To prevent a re-acceleration request from being dissatisfied in a case where a driver has a tendency to pass a preceding vehicle.SOLUTION: In a line pressure control device for a belt-type non-stage transmission 3 comprising a vehicle control device 10 which implements line pressure reduction control, the vehicle control device 10 includes a driver driving tendency learning control part 11 and a line pressure switching control part 12. The driver driving tendency learning control part 11 divides a traveling scene of a vehicle into multiple scenes by combining judging items of a traveling environment and, when a preceding vehicle exists in front of an own vehicle, learns for each of divided traveling scenes whether a driver driving tendency is a preceding vehicle passing type and a preceding vehicle following type. The line pressure switching control part 12 detects a division of a traveling scene of the own vehicle during traveling, acquires a learning result of the driver driving tendency in a corresponding division and, in a case where the learning result of the driver driving tendency indicates the preceding vehicle following type, implements the line pressure reduction control but, in a case where the learning result indicates the preceding result passing type does not implement the line pressure reduction control.SELECTED DRAWING: Figure 1

    【課題】ドライバーが前車追い越し派の場合に再加速要求を満足できなくなることを防止すること。【解決手段】ライン圧低下制御を実施する車両制御装置10を備えるベルト式無段変速機3のライン圧制御装置において、車両制御装置10は、ドライバー運転嗜好学習制御部11と、ライン圧切り替え制御部12と、を有する。ドライバー運転嗜好学習制御部11は、車両の走行シーンを走行環境の判断項目の組み合わせにより複数に区分し、自車の前方に前車が存在するとき、区分した走行シーン毎にドライバー運転嗜好が前車追い越し派であるのか前車追従派であるのかを学習する。ライン圧切り替え制御部12は、走行中、自車の走行シーンの区分を検出し、該当する区分におけるドライバー運転嗜好の学習結果を取得し、ドライバー運転嗜好の学習結果が、前車追従派である場合はライン圧低下制御を実施し、前車追い越し派である場合はライン圧低下制御を実施しない。【選択図】図1
