Method and regulating device for regulating a hybrid drive of a hybrid electric motor vehicle
First Claim
1. A method for regulating a hybrid drive of a hybrid electric motor vehicle which has an electric energy store (HV), having the steps:
- defining (S1) criteria for actuating an electric drive (EM1;
EM1, EM2) and/or an internal combustion engine (VM) of the hybrid electric motor vehicle on the basis of an adjustable driving mode, wherein a portion of a battery capacity of the electric energy store (HV) is reserved by means of a variable setting; and
regulating (S2) actuation of the electric drive (EM1;
EM1, EM2) and/or of the internal combustion engine (VM) of the hybrid electric motor vehicle by means of the defined criteria and by means of the variable setting; and
wherein a demand, determined by a sensor device, for an increase in traction of the hybrid electric motor vehicle is used as one of the criteria for the actuation of the electric drive (EM1;
EM1, EM2) and/or of the internal combustion engine (VM), andwherein availability of all-wheel drive is indicated on the basis of the reserved portion of the battery capacity of the electric energy store (HV).

Abstract
The invention relates to a method for regulating a hybrid drive of a hybrid electric motor vehicle which has an electric energy store (HV), said method having the following steps: determining (S1) criteria for engaging the electric drive (EM1; EM1, EM2) and/or the internal combustion engine (VM) using an adjustable drive mode, wherein a part of a battery capacity of the electric energy store (HV) is reserved using a variable setting; and regulating (S2) the engagement of the electric drive (EM1; EM1, EM2) and/or the internal combustion engine (VM) of the hybrid electric motor vehicle using the determined criteria and the variable setting.

9. A regulating device for regulating a hybrid drive of a hybrid electric motor vehicle which has an electric energy store (HV), wherein the regulating device is configured:
-
to define criteria for actuating an electric drive (EM1;
EM1, EM2) and/or an internal combustion engine (VM) of the hybrid electric motor vehicle on the basis of an adjustable driving mode, wherein a portion of a battery capacity of the electric energy store (HV) is reserved by means of a variable setting; andto regulate actuation of the electric drive (EM1;
EM1, EM2) and/or of the internal combustion engine (VM) of the hybrid electric motor vehicle by means of the defined criteria and by means of the variable setting; andwherein a demand, determined by a sensor device, for an increase in traction of the hybrid electric motor vehicle is used as one of the criteria for the actuation of the electric drive (EM1;
EM1, EM2) and/or of the internal combustion engine (VM)), andwherein availability of all-wheel drive is indicated on the basis of the reserved portion of the battery capacity of the electric energy store (HV).
