The device has an machine that can be operated as an electric motor to drive the vehicle through a drive train, at least one clutch between the electrical machine and an output for driving vehicle wheels. A controller can operate the clutch(es) to transfer torque with slip while preventing thermal overload of the clutch and motor if increased temperatures or heat losses occur in the machine at very low speed simultaneously with high torque. The device has at least one electrical machine (EM2) that can be operated as an electric motor to drive the motor vehicle through a drive train, a clutch arrangement with at least one clutch (14) between the electrical machine and an output for driving the vehicle's driven wheels. A controller (8) can operate the clutch(es) to transfer torque with slip while preventing thermal overload of the clutch and motor when increased temperatures or heat losses occur in the electrical machine at very low speed simultaneously with high torque. |
