Vehicle V2V Communication for Road Surface Abnormality Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-to-vehicle communication systems lack the ability to effectively detect and mitigate road surface abnormalities, such as icy or slippery conditions, which can lead to accidents as following vehicles may also encounter similar conditions without adequate avoidance measures.
Innovation Solution
A vehicle-to-vehicle communication system that includes a road-surface abnormality determiner and driving controller, which compares reference driving information with actual driving information to detect abnormalities and sends instructions to following vehicles to adjust their wheel driving forces to avoid the issue, allowing them to change route and avoid the abnormality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If vehicle-to-vehicle communication is implemented without road surface abnormality detection, then communication capability is improved, but safety against road surface abnormalities remains insufficient
Solution Approach 1:
The leading vehicle detects road surface abnormalities in advance and communicates this information to the following vehicle before the following vehicle encounters the abnormality. This preliminary detection and communication allows the following vehicle to prepare avoidance maneuvers, transforming reactive response into proactive safety measures.
Solution Approach 2:
The system establishes a feedback loop where the leading vehicle's detection results are communicated to the following vehicle, which then adjusts its driving behavior accordingly. This feedback mechanism enables continuous adaptation to road surface conditions, improving overall system reliability and safety.
2Reliability
If the leading vehicle communicates abnormality information to the following vehicle, then safety is improved, but communication complexity increases
Solution Approach 1:
The road surface abnormality detection and communication functions are extracted as separate, dedicated modules within the vehicle's control system. By isolating these specific functions from the overall vehicle control architecture, the system achieves improved safety without proportionally increasing overall system complexity.
Solution Approach 2:
The communication system is designed to handle multiple types of vehicle-to-vehicle information exchange, not just road surface abnormality data. By creating a universal communication framework that can transmit various types of driving information, the system reduces the need for specialized communication channels for each function, thereby managing complexity.
3Ease of operation
If the following vehicle adjusts wheel driving forces to avoid abnormalities, then avoidance capability is improved, but control complexity increases
Solution Approach 1:
The following vehicle's control system automatically adjusts wheel driving forces based on received abnormality information without requiring manual driver intervention. The system serves itself by autonomously interpreting the communicated data and executing appropriate avoidance maneuvers, improving ease of operation while keeping the control logic contained within standard vehicle control parameters.

AI summary
A vehicle includes a communicator, a road-surface abnormality determiner, and a driving controller. The communicator is configured to establish communication with a following vehicle following the vehicle driving ahead in a travel road. The road-surface abnormality determiner is configured to determine whether there is an abnormality on a road surface of the travel road, based on comparison between first driving information, serving as a reference to be used when the vehicle drives on the travel road, and second driving information detected as a result of the vehicle having actually driven. When the road-surface abnormality determiner determines that there is the abnormality, the driving controller is configured to predict whether the following vehicle is able to avoid the abnormality and to send an instruction to avoid the abnormality to the following vehicle via the communicator if the driving controller predicts that the following vehicle is able to avoid the abnormality.
