To improve traveling performance in a vehicle driving environment where all wheels are in a slip state.SOLUTION: A vehicle control system according to the present invention is a vehicle control system in a vehicle that has a plurality of wheels and that can switch between an all-wheel drive state in which all wheels are driven and a partial wheel drive state in which only some wheels are driven. The vehicle control system comprises: a wheel rotation speed detection unit that detects wheel rotation speed for each wheel; and a control unit that switches from the all-wheel drive state to the partial wheel drive state when it is determined that all the wheels are in a slip state.SELECTED DRAWING: Figure 3 【課題】全車輪がスリップ状態となる車両走行環境下における走破性の向上を図る。【解決手段】本発明に係る車両制御システムは、複数の車輪を有し、全ての車輪を駆動する状態である全輪駆動状態と、一部の車輪のみを駆動する状態である一部車輪駆動状態との切り替えが可能とされた車両における車両制御システムであって、車輪ごとに車輪回転速を検出する車輪回転速検出部と、全輪駆動状態において、全ての車輪がスリップ状態であると判定した場合に、全輪駆動状態から一部車輪駆動状態に切り替える制御を行う制御部とを備える。【選択図】図３
