Title:
DRIVE CONTROL DEVICE FOR HYBRID VEHICLE
Document Type and Number:
WIPO Patent Application WO/2013/088578
Kind Code:
A1
Abstract:
Provided is a drive control device for a hybrid vehicle wherein the generation of noise and vibrations are inhibited when reducing the engine speed. A drive control device for a hybrid vehicle, the drive control device being provided with a clutch (CL) for engaging/disengaging a carrier (C1) for a first planetary gear device (14) with/from a carrier (C2) for a second planetary gear device (16), and a brake (BK) for engaging/disengaging carrier (C2) with/from a housing (26), wherein the torque capacity of the clutch (CL) and/or the brake (BK) is increased when reducing the speed (NE) of an engine (12). As a consequence, it is possible to inhibit the generation of noise and vibrations by expediting the passage through a resonance frequency when reducing the engine speed (NE) as a result of increasing the toque capacity of the clutch (CL) and/or brake (BK).
