The invention discloses a multi-gear dual-motor hybrid electric vehicle and a transmission system thereof, the transmission system comprises a planetary gear structure, a first variable speed transmission structure, a second variable speed transmission structure and a final power output mechanism, the input end of the planetary gear structure is selectively in transmission connection or disconnection with an engine and a second motor; the first variable transmission structure comprises a first-gear transmission structure and a second-gear transmission structure which are independent from each other, and the output end of the planetary gear structure is selectively in transmission connection or disconnection with the first-gear transmission structure and the second-gear transmission structure; the input end of the second variable-speed transmission structure is connected with the first motor, and the output end of the second variable-speed transmission structure is in transmission connection with one of the second-gear transmission structure and the first-gear transmission structure; and the input end of the final power output mechanism is in transmission connection with the first-gear transmission structure and the second-gear transmission structure at the same time. By means of the transmission system, the problems that when a full dead axle gear structure runs and shifts gears, a pause feeling exists, and a two-gear ECVT power dividing mode is difficult to achieve are solved.
