Vehicle with hybrid power system and the control method thereof

Abstract

This invention discloses a vehicle with a hybrid power system, comprising multiple power units, each including at least an engine and a motor drive / generator, constituting a hybrid vehicle. The motor drive / generator has two modes: drive and power generation. In drive mode, it provides additional mechanical energy to provide sufficient torque or speed as needed; conversely, in power generation mode, it charges the battery and reduces mechanical energy to decrease torque or speed as needed, increasing maneuverability. The multiple power units can operate independently to control the trajectory. The vehicle of this invention includes, but is not limited to, aircraft, surface vehicles, underwater vehicles, and ground vehicles.
