Abstract
A method for controlling an automatic hybrid transmission of the motor vehicle is disclosed, wherein the hybrid transmission has at least two engageable gear stages with different transmission ratios, and wherein at least one variable driving range, i.e., at least one specific dynamic powertrain path is engageable such that the entire output torque of the output shaft is formed from the respective drive torque of the internal combustion machine and the electric machine. Losses of comfort to the driver and/or the danger of component damage and the associated costs are reduced by checking during a stopping process, and/or during a deceleration process of the motor vehicle and a downshifting that is requested in this context whether there is a specific operating situation, and the variable driving range is engaged in the event that a specific operating situation exists.
