The invention discloses a driving mode control system and method for an electromechanical coupling double-clutch hybrid power system. The driving mode control system comprises a mode arbitration module, a traditional mode demand module, a pure electric mode demand module, a power-assisted mode demand module, a charging mode demand module and an energy recovery mode demand module which are respectively connected with the mode arbitration module. The engine torque demand and the motor torque demand under each mode can be calculated in each mode; and an engine gear demand and a motor gear demandin the mode are calculated according to the torque demand and the current vehicle state, the efficiency in the mode is calculated according to the calculated engine and motor torque demand, gear demand and other signals, and the weight coefficient is calculated in the mode according to the efficiency. And finally, the mode arbitration module selects the engine torque demand, the motor torque demand, the engine gear demand and the motor gear demand of the optimal mode according to the weight coefficients of the modes and outputs the engine torque demand, the motor torque demand, the engine geardemand and the motor gear demand to an engine controller, a motor controller and a gearbox controller respectively.
