1. An improved Electronic Stability Control system for a vehicle comprising:

  • a map database that includes data that indicates properties of roads in a road network upon which the vehicle travels;

    a positioning system operably coupled to the map database to determine a position of the vehicle on a road in the road network;

    an electronic control unit comprising a processor operable to execute programming functions, wherein said electronic control unit is operably coupled to sensors that indicate a vehicle direction and a steering wheel position, and further wherein said electronic control unit is operably coupled to the positioning system to receive information indicating the position of the vehicle on the road, and wherein said electronic control unit includes outputs to brake actuators associated with brakes associated with individual wheels of said vehicle; and

    a ESC program run on the electronic control unit that uses inputs from the sensors and information from the map database that indicates a property of the road upon which the vehicle is located to determine whether to provide an output to the brake actuators to reduce a difference between an intended vehicle direction and an actual vehicle direction.
