Electronic Brake Distribution
As of yesterday I have an '07 Accord SE (4 cylinder). The "SE" Package lists "Electronic Brake Distribution"(EBD). When I asked the salesman what that was, he described it as a traction control and stability control system. I doubt very much that this was accurate information. Any forum members know what EBD really is?

RE: Electronic Brake Distribution
EBD is sorta like ABS but it's more sophisticated.
"Plain" ABS intervenes when one tire begins to slide. It reduces braking force at that wheel with an obvious hammering sensation. EBD can watch the slip ratio of the tires, & it can intervene long before the tire actually slides. It can make subtle adjustments to braking pressure at the wheels. During lighter braking the front & rear braking force are determined by the relative sizes of the caliper pistons. During heavier braking you want less force to the rear brakes as the rear axle unweights itself. The old way to do this is the brake proportioning valve. Stability control goes even further. Probably your Accord doesn't have it, because Honda would have been bragging about it in their literature... |

v6 accord have it now....(VSA) lifted right from the acura cars

(vehicle stability assist or something like that) |

Well that's new to me! That's sweet...

ORIGINAL: Chiovnidca Like yeuemy said, Honda calls they're stability contol VSA. (vehicle stability assist or something like that) Since EBD can already intervene 'smoothly' with braking force, the next trick is to use it to help you steer. A system like that can measure steering-wheel position so it 'knows' where you're trying to steer. Then it has yaw & roll accelerometers to measure where the car is actually going. So with a few extra sensors & a bunch of extra software, it can (for example) apply a little brake to one of the front wheels & help you go around a curve. |

RE: Electronic Brake Distribution
VSA is also on the 07 civic SI...I was test driving one and took note of that.

RE: Electronic Brake Distribution
Jim Blake explained it well. This is from Honda:
Electronic Brake Distribution The ABS system is further enhanced by Electronic Brake Distribution (EBD) which adjusts braking pressure front-to-rear, based on the weight distribution of passengers and/or cargo. Weight distribution is determined via the relative difference in rotational speed of the front and rear wheels. Greater braking pressure, and subsequently stopping power, is directed to the rear wheels when cargo loads in the rear are heavier. This contributes to a more controlled stop, and in conjunction with the front double wishbone suspension minimizes "brake dive" during hard braking. |
