Abstract
A method for operating a driver assistance system for a vehicle includes capturing a video feed of an external environment of the vehicle and transmitting the video feed to an Electronic Control Unit (ECU) of the vehicle. Subsequently, a designated speed limit for the vehicle at a current location of the vehicle is determined. The method further includes extracting context information of the external environment from the video feed and comparing the context information to the designated speed limit to create a contextual speed limit. A user is notified of the vehicle of the contextual speed limit. The context information designates a specific environment that the vehicle is located in based upon one or more of: first warning information that informs the user of unsafe driving conditions, first guidance information that provides directional information to the user, and objects located in the specific environment of the vehicle.
