[0051] The traffic simulation system provided in the embodiment of the present application can be applied to scenarios where users experience intelligent transportation. Figure 1 , Figure 1 This is a schematic diagram of an application scenario provided by an embodiment of the present application. Figure 1 The application scenario shown includes a server, two physical traffic simulation devices, and a switch. The server and the two physical traffic simulation devices can establish communication through the switch. Optionally, the server and the two physical traffic simulation devices can also establish wired communication through a physical connection line, which is not specifically limited in this application. It can be understood that the traffic simulation system 100 shown in the embodiment of the present application may include more (such as 3) or fewer (such as 1) physical traffic simulation devices. The embodiment of the present application does not specifically limit the number of physical traffic simulation devices, which is set based on the needs of the application scenario. The following description is based on the example of a traffic simulation system 100 including a service, two physical traffic simulation devices, and a switch.

[0052] For ease of description, users are divided into terminal users and server users in the following examples, where terminal users are users corresponding to the physical traffic simulation device and server users are users corresponding to the server.

[0053] Server 110: can provide computing or application services for other devices in the network. In the embodiment of the present application, based on the established simulation correspondence, after receiving the traffic role simulation selection request, a virtual intelligent traffic simulation scene including a virtual traffic simulation object is sent to the physical traffic simulation device 120 and the physical traffic simulation device 130, and a traffic simulation test scene is displayed. After sending the virtual intelligent traffic simulation scene including the virtual traffic simulation object, the state and / or control information sent by the physical traffic simulation device 120 and the physical traffic simulation device 130 is also received, and the virtual simulation scene is coordinated according to the state and / or control information.

[0054] Physical traffic simulation device 120: a device that can change the sensor directly connected to the operating component according to the corresponding operating component manipulated by the terminal user, thereby causing the change of the electrical signal. In the embodiment of the present application, it is used to send state and / or manipulation information to the server 110 according to the manipulation of the terminal user, and to display the third simulation scene to the terminal user.

[0055] The purpose of the physical traffic simulation device 130 is as described in the physical traffic simulation device 120 and will not be repeated here.

[0056] The switch 140 can provide an exclusive electrical signal path for any two network nodes connected to the switch. In the embodiment of the present application, the switch 140 is used for two-to-two communication between the server 110, the physical traffic simulation device 120 and the physical traffic simulation device 130.

[0057] In the virtual reality model-based traffic simulation system 100 provided in the embodiment of the present application, the terminal user sends a traffic role simulation selection request to the server 110 through the physical traffic simulation device 120 and the physical traffic simulation device 130. The server 110 generates corresponding virtual traffic simulation objects in the virtual intelligent traffic simulation scene based on the received traffic role simulation selection request, and then coordinates the virtual simulation scenes corresponding to the physical traffic simulation device 120 and the physical traffic simulation device 130 based on the received status and / or control information, as well as the simulation correspondence, so as to dynamically synchronize the traffic simulation test scenes between the server and each physical traffic simulation device, and realize a more realistic traffic test scene simulation.

[0058] based on Figure 1 Please continue to refer to the application scenarios shown in Figure 2 , Figure 2 This is a process 200 of a traffic simulation method provided in an embodiment of the present application. The traffic simulation method is applied to Figure 1 In the traffic simulation system 100 shown.

[0059] The following, combined Figure 2A traffic simulation method according to an embodiment of the present application is described in detail.

[0060] Step S201: receiving at least one traffic role simulation selection request sent by at least one physical traffic simulation device.

[0061] It is easy to understand that at least one physical traffic simulation device is used to represent one or more physical traffic simulation devices; at least one traffic role simulation selection request is used to represent one or more physical traffic simulation devices.

[0062] The traffic role simulation selection request is a virtual role that the user needs to experience. For example, when the traffic role simulation selection request is a bus, the user performs a traffic simulation test from the perspective of the bus.

[0063] Optionally, the role selected in the first traffic role simulation request is any role in the traffic simulation roles, including: pedestrians, buses, cars, trucks, motorcycles, bicycles, etc.; the first physical traffic simulation device is any device in the traffic physics simulation devices, including: pedestrian simulators, bus simulators, car simulators, train simulators, motorcycle simulators, bicycle simulators, etc.

