The invention discloses a hybrid power system and a hybrid vehicle, relates to the technical field of vehicle control, and aims to improve the operation efficiency and reliability of the hybrid vehicle. The hybrid power system comprises an electronic oil pump; a mechanical oil pump connected to the engine and driven by the operation of the engine; the first end of the hydraulic module is connected with the electronic oil pump and the mechanical oil pump; the first cooling oil way corresponds to the driving motor and is connected with the second end of the hydraulic module; the second cooling oil way corresponds to the driving motor and the generator and is connected with the third end of the hydraulic module; when the vehicle is in a pure electric mode, the first cooling oil way is conducted and the second cooling oil way is closed through the hydraulic module, and the electronic oil pump is controlled to be in a working state, so that only the driving motor is cooled; and when the vehicle is in a hybrid mode, the second cooling oil way is conducted through the hydraulic module, and cooling of the driving motor and the generator is achieved based on the mechanical oil pump or the mechanical oil pump and the electronic oil pump.
