Various embodiments of a towing vehicle controller and methods for brake control of a towed vehicle are provided. A towing vehicle controller includes an input for receiving a load signal indicative of a load of a towed and towing vehicle combination; an input for receiving a stability signal indicative of at least one of a yaw rate, a steering angle, and a lateral acceleration of the towing vehicle; and an input for receiving a deceleration signal indicative of an automated deceleration request. Control logic is capable of determining a comparison value prior to receiving the deceleration signal and after receiving the load signal and the stability signal, wherein the determination of the comparison value is based on the load signal and the stability signal. After the deceleration signal is received, the control logic determines a brake control transmission signal based on the deceleration signal and the comparison value.
