发明名称 SHIFT-CONTROL METHOD FOR A VEHICULAR AUTOMATIC TRANSMISSION
摘要 A method for controlling a gear shift in an automatic transmission of a motor vehicle that is carried out as a deceleration shift of at least one engaging shifting element, without use of a mechanical free-wheeling condition. To increase the ride comfort, it is proposed that during the shifting sequence of the deceleration shift, a free-wheeling condition is simulated by a slip operation or by an opening of a second shift element of the automatic transmission, that is located in the power flow path, preferably using a start-up shift element of the automatic transmission.
