According to the present invention, a continuously variable automatic transmission system combined with a planetary gear set, wherein a transmission module is realized by combining a planetary gear mechanism and a fluid type power transmission mechanism, enables operation of the planetary gear mechanism and the fluid type power transmission mechanism to be automatically controlled by interworking with the number of rotation of a vehicle engine axis controlled by an accelerator which is operated by a vehicle driver even if a separate brake mechanism or a clutch mechanism to control operation of the planetary gear mechanism forming the transmission module is not installed. According to the present invention, a continuously variable automatic transmission system combined with a planetary gear set comprises: a transmission module arranged between a vehicle engine axis and an axle connected to a driving wheel; and an acceleration operation module controlling the number of rotation of the vehicle engine axis. The transmission module comprises: a planetary gear mechanism; and a fluid type power transmission mechanism. |
