HCU to check for sudden actuation of the brakes.
With the brake pedal pressed, the ABS module
triggers emergency braking if the rate of increase
of hydraulic pressure exceeds the predetermined
limit.
If the brake pedal is pressed so hard that the ABS
becomes active on the front wheels then the ABS
control unit increases the pressure to the rear
wheel brakes up to the ABS intervention threshold.
EBA operation continues until the driver releases
the brake pedal sufficiently for the hydraulic
pressure in the HCU to drop below a threshold
value stored in the ABS module.
Trailer stability control:If the vehicle is ordered
with a trailer coupling then the Trailer Stability
Control function is integrated in the ESP. The ESP
detects snaking when driving with a trailer and
reduces the speed of the vehicle and trailer through
adapted braking and, if necessary, by also reducing
the engine output until the snaking movement of
the trailer is corrected.
Roll-over protection: The ESP dynamically
determines the tipping tendency of the vehicle and
works in conjunction with the EBA system to
prevent the vehicle from tipping over during
dynamic maneuvers like lane changing or while
negotiating bends.
Emergency brake light: The emergency brake
light automatically switches on the hazard flasher
system to warn drivers of other vehicles that
emergency braking is being initiated. Based on a
defined delay value, the ABS/ESP module sends
a signal to the generic electronic module (GEM)
via the CAN data bus. The GEM activates the
hazard flasher system, that then flashes 7 times.
Prerequisites for activation of the emergency brake
light are:
• The speed is higher than 50 km/h.
• The brake pedal is being actuated.
• The deceleration is greater than 9 m/s².
To prevent activation on snow or ice, for example,
the following prerequisites must be met:
• The speed is higher than 50 km/h.
• The brake pedal is being actuated.
• ABS regulation takes place.
• The deceleration is greater than 6 m/s².
Tire pressure monitoring system: The tire
pressure monitoring system used in the Kuga is
able to detect loss of air in a tire at an early stage
and warn the driver. Because it can only compare
the behaviour of the tyres with each other, it is not possible to draw conclusions about the absolute
tyre pressure. It is also not possible to monitor the
spare tyre pressure. In order for the system to
operate correctly, the tyre pressures must be
regularly checked and corrected and the system
subsequently initialised (see below).
The tire pressure monitoring system used here,
depending on the equipment level, is built into the
anti-lock braking system (ABS) as an extra function
and therefore does not have its own sensors.
The ABS module measures the loss of pressure
in the tyres by calculation using the wheel speed
sensors of the ABS system. If a tyre loses
pressure, its diameter decreases and the speed of
the wheel therefore increases. If the ABS module
detects such a loss in pressure, it sends a signal
to the instrument cluster via the CAN bus and a
warning message is displayed in the message
centre. The warning threshold depends among
other things on the dimension of the tyres being
used, the vehicle operating conditions and the
status at the last initialisation. Since neither the
absolute tyre pressure nor the position of the tyre
is known, the pressure of all the tyres must be
checked and the system re-initialised after a tyre
pressure warning. If necessary, the cause of the
loss of pressure must be investigated.
Regular tyre pressure checks are still necessary.
The system must be initialised after a tyre is
changed, winter or summer tyres fitted, the
pressures corrected or adjusted to suit the vehicle
load. This can be done by the driver using the
driver information system. For further information,
see: Owner’s Manual.

Use is made of opto-electronic types of sensors
with relative and absolute steering angle sensing.
For relative steering angle sensing, changes in the
steering angle are measured exclusively by the
sensor and transmitted to the ABS/ESP module.
With the aid of other vehicle status signals (e.g.
wheel speed sensors) the module calculates the
straight ahead position of the steering. For absolute
steering angle sensing, the sensor transmits a
specific signal to the module for each steering
angle position (in relation to one turn of the steering
wheel). The straight ahead position of the steering
is therefore defined in the sensor. On an absolute
steering angle sensor, several photoelectric barrier
modules are distributed around the segment disk
at varying distances. The gaps between segments
of the segment disk are also unequal. For each specific steering angle there is therefore a specific
switch status of all photoelectric barriers.

The HCU comprises the ABS module, the valve
block (with low-pressure accumulators) and the
ABS pump.
The valve block combines all of the brake pressure
control valves in one unit. Depending on the
system, either simple changeover valves or
proportioning valves (e.g. on EBD (electronic brake
force distribution) systems) are installed. The
low-pressure accumulators store the brake fluid
that is returned from the wheel brakes during the
pressure reduction phase until it is drawn back into
the system by the ABS pump.
The ABS pump is designed as a dual piston pump.
This means that two separate pump elements
assure an increase in brake pressure during control
interventions. A direct current motor drives the
pump pistons via an eccentric shaft.
The ABS/ESP module monitors the input signals
of all sensors and actuates the electro-magnetic
brake pressure valves and the ABS pump as
required. For reasons of safety, the module is of
the redundant type, whereby processing of the
signals is carried out via two separate processors
that also monitor each other.

Design:
• The gear ratios are achieved by means of acombined planetary gear set on the input side
and a Simpson set on the output side.
– The combined planetary gear set consists oftwo different, simple planetary gear sets. It
has a similar structure to a Ravigneaux set,
but with just one sun gear that engages with
the front planetary gears.
• Three multi-plate clutches
• Four multi-plate brakes • One band brake
• Two one-way clutches
The TCM adapts the gear changing to ensure that
the correct gear is selected for the style of driving,
the engine load, driver requirements, vehicle speed
etc.
The TCM features a self-learning strategy.
This leads to lower fuel consumption together with
improved comfort through smoother gear changes
and lower noise levels.

Depending on the input signals, the TCM mounted
on the transaxle actuates the solenoid valves
S1-S5 in the valve body. The solenoid valves are
either in the "open" or "closed" state.
The (SLT and SLS) control valves regulate the
hydraulic pressure according to the pulse/pause
ratio of the electrical PWM signal. The controlled
hydraulic pressure enables smooth shifting or the
generation of a defined slip through actuation of
the relevant clutches and brakes. The shift timing is calculated by the TCM using the
accelerator pedal position and vehicle speed.
Under normal conditions, gear shifting and torque
converter lockup occur at low engine speeds to
reduce fuel consumption.
If the accelerator pedal is pressed down quickly,
the TCM switches automatically into kickdown
mode.
