Abstract: A vehicle having a system for determining that there is a possibility that the vehicle has or is about to enter water at a vehicle wading depth. In response to determining that there is a possibility that the vehicle has or is about to enter water at a vehicle wading depth, the system is configured to implement one or more vehicle control strategies. The system comprises at least one remote sensor configured to remotely detect the presence of water about or ahead of the vehicle.

Abstract: A predictive method of detecting the depth of water ahead of a wading vehicle comprises providing a wading sensor and an attitude sensor on the vehicle, and using this information to estimate the depth of water at a location ahead of the direction of vehicle movement. Corresponding apparatus is disclosed.

Abstract: A method of controlling an HMI-apparatus for providing information comprising comparing data from two or more remote-ranging sensors disposed at an elevation greater than the threshold wading depth of the vehicle.

Abstract: A vehicle having a system for determining that there is a possibility that the vehicle has entered or is about to enter water at a vehicle wading depth. The system comprising at least one under-body mounted sensor both configured to remotely and directly detect the presence of water substantially below and about the under-body mounted sensor. The under-body mounted sensor may be an ultrasound transducer sensor both configured to estimate a depth of water the surface of which is substantially below the sensor and to detect the presence of water when the sensor is in contact with water. In response to determining that there is a possibility that the vehicle has entered or is about to enter water at a vehicle wading depth, the system is configured to implement one or more vehicle control strategies.

Abstract: A vehicle (100) comprises a plurality of water level sensors, for example comprising capacitive or resistive sensors, from the outputs of which can be determined vehicle orientation when wading. In conjunction with a vehicle orientation sensor, the outputs from any one water level sensor permits calculation of water depth at any point on the vehicle body.

Abstract: The present invention relates to a method of determining a wade depth (dMax) in relation to a vehicle (1) when at least partially submerged in water. An attitude of the vehicle (1) is determined and a first height (dSensed) of the surface of the water measured relative to a first reference point on the vehicle (1). The wade depth (dMax) is determined based on the attitude of the vehicle (1) and said first height (dSensed). Alternatively, or in addition, the travel height (HS) of a vehicle suspension is determined. Aspects of the invention also relates to a system and a vehicle (1).

Abstract: A vehicle (100) comprising a wading information display (1020) and a wading depth sensor, the display showing an elevation of a vehicle on which is superimposed the current wading depth. The display may also indicate simultaneously the maximum wading depth calculated according to the ride height of the vehicle, the inclination of the vehicle by inclination of the displayed elevation, and an advisory speed according to wading depth and/or vehicle inclination.

Abstract: A predictive method of detecting the depth of water ahead of a wading vehicle comprises providing a wading sensor and an attitude sensor on the vehicle, and using this information to estimate the depth of water at a location ahead of the direction of vehicle movement. Corresponding apparatus is disclosed.

Abstract: 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.

Abstract: A vehicle comprises a driver display on which is displayed an advisory maximum wading speed according to the current wading depth of the vehicle. The advisory speed is in one embodiment displayed on the vehicle speedometer. The display may also include an elevation of a vehicle on which is indicated one or more of maximum wading depth, current wading depth and vehicle inclination.

Abstract: A vehicle (100) comprises a water depth sensing apparatus (114) comprising a capacitive resistive sensor.

Abstract: A vehicle having a wading sensor may include a control unit adapted to implement an alternative or modified vehicle control strategy during wading. The wading strategy may change many vehicle functions, alone or in combination, and may be further responsive to depth of wading.

Abstract: A vehicle (100) comprising a wading information display (1020), a memory and a processor, the memory containing a program configured to run on the processor to calculate the maximum wading depth of the vehicle from the measured suspension travel, and to display the maximum wading depth on the display. The display may also show a dual wading depth, an advisory wading speed, and vehicle inclination.

Abstract: A wading sensor for a vehicle comprises an ultrasonic parking distance control. An embodiment detects wading by sensing the difference in the settling time of the diaphragm of a transmitter/receiver, in water and in air. Other embodiments are disclosed.

Abstract: A wading vehicle (100) having a water level sensor (114) comprising a hydrostatic pressure sensor.
