Automatic Advanced Emergence Braking System and Parking System

Published on Sep 03, 2023


“EMERGENCY BRAKING SYSTEM” is nothing but one of the breaking system in automobile at the time of emergency. In this breaking system pneumatically operated one. Here the additional pneumatic cylinder and Emergency Button is provided in the automobile itself.

In this project, the push button is used to activate/deactivate the solenoid valve. The switch is ‘ON’ at the time of emergency; the solenoid valve is activated, so that the compressed goes to the pneumatic cylinder.

Then the compressed air passes through the tube, and then pushes the pneumatic cylinder, so that the braking is applied at the time of button in “ON” position (i.e.-Emergency time).

The speed of the pneumatic cylinder is varied by using flow control valve. This is the way of controlling braking speed of the vehicle at the time of emergency. In our project, we have to apply this braking system in one wheel as a modal.


In most of the garages the vehicles are braking by using ordinary braking system. In the case of emergency (hart attack, unconscious) time, driver doesn’t apply brake by leg. In that time, driver is only ON the button in the electronic control unit. This control unit is fitted, near the driver. In order to avoid all such disadvantages, this parking braking system has been designed in such a way that it can be used to break the vehicle very smoothly without any impact force. The operation is made be simple that even any person can handled, by just pressing the button.


Emergence Braking System


Emergence Braking System


The Ignition Key is fixed in near of the driving persons in the four wheeler. The air tank contains the compressed air already filled. The switch was ON at the time of emergency, the solenoid valve was activated. The solenoid valve stem is open, the compressed air flow from the air tank to the flow control valve.

The compressed air flow is controlled by the valve is called “FLOW CONTROL VALVE”. This air flow is already set. Then the compressed air goes to the pneumatic cylinder. The pneumatic cylinder piston moves forward at the time of compressed air inlet to the cylinder.

The pneumatic cylinder moves towards the braking arrangement. Then the braking liver is activated, so that the vehicle stops. Then the pneumatic cylinder piston moves backward.


1) Brake cost will be less.

2) Free from wear adjustment.

3) Less power consumption

4) Less skill technicians is sufficient to operate.

5) Installation is simplified very much.


1. Need separate air tank

2. This system applied in the case of emergency period only.

3. Addition cost is required to install this system to four wheeler.


 Four wheeler application

 It is also implemented in two wheeler.