[0064] It should be understood that the traffic simulation role may include more roles, and the traffic simulation device may include more types of simulators, which are not specifically limited in this application. For example, the simulation role may include a person riding a bicycle, intercity passenger transport, a tourist bus, and a car, and accordingly, the traffic simulation device may also include a bicycle simulator, an intercity passenger transport simulator, a tourist bus simulator, and a car simulator.

[0065] Optionally, the physical traffic simulation device may also be connected to six degrees of freedom, so that the physical traffic simulation device can obtain spatial parameters of the traffic simulation character through the six degrees of freedom, thereby improving the realism of the user's traffic simulation experience.

[0066] In this embodiment, the server receives multiple traffic role simulation selection requests through various types of physical traffic simulation devices, and simulates multiple types of virtual traffic simulation objects according to the received traffic role simulation selection requests to better meet the traffic simulation test requirements.

[0067] Optionally, before receiving at least one traffic role simulation selection request sent by at least one physical traffic simulation device, it also includes: in response to an operation instructing access to at least one physical traffic simulation device, detecting whether a connection is established with at least one physical traffic simulation device, and when it is detected that the connection with at least one physical traffic simulation device fails, instructing a user to set interface parameters for connection with at least one physical traffic simulation device according to the type of at least one physical traffic simulation device; when the interface parameters are set successfully, establishing a connection with at least one physical traffic simulation device to obtain at least one traffic role simulation selection request.

[0068] Exemplarily, when the server detects that it is connected to a physical traffic simulation device, it obtains parameter information of the connected physical traffic simulation device and establishes communication with the physical traffic simulation device based on the parameter information of the physical traffic simulation device. If the parameter information of the physical traffic simulation device cannot be obtained, the server-side user is instructed to set the interface parameters of the server according to the type of the physical traffic simulation device so that the interface parameters of the server and the type of the physical traffic simulation device can match, thereby identifying the physical traffic simulation device and establishing a connection with the physical traffic simulation device.

[0069] In this example, multiple physical traffic simulation device connection interfaces and multiple customizable physical traffic simulation device connection interfaces can be pre-set on the server. The server-side user can select one of the multiple physical traffic simulation device connection interfaces to access according to the type of the connected physical traffic simulation device. If the physical traffic simulation device does not have an interface corresponding to the connected physical traffic simulation device, the server-side user is instructed to select one of the multiple customizable physical traffic simulation device connection interfaces and set the interface parameters of the interface, so that the server can identify multiple types of physical traffic simulation devices.

[0070] In this embodiment, the server detects whether the connection with the physical traffic simulation device is successful, and determines whether to instruct the user to set the interface parameters of the interface according to the type of physical traffic simulation device, so that the physical traffic simulation device can promptly identify various types of physical traffic simulation devices and promptly provide users with multiple types of simulatable traffic simulation roles, thereby improving the efficiency of completing traffic simulation tests.

[0071] Step S202: Generate virtual traffic simulation objects corresponding to the traffic role simulation selection requests in the virtual intelligent traffic simulation scene.

[0072] The virtual intelligent traffic simulation scene represents the simulation scene that the user needs to experience. The virtual traffic simulation object is the traffic participant object in the virtual intelligent traffic simulation scene. Each created virtual traffic simulation object corresponds to a virtual camera, which is equivalent to the "eyes" of the virtual traffic simulation object in the virtual intelligent traffic simulation scene. The field of view of the virtual camera is equivalent to the field of view of the corresponding virtual traffic simulation object in the virtual intelligent traffic simulation scene.

[0073] Optionally, before the server generates each virtual traffic simulation object corresponding to each traffic role simulation selection request in the virtual intelligent traffic simulation scene, it also includes: obtaining scene setting information, and generating a virtual traffic simulation scene according to the scene information; or, obtaining event setting information, and generating a virtual traffic simulation scene according to the event information; or, obtaining scene setting information and event setting information, and generating a virtual traffic simulation scene according to the scene setting information and the event setting information.

[0074] The scene setting information is the simulation scene that the user needs to experience; the event setting information is the unexpected event that occurs in the simulation scene. Optionally, the event setting information also includes information such as the time, location, and severity of the unexpected event.

[0075] It is easy to understand that the user can set the virtual traffic simulation scene according to the traffic simulation test requirements. For example, when the user only sends the scene setting information, the server generates the virtual traffic simulation scene required by the user according to the scene setting information; when the user only sends the event setting information, the server generates an unexpected event in the virtual traffic simulation scene according to the event setting information; when the user sends the scene setting information and the event setting information, the server generates the simulation scene required by the user and the unexpected event that occurs in the simulation scene.

