1. In an antiskid control system for a braked wheel vehicle wherein the system includes a brake on a wheel, a control valve regulating pressure at the brake, and a control circuit connected to the control valve and applying thereto an antiskid control signal, the improvement, comprising:

  • first means comprising a first amplifer having variable gain, said first means being connected to the brake for producing an output signal corresponding to the brake pressure at the brake;

    second means connected to the vehicle for producing an output signal analogous to the torque of the brake;

    summing means interconnected between said first and second means for receiving and summing said output signals therefrom; and

    modification means for receiving both the antiskid control signal and the sum of said output signals from said summing means, said modification means modifying the antiskid control signal as a function of said sum and then supplying the modified antiskid control signal to the control valve.
