Controlling automatic gearbox involves initiating shift event if derived period less than defined applicable period, adapting applicable period depending on assessment of shift performed

摘要

The method involves determining the gradient of an input revolution rate during a shift, deriving the interval from a current operating point to a synchronous revolution rate, initiating at least one shift event if the period is less than a defined applicable period and adapting the applicable period depending on an assessment of the shift performed so that the desired ratio is achieved for a new shift with the synchronous revolution rate.
