PROBLEM TO BE SOLVED: To provide a driving support device and a driving support method that can more accurately perform determination of whether or not a vehicle is travelling toward a support intersection.SOLUTION: In a case that an entering direction D1 of a vehicle 41 toward an upstream intersection P6 of a support target section 43f is different from a straight line direction D2 of the support target section 43f, when a difference between the straight line distance and a route distance of the support target section 43f is more than or equal to a predetermined threshold value, if an angular difference between the entering direction D1 of the vehicle 41 toward the upstream intersection P6 and an escape direction D3 of the vehicle 41 from the upstream intersection P6 is less than the predetermined threshold value, it can be performed to determine whether or not the vehicle 41 has entered the support target section 43f without depending on such a road shape, by determining that the vehicle 41 has entered the support target section 43f, even when the road of the support target section 43f curves largely, or bends on the way.SELECTED DRAWING: Figure 6 【課題】支援交差点に向かって車両が走行しているか否かの判定をより高精度に行うことが可能な「運転支援装置および運転支援方法」を提供する。【解決手段】支援対象区間４３ｆの上流交差点Ｐ６への車両４１の進入方向Ｄ１と、支援対象区間４３ｆの直線の方向Ｄ２とが異なる場合において、支援対象区間４３ｆの直線距離と道程距離との差が所定の閾値以上である場合、上流交差点Ｐ６への車両４１の進入方向Ｄ１と、上流交差点Ｐ６からの車両４１の脱出方向Ｄ３との角度差が所定の閾値未満であったとき、支援対象区間４３ｆに車両４１が進入したと判定することにより、支援対象区間４３ｆの道路が大きくカーブしていたり、途中で折れ曲がったりしている場合であっても、このような道路形状に依らずに、車両４１が支援対象区間４３ｆに進入したか否かの判定を行うことができるようにする。【選択図】図６
