  "textContent": "A method for controlling a traction control system, ABS and actively controlled suspension. The method includes receiving an sensor output from at least one suspension sensor at a controller. The sensor output is indicative of a vertical height of the suspension relative to a road. The method determines an amplitude of vertical motion of the suspension over time using the received sensor output. The method identifies peaks and valleys in the amplitude of vertical motion of the suspension over time. The method determines that a rough road condition is present in response to a number of peaks and valleys exceeding a predefined threshold amplitude occurring more often than a predefined threshold frequency. An active suspension control of at least one wheel system of a vehicle is adapted in response to determining that a rough road condition is present.",
