Abstract
A traction controller which modulates brake pressure to prevent excessive wheel spin in each of the driven wheels of a vehicle senses a side to side spin cycling condition of the driven wheels and increases the brake pressure of the driven wheel having the lesser of the two driven wheel brake pressures to a larger percentage of the other driven wheel brake pressure to inhibit the side to side spin cycling condition. The side to side spin cycling condition is represented by one driven wheel accelerating with a positive jerk value while the other driven wheel is decelerating with a negative jerk value.
