PROBLEM TO BE SOLVED: To execute lane keeping control as continuously as possible even in a condition where a lane width gradually increases.SOLUTION: Lane keeping control is performed so as not to deviate from a lane width H1 by detecting the lane width H1 of a travelling lane 21 by a camera 4. When the gradual widening of the travelling lane 21 is detected by the camera 4 (H2>H1, H2 representing a lane width), the lane keeping control continues on the condition that a winker is not operated. The continued lane keeping control can be performed by assuming, for example, a travelling scheduled lane width by the lane width H1 immediately before the gradual increase of the lane width and a center boundary line 23.SELECTED DRAWING: Figure 3

    【課題】車線幅が徐々に増大しているような状況でも、車線維持制御を極力継続して行えるようにする。【解決手段】カメラ4によって走行車線21の車線幅H1を検出して、車線幅H1から逸脱しないように車線維持制御が行われる。カメラ4によって走行車線21が徐々に拡大していること(車線幅H2で、H2>H1)が検出されたときは、ウインカが操作されていないことを条件として、車線維持制御が継続して続行される。車線維持制御の継続した続行は、例えば、車線幅が徐々に拡大する直前の車線幅H1と中央境界線23とによって走行予定の車線幅を想定して行う等のことができる。【選択図】 図3
