Abstract
A method for operating a motor vehicle having a hybrid drive, and to a motor vehicle configured for carrying out the method. In a hybrid operating mode of the motor vehicle, a proportion of a purely electric driving operation is maximized by controlling the automatic transmission so a resulting rotational speed is not lower than a preset minimum value.
Claims19
A method for operating a motor vehicle, comprising:
- providing a drive train with an internal combustion engine, an electric motor, and an automatic transmission, the electric motor arranged between the internal combustion engine and the transmission;
- and
- maximizing, in a hybrid operating mode of the motor vehicle, a proportion of a purely electric driving operation by controlling the automatic transmission so a resulting rotational speed is not lower than a preset minimum value, which is within a range of 0 to 100 rpm below a breakpoint speed of the electric motor.
A motor vehicle, comprising:
- a drive train with an internal combustion engine, an electric motor, and an automatic transmission, the electric motor arranged between the internal combustion engine and the transmission;
- and
- a device to control the automatic transmission during a purely electric driving operation of the motor vehicle so that a resulting rotational speed is not lower than a preset minimum value within the range of 0 to 100 rpm below a breakpoint speed of the electric motor.
