ATTESA E-TS System Info Please!

[Jimbo5]

Hi,

I'm currently studying the Skyline for a project at uni. The basic jist of it is the 'chassis electrical systems' such as traction control, ABS etc.

I chose the skyline because of its advanced ATTESA E-TS system. No doubt there are others systems on the car that I do not yet know about. If anyone has any good websites or links where I could find information on these systems, or if you could provide the information yourselves I would be very grateful.

Cheers

ATTESA ETS
-------------
Advanced Total Traction Engineering System for All
Electronic Torque Split

Basically - it runs the car in RWD until it needs front wheel traction. There is a PRO version which is fitted to the VSpec models. Takes a bit of getting used to while driving too

This comes from a website somewhere - can't remember exactly:

At the heart of the Skyline GT-R V-Spec, is the ATTESA-ETS PRO Electronic Torque Split system - making it arguably the most technologically advanced production car in the world today. Conceived for the JTCC to put 600 bhp on the track efficiently, ETS PRO satisfies the purist by giving all the advantages of rear wheel drive until conditions dictate otherwise.


At the heart of the Skyline GT-R V-Spec, is the ATTESA-ETS PRO Electronic Torque Split system - making it arguably the most technologically advanced production car in the world today. Conceived for the JTCC to put 600 bhp on the track efficiently, ETS PRO satisfies the purist by giving all the advantages of rear wheel drive until conditions dictate otherwise. A 16-bit microprocessor monitors wheel rotation as well as lateral and longitudinal acceleration 100 times a second. On detecting rear wheelspin and taking into account current driving conditions, it instantly instructs a wet multiplate clutch to direct more torque to the front wheels, regaining traction in a fraction of a second and letting the driver maintain control. The system comes into its own during hard cornering or in slippery conditions, when the front/rear torque split is adjusted to anything between 0:100 to 50:50. An active LSD on the rear axle further aids traction by calculating the optimum torque split between the left and right rear wheels, altering it to anything between diff. locked and free state. Working along with ATTESA-ETS PRO, is the SUPER HICAS rear-wheel steering system. This uses a series of sensors to monitor vehicle motion, rate of turn and the driver's actions on the steering wheel. Complex software then compares this information to computer predictions of the car's ideal turning characteristics, adjusting the angle of the rear wheels to reflect the driver's intentions. The result of all this technology? Neutral steering and unrivalled cornering capabilities.

The non V-Spec version of this car does without ATTESA-ETS PRO. At the track, the non V-Spec cars can be seen be fall far behind a V-Spec model.
