System Safety
Some operating conditions concerning typical
manoeuvres which can occur during the use
of the vehicle are described below.
Vehicle Stationary Engine Running Gear En-
gaged (Typically 1st, 2nd Or R):
In this condition, if the brake and/or acceler-
ator pedal is pressed and the driver's door is
opened, the system maintains the current
gear while one of the two pedals is pressed.
The instrument panel displays the mode, log-
ic and the current gear; no acoustic warning
is emitted.
Vehicle Stationary Engine Running Gear En-
gaged (Typically 1st, 2nd Or R):
In this condition, if the brake and/or acceler-
ator pedal is NOT pressed and the driver's
door is opened, the system engages N (neu-
tral) after about 1.5
seconds
. The instrument
panel displays the mode, logic and
N
.
Vehicle Stationary Engine Running Gear En-
gaged (Typically 1st, 2nd Or R):
In this conditions if NO action is performed
for a timer longer than
3 minutes
(i.e. neither
the brake pedal nor the accelerator is
pressed (e.g. stopped at traffic lights), the
system independently selects N. The instru-
ment panel displays the mode, logic and
N
.
Vehicle Stationary Engine Running Gear En-
gaged (Typically 1st, 2nd Or R):
In this condition, if the brake pedal is pressed
and no action is performed for a timer longer
than 10 minutes, the system independently
selects N (neutral) and the instrument panel
displays the mode, logic and
N
.
Vehicle Stationary, Engine Running, Gearbox
in A Gear Other Than Neutral (N): Key-Off
Procedure:
In this condition, if the engine is switched off,
no information relating to the gearbox will be
displayed.
4. Summary of Buzzer Activation Requested
By the System:
List of conditions when the buzzer is activat-
ed:
1.
At start-up, when trying to start the en-
gine without brake pedal pressed.
2. When one of the following prohibited ma-
noeuvres is carried out:
Request of 3rd gear engagement with vehi-
cle stationary
Request of 1st gear engagement from re-
verse, with:
1)
Brake pedal not pressed
2)
Vehicle speed above 10 km/h
Reverse request with:
1)
Brake pedal not pressed
2)
Vehicle speed above 3 km/h
3.
N (neutral) request with accelerator
pressed
An acoustic signal that the vehicle has been
left with the gearbox in neutral is activated
(NOT CONTROLLED BY TCU).
Auto Calibrations:
Auto calibrations enable the system to oper-
ate correctly and are as follows:
Clutch bleeding
Accumulator depressurisation
Clutch self-calibration enablement
Grid self tuning/service auto calibration
New actuators
Deleting statistical data
Longitudinal acceleration signal learning
