Conditions of use analysed
by the control unit
The control unit analyses each single
condition of use of the car, discriminating
it on the basis of the signals received
from the various sensors.
The conditions analysed are:
– starting (position/accelerator pedal
changing speed)
– acceleration (accelerator pedal com-
pletely pushing down speed)
– full load (number of engine full load
kickdown signals or position maintenance
time)
– braking (accelerator pedal release
time and braking system operation)
– type of programme (gearshift selector
lever position)
– winter driving (driving wheel skid-
ding/ABS sensors active)(only 3.0 V6
24V version)
– driving with trailer or uphill (car
speed in relation to transmitted torque)
– entering a bend (transversal accelera-
tion detected by the difference in the dif-
ference between the wheels of one side
and the other/ABS sensors active
– downhill driving (acceleration of the
car in relation to the position of the accel-
erator pedal)
– driving in town or queues (accelera-
tor pedal position and car speed)
– gear required by the driver (gearshift
selector level position).
Management of gearshift
programmes
To optimise vehicle handling the elec-
tronic control unit has the following mem-
orised programmes:
– automatic operation
– manual operation
– winter driving (only 3.0 V6 24V version)
– protection against high temperature
of the gearbox oil.
Automatic programme
In relation to the car speed and torque
transmitted, the control unit detects the s-
lope of the road surface and depending
on the sporty features chosen, it au-
tonomously chooses the programme most
suited to the situation.
Automatic sporty programme
(only 3.0 V6 24V version)
This function makes it possible to drive
sportively while exploiting automatic op-
eration of the gearbox.
To engage this function set the lever to
the left sector in the central position,
without moving it to (+) or (–): the
sportiest programme will remain engaged
until the lever is moved.
