Abstract

A hybrid controller for controlling a hybrid vehicle is set forth. The hybrid vehicle has an engine, an electric motor and an engine controller determining a crankshaft torque. The hybrid controller includes an optimization module determining an electric motor torque, determining an engine torque and communicating the engine torque from the hybrid controller to the engine controller. The hybrid controller also includes a motor control module controlling the electric motor based on the electric motor torque.
