A system and method for braking a towed vehicle

A system and method for braking a towed vehicle. In a preferred embodiment, a system is provided for use on a trailer 102 having an axle assembly 108. The system 100 includes a motor controller 124, a pair of electric motor/generators 120, a battery 122, a battery controller 126, and sensors 128. Controller 124 monitors the yaw rate of trailer 102 by use of sensors 128. Based upon the monitored yaw rate, controller 124 selectively activates motor/generators 120 which provide a regenerative braking torque to axle assembly 108, thereby braking trailer 102 and generating electrical energy which may be used to recharge battery 122.
