A torque distribution method for an engine and a motor of an energy-efficient hybrid electric vehicle comprises the following steps: providing an offline specific fuel consumption map of the engine in all operating states; enabling the engine and motor to respond to the required torque T during travelling together, the motor and the engine working in cooperation at the same rotational speed so as to achieve the optimal working efficiency; acquiring a current state of charge (SOC) of the vehicle battery, and distributing the engine torque T and the motor torque T according to the following situation: if the SOC is greater than a first preset value, entering a first distribution mode; if the SOC is less than a second preset value, enter a second distribution mode; and otherwise, maintaining the current working state. The method can fully utilize the performance advantage of the engine and that of the motor, so that the system works at high efficiency all the time, thereby decreasing the energy consumption of the vehicle, greatly reducing harmful emission, and facilitating energy conservation and environmental protection.
