Problems solved by technology

Furthermore, the current state of the hybrid vehicle is not considered either in determining the optimal route or in goal guidance
Due to the characteristics of the drive train, especially in the direction of consumption, which can change dynamically, especially since the efficient route cannot guarantee that the solution always found is ideal
In particular, the pre-planning of the possibility of charging the battery in hybrid vehicles is mostly poor or not possible at all in the determination of efficient routes

Embodiment Construction

[0028] The method according to the invention involves the determination and updating of an efficient route for maximum utilization of the electric machine, which is in particular also dynamically adjustable from the current position of the hybrid vehicle to the destination. Here, the determination and dynamic adjustment of the efficient route is based on efficiency information transmitted from the vehicle's drive controller (which controls components of the hybrid drive train with electric motor and internal combustion engine) to the navigation controller of the navigation system, the efficiency The information depends, in particular, on the real-time operating state of the hybrid drive train and, if available, on the real-time operating forecast. First refer to figure 1 Specific descriptions of efficient route assumptions in general, figure 1 A very simplified map segment 1 is shown, which shows the possibility of reaching a destination 3 from the vehicle's current position ...

Abstract

The invention relates to a method for operating a navigation system (25) of a hybrid motor vehicle (16) comprising a combustion engine (19) and an electric motor (18) which is powered by the associated battery (21), an efficient route (7, 12) enabling the electric motor (18) to be used to its maximum capacity is determined by the navigation system (25), said efficient route (7, 12) being determined by providing at least one dynamic of a drive control device (23) of the vehicle (16) from which the current operating state and / or a current operating prediction dependent on the efficiency information is taken into account.

Description

technical field [0001] The invention relates to a method for operating a navigation system of a hybrid vehicle having an internal combustion engine and an electric machine which is powered by an associated battery. Furthermore, the present invention also relates to a hybrid vehicle. Background technique [0002] Hybrid vehicles are known in the prior art and use two different drive motors which implement different drive concepts. In this case, as is known from conventional vehicles, an internal combustion engine is generally used on the one hand, which generates the drive power by burning engine fuel from a fuel tank. In addition to the internal combustion engine, an electric machine is also provided in the hybrid drive train, which can usually also be operated as a generator and is powered by a battery, usually a high-voltage battery. The battery can also be charged by the generator operation of the electric machine, for example by regeneration and / or by saving a portion ...
