Abstract
A hybrid vehicle drive control system is configured to perform engine startup when switching from an electric drive mode to a hybrid drive mode, without creating a sense of output torque loss. In particular, a controller selectively controls a first clutch disposed between the engine and the motor/generator and a second clutch disposed between the motor/generator and a drive wheel to switch between an electric drive mode in which the first clutch is released and the second clutch is engaged, and a hybrid drive mode in which both the first and second clutches are engaged. The controller sets the second torque transfer capacity to a value that is more than zero and less than the target motor/generator torque of the motor/generator when switching from the electric drive mode to the hybrid drive mode and when starting the engine.
