Abstract
The present disclosure provides systems and methods for automatically controlling braking and/or wheel speed at a dolly to increase maneuverability. In one form, a system comprises a memory, a first sensor, and at least one processor. The first sensor is configured to determine at least one of a distance from a dolly to a forward trailer or an angle from the dolly to the forward trailer. The at least one processor is configured to: determine that a forward trailer is moving in a reverse direction; determine a steering angle of a vehicle coupled to the forward trailer; measure a rotation of the forward trailer based on information received from the first sensor; and apply at least one of braking or wheel speed control to at least one wheel of the dolly based on the measured rotation of the forward trailer and the determined steering angle of the forward trailer.
