Life is not constant; increasing urbanization, new establishments and ageing population leads to evolution of the transportation
systems. Present situation is tried to be developed while the valuable legacy inherited from the past is tried to be protected.
“Ethos with regard to Equality” directs every citizen to be involved in every phase of the life. Ethos and regulations also affect the
vehicle designs which would enable to increase mobility of the disabled and aged population.
Karsan ATAK meets the parameters of the public transportation today. It is an efficient and contemporary public transport vehicle.
Moreover, price increases in petroleum products, high fuel consumption values, increasing cost of labor, the negative effect of the
Economic Crisis to incomes and environmental concerns basically shape up the customer needs and requirements.
These parameters are forcing the manufacturers to provide solutions and offer efficient and contemporary and green vehicles.
Buses in middle dimensions offer optimum solutions for relative high passenger capacity and low fuel consumptions. These types
of vehicles have begun to penetrate the markets by increasing numbers due to low costs and low emission values.
ATAK is a vehicle designed for public transport purposes and its optimum dimensions along with components selected and
engineered rigorously makes ATAK an efficient vehicle, featuring low floor platform, ECAS system, panoramic view, comfortable
riding and rich equipment options such as Wi-Fi and camera surveillance system.
Karsan offers ATAK to meet your expectations from a Public Transportation vehicle.
Ideal Public
Transportation
Vehicle
ATAK is the contemporary, comfortable and safe public
transportation vehicle with its eye-catching features such as high
passenger capacity, wheelchair accessible low floor design, front
independent suspensions and rear engine which provides fuel
economy, performance and a silent trip.
Contemporary
Low Floor Design
ATAK, offers easy getting on and off opportunities to passengers with its
low floor design. There are no steps or any other obstacles through the
corridor which is between the entrance and exit service doors. This feature
provides freedom for mobility inside the vehicle. Also, ATAK has both ECAS
and Kneeling functions.
Wheelchair
Accessibility
ATAK is a class-leading vehicle in wheelchair accessibility which is a strong
part of the modern city life. Mobility for freedom is offered to everyone by
its wheelchair accessibility feature. Through its foldable ramp, ATAK offers
easy getting on and off opportunities to passengers with wheelchairs.
Safe and
Comfortable
Driving Pleasure
Wide driving view and optional isolated driver’s cabin (cockpit) provides safe
driving. The dashboard and the cluster which are especially designed for
ATAK offer maximised driving comfort even under heavy traffic conditions.
High Level Safety
Technology
High Level EBS Functions
The functions of EBS are implemented in the central control unit (ECU). Some of the functions are only optional, and can be enabled or disabled by
EoL programming. The main EBS functions are the following:
EBC
ABS
ATC
Electronic Brake Force Control “EBC”
The driver’s demand for retardation is recorded and converted into
braking pressures taking into account the axle load in such a way that
the demanded retardation versus brake pedal position characteristic
is independent from the load condition of the vehicle. The brake pedal
characteristic can be adjusted by EoL parameters.
DTC
Unlockable “ABS”
The target of ABS function is to prevent wheel lock up during braking
to maintain the steering and stability of the vehicle and to minimize
the stopping distance. The ABS intervenes during braking whenever
the available friction between the road and the tire of a monitored
wheel is less than the braking force applied to the wheel causing the
wheel to decelerate (impending wheel locking) quickly.
BA
No Spinning with “ATC”
The target of the ATC function (Automatic Traction Control) is to avoid
the spinning of the driven wheels in order to keep the vehicle stability
during driving and to increase the traction force during acceleration.
ATC can be divided in two sub-functions: Engine Control and Brake
Control.
Anti-Frictional “DTC”
The target of DTC function (Drag Torque Control) is to avoid the
locking tendency of the driven wheels caused by engine inertia on
low friction surface. If the average speed of the driven wheels indicates
locking because of the low friction, DTC requests a certain amount of
engine torque to get the driven wheels rolling.
It is possible to use a lining wear switch instead of lining wear sensor
for the pad wear warning, but in this case EBS cannot measure the
pad wear, and is not able to synchronize it between the axles.
RI
Like a First Aid Kit “Brake Assistant”
Based on experiences, the drivers pedal movement is fast enough only
in the beginning of an emergency braking and the brakes are not applied
fully. The target of this function is to aid the driver in such a situation, saving
valuable time in the first, high-speed period of the emergency braking.
Based on the drivers brake demand and the speed of the brake pedal
actuation, the brake pressure will be increased compared to the original
drivers demand.
LWDC Lining Wear Display and Control
Lining wear sensors can be connected directly to the modulators
(EPM) close to the axles. EPM reads the sensor value and sends the
information to the central ECU. The ECU presents the lining wear
values on CANBUS (to make it available on the instrument cluster
for the driver), and also for diagnostic purposes. Additional EBS can
take into consideration the measured sensor values in the brake
control in such a way that it modifies brake force distribution in
order to synchronize the wear between the axles. In case of critical
pad wear, EBS will warn of pad change.
Retarder Integration
The task of the function is to reduce the load of friction brakes
replacing the braking force with the actuation of auxiliary brakes.
The auxiliary brakes (which can be an engine controlled endurance
brake, and primary or secondary retarder) are activated automatically
by the EBS if the brake pedal is applied.
The retarder integration function does not change the compatibility
between the towing and towed vehicle (the retarder contributes to
the braking of both towing and towed vehicles).
CFC
Coupling Force Control
The target of the Coupling Force Control function is the distribution
of brake energy between the towing and towed vehicle. The output
of the function is a pressure difference which modifies the pressure
of the trailer coupling head.
BSBF Bus Stop Brake (Door Brake) Function
The Door brake function is developed especially for city bus
applications. The target of the function is to provide the driver with a
way holding the vehicle at a standstill while the engine is still running
without using the foot brake or parking brake.
DLI
Differential Lock Inhibit
The power supply to the differential lock switch has to come from
EBS. EBS checks the speed difference between the drive wheels
and if the speed difference is over a certain limit, EBS prohibits the
engagement request to protect the differential lock against damage.
HSA
Hill-Holder “Hill Start Aid”
The Hill Start Aid function is used to simplify starting on up-hill slopes
by holding the service brake pressure or delaying the service brake
release in order to give the driver extra time for the manoeuvring
of the pedals. The function is not intended to be used as a parking
brake.
SAC
Software Anti-Compound
If the parking brake active signal is available, EBS will limit the
pressure on the axle with spring brake chambers if the parking
brake is engaged.
DID
Driver Information and Diagnostic
The warning and information displays are different for the different
applications; it depends on the vehicle electric system. The main
communication interface of EBS for display and warnings is
the CANBUS communication line which is also the interface for
diagnostic (KWP over CAN). However there is the possibility to
control some lamps directly from the EBS ECU.
Corrosion
Prevention
ATAK offers a Stainless Steel body as an option. Having this
manufacturing solution, ATAK provides low maintenance costs and
more durability against corrosion.
Fuel Economy
and High
Performance
ATAK has a powerful and environmental friendly Euro VI engine which
provides great fuel economy. Both a comfortable trip and high performance
are guaranteed with its silent and hard-working engine.
