WADING DETECTION SYSTEM FOR A VEHICLE

摘要

A wading indicator system for a vehicle comprising: at least one sound wave pulse emitter device; at least one sound wave pulse receiver device; and a control unit. The control unit configured to measure one or more of the following variables: (i) the time of flight of a sound pulse between the at least one sound wave pulse emitter device and the at least one sound wave pulse receiver device; (ii) the amplitude of a sound pulse emitted by the at least one sound wave pulse emitter device when received by the at least one sound wave pulse receiver device; and (iii) the wavelength of a sound pulse emitted by the at least one sound wave pulse emitter device when received by the at least one sound wave pulse receiver device. Thereby the control unit is configured to determine whether at least a portion of the vehicle is immersed in water.
