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:

each damper to the appropriate level to maintain a flat and level body.
Roll Rate Control – Uses CAN inputs. Predicts vehicle roll rate due to driver steering inputs 100 times a second and increases damping to reduce roll rate.
Pitch Rate Control – Uses CAN inputs. Predicts vehicle pitch rate due to driver throttle and braking inputs 100 times a second and increases damping to reduce pitch rate.
Bump Rebound Control – Uses suspension height sensor and CAN inputs. Monitors the position of the wheel 500 times a second and increases the damping rate as the damper approaches the end of its travel.
Wheel Hop Control – Uses suspension height sensor and CAN inputs. Monitors the position of the wheel 500 times a second and detects when the wheel is at its natural frequency and increases the dampingto reduce vertical wheel
motion.

Under normal road conditions when the vehicle is stationary with the engine running, the dampers are set to the firm condition
to reduce power consumption.

The adaptive damping module receives its power supply via a relay and fuse in the CJB. The relay remains energized for a period of time after the ignition is off. This allows the adaptive damping module to record and store any DTC (diagnostic
trouble code) relating to adaptive dynamics system faults.



DAMPERS Component Description



Item Description A Front spring and damper assembly B Rear spring and damper assembly The 'Adaptive Dynamics' dampers are monotube, nitrogen gas and oil filled units, manufactured by Bilstein. The dampers are
continuously variable, which allows the damping force to be electrically adjusted when the vehicle is being driven. The variable
dampers provide the optimum compromise between vehicle control and ride comfort.

The dampers have an electrical connector on the end of the piston rod, in the center of the top mount (the dampers look
identical to those on the Computer Active Technology Suspension (CATS) system of 4.2L supercharged vehicles, but have a
different part number).

In each damper, the continuous damping adjustment is achieved by a solenoid operated variable orifice, which opens up an
alternative path for oil flow within the damper. When de-energized the bypass is closed and all the oil flows through the main
(firm) piston. When energized, the solenoid moves an armature and control blade, which work against a spring. The control
blade incorporates an orifice which slides inside a sintered housing to open up the bypass as required. In compression, oil
flows from the lower portion of the damper through a hollow piston rod, a separate soft (comfort) valve, the slider housing and
orifice and into the upper portion of the damper, thereby bypassing the main (firm) valve. In rebound the oil flows in the www.JagDocs.com
