METHOD FOR CONTROLLING TORQUE OF ENGINE AND CONTROL APPARATUS

A method for controlling a torque of an engine, comprising: on the basis of a relationship between a required torque of an engine of a hybrid vehicle (HEV) and a preset parameter, determining a working range of the engine, the preset parameter comprising a torque for an optimum efficiency of the engine and a maximum torque of the engine; determining a working mode of a motor on the basis of the working range of the engine; and on the basis of the working mode of the motor, controlling a torque of the motor, such that the engine works by using the torque for the optimum efficiency. The described method enables an adjustment range for a working point of an engine of a HEV to be wider, while control is more precise, and the suitable range is wide; and moreover, the described method can be applied to control of HEVs having various structures. Also provided is a torque control apparatus.
