Ecway Technologies provides engineering projects and software development services out of multiple offices in India. They specialize in automatic clutch and braking systems for vehicles using microcontrollers. The system uses IR sensors to detect interruptions, a microcontroller for control based on programmed instructions, and relays connected to DC motors to automatically engage the clutch and brakes. The advantages are simple maintenance, improved safety, and low cost, while the disadvantages are higher initial costs and needing an air tank.

AUTOMATIC CLUTCH & BRAKING SYSTEM
ABSTRACT
This project is used to protect the car from accident or interrupt the compare
ness of driving a car. The figure shows the Functional Diagram of Automatic
Clutch and braking system implementing by Micrcontroller.
It’s consists of
Interrupt sensor, controlling unit and main part of Micro controller.
IR sensor is used to detect the interrupt the car is sensed through IR sensor,
its called optical sensor.
The interrupt sensing output is send to the Micro
controller. Micro controller is a general-purpose device and is used for control
purpose using a fixed program that is stored in EPROM. The Micro controller
design uses a much more limited set of single byte and double byte instructions
that set of single byte and double byte instructions that are used to move data and
code from internal memory to ALU.

2. Micro controller reads the status of input and takes decision according to the
Assembly Language program stored in Micro controller. The output from the
controller is fed to a relay driver, which can be used to drive the relays, due to
energize, and de energize of relays. The DC motor is connected with this relay is
getting On/Off for motor rotate forward and reverse direction to control the clutch
and brake mechanism. Thus we can automatically control the clutch and brake by
using Micro controller.
