The ID.4 - a Departure into a New Era

In the North American Region, the ID.4 launches a new defining model generation at Volkswagen.

It is an electric vehicle built on the new Modular Electric Drive Matrix (MEB), that networks with the internet, has digital display and control elements, natural
voice control and other pioneering technologies to signal the beginning of a new era.

Intelligent, innovative and sustainable – the ID.4

1

Introduction

Production Sites

The Volkswagen ID.4 is being built at Zwickau and Chattanooga.

Zwickau is playing a key role with the start of production: for the first time, a large car factory has been completely re-equipped for electric mobility. In the
final expansion stage from 2021, the Zwickau plant will build six electric models for three Group brands with a volume of up to 330,000 vehicles per year. The
site is developing into Europe’s largest and most efficient electric car factory and is leading the way in the transformation of Volkswagen’s global production
network.

Production of the ID.4 will be coming to Chattanooga in 2022. To support this, Volkswagen is expanding it’s Chattanooga operations with a 564,000 square­foot electric vehicle expansion and a 198,000 square foot battery pack assembly facility. This will solidify Volkswagen’s hub for electric vehicles in the region.
Along with increasing regional engineering capabilities, this step also supports the effort to localize all aspects of vehicle development and production.

Body

Body Structure Overview

The new strategy of the Modular Electric Drive Matrix (MEB) is based on the floorplan. The wheelbase is longer and the overhangs at the front and rear are
shorter compared with the MQB. The battery is bolted to the vehicle floor between the front and rear axles. A battery located on the vehicle floor provides a
lower center of gravity, more balanced weight distribution in the body and better driving dynamics.

The interior space is also greater because many components normally found in an internal-combustion engine vehicle have been removed, such as space for
the combustion engine, transmission, transmission tunnel, fuel tank and exhaust system. The electric drive motors are located directly on the axles, which
saves space and also lowers the center of gravity.

The front longitudinal members are connected directly
to the ultra-high strength hot formed footwell cross
member.

Transmission

One-speed Transmission 0MH

General Design

The single-speed transmission 0MH is attached to the Three-phase Current
Drive VX54 on the rear axle. When compared with the e-Golf transmission, it
is considerably more compact, lighter and durable. However, the transmission
design is very similar.

There is no longer a parking lock in the transmission. This function is
performed by the Electromechanical Parking Brake (EMPB).

The following parts are located in the transmission:

• Input shaft with gear Z1

• Output shaft with gears Z2 and Z3

• Differential with axle drive gear Z4

• Oil collector

The output shaft allows the overall ratio to be created in two steps (Z1 + Z2,
then Z3 + Z4). This creates a compact and lightweight design.

Driving Mode Selection and Parking Brake

The driving mode is selected using the drive mode selector located on
the steering column switch module.

The Electromechanical Parking Brake (EMPB) is activated with the
EMPB Button E538. The button is connected directly to the ABS
Control Module J104.

Driving Mode Selector

When the driving mode selector is turned to select a gear, two detents
can be overcome in both directions of rotation. If it is turned one
detent upward, the forward gear D is selected. If it is turned again in
that direction, it switches from D to B and vice versa.

Driving Mode Selector EMPB Button E538

If the switch is turned one detent downward from this driving mode,
driving mode N will be activated. If it is turned past two pressure
points, R will be immediately selected.

If, when turning upward, two pressure points are passed at once, the
D/B driving mode previously deselected will be active again. This fast
change allows the vehicle to be rocked free in case it is stuck.

When released, the driving mode selector will always spring back to its
initial position.

The EMPB is engaged by pressing the button E538 or by using the Auto
P function.

Climate Control

Classic Climate Menu

The Classic Climate menu has the familiar air conditioning system buttons and
functions.

If the Climatronic system is switched off, it can be activated using the ON/OFF
function or using the defrost function button in the light and visibility cluster.

