Method and device for driving a motor vehicle with hybrid drive

摘要

A method for driving a motor vehicle includes selecting a drive mode. The motor vehicle has a hybrid drive including an internal combustion engine and an electric machine for providing a drive torque (t) for driving the motor vehicle. The motor vehicle is drivable by a torque of the internal combustion engine, by virtue of the internal combustion engine being started, or by a torque of the electric machine. The method includes detecting an amount of running activity (tB) of the internal combustion engine. The drive mode is selected based on the detected amount of running activity (tB).

1. A method for driving a motor vehicle having a hybrid drive that includes an internal combustion engine and an electric machine for providing a drive torque (t) for driving the motor vehicle, the motor vehicle being drivable by a torque of the internal combustion engine, by virtue of the internal combustion engine being started, or by a torque of the electric machine, the method comprising:
detecting an amount of running activity (tB) of the internal combustion engine using a running activity detection unit, the amount of running activity (tB) being one of a total distance travelled by the motor vehicle or a total operating duration of the internal combustion engine; determining a temperature of the internal combustion engine using a temperature sensor; selecting, using a control unit, a drive mode based on the detected amount of running activity (tB) and the determined temperature of the internal combustion engine; and driving the motor vehicle by at least one of the internal combustion engine or the electric machine based on the selected drive mode.
