Re: ABS5 (what in the world is it!?)

Some people here at the mechanical engineering department were discussing 
this. As I understood the latest in ABS is electronic proportioning 
mechanism to more properly vary pressures in the back wheels to avoid over 
steer during breaking because of marginal lock up. (during a corner 
inside and outside wheels travel at different velocities, add to this 
different surfaces- ice, snow... the situation is complex) So instead of 
a simple hydrolic proportioning system used on the ABS4 they now use more 
complex fuzzy logic microporcessor controlled unit on ABS5. 

Not so much to revolutionize braking (although it does to wonders) - it is 
more reliable and permits easy integration into AWD and alternative 
engines of the future.
