2011 Peugeot 3008 Hybrid 4 wheel

26
PRESENTATION


The HYbrid4 technology allows two
sources of energy to be associated in an
effective manner: that of the Diesel HDi
engine which drives the front wheels and
that of the electric motor which drives
the rear wheels.
These two motors can operate alter-
nately or simultaneously, according to
the hybrid mode selected 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 slow speed and low load. It
also assists the Diesel engine when
moving off, accelerating and changing
gear.
The battery that powers the electric mo-
tor recharges itself during phases of
deceleration and stores the energy for
subsequent use.

Main parts of the hybrid system on 3008 HYbrid4

The Diesel 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 fi tted with the Stop & Start
system 5
which recharges the batteries and
provides additional power when needed (in 4x4 mode).

The 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 compartment in the boot, access to which is restricted to trained
service technicians.
The battery state of charge
is indicated by 8 horizontal or vertical bars (depending
on the screen).
The conventional battery
, located under the bonnet, powers the vehicle's 12 V
systems. It is recharged automatically by the high voltage network.

The electronic power
supervisor
4
automatically manages the operation of the
two power units (Diesel and electric) to provide the lowest consumption.
An inverter and a transformer are needed to manage the electric power.
The inverter 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 converts the 200 V of the battery pack to 12 V, to power the
vehicle's ancillary systems.

The Stop & Start system 5
allows the Diesel engine to be put into standby during
stops (traffi c lights, a stop, or in a traffi c jam, for example) or during phases of
running in all-electric mode.
The stopping and restarting of the Diesel engine is done in a way that is instanta-
neous and transparent for the driver.

The electronic gear control gearbox 6
provides, in automatic mode, signifi cant
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.

HYbrid4 MODE SELECTOR

The selector allows the user to choose
between 4 drive modes for the vehicle.
Turn the dial to the right or left; the mode
selected is confi rmed by illumination of
the corresponding indicator.


ZEV
mode, to force electric running
only.

Sport
mode, to make use of the maxi-
mum performance of the vehicle. Auto mode



4WD
mode, to force the vehicle into 4x4 mode.



It automatically manages the operation
of the Diesel engine and the electric
motor, according to inherent vehicle pa-
rameters, traffi c conditions and driving
style so as to optimise the vehicle's
fuel consumption
.
In particular, this mode activates "zero
emissions" electric running
when the
conditions allow.
In auto mode, the electric motor
:


- can drive the vehicle on its own up
to 36 mph (60 km/h) in "zero emis-
sions" electric running, depending
on the state of charge of the battery,
if the conditions specifi c to the ve-
hicle are met and if acceleration is
moderate,

-

supplements the Diesel engine

when moving off and changing gear,
during acceleration and when trac-
tion from the front wheels is inade-
quate (it automatically adds
4 wheel
drive
),


- is no longer active above 70 mph
(120 km/h).



AUTO
mode, for normal use and opti-
mised fuel consumption.


This standard
mode to use in
preference
is activated auto-
matically
on starting the hybrid
system.

ZEV mode *(all electric)Sport mode (Diesel and electric)

4WD mode ** (Diesel and electric)


Zero emissions vehicle operation is as-
sured 100 % by electric drive.
This mode forces silent running
at
moderate speeds.
This mode allows more dynamic driving
by providing additional performance
.
Vehicle acceleration and pick-up are
maximised by using the capacity of the
electric motor, supplementing the power
of the Diesel engine.
This mode manages the progressive-
ness of the accelerator, the automatic
gear control gearbox and the use of the
electric motor.
In Sport mode:


- The electric motor can be used up to
70 mph (120 km/h).


This mode provides additional trac-
tion

*** at low speed by driving all
4 wheels of the vehicle continuously:
the Diesel engine (front wheel drive) and
the electric motor (rear wheel drive) op-
erate simultaneously and permanently.
Their coupling is managed electronically
to optimise traction on slippery surfaces,
diffi cult terrain or severe conditions:
deep snow, mud, sand, …
In 4WD mode:


-
Power for the electric motor is provided,
if needed, by the alternator-starter
motor of the front engine. The Diesel
engine operates continuously.

- The additional traction from the elec-
tric motor is available up to 70 mph
(120 km/h).




*
ZEV: Zero Emissions Vehicle. In ZEV mode:


- the accelerator control is progres-
sive.

- Range and acceleration capacity
are limited. The maximum speed
possible is 36 mph (60 km/h).

- Under high load or a priority require-
ment causing the start of the Diesel
engine, the system changes auto-
matically to AUTO mode.


It can be activated when
the required conditions are
met, particularly if the state
of charge of high voltage
battery is suffi cient (4 bars minimum).

If the conditions allow, a mes-
sage "ZEV mode unavailable"
appears in the screen, the
ZEV warning lamp fl ashes for
a few seconds then goes off
and the selector comes on in AUTO.

**
4WD: 4 Wheel Drive.

***
This mode will be even more effec-
tive if suitable tyres are fi tted (winter
tyres in particular).

Examples of displays

On starting and when stationary
there is no fl ow of energy (the Stop & Start system
stops and restarts the Diesel engine automatically).
In auto mode, priority is given to the electric motor.

Energy recovery
During this phase (deceleration, braking, foot off the
accelerator, … all modes), the battery is recharged by
the electric motor/generator, itself driven by the rear
wheels.

100 % electric
In all electric running (AUTO or ZEV modes), only the
electric motor, powered by the battery, drives the rear
wheels.
The display of "Zero Emissions" indicates that the Diesel
engine is off and the vehicle is producing no CO
2.

VEHICLE RECOVERY

Before doing any work, switch off the
ignition and put the gear lever in posi-
tion N
.
The vehicle can be pushed for around
10 metres maximum. The front or rear wheels must not be on
the ground, use a fl at-bed lorry or trailer
to recover the vehicle.
Use the towing eyes only to pull a ve-
hicle out or to pull it onto a fl at-bed.
