Description and Operation

OVERVIEW

Adaptive Dynamics - Supercharged Vehicles from 2010MY

The adaptive dynamics system, is an electronically controlled suspension system which constantly adjusts the damping
characteristics of the suspension dampers in reaction to the existing driving conditions. The adaptive dynamics system is
available on specified models.

The system is controlled by an Adaptive Damping Module (ADM), located beneath the right-hand front seat. The module
receives signals from three dedicated vertical accelerometers; two at the front of the vehicle and one at the rear, which,
together with four suspension height sensors, determine the state of the body and wheel motions. In addition to these inputs,
further signals from other vehicle electronic system components to determine vehicle state and driver inputs are monitored by
the adaptive damping module. These combined signals are used by the adaptive damping module to continuously adjust the
damping characteristics of each of the suspension dampers in reaction to the current driving conditions to give the optimum
body control and vehicle ride.

PRINCIPLES OF OPERATION System Operation

The adaptive damping module uses a combination of information from other system modules and data from the accelerometers
and suspension height sensors to measure the vehicle and suspension states and driver inputs. Using this information, the
adaptive damping module applies algorithms to control the dampers for the current driving conditions.
The adaptive damping module receives signals on the high speed CAN bus from the following system components: Brake Pressure - ABS module. Brake Pressure Quality Factor - ABS module. Car Configuration Parameters - AJB. Center Differential Range Actual - ECM. Engine Speed - ECM. Engine Speed Quality Factor - ECM. Engine Torque Flywheel Actual - ECM. Engine Torque Flywheel Actual Quality Factor - ECM. Gear Position Target - TCM. Lateral Acceleration - ABS module. Power Mode (Ignition Signal) - CJB. Power Mode Quality Factor - CJB. Roll Stability Control Mode - ABS module. Steering Wheel Angle - ABS module. Steering Wheel Angle Speed - ABS module. Steering Wheel Angle Status - ABS module. Terrain Mode Requested - JaguarDrive selector.
Torque Converter Slip - TCM. Vehicle Information Parameters HS - AJB Vehicle Speed - ABS module. Vehicle Speed Quality Factor - ABS module. Front Left Wheel Speed - ABS module. Front Left Wheel Speed Quality Factor - ABS module. Front Right Wheel Speed - ABS module. Front Right Wheel Speed Quality Factor - ABS module. Rear Left Wheel Speed - ABS module. Rear Left Wheel Speed Quality Factor - ABS module. Rear Right Wheel Speed Quality Factor - ABS module. Rear Right Wheel Speed - ABS module. The adaptive damping module also outputs information on the high speed CAN bus for use by other systems as follows: Fault Message - instrument cluster.
Terrain Mode Change Status - JaguarDrive selector.
Terrain Mode - JaguarDrive selector.

The adaptive damping module monitors the input signals and operates the damper solenoids. The input signals are used in
control modes and a force required for each damper for that mode is calculated. An arbitration mode monitors the force
requirements from each mode and apportions a force to a damper. The force is converted to the appropriate current and sent to
the damper.
The control modes are as follows:
