To effectively reduce an input-output rotation speed difference of a synchronizer at the time of down-shift in which the synchronizer is exerted with a load equaling or exceeding a given magnitude.SOLUTION: A control apparatus includes: a determination part 110 for determining whether a load equaling or exceeding a given magnitude is exerted to a synchronizer 70 in a case where a transmission 60 is down-shifted from a present gear stage; and a control part 120 for switching a clutch device 20 from a disconnect state where no power is transmitted to a connect state where the power is transmitted and increasing an output rotation speed of a drive power source 10 during the time when the transmission 60 is in a neutral state before completing the downshift, in a case where the determination part 110 determines that a load equaling or exceeding the given magnitude is exerted at the downshift of the transmission 60, thus executing rotation speed difference reduction control for reducing the input-output rotation speed difference of the synchronizer 70.SELECTED DRAWING: Figure 3
【課題】同期装置に所定以上の負荷が付与されるシフトダウン時に、同期装置の入出力回転数差を効果的に低減する。【解決手段】変速機60が現在のギヤ段からシフトダウンされた場合に、同期装置70に所定以上の負荷が付与されるか否かを判定する判定部110と、変速機60のシフトダウン時に、判定部110により所定以上の負荷が付与されると判定されると、変速機60がシフトダウンを完了するよりも前のニュートラル状態の時に、クラッチ装置20を動力の伝達を遮断する断状態から動力を伝達する接状態に切り替えると共に、駆動力源10の出力回転数を上昇させることにより、同期装置70の入出力回転数差を低減させる回転数差低減制御を実施する制御部120とを備えた。【選択図】図3
