The Q4 all - wheel drive system continuously monitors the vehicle's wheel speed, steering and
yaw angle as well as the wheel's grip and driving style.
Not exact matches
Instead, streams of numbers represent hairlines, eyebrows, nose structure, jaw lines, ears, scars or moles,
as well
as the head's pitch,
yaw and roll (head
angle, whether the chin is up or down, and how far off - center the face is).
As the corner unfolds a small
yaw angle builds and then stabilises, so you exit each corner with the car driving forwards but held in a shallow oversteering
angle.
Torque - vectoring systems are intended to mitigate understeer while cornering by sending torque to the outer rear wheel based on inputs such
as steering wheel
angle, lateral acceleration,
yaw and speed.
If you're pushing hard the front tires might feign to understeer but just
as they slip a degree or two wide the rear tires compensate, edging into a small but perfectly judged
yaw angle.
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.
During cornering, the rear drive unit pre-emptively diverts torque to the outer rear wheel immediately based on inputs such
as steering wheel
angle, lateral acceleration,
yaw and speed.
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.
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.
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 controller quickly recalculates the ideal distribution of the forces for each driving situation
as a function of the steering
angle,
yaw angle, lateral acceleration, speed and other information.
The controller constantly recalculates the ideal distribution of the forces for each driving situation
as a function of the steering
angle,
yaw angle, lateral acceleration, speed and other information.
Besides ensuring optimal traction during acceleration, the system also permanently monitors a wide range of sensory inputs — for example steering
angle, lateral acceleration,
yaw angle and speed — to distribute torque so
as to achieve optimum propulsion and safety for example on snow or to counteract sudden changes in road surface friction.
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.
When equipped with AWD, non-hybrid RAV4s use the same system
as the Toyota Highlander, pulling info like vehicle speed, steering speed, steering
angle, throttle
angle, and
yaw to calculate optimal torque distribution and maximize traction.
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.
Super Active
Yaw Control (SAYC) is the most technical
as it uses data from lateral and longitudinal acceleration, steering
angle and wheel speed to determine the best torque distribution for the rear wheels.
A sophisticated algorithm developed by Maserati continuously monitors dynamic inputs such
as wheel speed, steering and
yaw angle, and even wheel grip versus driving style.
