Abstract
A control apparatus for a power transmitting system of a vehicle includes a drive mode control portion for selectively establishing one of first and second engine-braking drive modes in which a braking torque of the engine is applied to the vehicle. The first engine-braking drive mode is established in an engaged state of the first coupling device, while the second engine-braking drive mode is established in an engaged state of the second coupling device. The drive mode control portion switches the power transmitting system between the first and second engine-braking drive modes, such that the engine speed is held constant in the process of switching between the first and second engine-braking drive modes.
