1. A trailer sideswipe avoidance system for a vehicle towing a trailer in a forward direction, comprising:
a sensor system configured to detect an object in an operating environment of the vehicle;
a controller that processes information received from the sensor system to determine whether the object detected in the operating environment of the vehicle is in a forward travel path of the towed trailer as the vehicle turns via:
determining the travel path of the forwardly towed trailer as the vehicle turns; and
determining whether the object detected in the operating environment of the vehicle is in the travel path of the forwardly towed trailer by determining whether an inner trailer boundary line intersects a virtual circle having a center point at a trailer turn center and a radius equal to a distance from the trailer turn center to the object; and
a visual display that displays bird's eye view representations of the vehicle and the trailer and a collision warning band that extends around at least a portion of the bird's eye view representation of the trailer, wherein a portion of the collision warning band changes color based on the controller determining that the object is in the travel path of the towed trailer, wherein a position, relative to the bird's eye view representation of the trailer, of the portion of the collision warning band that changes color corresponds with an intersection point of the inner trailer boundary line and the virtual circle.
