Saddle Vehicle Link Mechanism Locking Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operability of saddle riding type vehicles is compromised when the link mechanism is restricted, leading to a discrepancy between the actual state of the vehicle and the rider's perception, especially on varying road surfaces, as the rider may not adequately recognize when the link mechanism is locked, affecting vehicle stability and control.
Innovation Solution
Incorporating a locking mechanism with a controller, state determiner, and notifying unit that locks and unlocks the link mechanism based on relative front wheel displacement, providing continuous notification to the rider and limiting engine speed when the link mechanism is locked to maintain vehicle stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the link mechanism is locked to maintain vehicle stability, then vehicle stability is improved, but the rider's awareness of the actual vehicle state deteriorates
Solution Approach 1:
The patent implements a notification device that provides feedback to the rider about the locked state of the link mechanism. When the locking mechanism restricts the link mechanism's operation, the notification device activates to inform the rider, ensuring the rider is aware of the actual vehicle state even when the mechanism is locked for stability.
2Stability of the object's composition
If the link mechanism operation is restricted to prevent roll motion, then vehicle roll control is improved, but the discrepancy between actual state and perceived state worsens
Solution Approach 1:
The notification device provides continuous feedback to the rider about whether the link mechanism operation is restricted. This ensures that even when the mechanism is locked to prevent roll motion on sloped surfaces or uneven roads, the rider receives information about the actual state, eliminating the discrepancy between perceived and actual vehicle conditions.
3Stability of the object's composition
If the locking mechanism is engaged to maintain upright position, then vehicle upright stability is improved, but the rider's perception of front wheel position accuracy worsens
Solution Approach 1:
When the locking mechanism engages to maintain the vehicle in an upright position, the notification device activates to inform the rider of this state. This feedback ensures that the rider understands the actual position relationship between the front wheels and vehicle body, even when the locking mechanism restricts the link mechanism to maintain upright stability.

AI summary
A saddle riding type vehicle that hardly causes difference between an actual state of the vehicle and a state of the vehicle recognized by the rider is provided. The saddle riding type vehicle 10 includes a vehicle body frame 12, a pair of front wheels 14L and 14R, a link mechanism 36, a locking mechanism 80, a controller 86, and a notifying unit 112. The link mechanism 36 connects the pair of front wheels 14L and 14R to the vehicle body frame 12. The locking mechanism 80 locks the link mechanism 36 by restricting operation of the link mechanism 36 and unlocks the link mechanism 36 by allowing the link mechanism 36 to operate. The controller 86 controls locking and unlocking of the link mechanism 36 by the locking mechanism 80. The notifying unit 112 notifies that the link mechanism 36 is locked while relative displacement between the pair of front wheels 14L and 14R in the vertical direction exceeds a prescribed range.
