1. A method, comprising:
obtaining predicted driving condition data from a database, wherein the database comprises one or more of geospatial data and remote vehicle data, wherein the one or more of the geospatial data and the remote vehicle data comprise at least predicted road orientation and topography, road banking, and cross-wind data for a geographical area;
obtaining real-time vehicle state data from equipment communicatively connected to a vehicle, wherein the real-time vehicle state data comprises at least vehicle speed, attitude, and side-force data;
weighting the predicted driving condition data and the real-time vehicle state data based on a confidence associated with each;
combining the weighted predicted driving condition data and the real-time vehicle state data to formulate a desired steering torque request necessary to compensate for predicted and actual driving conditions experienced by the vehicle potentially causing or causing undesirable side-force on the vehicle; and
providing the desired steering torque request to a power steering assist system of the vehicle to compensate for the predicted and actual driving conditions experienced by the vehicle thereby counteracting the undesirable side-force on the vehicle before or as the undesirable side-force on the vehicle occurs.
