Abstract
The present disclosure is directed to an obstacle awareness device for vehicle systems. A threshold distance is set that identifies the range at which an obstruction interferes with fluid dynamics around and through at least one propulsion motor. One or more ranging sensors on the vehicle system detect relative position information of the obstruction when it is within the threshold distance. The relative position information is communicated to a controller, which adjusts a motor control signal to compensate for the obstruction interfering with the fluid dynamics around the at least one propulsion motor. The threshold distance may be defined by a three dimensional shape that encapsulated the vehicle system, and the three dimensional shape may change in shape or size with movement of the vehicle system.
