Method and device for operating a generator
A method for operating a generator for an internal combustion engine of a vehicle having a starting operating mode and a start-stop operating mode, a torque of the generator being delimited in the starting operating mode, including: detecting an operating mode of the vehicle, and deactivating a delimitation of the torque of the generator if the detected operating mode corresponds to the start-stop operating mode.
1. A method for operating a generator for an internal combustion engine of a vehicle having a starting operating mode and a start-stop operating mode, wherein a torque of the generator is limited in the starting operating mode, the method comprising:
detecting an operating mode of the vehicle; and
preventing the limitation of the torque of the generator if the detected operating mode corresponds to the start-stop operating mode.
2. The method of claim 1 , wherein the detecting includes monitoring a communication between an internal combustion engine control unit and a generator controller.
3. The method of claim 2 , wherein the preventing of the limitation of the torque of the generator is a function of a detected pulse-width-modulated signal, which is transmitted from the internal combustion engine control unit to the generator controller, for controlling an operating mode of the generator controller.
4. The method of claim 1 , wherein the detecting of the operating mode of the vehicle includes detecting an internal combustion engine operating mode.
5. The method of claim 1 , wherein the preventing of the limitation of the torque of the generator includes preventing a load-response function of the internal combustion engine control unit.
6. The method of claim 1 , wherein the preventing of the limitation of the torque of the generator includes the use of an alpha jump for the starting operation.
7. The method of claim 1 , wherein the preventing of the limitation of the torque of the generator includes activating a stabilizing device of the vehicle electrical system.
8. The method of claim 1 , wherein the detecting of the operating mode of the vehicle includes detecting an operating mode of the generator controller.
9. The method of claim 1 , wherein the limitation of the torque of the generator is additionally prevented as a function of a detected temperature of the generator.
10. A device for operating a generator for an internal combustion engine of a vehicle having a starting operating mode and a start-stop operating mode, wherein a torque of the generator is limited in the starting operating mode, comprising:
a detector to detect an operating mode of the vehicle; and
a prevention device to prevent the limitation of the torque of the generator if the detected operating mode corresponds to the start-stop operating mode.
11. The device of claim 10 , wherein the prevention device is integrated into a generator controller.
12. The device of claim 10 , wherein the detector is configured to monitor a communication between an internal combustion engine control unit and the generator controller.
13. The device of claim 10 , wherein the detector has a temperature sensor for detecting a generator temperature, and the prevention device is also formed to prevent the limitation of the torque of the generator as a function of the detected temperature.
