The invention discloses an LDW repeated alarm suppression method. The method comprises the steps that deviation calculation models of vehicle straight going and vehicle turning are established respectively; according to the deviation calculation model and the vehicle driving parameters at the current moment, TLC and DLC are obtained through calculation, the TLC is the touch time of the center of a front wheel and a lane line, and the DLC is the touch distance of the center of the front wheel and the lane line; and according to the TLC and the DLC, whether line crossing occurs is determined and alarm suppression is outputted. On the premise of not increasing the hardware cost of the LDW, repeated alarming after the vehicle crosses the line is restrained, false alarming and missing alarming of the LDW can be reduced, and the driving experience can be improved.
本发明公开了一种LDW重复报警抑制方法,包括:分别搭建车辆直行和车辆转弯的偏移计算模型;根据上述偏移计算模型和当前时刻车辆行驶参数,计算获得TLC和DLC,所述TLC为前轮中心与车道线的触碰时间,所述DLC为前轮中心与车道线的触碰距离;根据TLC和DLC判断是否越线及输出报警抑制。本发明在不增加LDW硬件成本前提下抑制车辆越线后重复报警,且能降低LDW的误报和漏报,能提高驾驶体验。
