A processor-implemented path planning method in a vehicle is disclosed. The method includes retrieving road surface information along a planned path for the vehicle; constructing, by the processor, a model of the road surface along the planned path; identifying, by the processor, a road irregularity in the road surface for the planned path; classifying, by the processor, the road irregularity; projecting the location of vehicle tire patches on the model of the road surface; predicting, by the processor, vehicle sprung-mass dynamics as a function of time for the vehicle along the planned path; calculating a plurality of alternative path trajectories within the constraints of the road boundaries for avoiding the road irregularity; choosing an alternative path trajectory out of the plurality of alternative path trajectories that reduces the sprung-mass dynamics for the vehicle to provide a more comfortable ride; and updating the planned path with the chosen alternative path trajectory.
