Abstract
A detection-system for a vehicle to detect the presence of one or more object relative to the vehicle comprises a module-housing, a radar sensor component located within the module-housing for emitting a radar beam and receiving reflected signals in a detection mode. The radar sensor component comprises means for emitting a defrost beam in a defrost mode; the defrost beam overlapping the radar beam. The detection-system further comprises an absorber material located in the field of view of the defrost beam to absorb the energy of the defrost beam and to warm up in view to provide a defrosting effect.
Claims20
A detection-system for a vehicle to detect the presence of one or more objects relative to the vehicle, said detection-system comprising:
- a module-housing;
- and
- a radar sensor component located within the module-housing for emitting a radar beam and receiving reflected signals in a detection mode, wherein
- the radar sensor component comprises means for emitting a separate defrost beam in a defrost mode, said separate defrost beam overlapping the radar beam, and
- the detection-system further comprising an absorber material located in the field of view of both the defrost beam and the radar beam to absorb the energy of the defrost beam and to warm up in view to provide a defrosting effect.
A control method for a detection-system, said method comprising the steps of:
- operating the detection-system in a radar mode by using a radar sensor component to emit a radar beam and to receive reflected radar beam signals;
- and
- operating the detection-system in a defrost mode by using the radar sensor component to emit a separate defrost beam toward an absorber material placed in the field of view of both the defrost beam and the radar beam and thermally coupled with a body part of a vehicle through which the radar beam passes, the separate defrost beam being suitable for warming up the absorber material and for providing a defrost effect on the body part.
