CONTROL DEVICE OF VEHICLE DRIVE UNIT

To provide a control device of a vehicle drive unit which can suppress rattling sound in a continuously variable transmission without causing control interference when switching power transmission paths.SOLUTION: An electronic control device 100 of a vehicle drive unit 90 in which a first power transmission path PT1 via a gear mechanism 28 being a stepped transmission, and a second power transmission path PT2 via a belt-type continuously variable transmission 24 are selectively formed between an input shaft 22 and an output shaft 30, comprises: a first traveling state determination part 102 for determining whether or not the vehicle drive unit 90 is in a state that the first power transmission path PT1 is formed, and in a state that the vehicle drive unit is in a predetermined first traveling state having a possibility of occurrence of noise between the continuously variable transmission 24 and the input shaft 22; and a belt clamping force control part 106 for boosting belt clamping force Cp of the continuously variable transmission 24 higher than that in a second traveling state different from the first traveling state, when it is determined that the vehicle drive unit is in the first traveling state by the first traveling state determination part 102.SELECTED DRAWING: Figure 1 【課題】動力伝達経路の切り替えの際に制御干渉を発生させることなく、無段変速機でのガタ打ち音を抑制できる車両用駆動装置の制御装置を提供する。【解決手段】有段変速機であるギヤ機構２８を経由する第１の動力伝達経路ＰＴ１とベルト式無段変速機２４を経由する第２の動力伝達経路ＰＴ２とが入力軸２２と出力軸３０との間で選択的に形成される車両用駆動装置９０の電子制御装置１００は、車両用駆動装置９０が第１の動力伝達経路ＰＴ１が形成された状態であり且つ無段変速機２４と入力軸２２との間で異音が発生する可能性がある予め定められた第１の走行状態にあるか否かを判定する第１の走行状態判定部１０２と、第１の走行状態にあると第１の走行状態判定部１０２により判定された場合には、第1の走行状態とは異なる第２の走行状態のときよりも無段変速機２４のベルト挟圧力Ｃｐを高める制御を行うベルト挟圧力制御部１０６と、を備える。【選択図】図１
