Abstract
A method for controlling gear shifting in a motor vehicle which utilizes a drive assembly that includes an internal combustion engine having an output shaft, a multiple-gear transmission having a transmission input and a transmission output shaft that be selective coupled and uncoupled from one another, a main clutch assembly capable of causing the transmission input shaft and output shaft to be selectively coupled or uncoupled, an electrical machine capable of being selectively coupled to the transmission input shaft via an intermediate transmission, and a control unit for controlling the electrical machine and/or the intermediate transmission during gear shifting, as a function of a standard shift value provided to the transmission along with the operating parameters and the operating states of the components. According to the method, when the operator manipulates the gear shift lever for the main clutch and/or opens the same, a possible standard shift value and its associated transmission ratio (ip) are predicted, and the operating parameters and operating states of the electrical machine and of the control unit are controlled during the gear shift as a function of the possible standard shift value.
