SPEED CONTROL System Operation

The speed control system uses inputs from the brake lamp/brake test switch, the APP sensor, the ECM and the ABS module.
Speed control is operated by the driver using only the steering wheel switches. When speed control is active, the ECM regulates the PWM (pulse width modulation) signals to the fuel injectors to adjust the fuel supply as required to maintain the
set speed.

During speed control operation, the ECM controls vehicle speed by adjusting fuel injection duration and timing. When the accelerator pedal is pressed with speed control active, the ECM outputs a calculated throttle angle signal in place of the actual throttle angle signals produced by the APP sensor. The calculated throttle angle is derived from fuel demand.
The minimum set speed for speed control is 18 mph (30 (km/h). Speed control is automatically suspended if the following
conditions apply:

Vehicle speed falls below 18 mph (30 km/h)
The brake pedal is pressed
The cancel button is pressed
Neutral, park or reverse gear is selected
The difference between actual speed and the set speed is too great
If the engine speed becomes near to the red line (maximum engine speed)
If the accelerator pedal is used to accelerate beyond the set speed for too long.

ADAPTIVE SPEED CONTROL
The adaptive speed control system comprises the following components:
Adaptive speed control sensor
Adaptive speed control module
Steering wheel control switches
ECM
Electric throttle actuator
ABS module and pump Adaptive speed control warning indicator.

The adaptive speed control system uses a forward looking radar sensor to scan the road ahead, looking for objects that are
moving at a different rate to itself. When a target is identified the adaptive speed control system will monitor the time gap
between it and the target vehicle. When that gap falls below a set driver selected level the adaptive speed control system will
intervene slowing the vehicle by backing off the throttle and/ or applying the brakes, until the correct gap is attained. The
driver can chose between four gap settings, 1, 1.4, 1.8 and 2.2 seconds.
The system will detect but not react to the following:
Vehicles in the oncoming lane
Stationary vehicles
Pedestrians
Vehicles not in the same lane.

Adaptive speed control is active when the vehicle is moving. Adaptive Speed Control only functions when a set speed is
entered in normal speed control mode. The adaptive speed control system only intervenes with the set speed when it detects
a target vehicle, and then only if the minimum time gap is breached.

It is important to note that the system is intended for use in limited driving situations, does not remove control and
responsibility from the driver, and at all times can be quickly overridden. The adaptive speed control system is not a collision
warning system and will not react to stationary objects. The system does not operate below a minimum speed of
approximately 30 km/h (20 mph) since it is unsuitable for use in cities or congested traffic. The system is best suited to main
roads/ highways with gradual bends.
The ECM, throttle body and throttle control are unchanged from those used for non adaptive speed control variants.
The adaptive speed control system is based on the use of a front mounted radar sensor. The sensor transmits a 1.5° wide
beam forward of the vehicle and detects the returning signals reflected off other vehicles and objects ahead.
The 1.5° wide radar beam is mechanically scanned at a rate of 10 sweeps/second across a total arc of 15° centered on the

1 Set speed adjustment switch 2 Time gap switch (only on vehicles with adaptive speed control fitted) 3 Cancel switch 4 Resume switch The speed control switches are located on the RH (right-hand)side of the steering wheel. The switches are connected via fly
leads to the clock spring. The speed control switches are resistive ladder type switches which vary the resistance of a 5 volt
signal sent to them. The signal is returned along a LIN bus to the instrument cluster. The instrument cluster routes the control signals to the ECM on the medium speed CAN
Speed control is engaged by rotating the speed adjustment switch to the + or - positions. Once engaged the speed can be
varied by the speed adjustment switches. Each press of the speed adjustment switch will increase or decrease the set speed
in steps of 1 mph (2 kph).

ADAPTIVE SPEED CONTROL MODULE



The adaptive speed control module, located on the drivers side at the bottom of the 'A' post. The control module is connected
to the other vehicle systems via the high speed CAN bus. Signals from the adaptive speed control forward looking radar sensor are received on a dedicated CAN bus between the two modules.
ADAPTIVE SPEED CONTROL RADAR SENSOR



The adaptive speed control radar sensor is located in the front bumper, on the RH side above the radiator grill behind the bumper cover. The sensor is connected to the adaptive speed control, module via a private CAN bus. If the unit is replaced in service the unit must be re-aligned vertically. Horizontal alignment is achieved by putting the sensor in service mode using an
approved Jaguar diagnostic system.

systems.

