  1. VELOCITY CONTROL OF MOTORBIKE USING PIC BY N.KATHIRAVAN P.ARUN KUMAR GOVERNMENT COLLEGE OF ENGG. TIRUNELVELI - 07.

  2. 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.

  3. 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.

  4. ACCIDENTS HAPPENED DURING THE YEAR 1991-2000

  5. SURVEY BY MINISTRY OF ROAD AND TRANSPORT .

  6. 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.

  7. OVERALL BLOCK DIAGRAM .

  8. MAJOR COMPONENTS • FM Transmitter • FM Receiver • Speed monitoring unit (Digital speedometer) • Speed controlling Unit (PIC Microcontroller)

  9. ADVANTAGES OF FM • Better noise immunity • Efficiency of transmission is High • Rejects interfering signals (Capture Effect). • Improved noise performance.

  10. 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

  11. DIGITAL SPEEDOMETER

  12. ONLY 35 INSTRUCTIONS DATA MEMORY (368 BYTES) FLASH PROGRAM MEMORY(8KB) 10 BIT A/D MODULE 2 ANALOG COMPARATOR FEATURES OF PIC

  13. SPEED CONTROL UNIT

  14. 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.

  15. FLOW CHART FOR OVERALL OPERATION

  16. OVERALL OPERATION

  17. 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.

  18. 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.

  19. REFERENCES • “Electronics for you- January 2005” for Digital Speedometer. • “ The PIC Hand book” by Mike Predo, TMH publications. • “Programming PIC with Mbasic and Emedded C” by John F.Wester.
