ADAS Product Development

smartmicro has been working with many 1st tier automotive suppliers, some of them being among the top 10 worldwide, to support their development- and/or production programs. We design and develop Radars according to end customer (OEM) specifications. The sensors are then always built on the 1st tier's manufacturing line. Training is provided for field application and production engineers of the supplier, as well as life-long product support for the supplier.

In close cooperation with the leading semiconductor manufacturers, we make reference
designs for automotive sensors:

  • CATegory 4 4D/UHD 76-77GHz.
    • Single board.
    • Forward looking applications like MRR for FCW/ACC/AEB.
  • CATegory 5 and 6 4D/UHD wide bandwidth 76-81GHz.
    • Single Board, single chip (CATegory 6) SRR.
    • Rear corner applications like BSD/LCA(C)/RCTA/RCW/Exit Assist.
    • Front corner applications like FCTA.
    • Parking, 360 degree sensor fusion.
  • CATegory 7 4D/UHD wide bandwidth 76-81GHz.
    • Single board, single chip.
    • Interior applications like child-left-behind, gesture and motion detection.
  • CATegory 8 4D/PixelHD wide bandwidth 76-81GHz.
    • Imaging radar, with true resolution in 2 axes (az./el.).
    • Dual board.

smartmicro Design Know-How

smartmicro is in typically responsible for the A-, B- and in some cases even for C sample development and for mechanical- and production line design. In all cases smartmicro does the overall system design, development and verification testing including:

  • Antenna system, RF hardware, transmit waveform 
  • Complete hardware, digital and RF 
  • Signal processing software, 
  • Object tracking software and function algorithm (warning, distance control, ...) 
  • Vehicle data, other sensor data and Radar data fusion algorithms

Cost optimization during design- and manufacturing is continuously addressed in close cooperation with the supplier. 

smartmicro Track Record

Millions of automobiles worldwide carry Radar sensors designed by smartmicro. smartmicro has invented the Lane Change Assist (LCA) Radar, in partnership with Audi and started production in 2006 with a production partner. The patented technology was later enhanced by introducing additional functions like Blind Spot Detection (BSD) (2nd generation in 2012), Rear Cross Traffic Assist (RCTA) and Rear Collision Warning (RCW).

Longer range Forward Collision Warning (FCW) sensors went in production in 2008. Today 76-81GHz sensors are manufactured for Adaptive Cruise Control (ACC), Automatic Emergency Braking (AEB) and other functions in the 4th generation. Customers like Audi, Volkswagen, BMW, Mazda, Porsche, PSA and Hyundai/Kia use smartmicro technology.

smartmicro Background

Prof. Dr. Hermann Rohling and Dr. Ralph Mende worked at the Technical University of Braunschweig on automotive Radar since 1993, and founded smartmicro in 1997. With over 20 years of experience in the design and development of automotive driver assistance systems (ADAS), and with 125 employees today, mostly highly specialized engineers, many of them with 10year+ experience, smartmicro has a long and successful track record.