[0076] The following takes the case where a user sends scene setting information and event setting information at the same time as an example.

[0077] In an optional implementation, the scene setting information includes: at least one of road conditions, weather, traffic time period, and traffic congestion level; the event setting information includes: at least one of truck collision, road collapse, and landslide.

[0078] In the embodiment of the present application, the user can input multiple scene setting information and multiple event setting information according to the traffic simulation test requirements. For example, the information input by the user can be [scene setting information (road conditions: Road B intersects Road A and Road C, traffic congestion level: medium), event setting information (truck collision at the intersection of Road B and Road C)].

[0079] In this implementation, the server sets one or more scene setting information and event setting information according to the user's traffic simulation test requirements to generate a scene that better meets the traffic simulation test requirements, so that the results of the traffic simulation test better meet the user's needs.

[0080] In another optional implementation, the user can also set a virtual intelligent traffic simulation scene based on the actual traffic scene according to the traffic simulation test requirements. For example, the information input by the user can be [scene setting information (road conditions: Chengdong-West Road, City A, traffic congestion level: medium), event setting information (truck collision in the middle section of Chengdong-West Road, City A)].

[0081] It should be understood that users can also combine actual traffic scenarios with virtual scenarios provided by the traffic simulation system according to actual traffic simulation test requirements (e.g., adding a C Road to Chengdong-West Road in City A), and this application does not make specific limitations on this.

[0082] In this implementation, the server generates a virtual intelligent traffic simulation scene according to the scene setting information and event setting information set by the user, which can better meet the user's scene requirements for traffic simulation testing.

[0083] For example, Figure 3 As shown, the virtual intelligent traffic simulation scene is [scene setting information (road conditions: Road B intersects Road A and Road C, traffic congestion level: medium), event setting information (truck collision at the intersection of Road B and Road C)], and the traffic role simulation selection request sent by the terminal user is [ID: 001, simulation object: car, initial position: 100 meters south of Road B]. After receiving [ID: 001, simulation object: car, initial position: 100 meters south of Road B], the server determines the field of view of the car in the virtual intelligent traffic simulation scene according to the virtual camera of the created virtual traffic simulation object (car), such as determining the virtual intelligent traffic simulation scene in the perspective when the car is 100 meters south of Road B, which may specifically include but is not limited to the brightness of street lights, the height of street lights, the clarity of the accident scene, etc. in the perspective. This information will be synchronously presented on the server and the physical traffic simulator corresponding to the virtual traffic simulation object (car), thereby realizing the coordination of the status and / or interaction information of the server and the physical traffic simulator in the virtual intelligent traffic simulation scene.

[0084] Optionally, the server also displays the traffic simulation test scene, and shows the real-time status, interaction status and / or event triggering related status of each virtual traffic simulation object in the virtual intelligent traffic simulation scene in the displayed traffic simulation test scene.

[0085] For example, the traffic simulation test scenario can be as follows Figure 3Therefore, based on the traffic simulation test scenario, it is convenient for users to know the real-time status of the virtual traffic simulation object in the traffic simulation test.

[0086] Optionally, monitor whether a traffic accident is simulated in the traffic simulation test scenario; if a traffic accident occurs, update the accident information table based on the accident information of the traffic accident, and the accident information table is used to record the number of occurrences and information of various types of traffic accidents.

[0087] After monitoring whether a traffic accident is simulated in the traffic simulation test scenario, the server records [Number of traffic accidents: 1, Collision roles: truck, motorcycle, Severity level: Level 2, Location of occurrence: intersection of Road B and Road C] in the accident information table according to the type of traffic accident.

[0088] Alternatively, if Figure 3 As shown, after monitoring whether a traffic accident is simulated in the traffic simulation test scenario, the server can also display part of the accident information at the location where the traffic accident occurs in the traffic simulation test scenario.

[0089] It should be understood that the accident information table may include more or less information, and this application does not make any specific limitation on this.

[0090] In this embodiment, the server records the number and information of various accidents, so that users can analyze in which traffic scenarios they are prone to accidents and the causes of accidents after completing the traffic simulation experience, thereby reducing the risk of accidents in actual travel.

[0091] Step S203: establishing a simulation correspondence between the virtual traffic simulation object and the physical traffic simulation device.

