VELOCITY CONTROL OF MOTORBIKE USING PIC BY N.KATHIRAVAN P.ARUN KUMAR GOVERNMENT COLLEGE OF ENGG. TIRUNELVELI - 07.
OVERVIEW One of the main reason for accident -Over speed This paper deals with controlling of speed automatically in two wheelers in SLA’s. This is done with the help of PIC( Peripheral Interface Controller ) and FM. By implementing this system, the speed of motor bike reduces to 40km/hr when entering into Speed Limited Areas (SLA). So, accidents are reduced to some extent.
INTRODUCTION • According to the survey in India, every year 3,00,000 accidents were reported. • Studies reveals that- 77% due to improper driving (Over speed). • Analysis shows that- 80% due to Human error. • So, minority of accidents only due to bad roads & weather.
WHY THESE ACCIDENTS ARE INCREASING EVERY YEAR • Over speed of vehicle at • Speed Limit areas • During Overtaking • Improper of Land discipline, • Lack of space when driving, • Jumping of signals.
MAJOR COMPONENTS • FM Transmitter • FM Receiver • Speed monitoring unit (Digital speedometer) • Speed controlling Unit (PIC Microcontroller)
ADVANTAGES OF FM • Better noise immunity • Efficiency of transmission is High • Rejects interfering signals (Capture Effect). • Improved noise performance.
SPEED MONITORING UNIT • In analog speedometer Speed ~ eddy current in rotating disc. • Lack in accuracy and precision. • It is replaced by digital speedometer. • It comprises of • Transducer • Mechanical unit • Digital Display

FUNCTION • Microcontroller feds the control signal to gate terminal of TRIAC • It varies the ON & OFF cycle of TRIAC. • By varying the i/p to gate, the voltage of Spark plug is controlled. • Thus, output torque of an engine is controlled, in turn the speed reduced.
THE LAST WORDS….., This is one time investment and cost is also affordable to everyone. • This system makes the user to follow the rules in polite way. • It reduces the accidents due to over speed And allowing the safe drive.
RECOGNITION • This concept was inspired by Mr.M.Raja, Systems Engineer, Robert Bosch India Ltd., and guided us to do this project. • We express our gratitude to Mr.SelwinRajadurai, Lecturer, Dept. of Mechanical Engg., GCE-Thirunelveli for his consistent helps and efforts for the success of this project.
