Zusammenfassung: | To provide a hybrid vehicle control device capable of appropriately suppressing occurrence of vibrations and resonances during traveling on a rough road or a corrugated road so as to improve traveling performance and power performance.SOLUTION: A hybrid vehicle control device comprises: a driving power source which has an engine, a first motor, and a second motor; and a power transmission unit which is constituted of a first planetary gear mechanism and a second planetary gear mechanism, transmits torque through a drive system between the engine and the first motor and driving wheels, and has a first clutch and a second clutch for switching a transmission state of the torque. When excess input is applied to the drive system, the hybrid vehicle control device sets a disconnection mode of disconnecting the engine and the first motor from the drive system, and executes engine rotational speed control of causing the engine to operate so as to maintain an engine rotational speed higher than an idling rotational speed (step S5).SELECTED DRAWING: Figure 9
【課題】悪路や波状路を走行する際の振動や共振の発生を適切に抑制し、走破性能および動力性能を向上させることが可能なハイブリッド車両の制御装置を提供する。【解決手段】エンジン、第1モータ、および、第2モータを有する駆動力源と、第1遊星歯車機構および第2遊星歯車機構によって構成され、前記エンジンおよび前記第1モータと駆動輪との間の駆動系統でトルクを伝達するとともに、前記トルクの伝達状態を切り替える第1クラッチおよび第2クラッチを有する動力伝達部と、を備えたハイブリッド車両の制御装置であって、前記駆動系統に過大入力があった場合に、前記駆動系統から前記エンジンおよび前記第1モータを切り離す切り離しモードを設定するとともに、前記エンジンを運転し、前記エンジンの回転数をアイドリング回転数よりも高い状態に維持するエンジン回転数制御を実行する(ステップS5)。【選択図】図9 |
