HISTROY OF SBC

• Robert Bosch has played a role in many
  innovations.
• This include the first electronically controlled
  antilock brakeing system (ABS) in 1978, the
  traction control system (TCS) in 1987, and the
  mass production of Electronic stability program
  (ESP) in 1995.
• The company also helped Mercedes-Benz develop the
  most technologically advanced system in
  production the electro hydrolic rake(EHB)also
  known as SENSONTRONIC BRAKE CONTROL(SBC)

Working of BRAKE

• We step on brake pedal.
• The plunger is pushed into the master cylinder.
• Hydrolic fluid is forced through a series of
  tubes to the breaking units.
• Brake shoe in drum brake and caipers in disk
  brake are pushed aginst dru and piston, causing
  wheel to stop.

What is brake control system ?

• Portable devices for preventing unwanted movement
  of vehicles, and It is used for slowing or
  stopping a moving vehicle, wheel, axle, or to
  prevent its motion, most often accomplished by
  means of friction, to prevent or restrain its
  movement called brakes.
• brake band - a band that can be tightened around
  a shaft to stop its rotation.
• A brake controller is an electronic device that
  regulates the electric trailer brakes(electric
  friction brake). It allows the driver to activate
  and monitor trailer brake activity from the cab
  of the vehicle.

What is SENSOTRONIC BRAKE CONTROL?

• Sensotronic Brake Control is an innovative
  electronically controlled brake system that is
  faster and more precise then the conventional
  breaking system
• With sensotronic brake control system electric
  signals are used to pass the drivers braking
  commands onto a microcomputer which process
  various sensor signals simultaneously and,
  depending on the particular driving situation,
  calculates the optimum brake pressure for each
  wheel.

Difference between sensotronic and conventional
brake control
SENSOTRONIC BRAKE CONTROL CONVENTIONAL BRAKE CONTROL
The system employs a travel sensor and a pressure sensor at the pedal to measure the speed and force of the driver's command. The control unit processes this information and generates the control signals for the wheel pressure modulators. Normally, the master brake cylinder is detached from the brake circuit. Conventional brakes consist of a basic hydraulic system which sends fluid to each wheel when the brake pedal is applied. This system utilizes a combination of mechanical components to increase the force on the drums or rotors when you press the brake pedal to activate the brakes, bringing the vehicle to a stop.

COMPONENTS AND FEATUERS OF SBC

• MICROCOMPUTER-This system calculates the braking
  force for each wheel individually.
• HIGH PRESSURE ACCUMULATOR-High pressure
  accumulator contains the brake fulid which flows
  into the system
• HYDROLIC UNIT-They meter the brake pressure
  accordings to requirements and pass it to the
  brakes.
• WHEEL SPEED SENSOR-Generating signals
  representative of the wheel-speed
• EMERGENCY BRAKING-Recoginzes the drivers rapid
  movment from the accelerator onto the brake
  pedal.
• COMFORTS-Provides comfort particularly during
  sharp deceleration or when the anti-lock braking
  system is operational.
• BRAKING IN CORNERS-SBC offers the possibility of
  assigning brake force in way appropriste to the
  situation.

FUTURE APPLICATIONS

• The advent of electronics in brake technology
  opens up new and promising opportunities in the
  disciplines of safety and comfort.By means of SBC
  we have also moved a considerable way closer to
  the realization of long-term objective,namely to
  be able to automatically guide the cars of the
  future along the roads with the aid of video
  cameras,proximity rador and advanced telematics.
• Its already plan to implement in upcoming cars

10
DEMERITS OF SBC

• COST-increases due to electronic components.
• ASSEMBLING-slight complex assembling.
• DIFFICULT FOR MAINTENANCE-prone to environment
  conditions.

11
conclusion

• With reference to the advantage and disadvantage
  it is concluded that the place of conventional
  brake system in the future.
• One of the most disadvantage that is its higher
  cost due to the electronic components will get
  reduced after the adaptation of this system by
  all automobile companies. Also the maintenance of
  the electronics component will be easy when we
  shall get familiar with this system