[0092] The simulation correspondence is used to determine the relationship between the virtual traffic simulation object and the physical traffic simulation device. After generating the simulation scene, the server can send the simulation scene to the corresponding physical traffic simulation device according to the simulation correspondence.

[0093] Exemplarily, the simulation correspondence may be [first virtual traffic simulation object, ID: 001]. After generating the simulation scene, the server sends the simulation scene to the physical traffic simulation device coded as 001 according to the simulation correspondence.

[0094] Optionally, when inputting information, the user may input the device code of the first physical traffic simulation device used, or after the user sends the information, the device code may be added to the information sent by the user. This application does not make specific limitations on this.

[0095] Step S204: Acquire status and / or control information sent by at least one physical traffic simulation device.

[0096] Step S205: Determine the state and / or interaction data of the corresponding virtual traffic simulation object in the virtual intelligent traffic simulation scene according to the state and / or control information sent by at least one physical traffic simulation device.

[0097] The state and / or manipulation information is used to indicate the parameters input for adjusting the virtual traffic simulation object when the user changes the current posture of the virtual traffic simulation object. In an embodiment of the present application, if the physical traffic simulation device is a wearable device, the physical traffic simulation device sends state information, and when the physical traffic simulation device is a manipulation device, the physical traffic simulation device sends manipulation information. For example, when the virtual traffic simulation object is a pedestrian, the physical traffic simulation device sends state information to the server based on the user's real-time posture; when the physical traffic simulation device is a car, the manipulation information is sent to the server based on the user's manipulation of the car.

[0098] The state data in the state and / or interaction data is used to represent the data of the virtual traffic simulation object itself, and the interaction data is used to represent the impact of other objects in the virtual simulation scene on itself. Figure 3 As shown, the virtual traffic simulation object is a truck operated by user B, and its corresponding state data is [direction: right, position: intersection of Road B and Road C, speed: 0, truck collision volume: level one], and the interaction data is [car light intensity: level two].

[0099] by Figure 3 Taking the car operated by user A as an example, the state of the car is [position: 100 meters south of Road B, speed: 60KM / H]. Based on the simulation scene displayed by the physical traffic simulation device, user A finds a truck collision in front of him, and adjusts the speed to 30KM / H by manipulating the car simulation model. The physical traffic simulation device sends state and / or control information [ID: 001, speed: 30KM / H] to the server. After receiving the state and / or control information, the server determines that the state and / or interaction data of the car is [position: 80 meters south of Road B, direction: front of the car facing left, speed: 30KM / H, truck collision volume: level two].

[0100] Step S206: Send the simulation correspondence and the status and / or interaction data in the virtual intelligent traffic simulation scene to at least one physical traffic simulation device to achieve collaboration of the virtual simulation scene between the server and at least one physical traffic simulation device.

[0101] Collaboration is used to indicate that the server updates the virtual simulation scene of the corresponding physical traffic simulation device according to the status and / or interaction data of the virtual traffic simulation object in the virtual intelligent traffic simulation scene, and simultaneously updates the virtual simulation scenes of other physical traffic simulation devices according to the relationship between the virtual traffic simulation object and other virtual traffic simulation objects.

[0102] The traffic simulation method provided in the embodiment of the present application can generate a virtual traffic simulation object in a virtual intelligent traffic simulation scene in response to a traffic role simulation selection request, so as to satisfy the relationship between the virtual traffic simulation object and the intelligent traffic simulation scene in the traffic simulation test; and establish a simulation correspondence relationship based on the relationship between the virtual traffic simulation object and the physical traffic simulation device. After determining the state and / or interaction data of the virtual traffic simulation object in the virtual intelligent traffic simulation scene, the virtual simulation scene corresponding to the physical traffic simulation device can be quickly coordinated to improve the real-time performance of the traffic simulation test interaction process, thereby meeting the user's requirements for the traffic simulation test.

[0103] Optionally, at least one physical traffic simulation device includes multiple physical traffic simulation devices; sending simulation correspondences and status and / or interaction data in a virtual intelligent traffic simulation scene to at least one physical traffic simulation device to achieve collaboration of virtual simulation scenes between a server and at least one physical traffic simulation device, including: sending respective simulation correspondences to each of the multiple physical traffic simulation devices, and status and / or interaction data of virtual traffic simulation objects corresponding to each physical traffic simulation device in the virtual intelligent traffic simulation scene to achieve collaboration of virtual simulation scenes between the server and each physical traffic simulation device.

