Embodiments herein relate to robust methodologies for autonomous parking. In one or more embodiments, an autonomous vehicle may determine the slope of a road based upon one or more inputs and a pre-defined slope definition and may also determine curb/no curb status of a parking location. Given the determined road conditions, such as slope and no curb/curb, embodiments determine wheel direction and angle that the vehicle should achieve to properly park. Embodiments also include countermeasures if one or more issues prohibit the vehicle from achieving a desired parking condition.
