Motorcycle Reverse Assist Brake Control for Stable Backing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Riders face challenges in reversing a saddle riding vehicle due to the need for multiple inputs and risk of losing footing, especially on motorcycles with high seats or uneven surfaces, as they rely on manual control of the front brake and suspension to maneuver the vehicle backward.
Innovation Solution
A reverse assist system for saddle riding vehicles that includes a switch, a sensing unit, and a controller to automatically control the front brake based on vehicle speed and acceleration, facilitating a controlled reversing process by activating a reverse assist strategy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rider manually controls the front brake and suspension to reverse the vehicle, then the rider can maneuver the vehicle backward, but the rider requires multiple inputs and risks losing footing
Solution Approach 1:
The system enables self-service operation by using sensors to automatically detect vehicle state and control brake application, eliminating the need for complex manual inputs from the rider during reversing operations
Solution Approach 2:
The patent replaces the mechanical manual brake control system with an automated electronic control system that uses sensors and a controller to manage brake application based on detected vehicle acceleration and state
2Reliability
If the rider applies the front brake and throws weight forward to compress suspension, then the vehicle can be propelled rearward, but the rider may lose footing due to seat height or gravel
Solution Approach 1:
The system performs the reversing function automatically by detecting vehicle acceleration and controlling brake application, eliminating the need for the rider to perform physical actions that could cause losing footing
Solution Approach 2:
The controller acts as an intermediary between the rider's reverse request and the brake system, automatically managing the complex sequence of brake applications and suspension compression without requiring direct rider intervention
3Ease of operation
If the rider repeats the brake and suspension sequence multiple times, then the desired vehicle position is achieved, but the process requires significant rider input and skill
Solution Approach 1:
The system automatically performs the reversing function by continuously monitoring vehicle acceleration and controlling brake application, eliminating the need for repeated manual sequences
Solution Approach 2:
The system uses acceleration sensors to provide feedback on vehicle motion state, allowing the controller to automatically adjust brake application timing and duration to achieve the desired reversing effect without manual repetition

AI summary
A reverse assist system for a saddle riding vehicle includes a switch configured to be displaced between a first position and a second position. The switch is displaced to the second position to activate a reverse assist strategy. The reverse assist system also includes a sensing unit to determine at least one of a speed or an acceleration of the saddle riding vehicle, and a controller arranged in communication with the switch, the sensing unit, and a front brake. The controller is configured to activate the reverse assist strategy in response to the displacement of the switch to the second position, and control the front brake to control braking of a front wheel based on at least one of the speed or the acceleration of the saddle riding vehicle to assist a rider to reverse the saddle riding vehicle according to the reverse assist strategy.
