Method and control unit for controlling a hybrid drive of a vehicle
First Claim
1. A method for controlling a hybrid drive of a vehicle, the hybrid drive having an electric drive and a fuel drive, the vehicle having a control unit, and the method comprising:
- providing a database which has assignments between route information and first and second route criteria, the route information representing routes which may be traveled by the vehicle, the first route criterion representing a preferred use of the electric drive on the assigned route, and the second route criterion representing a preferred use of the fuel drive on the assigned route;
receiving a current route information via an interface, the current route information representing a route which one of is being traveled or is to be traveled by the vehicle;
determining by the control unit a current route criterion assigned to the current route information based on the database;
providing a piece of control information by the control unit for using the electric drive if the current route criterion is the first route criterion, and for using the fuel drive if the current route criterion is the second route criterion;
receiving updating information via an updating interface, the updating information having an updated route criterion at least for one piece of route information in the database, wherein the updated route criterion is either the first route criterion or the second route criterion; and
updating the database based on the updating information.

Abstract
A method for controlling a hybrid drive of a vehicle, the hybrid drive having an electric drive and a fuel drive. A database which has assignments between route information and first and second route criteria is provided. The route information represents routes which may be traveled by the vehicle. The first route criterion represents a preferred use of the electric drive on the particular assigned route, and the second route criterion represents a preferred use of the fuel drive on the particular assigned route. Current route information which represents a route traveled by the vehicle is received, and a current route criterion assigned to the current route information is provided from the database, and control information is also provided for using the electric drive if the current route criterion is the first route criterion or for using the fuel drive if the current route criterion is the second route criterion.
