Multimodal Vehicle Route Planning with Small Vehicle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing route planning methods for motor vehicles lack flexibility and efficiency, particularly in multimodal transportation scenarios, where the presence of a small vehicle being carried is not adequately accounted for, leading to suboptimal route planning that may not minimize time, emissions, and costs effectively.
Innovation Solution
A method and apparatus for automatic route planning that detects the presence of a small vehicle being carried in a main motor vehicle and adapts the route to include a multimodal plan, optimizing the route sections for both vehicles and determining a transfer point based on predefined criteria, allowing for automatic replanning and updating during the journey.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional monomodal route planning is used for motor vehicles, then the routing process is simple, but it lacks flexibility and cannot optimize for multimodal transportation scenarios
Solution Approach 1:
The route planning system dynamically adapts its mode based on detected conditions. The navigation apparatus automatically switches between monomodal and multimodal planning approaches depending on whether a small vehicle is detected, allowing the system to remain simple when unnecessary while becoming flexible when needed.
Solution Approach 2:
The system automatically detects the presence of a small vehicle and autonomously determines whether to apply multimodal route planning without requiring manual user input. This self-service approach resolves the contradiction by enabling adaptability through automatic condition assessment rather than complex user-configurable settings.
2Productivity
If multimodal route planning is always applied, then route optimization for time and emissions is improved, but the system complexity and processing requirements increase
Solution Approach 1:
The system applies the more complex multimodal route planning methodology only partially - specifically when a small vehicle is detected. When no small vehicle is present, the system uses simpler monomodal planning, thus achieving optimization benefits only when necessary while avoiding unnecessary complexity in other scenarios.
3Adaptability or versatility
If automatic detection of small vehicle presence is implemented, then route planning adaptability is improved, but the detection system complexity increases
Solution Approach 1:
The system uses an intermediary detection apparatus that indirectly detects the presence of a small vehicle through signals or sensors rather than requiring direct observation or complex image analysis. This intermediary approach enables adaptability while keeping the detection complexity manageable by relying on existing vehicle sensor infrastructure.

AI summary
A method for automatic route planning includes recording a navigation destination using a navigation apparatus of a main motor vehicle, wherein the navigation apparatus configured for route planning. The method further includes detecting automatically whether the main motor vehicle is carrying a small vehicle. If so, then a multimodal route to the navigation destination is automatically planned using the navigation apparatus. The multimodal route includes a first route section that is to be traversed using the main motor vehicle, and a second route section that substantially adjoins the first route section at a transfer point, that leads to the navigation destination, and is to be traversed using the small vehicle.
