Embodiment Construction

[0035] figure 1 A drive train 1 of a hybrid vehicle is shown in which the torque of an electric machine 2 as a first drive unit is added to the torque of an internal combustion engine 3 as a second drive unit. The electric machine 2 acts here directly or via the planetary gear train 4 on the transmission input shaft 5 . One of the two couplings is selected by closing one of the two positive clutches 6 , 7 . When the clutch 6 is engaged, the electric machine 2 acts directly on the transmission input shaft 5 . When the clutch 7 is engaged, the electric machine 2 acts on the sun gear 8 of the planetary gear train 4 and thus on the transmission input shaft 5 with a transmission ratio ≠1. The web of the planetary gear train 4 is connected to the transmission input shaft 5 and the ring gear of the planetary gear train 4 is connected to the transmission housing. In addition, a starter clutch 9 is present. Several transmission gear stages 10 can be connected to drive wheels 11 of ...

Abstract

A method for changing a drive unit's mechanical coupling to a motor vehicle power train which has at least two drive units, wherein at least one first drive unit (2) of the two drive units (2, 3) is coupled via various mechanical couplings, especially mechanical transmission ratios (iEIM), during the travel of the motor vehicle, a power or torque influence of the two drive units (2, 3) occurring if there is a change of the mechanical coupling. To ensure a change of the mechanical coupling without the vehicle occupants perceiving it, the change of the mechanical coupling of the first drive unit (2) of the two drive units occurs (2, 3) in at least two operating modes, a first operating mode causing a slower operating point change with respect to time of the two drive units(2, 3), while a more rapid operating point change as to time of the two drive units(2, 3) is provided in a second operating mode.

Description

technical field [0001] The invention relates to a method for changing the mechanical coupling of a drive unit of a motor vehicle, which is equipped with at least two drive units, wherein at least the first of the two drive units The drive units are coupled via different mechanical couplings during the driving of the motor vehicle, wherein the power or torque of the two drive units is influenced when the mechanical coupling is changed, and the invention relates to a motor vehicle control unit and a device for executing The transmission controller of the method. Background technique [0002] People are familiar with motor vehicles, especially hybrid, electric or hydraulic vehicles, which have at least two drive units, wherein at least the first of the two drive units can be coupled to the power by different mechanical couplings. on the system. The power or torque of the first and further drive units is influenced when such a mechanical coupling is changed, for example, when ...
