A motor control system and a method thereof are provided for a vehicle having a plurality of motors as a driving power source. The system includes a request torque determination part that determines a request torque requested for the plurality of motors corresponding to a driver request torque. An optimal operating point torque determination part determines an optimal operating point torque for each of the plurality of motors according to a current rotation speed of each of the plurality of motors. An motor torque determination part then determines a target torque for each of the plurality of motors by distributing the request torque to the plurality of motors based on the optimal operating point torque.

Motor control system of vehicle and method thereof

A control method of a hybrid vehicle may include performing a series of commands by a control portion including determining whether an accelerator pedal change amount detected by an accelerator pedal sensor is greater than a predetermined value, starting up an engine through a Hybrid Shaft Generator (HSG) during conversion into an HEV mode from an EV mode, controlling the engine to output constant torque, and synchronizing engine torque with motor torque to engage a clutch.
