The invention discloses a double-mode hybrid vehicle and a five-parameter control method and device of a working mode of the vehicle. The method comprises the steps of obtaining the current vehicle speed of double-mode hybrid vehicle; according to the engine idle rotating speed, the tire size and the final ratio of the double-mode hybrid vehicle, obtaining the idle vehicle speed corresponding to the idle rotating speed; if the current vehicle speed is smaller than or equal to the idle vehicle speed, obtaining a first working mode distribution model; if the current vehicle speed is larger than the idle vehicle speed, obtaining a second working mode distribution model; obtaining current battery charge state and wheel required torque of a power battery of the double-mode hybrid vehicle; according to the current battery charge state, the wheel required torque and the first working mode distribution model or the second working mode distribution model, determining the working mode of the double-mode hybrid vehicle. The frequent jumping problem between the working modes is solved, the comprehensive performance of the double-mode hybrid vehicle is improved, the fuel economy is improved, and the user experience is improved.
