  INTRODUCTION •The development ofelectronic 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.

  HISTORY 1990s.That technology, justlike 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

  TYPES OF DRIVE-BY-WIRESYSTEMS
• 6.
  STEER- BY -WIRE Invehicles that are equipped with steer-by-wire technology, there is no physical connection between the steering wheel and the tires.

  HOW DOES ITWORK?

  THROTTLE-BY-WIRE •Throttle-by-wire is anautomotive 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 ITWORK? The pedal uses sensors that measure how much or how little the driver moves the accelerator

  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.

  By replacing conventionalthrottle 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 OFDRIVE-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
