摘要： A fuel saving-aimed motor vehicle driver assistance system configured to receive and process motor vehicle-related data and motor vehicle position-related data to identify recurrent routes of a motor vehicle and to provide a motor vehicle driver, via an automotive human-machine interface, with motor vehicle driving assistance recommendations for fuel saving along the routes. The motor vehicle driver assistance system is configured to identify recurrent routes of the motor vehicle by determining a succession of geographic points, referred to as Waypoints, along a route of the motor vehicle, at which values of a series of physical quantities are determined and recorded, which define the attributes of the Waypoints. The Waypoint attributes are then updated when the vehicle travels through them. For each current motor vehicle position, a search is made for the Waypoint spatially closest to the current motor vehicle position and having certain characteristics, such that if such a Waypoint is not found, then a new Waypoint is defined, or else, if such a Waypoint is found, then variable Waypoint attributes are updated. The so-defined Waypoints are then concatenated so as to form an ordered list of Waypoints belonging to the same recurrent route. The characteristic points of the routes, such as bends, roundabouts and traffic lights, are identified and optimal speed profiles and primary controls for the motor vehicle at the characteristic points are computed. Based on the computed optimal speed profiles and primary controls and by means of the automotive human-machine interface, the motor vehicle driver is then provided with motor vehicle driving recommendations for fuel saving along the routes.
