Abstract
A method for operating a powertrain, having at least one drive motor and at least one gearbox, of a motor vehicle which can be driven by the drive motor, via the gearbox, in which heat is transferred from the drive motor to the gearbox in a targeted manner, as a result of which the gearbox is heated in a targeted manner. The heat is transferred from the drive motor to the gearbox in a targeted manner on the basis of predictive data which include at least one future state of the motor vehicle.
Claims15
A method for operating a powertrain of a motor vehicle, the powertrain comprising:
- at least one drive motor and at least one gearbox, such that the motor vehicle is driven by the at least one drive motor via the at least one gearbox, the method comprising:
- transferring heat from the at least one drive motor to the at least one gearbox to heat the at least one gearbox in a targeted manner,
- wherein heat is transferred from the at least one drive motor to the at least one gearbox based on predictive data describing at least one future state of the motor vehicle, and
- wherein the predictive data comprises information describing an upcoming, temporary switch-off phase of the drive motor.
A motor vehicle comprising an electronic computing device and a powertrain with at least one drive motor and at least one gearbox, such that the motor vehicle is driven by the at least one drive motor via the at least one gearbox,
- wherein the electronic computing device is configured to control a transfer of heat from the at least one drive motor to the at least one gearbox in a targeted manner based on predictive data describing at least one future state of the motor vehicle, and
- wherein the predictive data comprises information describing an upcoming, temporary switch-off phase of the drive motor.
A method for operating a powertrain of a motor vehicle, the powertrain comprising:
- at least one drive motor and at least one gearbox, such that the motor vehicle is driven by the at least one drive motor via the at least one gearbox, the method comprising:
- transferring heat from the at least one drive motor to the at least one gearbox to heat the at least one gearbox in a targeted manner,
- wherein heat is transferred from the at least one drive motor to the at least one gearbox based on predictive data describing at least one future state of the motor vehicle, and
- wherein the predictive data comprises information describing a driving route of the motor vehicle.
