Autonomous Vehicle Pickup Routing for Moving Rider Rendezvous
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current self-driving vehicle systems face challenges in efficiently adapting to changing rider locations and movement speeds, leading to suboptimal pick-up routes that may result in delayed rendezvous or increased travel time.
Innovation Solution
A vehicle management system that utilizes a location tracking system and communication system to monitor rider locations and movement speeds, allowing for real-time adjustments to pick-up routes by suggesting alternative locations closer to the rider's current position, thereby optimizing the rendezvous process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the vehicle navigation system directs the vehicle to the originally scheduled pick-up location, then the vehicle follows its initial route plan, but the rendezvous time may be delayed if the rider has moved to a different location
Solution Approach 1:
The system continuously receives real-time location data from the rider's mobile device and compares it with the scheduled pick-up location. When a location mismatch is detected, the system automatically updates the navigation route to the rider's current location, ensuring timely rendezvous without manual intervention
Solution Approach 2:
The pick-up location is transformed from a static predetermined coordinate to a dynamic target that automatically updates based on the rider's real-time location. The navigation system continuously adjusts the route to maintain optimal rendezvous timing
2Productivity
If the vehicle continuously monitors and updates the pick-up location based on rider movement, then the rendezvous efficiency is improved, but the system complexity increases
Solution Approach 1:
The rider's mobile device serves as an intermediary that provides location data to the vehicle's navigation system. This eliminates the need for complex onboard tracking equipment in the vehicle, as the rider's device already contains the necessary GPS functionality
Solution Approach 2:
The rider's mobile device automatically performs location tracking and transmission without requiring additional specialized equipment. The system leverages the rider's existing smartphone capabilities to provide the necessary location data
3Ease of operation
If the vehicle uses a fixed pick-up location, then the navigation system is simpler to operate, but the travel time increases when the rider moves to a different location
Solution Approach 1:
The system establishes a scheduled pick-up location in advance, providing a default target for the navigation system. This preliminary setting simplifies initial operation while the system retains the capability to automatically update the location when needed
Solution Approach 2:
The pick-up location parameter transitions from a fixed predetermined value to a dynamically changing value based on rider movement. The system automatically detects and implements parameter changes without requiring complex user input or reconfiguration
Data Source
AI summary
A vehicle management system can send a first pick-up location to a vehicle navigation system and to a remote computing device of a rider. The remote computing device can include an accelerometer that monitors accelerations as the rider carries the remote computing device. Analyzing the accelerations enables the vehicle management system to choose or update a pick-up location to best serve the rider.
