To prevent a line pressure from being lacked in a case where a driver has a tendency to perform a fluttering operation.SOLUTION: In a line pressure control device for a belt-type non-step 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 an own vehicle is accelerated/decelerated, learns for each of the divided traveling scenes whether a driver driving tendency is a fluttering operation type or a non-fluttering operation 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 the corresponding division and, in a case where the learning result of the driver driving tendency indicates the non-fluttering operation type, implements the line pressure reduction control but, in a case where the learning result indicates the fluttering operation type, does not implement the line pressure reduction control.SELECTED DRAWING: Figure 1
【課題】ドライバーがバタつき操作派の場合にライン圧不足が発生してしまうことを抑制すること。【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、自車に加減速が発生したとき、区分した走行シーン毎にドライバー運転嗜好がバタつき操作派であるのかバタつかない操作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、バタつかない操作派である場合はライン圧低下制御を実施し、バタつき操作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
