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.
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.
