Abstract
An upper limit charging rate is limited when a speed position of an automatic transmission is high as compared to when the speed position is low, so an engine is hard to enter a high torque state even when the speed position is high. Thus, it is possible to suppress vibrations and noise that tend to occur at the time when the engine is driven at a low rotation speed and high torque. On the other hand, the upper limit charging rate increases when the speed position is low as compared to when the speed position is high, with the result that a charging rate increases, so it is possible to keep a state of charge of a battery within an appropriate range.
