Roadside ODC Monitoring for Autonomous Vehicle Boundary Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The reliability of operational design condition (ODC) monitoring results in autonomous driving vehicles is insufficient, posing a safety threat when the ODC exceeds its running boundary.
Innovation Solution
A roadside device collects road environment information and determines ODC information of a first area, comparing it with the vehicle's preset ODC elements to assess whether the vehicle's ODC exceeds its running boundary, utilizing data from both the roadside device and the vehicle to enhance reliability and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle uses only its own sensors and preset ODC elements to monitor ODC, then the device complexity is low, but the reliability of ODC monitoring results is insufficient
Solution Approach 1:
The patent introduces a roadside device as an intermediary between the vehicle and the environment. This roadside device collects road environment information independently and provides it to the vehicle, acting as a mediator that enhances the vehicle's ODC monitoring capability without requiring the vehicle itself to have complex sensing systems for all environmental factors.
Solution Approach 2:
The patent merges the ODC monitoring functions of the vehicle and the roadside device into a collaborative system. The vehicle's preset ODC elements are combined with the roadside device's collected environment information to jointly determine whether the ODC exceeds the running boundary, thereby improving reliability through data fusion.
2Reliability
If the vehicle collects comprehensive ODC information itself, then the reliability of monitoring improves, but the use of energy and device complexity increase
Solution Approach 1:
The roadside device serves as an energy-efficient intermediary that performs environmental information collection independently. The vehicle can obtain reliable ODC information from the roadside device without expending energy on its own comprehensive sensing infrastructure, thus reducing the vehicle's energy consumption while maintaining monitoring reliability.
Solution Approach 2:
The roadside device provides self-service by autonomously collecting and processing road environment information, then making this information available to the vehicle. This eliminates the need for the vehicle to perform energy-intensive environmental sensing tasks itself.
3Ease of operation
If the vehicle uses limited preset ODC elements, then the ease of operation is high, but the ability to recognize ODC objects beyond preset elements is insufficient
Solution Approach 1:
The roadside device acts as an intermediary that supplements the vehicle's limited preset ODC elements with comprehensive environment information. This allows the system to maintain the simplicity of preset elements while gaining the adaptability to recognize a broader range of ODC objects through the roadside device's data.
Solution Approach 2:
The roadside device provides universal environmental information that can serve multiple ODC recognition needs. Instead of requiring the vehicle to have specialized sensors for each type of ODC object, the roadside device's comprehensive monitoring provides multi-functional support for recognizing various ODC objects.

AI summary
A monitoring method, apparatus, and system are provided. The method may be applied to the field of intelligent driving. The method includes: determining operational design condition ODC information of an area, where the ODC information indicates an ODC object and a status of the ODC object (S801); obtaining a preset ODC element of a vehicle (S802); and determining, based on the ODC information of the area and the preset ODC element, whether an ODC of the vehicle exceeds a running boundary (S803). The provided monitoring method may be applied to a new energy vehicle or an intelligent vehicle. This helps improve reliability of a result of determining whether the ODC of the vehicle exceeds the running boundary, to help ensure vehicle safety. In addition, an ODC object or a status of an ODC object that makes the ODC of the vehicle exceed the running boundary can be further determined, to help assist the vehicle in updating the preset ODC element.
