  • Method for determining trailer braking output
    Patent number: 8165768
    Abstract: A method for providing a trailer equipped with trailer brakes with an electronically controlled trailer braking output to help slow a vehicle/trailer combination as quickly as possible, but in a stable and balanced manner. In situations where a low friction environment is detected, such as a wet or icy road, the present method can brake the trailer in a more aggressive manner than a gain setting would normally allow. This gain-independent segment of the trailer braking output can result in a shorter stopping distance for the vehicle/trailer combination, without causing excessive trailer wheel lockup.
