Autonomous Vehicle Control in Restricted Areas Without Direct Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face challenges in navigating restricted areas while ensuring security and privacy concerns are met, as existing systems struggle to balance sensing capabilities with security protocols.
Innovation Solution
The system dynamically shares automated driving functionality between the autonomous vehicle and the infrastructure of the restricted area, with the infrastructure taking over certain autonomous driving functions and providing replacement sensor information to ensure compliance with security levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the autonomous vehicle uses its own sensors and autonomous driving system to navigate, then the vehicle can operate autonomously with full sensing capabilities, but sensitive information about the restricted area may be recorded or disclosed
Solution Approach 1:
The patent extracts the sensing and navigation functions from the autonomous vehicle and transfers them to the infrastructure system within the restricted area. The vehicle's sensors are disabled or masked, and only infrastructure-provided sensor data is used for navigation decisions, preventing the vehicle from recording sensitive area information while maintaining autonomous navigation capability
Solution Approach 2:
The infrastructure system acts as an intermediary between the autonomous vehicle and the physical environment. It provides replacement sensor information to the vehicle, mediating the interaction so the vehicle can navigate without directly sensing restricted area details, thus eliminating the security risk while preserving automation
2Object-affected harmful factors
If the infrastructure provides replacement sensor information to the autonomous vehicle, then security and privacy are protected, but the vehicle loses direct sensing capabilities
Solution Approach 1:
The infrastructure system creates copies of sensor data (visual, auditory, environmental information) and provides these copies to the autonomous vehicle instead of allowing direct access to the real sensors. This copying mechanism preserves the vehicle's navigation functionality while preventing it from recording actual restricted area information, as it operates on replicated data
3Object-affected harmful factors
If the autonomous vehicle disables its sensors in restricted areas, then security protocols are followed, but the vehicle cannot independently navigate
Solution Approach 1:
The patent merges the navigation control functions with the infrastructure system. When sensors are disabled, the infrastructure provides both the sensor data and the navigation decisions, combining environmental monitoring and path planning into a unified infrastructure-controlled system that maintains ease of operation without independent vehicle autonomy

AI summary
Various systems and methods for providing autonomous driving within a restricted area are discussed. In an examples, an autonomous vehicle control system can include an interface for receiving data from multiple sensors for detecting an environment about the vehicle, a security processor coupled to the configured to receive sensor information from the sensor interface, and autonomous driving system including one or more virtual machines configured to selectively receive information from the security processor based on a security request from infrastructure of the restricted area.
