Abstract
An example vehicle system for automated mitigation of rough road conditions includes front wheels, a steering linkage, a torque sensor, and a vehicle control module configured to obtain a torque signal from the torque sensor, calculate a first average length value for the torque signal according to a first sampling frequency, calculate a first average variance value for the torque signal, calculate a second average length value for the torque signal according to a second sampling frequency, calculate a second average variance value for the torque signal, determine whether a rough road condition threshold is satisfied according to the first average length value, the first average variance value, the second average length value and the second average variance value, and automatically adjust at least one of vehicle acceleration, vehicle braking or vehicle steering, in response to the rough road condition threshold being satisfied.
