Cooperative ADAS V2X Guidance for Driving Error Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle-to-everything (V2X) communication systems are ineffective in preventing decision failures and movement errors, which are common among both human-driven and autonomous vehicles, leading to potential accidents and hindering the adoption of autonomous vehicles.
Innovation Solution
Implementing a cooperative safety system that uses V2X communications to identify and correct driving and movement errors by transmitting guidance messages between vehicles and non-vehicle road-users, allowing for improved decision-making and risk reduction through shared sensor data and guidance messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If V2X communication is used to prevent sensing failures, then information sharing between road-users is improved, but decision failures cannot be prevented
Solution Approach 1:
The patent combines multiple vehicles' sensor data and decision-making capabilities into a cooperative system. By merging the sensing resources of multiple road-users, the system creates a collective awareness that enables decision support beyond what any single vehicle can achieve independently.
Solution Approach 2:
The system implements feedback loops where vehicles share their sensor detections and decision states through V2X communication. This feedback mechanism allows road-users to verify decisions against others' observations and provides corrective information when decision errors are detected, continuously improving decision reliability.
2Reliability
If very high computing power is used inside a vehicle to prevent driving errors, then decision failure prevention is improved, but cost and complexity increase
Solution Approach 1:
The patent creates a universal decision support system that serves multiple vehicles simultaneously through V2X communication. Instead of each vehicle needing independent high-power computing for all decision scenarios, the system distributes computational tasks across the network, allowing simpler onboard computers to benefit from collective intelligence.
Solution Approach 2:
The system introduces V2X communication infrastructure as an intermediary that facilitates decision support without requiring extreme onboard computing power. The communication network acts as a mediator that shares computational burden and provides decision assistance to vehicles with modest processing capabilities.
3Extent of automation
If each AV uses its own decision algorithm, then vehicle autonomy is maintained, but cooperative decision-making is limited
Solution Approach 1:
The patent implements a dynamic decision-making architecture where vehicles can switch between independent and cooperative modes based on situational needs. The system adapts its level of cooperation dynamically, maintaining autonomy when operating independently while enabling collaborative decision-making when V2X communication and multiple road-users are available.

AI summary
Cooperative advanced driving assistance systems (ADAS) and cooperative safety systems using vehicle-to-everything (V2X) communications and methods of use. A method may comprise, by a guiding vehicle, periodically identifying an error of a nearby connected road-user and if an error is identified, transmitting a guidance message with guidance data using V2X communications to the connected road-user; and by the connected road-user as a guided road-user, using the guidance data to fix the error.
