Situation

Advanced driver assistance systems (ADAS) pave the way to self-driving vehicles. In 2022, they will become mandatory in the EU in order to improve road safety. To achieve this objective, the camera, Radar and LiDAR (light detection and ranging) systems have to accurately function in all weather conditions. Especially at freezing temperatures, sensors must be deiced quickly and kept ice-free while the vehicle is on the road.

Solution

Schreiner ProTech offers innovative film heaters based on printed electronics specifically for ADAS applications. Installed in the enclosures of camera, Radar or LiDAR systems, they ensure reliable and permanent deicing of the sensors. The functional films are flat and flexible, which makes them an ideal solution for heating elements. Due to state-of-the-art die-cutting and printing techniques, even complex contours with tight tolerances are easily achieved.

Benefit

  • Very light weight due to flat film structure, allowing for integration on the sensor with minimal space requirements.
  • The flexibility of the film and variable design of the conductive tracks allow for customization of the film heater in terms of shape and size and adaptation to any geometry and curvature of the component.
  • Heating performance can be individually adapted to customer needs, sensor and ambient conditions.
  • The film can be efficiently integrated into existing customer processes such as adhesive bonding, insert molding and clamping.
  • The self-adhesive version of the heating solution reduces installation requirements.
  • The planar surface of the printed heating structures avoids the conductive tracks possibly being visible in installed condition.
  • Homogeneous heating performance ensures complete deicing in winter.
  • The possibility of positioning the film heater close to the object to be heated supports fast heating, which ensures reliable sensor performance.
