  • Patent number: 8215436
    Abstract: A system and related method for a regenerative braking system on a towed vehicle, such as a trailer or semi-trailer. The system provides power and braking to the respective trailer wheels, as needed, to help stabilize the trailer. Power is regenerated during braking. While batteries may be used to store the energy, the system also may use capacitive storage units, which charge and discharge large amounts of energy at a fast rate. A multiple-axis sensor system in conjunction with wheel sensors, load sensors, and proportional control of the brakes and motor power to the axles and wheels, is used to achieve superior load stabilization. The invention can be easily retrofit into new or used trailers, and is self-contained with low maintenance.
