Vehicle systems and methods for automated mitigation of rough road conditions

A method for automated mitigation of rough road conditions, the method:

• obtaining a torque signal from a torque sensor coupled with a steering linkage of a vehicle, wherein the vehicle includes front wheels, the steering linkage is coupled with the front wheels of the vehicle, and the steering linkage is configured to control a steering orientation of the front wheels;
• calculating a first average length value for the torque signal according to length fractal dimensions of the torque signal at a first sampling frequency;
• calculating a second average length value for the torque signal according to length fractal dimensions of the torque signal at a second sampling frequency, wherein the second sampling frequency is less than the first sampling frequency;
• determining whether a rough road condition threshold is satisfied according to the first average length value, and the second average length value;
• and
• automatically adjusting at least one of vehicle acceleration, vehicle braking or vehicle steering, in response to the rough road condition threshold being satisfied.
