A series of sensors - for wheel speed, steering angle, longitudinal and lateral acceleration
, accelerator pedal position, engine speed - continuously evaluate the driving situation, while the all-wheel-drive electronics take all of the incoming data into account.
This configuration provides enhanced driving dynamics and higher lateral acceleration
on the road as well as improved traction when accelerating.
The all-wheel drive system is rear drive biased and varies torque split to the wheels depending on speed, lateral acceleration
, steering angles, tire slip, road surface and yaw rate.
The sensors permanently monitor both longitudinal and lateral acceleration
, as well as yaw rates and steering angles, to optimise front/rear torque split and thereby ensure the most efficient grip possible, while also reducing understeer or oversteer.
It measures vehicles lateral acceleration
, roll about its vertical axis through sensors, and applies brakes on selective wheels to control instability.
In all but one test, the longitudinal acceleration is reduced while the lateral acceleration
For the purpose of validating the vehicle motion induced by the crosswind input, driving tests were conducted to obtain the yaw rate (yawing angular velocity) and lateral acceleration
at the moment the vehicle passed through the crosswind zone.
The longitudinal acceleration and lateral acceleration
of vehicle are:
Rearward amplification of lateral acceleration
and yaw velocity;
The steering angle and the lateral acceleration
of the ego vehicle during lane changing process are shown in Figure 13 and Figure 14.

Trains usually slow down on curves to prevent unpleasant lateral acceleration
