Supplier Brose says that a new generation of Brose control units will integrate all door functions from the window regulator to collision protection. This, it claims, will cut costs, save space and reduce weight while enabling new functions such as noise cancelling.
Brose says that the door can be opened by a 'simple gesture' and a radar sensor scans the environment to prevent any collisions. While driving, monitors in the doors show the image from the side cameras in real time. At the same time, passengers inside the vehicle enjoy a quiet ride thanks to the speaker control, which besides active noise cancelling also enhances the sound of the infotainment system.

Brose says one of the greatest challenges is analysing sensor data or transmitting image signals – something that pushes conventional electrical and electronics architectures to their limits as large volumes of data need to be transmitted and processed without any noticeable delay. Solving this problem with a central processing unit requires long cable routes, which increases costs and latencies.
This, it says, is the reason why Brose is developing a new generation of door control units that processes all functions in the door locally – and it includes innovative approaches such as voice recognition in the vicinity of the vehicle as well as pre-processing of all received antenna signals. A single broadband line connects directly to the central control unit, saving space and costs by eliminating more than 30 cables in the door interface, Brose says.
Brose says it has the in-house expertise to integrate all functions into the entire system, thereby further reducing the technical and financial expenditure for OEMs. The first all-in-one door control unit could go into series production as early as 2025.
