To achieve improvement in a degree-of-freedom of a vehicle undercarriage design while obtaining a stable brake force during traveling downhill.SOLUTION: This power transmission control apparatus is a power transmission control apparatus in a vehicle having at least two wheel groups, in a cross direction, each of which has two wheels comprising a pair of wheels located on the left and right sides. The power transmission control apparatus comprises: an intermittent part where power transmission from a driving source owned by the vehicle can be freely interrupted to each wheel of an object wheel group which is such a wheel group that the wheel groups are subtracted by at least one wheel group; an intermittent changeover part which performs changeover of power transmission intermittence by the intermittent part on the basis of a brake pressure for operating a brake mechanism of a wheel; a downhill estimation part which estimates whether the vehicle is in such a state that the vehicle travels downhill or not; and a control part which controls the intermittent changeover part so that the intermittent part is changed into such a state as to perform power transmission when it is estimated on the basis of the estimated result of the downhill estimation part that the vehicle is in such a state that the vehicle travels downhill.SELECTED DRAWING: Figure 5

    【課題】降坂中に安定した制動力が得られるようにしつつ、車両の足回り設計の自由度向上を図る。【解決手段】本発明に係る動力伝達制御装置は、左右一対に配置された二つの車輪を有する車輪組を前後方向に少なくとも二つ有する車両における動力伝達制御装置であって、車輪組のうち少なくとも一つの車輪組を除いた車輪組である対象車輪組について、車両が有する駆動源から該対象車輪組の各車輪への動力伝達を断続自在とされた断続部と、車輪のブレーキ機構を作動させるブレーキ圧に基づいて、断続部による動力伝達の断続を切り替える断続切替部と、車両が降坂状態であるか否かを推定する降坂推定部と、降坂推定部の推定結果に基づき、車両が降坂状態であると推定された場合に、断続部が動力伝達を行う状態に切り替わるように断続切替部を制御する制御部とを備えている。【選択図】図5
