Abstract

A method of controlling electric motor torque in an electric vehicle for improved vehicle performance and energy conservation includes receiving a throttle torque request and a brake torque request, and sensing the speed of the vehicle. The brake torque request is split into a creep cancellation component and a brake regenerative component. The throttle torque request is adjusted based upon the creep cancellation component and the brake regenerative component to produce a torque sum. The electric motor torque is then controlled based upon the torque sum.
