IDD is an innovative system that manages torque split by sending all power to the rear axle in normal driving until it predicts, based on sensor data such
as yaw rate, steering wheel angle and lateral acceleration that torque should be diverted to the front axle.
It uses speed, steering and throttle angle as well
as yaw rate to determine how much drive needs to be sent to the rear treads, up to that 50:50 split where required, though interestingly it can head to 100:0 «when moving from standstill on slippery roads» up to 25km / h.

Active Four - Wheel Steering System (4WS) developed
as the first system of its kind in the world to use a
yaw rate sensor
The Dynamic Torque Control AWD system uses information sent from various sensors (speed, steering angle and speed, throttle angle and
yaw rate) to automatically govern the transmission of torque to the rear wheels,
as required.
Renault Sport's engineers say the system has enabled them to reduce body roll
as well
as influence the car's
rate of
yaw.
This system, standard equipment on the Polo GTI, accesses existing sensor data such
as steering wheel angle,
yaw rate and wheel speeds.
The most diverse parameters are taken into consideration here, such
as lateral acceleration, steering angle,
yaw rate, accelerator position, ABS control settings or the selected shift program of the 7G - DCT dual clutch transmission.
The LFA is equipped with Lexus's Vehicle Dynamic Integrated Management (VDIM) system, which co-ordinates the smooth operation of the ABS, vehicle stability and traction control systems
as the vehicle approaches its performance limits, based on critical data on brake operation,
yaw and roll
rates, individual wheel speed and longitudinal, lateral and vertical acceleration.
It makes the steering resistance higher
as the car's
yaw rate increases — which feels a lot more natural than many electronically assisted power steering systems.
The control is varied continuously,
as various sensors on the car measure speed; lateral and transverse acceleration, steering angles, tyre slip and other road surface and
yaw rate.
As a consequence, the activation of the stability control system reduces vehicle velocity, making the intervention practical for enhancing vehicle safety in critical transient conditions, identified when the offset between the reference value of vehicle
yaw rate and the actual value of vehicle
yaw rate exceeds assigned thresholds.
In its place is a fully networked set - up capable of analysing the driving conditions every 100 milliseconds and automatically providing either front - or four - wheel drive depending on factors such
as longitudinal acceleration, engine torque, steering angle,
yaw rate, prevailing traction and driving style.
