Title: Electronic control system for an automatic power transmission
IPC: F16H61/08
Filed: 1971-10-20
Abstract: 1344150 Change-speed control NISSAN MOTOR CO Ltd 20 Oct 1971 [21 Dec 1970] 48688/71 Heading F2D In a planetary automatic transmission having fluid-pressure engaged clutches and brakes selecting, e.g. three forward ratios, of which the first is a one-way drive, a speed-varied neutral interval is provided electronically during a downshift from the highest to the next highest ratio, (3-2), to allow engine synchronizing time, by temporarily engaging the one-way first ratio. The gear, not shown, is controlled by two solenoid valves, the solenoids 13, 14 of which are energized together for first ratio; solenoid 14 alone for second; and neither energized for third. Shift control is responsive to a negative signal representing output speed, and a positive signal engine throttle (neither described) actuating an electronic control system 12 issuing shift signals to the bases of transistors 21, 41. Initially with zero signals at 21, 41, transistors 21, 41 are non-conducting, triggering amplifiers 45, 44 to energize both solenoids 14, 13 establishing first ratio. Appearance of a second speed signal at the transistor 41 switches it on, switching off the amplifier 44 and solenoid 13, leaving 14 energized alone for second ratio. A third speed signal additionally switches on the transistor 21 similarly switching off the amplifier 45 and solenoid 14, for third ratio. The circuit for synchronizing timing on 3-2 downshift is shown in the box 24, and has two transistors 31, 32, the former 31 being a PNP, whilst all the other transistors are NPN. In third ratio the preceding transistor 21 is conductive so that the potential at a junction 26 leading to the base of the PNP transistor 31 is at zero, causing transistor 31 and also 32 to conduct, grounding its collector. The 3-2 downshift signal turns off the transistor 21, energizing the shift-solenoid 14, as above described, and also immediately causing the junction 26 to assume battery voltage, which switches off the transistors 31 and 32, switching on the amplifier 44 and solenoid 13, which, with 14, establishes first ratio. When, after a predetermined interval, the charging of a capacitor 25 causes the voltage at the junction 26 to fall below the trigger potential of the transistor 31, the latter, and 32, both conduct again, switching off the amplifier 44 and solenoid 13, to cut out first ratio and establish second. This trigger potential is determined by the negative output speed signal biasing the collector of the transistor 31, increase in speed hence increasing the duration of first ratio application, which is also determined by the constants 22, 25, 30 of the timing circuit and by a diode 29. If a 3-2 downshift signal is received after less than the predetermined time following a 2-3 upshift, necessary to allow the potential of the junction 26 to reach the cut-off potential of the transistor 31, the synchronizing time interval is not produced.

Filed: 1974-11-21
Abstract: 1486470 Electric analogue signal stores TEXAS INSTRUMENTS Ltd 21 Nov 1974 50527/74 Heading G4G An electric analogue storage system comprises a multistage shifting register 5, e.g. a charge coupled device, in series with a variable gain amplfiier 10 (which in Fig. 1 has its output applicable to the input of the register 5 to constitute a recirculating store), a source 6 of reference signals which can be inserted into the series of input signals by an analogue gate 2. An analogue gate 9 at the output of the register 5 delivers the output to a sample and hold circuit 19 if the output corresponds to a circuit input signal or to a comparator 12 in the case of a reference signal for comparison with the initial value of the reference signal carried by line 13. The gain of the amplifier 10 is adjusted to compensate for variation of the reference signal in passing through the register 5 on the basis of the comparison through a sample and hold circuit 15. The sequence of operation is determined in Fig. 1 by a timing logic circuit 3. In Fig. 2 (not shown) the reference signals are chosen to be of distinctly different magnitude to the input signals and they are detected by this difference at the output of the register. The data input and output rates need not be identical and in Fig. 2 the reference signals are displaced by one bit in the sequence of inputs to the register with each cycle through the register. In Fig. 3 (not shown) the output of the system is taken from the output of the variable gain amplifier which is also connected to a comparator for determination of the variable gain. The analogue gates can comprise f.e.t.s., the reference sources zener or avalanche diodes and the variable gain amplifiers and comparators can be longtailed pair circuits.

Abstract: 1488689 Monitoring battery voltage; measuring voltage THOMSON-CSF 26 Nov 1974 [27 Nov 1973] 51258/74 Heading G1U In monitoring battery voltage e.g. while charging, the voltage is applied across two dividers, one providing a fixed fraction of the voltage and the other providing the battery voltage reduced by a fixed amount, these derived are compared and any difference used to illuminate an indicator. One divider comprises two equal resistances Rl, R2 and the other has a Zener diode Z, of threshold voltage equal to half the nominal battery voltage, in series with a third resistor R3 equal to the other two. According to the relative magnitudes of the voltages at A, B, one of diodes D1, D2 conducts and either L1 or L2 is illuminated. If the battery voltage is correct neither conducts. The diodes may be L.E.D.'s, in which case L1, L2 are omitted. In a modification a lamp is connected between A and B which glows when any difference voltage occurs. In a modified circuit Fig. 4 (not shown), a diode bridge is connected between A and B to apply the higher potential to the emitter and the lower potential to the base of a PNP transistor which when conducting illuminates a lamp via a switching transistor. In the Fig. 5 (not shown) embodiment, the diodes of Fig. 1 are replaced by the collectoremitter paths of transistors whose bases are connected to A and B respectively.
