1. A method of controlling a front corner suspension and a diagonally opposed rear corner suspension in a vehicle having a brake system with two front corner brakes and brake control means effective at times to modify vehicle yaw rate by applying a greater braking force to one of the front corner brakes adjacent the front corner suspension than to the other of the front corner brakes and generate an active brake signal while so doing, the method comprising the steps:

  • receiving the active brake signal;

    determining a relative velocity of the front corner suspension and a relative velocity of the diagonally opposed rear corner suspension;

    determining a compression damping command for the front corner suspension and a rebound damping command for the diagonally opposed rear corner suspension;

    while the signal is received, applying the compression damping command to the front corner suspension when the relative velocity thereof indicates that it is in compression; and

    while the signal is present, applying the rebound damping command to the diagonally opposed rear corner suspension when the relative velocity thereof indicates that it is in rebound.
