Detecting untraversable environment and preventing damage by a vehicle
A vehicle moves through an environment (e.g., a farming, construction, mining, or forestry environment) and performs one or more actions in the environment. Portions of the environment may include moisture, such as puddles or mud patches. A control system associated with the vehicle may include a traversability model or a moisture model to help the vehicle operate in the environment with the moisture. In particular, the control system may employ the traversability model to reduce the likelihood of the vehicle attempting to traverse an untraversable portion of the environment, and the control system may employ the moisture model to reduce the likelihood of the vehicle performing an action that will damage a portion of the environment.
1. A method for operating in a construction environment with moisture by a construction vehicle, the method comprising:

determine a likelihood that the construction vehicle performing the identified construction action will enlarge a water run-off channel or form a water run-off channel in the portion of the construction environment based on the identified construction action and the determined measure of moisture for the portion of the construction environment; and
responsive to the likelihood that the construction vehicle performing the identified construction action will enlarge the water run-off channel or form the water run-off channel in the portion of the construction environment exceeding a threshold likelihood, perform a second construction action, wherein a likelihood that the construction vehicle performing the second construction action will enlarge the water run-off channel or form the water run-off channel in the portion of the construction environment is less than the threshold likelihood.
13. The construction vehicle of claim 12 , wherein the second construction action is performed instead of the identified construction action.
14. The construction vehicle of claim 12 , wherein the second construction action comprises nullifying the identified construction action such that the identified construction action is not performed as the construction vehicle moves along the route.
15. The construction vehicle of claim 12 , wherein the second construction action includes at least one of: modifying the route or modifying a driving parameter of the construction vehicle.
16. The construction vehicle of claim 12 , wherein determining the likelihood that the identified construction action will enlarge the water run-off channel or form the water run-off channel in the portion of the construction environment is further based on the route.
17. The construction vehicle of claim 12 , determining the likelihood that the identified construction action will enlarge the water run-off channel or form the water run-off channel in the portion of the construction environment is further based on diagnostic information from one or more sensors of the construction vehicle.
18. The construction vehicle of claim 12 , wherein determining the likelihood that the identified construction action will enlarge the water run-off channel or form the water run-off channel in the portion of the construction environment is further based on characteristics describing the construction vehicle, the characteristics including at least one of: a wheel type, a wheel size, a tread type, an engine/motor type, a drive type, a make, a model, a weight, a fuel level, a treatment mechanism, or a coupling mechanism of the construction vehicle.
