Hybrid motorcycle drive control method {METHOD OF DRIVE CONTROL FOR HYBRID MOTORCYCLE}

The present invention relates to a drive control method of a hybrid motorcycle, and more particularly, to a drive control method of a new concept hybrid motorcycle in which the engine power is used for charging a battery and is driven only by motor power.

In general, motorcycles are used for physical transport purposes such as mail delivery, food delivery, goods delivery, or human transportation purposes such as commuting.

Conventional motorcycles have used an internal combustion engine as a power source, especially a two-cycle gasoline engine. The two-cycle gasoline engine makes it easy for the motorcycle to climb steep hills due to its large power and torque.

However, since the gasoline engine emits exhaust gas and generates a loud noise from the engine during acceleration, there is a limit that is unsuitable for use in residential areas such as apartments and residential areas, or in densely populated areas. That is, the conventional motorcycle has an inherent limit that causes air pollution and noise generation.

Recently, in order to solve this problem, a hybrid motorcycle to which a power conversion mechanism is applied through drive conversion of both an internal combustion engine and an electric motor (motor wheel is generally applied) has been developed.
