Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If online simulation training is used for vehicle driver's license exams, then training time can be reduced, but the accuracy of vehicle modeling and simulation becomes insufficient
Solution Approach 1:
The patent creates a virtual copy of the real exam vehicle by importing actual vehicle parameters into Unity3D, including wheel colliders, ordinary colliders, rigid body components, and detailed parameter settings for powertrain, gear, and vehicle status. This virtual copy replicates the physical vehicle's behavior accurately while enabling online training without time loss.
2Measurement precision
If detailed vehicle parameters and assemblies are added to improve simulation accuracy, then the complexity of the simulation model increases
Solution Approach 1:
The vehicle model is segmented into distinct functional components: wheel colliders for rotational motion, ordinary colliders for collision detection, rigid body components for physical properties, and parameter systems for powertrain, gear, and vehicle status. Each segment is configured independently with specific parameters, allowing high accuracy without overwhelming complexity.
3Manufacturing precision
If actual vehicle parameters are obtained and detailed parameter settings are configured, then the precision of the simulation model improves, but the time and effort required for model setup increases
Solution Approach 1:
The patent performs preliminary actions by obtaining actual vehicle parameters beforehand and pre-configuring the Unity3D model with all necessary assemblies and parameter settings before simulation begins. The vehicle model is prepared in advance with wheel colliders, ordinary colliders, rigid body components, and detailed parameters for powertrain, gear, and vehicle status, eliminating setup time during actual training.

AI summary
A vehicle simulation model modeling method includes the following steps: actual parameters of an exam vehicle are obtained, and thereby modeling based on the actual parameters of the exam vehicle to obtain a vehicle model. The vehicle model is imported into a Unity3D™ project and vehicle assemblies are added to the vehicle model. Vehicle start parameters, gear parameters, powertrain parameters, vehicle status parameters, engine parameters, and input coefficients are set for the vehicle model added with vehicle assemblies. In addition, an applydrive method and a carspeed method of Unity3D™ are simultaneously rewrite to calculate the torque and speed of the vehicle model, thereby obtaining the exam vehicle simulation model. By generating more precise models, making the results obtained from simulated exams more accurate, and achieve better simulation results.
