Abstract
A method for controlling a drivetrain for a road vehicle, in particular for a hybrid vehicle, is provided. The drivetrain includes at least an electric motor, an electric energy accumulator, and an active connection to at least one drivable axle. In the recuperation mode, thus, when an electric motor is operating as a generator for generating electric energy for charging an electric energy accumulator, the generated electric energy is transmitted at least partly to at least one electric heating resistor in order to convert the energy into heat.

A method for controlling a drivetrain of a hybrid vehicle, the drivetrain including at least an electric motor, an electric energy accumulator, and an active connection to at least one drivable axle, the method comprising the acts of:
- operating the electric motor as a generator for generating electric energy for charging the electric energy accumulator in a recuperation mode;
- and
- transmitting at least partly the generated electric energy to at least one electric heating resistor in order to convert the transmitted electric energy into heat.
A drivetrain for motor vehicle, comprising:
- an electric motor;
- an electric energy accumulator, wherein the drivetrain is actively coupled to at least one drivable axle;
- and
- a control unit and at least one electric heating resistor;
- and
- wherein the control unit is operatively configured to transmit generated electric energy to the at least one electric heating resistor in order to convert the transmitted electric energy into heat in a recuperation mode when the electric motor is operated as a generator for generating electric energy for use in charging the electric energy accumulator.
