Designing control system for hybrid motorcycle

Abstract

The article presents a type of hybrid motorcycle improved from a used scooter Attila 2002. The author has used microcontroller to control a DC electric motor with the power of 400W that works in collaboration with the gasoline engine and the torque transmitted to the rear wheels of the vehicle. Each of two 12V-14Ah battery connected in series will supply power to the electric motor. These two are always charged by the generator of the vehicle when the gas engine operates. During accumulator’s charging operation, current is provided to the control system and electric motor is always checked by microcontrollers and processors in order to protect the accumulator as well as to make sure the entire system is not damaged. After designing and manufacturing the control system, the author has put it into the actual test. The results showed that the device worked safely and met all the requirements. Through the test compared with mode with only the gas engine, fuel costs decreased by 10% to 18%, HC density decreased by 18% to 50%, the concentration of CO decreased by 10% to 40%, which depend on different speed mode.
