Vehicle Assist Control Based on V2V Information Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face challenges in reliably receiving and processing another-vehicle information due to potential communication interruptions and varying reliability between vehicle-to-vehicle and server-based communication methods, which can affect the accuracy and timing of collision avoidance and driver notifications.
Innovation Solution
A vehicle information processing system that selectively performs driving assist control based on direct vehicle-to-vehicle communication for high reliability and switches to notification control when relying on server communication for lower reliability, ensuring accurate and timely vehicle control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle receives another-vehicle information from a server apparatus, then the notification control can be performed, but the driving assist control cannot be performed due to lower reliability
Solution Approach 1:
The system dynamically adjusts the level of automation based on communication reliability. When direct vehicle-to-vehicle communication is detected, full driving assist control is enabled. When only server-mediated communication is available, the system transitions to notification-only mode, adapting the control strategy to match the reliability of the information source.
Solution Approach 2:
The system changes the operational parameter of automation level based on the information source. High-reliability direct communication enables automated driving assist control, while lower-reliability server communication triggers a parameter change to manual notification-only mode, ensuring safety while maintaining system responsiveness.
2Reliability
If the vehicle performs driving assist control based on another-vehicle information, then the vehicle safety is improved, but the risk of unsafe automatic control increases when information reliability is low
Solution Approach 1:
The system uses the communication method itself as an intermediary indicator of reliability. Direct vehicle-to-vehicle communication serves as a trusted intermediary that validates the authenticity of another-vehicle information, enabling safe automated control. Server-mediated communication lacks this direct intermediary validation, triggering notification-only mode to prevent unsafe automatic control.
3Reliability
If the vehicle uses vehicle-to-vehicle communication, then the another-vehicle information reliability is high, but the communication may be temporarily interrupted
Solution Approach 1:
The system implements partial automation based on information reliability. When direct vehicle-to-vehicle communication is available, full driving assist control is activated. When communication is interrupted or only server communication remains, the system reduces to notification-only mode, applying partial action appropriate to the current reliability level rather than maintaining full automation.
Data Source
AI summary
An information processing apparatus mounted on a vehicle includes a controller configured to be capable of performing driving assist control and notification control. In a case where the vehicle receives another-vehicle information including information about a travel state of another vehicle from another vehicle by vehicle-to-vehicle communication, the controller performs the driving assist control based on the another-vehicle information. Furthermore, in a case where the vehicle receives the another-vehicle information not by vehicle-to-vehicle communication but from a server apparatus that performs communication with another vehicle, the controller performs the notification control based on the another-vehicle information without performing the driving assist control based on the another-vehicle information.
