A trailer ABS uses a vehicle velocity calculated by the tractor to augment the vehicle velocity that is calculated by the trailer alone. As a result, the trailer ABS calculates vehicle velocity more accurately. The improved trailer velocity data permits optimum trailer ABA performance. Specifically, the trailer ABS preferably includes at least one wheel velocity sensor that generates a trailer wheel velocity signal indicative of a reference trailer velocity, an electronic control unit that generates a corrected trailer velocity based on a tow vehicle velocity and the trailer wheel velocity signal, a trailer brake system, and an antilock modulation device coupled to the electronic control unit the trailer brake system. The control unit controls the activate of the antilock modulation device based on the corrected trailer velocity.
