Door Control Units – The Control Center for Various Functions in the Door Area

To efficiently control the increasing number of components and functions installed in the door zone such as switches and sensors, actuators and interior lighting components, many vehicle manufacturers are implementing dedicated Door Control Units (DCUs).

The application of one single control unit, responsible for all of those area related functions offers a number of advantages. The OEM can design individual and cost optimized vehicle architectures by using customized DCUs.

Integrating several functions into one central ECU (electronic control unit) also means less stand-alone components and wiring harnesses. Therefore Door Control Units also support the reduction of weight and overall energy consumption.

Door Control Units – Enhanced Convenience and Advantages all Around for Doors

The door system or Door Control Unit (DCU) makes the use and operation of the doors as convenient as possible. It offers, for instance, electrical window lift with anti pinch protection, closing and locking functions (including child security lock), side mirror functionality and convenience and interior lighting in the door handle. It communicates with other components via a CAN/LIN bus.

The electronic components can be designed as motor-integrated or stand-alone (only DCU) units depending on the functional content and the electrical architecture in the door zone.


Our standardized hardware and software platform concepts for Door Control Units offer many cost advantages to both OEM as well as Tier 1 customers and always guarantee high quality.

The current based anti-pinch function is realized via hall sensor technology or Sensorless Positioning (SLP) counting and meets all significant market and legal requirements especially for Europe and the USA.

  • Less stand-alone components in the doors
  • Optimized wiring harness architecture in the doors
  • Minimal production costs and reduced weight
  • Anti pinch protection easily adaptable to the mechanical system
  • Enhanced reliability thanks to fewer connections
