Abstract
A fog detecting system for a vehicle includes a camera disposed at a vehicle and having a field of view forward of the vehicle, and a non-imaging sensor disposed at the vehicle and having a field of sensing forward of the vehicle. The camera captures image data and the non-imaging sensor captures sensor data. A control includes at least one data processor operable to process image data captured by the camera and sensor data captured by the non-imaging sensor. The control, responsive to processing of image data captured by the camera and processing of sensor data captured by the non-imaging sensor, determines presence of fog ahead of the vehicle and in the field of view of the camera and in the field of sensing of the non-imaging sensor.
Claims20
A fog detecting system for a vehicle, said fog detecting system comprising:
- a camera disposed at a vehicle and having a field of view forward of the vehicle, said camera capturing image data;
- a non-imaging sensor disposed at the vehicle and having a field of sensing forward of the vehicle, said non-imaging sensor capturing sensor data;
- a control comprising at least one data processor operable to process image data captured by said camera and sensor data captured by said non-imaging sensor;
- wherein said control, responsive to processing at said at least one data processor of image data captured by said camera, determines presence of an object in the field of view of the camera;
- wherein, responsive to the determination of the presence of the object via processing at said at least one data processor of image data captured by said camera, said control determines, via processing at said at least one data processor of sensor data captured by said non-imaging sensor, distance to the determined object;
- and
- wherein said control, responsive to the determined distance being less than a threshold distance, determines presence of fog ahead of the vehicle.
A fog detecting system for a vehicle, said fog detecting system comprising:
- a camera disposed at a vehicle and having a field of view forward of the vehicle, said camera capturing image data;
- a non-imaging sensor disposed at the vehicle and having a field of sensing forward of the vehicle, said non-imaging sensor capturing sensor data;
- a control comprising at least one data processor operable to process image data captured by said camera and sensor data captured by said non-imaging sensor;
- wherein said control, via processing at said at least one data processor of sensor data captured by said non-imaging sensor, detects an object in the field of sensing of said non-imaging sensor ahead of and being approached by the vehicle, and determines distance to the detected object;
- wherein said control is operable, via processing at said at least one data processor of image data captured by said camera, to determine presence of the detected object in the field of view of the camera;
- wherein said control, via processing at said at least one data processor of sensor data captured by said non-imaging sensor, detects the object and determines distance to the detect object before presence of the object is determined via processing at said at least one data processor of image data captured by said camera;
- and
- wherein, responsive to the determined distance being less than a threshold distance before presence of the object is determined via processing at said at least one data processor of image data captured by said camera, said control determines presence of fog ahead of the vehicle.
A fog detecting system for a vehicle, said fog detecting system comprising:
- a camera disposed at a vehicle and having a field of view forward of the vehicle, said camera capturing image data;
- a non-imaging sensor disposed at the vehicle and having a field of sensing forward of the vehicle, said non-imaging sensor capturing sensor data;
- a control comprising at least one data processor operable to process image data captured by said camera and sensor data captured by said non-imaging sensor;
- wherein said control is operable, via processing at said at least one data processor of sensor data captured by said non-imaging sensor, to detect an object in the field of sensing of said non-imaging sensor ahead of and being approached by the vehicle;
- wherein said control is operable, via processing at said at least one data processor of sensor data captured by said non-imaging sensor, to determine distance to the detected object;
- wherein said control is operable, responsive to processing at said at least one data processor of image data captured by said camera, to determine presence of an object in the field of view of the camera;
- wherein said control, responsive to the determined distance being less than a threshold distance at or before determination of presence of the object via processing at said at least one data processor of image data captured by said camera, determines presence of fog ahead of the vehicle;
- and
- wherein, responsive to determination that fog is present ahead of the vehicle, said control actuates fog lights of the vehicle and/or adjusts an adaptive cruise control system of the vehicle.
