Problems solved by technology

There is currently a lack of information on the reachability of potentially driver-relevant travel goals for situations where there is no explicit goal input, where computation of all possible routes cannot reasonably be achieved due to insufficient computing power as well as visual representation. Representation of reachable road segments

Embodiment Construction

[0021]The basic idea of ​​the invention is that the driver of a vehicle with an electric motor drive, such as an electric vehicle, a hybrid or a fuel cell vehicle, can select a target memory in a specially designed target memory, in particular a so-called target memory for reachability estimation of a navigation device A plurality of driving targets are specified in , for which the reachability of the driving targets is automatically generated at regular intervals according to a trigger or a trigger signal at a determined time such as switching on and / or switching off of the electrical consumer, and Feedback to the driver on the current state of accessibility.

[0022] According to the invention, the driver can persistently store his typical, frequently driven destinations, such as home, workplace, school or kindergarten, shopping center, etc., in a special memory for the accessibility estimation, and / or Or they are marked in a common or other object memory, wherein these mark...

Abstract

The method involves performing range estimation of traveling distance of a vehicle based on a power consumption model of the vehicle, available amount of power and road database. The traveling distance is output in a form of accessibility of a destination of a driver of the vehicle. The range estimation is performed by a navigation system with the road database for exchanging information to a vehicle control unit based on present and defined destination when an explicit objective is not input to the navigation system. Independent claims are also included for the following: (1) a computer program for managing range of a vehicle (2) a device for managing a range of a vehicle.

Description

technical field [0001] The invention relates to a method for the reach management of a vehicle with an electric motor drive, based on an energy consumption model of the vehicle, the amount of energy available and a road database. Furthermore, the invention relates to a device for range management of a vehicle with an electric motor drive, which has a navigation system, a vehicle control device and a feedback device for the driver of the vehicle. Background technique [0002] For drivers of vehicles with electric motor drive, such as electric vehicles, hybrid or fuel cell vehicles, the main limitation lies in the significantly restricted reach relative to conventional vehicles, to which vehicles with their electric drive can return. reach range. If the (precisely) electric motor vehicle stops due to a lack of energy, there is no easy refueling possibility in this vehicle as in a motor vehicle with a conventional internal combustion engine. Therefore, the reachability manage...
