TORQUE CONTROL SYSTEM AND METHOD FOR DRIVE SYSTEM OF ELECTRIC VEHICLE

A torque control system of an electric vehicle includes a controller that generates front-wheel and rear-wheel torque commands having torque values distributed from a required torque for vehicle driving, and front-wheel and rear-wheel motors whose operations are controlled according to the front-wheel and rear-wheel torque commands. The controller determines whether there is a change request of a direction of the required torque, determines, in response that there is the change request of the direction of the required torque, the front-wheel and the rear-wheel torque commands determined from the required torque as values for sequential zero-crossing while the required torque determined in real time changes while performing zero-crossing, and determines a time point at which the front-wheel torque command performs zero-crossing and a time point at which the rear-wheel torque command performs zero-crossing based on the required torque determined in real time.
