environmental parameters. The simulated behavior information may include the vehicle's acceleration, deceleration, steering, braking and other driving behaviors, as well as related vehicle speed, acceleration, steering angle and other information.

[0090] Step S214: The management subsystem obtains related information.

[0091] Specifically, the management subsystem obtains the associated information according to the detection information and the simulated behavior information. The associated information refers to matching and corresponding the detection information with the simulated behavior information to reveal the relationship between the user's emotional state and driving behavior during the test drive.

[0092] Step S215: The management subsystem sends associated information.

[0093] Specifically, the management subsystem sends the acquired associated information to the brain-computer interface subsystem.

[0094] Step S216: The brain-computer interface subsystem obtains the emotional state information of each key detection point.

[0095] Specifically, the brain-computer interface subsystem determines the emotional state of each key detection point during the user's test ride and test drive according to the associated information through an emotion analysis program, and obtains the emotional state information of each key detection point.

[0096] Step S217: The brain-computer interface subsystem generates and outputs test drive feedback.

[0097] Specifically, the brain-computer interface subsystem further integrates the emotional state information and related simulated behavior information of each key detection point to generate test drive feedback. The brain-computer interface subsystem sends the test drive feedback to relevant personnel in the automobile design or production process through the API interface. Staff can use this report to gain an in-depth understanding of the user's real experience during the test drive, thereby discovering potential design defects or points for improvement. For example, if the report indicates that the user feels overly nervous at a certain speed, then the designer can consider improving the vehicle's suspension system or noise control to improve the user's driving comfort.

[0098] The embodiment of the present invention determines the target vehicle model, obtains the vehicle comprehensive parameters and key detection points through the application programming interface according to the target vehicle model, generates the target vehicle and the test drive simulation program after profile fitting according to the vehicle comprehensive parameters, obtains the detection information corresponding to the key detection points, obtains the emotional state information of each key detection point according to the detection information, and the emotional state information is used to reflect the user's emotional state at each key detection point. Therefore, through the collaborative cooperation of multiple systems, the test drive road conditions can be enriched, the test drive time can be extended, and the test drive experience effect and test drive service quality can be improved.

[0099] Figure 4 4 is a flow chart of a test drive simulation method according to an embodiment of the present invention. Figure 4 The test drive simulation method shown specifically includes the following steps: Step S410: Determine the target vehicle model.
