The invention discloses a vehicle wading auxiliary early warning system and early warning method, and relates to the field of vehicle wading detection. The system comprises a water volume sensor whichis used for generating a starting signal when a vehicle wades, and detecting the wading depth so as to output a first water depth signal, an accumulated water scene recognition device which is used for detecting the water depth within a preset distance range in front of the accumulated water scene recognition device and outputting a second water depth signal, and a controller which is used for correspondingly setting a multi-stage water depth threshold range based on an intake demand parameter of the vehicle, configuring an early warning mode corresponding to each stage of water depth threshold range, receiving the first water depth signal and the second water depth signal, judging whether the first water depth signal and/or the second water depth signal are/is within one of a plurality of preset water depth threshold ranges or not, and outputting a corresponding alarm if the first water depth signal and/or the second water depth signal are/is within one of the plurality of preset water depth threshold ranges. According to the invention, various influence factors can be comprehensively considered, and a better early warning effect is achieved by setting a multi-stage early warningmode.
本发明公开了一种车辆涉水辅助预警系统及预警方法,涉及车辆涉水检测领域,包括水量传感器,其用于在车辆涉水时生成启动信号,并检测涉水深度以输出第一水深信号;积水场景识别装置,积水场景识别装置用于检测其前方预设距离范围的水深,并输出第二水深信号;控制器,其基于车辆的进气需求参数,对应设置多级水深阈值范围,并配置与每一级水深阈值范围对应的预警方式,控制器用于接收第一水深信号和第二水深信号,并判断第一水深信号和/或第二水深信号是否在多个预设的水深阈值范围之一内,若在多个预设的水深阈值范围之一内,则输出对应的告警。本发明能综合考虑多方面影响因素,并通过设置多级预警的方式以起到较好的预警效果。
