Active safety system ppt

1. ACTIVE SAFETY
SYSTEM

2. INTRODUCTION
• An active safety system works to prevent an accident. These system
always stay active while you drive and continuously work to keep you
from getting into an accident. Most active safety features are electronics
and controlled by a computer. They include traction control, electronic
stability control and braking systems. These also include advanced driver
assist systems that use sensors such as forward collision warning and
lane departure warning, along with adaptive cruise control.

3. ELECTRONIC STABILITY CONTROL
(ESC)
• ESC system improves vehicles
stability by detecting and reducing
loss of traction (skidding). This
system prevents crashes by
reducing the danger of vehicle
skidding or driver losing control as
a result of over steering. This
system becomes active when a
driver losses control of his or her
car.

4. ADAPTIVE CRUISE CONTROL
(ACC)
• ACC is an intelligent form of
cruise control that slows down
and speeds up automatically to
maintain a safe distance from the
vehicles ahead. The control is
based on sensor information
from on-board sensors.

5. LANE DEPARTURE WARNING
(LDW)
• LDW system is a mechanism
designed to warn a driver
when the vehicle begins to
move out of its lane on
freeways and arterial roads.
These systems are designed
to minimize accidents by
addressing causes of
collisions such as driver error,
distractions, and drowsiness.

6. DRIVER MONITORING
(DM)
• This safety system uses infrared
sensors to monitor driver
attentiveness. Specifically a driver
monitoring system includes a
closed-circuit camera (CCD) camera
placed on the steering column that is
capable of eye tracking via infrared
Light-Emitting diode (LED) detectors.
If the driver is not paying attention to
the road ahead and a collision is
eminent, the system flashes lights
and warning sounds for the driver.

7. NIGHT VISION SYSTEM
(NVS)
• NVS extend the perception of the driver beyond the limited reach of headlights through the use of
thermo graphic cameras, infrared lights, heads up displays, and other technologies to prevent
accidents.

8. AUTOMATIC EMERGENCY BRAKING
(AEB)
• This system slows the vehicle and potentially reduces collision severity in an unavoidable
situation. If the drivers braking is not enough to avoid a collision , autonomous emergency
braking applies maximum brake pressure to reduce speed and impact speed and impact of
collision.

9. ROAD SIGN RECOGNITION
(RSR)
• Road sign recognition notifies and warns the
driver of enforced restrictions on the road.

10. ANTI-LOCK BRAKING SYSTEM
(ABS)
• ABS allows the wheels on a motor vehicle to maintain tractive contact with the road surface
based on the driver inputs while braking. This prevents the wheels from locking up (ceasing
rotation) and avoids uncontrolled skidding. This automated system works on the principles of
threshold braking and cadence braking.

11. BLIND SPOT DETECTION
(BSD)
• Blind spots are areas outside of a vehicle that the driver is unable to see. These can be caused
by window pillars, headrests, back seat passengers, and other objects. A BSD system is a
vehicle-based sensor device that detects other vehicles located to the drivers side and rear.

12. TYRE-PRESSURE MONITORING SYSTEM
(TPMS)
• TPMS is an electronic system designed to monitor air pressure inside pneumatic tires on various
types of vehicles. TPMS report real-time tyre-pressure information to the driver of the vehicle,
either via a gauge, a pictogram display, or a simple low-pressure warning light.

14. CONCLUSION
• This active safety is not only for cars this system is also used in trucks like volvo, BharatBenz
etc… and also for heavy vehicles.
• These forward-looking technologies are expected to play an increasing role in collision avoidance
and mitigation in the future. Most major component suppliers, such as Aptiy, TRW and Bosch, are
developing such systems.