A typical example of information transfer is vehicle speed information from the ABS (anti-lock brake system) module used to
control the automatic volume control function. The vehicle speed information from the ABS module is sent on the high speed
CAN network and collected by the instrument panel gateway. The signal is passed to the medium speed CAN network and onto the ICM gateway. The ICM calculates the volume adjustment required. The corrected audio volume level signal is sent on the
MOST network to the IAM or Power amplifier (dependant on vehicle equipment level) for output to the speaker system.

AUDIO SYSTEM USER CONTROLS

Touch-Screen



Item Description 1 Touch-screen 2 Home menu button 3 Touch-screen on/off button The Touch-screen forms the basis of the audio system. It communicates with the rest of the audio/infotainment system on the
MOST ring and allows control of the audio system and other infotainment systems from a single point.

The Touch-screen communicates with the IAM on the MOST ring and provides the primary user interface and display of the
audio system controls. No configuration procedure is required if the touch-screen is replaced.

Calibration of the Touch-screen using the Jaguar approved diagnostic equipment enables updates to be downloaded as new
technology becomes available or any fault concerns require software updates.
The touch-screen provides user control of the following systems:

System Functions Audio Radio display AM/FM or DAB, auxiliary and portable audio, digital TV or CD (compact disc) Climate
control Air conditioning, distribution, seats, heated steering wheel, automatic air recirculation Telephone Digit dialer, phone book, last ten calls (made, received, missed) Navigation Destination, stored locations, navigation setup, route options Vehicle
Security, parking, valet mode, trip computer, clock, brightness, contrast, system settings, vehicle settings, display settings

1 Volume adjustment 2 Change pre-set radio stations or CD tracks 3 Select audio source 4 Audio mute control/JaguarVoice control Additional control of the audio system is available in the form of steering wheel mounted switches which are located on the
left hand side of the steering wheel. The four switches provide for volume adjustment, change pre-set radio stations or CD tracks, select audio source and finally audio mute control. The mute control is also used for JaguarVoice control.

The steering wheel audio control switches are hardwired through the clock spring to the ICM. The ICM processes the analogue
signals from the switches into digital signals. The digital signals are then passed from the ICM onto the MOST system to
control the requested audio functions.

AVC (automatic volume control) controls the audio volume in relation to vehicle speed. As vehicle speed increases the audio
level is adjusted to compensate for extra road and vehicle noise. There are three settings for AVC:

Low
Medium
High
Setting of the AVC level is made using the audio controls. The default setting is medium.

The vehicle speed signal is used to enable the ICM to calculate the volume adjustment required. The vehicle speed signal is
received over the CAN. The signal is an average of the four wheel speed sensor signals. Should an invalid speed signal be received the AVC will not alter the output volume.



INTEGRATED AUDIO MODULE Component Description



The IAM is located in the center console behind the ICP faceplate, and combines the radio tuner and CD player. The head unit controls which of the two sources is routed to the speakers. All tuner versions have AM/FM reception. Each audio system
features auto-store, with a press and hold function to store selected channels as pre-sets. The standard search facility finds
the nine strongest channels currently available, while search and manual tuning allow channels to be stored as above.

The Jaguar Sound System IAM uses an internal amplifier which directly drives the system speakers. The Jaguar 320W Premium
Sound System and Bowers & Wilkins 440W Surround Sound System differs from the Jaguar Sound System with the addition of
an external amplifier. Audio output signals from the IAM are sent on the MOST system to the external amplifier which drives
the system speakers.

JaguarVoice control

JaguarVoice enables operation of several voice activated functions of the infotainment and climate control systems without the
need to touch any controls manually. The following systems include JaguarVoice functionality;

Navigation system
Phone system
Climate control system
Vehicle display system
Vehicle notepad

The 'notepad' facility allows voice notes to be recorded. Nametags for phone dialing and navigation locations allow the system
to be personalized and there is a help and tutorial function to provide advice on using the system.

The system allows the vehicle user to concentrate fully on driving the vehicle, without any need to divert their eyes from the
road ahead in order to check information read outs on the vehicle instrument panel information units. The voice control system
also feeds back audible information to the vehicle user.
JaguarVoice is a key component of the navigation system, allowing hands free control when issuing navigation commands.

The system is controlled by the voice button on the left hand side of the steering wheel. Voice commands are picked up by a
dedicated microphone. When giving a voice command audible feedback will be heard through the vehicle’s audio speakers.
