Designing and prototyping an automated motorcycle speed limiter using a microcontroller acting as an engine control unit (ecu)
The general objective of this thesis was to design and to prototype an Automated Speed Limiter system in a motorcycle with Arduino as its controller. With the high number of speed related crashes it was hoped that this system will be able to limit the speed of motorcycle when needed. A mechatronics clutch was developed for drive switching mechanism. Arduino based controller was developed, the system was also equipped with Hall Effect based speed detection sensor, Engine Capacitive Pickup RPM sensing, and Xbee based radio communication. The electronic aspects of the system include an onboard voltage regulator, a signal conditioning circuit, and logic circuit to control the mechatronics clutch. The result of this thesis was an automated speed limiter system that capable of limiting the speed of a motorcycle, by retaining the throttle system when a speed limit signal was detected. Further development and studies includes elimination of Electromagnetic Interference and Radio Frequency Interference, better mechanical design, and possibilities of embedded vision technology.
