摘要： A system for controlling a positioning unit in a motor vehicle includes various control units that influence the positioning unit coupled thereto. A drive slip control and an automatic transmission control both supply a control signal. Yet another control signal is dependent upon a driver request signal. For a period of time, the control signal from the automatic transmission control takes precedence over the other control signals.

摘要： The brake system having an electrically controllable brake apparatus of a trailer, the brake apparatus includes a control unit which is connected via electrical lines to an electrical energy source of a tractor. In braking, electrical currents are brought about of such a magnitude as to cause severe voltage drops in long lines that the functional safety of the brake apparatus may be threatened. The brake apparatus therefore has an electrical energy storage device disposed on the trailer, which can be charged by an energy source of the tractor and can be discharged upon triggering of the brake apparatus of the trailer. Voltage drops in the relatively short lines between the energy storage device and the control unit are therefore minimum. The lines between the electrical energy source of the tractor and the energy storage device of the trailer are charged by only low charging currents. The voltage drop is therefore low despite the long line length.

摘要： A knocking sensor (10) which provides output signals representative of combustion condition under knocking to thereby generate knocking signals which have mixed therewith noise or stray interference signals, and which also furnishes noise or stray interference signals under other than knocking combustion conditions, has its output connected to a plurality of parallel connected selective filters (2, 3). The filters have different pass band frequencies. One of the filters (3) is tuned to sense knocking frequencies, one or more other filters (2) being tuned to preferentially select noise or interference signals. A selection and discriminating circuit (10) having comparators (11) is provided connected to the filters to eliminate noise signals by comparing the signal level of the output received from the filters with a reference, which may be a dynamic reference, the outputs from the discriminators being processed in a logic circuit (15) to provide output signals (18) if (1) the filtered signal having the frequencies expected upon knocking exceeds a threshold level and (2) the filtered signal having the frequency band of the stray, or noise signals is below a threshold level and, preferably, a knocking signal persists for a time in excess of a time interval as determined by a timing circuit (16). Preferably, non-linear circuits such as logarithmic circuits (4, 5), are connected between the outputs from the filters (2, 3) and the comparators (11, 12) of the selection or recognition or discriminating circuit (10).

摘要： To provide a signal representative of angular crankshaft position from an ignition distributor, independently of change of ignition timing, the ignition distributor includes a further or additional rotating transducer system (8, 9, 10, 11), for example a rotating disk (8) positively coupled to the shaft (3) of the distributor. The disk (8) carries markers (10) which are picked up by an optic, magnetic (Hall generator) or inductive pick-up (9). To provide a reference marker output, for example a reference, e.g. TDC position of a reference piston, the rotating disk (8) can carry an additional reference marker (10a) picked up by a reference pick-up (9a) which can be similar to the other pick-ups used in the construction. The specific crankshaft position signals are especially suitable and desirable if the engine is coupled to an engine knock sensing and knock prevention system (KS).

摘要： To match the control adjustment speed of an internal combustion engine control system to operating speed thereof, a control loop is provided which includes an operating parameter sensor, a correlator comparing a sensed signal with an oscillating command signal, a controller responsive to a consequent error signal and which then controls operation of the engine; a speed transducer provides speed-dependent output signals which control (a) the frequency of oscillation of the oscillator and (b) the operating speed of the controller. If the controller is an integrating-type controller, then the time constant of the integrator thereof is changed, for example by varying a resistance value of an R/C circuit as a function of engine speed.
