Abstract: An air brake controller system for a vehicle trailer associated with a vehicle enables an air brake system of the trailer to be controlled via teleoperation control signals when the vehicle is teleoperated. The air brake controller system comprises a wireless communication device to wirelessly receive brake control signals from the vehicle or directly from a remote teleoperation system. An on-board computer of the air brake controller system processes the brake control signals to generate one or more valve control signals that controls flow of air from a compressed air reservoir into air lines connected to the air brake system of the trailer.
