Method for controlling an automatic gearbox |
摘要 |
When a cold start condition exists, an electronic gear control (4) calculates for an automatic transmission (3) driven by an internal combustion engine (1) the energy throughput of the internal combustion engine (1). The energy throughput is added up and compared with a limit value. The shift points of the automatic transmission (3) are pushed up to higher values as long as the calculated value remains less than the limit value.
