Last Mile Navigation Cache for Parked Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle navigation systems typically clear destination information from memory after arrival, leaving users without guidance for the last mile navigation from a parked location to the actual destination, especially when parking is unavailable or inconvenient.
Innovation Solution
The system determines vehicle arrival and parking, then transmits last mile navigation information to a mobile device, providing routes and instructions for the user to reach the destination on foot or via other means from the parked location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the vehicle navigation system clears destination information from memory after arrival, then the system memory is freed for new destinations, but the user loses navigation guidance for the last mile from parked location to destination
Solution Approach 1:
The navigation system divides the navigation process into two distinct segments: vehicle navigation to destination and pedestrian navigation from parked location to destination. The system clears memory after vehicle arrival but provides a separate pedestrian navigation mode that can be activated by the user, thereby freeing memory while still offering last-mile guidance when needed.
Solution Approach 2:
The system introduces an intermediary mechanism - a user-activatable pedestrian navigation mode - that bridges the gap between clearing memory and providing continued guidance. This intermediary allows users to obtain last-mile directions without permanently retaining destination data in system memory, using temporary data transmission to mobile devices or displays.
2Loss of information
If the vehicle navigation system provides continuous destination information in memory, then the user always has navigation guidance available, but the system cannot efficiently manage memory for multiple destinations
Solution Approach 1:
The system performs preliminary actions by transmitting destination information to the user's mobile device or display system before clearing memory. This preliminary transfer ensures navigation guidance is preserved in the user's possession while allowing the system to efficiently manage memory for subsequent destinations without continuous retention overhead.
3Ease of operation
If parking is unavailable at the destination, then the user must park at a distant location, but the user lacks directional guidance for the final approach to the destination
Solution Approach 1:
The system dynamically adapts the navigation mode based on the user's situation. When parking is unavailable or the user parks remotely, the system transitions from vehicle-centered navigation to pedestrian-centered navigation, providing real-time directional guidance for the last mile. This dynamic adaptation ensures continuous ease of operation regardless of parking conditions.

AI summary
Disclosed are methods, systems, and computer-readable mediums for providing last mile navigation. In an example, the system may determine that a vehicle has arrived at or near the destination. The system may store the destination in memory when determined that the vehicle has arrived at or near the destination. The system may monitor the location of the vehicle and determine the vehicle is parked at a parked location. Once determined that the vehicle is parked, the system may transmit last mile navigation information associated with the destination and the parked location to a mobile device.
