Abstract
A method for controlling wheel hop at a vehicle axle includes determining that one of a difference between average front and rear wheel speeds exceeds a reference difference, a frequency of a signal produced by an accelerometer mounted on the axle exceeds a reference frequency, and a frequency of a lock ring torque exceeds a second reference frequency; pulsing pressure in the wheel brakes of the axle; and reducing engine torque.
