Boat trailer water level detection system

1. A system for monitoring a water level proximate to a vehicle, the system comprising:

a control unit;

at least one sensor in communication with the control unit, wherein the at least one sensor is configured such that the control unit can determine in real time:

a pitch of a trailer coupled to the vehicle; and

a height of a surface of water proximate to the trailer; and

a display screen controlled by the control unit to display a real time image simultaneously comprising:

a side-view graphical representation of the trailer including the pitch of the trailer; and

a cross-sectional graphical representation of the surface of water proximate to the trailer.

2. The system of claim 1 , wherein the at least one sensor comprises at least one of a camera, radar, lidar, sonar, RF shadow, proximity, infrared, moisture, immersion, depth, weight, acceleration, or inclination sensor.

3. The system of claim 1 , wherein the at least one sensor is further configured such that the control unit can determine in real time a pitch of the vehicle and a position of the vehicle relative to the trailer and the surface of water, and wherein the display screen further simultaneously displays a real-time side-view graphical representation of the vehicle including the pitch of the vehicle.

4. The system of claim 1 , wherein the at least one sensor is further configured such that the control unit can determine in real time, for a watercraft on or proximate to the trailer, a location and pitch relative to the trailer and the surface of water, and wherein the display screen further simultaneously displays a real-time side-view graphical representation of the watercraft, including the location or pitch of the watercraft relative to the trailer and the surface of water.

5. The system of claim 4 , wherein the control unit is further configured to display a real-time indication that the watercraft is floating if the location or pitch relative to the trailer is outside a threshold range.

6. The system of claim 1 , wherein the at least one sensor comprises a weight sensor configured to measure in real time a weight of a watercraft on the trailer, and

wherein the control unit is further configured to display a real time indication that the watercraft is floating if the measured weight is less than a threshold amount.

7. The system of claim 1 , wherein the display screen is a portable device or vehicle head unit.

8. The system of claim 1 , further comprising the vehicle.

9. The system of claim 1 , further comprising the trailer.

10. The system of claim 1 , further comprising a watercraft positionable on the trailer.

11. A method comprising:

in a control unit, receiving sensor data from at least one sensor;

based on the sensor data, determining in real time a pitch of a trailer coupled to a vehicle; and

a height of a surface of water proximate to the trailer; and

displaying, on a display screen controlled by the control unit, a real time image simultaneously comprising:

a side-view graphical representation of the trailer including the pitch of the trailer; and

a cross-sectional graphical representation of the surface of water proximate to the trailer.

12. The method of claim 11 , wherein the at least one sensor comprises at least one of a camera, radar, lidar, sonar, RF shadow, proximity, infrared, moisture, immersion, depth, weight, acceleration, or inclination sensor.

13. The method of claim 11 , further comprising:

determining in real time a pitch of the vehicle and a height of the vehicle relative to the surface of water; and

displaying in real time a side-view graphical representation of the vehicle including the pitch of the vehicle simultaneously with the side-view graphical representation of the trailer and the cross-sectional graphical representation of the surface of water.

14. The method of claim 11 , further comprising:

determining in real time, for a watercraft on or proximate to the trailer, a location and pitch relative to the trailer and the surface of water; and

displaying in real time a side-view graphical representation of the watercraft, including the location or pitch of the watercraft relative to the trailer and the surface of water simultaneously with the side-view graphical representation of the trailer and the cross-sectional graphical representation of the surface of water.

15. The method of claim 14 , further comprising displaying a real-time indication that the watercraft is floating if the location or pitch relative to the trailer is outside a threshold range.

16. The method of claim 11 , wherein the at least one sensor comprises a weight sensor configured to measure a weight of a watercraft on the trailer, and wherein the method further comprises displaying an indication that the watercraft is floating if the measured weight is less than a threshold amount.

17. The method of claim 11 , wherein the display screen is a portable device or vehicle head unit.

18. The method of claim 11 , wherein the control unit is associated with the vehicle, the trailer, or a watercraft positionable on the trailer.

19. A system for monitoring water level proximate to a vehicle, the system comprising:

a control unit;

at least one sensor in communication with the control unit, wherein the at least one sensor is configured such that the control unit can determine in real time a depth of the vehicle within a body of water and a pitch of a trailer towed by the vehicle; and

a display screen disposed within a dashboard of the vehicle and controlled by the control unit to display a real time image comprising a side-view graphical representation of the depth of the vehicle in the body of water and the pitch of the trailer towed by the vehicle.

20. The system of claim 19 , further comprising an audible tone controlled by the control unit, wherein the audible tone is indicative of the depth of the vehicle in the body of water.
