A control apparatus for a hybrid vehicle for controlling and limiting the transmission of power from an engine to the driving wheels during start-up of the engine to produce a hybrid running mode where the vehicle is powered by both the engine and a motor-generator. During start-up of the engine, a first frictional element changing its state before and after a shift of the transmission is allowed to slip, and a second frictional element is allowed to slip. The element that is allowed to slip is switched from one to the other.

What is claimed is: 1. An apparatus for controlling a hybrid vehicle having an engine, a motor-generator, and clutch disposed between the engine and the motor and configured to vary a transmitted torque capacity, comprising:a transmission disposed between the motor-generator and at least one driving wheel having at least two power transmitting paths through the selective engagement of a plurality of frictional engagement elements; anda controller configured to:perform a transition of the vehicle from an electric running mode wherein the clutch is disengaged to a hybrid running mode wherein the clutch is engaged and the engine is started, the transition responsive to a request for start up of the engine;determine a need for a shift of the transmission responsive to a request for driving force for the vehicle, at least a first frictional engagement element changing from being engaged before the shift to being disengaged after the shift or changing from being disengaged before the shift to being engaged after the shift;responsive an earlier of a determination of the need for the shift and the request for start up of the engine, permit a first slip state where one of the first frictional engagement element and a second frictional engagement element is allowed to slip while the other of the first frictional engagement element and the second frictional engagement element is not allowed to slip;during the transition, perform a switch to permit a second slip state where the other of the first frictional engagement element and the second frictional engagement element is allowed to slip and the one of the first frictional engagement element and the second frictional engagement element allowed to slip in the first slip state is not allowed to slip, each of the first slip state and the second slip state controlling the driving force transmitted to the at least one driving wheel; andcomplete the shift by preventing both the first frictional engagement element and the second frictional engagement element from slipping.
