A drive train for a motor vehicle comprises an internal combustion engine which has a crankshaft and is designed to provide drive power for the motor vehicle. A clutch arrangement has an input member and at least one output member, the input member being connected to the crankshaft. A transmission arrangement implements a plurality of gear stages, the transmission arrangement having a transmission housing, at least one input shaft, and at least one output shaft. The output shaft is connectable to driven wheels of the motor vehicle. An electric machine is designed to provide drive power for the motor vehicle and is connected to a transmission shaft of the transmission arrangement. The transmission shaft has a shaft section which extends from the transmission housing and is connected to the electric machine via a traction drive mechanism.

Drive train for a motor vehicle

A drivetrain for a motor vehicle has a first electric machine provides drive power, wherein the first electric machine is connected to an electrical energy store. A differential can distribute drive power to two driven wheels or axles of the motor vehicle. A first transmission arrangement which connects the first electric machine to the differential. A second electric machine which is coupled to an internal combustion engine in order to charge the electrical energy store in a generator mode. A second transmission arrangement connects the internal combustion engine to the differential. The second transmission arrangement has a first gear stage and a second gear stage which can be alternately engaged, for the transmission of drive power from the internal combustion engine to the differential, by means of a clutch arrangement.

Drivetrain for a motor vehicle

Method for determining an adjustment parameter in a hydraulic actuator arrangement for a motor vehicle drivetrain. The actuator arrangement has a pump and a hydraulic cylinder. A pressure port of the pump is connected to a port of the hydraulic cylinder. The adjustment parameter is a function of the volume of the fluid that must be delivered by the pump in order to realize a predetermined operating point of the actuator arrangement. The operating point is defined by a value pair of an operating point rotational speed value of the pump and an operating point control value of the pump. The method has the steps: regulating the pump to the operating point rotational speed value such that the pump delivers a fluid volume flow rate corresponding to the operating point rotational speed value; and integrating the fluid volume flow rate over the time until a termination operating state of the actuator arrangement, in which the control value of the pump is less than or equal to the operating point control value.
