Embodiment Construction

[0036] figure 1 A symbolic flow diagram is shown indicating the steps and the order in which they occur in the methods described herein.

[0037] First, in step 10 , traffic and / or road conditions ahead of the vehicle are detected, in particular automatically detected. For example, detection by distance sensors or by other vehicle-side units with which information about the traffic or road conditions ahead may be gathered.

[0038] In a following step 20 , based on the data detected in step 10 , an upcoming expected increase in the power request of the hybrid drive is determined. In particular, this determination is an evaluation, wherein, as already mentioned, this expected increase serves as an evaluation value.

[0039] In step 30, the extraction rate of electrical energy extraction from the hybrid drive is increased. In this case, for example, a battery which is only used to supply the electric traction motor of the hybrid drive is used as the electrical energy source. ...

Abstract

The invention relates to a method for controlling a hybrid drive of a vehicle. First a traffic and / or street situation ahead of the vehicle is detected (10). Based on the detected situation, an upcoming, increase of a power requirement to be expected from the hybrid drive is determined (20) and a withdrawal rate of an electrical energy source of the hybrid drive is increased (30). This increase occurs before the power requirement is realized. Finally, the power requirement is realized according to the increase (40) of the withdrawal rate , in particular in conformity with a power requirement, as this is entered via an interface, for example an accelerator pedal.

Description

Background technique [0001] Hybrid drives with an electric drive component and a drive component based on an internal combustion engine are known. It is also known to operate both drive parts simultaneously, so that both drive parts act on the drive device. This results in a higher overall drive power. [0002] In publication DE 10 2011 085 462 A1 an electric drive component called "boost" is described which can activate a hybrid drive, wherein the type of drive is positively determined on the basis of a route schedule. Depending on the route ahead, the electric drive components are activated at a specified upcoming point on the route. In this document it is assumed that the electric drive components and the corresponding energy sources supplying them are fully available at times which have been precalculated. This can be done, for example, by a corresponding design of the response speed of the components, wherein, on the one hand, the detailed prior art does not consider t...
