Driving Simulator Support With Decoupled Pitch, Roll, And Yaw
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving simulators, particularly those for Gran Turismo, fail to accurately reproduce the pitching, rolling, and yawing movements of vehicles, especially when these movements are intense, limiting the realism of the simulation experience.
Innovation Solution
A support for driving simulators is designed with a rest base, a lower plate, an upper plate, and separate movement means for pitching/rolling and yawing movements, utilizing linear actuators and guides to decouple these movements, allowing for optimized simulation of vehicle motions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If actuators are used to simulate pitching, rolling and yawing movements in a single integrated platform, then the simulator can reproduce vehicle movements, but the accuracy of reproduction is insufficient especially for intense movements
Solution Approach 1:
The movement simulation system is divided into separate functional modules: a first movement means for pitching and rolling movements, and a second movement means for yawing movements. This segmentation allows each module to be optimized independently for its specific movement type, improving overall accuracy while maintaining manageable system complexity.
Solution Approach 2:
A decoupling mechanism is introduced between the pitching/rolling movement means and the yawing movement means. This intermediary allows the two movement types to be independently controlled and combined, enabling accurate reproduction of complex vehicle movements without requiring a fully integrated rigid platform.
2Adaptability or versatility
If a single platform is used for all movements, then the structure is compact, but the excursions for intense movements are limited
Solution Approach 1:
By separating the movement simulation into distinct pitching/rolling and yawing components, each component can achieve larger excursions appropriate for its function without being constrained by the other movements. The lower plate handles pitching and rolling with appropriate excursions, while the upper plate handles yawing independently.
Solution Approach 2:
The system adds a hierarchical dimension to movement simulation by stacking movement platforms vertically. The lower plate operates in one plane for pitching and rolling, while the upper plate operates in another plane for yawing, effectively increasing the total degrees of freedom and movement range without requiring a single large complex platform.

AI summary
A support for driving simulators including a rest base, a lower plate coupled with the rest base, an upper plate coupled with the lower plate and first and second movement means. The first movement means, interposed between the rest base and a front portion of the lower plate, is configured to move the lower plate with respect to the rest base according to a pitching and/or rolling movement. The second movement means, interposed between the lower plate and the upper plate, is configured to move the upper plate with respect to the lower plate according to a yawing movement.
