| (54) | DRIVE CONTROL DEVICE FOR HYBRID VEHICLE |
| (57) Provided is a drive control device for a hybrid vehicle, the drive control device
being configured so that the reverse rotation of the engine is prevented when stopping
the rotational speed of the engine in order to switch from an engine travel mode to
an electric motor travel mode. When stopping the rotational speed (NE) of an engine
(12) in order to switch from an engine travel mode, in which the vehicle travels by
being driven by the engine (12), to an electric motor travel mode, an engine rotation
reduction control unit (80) employing an engagement element uses a clutch (CL) or
a brake (BK) to stop the rotational speed (NE) of the engine (12). When the rotational
speed (NE) of the engine reaches a target engine rotational speed (NE1) by the feedback
control of an engine rotation reduction control unit (78) employing an electric motor,
the engine rotation reduction control unit (80) employing the engagement element engages
the brake (BK) or the clutch (CL) to stop the rotational speed (NE) of the engine.
As a result, the rotational speed (NE) of the engine can be reduced without causing
the reverse rotation of the engine (12).
