Abstract: A computer system for controlling the operation of a drive of a motor vehicle includes a plurality of different predetermined components each including at least one functional unit. Such components include a first component representing the motor vehicle as a whole and second component representing the drive. A plurality of interfaces is interposed between these components, being operative for transmitting data between such components. At least one storage stores information concerning such components and interfaces. The functional units mentioned above and the vehicle as a whole are controlled by controlling the above-mentioned components inclusive of the first component. In performing the control, request signals and inquiry signals are generated and transmitted through the interfaces between the components. The operation of the drive is controlled in dependence on the data exchanged between the components through the interfaces.

Abstract: In a method for controlling the frequency of a traveling wave motor, in which an actual value proportional to the actual frequency of the excitation alternating voltage of the traveling wave motor (10) is obtained from the amplitude of an alternating voltage (sense voltage) tapped from the amplitude of a stator (11) of the traveling wave motor (10). The actual value is compared with the desired frequency of the proportional desired value and the excitation frequency is corrected with the deviation which was subjected to suitable control algorithm. In order to stop the traveling wave motor (10) at a stable operating point at maximal performance, the desired value is derived from the amplitude modulation of the sense voltage. This desired value is obtained in a superimposed control loop in which the sense voltage is demodulated, rectified and compared with a predetermined desired amplitude modulation value.

Abstract: The invention relates to an electric control arrangement for generating analog manipulated variables, having at least one basic controller circuit having a particular controller structure. The transfer function of the basic controller circuit, which is determined by the controller structure, is established with respect to magnitude by means of controller parameters and is supplied with an analog control-difference signal formed from desired value and actual value. A digital adjusting arrangement is provided for simple adaptation to the particular controlling task with the least possible complexity as to computation. The digital adjusting arrangement 34, on the basis of digital input quantities, selects at least one basic controller circuit 12 having a particular controller structure from several basic controller circuits 12 and switches this basic controller circuit 12 into the analog control loop and/or allows a variation of the controller parameters.

Abstract: Backwards counters (11,12) are preset with upper and lower limits of the angle through which screws are to be driven, the counters being loaded when a certain value of torque is reached, at which time counting down begins with each increment of rotary angle. When the operation is completed in the usual way after reaching a limit value of torque, the increasing interval between count pulses is detected by a delay circuit (7) and counting is stopped. A logic circuit (15) shows whether the screw connection is satisfactory or whether it is underdriven or overdriven.
