To provide a vehicular power transmission device configured to favorably suppress abnormal sound generated from a switching sleeve, during switching operation of a high-low switching mechanism during stopping of a vehicle.SOLUTION: An electronic control device 60 controls a rotation speed Nmg of an electric motor MG so that the rotation speed of an input shaft 36 becomes zero, during switching operation of a high-low switching mechanism 40 during stopping of a vehicle. Therefore, the rotation speed Nmg of the electric motor MG is controlled by the electronic control device 60 so that the rotation speed of the input shaft 36 becomes zero, during the switching operation of the high-low switching mechanism 40 during the stopping of the vehicle, which prevents the rotation speed of the input shaft 36, or the rotation speed of a sun gear S and a carrier CA, from increasing during the switching operation of the high-low switching mechanism 40. This can favorably suppress abnormal sound generated from a high-low switching sleeve 64 accompanying the increase in the rotation speed of the input shaft 36 during the switching operation of the high-low mechanism 40 during the stopping of the vehicle.SELECTED DRAWING: Figure 8
【課題】車両停車中においてハイロー切替機構の切替動作中に切替スリーブから発生する異音を好適に抑制する車両用動力伝達装置を提供する。【解決手段】電子制御装置60は、車両停車中においてハイロー切替機構40の切替動作中に入力軸36の回転速度がゼロになるように電動モータMGの回転速度Nmgを制御する。このため、車両停止中においてハイロー切替機構40の切替動作中に電子制御装置60によって入力軸36の回転速度がゼロになるように電動モータMGの回転速度Nmgが制御され、ハイロー切替機構40の切替動作中に入力軸36の回転速度すなわちサンギヤSおよびキャリアCAの回転速度が上昇することが抑制されるので、車両停車中においてハイロー切替機構40の切替動作中に入力軸36の回転速度が上昇することに伴うハイロー切替スリーブ64から発生する異音が好適に抑制される。【選択図】図8
