Titolo: The Optimal ABS Braking System.

Hi again,
"Whenever you look at a piece of work and you think the fellow was crazy,
then you want to pay some attention to that. One of you is likely to be, and
you had better find out which. It makes an awful lot of difference"
Charles F. Kettering.
1. The main idea behind the ABS Braking System is that the tires produce more
deceleration, that is a greater c_friction, when their speed is such that
Vtires_opt= Vcar / Kopt  >> 0        (1)
2. In (1) Kopt > 1, that is, 0<< Vtires_opt < Vcar.
Kopt must be determined experimentally for each triple (type of tires, type of
road, road state).
My bet is Kopt=2.37...
3. To obtain the exact car speed during hard braking, Vcar, we need to know
the exact car airspeed, Air_Speed, the exact Wind Speed, Vwind, the exact
wind direction, Wind_Direction, and the exact car direction, Car_Direction,
such that
Vcar= Air_Speed - Vwind cos alpha      (2)
where alpha is the angle between the wind direction and the car direction,
that is
alpha=Wind_Direction - Car_Direction   (3)
4. Kopt depends also on the weight on each wheel, on the type of road, on the
road state, on the tires type and on the tires state.
5. So we will need 4 speed sensors and 4 weight sensors connected to each
wheel, an Aircraft like airspeed sensor, a very accurate GPS, a communication
link with the Nearest Meteorological Station to get Vwind and Wind_Direction
in real time, an electronic compass to get the exact Car_Direction and 8
Video Cameras to identify the type of road, the road state and the tires
state.
Wow! Nuff Said!

CMC??? Ti bastano queste argomentazioni per spiegare qualche concetto
in più al carissimo Marco? :-))))))))))
