Abstract
A road condition is classified based on spray water occurring at a wheel of the vehicle. To this end, the space around a wheel of the vehicle is imaged by a camera and the image captured by the camera is analyzed to detect spray water therein. A distinction can be made between a dry road, a wet road or a road having a risk of aquaplaning on the basis of the detected spray water, e.g. based on the angle, direction or projection range of the spray water.
Claims12
A method of determining a road condition, comprising the steps:
- providing (S1) image data by an image capturing device (11), wherein the image capturing device (11) captures at least a part of a space around a wheel of a vehicle (1);
- detecting (S2) spray water in the provided image data;
- and
- classifying (S3) a road condition using the detected spray water in the provided image data;
- wherein the classifying of the road condition includes making at least one distinction between a dry road, a wet road and a road having a risk of aquaplaning.
2 more elements
An apparatus for determining a road condition, comprising:
- an image capturing device (11) configured to capture and provide image data of at least a part of a space around a wheel (21) of a vehicle (1);
- and
- an evaluation device (12) configured to detect spray water in the provided image data and to classify a road condition using the spray water detected in the image data,
- wherein the classifying of the road condition includes making at least one distinction between a dry road, a wet road and a road having a risk of aquaplaning.
