Lane-dependent navigation guidance for one vehicle

Abstract

A system for guiding a vehicle's route based on road surface characteristics, wherein the system comprises: a global navigation satellite system (GNSS) to determine the vehicle's geographic location; a vehicle communication system for communication with at least one external system; and a vehicle controller in electrical communication with the GNSS and the vehicle communication system, wherein the vehicle controller is programmed to: Determining the vehicle length and vehicle width; Receiving a navigation request from a vehicle occupant; and Determining a navigation route using at least the GNSS and the vehicle communication system in response to receiving the navigation request, wherein the navigation route is based at least partially on the vehicle length and vehicle width, and wherein, in order to determine the navigation route, the vehicle controller is further programmed to: Determining the geographical location of the vehicle using GNSS; Sending the vehicle's geographic location, navigation request, vehicle length, and vehicle width via the vehicle communication system to a server controller; and Receiving the navigation route from the server controller using the vehicle communication system, the server controller being programmed to: Determining a multitude of possible routes, at least partially, based on the geographical location of the vehicle, with each of the multitude of possible routes fulfilling the navigation requirement; Determining a route lane comfort score for each of the multitude of possible routes; and Selecting the navigation route from the multitude of possible routes, at least partially based on the route lane comfort value for each of the multitude of possible routes, wherein the server controller is further programmed to determine the route lane comfort value for each of the multitude of possible routes: Retrieving the lane width and lane curve radius for each of a multitude of points along the multitude of possible routes from a database, the database being in electrical communication with the server controller; Determining a point-lane comfort score for each of the multitude of points along each of the multitude of possible routes, at least partially based on the lane width and lane curve radius for each of the multitude of points, as well as the vehicle length and vehicle width; and Determining the route lane comfort score for each of the multitude of possible routes by summing the point lane comfort score for each of the multitude of points along each of the multitude of possible routes.
