Abstract
The disclosure relates to methods for operating an automatic start/stop system in a motor vehicle having an internal combustion engine and an automatic clutch, wherein the automatic start/stop system automatically opens the clutch as a function of propulsion requests, wherein the automatic opening of the clutch is prohibited in certain driving situations such as detected hazardous situations.
Claims6
A method for operating a start/stop system in a vehicle having an engine and automatic clutch comprising:
- issuing, when the start/stop system is operating, a prohibit open clutch command in response to (i) the automatic clutch being closed and (ii) a change in brake line pressure over time or a change in brake pedal stroke over time being greater than a threshold value such that the automatic clutch remains closed and automatic stopping of the engine is precluded for a predetermined period of time.
A method for operating a start/stop system in a vehicle having an engine and automatic clutch comprising:
- issuing, when the start/stop system is operating, a prohibit open clutch command in response to the automatic clutch being closed and a change in steering wheel angle over time being greater than a threshold value such that the automatic clutch remains closed and automatic stopping of the engine is precluded for a predetermined period of time.
A method for operating a start/stop system in a vehicle having an engine, drivetrain, and automatic clutch arranged to couple the engine and drivetrain when closed, the method comprising:
- issuing, when the start/stop system is operating, a prohibit close clutch command in response to the automatic clutch being open and a change in steering wheel angle over time being greater than a threshold value such that the automatic clutch remains open and the engine remains decoupled from the drivetrain for a predetermined period of time.
