Abstract

A system and method for automated vehicle control includes: referencing map-based attributes related to autonomous vehicle GPS coordinates; establishing control points based on map-based attributes; and controlling the autonomous vehicle to a control point by at least one of the steering system, the braking system, and the powertrain system.

Description

technical field [0001] The present disclosure relates to situation awareness and automatic vehicle control for road vehicles. Background technique [0002] Known perception systems monitor the area around the vehicle to improve the vehicle's situational awareness, such as forward and reverse range, range rate, and vision systems. Such perception systems can be used to provide operator alerts and control inputs related to infrastructure and objects, including other vehicles. Such systems can be enablers in various levels of automated vehicle control, such as adaptive cruise control, assisted parking, lane keeping, and self-navigation. [0003] Perception and mapping systems can be used in conjunction with other technologies such as GPS, odometers, and inertial measurements for vehicle localization, as well as other underlying map layers including feature and attribute data. This combination of technologies is useful in trip routing and higher levels of automatic vehicle con...
