In accordance with various embodiments, methods, systems, and vehicles are provided for determining an environment of vehicles. In one embodiment, a vehicle includes a body, a plurality of sensors, and a processor. The plurality of sensors are disposed onboard the vehicle, and is configured to at least facilitate transmitting signals from a vehicle and receiving return signals at the vehicle after the transmitted signals have contacted one or more objects. The processor is disposed onboard the vehicle, and is coupled to the plurality of sensors. The processor is configured to at least facilitate identifying one or more parameters of the return signals; comparing the one or more parameters with historical data stored in a memory; and determining an environment of the vehicle based at least in part on the comparison of the one or more parameters with the historical data.
