SBC(SENSOTRONIC BRAKE

CONTROL)

WHAT IS SBC? Sensotronic Brake Control (SBC) is an electro-hydraulic

brake system. SBC allows high pressure and dynamic brake pressure

individual control for each wheel. Mercedes-Benz first introduced the Sensotronic Brake

Control (SBC)system on their SL-Class sports car.

Unlike conventional braking system SBC dispense with mechanical hydraulic coupling with pedal and brake.

Superb directional stability and optimally assured brake distance are the result of SBC.

SBC allows precise braking and increased vehicle stability.

CENTRAL CONTROL UNIT OF SBCVarious component of central control unit of SBC

Pump motor High pressure reservoir Hydraulic valve Pressure sensor SBC micro computer

For optimal controlling SBC micro computer is also connected to electronic stability program(ESP).

Control unit use various sensors to record motion of vehicle.

WORKINGBrake pedal

(SENSOR record pedal travel)

SBC system record pressure in master cylender and send command to ESP

Control unit determine brake pressure for each wheel

Hydraulic valve create pressure with energy of high pressure reservoir

Electric pump generate required pressure as monitored by pressure sensor

Pressure sensor measure applied pressure and regulate brake oil to each wheel by hydraulic valve

FEATURES OF SENSOTRONIC BRAKE CONTROL SYSTEM

Emergency Braking- SBC recognizes the driver’s rapid movement from the accelerator onto the brake pedal as a clue to an imminent emergency stop and responds automatically

Driving Stability-When there is a risk of swerving, the system interacts with the Electronic Stability Program (ESP) which keeps the vehicle safely on course through precise braking impulses at all wheels.

Comfort- SBC serve to increase brake comfort particularly during sharp deceleration.

Soft-Stop-The Soft-Stop function of the SBC software ensures particularly gentle and smooth stopping during heavy traffic jams.

On a wet road surface the system metes out short brake impulses at regular intervals to ensure that the water film on the brake discs dries off and that SBC can always operate with optimum effectiveness.

On hills or steep drives the Sensotronic Brake Control Drive-Away Assist prevents the car from rolling backwards or forwards

ADVANTAGES OF SBC

Fast build up of brake pressure. Optimum brake power distribution.

No pedal vibration during ABS operation. Skidding in corners is avoided.

Stopping distance is reduced by up to 3%.

CONCLUSION

 Conclusion Sensotronic Brake Control is the brake of the future. The interdisciplinary interaction of mechanics and electronics provides its greatest

benefits – the microcomputer, software, sensors, valves and electric pump work

together and allow totally novel, highly dynamic brake management.
