An overview of the drive by wire technology is presented along with in-depth coverage of salient drive by systems such as throttle-by-wire, brake-by-wire, and steer-by-wire systems, and hybrid-electric propulsion. A review of drive by wire system benefits in performance enhancements and vehicle active safety is then discussed. This is followed by in-depth coverage of technological challenges that must be overcome before drive-by-wire systems can be production ready. Current state of the art of possible solutions to these technological hurdles is then discussed. Future trends in the drive-by-wire systems and economic and commercialization aspects of these system are presented at the conclusion of the chapter.

3. INTRODUCTION
•The development of electronic control
systems is nowhere more apparent than in
the modern automobile.
•The benefits of applying electronic
technology are clear improved
performance, safety, and reliability with
Reduced manufacturing and operating
costs.
•Drive-by-wire is a catch-all term that can
refer to a number of electronic systems that
take the place of old mechanical controls.
Instead of using cables, hydraulic pressure.

4. HISTORY
1990s.That technology, just like drive-by wire, uses electrical wires to control the
normal operations of a plane. There is a trend in the automotive industry towards
eliminating mechanical and hydraulic control systems and replacing them with
electronic controls.
1995-BMW technique began working on the project Z 22 TO CHANGE carbon
fibre structure to drive by wire .
• 1998-aircraft technology using computerised joystick .
• 2002-HY WIRE car by general motors .
•2009-Wire “de assault systems solid works” releases.
•2010-introduces sensors for the paddle

5. TYPES OF DRIVE-BY-WIRE SYSTEMS

6. STEER- BY -WIRE
In vehicles that are equipped with steer-by-wire technology,
there is no physical connection between the steering wheel
and the tires.

7. HOW DOES IT WORK?

8. THROTTLE-BY-WIRE
•Throttle-by-wire is an automotive technology
that is widely used on vehicles today.
•Throttle-by-wire, was the first type of drive-
by-wire system introduced. These systems use
a pedal unit and an engine management
system.

9. HOW DOES IT WORK?
The pedal uses sensors that measure how much or how little the driver moves
the accelerator

10. BRAKE BY WIRE

11. Advantages Of Brake-by-wire
1. Reacts more quickly resulting in shorter stopping distance
and time.
2. Loss of mechanical systems results in noiseless operation
and elimination of vibration.
3. Lesser space consumed making the engine compartment
and compact and helping in better space utilization.
4. Allows the ECM to integrate torque management with
cruise control, traction control and stability control.

12. By replacing conventional throttle systems, drive-by-wire systems can
significantly reduce the number of moving parts in a vehicle. This reduces
weight, increases operational accuracy and stretches out the time between
service visits for things like mechanical maintenance and other adjustments.
BENEFITS OF DRIVE-BY-WIRE
SYSTEMS

13. THE FUTURE OF DRIVE-BY-WIRE
The removal of mechanical controls could allow
automakers to design vehicles that are radically
different from the cars and trucks that are on the road
today. Concept cars like the By-Wire have even
allowed the seating configuration to be moved
around, since
