Method and apparatus for providing a quantity of decision points from a backend server to a vehicle during a driving process

A method for obtaining a quantity of decision points from a backend server to a vehicle during a driving process using the vehicle, the method comprising:

• sending a first request message to request a first quantity of decision points from the vehicle to the backend server;
• receiving from the backend server the first quantity of decision points using the vehicle, responsive to the first request message;
• determining a traversal of a decision point of the first quantity of decision points using the vehicle;
• and
• if a decision point from the first quantity of decision points has been traversed:
• sending a second request message to request a second quantity of decision points from the vehicle to the backend server;
• and
• receiving from the backend server the second quantity of decision points using the vehicle, responsive to the second request message
• sending from the vehicle to the backend server a third request message to request a third quantity of decision points, if a time for receiving a response to a latest request exceeds a specified time period.

A method for providing a quantity of decision points from a backend server to a vehicle during a driving process using the vehicle, the method comprising:

• receiving a first request message to request a first quantity of decision points from the vehicle at the backend server;
• determining the first quantity of decision points using the backend server;
• reducing a number of decision points of the first quantity of decision points by the backend server;
• sending the reduced first quantity of decision points as the first quantity of decision points in response to the first request message from the backend server to the vehicle;
• and
• wherein the reduction of the number of decision points of the first quantity of decision points comprises:
• filtering the first quantity of decision points depending on an importance of the decision points;
• or
• merging decision points lying within a specified radius or multiple specified radii of circles around a position of the decision point;
• or
• determining a specified, maximum number of decision points for the first quantity of decision points, depending on the importance of the decision point.
