Two-Wheeler Assistance Control Using Rider Reaction Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-wheeler assistance systems often intervene in ways that contradict the rider's expectations, lacking adaptability to the driver's reaction and situational awareness.
Innovation Solution
An assistance system that adjusts its interventions based on the driver's reaction and tolerance values, using captured driving dynamics parameters and upcoming situation assessments to determine a hazard level, activating or suppressing assistance systems accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the assistance system continuously monitors and intervenes based on detected hazards, then safety is improved, but the system may intervene contrary to the driver's expectations
Solution Approach 1:
The system monitors driver interventions (braking, acceleration, steering) and uses this feedback to adjust the hazard level assessment. When the driver actively intervenes to change vehicle dynamics, the system detects this and modifies the hazard evaluation accordingly, ensuring future interventions align with the driver's intentions and expectations.
Solution Approach 2:
The hazard level is not fixed but dynamically adjusted based on real-time driver behavior. The system continuously adapts the hazard assessment by incorporating detected driver interventions, making the safety system flexible and responsive to the driver's changing intentions rather than following a rigid intervention protocol.
2Measurement precision
If the assistance system uses multiple detection devices and evaluation steps, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The evaluation unit serves multiple functions: it detects driving dynamics parameters, assesses upcoming driving situations, determines hazard levels, and monitors driver interventions. By consolidating these functions into a single multi-functional evaluation unit, the system achieves high measurement precision without proportionally increasing device complexity.
Solution Approach 2:
The system combines multiple detection devices (for vehicle dynamics, environment, and driver behavior) into an integrated assessment process. The evaluation unit merges data from various sensors and processes them together to determine the hazard level, reducing overall system complexity while maintaining comprehensive monitoring capabilities.

AI summary
The invention comprises a method for controlling an assistance system of a two-wheeler, an assistance system and a two-wheeler, and a computer program. The method comprises the steps of acquiring at least one driving dynamics parameter of the two-wheeler and acquiring an upcoming driving situation. The method further comprises assigning the upcoming driving situation, depending on the at least one driving dynamics parameter, to a first value of a hazard level, and acquiring a change in the at least one driving dynamics parameter due to driver intervention. It comprises assigning the change in the at least one driving dynamics parameter to a tolerance value, and determining a second value of the hazard level, wherein the second value is the difference between the first value and the tolerance value.The procedure includes activating the assistance system if the second value is greater than an intervention limit, or suppressing the assistance system if the second value is less than the intervention limit.
