发明名称 VERFAHREN ZUR REALISIERUNG DER SCHALTUNGEN EINES AUTOMATISCHEN SCHALTGETRIEBES EINES KRAFTFAHRZEUGES, INSBESONDERE EINER BREMSRÜCKSCHALTUNG
摘要 Method for implementing the gear changes of an automatic transmission of a vehicle, in particular of a dual clutch transmission, wherein for each possible sequential gear change, depending on the accelerator pedal position, an upshift threshold (HS) and/or a downshift threshold (RS) are each defined, specifically, the limiting value applicable to the respective up- or downshift being stored in a control device as a corresponding vehicle speed value, the changing vehicle speed and the changing accelerator pedal position during the vehicle's journey being measured and in a braking phase of the vehicle a downshift, in particular a braking downshift, being implemented. The driving comfort is increased by the fact that a braking process of the vehicle is first detected, namely an activation of the brake pedal is sensed, that a check takes place of whether the accelerator pedal is inactivated and that for the case where the brake pedal is activated and the accelerator pedal inactivated, the current vehicle speed (V3) is determined and compared with the respective lower limit value of the next lower upshift threshold (HS), namely with the zero-accelerator-pedal limit value (NF) of this upshift threshold (HS), and that then, if this zero-accelerator-pedal limit value (NF) or a specific difference value (DNF), calculated in relation to this zero accelerator-pedal limit value (NF), has not been reached, then the lower gear in the transmission defined by the thereby unattained upshift threshold (HS) is engaged.