[0104] Optionally, at least one physical traffic simulation device includes multiple physical traffic simulation devices; obtaining status and / or control information sent by at least one physical traffic simulation device, and determining the status and / or interaction data of at least one virtual traffic simulation object in the virtual intelligent traffic simulation scene based on the status and / or control information, including: determining the time-space relative relationship of multiple virtual traffic simulation objects corresponding to the multiple physical traffic simulation devices in the virtual intelligent traffic simulation scene; determining the status and / or interaction data of multiple virtual traffic simulation objects in the virtual intelligent traffic simulation scene based on the time-space relative relationship and the status and / or control information of the multiple physical traffic simulation devices.

[0105] For example, Figure 3As shown, the traffic simulation scene includes three physical traffic simulation devices, namely a truck, a motorcycle, and a car. The truck and the motorcycle operated by the user collide at the intersection of Road B and Road C. The server determines the status and / or interaction data of the truck, the motorcycle, and the car according to the relative time and space relationship between the truck, the motorcycle, and the car, respectively [direction: right, position: intersection of Road B and Road C, speed: 0, car light intensity: level 2, truck collision volume: level 1], [direction: left, position: intersection of Road B and Road C, speed: 0, car light intensity: level 1, truck collision volume: level 1], [direction: left, position: 80 meters south of Road B, speed: 30KM / H, truck collision volume: level 2]. When the server performs virtual simulation scene collaboration, it sends the truck to the The virtual simulation scene sent by the corresponding physical traffic simulation device is that itself is stationary at the intersection of Road B and Road C, the volume of the truck collision heard is level one, it is facing the front of the motorcycle, the car is driving towards itself at 30KM / H, and it is illuminated by the second-level brightness light emitted by the car; the virtual simulation scene sent to the physical traffic simulation device corresponding to the motorcycle is that itself is stationary at the intersection of Road B and Road C, the volume of the truck collision heard is level one, it is facing the front of the truck, the car is driving behind itself at 30KM / H, and it is illuminated by the first-level brightness light emitted by the car; the virtual simulation scene sent to the physical traffic simulation device corresponding to the car is that itself is driving forward at 30KM / H 80 meters south of Road B, the volume of the truck collision heard is level one, and it is facing the front of the truck and the rear of the motorcycle.

[0106] In this embodiment, the server determines the impact of the status and / or control information on multiple virtual traffic simulation objects based on the relative temporal and spatial relationship of the multiple virtual traffic simulation objects in the virtual intelligent traffic simulation scene, which can improve the user's experience during the traffic simulation test, and improve the accuracy of the impact of various traffic factors on various types of pedestrians in the traffic simulation test results.

[0107] It should be understood that the server can also establish communications with more physical traffic simulation devices and coordinate virtual simulation scenes corresponding to multiple physical traffic simulation devices based on a larger number of status and / or interaction data. This application does not make specific limitations on this.

[0108] In this embodiment, the server can receive multiple traffic role simulation selection requests, and simulate multiple virtual traffic simulation objects according to the traffic role simulation selection requests, so that multiple users can interact in the traffic simulation test, thereby improving the authenticity of the traffic simulation test results.

[0109] Optionally, the multiple physical traffic simulation devices include: different types of physical traffic simulation devices, and / or multiple physical traffic simulation devices of the same type. In this embodiment, the server does not limit the type of physical traffic simulation device connected, and can provide users with more virtual traffic simulation objects, thereby meeting the user's diverse traffic simulation test needs.

[0110] Optionally, before receiving at least one traffic role simulation selection request sent by at least one physical traffic simulation device, it also includes: obtaining a preset instruction rule, the preset instruction rule is used to determine the meaning of the control instruction code sent by at least one physical traffic simulation device, so as to respond to at least one physical traffic simulation device according to the determined meaning.

[0111] In combination with the above, the preset instruction rules are [(car turns right-00), (acceleration 1m / s-01), (turn left-03)]. When the first virtual traffic simulation object (car) turns right, the status and / or control information sent to the server is

[00] . After the server receives

[00] , there is no need to parse the status and / or control information sent by the first physical traffic simulation device. The status of the first virtual traffic simulation object can be directly updated according to the preset instruction rules to improve the real-time response to user operations.

