3361154 - E7051 ROBOTIZED GEARBOX - Description (Smart gearbox)
Description
A control system supervises and governs
the operation of the manual gearbox via an electrohydraulic device
to create a robotised gearbox system.The system operates in two modes:
- SEMIAUTOMATIC MODE (MANUAL): the driver manages gear
engagement via the lever located on the tunnel.
- AUTOMATIC MODE (AUTO): the decision
to change gears is delegated to the electronic system, in accordance
with two strategies, the first aiming for driving comfort (NORMAL),
the second aiming to limit fuel consumption (ECO).
The electronic control unit communicates
with the engine management control unit via the CAN network and
two dedicated lines, one for the engine rpm signal and one for diagnostics.The control unit drives, by means of a complex
operating logic, an electrohydraulic unit located on the gearbox,
via a specific electric pump.

The supply lines to the control unit and
the various system components (sensors and actuators) are protected
by two fuses located in the engine compartment control unit.
Control unit self-diagnosis notifies of
the onset of these faults via a special warning light in the instrument
panel: The robotised gearbox control unit sends the instrument panel information
on the speed engaged. This is shown on the display. For more details,
