Abstract

A torque control system comprises a torque correction factor module, a RPM-torque transition module, and a selection module. The torque correction factor module determines a first torque correction factor and a second torque correction factor. The RPM-torque transition module stores the first torque correction factor. The selection module selectively outputs one of the first torque correction factor and the second torque correction factor based on a control mode of the torque control system.
