Default Drunk & Driving? Your car won't start!

Volvo has launched this new device called Alcoguard to curb the alcohol related road mishaps. This should be made mandatory in all calls. works on fuel-cell technology which is expensive but if demand grows then we might see one of these devices in every car. read more here
Quote:
Volvo Cars is the first car manufacturer to launch an innovative feature aimed at helping to reduce the number of road accidents caused by drink-driving. Alcoguard is a fully integrated in-car alcolock that utilises advanced fuel-cell technology, a solution that is both user-friendly and reliable.

Alcoguard is a tool whose purpose is to help the driver make sober decisions. At present, one in every three traffic fatalities in Europe is alcohol-related. Our three biggest challenges for creating a safer traffic environment are speeding, insufficient safety belt use and drink-driving. The aim of our product is to help reduce the number of accidents caused by vehicles with a drunk driver at the wheel," says Ingrid Skogsmo, director of the Volvo Cars Safety Centre.

Alcoguard utilises fuel-cell technology - the very same technology that is used by most police forces in Europe. Before the car can be started, the driver has to blow into the wireless hand-held unit. This unit is the size of a small remote control and it is stored and charged in a compartment behind the centre console. The driver's breath is analysed in the hand-held unit which then transmits the results via radio signal to the car's electronic control system. If the blood-alcohol limit of 0.2 g/l is exceeded, the engine will not start. Thanks to advanced sensors, it is not possible to use external air sources such as a pump to cheat the system.

Alcoguard will be available as an option on the Volvo S80, V70 and XC70 from the start of 2008, and by next summer it will also be available on the company's smaller car models. Sales of about two thousand units are expected a year, and this figure is expected to increase as time goes by. Sweden is today the biggest market for alcolocks but Volvo Cars will also offer the system in the rest of Europe and in the USA. The company-car sector, taxi operators, state authorities and municipalities will probably be the foremost customer groups, although the enhanced user-friendliness means that private car owners will also be potential customers.

David Nilsson, Technical Project Manager for Alcoguard at Volvo Cars, says that fuel cell technology is prime for breathalyzers. "Fuel-cell technology is more expensive but it also produces far better results. Unlike semi-conductors, for instance, fuel-cells only react to ethanol and nothing else. In the fuel-cell, the ethanol molecules pass through a sensitive membrane and an electrical current is generated. This current is then measured. Higher current means more alcohol in the driver's breath," he said in a release. Whaddya know, ethanol and fuel cells in an AutoblogGreen post, but neither is mentioned in the way you'd think.

Step in the right direction, but still not an absolute solution. In India, anyone can make the watchman / paanwala / valet guy blow in to start the car. And then drive away themselves.

It has to be something smarter.

Default Technology to curb drunk driving

...alcohol consumption could be detected as soon the driver touches the steering or takes breath inside and the vehicle won't start.
Some comments:

- Why would a car owner pay for such a feature? If he is not a drinker, he wouldn't need it and if he is, he wouldn't want it!

- If it is mandated by law, it can be installed, but then so are seat belts. Do not recollect seeing a feature where, if seat belt is not fastened the car won't start at all.

- Finally, people might easily find ways to disable the safety mechanism. After all it's their vehicle.

- A prominent warning (rather than vehicle lockout, just like seat belts) might be a better idea.

IMHO, not sure how much this will work here. A responsible driver will never think about driving after drinking. People in the other category will always find a loophole or as you mentioned, disable this. Well, thats why they belong in that category.

hey, what happens if this equipment smells alcohol from the passenger but wrongly identifies that the driver is drunk?? I don't think going by smell from breathe would be the right detection technique. And how can steering wheel touch detect this?

In several countries alcohol locks could be mandated by court order to be installed in the car.

I found this that shows a bit more detail on how it works, note that you have to keep blowing into the thing during the journey.

http://www.transport.nt.gov.au/mvr/a...ignition-locks

Here's another interesting article that also mentioned the effectiveness of these alcohol locks. Apparently it is pretty effective in preventing drink driving recidivism!

Quote:
Large scale quantitative research on alcohol ignition interlocks in use has shown that alcohol interlocks are 40 to 95 percent more effective in preventing drink driving recidivism than traditional measures such as license withdrawal or fines [45]. A literature review (UK Department for Transport, 2004) showed a recidivism reduction of about 28-65% in the period where the alcohol interlock is installed compared with the control groups who were not using the alcohol interlock. An EU study indicated that alcohol interlocks need to be fitted permanently to have an effect, for after removal of the lock recidivism increases again [5]. Alcohol interlocks clearly have an important role to play within rehabilitation programmes.

One of the drivers in my office,(We have large fleet of buses and Light vehicles) got a metal clip made, just like the one with the seatbelt, to be put in the slot for the seat belt so that the indicator will not blink!
That much he hates wearing seat belt! What to do with such people? And once you board his vehicle, even if you are an athiest, you will immediately be converted into a firm believer in divine intervention! Such is his driving style!

Default Drunk driving tracker?

Hello Members.

Moderators: I was not sure what category to post this under hence leaving it here for your review. I couldn't find other posts on the topic so kindly move this there if one exists already.

I was reading about the car crash that killed the young actress Jessica Falkholt and wiped out a number of her family members too recently (RIP). Supposedly the crash was caused due to the other driver who was under the influence of drugs/ alcohol.

There are thousands of accidents in India that happen on a daily basis but I was surprised that car crashes (as opposed to car accidents) do happen in countries that have more organized driving and stringent checks too. Goes to prove that inconsiderate drunks are alike everywhere. Agreed that it is not too long before cars would not have killer morons behind the wheels but it is still a few years away at least in chaotic India?

What I was wondering is that there could be technology already that can be fine tuned/ retrofitted to put to use against drunk driving?

* There is supposedly a wristband that can track your alcohol content based on the chemical composition of your perspiration. That could probably be easily incorporated onto the steering wheel so that then cars can continuously monitor the driver for drunk driving? We already have cheap bands that give vital body stats so a lot of the information is already available.

* While may not be 100% accurate but the air con system can be programmed to analyze the air continuously to check for alcohol content. May be with inlets placed strategically near the headrests or above the driver.

* With machine learning and AI capabilities, combined with other current sensor details, the car could be programmed to detect uncanny driver inputs to identify drunk driving patterns. We already have sensors/ cameras that can detect driver fatigue. We do also have lane departure warning systems so looks like a lot of the data capture systems are already there?

Once the vehicle detects drunk driving, it could go into limp mode or even be programmed to warn other road users/ enforcement agencies via external cues?

While dim-witted morons will still find ways to crack the system, it is probably better than the random police checks or at least will act as a deterrent? Who would want to drive around a car with its lights blinking like a Christmas tree and horn blaring at intermittent intervals unless of course the person is too drunk to care about it .

Thoughts appreciated!

He needs to be educated and forcibly made to watch videos showing fatalities because of not wearing seat belts. If he doesn't mend his ways, he should be shown the door.
I remember how bikers would avoid wearing helmets citing inconveniences. Now the same people wear them although only when they know they are being watched. I still hate to see bikers who wear helmets but have their family members including small children ride without any protection. We need to do more on spreading awareness.
