Abstract: A method for operating a drive device is disclosed. The drive device has manual transmission has an intermediate shaft operatively connected with an output shaft, and a countershaft. In a first acceleration operating mode of the drive device a first electric motor and a second electric motor of the drive device are operatively connected with the intermediate shaft via the countershaft, and in a second acceleration operating mode the first electric motor is directly connected with the intermediate shaft and the second electric motor is operatively connected with the intermediate shaft via the countershaft. When switching between the first acceleration operating mode and the second acceleration operating mode the operative connection between the first electric motor and the intermediate shaft is interrupted for a defined switching time period. During the switching time period the second electric motor is operated with an overload torque.

Abstract: A method for operating a motor vehicle, including at least one electric motor connected to at least one rechargeable energy storage unit that stores electrical power, wherein the charging operation of the energy storage unit is carried out in such a way that a charging state limit that lies below the maximum charging state of the energy storage unit is not exceeded, wherein upon activation of at least one vehicle starting system, which is designed to automatically carry out a maximum acceleration of the motor vehicle from the standing position, the charging operation of the energy storage unit is carried out before the acceleration of the motor vehicle in such a way that the energy storage unit is charged up to a further charging state limit that lies above the first charging state limit and/or at least one further rechargeable energy storage unit is connected in series

Abstract: In a method for cooling a component of a motor vehicle, which component is coupled thermally to a cooling volume filled with a liquid coolant, at least one cooling parameter is measured by a control device and, in dependence on the cooling parameter, the component is either cooled in a first cooling mode, in which the cooling volume is connected via a first and second coupling device to a cooling circuit which includes at least one circulating device by means of which the coolant is circulated, or is cooled in a second cooling mode, in which the cooling volume is separated from the cooling circuit by the first and second coupling device, wherein the component is cooled by evaporation of coolant in the cooling volume.
