Claims10
A method for operating a hybrid electric vehicle, comprising:
- a drivetrain with an internal combustion engine and at least one electric motor, wherein a start of the internal combustion engine is suppressed when the vehicle is in an electric driving mode and a driving distance to a destination point of the vehicle is less than a predetermined route distance,
- wherein the internal combustion engine is set up to no longer be started up before reaching the travel destination when the driving distance to the travel destination is less than a predetermined value.
A drive system for a hybrid electric vehicle, comprising:
- an internal combustion engine and at least one electric motor for driving the vehicle;
- a control unit, which is set up to regulate the power output of the internal combustion engine and of the at least one electric motor, which includes starting up and turning off the internal combustion engine, wherein the control unit is set up to receive and process data of a navigation instrument,
- wherein a control instrument is set up to no longer start up the internal combustion engine before reaching the travel destination when the driving distance to the travel destination is less than a predetermined value.
