Dynamic Pick-up Location Adjustment for Self-driving Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current self-driving vehicle systems face challenges in efficiently adapting to changing rider locations and movement patterns, leading to potential delays and inefficiencies in pick-up routes, which can impact safety and convenience.
Innovation Solution
A vehicle management system that utilizes a location tracking system and communication protocols to monitor rider locations and movement speeds, allowing for real-time adjustments in pick-up locations and routes to optimize rendezvous times and reduce delays, by prompting riders and vehicles to change routes if a closer or more suitable pick-up location is identified.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle navigation system directs the vehicle to a fixed pick-up location, then the route planning is simple and deterministic, but the system cannot adapt to rider movement or changing conditions, leading to delays
Solution Approach 1:
The pick-up location is transformed from a static fixed point to a dynamic target that automatically adjusts based on the rider's real-time location and movement speed. The system continuously updates the optimal pick-up location by calculating the rider's projected position forward in time, ensuring the vehicle always heads toward where the rider will be rather than where they are now. This dynamic approach resolves the contradiction by enabling adaptability without requiring complex manual intervention.
Solution Approach 2:
The system implements continuous feedback loops by monitoring the rider's location and movement speed, then using this information to recalculate and update the optimal pick-up location. The vehicle navigation system receives ongoing location data from the location tracking system and adjusts its route accordingly. This feedback mechanism allows the system to adapt to changing conditions automatically, resolving the contradiction between adaptability and complexity.
2Loss of time
If the vehicle waits for the rider at the original pick-up location, then the rendezvous point remains fixed and easy to coordinate, but delays occur when the rider is moving quickly or changing direction
Solution Approach 1:
The system performs preliminary calculation of the rider's future position by projecting their current movement trajectory forward in time. Instead of reacting to the rider's current location, the system anticipates where the rider will be at the estimated arrival time and sets that as the pick-up location. This preliminary action eliminates waiting time and ensures the vehicle arrives at the correct location simultaneously with the rider, resolving the contradiction between minimizing time loss and tracking difficulty.
Solution Approach 2:
The location tracking system on the rider's device automatically provides location and movement data without requiring manual input or intervention. The system uses the rider's smartphone or wearable device to continuously monitor position and calculate movement speed, then feeds this information back to the vehicle navigation system. This self-service approach minimizes the difficulty of tracking while enabling real-time adaptation to reduce rendezvous time.
3Productivity
If the vehicle changes pick-up location dynamically, then rendezvous efficiency improves, but communication with the rider becomes more complex to ensure they know where to meet
Solution Approach 1:
The communication system acts as an intermediary by automatically transmitting the updated pick-up location information from the vehicle management system to the rider's device. Rather than requiring complex two-way negotiation or manual coordination, the system unilaterally determines the optimal location and communicates it to the rider through the existing communication interface. This intermediary approach maintains simplicity while enabling dynamic location changes to improve pick-up efficiency.
Solution Approach 2:
The rider's device automatically receives and displays the updated pick-up location without requiring the rider to actively query or confirm changes. The communication system pushes location updates to the rider's smartphone or wearable device, which then presents the information through the existing user interface. This self-service communication approach maintains simplicity while enabling efficient dynamic location adjustments.

AI summary
A vehicle management system can send a first pick-up location to a remote computing device of a prospective rider. A location tracking system is configured to monitor a location of the rider as the rider walks to rendezvous with the vehicle. The vehicle management system can later determine, based on the location of the rider as the rider walks to rendezvous with the vehicle, that the vehicle could rendezvous with the rider sooner by using a second pick-up location. The vehicle management system can prompt the vehicle navigation system to cease directing the vehicle toward the first pick-up location and instead direct the vehicle toward the second pick-up location. The vehicle management system can prompt the remote computing device to cease directing the rider toward the first pick-up location and instead direct the rider toward the second pick-up location.
