A rear wheel steering (RWS) control method for a cargo trailer, the RWS control method comprising:
- determining a driving mode of a vehicle connected to the cargo trailer;
- executing a RWS control logic of the cargo trailer based on the driving mode and an input signal from the vehicle, a length of a tow bar, a cosine of an angle between the tow bar and a connecting shaft, a length of a coupler and a cosine of an angle between the coupler and the connecting shaft corresponding to the driving mode;
- and
- performing RWS control for the cargo trailer based on the RWS control logic.
