and conveniences than other braking methods, vacuum boosters brake systems were
manufactured by several companies in series with mechanical drum brake.
It is mounted intermediate on the master cylinder & brake lever and minimizes
driver’s effort in braking. There twice spaces with movable rubber diaphragm built
in a hollow frame.
To minimize the brake lever force, push rod servo vacuum booster with master
cylinder is mechanically fabricated so as to increase the brake hydraulic pressure.
Due to this high hydraulic pressure, less effort is enough in brake lever. The booster
normally uses vacuum from the engine to increase the pressure on the accelerator.
Braking is ineffective and difficult in conventional break systems during unexpected
shut down of the automobile engine. While the booster open its air valve to move the
master cylinder to the front automatically to manage dynamic stability in controlling
the speed of the automobile.
A new electronic brake booster and precise pressure control method for technical
engineering were discussed by Wua et al. [2] and the weaknesses in active braking for
smart driving of existing braking systems is addressed. Those results illustrated the
optimal performance of pressure, acceleration, and speed control. Mosayebi et al. [3]
described the importance of designing and optimizing braking systems for various
vehicles. The vacuum brake device, as with the air brake, is regulated or operated
through a brake tube, as was described by Ugale et al. [4]. Muenchhof et al. [5]
have designed a model that measures the vacuum chamber pressure and working
chamber pressure of the vacuum brake booster. Anbalagan et al. [6] modified the
vacuum braking system in light and heavy cars and the same has been tested for
implementation. The brake pedal was designed by Mangukia et al. [7] to provide the
necessary leverage and pressure to touch the four wheels.
A simulation model with Lab VIEW is developed for this work to monitor and
validate the performance of the vacuum booster based on real-time PID speed control
action. If the validated booster fulfills the required measurements which have been
designed in the simulation model, it will be separated as effective without defects
for further processing. In Lab VIEW software, the validated plot for the particular
vacuum booster is obtained. Therefore, real effect of braking test based on PID action
and validation by Lab VIEW simulation model for servo vacuum booster enables a
healthy servo vacuum booster to be achieved.

Verification
In order to get the real effect of braking, the brake lever action is simulated as that of
PID action for controlling the speed. Since PID action is similar to that of braking
action, it is well suited for this application of testing.
The PID speed control operation by the brake lever as actuator is denoted by the
formula
