This document discusses how automotive electronics, or autotronics, improve vehicle performance. It begins with an introduction defining autotronics as the combination of automobiles and electronics. It then discusses several vehicle systems assisted by autotronics, including braking, steering, transmission, and fuel injection. For each system, it provides details on the electronic components that help control and optimize performance, such as ABS and traction control for braking. The document concludes that modern vehicles contain numerous electronic control units and that continued innovation in automotive electronics will further improve vehicle performance.

2. INTRODUCTION
 AUTOTRONICS = AUTOMOBILE + ELCTRONICS
 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.
AUTOMOBILES APPLICATIONS OF AUTOTRONICS
 Braking system
 Steering system
 Transmission system
 Electronic fuel injection system

3. BRAKING SYSTEM
 EBS increases traffic safety
through reduced stopping
distance and improved brake
stability.
Function In EBS
 Anti – lock braking system.
designed to prevent skidding
and maintain steering control
during an emergency stopping
situation .
 Traction control system(TCS).
 Brake lining wear control

4. STEERING SYSTEM
• Electrically powered steering uses an electric motor to
drive the either the power steering hydraulic pump or the
steering directly.
Steering sensor
Located
on Input shaft
Interface circuit
Torque sensor &
Rotational sensor
Steering signal

5. TRANSMISSION SYSTEM
• Mainly it controls the shifting process of the gear.
• Were introduce on BMW product in 1986.
• The TCS control the operation of the lock up torque
converter , which further increase economy.
ADVANTAGES
Increased fuel economy.
Comfort shifting of gear.
Increased driving safety

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

7. LATEST RESEARCH
 Rain sensing wipers.
 Adoptive light system
 Vehicle to vehicle communication.
 Global positioning system.
 Air bag system(Based on electronic sensor that uses
amount of quick deceleration through an
accelerometer)

8. CONCLUSION
 A modern car may have up to 100 electronic
control units and a commercial vehicle up to 40. With
brilliant minds working in the auto industry, there are
limitless possibilities to what the manufacturers will
include in their products in the coming years.
Improving performance is a
standard not an option
