Development of calibration process for alco-lock sensors

Important results from the project

SenseAir plans to be Autoliv´s main supplier of high-performance alcohol sensors in large volumes. To manage the high demands within Automotive the production technology must be developed and quality certified. In addition, the production costs should be minimized by smart and efficient solutions which also make the environment safer. In the project we have built a Swedish Research Park for development and test of calibration processes for alcolock prototypes, aiming at a future high-volume production. The demonstrator at SenseAir is now tested with various kinds of prototypes.

Expected long term effects

Now, we can: * Calibrate alcolock prototypes in ethanol, carbon dioxide and temperature * Generate a well-tempered and accurate gasmix * Use a newly built and accurate reference sensor unit to control the gases * Perform the calibration in a specially designed chamber composed of optimised materials * Communicate with every individual alcolock sensor during the calibration process * Utilise a safe product / production line communication interface * Minimize the environment influence during each production sequence thanks to a shortened production time and gas consumption.

Approach and implementation

The project has been running for nearly two years, 2012-09-01 2014-06-30. The work was led by Professor Ingrid Bryntse at SenseAir together with responsible persons in various areas. Active members at Autoliv, Hök Instrument and SP have contributed to the excellent results. The project management group was led by Rauno Pyykkö at SP, Technical Research Institute of Sweden. The internal co-operation within the Project as well as in the Management Group was good, which led to a very satisfying result.
