3234854 - E7051 ROBOTIZED GEARBOX - Description (Smart gearbox)

Description

A control system called SELESPEED supervises and governs the operation of the manual gearbox via an electrohydraulic device.An electronic control unit manages a complex operating logic which enables the gearbox to be used in both 'semi-automatic' conditions, in which the driver manages the engagement of the gears using the lever or the two steering wheel buttons, and automatic 'CITY' mode which delegates gear change management to the electronic system.The electronic control unit dialogues with the engine management control unit via two dedicated lines (CAN), and receives the rpm, engine torque and engine temperature signals.The control unit drives, by means of a complex operating logic, an electrohydraulic unit located on the gearbox, via a specific electric pump.

The system is also controlled by means of two relays located near the control unit.The supply lines to the control unit and the various system components (sensors and actuators) are protected by two specific maxifuses and other jumper fuses, located next to the junction unit.
