PROBLEM TO BE SOLVED: To suppress deviation from a lane.SOLUTION: A lane deviation suppression apparatus (17), for use in suppressing deviation from a travel lane of a vehicle (1) that includes plural brake mechanisms (122FL, 122RL, 122FR, 122RR) that are disposed respectively to plural wheels for providing each of the plural wheels with brake force in accordance with hydraulic pressure, also includes hydraulic pressure control means (174) for controlling hydraulic pressure supplied to each of the brake mechanisms respectively disposed to the front and rear wheels so as to apply yaw moment in a direction to prevent deviation to the vehicle, by brake force respectively applied to the front and rear wheel on one side of the left and right of the plural wheels in a case where there is possibility of deviation. The hydraulic pressure control means controls hydraulic pressure so that an increase speed of hydraulic pressure supplied to a brake mechanism disposed in a rear wheel is slower than an increase speed of hydraulic pressure supplied to a brake mechanism disposed in a front wheel for a given period of time after starting to supply the hydraulic pressure.SELECTED DRAWING: Figure 7
【課題】車線逸脱を抑制する。【解決手段】車線逸脱抑制装置(17)は、複数の車輪各々に設けられ、該複数の車輪各々に油圧に応じた制動力を付与する複数の制動機構(122FL、122RL、122FR、122RR)を備える車両(1)において、該車両の走行車線からの逸脱を抑制する。当該車線逸脱抑制装置は、逸脱の可能性がある場合に、複数の車輪のうち左右一方の側の前輪及び後輪に夫々付与される制動力により、逸脱を回避する方向のヨーモーメントが車両に付与されるように、前輪及び後輪に夫々設けられた制動機構各々に供給される油圧を制御する油圧制御手段(174)を備える。該油圧制御手段は、油圧の供給開始時から所定時間、後輪に設けられた制動機構に供給される油圧の昇圧速度が、前輪に設けられた制動機構に供給される油圧の昇圧速度より遅くなるように油圧を制御する。【選択図】図7
