Autonomous Vehicle Passenger Verification Using GPS Rerouting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face challenges in confirming the identity of the assigned passenger upon pickup, as passengers may inadvertently enter the wrong vehicle, and existing verification methods are prone to errors, especially in crowded environments.
Innovation Solution
The system uses on-board computing devices to authenticate client computing devices through GPS coordinate comparison and communication with passenger devices, allowing real-time verification of the passenger's identity and adjusting the destination if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS coordinate comparison is used to verify passenger identity, then passenger identification accuracy is improved, but system complexity increases
Solution Approach 1:
The patent uses GPS coordinates as an intermediary to verify passenger identity. Instead of direct physical verification, the system compares the passenger's reported GPS location with the vehicle's current GPS location to determine if they match, thereby identifying the correct passenger without complex physical verification mechanisms
Solution Approach 2:
The patent replaces manual verification methods (visual identification, physical tickets, or human checking) with an automated electronic system that uses GPS coordinate comparison and digital communication between client devices and vehicle systems to verify passenger identity automatically
2Reliability
If real-time location monitoring is implemented to confirm passenger identity, then verification reliability is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic location monitoring rather than continuous monitoring. The vehicle's computing device receives location information from the client computing device at intervals and compares it with the vehicle's current location at corresponding times, reducing energy consumption while maintaining verification reliability
Solution Approach 2:
The passenger's client computing device automatically provides location information to the vehicle system without requiring active participation from the passenger. The device self-monitors and transmits its location data, eliminating the need for manual verification actions while maintaining reliable verification
3Reliability
If destination confirmation is performed before departure, then passenger safety is improved, but time consumption increases
Solution Approach 1:
The system performs destination confirmation as a preliminary action before the vehicle departs. The vehicle's computing device compares the destination location from the client device with the vehicle's assigned destination before beginning travel, ensuring the correct passenger is in the correct vehicle before time is lost to incorrect routing
Solution Approach 2:
The system implements feedback mechanisms where the vehicle's computing device receives destination information from the client device and compares it with assigned destination data. If the destinations match, the system confirms the correct passenger is boarded; if not, the vehicle can request correction before departure, providing safety verification without excessive time loss

AI summary
Aspects of the disclosure provide systems and methods for confirming the identity of a passenger and changing destination of a vehicle. This may include receiving dispatching instructions to pick up a first passenger at a pickup location and to drop off the first passenger at a first destination as well as authentication information for authenticating a first client computing device of the first passenger. Once the client device is authenticated and a second passenger enters the vehicle, the vehicle is maneuvered towards the first destination. While doing so, a location of the vehicle is compared to location information received from the client computing devices. A notification is sent to a dispatching server based on the comparison and a second destination location is received in response. The vehicle is then maneuvered towards the second destination instead of the first destination.
