The invention discloses a forward collision early warning moment dynamic adjustment method. The method comprises the following steps: acquiring a whole vehicle signal; obtaining target information acted by the FCW through environment perception, wherein the target information comprises motion information, position information and shape; judging which one of preset self-vehicle driving scenes the current self-vehicle driving scene belongs to according to the whole vehicle signal and the target information; and calculating an adjustment value of the triggering FCW collision time threshold according to the current self-vehicle driving scene, and adjusting the triggering FCW collision time threshold according to the adjustment value. According to the real-time whole vehicle signal, the driving state of the driver and the driving scene obtained by the environment perception sensor, the FCW triggering opportunity is dynamically adjusted, the sensitive degree of the FCW triggering condition is automatically changed, and the FCW alarming opportunity is more reasonable.

    本发明公开了一种前向碰撞预警时刻动态调整方法,包括:获取自车整车信号;通过环境感知获取FCW所作用目标信息,所述目标信息包括:运动信息、位置信息和形状;根据自车整车信号和目标信息判断当前自车驾驶场景属于预设自车驾驶场景的中哪一种;根据当前自车驾驶场景计算触发FCW碰撞时间阈值的调整值,根据调整值调整触发FCW碰撞时间阈值。本发明根据实时整车信号、驾驶员驾驶状态和环境感知传感器获取的驾驶场景,动态地调整FCW触发的时机,自动改变FCW触发条件的敏感程度,使得FCW报警的时机更加合理。
