Abstract:
The use of camera-based safety systems is growing at a rapid rate in automobiles where they are used to provide lane departure warning, collision avoidance, adaptive cruise control and other functions. As the industry moves towards full autonomous capability, the number of cameras and the resolution are increasing. For proper operation, the cameras require a clear undistorted field of view. Keeping the camera area free of snow and ice has been a problem. A resistive heating circuit is typically used to keep the area clear. For rapid clearing the circuit needs to operate at a high-power level. Due to the temperature dependent index of refraction of the plastic interlayer, severe distortion can result from the non-isothermal heating resulting from the spacing of the circuit elements. The laminate of the invention reduces distortion by removing the interlayer in the camera field of view and replacing with a plastic having a more temperature stable index of refraction.
