Autonomous Vehicle Routing for Restricted Object Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles do not consider whether prohibited or restricted objects are present in the vehicle during route planning, potentially leading to unauthorized travel through restricted areas.
Innovation Solution
An autonomous vehicle system that detects restricted objects using an input signal, defines a conditional route to avoid restricted areas, and provides notifications to passengers or authorities as necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the AV uses a standard navigation system that does not detect restricted objects, then the routing system is simple and fast, but the AV may travel through restricted geographical areas with prohibited objects
Solution Approach 1:
The system performs preliminary detection of restricted objects in the vehicle before finalizing the travel route. The processor detects the presence of restricted objects and then determines the route accordingly, preventing compliance issues before they occur rather than reacting to them during travel
Solution Approach 2:
The patent introduces an intermediary detection system that acts as a bridge between the vehicle's cargo and the navigation system. This intermediary component detects restricted objects and translates that information into routing decisions, allowing the standard navigation system to function while adding compliance capabilities
2Reliability
If the AV defines multiple conditional routes based on restricted objects, then compliance with restrictions is improved, but the routing calculation time and computational load increase
Solution Approach 1:
The system pre-determines multiple potential routes including conditional routes that account for various restricted objects before the actual travel begins. When a restricted object is detected, the system already has pre-calculated alternative routes ready for immediate selection, avoiding time-consuming real-time calculations
Solution Approach 2:
The routing system dynamically adapts between different route configurations based on detected restricted objects. The processor can switch between standard routes and conditional routes in real-time based on the presence or absence of restricted objects, optimizing both compliance and efficiency
3Loss of information
If the AV provides detailed notifications about restricted areas and objects, then passenger awareness and compliance are improved, but the information processing and communication complexity increase
Solution Approach 1:
The notification system provides targeted information specifically about restricted areas and objects relevant to the current situation. Rather than providing generic or excessive information, the system tailors notifications to the specific restricted objects detected and the specific geographical areas the vehicle will traverse
Solution Approach 2:
The system implements a feedback loop where notifications are provided to passengers about restricted objects and areas, and the system monitors whether the detected restricted objects are actually present in the vehicle. This feedback mechanism ensures accurate information communication without requiring complex continuous monitoring systems

AI summary
A method includes defining an original travel route for an autonomous vehicle (AV) to a desired destination, detecting a restricted object in the AV based on an input signal employed to identify an object, defining a conditional route to the desired destination through one or more geographical areas permitting the restricted object using one or more route-object conditions in response to detecting the restricted object, and causing the AV to travel to the desired destination via the conditional route in response to detecting the object as the restricted object or via the original travel route in response to not detecting the object as the restricted object.
