  • Method and apparatus for speed estimation and control
    Patent number: 9187097
    Abstract: A system and method for determining a speed profile for a vehicle travelling along a road in which a curve speed estimation unit receives inputs indicating a position of the vehicle relative to a curve ahead of the vehicle, and inputs related to vehicle velocity, curve geometry, road surface conditions, vehicle-specific data; and driver preferences. The curve sped estimation unit use at least some of the above-listed inputs to determine a speed profile for the curve by generating an acceleration limit map which depends on a relationship between a maximum possible longitudinal acceleration and a maximum possible lateral acceleration.
