Abstract
An electric motor control system for a vehicle includes a vehicle speed module that determines a vehicle speed. A closed loop (CL) module determines a CL torque based on a difference between a target vehicle speed and the vehicle speed. A motor torque module determines a motor torque based on the CL torque and a motor torque request determined based on a position of an accelerator pedal. A switching control module controls switching of an inverter based on the motor torque to control application of power to an electric motor of the vehicle.
