Abstract

Systems and methods for operating a hybrid powertrain that includes an engine and a motor/generator are described. The systems and methods adjust battery charging and discharging as well as engine and motor torque based on whether or not the vehicle is operating in a cruise control mode. In one example, curves that provide a basis for operating an engine and motor based on driver demand torque are compressed during a vehicle cruise control mode to improve powertrain efficiency.
