Multi-modal Navigation System with In-vehicle to Mobile Handoff
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems lack the ability to seamlessly hand off turn-by-turn directions between in-vehicle navigation systems and mobile devices for multi-modal trips that include both driving and pedestrian routes, requiring users to manage separate navigation instructions on different devices.
Innovation Solution
A system that allows an in-vehicle navigation system to provide turn-by-turn driving instructions and simultaneously transfer data to a mobile device for turn-by-turn pedestrian navigation, enabling planning and execution of multi-modal trips with integrated driving and pedestrian route guidance on relevant devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If navigation instructions are provided separately on different devices for driving and pedestrian routes, then each device can provide specialized navigation, but users must manage multiple navigation systems independently increasing complexity
Solution Approach 1:
The patent combines driving route navigation and pedestrian route navigation into a single integrated navigation system. The system receives a destination input and automatically determines a multi-modal route that includes both driving and pedestrian segments, providing unified turn-by-turn instructions across both modes of travel through one device interface.
Solution Approach 2:
The navigation system is designed to perform multiple functions: it can provide driving directions, pedestrian directions, and seamlessly transition between modes. The system determines multi-modal routes that include both driving routes to a driving destination and pedestrian routes from the driving destination to the final pedestrian destination, making a single device universally capable of handling all navigation needs.
2Ease of operation
If users manage separate navigation instructions on different devices, then device specialization is maintained, but time is lost in switching between navigation systems
Solution Approach 1:
The system performs preliminary route planning that encompasses the entire multi-modal journey before the user begins travel. It determines the complete multi-modal route including both driving and pedestrian segments in advance, so that when the user needs to switch from driving to pedestrian navigation, the pedestrian route is already calculated and ready for immediate display without requiring separate device access or real-time route calculation.
3Device complexity
If integrated multi-modal route planning is implemented on one device, then navigation complexity is reduced, but the system must process and transfer data between different navigation modes
Solution Approach 1:
The navigation system automatically determines the multi-modal route without requiring user intervention to switch between driving and pedestrian directions. When the user inputs a destination, the system autonomously calculates the complete route including driving segments to a driving destination and subsequent pedestrian segments to the final destination, automatically providing turn-by-turn instructions for each mode without manual device switching or additional user input.

AI summary
A multi-modal navigation system for a vehicle is disclosed. The navigation system is configured to determine a multi-modal route including a driving route to a driving destination and a pedestrian route to a pedestrian destination from the driving destination. Turn-by-turn driving navigation for the driving route is provided, and data for the pedestrian route is provided to a mobile device such that turn-by-turn pedestrian navigation for the pedestrian route is enabled via the mobile device.
