E-Q2 Electronic system Q2

The E-Q2 electronic system uses the effect of the braking system, which is effectively controlled by the ESP control unit - in the case of the Alfa Romeo VDC. The system attempts to mimic the effects of a limited differential mechanical differential. The E-Q2 system helps with cornering. When cornering, the car leans and the inner wheel is unloaded due to centrifugal force. In practice, this means shifting and reducing traction - the grip of the wheel on the road and the transmission of the vehicle's driving force. The VDC control unit constantly monitors vehicle speed, centrifugal acceleration and steering angle, and then estimates the required brake pressure on the inner light wheel. Due to the braking of the shifting inner wheel, a large driving force is applied to the outer loaded wheel. This is exactly the same force as when braking the inside wheel. As a result, understeer is greatly eliminated, there is no need to turn the steering wheel so much, and the car holds the road better. In other words, turning can be a little faster with this system.
