DYNAMICS & CONTROL
But not everything is High Tec … at home
... Floating regulating mechanisms
developed in Greece in 250 years B.C.
Automatic control provides additional freedom to the car designer.
Unstable behavior improved by ESP 12
DYNAMICS & CONTROL
In our cars(Electronic Stability Program)
• Curving or under unstable conditions
breaking is applied selectively and independently
to each wheel. ...
Mercedes A: ESP
• 4 wheel automatic power control
Dynamic distribution of torque between front
and back wheel axis ...
Audi: Quattro• Fuel saving by automatic control of
valves opening
Honda Civic: VTEC
Well, let’s say that way !!!
