Abstract:
In a hybrid vehicle including an engine, a first motor, a differential unit, a second motor, a driving force split device, and a controller, the controller is configured to control the engine, the first motor, and the second motor such that the hybrid vehicle travels with the engine rotating within a range of an allowable maximum rotational speed for control or less. In this case, the controller is configured to set the allowable maximum rotational speed such that the allowable maximum rotational speed is higher when a main-side ratio is lower than when the main-side ratio is higher. The main-side ratio is a ratio of a driving force that is transmitted to main drive wheels to the total driving force that is transmitted from a drive shaft to the main drive wheels and sub drive wheels via the driving force split device.
