Abstract
Systems and methods for operating a vehicle that includes an engine and an integrated starter/generator are described. In one example, a torque output of an electric machine is increased via a rotation ratio changing device to reduce engine noise and vibration during engine starting. After the engine is started, the rotation ratio changing device is adjusted so that the engine and the electric machine rotate at a same speed.
