Abstract
A system may include a sensor that detects positioning data indicative of a position of a first coupler of a first vehicle system and positioning data indicative of a position of a second coupler of a second vehicle system during a coupling event of the vehicle systems. A controller includes one or more processors that receive the positioning data of the first and second couplers and determines whether the first coupler is misaligned with the second coupler. The controller may initiate an action of the first coupler, the second coupler, the first vehicle system, or the second vehicle system to change a position of the first coupler, the second coupler, the first vehicle system, or the second vehicle system. Changing the position of the first coupler, the second coupler, the first vehicle system, or the second vehicle system aligns the first coupler with the second coupler.
