Title: METHOD FOR CONTROLLING A SHIFTING PROCESS
Abstract:
The invention relates to a method for controlling a shifting process depending on the shifting type - either an upshift in traction mode, a downshift in traction mode, a coasting upshift or a coasting downshift - of a hybrid drive comprising at least two drive elements and comprising at least one opening clutch and at least one closing clutch. The object of the invention is to improve the shifting process utilizing the new options which are provided by certain types of hybrid drives in addition to conventional hybrid drive modes: hybrid operating modes (gears) with an electrically adjustable, continuously variable transmission ratio (e-CVT operating mode). According to the invention, to achieve this a control element selects between a first shifting sequence or a second shifting sequence independently of the shifting type.
