To curb deterioration of controllability of automatic parking control when executing the same.SOLUTION: While automatic parking control AP is in execution, calculation accuracy of estimated drive force Fdest can be improved by calculating estimated drive force Fdest, taking into consideration inertia torque loss Tloss and transmission efficiency ηpt. In addition, because the automatic parking control AP is executed with a travel mode set to a gear travel mode or a belt travel mode combined with fixing a transmission gear ratio γcvt of a continuously variable transmission mechanism 24 to a least transmission gear ratio γmax, an unstable factor due to continuous transmission gear shift can be eliminated when calculating the estimated drive force Fdest to be used in the automatic parking control AP taking into consideration the inertia torque loss Tloss and the transmission efficiency ηpt. Thus, deterioration of controllability of the automatic parking control AP can be curbed when executing the same.SELECTED DRAWING: Figure 3

    【課題】自動駐車制御を実行する際に、自動駐車制御の制御性の低下を抑制する。【解決手段】自動駐車制御APの実行中には、慣性損失トルクTloss及び伝達効率ηptが加味されて、推定駆動力Fdestが算出されるので、推定駆動力Fdestの算出精度が向上させられる。加えて、自動駐車制御APには、走行モードがギヤ走行モードとされるか、又は、走行モードがベルト走行モードとされ且つ無段変速機構24の変速比γcvtが最ロー側変速比γmaxに固定されるので、自動駐車制御APに用いられる推定駆動力Fdestの演算において慣性損失トルクTloss及び伝達効率ηptが加味される場合に、連続的な変速に伴う不安定要素が払拭される。よって、自動駐車制御APを実行する際に、自動駐車制御APの制御性の低下を抑制することができる。【選択図】図3
