Abstract
The present invention discloses a power transmission system and a vehicle having same. The power transmission system includes: a power source; a speed change unit; a first motor generator, where the first motor generator is power-coupled to the speed change unit; a speed change unit output portion, where the speed change unit output portion is constructed to be suitable for outputting power output through the speed change unit; a system power output portion; a mode conversion device, where the speed change unit output portion is power-coupled to or power-decoupled from the system power output portion through the mode conversion device, and the speed change unit output portion is power-coupled to the system power output portion through the mode conversion device, so that the mode conversion device is suitable for decelerating the power received from the speed change unit output portion and then outputting the decelerated power to the system power output portion; and a power switching device, where the speed change unit is power-coupled to or power-decoupled from the speed change unit output portion through the power switching device.
