Patent ID: 8002059

Claim:
A controlling device for a hybrid vehicle, comprising: an engine; a motor-generator; a first clutch whose torque transfer capacity is changeable between the engine and the motor-generator; a second clutch whose torque transfer capacity is changeable between the motor-generator and a driving wheel; and a controller configured to: control a selection between an electric drive mode, in which the hybrid vehicle travels by using the motor-generator while the first clutch is disengaged and the second clutch is engaged, and a hybrid drive mode, in which the hybrid vehicle travels by at least driving force of the engine while the first clutch and the second clutch are engaged; perform mode switching from the hybrid drive mode to the electric drive mode by reducing the torque transfer capacity of the second clutch, then initiating a stop of the engine, and then disengaging the first clutch; and disengage the first clutch after an engine torque set during operation of the engine reaches substantially zero as a result of completing the stop of the engine, based on an elapsed time measured from a moment when a mode switching command for switching from the hybrid drive mode to the electric drive mode is issued.
