 dirtyjefferAnons on ignore, but not due to fear.Premium join:2002-02-21 London, ON | Now THESE are brakes Saw this in another board in here and had to share it. That's some pretty impressive braking, especially with a 40 ton secured load. Volvo showing off their new Collision Warning with Emergency Braking system:

 | reply to dirtyjeffer Pretty cool stuff. I wonder if they are auto calibrating breaks so they always stay in alignment. |
|
 | reply to dirtyjeffer I wonder happens at highway speed if a car pulls in and cuts in short, will the system activate? What if the driver notices and swerves sharply as the system engages but he doesn't apply the brake, will the system keep breaking? |

What if the driver notices and swerves sharply as the system engages but he doesn't apply the brake, will the system keep breaking? I'd prob have it turned off in a city, maybe in adverse viability or long stretches of highway rolling.
I drive nothing near as big as that AZ rig and at least twice a week I have someone cut with a 1/4 car length, have to hard brake to reestablish a safe distance. That's the drivers job, having some system cut in to hard brake would be quite the change. -- AFK: Attack, fight, kill!! The healer is telling you to go pull mobs. WTF: Way to fight!

What if the driver notices and swerves sharply as the system engages but he doesn't apply the brake, will the system keep breaking? i believe the system looks for deceleration of the object in front of it (to sense an impending impact)...so if someone cut in front, but continued at a decent rate of speed, it wouldn't intervene...i believe the system automatically applies the brakes...when you look at that video, its ability to stop the truck in that last 15-20 feet is incredible. -- People sleep peaceably in their beds at night only because rough men stand ready to do violence on their behalf.

 | reply to dirtyjeffer It is quite impressive. May not do as well on a snowy Canadian road. Although I imagine if a collision were to occur this system would greatly reduce the damage and risk to life. |

| reply to dirtyjeffer The load on the trailer better be properly secured, or that kind of abrupt braking will send it flying towards the front!
But yeah, very impressive braking! All you see on the roads here is just slam the brakes and the trucks just lock up the brakes and skid. -- F**K THE NHL. Go Blue Jays 2013!!!

In that case it would be firing off a lot on the NYS I-90 as those idiots pass you at 1 mph speed differential and then pull in front of you 20' away and slow down. |

I was thinking about that Volvo video where the car smacked into the rear of the transport trailer and was wondering if the system didn't 'pick-up' enough 'reflection' from the rear of the trailer, ie. a typical car rear-end has more surface area with fewer 'gaps' to reflect ultrasonic energy from than the relatively 'open' area at the lower-rear of a transport trailer.
It seems that the ultrasonic system eventually sensed the trailer but about 20-30' later than it did in the other Volvo video where the transport was stopping behind a passenger car. |
