Too much potential for false alarm by hawguy · 2011-08-01 12:01 · Score: 4, Interesting

Seems like way too much potential for false alarm - what happens when I'm driving along and thinking "Crap, I forgot to STOP for milk" or I see someone across the street about to get hit by a car and I think "That car's going to hit him, he better STOP! And my mind goes through the thought process of applying the brakes even though I don't do so"
I bet they can get nearly the same result by using motion sensors to detect the motion of the driver's foot off the gas pedal and over to the brakes - as soon as it sees the driver let up on the gas, it can prime the brakes and get ready for a panic stop based on the driver's next move - maybe instead of saving 12 feet of stopping distance they can only save 6 feet, but in a panic stop from 65mph, 6 feet (or even 12 feet) is rarely the different between a safe stop and an injury collision.
But an unexpected panic stop at 65mph with a 40 ton 18 wheeler right behind you could be fatal - even if he has this magic thought-control system, the laws of physics guarantee that your small car will stop faster than his heavy truck.

  If the trucker driver isn't tailgating (driving on a road too close to the vehicle in front, at a distance which does not guarantee that stopping to avoid collision is possible), it won't be a problem.

Once at around 50 mph there was an accident ahead of me and i slammed on the brakes.

An example of where that has happened, I was traveling on an interstate early in the morning, I saw a deer that was facing the roadway start and it looked as if it would jump out into the path of my car. As a result I lifted my foot off of the accelerator and started to move it to the brake. Before I got my foot to the brake, the deer had turned and darted away from the road. The system described in this article would have slammed on my brakes because that was what I was in the process of doing. However, because I was doing it with my foot, the situation changed before I got my foot to the brake and I aborted the action.
  The fact of the matter is that the overwhelming majority of "reaction time" accidents occur because the driver was travelling too fast for how far ahead they could recognize a potential danger (whether that was because of conditions or the amount of attention they were paying). Most of those drivers would have been traveling even faster if they had this sort of device. That is, the driver thought they could recognize a potential problem sooner than they actually could, if their reaction time had been reduced, they would have increased their speed to compensate for the additional time they had to react.

  "Slamming on the brakes sends a signal to the brake assist system, which senses the speed and pressure applied to the brake pedal. Emergency indicated, maximum clamping power is directed to the calipers and brake pistons as the Anti Lock Brake System (ABS) pumps the brake pedal. This maximum braking, while maintaining control stops the car as much as 45% faster than an equivalent vehicle without brake assist."

I just see city driving as a meatspace extension of the anonymous behavior theory acticulated by Penny Arcade. Drivers are effectively anonymous to other drivers, and so behave selfishly and often rudely. I try not to let it surprise me.

That solves the problem of a system failure that prevents the brakes from triggering. What about a failure that accidentally triggers the brakes? Unintentionally slamming on the brakes at 100 km/h could be very bad. TFA mentions this possibility, and says "more work needs to be done on avoiding false alarms."

Delays by olterman · 2011-08-01 18:16 · Score: 1

Most of the delay comes from your brain actually waking up, analyze and start braking. Another delay comes from your leg moving and pressing the brake.
The controlling part could be automated but not the analyzing part. Otherwise there will be false alarms.
I also hope they measure the brain activity from the correct place, i.e. from the motor pathway controlling the legs.
Maybe the best way would be to totally automate the simplest braking situations (i.e. brake when something is going to hit the car). Have good camera(s) and real time velocity measuring. Leave the more complex cases for the driver.
Best way to improve braking performance by Burning1 · 2011-08-01 19:49 · Score: 1

Although more efficient braking technology may improve braking distance by 10-20 feet, better awareness of ones surroundings can put a hundred feet of space between a driver and the hazard ahead without any changes in following distance or braking technology.
When we race, it's fairly typical to see following distances of a few feet at speeds in excess of a hundred miles per hour. We do this without brake light. Although rear end collisions do happen, it's actually a fairly atypical incident.

  Good point. Looking several cars ahead (while still aware of the ones in front of you) helps one notice brakes ahead and react earlier than if one were to wait for the guy in front of you to hit his brakes.
