Dynamic throttle pedal filtering of a vehicle is provided. An automated throttle filtering system may be included in the vehicle that may operate to filter throttle pedal input based on detection of a rough driving surface. The rough driving surface detection may be based on an evaluation of wheel speed signals or an indication of traction loss. The throttle pedal input may be filtered corresponding to rough driving surface magnitude values determined based on the wheel speed signals. For example, filtered torque demand values may be determined based on the rough driving surface magnitude values and included in a torque demand request communicated to the vehicle's poweitiain system. The resulting torque output may modulate an undesirable oscillating torque demand that may be generated in relation to operation of the vehicle on a rough driving surface.
