Abstract: A trailer assembly includes first and second axles supporting first and second wheels which are coupled to first and second actuators of a steering system. The steering system includes a control circuit connected to the actuators and the control circuit includes a driving device configurable in a low speed maneuvering mode with: a synchronized sub-mode in which the actuators can be actuated in a synchronized manner to steer the wheels in a synchronized manner, and a desynchronized sub-mode in which the first and second actuators can be actuated individually and independently to steer only the first wheels or only the second wheels. A control device is connected to the driving device to: select one of the sub-modes in the low speed maneuvering mode, and select an actuation either of the first actuator or of the second actuator, in the desynchronized sub-mode.
