Abstract
The invention relates to a sensor arrangement for a motor vehicle, with a pane, a sensor housing, and an optical sensor, wherein the sensor housing is arranged on one side of the pane such that between the sensor housing and the pane, a gap is formed, in which the optical sensor is arranged. To allow for a deicing of the pane in an area of the sensor housing in a particularly simple and thus cost-effective manner, it is provided that between the sensor housing and the side of the pane, a heat conducting element is arranged to conduct heat from outside the sensor housing in between the sensor housing and the pane.
Claims20
A sensor arrangement for a motor vehicle, comprising:
- a pane;
- an optical sensor;
- a sensor housing disposed on an inner side of the pane such that a gap is formed between the sensor housing and the inner side of the pane, and wherein the optical sensor is disposed in the gap;
- and
- a heat conductor disposed between the sensor housing and the inner side of the pane, the heat conductor configured to conduct heat from between an outside of the sensor housing and the pane,
- wherein the heat conductor is disposed both inside and outside the gap, the heat conductor projecting into an interior of the motor vehicle to thereby be heated by heated air in the interior.
A motor vehicle with a sensor arrangement, wherein the sensor arrangement comprises:
- a pane;
- an optical sensor;
- a sensor housing disposed with the optical sensor on an inner side of the pane of the motor vehicle, wherein the sensor housing is further disposed to form a gap on the inner side of the pane between the sensor housing and the pane, and wherein the optical sensor is disposed within the gap;
- and
- a heat conductor disposed between the sensor housing and the inner side of the pane, the heat conductor configured to conduct heat from outside the sensor housing to an area between the sensor housing and the pane,
- wherein the heat conductor is disposed both inside and outside the gap, the heat conductor projecting into an interior of the motor vehicle to thereby be heated by heated air in the interior.
A method for operating a sensor arrangement for a motor vehicle, the method comprising:
- conducting heat, by a heat conductor, from an interior of the motor vehicle to an area of a pane between a sensor housing of the sensor arrangement and the pane, wherein the sensor housing is disposed on an inner side of the pane so as to form a gap between the sensor housing and the pane, in which an optical sensor is disposed;
- and
- heating, by the heat conductor, the area of the pane,
- wherein the heat conductor is disposed both inside and outside the gap, the heat conductor projecting into the interior of the motor vehicle to thereby be heated by heated air in the interior.
