Double-Gyroscope Stabilization for Motorized Two-Wheelers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for stabilizing two-wheelers in critical driving situations, such as those used in motor vehicles, are not applicable to two-wheelers due to their unique dynamics influenced by gyroscopic effects and angular momentum changes during steering maneuvers.
Innovation Solution
A method employing two pivotable gyroscopes with parallel axes of rotation, driven by electric motors, which pivot in opposite directions to apply targeted torque to the vehicle, stabilizing it by generating a yawing moment when unstable driving behavior is detected, and slowly returning to their original position to minimize dynamic changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If targeted and asymmetrical braking of individual wheels is used, then stabilization effectiveness is improved for multi-wheel vehicles, but the system is not applicable to two-wheelers due to their unique design and dynamics
Solution Approach 1:
The stabilization system is segmented into two independent gyroscopes that can operate independently or in combination. Each gyroscope can be controlled separately to produce targeted torque vectors, allowing adaptation to two-wheeler dynamics while maintaining stabilization effectiveness.
Solution Approach 2:
Instead of using asymmetrical braking as the primary stabilization mechanism, the patent inverts the approach by using symmetrical gyroscope activation that produces asymmetrical torque effects through the physics of gyroscopic precession, making the system suitable for two-wheelers.
2Speed
If the two rotating gyros are pivoted back into their original orientation quickly, then the response time is improved, but a larger torque acts on the vehicle which may cause instability
Solution Approach 1:
The gyroscope pivoting is implemented as a controlled periodic action with two distinct phases: a fast pivoting phase to generate stabilization torque, and a slow return phase to minimize disturbance. This periodic control pattern optimizes both response time and stability.
Solution Approach 2:
The angular velocity parameter of the gyroscope pivoting is dynamically changed between two states: a high angular velocity during the stabilization phase to achieve quick response, and a low angular velocity during the return phase to maintain vehicle stability.
3Stability of the object's composition
If the gyroscopes are used to generate yawing moment for stabilization, then driving stability is improved, but the gyroscopic effects and angular momentum changes during steering maneuvers are not suitable for two-wheelers
Solution Approach 1:
The patent replaces traditional mechanical steering stabilization methods with a gyroscopic system that uses controlled angular momentum changes. The electrically-driven gyroscopes provide torque through precession rather than direct mechanical intervention, adapting the stabilization approach to two-wheeler dynamics.
Solution Approach 2:
The gyroscope system is designed to serve multiple functions: it can generate yawing moments for stabilization, it can be deactivated during normal steering maneuvers to avoid interference, and it can be activated in response to detected unstable driving behavior, making it universally applicable to two-wheeler operations.
