To suppress inconvenience such as vibration that may occur during high-speed traveling.SOLUTION: A hybrid vehicle includes: an engine in which an exhaust system is attached with a purification device having a catalyst that purifies exhaust gas; a first motor; a planetary gear mechanism in which a rotation shaft of the first motor, an output shaft of the engine, and a drive shaft coupled to a drive wheel are connected to three shafts arranged in order in an alignment chart in this order; and a second motor in which a rotation shaft is coupled to the drive shaft. A control device of the hybrid vehicle performs catalyst warming-up control of warming the catalyst of the purification device by setting a rotation speed of the engine to a predetermined engine rotation speed and retarding an ignition timing of the engine. When a vehicle speed is equal to or higher than a predetermined vehicle speed, the control device prohibits the catalyst warming-up control.SELECTED DRAWING: Figure 4
【課題】高車速で走行しているときに生じ得る振動などの不都合を抑制する。【解決手段】ハイブリッド車は、排気を浄化する触媒を有する浄化装置が排気系に取り付けられたエンジンと、第1電動機と、共線図上に順に並ぶ3軸にこの順に第1電動機の回転軸とエンジンの出力軸と駆動輪に連結された駆動軸とが接続された遊星歯車機構と、駆動軸に回転軸が連結された第2電動機と、を備える。ハイブリッド車の制御装置は、エンジンの回転数を所定エンジン回転数とすると共にエンジンの点火時期を遅角して浄化装置の触媒を暖機する触媒暖機制御を実行する。また、制御装置は車速が所定車速以上のときには触媒暖機制御を禁止する。【選択図】図4
