Claim of US Patent No. 9,321,320

1. A method of controlling a vehicle suspension for a wheel via a controller, the method comprising:
repeatedly calculating a vertical velocity of the wheel until the vertical velocity exceeds a first velocity threshold;
in response to the vertical velocity exceeding the first velocity threshold, initiating a timer and maintaining a damping
level of an adjustable damping mechanism of the vehicle suspension at an initial value while repeatedly recalculating the
vertical velocity of the wheel until a recalculated vertical velocity exceeds a second velocity threshold; and

in response to the recalculated vertical velocity exceeding the second velocity threshold before the timer exceeds a first
time threshold, sending an adjustment signal to the adjustable damping mechanism of the vehicle suspension to increase the
damping level of the suspension.
