According to the present invention, there is provided a control device for a vehicle capable of preventing generation of mechanical noise from an exhaust pressure relief valve and electromagnetic noise generated from an actuator due to vibration when a vehicle having an internal combustion engine and an electric motor as a drive source is driven in a motor drive mode Happening. The engine (1) is automatically stopped while the motor (61) is driven in the motor drive mode in which the vehicle (61) is driven only as the drive source, and the target opening WGCMD of the exhaust pressure relief valve (14) is set to (14) in such a manner that the opening WGO of the exhaust pressure relief valve (14) detected by the valve opening sensor (23) coincides with the target opening WGCMD. The predetermined opening degree WGX is set so that the actual opening degree WGA does not become the same as the fully closed degree when the error between the detected WG opening WGO and the actual opening WGA becomes the assumed maxim
