The car will know the driver is in full

The so-called " nollvisionens the goal is that a maximum of 220 persons killed in road traffic in 2020. Last year, the number was 223, of which more than twenty per cent of alcohol and / or drug. For each year reported well over 20,000 drunken driving offences.

The Swedish company Senseair manufactures sensors to measure air quality, and gashalt, in particular, ventilation equipment, etc. The current project has been going on since 2017, in co-operation with the trafiksäkerhetsföretaget Autoliv, and in the us this research project DADSS, the Driver Alcohol Detection System for Safety. , The red line shows the amount of carbon dioxide and the green-performance".

- demonstrates a prototype of the sensor technology in the newly renovated laboratory. On the gray tiles is a vehicle whose sensors are connected to a large monitor that shows graphs for each sensor.

sitting in the dörrsidan, and the one on the steering column behind the wheel. As soon as I get in the car, start it, take the red line on the screen to walk up and down. I'm not drunk yet, but the red line is measuring the level of carbon dioxide in the atmosphere.

the results will come so quickly is because of these sensors is based on infra-red technology instead of the conventional alkoholmätares fuel cell technology, which requires a much larger amount of air for the measurement. But, unlike the ignition interlock device that sits in the cars of the day, this is the infrared sensor to make the measurements continuously during the drive, but the driver needs to do something.

"It is important that the system is not going to interfere with a sober driver," said Jonas Ljungblad.

this is just going to put them in the car, the system automatically reads the ambient air and the operator can freely start the car and drive off if he or she is sober.

the Aim of the Senseair is to get car makers to integrate these new sensors as a standard in the manufacturing process, similar to the security that the antispin or autobroms. However, the road is a long one.

"It would be nice to get to a legal requirement that this be in new cars from a particular year, much like the US did with the backkameror in 2018," he says Are.

in a year, as a result of accidents involving reversing vehicles, whereas the alcohol-related deaths on the road amounted to the whole of the $ 10,000.

the Automakers are able to connect to the sensors with its security system, and in theory, the car would then be able to intervene, even while on the road, if the driver turns out to be drunk. Today may be partly self-driven cars are to drive into the side of the road and stop, if the driver does not react. This is a possible area of application of the system according to Jonas Ljungblad and Michael Are.

the latter is illuminated with a red light on the sensor, and the green graph is starting to yield results. The walk speed to 0.2 milligrams, which is equivalent to about 0.4 per mil per gallon of ethanol in the exhaled air and then to fall back on. I had been feeling in quite the concentration in the air is higher, and the grafutslaget sustained.

"of course, We have vision zero in Sweden, and we believe that it can help a great deal in order to achieve the objective, a large part of the traffic-related deaths are due to alcohol use," says Jonas Ljungblad.

the Swedish transport administration, the mention of just that in the IR-technology”, there will be more opportunities for outreach, both to the inclusion in the nybilstillverkning as for the retrofitting of the vehicles, the strategy for the years 2015 and 2020. One goal of vision zero is to achieve the 99.9% of sober drivers by 2020, a figure which, in the most recently published statistics, the low-on-99,73 per cent in 2018. As to when exactly we will be able to see the new technology in the market at present is not clear.
