1. A smart glass transmittance control system of a vehicle, the smart glass transmittance control system comprising:
a smart glass configured to decrease transmittance of the smart glass in response to a quantity of light introduced into the vehicle and increase the transmittance of the smart glass when electric power is supplied;
a power supply unit supplying the electric power to the smart glass; and
a control unit controlling supply of the electric power from the power supply unit to the smart glass to control the transmittance of the smart glass according to a user request,
wherein the control unit controls the supply of the electric power to the smart glass based on a driving environment of a vehicle, a quantity of light from an external light source, or a driving environment condition of the smart glass,
wherein the control unit enters a night mode when the quantity of light introduced is less than a first reference value and determines whether the quantity of light introduced is equal to or less than a third reference value,
wherein the control unit applies the electric power to the smart glass when the quantity of light introduced is equal to or less than the third reference value, and determines whether a quantity of light transmitted through the smart glass is equal to or greater than the third reference value, and
wherein the control unit turns power off when the quantity of light transmitted through the smart glass is equal to or greater than the third reference value.
