Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack an effective method to early recognize the risk of aquaplaning, which can lead to unexpected loss of tire contact with the road, resulting in loss of steering and braking control, especially at high speeds.
Innovation Solution
A procedure and device that capture image data of the area around a vehicle's wheel, detect splash water, and classify the road state as dry, wet, or with aquaplaning risk, using the analysis of splash water patterns and characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spray water detection is used to classify road surface conditions, then early detection of aquaplaning risk is achieved, but device complexity increases due to additional image acquisition and evaluation components
Solution Approach 1:
The image acquisition device serves multiple functions: it captures images for spray water detection, can identify road surface conditions, and provides data for aquaplaning risk assessment. By making the image acquisition and evaluation system multi-functional, the patent avoids adding separate dedicated devices for each function, thereby improving reliability while limiting the increase in device complexity.
2Measurement precision
If image data of the area around the wheel is captured and analyzed, then spray water detection accuracy is improved, but loss of time increases due to image processing requirements
Solution Approach 1:
The system continuously captures images of the area around the wheel in advance, so that when spray water appears indicating aquaplaning risk, the evaluation can immediately analyze pre-captured image data rather than waiting for conditions to develop. This preliminary capture of image data enables faster response time while maintaining detection precision.
Solution Approach 2:
The evaluation device prioritizes real-time analysis of image data to quickly identify spray water patterns associated with aquaplaning risk, skipping less critical processing steps to deliver rapid results. This allows the system to maintain high measurement precision while minimizing the time loss associated with image processing.

AI summary
The present invention relates to a classification of road surface conditions based on the spray water occurring at a wheel of the vehicle. For this purpose, the space around a wheel of the vehicle is captured by a camera, and the image captured by the camera is analyzed to detect spray water. Based on the detected spray water, for example, the angle, direction, or throw distance of the spray water, a distinction can be made between a dry road surface, a wet road surface, or a road surface with a risk of aquaplaning.
