发明名称 Method for determining a starting speed in a motor vehicle
摘要 A method for determining a startup gear in a motor vehicle for starting from standstill while maintaining a load limit of the clutch in a the drive train which comprises a drive engine built as an internal combustion engine, a friction clutch, and an automatic stepped transmission. To avoid overloading the clutch, the method determines a load-independent startup gear with which startup would occur under the present starting conditions without considering the current load state of the clutch and without complying with a load limit of the clutch. A load-specific startup gear is determined as the highest startup gear, with which during a startup under the present starting conditions, a predefined load limit of the clutch would be maintained with consideration given to the present load state of the clutch. The startup gear is the lowest of the load-independent startup gear and the at least one load-specific startup gear.
