Methods and apparatuses for vehicle wading safety
First Claim
1. A method, comprising:
- determining, by a processor, one or more aspects of a waterbody;
calculating, by the processor, one or more critical trajectories of a vehicle wading the waterbody based at least in part on the one or more aspects;
determining, by the processor, whether it is safe for the vehicle to wade the waterbody based on the one or more critical trajectories and the one or more aspects; and
estimating, by the processor, a speed of a current of the waterbody based on input from one or more above-water sensors disposed on the vehicle, the one or more above-water sensors configured to track a floating object carried by the current,wherein the determining of whether it is safe for the vehicle to wade the waterbody is further based on the speed of the current and a buoyancy model of the vehicle.

Abstract
Techniques and examples pertaining to vehicle water wading safety are described. A processor implementable to a vehicle approaching a waterbody may receive data related to the waterbody from one or more above-water or under-water sensors. The processor may determine a top surface and a bottom profile of the waterbody, and calculate one or more critical trajectories of water-sensitive components of the vehicle if the vehicle is to wade through the waterbody by traversing the bottom profile. The processor may then determine the wading safety based on the critical trajectories and the top surface of the waterbody. The processor may further determine a wading route, and autonomously drive the vehicle to wade the waterbody via the optimal wading route.

13. An apparatus, comprising:
-
a memory capable of storing one or more sets of instructions and a spatial model of a vehicle; and a processor coupled to execute the one or more sets of instructions stored in the memory such that, upon executing the one or more sets of instructions, the processor performs operations comprising; determining one or more depths and a bottom profile of a waterbody, via a sensor; calculating one or more critical trajectories of the vehicle based on the bottom profile of the waterbody and the spatial model of the vehicle; determining whether it is safe for the vehicle to wade the waterbody based on the one or more depths of the waterbody and the one or more critical trajectories; and performing, via a navigation device either; determining a wading route via which the vehicle is able to wade through the waterbody safely and a wading speed at which the vehicle is able to wade through the waterbody safely via the wading route;
ordetermining an alternative route via which the vehicle is able to avoid the waterbody. - View Dependent Claims (14, 15, 16, 17)