The temperature regulation for the steering wheel and seat heating can also
be activated and adjusted on this screen.

Air Care Menu

This Air Care system has an air quality sensor to detect pollutants and an active
biogenic filter to prevent them from coming into the cabin. This special filter
is even more efficient than traditional pollen filters and stops fungal spores
and extremely small allergens.

When the Air Care function is activated in the Climatronic operating menu,
fresh air is drawn in. The proportion of recirculated air in the interior is mixed
and cleaned to provide a high level of air quality. In addition, an air quality
sensor detects if the ambient air is polluted with certain harmful substances.

If necessary, the Air Care Climatronic switches completely to air recirculation
mode so that pollutants such as exhaust gases from other vehicles do not
enter the interior.

25

Climate Control

Voice Control

Many operations in the ID.4 can be controlled using voice control. The system can be easily activated by saying “Hello ID...” (the wake-up phrase) or by pressing
the Voice button on the steering wheel.

The ID.4 will respond by saying by saying phrases such as “Yes?” or “What would you like to do?” and reacts intuitively to voice commands such as “I feel cold”
when the 2-zone Climatronic is installed. New digital microphones drastically improve voice recognition and quality when making phone calls and pinpoint
who is speaking (driver or front passenger).

Electrical System

Onboard Supply

The 12V battery is needed for the electrical demands of all 12V consumers. In addition, the 12-volt battery is needed to enable high voltage flow. The 12­volt system controls the high-voltage contactors that connect the high-voltage battery to the high-voltage circuit. A electric vehicle with discharged 12-volt
battery cannot be “started.”

Once the high voltage system is enabled, the Voltage Converter A19 provides the 12-volt vehicle electrical system with power from the high-voltage battery.

Vehicle activation is executed by both the Data Bus on Board Diagnostic Interface J533 (ICAS1) and the Vehicle Electrical System Control Module J519. The J533 is
the primary module. The J519 reads the ignition starter button and activates the terminal 15 relay.

Process Start: Vehicle unlocked /driver seat not occupied

Comfort Ready: Driver seat occupied, ignition off, air conditioning active,
infotainment active

Ignition switched on PARK

The key approaches the vehicle and the vehicle unlocks.

The "Comfort Ready" state allows the driver to operate the
infotainment system and the air conditioning even when the
ignition is off. It is activated when the seat occupied sensor
detects a weight. The vehicle key does not have to be inside the
vehicle.

The high-voltage circuit is audibly closed upon activation. A
"Welcome driver" message is displayed in the dash panel insert.

The ignition can be activated using either the ignition starter
button on the steering column or by pressing the brake pedal.
The display in the dash panel insert switches to the standard
view. In addition, all control displays are shown briefly.

The word PARK informs the driver that the parking brake is
activated.

Ready to Drive READY

40

To prepare the vehicle for driving, the driver needs to press the
brake and select a gear. The parking brake disengages and the
word READY appears in the dash panel insert.

The vehicle slowly starts to roll once the driver releases the
brake pedal.

The functions of J1254 differ greatly from MQB instrument clusters. For
example, Infotainment content, vehicle status and driving data are not
displayed. Also, the control module is not an immobilizer or component
protection subscriber.

Driving Mode Selector

The display is located in a housing with the drive mode selector and
the parking brake button. The component does not have its own
loudspeaker. All information and warning tones are output through the
audio system.

Sound System

Two sound systems are available for the ID.4:

• Basic sound: 4 + 1 speakers

• Premium sound: 6 + 1 speakers

The standard center speaker has two functions: it is used both for
music playback and for emergency call communication. To ensure
it functions in an emergency, it is connected to the Control Module
for Emergency Call Module and Communication Unit J949 (OCU).
The remaining speakers are controlled by the 4-channel amplifier
of the Information Electronics J794 (ICAS3).

The sound system speakers are used for all acoustic warnings in the
vehicle (parking aid and instrument cluster).
