    This invention relates to an electronic vehicle clutch control system for automatically controlling a friction clutch disposed between an engine and a gearbox.
    The purpose of the invention is to improve reliability by compensating for the wear of the friction clutch.
    Fig. 1 shows an electro-hydraulic diagram of the clutch control system of Fig. 2, an electrical diagram of a wear compensator; FIG. 3 is a plot of the input and output signals of a single amplifier of the zero detection means;
    FIG. 4 is a graph showing the dependence of the input and output signals of another amplifier of the detection tool; Fig. 3 is a graph of input and output signals of the zero detection means, in Fig. 6 a diagram of the clutch control system, an embodiment; Fig. 7 is an electrical circuit of the error signal detection means valve, the command signal threshold detection means and the throttle position differentiator of FIG. The electrical circuit of the generator, the coincidence circuit, the trigger and the coarse adjustment means.
    The car clutch control system shown in FIG. 1 includes an engine speed sensor 1, which drives a signal V proportional to the engine speed, and a reference signal generator 2 that drives a reference signal V. The signal size V (j can be set equal to the signal value ,
    O delivered by sensor 1 at a certain number of engine revolutions, which can be set, for example, to 1000 rpm or can vary depending on the required engine torque (for example, the signal can be increased to a value equivalent to a greater number of engine revolutions for start-ups). It may
    It can be achieved by combining the signal of a throttle potentiometer, proportional to the size of the throttle bore, with a reference signal. The signal from the throttle potentiometer is inverted5. It is generated before it is combined with the reference signal V ,, but in this case it is used in its unprocessed state.
    Comparator 3 adopts reference
    0 signal V and signal V from the sensor
    engine speed and determines the difference between the two sigpals, giving an error signal. The error signal is positive when V (Y, and becomes. Sigotnegative when VH error is used to control the hydraulic actuator 4, which triggers slip 5 to change the number of engine revolutions followed by equalization of the signal V to the reference signal V "and reducing the error signal to zero. The error signal E arrives at the integrator 6, which causes the command signal C fed into the control loop of the clutch position. The integrator 6 has two modes of operation, depending on whether If a capacitor is integrated in the integrator into an error signal circuit or not, integrator 6 is an inverting and negative error signal, i.e. when V, ' causes a positive command signal C, the loop position control loop to receive at the integrator output. includes a comparator 7, which receives the command signal C and compares it with the signal S-. which, in compensation, is made of the signal of wear, the signal Sp feedback S and signal V, according to the position of the throttle clutch. The signal Sp is generated by a stroke sensor 8 responsive to the position of the clutch 5, and a signal V of throttle positions is generated by a potentiometer 9 connected to a throttle valve in the carburetor. The signal of the decoupler is supplied to the clutch actuator control device 10, which includes a filling ratio modulator used to control the valve 11 with a solenoid control. The valve 11 controls the flow of hydraulic fluid in the hydraulic actuator 4. The latter actuates the clutch 5, and the fill factor of the signal supplied to the valve 11 determines the flow velocity through the valve and, consequently, the speed of displacement of the hydraulic actuator 4 and therefore the engagement state of the clutch. The drive 4 is driven through a control loop to align the two signals C and fed to the comparator 7, so that the engagement state of the clutch is indicated by the value of the command signal C, When the signal V (more signal VP in the comparator 3 generates a signal .E errors, and subsequently formed command signal C triggers clutch 5 to cause the signal V to equalize (with the signal Vp, and reduce the error signal to zero. Wear compensation device 12 receives the signal and errors and command signal C, C unit 12 includes a zero detecting means 13, receiving an error signal E, a positive value detecting means 14, receiving a command signal C and circuits}, 15 matches, receiving signals from two means 13 and 14. The coincidence circuit also receives signals from transmission logic 15 and speed sensor 17 on the road, so that the coincidence circuit is open only when logic circuit 16 has selected the first gear and the road speed is below 6 mph, which corresponds to an engine speed of about 150 o b / min and below the number of revolutions at which full engagement occurs. The coincidence circuit 15 turns on oscillator 18 at 500 Hz when the error signal is zero and the command signal is positive. Binary counter 19 counts the number of oscillations missed by an open coincidence circuit 15, and digital-to-analog converter 20 produces a signal Sj proportional to the number of oscillations that goes to summing device 21. Figure 2 shows a detailed diagram of the compensation device. The zero detecting means 13 includes two amplifiers 22 and 23, one of which (22) is an inverting amplifier. The resistor 24 is connected in parallel to the amplifier 23. The clutch position control system operates as follows. When the car starts and the engine idles, the magnitude of the signal V, IU}, is higher than the magnitude of the signal V, which leads to a positive error signal and the HOMV exponent to the command signal C. When the engine speed increases, the signal V becomes equal to the signal Yr , the error signal E becomes equal to zero, and then when the signal V becomes larger than the signal V, 5 the error signal becomes negative. The clutch starts to turn on to keep the error signal at zero, at which point the command signal is positive. ten
    In the absence of a device to compensate for the monsters, the position of the clutch depends on the equilibrium between the signal from the sensor and the command signal Cj, and when the clutch discs wear out, the control system takes a longer period of time before the engine speed drops to 1000 rpm after the signal V will exceed signal V ,. This occurs 20 due to the fact that the feedback signal Sn is a reflection of the coupling state. To compensate for this, use wear compensation device 12.25.
