Autoliv develops next-gen alcohol sensing system

Autoliv has announced it has been selected as a partner to participate in the recently announced alcohol sensing feasibility project co-sponsored by the Automotive Coalition for Traffic Safety (ACTS) and the National Highway Traffic Safety Administration (NHTSA).

By making the detection system quicker, less intrusive, and less expensive than today’s systems, the funded project aims to gain greater public acceptance for an in-vehicle alcohol detection system in all cars.

The Autoliv approach is to identify small variations in the air composition within an arm-length to the driver’s mouth and nose. The intention is to use Infrared (IR) Spectroscopy as the sensing principle for both alcohol and CO2. By measuring the correlation between alcohol and CO2, the detection of the presence of alcohol within an arm-length of the driver can be accomplished. The unique prospect of this technology is to provide high sensitivity, specificity and system reliability at a reasonable cost.

Autoliv is working closely with SenseAir AB and Hok Instrument AB. Both of these companies have significant experience and expertise in the sensing, measuring and differentiating of alcohol versus other substances in the air.

The initial phase of this project is expected to be completed by July 2010.
