Motorcycle Curve Guidance System for Safe Trajectory Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motorcycle drivers face challenges in safely navigating corners due to the lack of advanced driver assistance systems, which are commonly available for passenger cars but not for two-wheelers, leading to risks of deviating from the lane and potentially entering oncoming traffic.
Innovation Solution
A method that uses a navigation system and camera system equipped on motorcycles to determine the topological properties of upcoming curves and the motorcycle's position within its lane, providing directional guidance via visual or auditory cues to ensure safe cornering, including determining the optimal driving trajectory, transverse position, and control inputs such as braking, coasting, or accelerating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver assistance systems with cameras and lane detection are implemented for motorcycles, then cornering safety is improved, but device complexity increases
Solution Approach 1:
The system combines multiple functions into a single integrated driver assistance system that performs lane detection, curve prediction, position determination, and directional guidance simultaneously, reducing overall system complexity while improving cornering safety
Solution Approach 2:
The system determines topological properties of curves and calculates optimal trajectories in advance before the motorcycle reaches the curve, allowing the driver to be informed early about the required positioning and direction changes, thereby improving safety without requiring complex real-time control mechanisms
2Measurement precision
If real-time position determination and trajectory calculation are performed, then guidance accuracy is improved, but computational requirements and processing time increase
Solution Approach 1:
The system calculates the optimal driving trajectory and determines the required directional guidance in advance based on predicted curve topology and current position, rather than computing complex trajectories in real-time during cornering, thus maintaining high accuracy while reducing processing time
Solution Approach 2:
The system uses an intermediate information display that translates complex trajectory calculations into simple directional indicators for the driver, reducing the computational burden while maintaining guidance accuracy through pre-calculated reference trajectories

AI summary
The invention relates to a method and a device for assisting the rider of a bicycle when approaching bends, in which on the basis of a navigation system the topology of a bend located in front of the bicycle in the direction of travel is determined, a travel trajectory which is suitable for reliably travelling through the bend is determined, the position of the bicycle within its own lane is determined and the direction in which the driver must direct the bicycle in order to arrive at the determined travel trajectory is communicated to the driver via information means.
