Motorcycle Steering Assistance Control for Front-Wheel Kickback Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering damper systems in single-track vehicles only attenuate kickbacks, failing to prevent them entirely, and there is a need for a method to completely eliminate kickbacks during wheel lift-off.
Innovation Solution
A method and device that uses a control unit to continuously monitor vehicle parameters and adjust the steering angle to prevent kickbacks by aligning the wheel before it lands, utilizing sensors to detect wheel lift and control actuators to maintain a predetermined angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a steering damper is used to avoid kickbacks, then the effects of kickback are damped, but kickbacks still occur in attenuated form
Solution Approach 1:
The control unit detects wheel lift-off conditions using sensor data (acceleration sensors, steering angle sensors) and proactively adjusts the steering angle before the front wheel can land in a harmful direction. This preliminary action prevents kickbacks rather than merely dampening their effects, by anticipating the harmful event and counteracting it before occurrence.
Solution Approach 2:
The system continuously monitors vehicle operating parameters through a sensor system (acceleration sensors, steering angle sensors) and uses this feedback to dynamically adjust the steering angle. The control unit compares current parameters with stored limiting values and modifies steering accordingly, creating a closed-loop control system that prevents kickbacks through real-time adaptation.
2Reliability
If a steering damper is used to prevent kickbacks, then safety is improved, but device complexity increases
Solution Approach 1:
The control unit performs multiple functions: it processes data from various sensors (acceleration, steering angle), determines wheel lift-off conditions, calculates appropriate steering angle adjustments, and controls the steering actuator. This multi-functional approach consolidates what would otherwise require separate dedicated systems into a single integrated control unit, reducing overall system complexity while maintaining high reliability.
Solution Approach 2:
The patent replaces traditional mechanical steering dampers with an electronically controlled steering assistance system. Instead of using passive mechanical damping elements, the system uses electronic sensors, control algorithms, and electric actuators to achieve kickback prevention. This substitution reduces mechanical complexity and allows for more precise, adaptive control.
3Reliability
If the steering device is aligned at a predetermined steering angle during wheel lift, then kickbacks are prevented, but the steering response time is reduced
Solution Approach 1:
The system detects wheel lift-off conditions using sensor data (acceleration sensors, steering angle sensors) and proactively adjusts the steering angle before the front wheel can land in a harmful direction. This preliminary action prevents kickbacks rather than merely dampening their effects, by anticipating the harmful event and counteracting it before occurrence.
Solution Approach 2:
The control unit continuously monitors vehicle operating parameters and maintains active control during the wheel lift-off phase. Rather than waiting for kickback to occur and then reacting, the system maintains continuous detection and control adjustment throughout the entire wheel lift duration, ensuring timely prevention without significant delay.

AI summary
A method for controlling a steering assistance system of a steering device of a single-track motor vehicle. Current vehicle operating parameters are continuously recorded by way of a sensor system; and, subsequently the current vehicle operating parameters are compared with limit values stored in a control unit of the single-track motor vehicle in order to determine a lifting front wheel of the single-track motor vehicle for the corresponding vehicle operating parameters by way of the control unit. Then, if at least one of the limit values is reached and/or exceeded, the steering assistance system is controlled by way of the control unit in such a way that the steering device is aligned to a predefined steering angle of the steering device, at which steering angle the steering device is prevented from wobbling.
