Abstract: In a method for operating an internal combustion engine, a steady-state maximum output torque and a dynamic maximum torque are ascertained. The ascertained steady-state maximum output torque is changed to a resulting steady-state maximum torque by adapting the maximum output torque in such a way that it is equal to or greater than the ascertained dynamic maximum torque.
Abstract: A method for operating a hybrid drive device of a motor vehicle that has at least two different drive aggregates, in particular an electric motor and an internal combustion engine, and having a clutch, the drive aggregates being capable of being operatively connected using the clutch. It is provided that, in a diagnostic, and/or adaptation operating mode; the clutch is operated with a slippage. In addition, the present system relates to a hybrid drive device, a control device for a hybrid drive device, and a motor vehicle aggregate that has both the control device and the hybrid drive device.
Abstract: A plastic spring having a corrugated tubular body with connection surfaces at its ends for transmitting force between two structural component parts which are movable relative to one another. A connection surface of the plastic spring is constructed as a tubular body which engages in a cup element of one of the supporting structural component parts. The cup element can be filled with a displacement mass, and the tubular body accordingly carries out a displacing movement within the cup element for axially adjusting the preloading of the plastic spring.

Plastic supplemental volume fractions determine the finished body contour.

Abstract: In a method for determining a gradient-limited setpoint torque from a requested setpoint drive torque and a controller setpoint torque of a closed-loop speed control, the gradient of an unlimited cumulative setpoint torque, which is a function of the requested setpoint drive torque and the controller setpoint torque of the closed-loop speed control, is limited in a region of the zero crossing of the gradient-limited setpoint torque by a rate-of-change limitation to a maximally permitted or a minimally permitted value. The maximally permitted or the minimally permitted value of the rate-of-change limitation is a function of the controller setpoint torque of the closed-loop speed control.

Abstract: A method for operating a hybrid drive for a vehicle including at least one internal combustion engine and at least one electric motor, the internal combustion engine and the electric motor being operable in a hybrid mode, which enables a temporary power boost by supplementing the internal combustion engine output with electric motor output. The temporary power boost is allowed only until reaching a limit velocity (VG), which depends on the maximum velocity (VSM, VSM?) in internal combustion engine mode, which depends on the particular driving resistance.
