Torque control system and method for drive systems of electric vehicles

A torque control system for a drive system of an electric vehicle, the torque control system comprising:

• a driving information detector configured to detect information configured to indicate a vehicle driving state;
• a controller configured to generate a rear wheel torque command and a front wheel torque command configured to satisfy requested torque based on vehicle driving information including the information detected by the driving information detector;
• and
• a rear wheel motor and a front wheel motor controlled depending on the rear wheel torque command and the front wheel torque command generated by the controller,
• wherein the controller is configured to
• determine whether or not there is a virtual shift request depending on the vehicle driving state while executing a drift mode in which an electric vehicle is driven in a drift state by generating torque required to drive the electric vehicle only by the rear wheel motor and inducing rear wheel slip,
• determine rear wheel torque as a value changed, during gear shifting, from a target torque before the gear shifting to a target torque after the gear shifting, upon determining that there is the virtual shift request,
• determine front wheel torque as a shift intervention torque value configured to create a virtual shift feeling, and
• generate the rear wheel torque command and the front wheel torque command, as respecting command values, using the determined rear wheel torque and front wheel torque.
