摘要： A voltage-frequency converter having a chargeable and dischargeable memory, a comparator circuit and a subsequent multivibrator, wherein the charging and/or discharging signal for the memory is obtained from special signal sources. At constant charging and discharging signals, a linear voltage-frequency conversion is provided. In the case of variable charging or discharging voltages, non-linear signal conversions are possible. The multivibrator may be a digital monostable multivibrator, to effect precise, reproducible and quantifiable period durations in the output signal of the converter, and thus a very precise voltage-frequency conversion.

摘要： The resistance to supply voltage, e.g. battery, fluctuation of an input/output circuit for a control system, e.g. vehicular ignition/fuel injection system, is improved by placing a comparator K in each analog input line, and using a voltage divider UD to compensate the reference voltage U.sub.R applied to one of the comparator inputs. Processing speed is increased by using digital comparators 22-26, which test not only for threshold value equal to counter state, but also for threshold value greater than counter state, in the duty-cycle modification circuit. Chip count is reduced and integration is increased by using a single voltage divider to supply all the input comparators and by using a High-Speed Output (HSO) port on the central processing unit (CPU) to perform multiple output tasks.

To decrease the power requirements on the driver transistor, the driver transistor has its collector connected to the common junction (J) the voltage at line (13) of the driver and of the junction being arranged that the voltage at the junction (J) is less than the voltage at the base of the driver transistor when the switching transistor (5) is in fully saturated conductive condition, re-combination of charge carriers on the base of the switching transistor maintaining the switching transistor conductive until the charge carriers are exhausted, which causes a slight rise in voltage at the junction (J), but then causes increased conduction of the driver transistor due to the then overriding control from the driver transistor (11).

To insure rapid turn-off of the switching transistor (5), a control transistor (19) has its collector-emitter path connected across the base-emitter path of the switching transistor and, when rendered conductive, will cause the switching transistor to rapidly change to the blocked state.

摘要： To place the maximum combustion pressure, which occurs upon ignition, after the piston of an internal combustion engine (ICE) has passed upper dead-center (UDC) position upon starting, a predetermined time interval (Ti) is subtracted from the expected time the piston reaches UDC position, as determined by the time taken for a predetermined angular distance of the crankshaft to rotate; the time between the predetermined angular distances is extrapolated to determine the projected, or expected time of the UDC position. The predetermined time interval (Ti), which may be made dependent upon engine temperature, is then subtracted and the actual firing time computed, for example by counting-out in a counter the differential time interval determined by the subtraction. The timing intervals are preferably derived from a segmental marker system (20,21; A1,A2), in a counter (1), the extrapolation carried out in a multiplier (2) and the subtracting in a subtraction circuit (3). The system is preferably enabled upon closing of the starter switch (S) and may be disabled when a down-counter, determining the actual timing interval, has a negative count output.

摘要： The destination of commands provided by a microcomputer to an input-output unit over a data bus is provided without an address bus, while a control circuit in the input-output unit is connected with the microcomputer by connections for only three binary signals in one direction, "clear", chip-select and data strobe and one in the other, namely interrupt. The control circuit has a decoder connected to the data bus that sorts out the commands, feeding the outputs through a gate array that are enabled by the chip-select and data strobe signals for timing. Commands for switching, such as beginning and ending counts, and so on are one-byte commands directly transmitted to the appropriate circuits of the input-output. Read and write commands are two-byte commands sequenced by a sequencing and lockout circuit, the circuit selected in first byte being activated to read or write to or from the data bus in the second byte while the decoder is blocked. The direction of transmission of the data bus is controlled over a single connection from the control circuit in accordance with whether a write command is or is not present.

摘要： In the case of sensors having a characteristic for which the offset in the quiescent condition has a first temperature coefficient and the slope of the characteristic has a second temperature coefficient, while the quotient of the offset and slope coefficients is approximately constant, a point can be determined in which the characteristics for different temperatures (T) intercept. A temperature corrected measurement value can be determined, preferably with a microcomputer, from the sensor signal, the coordinates of the above-described intersection point, the sensor temperature and the temperature coefficient either of the offset or of the slope.

摘要： An input-output unit carries out some of the operations previously carried out in the microcomputer controlling the ignition, injection, etc. processes so that the number of bits in the microprocessor can be reduced. The input-output unit includes a counter which furnishes speed-dependent or angle-dependent signals. During a predetermined angle of rotation or while a particular speed-dependent value is counted and down, a frequency proportional to the quantity of air in the air inlet is counted, the resultant air number transferred to the microprocessor where it is modified. The modified air number can be counted down in the same counter which was used to count down the speed-dependent signals. The time required for counting down the modified air number determines the injection time and/or the closing time for an electronic switch in the primary circuit of the ignition coil. When the angle-dependent signal is used, a further counter counts down the air number several times, each time generating an interrupt signal. The latter count is in the microprocessor and when a predetermined number has been received, the microprocessor furnishes a terminate signal ending the controlled process.

摘要： A nonlinear characteristic curve of a frequency-voltage converter is approximated by summing the outputs of energized ones of a plurality of either voltage or current sources. The current sources are energized and de-energized in accordance with information contained in storage elements which may, for example, be parts of a shift register, or of an addressable storage. The breaks in the characteristic curve are achieved by changing the number of energized current sources or the current supplied by at least some of the sources at time intervals Ti=1/fi, where fi are the break frequencies and where time is measured starting with the leading edge of each pulse of the pulse frequence having the frequency f.sub.x which is to be converted to a voltage. Voltage-frequency converters can be created by connecting the frequency-voltage converter into the feedback path of a converter circuit receiving a voltage U.sub.x and furnishing the frequency f.sub.x in response thereto.

摘要： In a method for controlling the release of a passenger restraint system in a vehicle, an acceleration signal is measured and integrated with respect to time to obtain a velocity signal. A release threshold value for the velocity signal is determined. If the velocity signal then falls below the release threshold value, thus indicating a vehicle collision, the passenger restraint system is released. The release threshold value is controlled depending on the type of accident situation and upon the operating parameters of the vehicle to increase the release sensitivity of the passenger restraint system. For example, the release threshold value is adjusted based on the value of the velocity signal. If the velocity signal decreases in value, then the release threshold is lowered to a more sensitive value.
