The invention relates to a method () for the active damping control for an electric vehicle or hybrid vehicle having an electric motor drive element (), comprising the steps of receiving a current target torque value (tq) of the electric motor drive element (), determining a current rotational angle value (&#x3c6;) of the electric motor drive element (), and determining a current damping torque value (tq), characterized in that the current damping torque value (tq) is determined using a reduced drive train model (rTSM).

Active damping control for an electric vehicle or hybrid vehicle

The invention relates to a method for permitting adaptation of the clutch torque of a proportional clutch in parallel hybrid vehicles, wherein given certain peripheral conditions the method is triggered automatically by a control device and the internal combustion engine rotates but is not ignited (phantom start).

Adaptation of the clutch torque of a clutch of a parallel-hybrid drive train of a vehicle

In a method for leak testing in an automated electrohydraulic clutch system in a motor vehicle, in which an electromechanical actuator controls the clutch travel of a clutch via a hydraulic piping system, in order that a defective system is detected reliably and rapidly, the leak in the clutch system is detected using a pressure measurement in the electromechanical actuator and compared to a characteristic clutch curve.

Method and device for leak testing in an automated electrohydraulic clutch system in a motor vehicle

A method and a device for operating a vehicle having a hybrid drive are described, in which a first drive unit and a second drive unit contribute jointly or individually to the drive of the vehicle, the first drive unit driving the second drive unit in the manner of a generator for charging an energy storage device, the first drive unit and the second drive unit being separable by a drive train element transferring a torque of the first drive unit. In a method in which it is ensured that the vehicle may continue to drive safely even in the event of a defect in a drive train element between the first drive unit and the second drive unit, the torque portion used for charging the energy storage device is reduced to a minimum torque, while the torque excess, which is reduced in the event of a defect in the drive train element but still exceeds the minimum torque, is utilized to propel the vehicle.

Method and device for operating a vehicle having a hybrid drive

A method and a system are described for controlling an electrical machine in a drivetrain of a motor vehicle, the electrical machine being used as a drive unit for the motor vehicle. A pilot control unit determines a pilot control torque as a function of a predefined target torque of the electrical machine, the pilot control unit having a transfer function that corresponds to an oscillation component of a transfer function, ascertained in model-supported fashion for the overall drivetrain, that describes a dependence of a rotation speed of the electrical machine on a torque with which the electrical machine is operated. A control unit for the electrical machine determines a corrected target torque for the electrical machine by superimposing the pilot control torque on the predefined target torque and controlling the electrical machine as a function of the corrected target torque.