    . During the first clutch engagement (at this point the car is moving at first speed and its speed is less than 6 mph), the command signal C is positive, since the signal Vf is greater than the signal V and the error signal E approaches zero. Then, the coincidence circuit 15 includes a generator 18, a counter 19, and a converter 35 20, and a signal is generated that is equivalent to the time during which the generator 18 is turned on by the coincidence circuit. For a new clutch disc, this account for the generator should be 40 minimum. As soon as sufficient engagement of the clutch is maintained to maintain the engine speed equal to RONR / min, the command signal C becomes zero 5 and the coincidence circuit 15 is turned off.
     Counter 19 counts the number of oscillations missed by the coincidence circuit, and digital-to-analog converter 20 outputs a continuously generated 5.0 output signal 5 with an amplitude proportional to the counting result, which is combined in the device 21 with the coupling position signal Sp to transform the signal Sp into signal S. This causes a decrease in the level of the command signal C by easily further engaging the coupling with
     in order to make the signal C equal to the signal S.
    When the clutch disc is worn further, the signal Sp increases and becomes equal to Sp + dSp, the oscillator count increases and the converter issues a new signal equivalent to the increased count, and the overall memory signal remains constant. The device is designed so that it should turn on and off with the ignition system car, i.e. it returns to its original position after each ride. However, the device can be connected in parallel with the battery, then it is installed on the first engagement of the new clutch disc and remains in the system until the new clutch disc is installed.
    The amplifier 23 (FIG. 3) works in such a way that the input signal, for example, the OQ value causes the amplifier to output the output signal, but does not turn it off until the input signal drops to 3. °. The hysteresis effect is determined by the size of the resistor 24, parallel connected to the amplifier.
    Amplifier 22 is an inverting amplifier in which the output is locked when the input signal reaches the value X - dX volts, and turns it back on when the input signal drops back to Z volts (Z is greater than Y) (see Fig.4). The hysteresis is determined by the value of the resistance connected in parallel to the amplifier.
    When the coincidence circuit 15 performs the operation and with the outputs of the two amplifiers 22 and 23 (FIG. 5), then the coincidence circuit only passes the signal during the period of time when both output signals of the amplifiers 22 and 23 are high. This causes the formation of a triggering range for the output signal between Jg ig (Figs. 3 and 3) when the input signal level drops so much that the wear detector is triggered only when the error signal approaches zero when the clutch is engaged.
