The invention discloses a multimode double-gear-ring meshing hybrid power driving system. An engine and a first motor jointly drive a first planet row mechanism; the first planet row mechanism drivesa second planet row mechanism; the second planet row mechanism is in transmission connection with a second motor and further drives a differential mechanism assembly, the structure of double planet row mechanisms with two parallel axes and direct connection is simple in structure and high in reliability, and when energy flow control of the controller is conducted, the engine can be ensured to workin the optimal oil consumption area as much as possible; when an engine and a motor are braked or separated by selecting different combined brakes, various driving modes including independent drivingof each power source, pairwise combined ECVT driving, combined ECVT driving of the three power sources and various extended ranges are realized, the mode switching mode is reliable, and the system isthe optimal design scheme of the power system for the hybrid electric vehicle.
