Increased automatic gear box spontaneity |
摘要 |
The invention relates to a method for increasing the spontaneity of automatic gear boxes with overlapping gear shifts. The overlapping gear shifts consist of three phases. Upshifting from a first gear ratio to a second gear ratio is aborted and downshifting to a first gear ratio occurs if an abort criterion is detected. The abort criterion is validated if a request for downshifting is made by the driver and detected before the third overlapping shift phase begins. |
