WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

The Transfer Case Control Module (TCCM) is connected to the:

High Speed (HS) Controller Area Network (CAN) chassis systems bus.
High Speed (HS) Controller Area Network (CAN) powertrain systems bus.

The Intelligent Driveline Dynamics (IDD) system monitors the vehicle behavior, driver input and road surface conditions every 10 milliseconds. The IDD system optimizes torque distribution to deliver maximum traction performance, stability and yaw control.

The system comprises a torque distribution controller based on driver demanded torque, lateral acceleration and vehicle speed, which is configured to give the desired on-power handling balance. A traction controller responds to slip between the front and rear axles to ensure maximum traction performance. The system also has an intelligent yaw controller which continuously monitors the yaw behavior of the vehicle and responds to on-power oversteer conditions by transferring torque from the rear axle to the front axle to stabilize the vehicle.

The TCCM also features a reactive feedback loop to increase torque to the front axle if traction is lost and slip occurs. The TCCM works in conjunction with the Anti-lock Brake System (ABS) control module.

Torque on-demand benefits:

Full traction capability when required.
Supports a wide range of vehicle handling characteristics.
