Abstract
A system and method for braking a towed conveyance. In one embodiment, a system is provided for use on a trailer ( ) having an axle assembly ( ). The system ( ) includes a motor controller ( ), a pair of electric motor/generators ( ), a battery ( ), a battery controller ( ), and sensors ( ). Controller ( ) monitors the yaw rate of trailer ( ) by use of sensors ( ). Based upon the monitored yaw rate, controller ( ) selectively activates motor/generators ( ) which provide a regenerative braking torque to axle assembly ( ), thereby braking trailer ( ) and generating electrical energy which may be used to recharge battery ( ).
