Lean Vehicle Stop Assistance Using Road Surface Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lean vehicles, such as motorcycles, face challenges in maintaining stability during stops due to varying road surfaces, which can lead to falls and reduced safety for both the rider and the vehicle.
Innovation Solution
A controller with an acquisition section that gathers road surface information and an execution section that executes a stop-assistance operation, including notification and posture stabilization, to help the rider maintain a stable stop posture by adjusting the vehicle's position and posture based on the road conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rider manually supports the lean vehicle when stopping, then the rider can control the vehicle, but the rider and vehicle may fall down due to unstable stop posture on varying road surfaces
Solution Approach 1:
The acquisition section acquires road surface information in advance before the stop-assistance operation is executed. This allows the system to prepare stabilization measures beforehand, ensuring the rider can stop safely even on varying road surfaces by predicting potential instability issues before they occur.
Solution Approach 2:
The execution section executes stop-assistance operations based on feedback from the acquisition section regarding road surface conditions. This closed-loop control allows the system to adjust the stop posture dynamically according to actual road surface information, maintaining stability and preventing falls.
2Stability of the object's composition
If the execution section executes stop-assistance operation based on road surface information, then the stop posture is stabilized, but the device complexity increases due to acquisition and execution sections
Solution Approach 1:
The controller integrates multiple functions into a single device: the acquisition section gathers road surface information, the execution section implements stop-assistance operations, and both work together to stabilize stop posture. This multi-functional integration achieves the desired stability without proportionally increasing overall system complexity.

AI summary
A controller (20) for an assistance system (10) configured to execute an assistance operation for a rider of a lean vehicle (1) includes an execution section (22) and an acquisition section (21). The execution section (22) operates the assistance system (10) to execute the assistance operation. The acquisition section (21) acquires a road surface information as information about a road surface (2) on which the lean vehicle (1) is traveling. The execution section (22) operates the assistance system (10) to execute, as the assistance operation, a stop-assistance operation based on the road surface information to assist the rider in stabilizing a stop posture of the rider.
