A work vehicle is configured for visually representing an area of interest such as the blade of a work implement. A first portion (e.g., frame) includes an operator cab and a second portion (e.g., boom assembly) is moveable relative to the first portion, wherein the area of interest is at least partially obscured from operator view during movement of the second portion. An imaging device is mounted on the second portion and has a field of view including the area of interest throughout the movement of the second portion. During a first operating mode, a display unit is caused to statically display an area around the area of interest while the area of interest moves along with movement of the second portion. During a second operating mode, the display unit is caused to statically display the area of interest while the background moves along with movement of the second portion.

Work vehicle having controlled transitions between different display modes for a moveable area of interest

A body swing collision avoidance system and method for a machine with steerable traction devices for moving the machine. Sensors monitor obstacles around the machine. A commanded body swing path is calculated based on operator steering commands. If an obstacle is in the commanded body swing path, the system automatically adjusts the steering commands to avoid collision with the obstacle. A time to collision can be calculated, and the steering commands adjusted only when it is below a threshold. Adjusting the steering commands to avoid collision can include determining propel and steer components based on the steering commands; and if propel is greater than a threshold then adjusting the steering commands to adjust the swing path to avoid collision; and if propel is less than the threshold then adjusting the steering commands to slow the machine to avoid collision.
