A method and a device for controlling a drive unit are provided, which allow for a reproducible load reversal damping. For this purpose, a setpoint value for an output variable of the drive unit is limited so that an overrun fuel cutoff of the drive unit is prevented. A limiting value for the setpoint value for the output variable is formed as a function of a loss value of the drive unit.

A method and an arrangement control the drive unit of a vehicle. In this method and arrangement, an rpm limiting to a reference rpm takes place when the demand of the driver is withdrawn. The reference rpm is determined at the start of the withdrawal of the driver command.

A method and a device for controlling an output variable of a drive unit in the starting phase is described. A controller is provided, regulating the actual value of at least one output variable to a setpoint variable of this output variable which is specified as a function of time. When at least one condition marking entry into the starting phase exists, the setpoint value of the output variable is initialized with the actual value of the output variable.

A tabulator device for typewriters, particularly for teleprinters or data-printers in which tabulation marks are set, cancelled and recalled, in which a store having electronically operable storage elements are operative to effect storage of the desired tabulation marks, register means being provided for addressing the respective storage elements of such store, with the setting i.e. insertion, or cancelling i.e. removal of a mark from the store being effected by means of a write-in control unit operatively connected thereto and tabulation marks being read out of the store by the aid of a read-out control unit operatively connected thereto. The store is in the form of a semi-conductor store constructed from MNOS (metal-nitride-oxide-substrate) transistors and thus does not change its contents following disconnection of the operating voltage. Where the matrix is in the form of a row and column matrix, two registers may be employed which may be in the form of shift registers provided with feedback.

During a start, particularly during a cold start, of an internal combustion engine without additional auxiliary drive, a precisely metered fuel mass is introduced into a combustion chamber. In the case of an internal combustion engine having direct fuel injection, a rail pressure prevailing in a high-pressure accumulator is frequently only insufficiently built up during a start, which has an unfavorable effect on the mixture formation. To improve the start performance of the internal combustion engine, the injection pressure available in the high-pressure accumulator is monitored during the start, and fuel from the high-pressure accumulator is first injected into the at least one combustion chamber when the injection pressure has reached or exceeded a specifiable threshold value. This ensures that the rail pressure is high enough, in order to inject a sufficient quantity of fuel into the combustion chamber so that an ignitable air/fuel mixture is formed.

A circuit arrangement is disclosed for storing messages formed of teletypewriter characters in a teletypewriter system. The teletypewriter system has a reception control which can be supplied with teletypewriter characters from a teletypewriter line or an input device. The teletypewriter system also has a transmission control which can emit teletypewriter characters to a teletypewriter line or the reception control. A memory unit is supplied with teletypewriter characters from received and written-in messages via the reception control. A memory in the memory unit has electronically triggerable memory elements arranged in matrix-like fashion. The teletypewriter characters may be stored in the memory and are not lost when an operational voltage to the memory is switched off. The memory emits teletypewriter characters of a message which is to be transmitted to the transmission control.

The invention relates to a strain relief/bending protection apparatus for a cable, in particular a high speed cable, connected to a plug connector, comprising a base section which can be fastened to a housing of the plug connector and a sleeve section projecting from the base section for surrounding the cable in a region disposed outside the housing, wherein the sleeve section continuously has a round cross-section and the cross-sectional area of the sleeve section reduces as the spacing from the base section increases.
摘要:
Proposed is a method for adjusting an adaptive characteristics map of an adaptive engine-knock control system and a method for adaptively controlling engine knock, the adaptive characteristics map being defined by at least one operating parameter, the adaptive characteristics map for each operating-parameter range being made up of a precontrol component that characterizes the ambient conditions, and a residual component that results from the engine-knock control, the value of the adaptive characteristics map for each operating-parameter range being given by the sum of the precontrol component corresponding to the specific operating-parameter range, and the residual component corresponding to the specific operating-parameter range. In this context, the adjustment of the adaptive characteristics map is carried out by initially determining if ambient conditions have changed, and by subsequently ascertaining a new precontrol component as a function of the changed ambient conditions for each operating-parameter range, if the ambient conditions have changed, or by holding the precontrol component constant for each operating-parameter range, if the ambient conditions have not changed.
摘要:
A code generator for teleprinters or data printers which, for the recognition of the subscriber, emits a sequence of character signals assigned to the subscriber. A memory is provided which is constructed from electronically operable storage elements in which the character signals are stored and are not altered after the disconnection of the operating voltage. Registers are provided which contain the addresses of the particular operated storage elements and a read-out control unit is provided by means of which the character signals are read out from the storage elements.
