Sensotronic Brake Control (SBC) is an electro-hydraulic braking system introduced by Mercedes-Benz that allows for individual brake pressure control of each wheel. SBC uses a central control unit connected to sensors and valves to determine the optimal brake pressure for each wheel based on inputs like pedal position, vehicle motion, and inputs from the Electronic Stability Program. This precise control of brake pressure for each wheel provides benefits like reduced stopping distances, improved stability, and comfort features like soft stops and drive-away assist.

(SENSOTRONIC BRAKE CONTROL)

2. 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.

3.  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.

4. CENTRAL CONTROL UNIT OF SBC
Various component of central control unit of SBC
 Pump motor
 High pressure reservoir
 Hydraulic valve
 Pressure sensor
 SBC micro computer

5.  For optimal controlling SBC micro computer is also
connected to electronic stability program(ESP).
 Control unit use various sensors to record motion of
vehicle.

6. WORKING
Brake 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

7. 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

8.  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.

9.  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.

10.  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

11. 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%.

12. 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.
