Computer-implemented techniques include determining, at a controller of a vehicle, a wheel speed for each of two front wheels of the vehicle and two rear wheels of the vehicle. The techniques include calculating, at the controller, a difference between (i) an average of the wheel speeds for the two front wheels of the vehicle and (ii) an average of the wheel speeds for the two rear wheels of the vehicle to obtain an error. The techniques include setting, at the controller, a rough road detection bit when the error is greater than or equal to a threshold indicative of an error corresponding to rough road. The techniques include monitoring, at the controller, the rough road detection bit for a period to obtain a hysteresis band. The techniques also include determining, at the controller, whether the vehicle is traveling on rough road based on the hysteresis band.
