Abstract
Proposed is a method of controlling motor driving of a hybrid electric vehicle. Sum torque of a first motor, which is directly connected to an engine, and a second motor, which is directly connected to an input end of a transmission, are determined based on request torque and torque distributed to the engine. One of a first synthetic efficiency map and a second synthetic efficiency map, to which different conversion references of the motor drive mode are set, are selectively applied to an efficiency map of the second motor, based on information about the motor drive mode applied to the second motor. The sum torque is distributed to each of the first motor and the second motor based on an efficiency map of the first motor and the efficiency map of the second motor.
