Embodiment Construction

[0065] figure 1 A motor vehicle, indicated generally at 10, is schematically shown. The motor vehicle 10 has a drive train 12 which in this case includes an electric machine 14 for providing drive power. Driveline 12 is used to drive driven wheels 16R, 16L of motor vehicle 10 . The powertrain 12 may be a purely electric powertrain or may be in the form of a hybrid powertrain including an internal combustion engine.

[0066] The electric machine 14 provides a drive torque t for driving the driven wheels 16R, 16L at the output shaft 18, wherein the output shaft 18 is connected by means of a clutch 20 or can be connected to a gear mechanism unit 22 in order to transfer the drive torque t is transmitted to the variable lock-up differential gear mechanism 24 . The variable lock-up differential gear mechanism 24 is used to transmit the driving torque t to the driven wheels 16R, 16L according to the situation and to transmit the driving torque t individually accordingly. AR , t ...

Abstract

The invention relates to a method for controlling a locking type differential gear mechanism (24) of a transmission train (12) of a motor vehicle (10). In order to drive the motor vehicle (10), a drive torque (t) is provided by an electric machine (14); and, in order to drive drive vehicle wheels (16R, 16L), the drive torque is transmitted to the locking type differential gear mechanism (24), wherein a reaction torque of the electric machine (14) is used to control the locking type differential gear mechanism (24) on the basis of the reaction torque.

Description

technical field [0001] The invention relates to a method for controlling a locking differential gear mechanism of a drive train of a motor vehicle, wherein a driving torque is provided by an electric machine for the purpose of driving the motor vehicle and for driving the motor vehicle The purpose of the plurality of drive wheels is to transmit drive torque to the locking differential gear mechanism. [0002] The invention also relates to a device for controlling a locking differential gear mechanism of a drive train of a motor vehicle, the device comprising a torque detection unit associated with an electric machine in order to determine or detect the torque of the electric machine, the An electric machine is connected to the locking differential gear mechanism for the purpose of transmitting driving power, and the device includes a controller connected to the locking differential gear mechanism to set the locking differential gear mechanism. The locking value of the differe...
