Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assistance systems are inadequate for supporting single-track motor vehicle drivers in safely navigating curves, as they fail to effectively assess and mitigate the risk of falling.
Innovation Solution
A method that compares current driving conditions and driver-specific dynamics with impending situations, using sensors and navigation data to output warning signals when danger thresholds are reached, incorporating past leaning positions, brake pressures, and traffic density to minimize the risk of falling.

Engineering Contradiction Analysis
1Reliability
If driver assistance systems provide comprehensive monitoring and warning functions, then safety in curve negotiation is improved, but system complexity increases
Solution Approach 1:
The driver assistance system is segmented into multiple independent functional modules: a sensor unit for detecting driving parameters, a navigation unit for acquiring curve information, a computer for processing and evaluating data, and a signaling device for warning the driver. This modular segmentation allows each component to perform its specific function independently, improving overall system reliability while managing complexity through functional separation.
Solution Approach 2:
The system performs preliminary actions by continuously monitoring current driving parameters and comparing them with upcoming curve requirements before the dangerous situation occurs. The computer evaluates whether current driving behavior is appropriate for the impending curve and issues warnings in advance, allowing the driver to correct their behavior before losing control or falling.
2Reliability
If the system continuously monitors and warns the driver, then the risk of falling is reduced, but information processing requirements increase
Solution Approach 1:
The system extracts only the essential and relevant information from the vast amount of available data. The computer specifically evaluates current driving parameters (speed, inclination, acceleration) in relation to upcoming curve characteristics (radius, inclination) and only processes information that is directly relevant to curve negotiation safety. This selective extraction reduces information processing load while maintaining effective risk assessment.
Solution Approach 2:
The system implements continuous feedback by comparing current driving behavior with required behavior for upcoming curves. The computer constantly monitors driving parameters and provides feedback through warning signals when deviations from safe driving patterns are detected, enabling the driver to adjust their behavior in real-time based on systematic evaluation of the relationship between current state and impending requirements.

AI summary
The invention relates to a method for assisting a driver of a single-track motor vehicle during a drive in order to drive through a curve safely. In the method, at least one current driving state variable (1) and driver-specific driving dynamics variables (2) are compared with an approaching driving situation (3) and, if a danger threshold value is reached or exceeded, a warning signal (4) is output. The current speed of the motor vehicle is sensed by means of a speed sensor (11) and transmitted to a computer-and-memory unit (5) as the current driving state variable. Both previously reached inclined positions of the single-track motor vehicle and previously reached brake pressures and/or brake pressure gradients are stored by the computer-and-memory unit (5) as the driver-specific driving dynamics variables (2). Furthermore, in order to evaluating the approaching driving situation, a curve radius of a curve to be driven through next is determined by means of a navigation unit (31) and is transmitted to the computer-and-memory unit (5). The invention further relates to a driver assistance system for performing the method and to a single-track motor vehicle having the driver assistance system.
