Systems and methods for operating a hybrid vehicle having an internal combustion engine are presented. In one example, the internal combustion engine is operated in a speed control mode and torque of an electric machine is adjusted so that a possibility of an engine speed controller saturating may be reduced.

System and method for detecting and correcting engine speed controller saturation

Systems and methods for operating a hybrid vehicle during an end of assembly line test are presented. In one example, torque of an integrated starter/generator (ISG) is adjusted so that the ISG may not affect engine data that is collected during end of assembly line engine testing. The collected engine data may be a basis for adapting engine operation.

System and method for completing a neutral profile learning test

A hybrid vehicle includes an electric machine, an engine selectively coupled to the electric machine by a disconnect clutch, and a controller. The controller is programmed to, in response to a change in the driver-demanded torque necessitating starting of the engine: determine a state of driving (SOD) based on the change in driver-demanded torque, wherein the SOD is indicative of a desired responsiveness of the vehicle, and the desired responsiveness increases as SOD increases; command a speed target to the engine equal to a predicted motor speed associated with the driver-demanded torque plus an offset that is based on the SOD; and command a capacity to the disconnect clutch at a rate and a magnitude based on the SOD.
