TORQUE CONTROL SYSTEM AND METHOD FOR DRIVE SYSTEM OF ELECTRIC VEHICLE

A torque control system for a drive system of an electric vehicle includes a controller that generates a front-wheel torque command and a rear-wheel torque command having torque values distributed from required torque for vehicle driving, a front-wheel motor, wherein operation of the front-wheel motor is controlled according to the front-wheel torque command, and a rear-wheel motor, wherein operation of the rear-wheel motor is controlled according to the rear-wheel torque command. The controller determines whether there is a change request of a direction of the required torque, and determines, in a case where there is the change request of the direction of the required torque, the front-wheel torque command and the rear-wheel torque command determined from the required torque as values for sequential zero-crossing while the required torque determined in real time changes while performing zero-crossing of passing through 0 torque for direction change.
