Systems and methods for starting an engine of a hybrid vehicle are described. In one example, the method starts an engine according to vehicle conditions that are within a range that is defined by one or more thresholds. The thresholds may be adjusted based on a history of individual driving patterns.

A system and method for controlling a hybrid vehicle having an engine, a traction motor, and an automatic step-ratio transmission having a plurality of selectable discrete gear ratios include operating the electric machine to provide output torque associated with a first operating point selected based on driver demand torque and a current powertrain speed during transient operation, operating the electric machine to provide an output torque associated with a second operating point selected based on the driver demand torque and the current powertrain speed during steady state operation, and controlling the engine torque based on a difference between the driver demand torque and the electric machine torque.
