Claim 0:
1. A control device for a vehicle, the vehicle including an engine, a first electric motor that is connected to the engine in a power-transmittable manner, an automatic transmission that constitutes a part of a power transmission path which is formed such that power of the engine and power of the first electric motor are able to be transmitted to driving wheels, and a second electric motor that is configured to transmit power of the second electric motor to the driving wheels without passing through the automatic transmission, the control device comprising:
a limp-home travel control unit configured to, when an abnormality associated with power transmission in the power transmission path has occurred, alternatively switch a limp-home travel mode in which predetermined limp-home travel is able to be performed between:
a first limp-home travel mode in which limp-home travel is performed in a state in which a fail-safe power transmission path in which the power of the engine and the power of the first electric motor are able to be transmitted to the driving wheels is formed in the power transmission path when a vehicle speed is equal to or higher than a predetermined vehicle speed; and
a second limp-home travel mode in which the power transmission path is switched to a power-untransmittable state in which the power of the engine and the power of the first electric motor are not able to be transmitted to the driving wheels and limp-home travel is performed using power of the second electric motor when the vehicle speed is lower than the predetermined vehicle speed.
