Zusammenfassung:	To provide a travel control system and a travel control method that enable a vehicle to automatically travel in a stable vehicle behavior.SOLUTION: A travel control system 10 for a vehicle 1 includes: environment recognition means 31 that recognizes an obstacle around the vehicle; tire parameter estimation means 22 that estimates a tire parameter of a tire of the vehicle; and travel planning means 34 that sets a travel route, an acceleration amount, and a turning amount based on the obstacle and the tire parameter. The travel planning means sets the travel route, the acceleration amount, and the turning amount to avoid an approach to the obstacle and suppress an excess of a slip ratio of the tire to an adhesion limit slip ratio.SELECTED DRAWING: Figure 11 【課題】車両挙動が安定した状態で車両を自動走行させることができる車両制御システム及び車両制御方法を提供する。【解決手段】車両１の走行制御システム１０であって、車両の周囲の障害物を認識する外界認識手段３１と、車両のタイヤのタイヤパラメータを推定するタイヤパラメータ推定手段２２と、障害物とタイヤパラメータとに基づいて走行経路、加減速量、及び旋回量を設定する走行計画手段３４とを有し、走行計画手段は、障害物への接近を避けつつ、かつタイヤのスリップ率の粘着限界スリップ率に対する超過量を抑制するように、走行経路、加減速量、及び旋回量を設定する。【選択図】図１１
