Presentation
The Hybrid4 technology allows two sources of energy to be associated in an effective manner:
the Diesel HDi engine, which drives the front
wheels and the electric motor, which drives the
rear wheels.
These two motors can operate alternately or simultaneously, according to the hybrid modeselected and the driving conditions.
The electric motor alone provides power for
the vehicle in "ZEV" (Zero Emissions Vehicle) mode, and in "Auto" mode for running at slowspeed and low load. It also assists the Dieselengine when moving off, accelerating and changing gear.
The battery that powers the electric motor is recharged during phases of deceleration andstores the energy for subsequent use.

Main parts of the Hybrid4 system

The HDi Diesel engine - 1
, located at the front, drives the front wheels and provides most of the power needed to drive the vehicle.
It is fitted with the Stop & Start
system - 5
which recharges the batteries and provides additional power when needed (in 4x4 mode).

Th
e electric motor - 2
, located at the rear, drives the rear wheels on its own, or supplements the Diesel engine, according to the hybrid mode selected.
It recovers energy and charges the batteries during phases of deceleration of the vehicle and is
active up to 70 mph (120 km/h).

A 200 V NI-MH high voltage battery - 3
, provides a source of energy for the rear electric motor.
Its charging rate is managed automatically by the vehicle during phases of deceleration.
It is located in a compar tment in the boot, access to which is restricted to trained ser vice
t
echnicians.

The batter
y state of chargeis indicated by 8 horizontal or vertical bars (depending on the screen).

Th
e conventional battery, located under the bonnet, powers the vehicle's 12 V systems. It is yrecharged automatically by the high voltage network.

The electronic power super visor - 4automatically manages the operation of the two power units(Diesel and electric) to provide the lowest consumption.
An inver ter and a transformer are needed to manage the electric power.
The inver ter acts on the torque of the electric motor, by regulating the current coming from the high
voltage battery pack. Its operating range is between 150 and 270 volts.
The transformer conver ts the 200 V of the battery pack to 12 V, to power the vehicle's ancillarysystems.
Th
e Stop & Start system - 5
allows the Diesel engine to be put into standby during stops (traffic
lights, a stop, or in a traffic jam, for example) or during phases of running in all-electric mode.
The stopping and restar ting of the Diesel engine is done in a way that is instantaneous and
transparent for the driver.
Th
e electronicgearbox - 6provides, in automatic mode, significant savings in fuel consumption compared to a conventional manual gearbox, thanks to its electronic control system.
It also offers improved driving pleasure with the possibility at any time of choosing the gear changing mode: automatic or manual, using the paddles located behind the steering wheel.
