Dual Gyroscope Stabilization for Two-Wheeled Vehicle Torque Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary mass devices for two-wheeled vehicles lack effective control over torques and angular momentums to stabilize the vehicle during various movements, such as cornering and inclines, leading to instability and potential loss of traction or overturning.
Innovation Solution
The implementation of a method using two gyroscopic instruments with controllably pivotable axes of rotation, allowing for synchronized or counteracting torques to be applied along three orthogonal vehicle axes, managed by an electrical control device to maintain continuous and steady vehicle stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single gyroscope is used for vehicle stabilization, then the device complexity is reduced, but the ability to provide controlled torques along multiple axes is insufficient
Solution Approach 1:
The stabilization system is divided into multiple independent gyroscope units, each responsible for specific torque generation along different axes. This segmentation allows each gyroscope to be simpler in design while the collective system achieves comprehensive multi-axis torque control capability.
2Reliability
If multiple gyroscopes with independent torque control are implemented, then vehicle stability during cornering and inclines is improved, but the device complexity and component mass increase
Solution Approach 1:
Multiple gyroscope units are merged into a single integrated rotating mass device with a unified control architecture. The control device coordinates the gyroscopes' rotational speeds and orientations to generate combined torque effects, reducing overall system complexity while maintaining stability performance.
Solution Approach 2:
The gyroscope system is designed to perform multiple functions: providing torque along roll axes during cornering, compensating for inclines, and maintaining vehicle stability under various operating conditions. This multi-functionality reduces the need for separate specialized components.
3Reliability
If gyroscope rotational speeds and orientations are actively controlled to compensate for vehicle movements, then vehicle stability and safety are improved, but the energy consumption increases
Solution Approach 1:
The control system adjusts gyroscope rotational speeds and orientations in periodic cycles, synchronizing with the vehicle's movement patterns. This periodic control allows the gyroscopes to efficiently counteract disturbances while minimizing continuous energy consumption compared to constant high-speed rotation.
