ROBOTIZED GEARBOX - Description

2.0 TS · Selespeed 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 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.

For more details, Characteristic of working principle 2127 ELECTRO-HYDRAULIC SELECTION. GEARBOX EXTERNAL. CONTROLS.

The supply lines to the control unit and the various system components (sensors and actuators) are protected by two fuses located in the underfacia control unit.

A special fuse in the engine compartment junction unit supplies the line for the system electric pump.

Control unit self-diagnosis notifies of the onset of these faults via a special warning light in the instrument panel: The SELESPEED control unit sends the instrument panel information on the speed engaged. This is shown on the display. For more details, Characteristic of working principle 2127 ELECTRO-HYDRAULIC SELECTION. GEARBOX EXTERNAL. CONTROLS.