[0112] like Figure 3 As shown, the virtual intelligent traffic simulation scene including the virtual traffic lights is divided into three groups, and the update order is group 1, group 2, and group 3.

[0113] Exemplarily, because a traffic accident is simulated at the intersection of Road B and Road C, the color of the virtual traffic lights at the intersection of Road B and Road C is set to red, the color of the traffic lights in Group 1 is set to green, and the colors of the traffic lights in Groups 2 and 3 are set to red. When the server updates the simulation scene, it first updates the color of the traffic lights in Group 1 to green, and the colors of the traffic lights in Groups 2 and 3 remain unchanged. The updated simulation scene is sent to the first physical traffic simulation device, and then a traffic simulation scene is generated in which the color of the traffic lights in Group 1 is green, the color of the traffic lights in Group 2 is red, and the color of the traffic lights in Group 3 remains unchanged. The generated traffic simulation scene is sent to the physical traffic simulation device, and then a traffic simulation scene is generated in which the color of the traffic lights in Group 1 is green, and the color of the traffic lights in Group 2 is red, and the color of the traffic lights in Group 3 remains unchanged. The generated traffic simulation scene is sent to the physical traffic simulation device, thereby completing the update of the traffic simulation scene from the perspective of the physical traffic simulation device.

[0114] In this embodiment, by setting an update order for virtual traffic signals, etc., the display parameters corresponding to the virtual traffic signals that need to be calculated each time the server updates can be reduced, thereby increasing the speed at which the server updates the traffic simulation model and the panoramic simulation model.

[0115] Optionally, the physical traffic simulation device can also enhance the three-dimensional simulation effect of the virtual character by connecting to six degrees of freedom and VRKAT, for example, the vehicle state of the car when it is bumpy, uphill or downhill.

[0116] It is easy to understand that when the physical traffic simulation device sends user status parameters to the physical traffic simulation device through multiple sensors, some user postures may not be captured, resulting in incomplete user status parameters obtained by the server, causing the virtual character's posture to be unrealistic.

[0117] Optionally, the inverse function in the Finak IK technology can be used to determine the posture of the virtual character when the virtual traffic simulation object is a pedestrian.

[0118] In some embodiments, the server also stores status data of the user during the simulation.

[0119] The state data can be understood as the physiological data of the user during the traffic simulation test. For example, the state data can be the user's heart rate, breathing rate, blood pressure, body temperature, etc. during the experience.

[0120] In this embodiment, the server stores the user's status data during the simulation process, so that the user can determine whether to adjust the travel mode according to whether the status data is normal.

[0121] Optionally, when the user clicks to view the virtual character information in the traffic simulation test scene, the information of the clicked virtual character can be displayed to the user.

[0122] The above describes an embodiment of an intelligent traffic simulation method applied to a server provided by the present application. Below, the present application provides an embodiment of a traffic simulation method applied to a physical traffic simulation device.

[0123] The implementation process is: responding to the virtual simulation instruction issued by the user, sending a traffic role simulation selection request to the server; responding to the user's own manipulation, generating a first state and / or control information and sending it to the server, so that the server can drive the state and / or interaction of the corresponding virtual traffic simulation object in the virtual intelligent traffic simulation scene according to the state and / or control information; receiving and displaying the virtual traffic simulation environment sent by the server and the state and / or interaction data of the corresponding virtual traffic simulation object in the virtual traffic simulation environment.

[0124] By adopting the above method, the corresponding physical traffic simulation device can be selected according to the virtual traffic simulation object selected by the user, and the simulation test process can be displayed to the user through communication with the server, thereby improving the authenticity of the user when performing traffic simulation testing and further improving the authenticity of the traffic simulation test results.

[0125] Optionally, the status and / or interaction data of other virtual traffic simulation objects in the virtual traffic simulation environment sent by the server are received and displayed.

[0126] By adopting the above method, the physical traffic simulation device can realize the interaction of multiple users by synchronizing the corresponding control information of other physical traffic simulation devices, which can better meet the needs of traffic simulation testing.

[0127] Optionally, before responding to the virtual simulation instruction issued by the user and sending the first traffic role simulation selection request to the server, it also includes: setting a control instruction code for the physical traffic simulation device according to a preset instruction rule.

[0128] By adopting the above method, the speed at which the server feeds back information according to virtual simulation instructions can be improved, further ensuring the authenticity and accuracy of traffic simulation test results.
