PROBLEM TO BE SOLVED: To suppress the occurrence of a clattering noise and improve the fuel economy of a vehicle.SOLUTION: A vehicular control apparatus 100, for use in controlling a gear ratio of a stepless transmission 40 and a revolution speed of an engine 2, includes: a determination part 100a for determining a load state of an auxiliary machine 120 provided in a vehicle 1; a first control part 100b for controlling the gear ratio of the stepless transmission 40 and the revolution speed of the engine 2 so as to maintain the revolution speed of the engine 2 at a first revolution speed during engagement of a lockup clutch 25, in the case of the load state being less than a given value; and a second control part 100c for controlling the gear ratio of the stepless transmission 40 and the revolution speed of the engine 2 so as to set the revolution speed of the engine 2 at a second revolution speed being higher than the first revolution speed during engagement of the lockup clutch 25 so that an operation state of the engine 2 falls out of a range of load under a low revolution speed, in the case of the load state being equal to or more than the given value.SELECTED DRAWING: Figure 3 【課題】ガタ打ち音の発生を抑制するとともに、車両の燃費を向上させる。【解決手段】車両の制御装置１００は、無段変速機４０の変速比およびエンジン２の回転数を制御するように構成された制御装置１００であって、車両１に備えられた補機１２０の負荷状態を判定する判定部１００ａと、負荷状態が所定値未満である場合に、ロックアップクラッチ２５の係合中におけるエンジン２の回転数を、第１の回転数に維持するように無段変速機４０の変速比およびエンジン２の回転数を制御するように構成された第１制御部１００ｂと、負荷状態が所定値以上である場合に、エンジン２の運転状態を低回転中負荷の領域から外れるように、ロックアップクラッチ２５の係合中におけるエンジン２の回転数を第１の回転数よりも高い第２の回転数にするように無段変速機４０の変速比およびエンジン２の回転数を制御するように構成された第２制御部１００ｃと、を備えている。【選択図】図３
