Description

Technical Field

[0001] The invention relates to the technical field of automobile driving simulators, in particular to an integrated circuit control system for an automobile driving simulator. Background Art

[0002] As an advanced virtual reality system, the car simulator is designed to simulate the real driving experience and provide a safe and controllable training environment for drivers. This technology is widely used in many fields such as driver training, automobile research and development, entertainment experience, etc., and is gradually becoming an indispensable tool in the automotive industry and education. The car driving simulator integrated line control system is a high-tech system that integrates multiple key technical fields such as data acquisition, signal processing, human-computer interaction, vehicle dynamics simulation and real-time simulation. The system uses a single-chip microcomputer for signal acquisition and processing, and displays vehicle status information in real time through a human-computer interaction interface to simulate a real driving environment.

[0003] Existing car simulators cannot provide sufficiently realistic feedback due to hardware limitations, which is different from the real driving experience. They are still limited in terms of full immersive experience and cannot fully replicate all the sensory experiences in real driving. Therefore, a comprehensive line control system for car driving simulators is needed. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides an integrated circuit control system for a car driving simulator, which solves the problems of being unable to provide sufficiently realistic feedback and being unable to completely replicate all sensory experiences in real driving.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A comprehensive line control system for a car driving simulator includes a material database, a car simulation road generation system, a car simulation vehicle feedback system and a safety detection system. The material database is used to store the simulated road materials of the simulator to provide the car simulation road generation system with road generation materials. The characteristics of the road generated by the car simulation road generation system will be fed back to the car simulation vehicle feedback system loaded on the car simulation vehicle device to provide the car simulation vehicle with a more realistic simulated driving effect. The safety detection system performs a safety detection on the car simulation vehicle before the car simulator is started to ensure the safety of the car simulator.

[0006] Preferably, the automobile simulation road system includes a simulation road classification module, a simulation road model generation module, a simulation road route generation module and a simulation road real-time feedback module. The simulation road model generation module and the simulation road real-time feedback module are bound to the data in the material database to generate a simulated driving environment and special feedback during the driving process.

[0007] Preferably, the car simulation ride feedback system includes a car vibration simulation module, a car shaking simulation module, a car impact simulation module and a simulation threshold control module. The car vibration simulation module, the car shaking simulation module and the car impact simulation module receive road elements provided by the simulated road real-time feedback module to send different signals to make the car simulation ride produce corresponding actions to improve the simulator's sense of immersion, and use the threshold control module to balance the values ​​output by the car vibration simulation module, the car shaking simulation module and the car impact simulation module.

[0008] Preferably, the simulation threshold control module includes an abnormal data collection unit and a simulation state containment unit, and the abnormal data collection unit sets a threshold to collect simulation action data of the automobile simulation vehicle to cooperate with the simulation state containment unit to control the automobile simulation vehicle.

[0009] Preferably, the simulated road model generation module includes a scene model generation unit and a simulation scene map repair unit, and both the scene model generation unit and the simulation scene map repair unit work in cooperation with the AI ​​big data model.

[0010] Preferably, the simulated road route generation module includes a straight lane route generation unit, a curved road route generation unit, a road planning unit and a simulated vehicle planning unit. The straight lane route generation unit and the curved road route generation unit generate routes, the road planning unit is used to combine them to generate a simulated route, and the simulated road vehicles are arranged using the simulated vehicle planning unit.

[0011] A vehicle driving simulator integrated circuit control method comprises the following steps: Step 1: Select the road type through the simulated road classification module, generate the car simulator route through the simulated road route generation module, and generate a complete simulation route through the materials in the material database through the simulated road model generation module and the simulated road real-time feedback module; Step 2: Use the safety detection system to detect whether the car simulation ride feedback system can operate normally, so as to ensure that the car simulator can operate safely during operation; Step 3: Start the car simulator and perform driving simulation. The simulated car will be affected by the simulated road real-time feedback component during driving, and the real-time feedback will be given to the simulated car seat, so that the simulated car seat will make corresponding action feedback; Step 4: When the simulated car hits the edge of the simulated road or the virtual car in the simulated road, stop the simulation immediately.

[0012] Preferably, the specific steps of generating the simulation route in step 1 are: S1. Select one of the model materials classified in the material library, and use the scene generation unit in conjunction with the AI ​​large model to arrange the landmark buildings; S2. Select one of the classified texture materials in the material library, use the simulation scene texture repair unit and the AI ​​large model to splice them, and process the splicing edges to make the texture of the virtual road more coherent; S3. Special feedback points are set in specific areas on the simulated road model, and when the simulated car passes through the feedback points, the action of the simulated car is triggered.

[0013] Preferably, in the step three, when the simulated car vehicle makes corresponding action feedback, the car vibration simulation module, the car shaking simulation module and the car impact simulation module are all sent to the simulated car vehicle via electrical signals when triggered, and the action data generated by the simulated car vehicle is supervised by the simulation threshold control module.

[0014] Preferably, the specific steps of supervising the simulation threshold control module are: S1. Set the abnormal data value to N, and collect the data of the action generated by the simulated car seat 5 times / s through the abnormal data collection unit; The data of S2 and S3 are compared with N in real time. The data greater than N is recorded as S1, S2, ... n At this time, the simulation state containment unit is used to contain the vehicle vibration simulation module, the vehicle shaking simulation module and the vehicle impact simulation module, thereby reducing the data output of the three modules to the vehicle simulation vehicle; S3, select S1, S2, ... S within 5s n The maximum cardinality S in max , through [(S1, S2...S n ) / n-(S max -N)]² gives the reduction U; S4. Subtract U from the values ​​output by the vehicle vibration simulation module, the vehicle shaking simulation module and the vehicle impact simulation module every 1 second until the output value is no longer greater than N, so that the simulated vehicle ride tends to be stable.

[0015] The present invention provides a comprehensive line control system for a vehicle driving simulator. It has the following beneficial effects: 1. The present invention uses a simulated road model generation module and a simulated road route generation module, and uses the AI ​​big data model to work together to automatically generate a simulated driving environment and special feedback during driving. This method not only improves efficiency, but also creates a richer and more coherent virtual road environment, while ensuring real feedback in different driving scenarios, and improving the training effect and practicality of the simulator.

[0016] 2. The present invention receives the road elements provided by the simulated road real-time feedback module through the car simulation ride feedback system, and sends different signals to make the car simulation ride produce corresponding actions. This design greatly improves the sense of substitution and reality of the simulator, and provides users with a more realistic simulated driving effect.

[0017] 3. Before the car simulator is started, the safety detection system of the present invention will perform a safety check on the simulated car vehicle to ensure the safety of the car simulator. In addition, the abnormal data acquisition unit and the simulation state containment unit in the simulation threshold control module collect and analyze the simulated action data of the simulated car vehicle to monitor and adjust the abnormal situation in real time, thereby further enhancing the safety of the system.
