Three accelerometers are used in the adaptive dynamics system. The accelerometers are located as follows:
One each on the rear edge of the radiator support panel.
One in the luggage compartment, in the rear LH corner adjacent to the rear lamp assembly.
The accelerometers measure acceleration in the vertical plane and output a corresponding analogue signal to the adaptive
damping module. The algorithms in the adaptive damping module calculate the heave, pitch and roll motions of the vehicle,
which are used by the module to control road induced body modes.

Each accelerometer is connected to the adaptive damping module via three wires, which supply ground, 5 V supply and signal
return.

The sensing element comprises a single parallel plate capacitor, one plate of which moves relative to the other dependant on
the force (acceleration) applied. This causes the capacitance to change as a function of applied acceleration. This capacitance
is compared with a fixed reference capacitor in a bridge circuit and the signal is processed by means of a dedicated integrated
circuit to generate an output voltage that varies as a function of applied acceleration. The sensors output a signal voltage of
approximately 1 V/g ± 0.05 V/g.

SUSPENSION HEIGHT SENSORS



Four suspension height sensors are used in the adaptive dynamics system, two for the front suspension and two for the rear
suspension. A front suspension height sensor is attached to each side of the front subframes and connected by a sensor arm
and sensor link to the related lower lateral arm of the front suspension. A rear suspension height sensor is attached to each
side of the rear subframe and connected by a sensor arm and sensor link to the related upper control arm of the rear
suspension. On each suspension height sensor, the sensor arm and sensor link convert linear movement of the suspension into
rotary movement of the sensor shaft.
The sensors are also used for the static dynamic headlamp leveling system on vehicles fitted with xenon headlamps.

The suspension height sensors measure suspension displacement at each corner of the vehicle and output a corresponding
analogue signal to the adaptive damping module. The algorithms in the adaptive damping module calculate the position,
velocity and frequency content of the signals and use the results for wheel control.
Each suspension height sensor is connected to the adaptive damping module via three wires, which supply ground, 5 V supply
