PROBLEM TO BE SOLVED: To provide a motorcar whose maximum permissible output of a motor is switched between modes, in which traveling performance is exerted in respective modes.SOLUTION: During EV traveling under first CD mode, a positive value Di1 is allocated to distribution ratio Di (S120), and during EV traveling under second CD mode (a mode where travelling performance is restricted when compared with the first CD mode), value 0 is allocated to the distribution ratio Di (S130). In addition, first, second pressurizing converter is controlled in a manner where a smaller reactor electric current from the second pressurizing converter (discharged electric power from a second battery) is applied in a case where the distribution ratio Di is small when compared with a case where the distribution ratio Di is large.SELECTED DRAWING: Figure 3 【課題】モータの最大許容出力をモードによって切り替えるものにおいて、モードに応じた走行性能を発揮できるようにする。【解決手段】第１ＣＤモードにおけるＥＶ走行のときには、分配率Ｄｉに正の値Ｄｉ１を設定し（Ｓ１２０）、第２ＣＤモード（第１ＣＤモードに比して走行性能を制限するモード）におけるＥＶ走行のときには、分配率Ｄｉに値０を設定する（Ｓ１３０）。そして、分配率Ｄｉが小さいときには大きいときに比して第２昇圧コンバータのリアクトルの電流（第２バッテリからの放電電力）が小さくなるように第１，第２昇圧コンバータを制御する。【選択図】図３
