Abstract
Systems and methods for starting an engine are described. In one example, engine cranking speed for an engine of a hybrid vehicle is adjusted in response to operating conditions. The engine cranking speed may be reduced when capability of a battery that supplies power to rotate the engine is less than an amount of power to rotate the engine at a higher speed.
