2. WHATIS AUTOTRONICS??????
Auto-tronics is the combination of automobile
and electronics while hybrid refers to
technology that uses two or more distinct
power sources to move the vehicle.

3. AUTOTRONICS IN A VIEW

4. INTRODUCTION TO AUTOTRONICS
• AUTOTRONICS=AUTOMOBILE+ELECTRONICS
• First electronic part in an automobile was called an ECU
(ENGINE CONTROL UNIT)
• Analysts estimate that more than 80
percent of all automotive innovation now
stems from electronics.

5. HISTORY:
• The first electronic part in an automobile was called an “Engine control unit” as it is named later
as “Electronic Control Unit”.
• 1970’s:Introduction of electronics for engine controls
• 1980’s:anti-lock braking introduction
• Early 1990’s:Airbags become standard
• Late 1990’s: Rapid expansion of body electronics-seat motor’s, computers, instrument panel
lighting, auto locking systems and keyless entry
• Early’s 2000’s to date: infotainment, including sophisticated audio and video: Signals sent via
satellite(such as the on star system):GPS and mapping Capabilities : satellite radio
• Late 2000’s: steer-by-wire, wireless connectivity

6. AUTOMOBILE APPLICATION OF AUTOTRONICS IN
FOLLOWING DOMAINS:
• Braking system
• Steering system
• Suspension system
• Transmission system
• Engine(fuel intake)

7. BRAKING SYSTEM
• EBS increases traffic safety through
reduced stopping distance and improvedbrake stability.
Functions In ECB:
 Anti-lock braking system (ABS):
 Traction control system (TCS)
 Brake lining wear control

8. ABS:
 ABS is an acronym for anti-lock braking system. First developed and
patented in 1936, ABS is actually derived from the German term "anti
blockier system."
 Anti-lock brakes are designed to prevent skidding and help drivers
maintain steering control during an emergency stopping situation
 Difference between ABS & Traction Control
 ABS
manage the grip of the tires for braking maneuver
 Traction Control
manage the grip of the tires for accelerating maneuver

9. STEERING SYSTEM
• The self-alignment estimation control uses both the EPS sensor
information and internally programmed EPS control
• Speed sensitive steering system:
Speed sensitive steering system is used to control the power
steering pump pressure in relation to vehicle speed.
Below 10mph (16km/h) the computer operates the steering
This action reduces the steering effort during low speed maneuver and
parking.

10.  Electrically powered steering
uses an electric motor to drive
either the power steering
hydraulic pump or the steering
directly.
 steering sensor" is located
on the input shaft where
it enters the gearbox housing.
 An interface circuit that
same housing converts the
signals from the torque sensor and rotation sensor into signals.
 Sensors
 Accelerating sensor ,displacement sensors, Steering wheel position

11. TRANSMISSION SYSTEM
• Mainly it controls the shifting process of the gears.
• Electronically controlled transmissions were introduced on BMW
• products in 1986 on 5 and7 series vehicles.
• The TCM also adapts to changing conditions within the transmission
• by monitoring slip ratios .
• The TCM controls the operation of the Lock-Up Torque Converter
which further increases economy
 ADVANTAGES:
• Increased fuel economy
• Improved shift comfort
• Increased driving safety

12. ELECTRONIC FUEL INJECTION
• EFI system electronically meters the fuel so that the
exact amount needed is provided to the engine.
• EFI uses to fuel to power theengine by pumping it forcibly
by using high pressure through a small nozzle or valve.
• A high-pressure fuel pump that produces high fuel
pressures (5 to 12 MPa

13. ADAPTIVE CRUISE CONTROL
• It automatically adjusts the vehicle speed and distance to
that of a target vehicle.
• ACC uses a long range radar sensor to detect a target
vehicle up to 200 meters in front of vehicle.
• As per standard cruise control
the driver can override the system at any time.
• Another advantage of this system is that the driver will not exceed the
speed limit on the highway.

14. AIRBAGS…
The air bag technology is based on electronic sensors that measure the
amount of quick deceleration through an accelerometer
 The new calculations will take into account the position of the seats, the use
of a seat belt and the weight of the occupants

15. LATEST RESEARCH
•  Active bumper system,
•  active hood lift system,
•  vehicle to vehicle communication
•  Global Positioning System
•  Rain sensing wipers
•  Adaptive light system
