Like my doctor told me...
"Vehicle Dynamic Control" provides 2-dimensional control by sensing the transversal movement of the vehicle and its yaw (rotation around the perpendicular axis). It uses these data to predict the vehicle's direction in 2 dimensions and to control it within safe limits. The system recognizes the course a driver wishes to take from the steering wheel angle and vehicle speed. It detects the current driving conditions from the wheel speed sensors, longitudinal and transversal G sensors and the yaw velocity sensor, and simultaneously estimates the coefficient of friction (potential loss of traction) of the road surface. It uses this information to predict the actual direction of the vehicle, and minimizes the difference between the desired and predicted course by controlling the driving and braking forces. When a potentially unstable situation is predicted because the desired course and the cars actual course differ, the braking and driving forces are controlled to regain stability. Vehicle speed is also limited if necessary by reducing engine output and torque.
Basically turn it off when you get inside the car, unless you have passengers.
It should be called "TFE" for "The Fun Eliminator", don't let the computer drive your car - you should drive your car!!
