1. A towing vehicle controller for providing brake control of a towed vehicle comprising:

  • a controller load input for receiving a load signal indicative of a sensed load of a towed and towing vehicle combination;

    a controller stability input for receiving a stability signal indicative of at least one of a sensed yaw rate, a sensed steering angle and a sensed lateral acceleration of the towing vehicle;

    a controller deceleration input for receiving a deceleration signal indicative of an automated deceleration request; and

    control logic capable of;

    determining an empirical load value based on the load signal;

    determining an empirical stability value based on the stability signal;

    determining a comparison value is the empirical load value when the stability signal is less than a predetermined stability threshold, and the comparison value is the empirical stability value when the stability signal is greater than or equal to the predetermined stability threshold; and

    determining a brake control transmission signal after receiving a deceleration signal, wherein the determination is based on the deceleration signal and the comparison value.
