1. A vehicle comprising:
a motor coupled to a driveline;
a planetary gearset having each gear coupled to one of the driveline, an engine and a generator; and
a controller programmed to control the motor according to a difference between a driver torque demand and an estimated torque at the motor produced by the engine and generator based on an error between actual and estimated engine speed and an error between actual and estimated generator speed.