    Now, if clutch tightening takes place with the throttle fully open, the clutch disc must be in rigid engagement with the leading elements and the signal level S, feedback must be greater than the normal level, for example. , and therefore the signal S. is larger than it should be. To compensate for this, the signal from the throttles V, which decreases as the throttles increase, is combined with the signal S ,. At a vehicle speed greater than 6 mph, the coincidence circuit is locked and the wear compensation device 12 is turned on. This ensures that the device does not function at every change in gear. By having a vehicle speed limit of 6 mph, which is lower than the corresponding engine speed at which the clutch is fully engaged, it is possible to ensure that the signal is in a position at wherein the clutch is in a state of slippage with leading surfaces. In the variant of the device ignition (Fig.6-8), the common components with the components of the described system have the same designations. The comparator 3 receives the signal V corresponding to the engine speed, and the reference signal V ,, and measures the difference between these two signals, producing an error signal E. When V (- Vg, the error signal is greater than zero, when V, V, the error signal is zero, and when V Vp, the error signal is less than zero .. When the signal is V, more than the V signal, the error signal E is generated in the comparator 3 and the following the command signal C triggers clutch 5 to equalize Vy with V and reduce the error signal to zero. Wear compensation device 25 receives error signal E and 1 signal command C. Device 25 activates detector 26, which detects when error signal is zero or slightly less, the signal detector 27 is high level, which receives the command signal C and the first coincidence circuit 28, which receives signals from two means 26 and 27. The coincidence circuit 28 also receives signals from the gearbox logic 16 and the speed detector 17 so that the coincidence circuit 28 opens only when logic circuit 16 selects the first gear and the road speed is less than 6 mph. Circuit 28 also receives the signal of position differentiator 29 throttle, which is connected to a potentiometer connected to the throttle valve in the carb vehicle Ator. In this system, the potentiometer 9 of the throttles, which is present in the first described system, is connected not to the feedback circuit through which the feedback signal S is received, but through the resistor 30 to the input of the detector means 27 of the command signal. The coincidence circuit 28 includes a torque type 31. at 1000 Hz, when the error signal approaches zero and the command signal C is high and all other command signals are correct. A signal with a frequency of 1000 Hz from generator 31 is fed to divider 32, which reduces the signal frequency to 100 Hz. A binary counter 19 and a digital-to-analog converter 20 calculate the number of oscillations for which the coincidence circuit 28 is open, and outputs a signal dS proportional to the number of oscillations missed by the coincidence circuit. . This is a fine adjustment for the compensator. The dS,} signal is combined with the dS signal from the second coincidence circuit 33 and subsequently combined with the feedback signal SP from the sensor 8 in the summation node 34 to generate a bass: Sf that is fed to the comparator 7. The signal from the generator 31 also supplied to the second coincidence circuit 33, which also receives a signal from the synchronizer 35 and comparator 36. A signal from the reference signal generator 37 and a signal S are supplied to the inputs of the comparator 36. The coincidence circuit 33 is open when the signal from the synchronizer arrives Twa 35 (about 0.35) and open the comparator 36. The comparator is locked when the value of the signal S approaches to the target value of the signal from oscillator 37 postupakschego reference signal. This is done by means of a coarse adjustment of the clutch position. Fig. 8 shows detailed diagrams of the generator 31 and the synchronizing device 35. The circuit compensates for engineering tolerances in the clutch drive mechanism. When the clutch stroke sensor 8 is installed on the vehicle's kopo6Ke gears (not shown), mechanically, the tolerances will cause the tolerance sensor on its feedback signal relative to the clutch position. When the sensor is mounted on a new clutch, it is set to a position in which the clutch release bearing only touches the spring-loaded fingers of the clutch diaphragm (or may be a clutch release tag). The generator 37 of the reference signal of the clutch position is set to a predetermined voltage value above zero to ensure the circuit is set to a state where the clutch is more fully engaged. When you turn on the vehicle ignition. the circuit will quickly produce a signal S equal to a predetermined voltage, so that when the clutch disc is worn, the magnitude of the signal Sf is maintained at the level corresponding to the full engagement state. When the vehicle is switched on, the synchronization device 35 will keep the coincidence circuit 33 open until its capacitor 38 is charged and does not prohibit this coincidence circuit. As long as the coincidence circuit 33 is open, the generator 31 sends a signal with a frequency of 1000 Hz directly to counter 39, producing a dSyy signal until comparator 36 blocks the 33 coincidence circuit. The synchro device 35 works in such a way that it remains open for a longer period of time than is required for the comparator 36 to be opened. Therefore, each time the ignition switch actuates the driver, this circuit will issue an initial signal dS- change as the clutch disc wears. The signal will provide a coarse positioning of the clutch disc in the correct position to maintain a constant engine speed when the clutch is engaged, and the dSw signal will provide the final per: alignment of the clutch position. In some cases, it is possible to compensate for the wear of the clutch only by means of a coarse adjustment of the position. Fig. 7 shows in detail the detector means 26, which includes a threshold detector 40, which receives the error signal E and compares it with a fixed reference voltage, which is slightly greater than zero. When the detector 40 is triggered by an error signal approaching zero, or becomes below zero, its output signal increases and opens a coincidence circuit 28 provided all other conditions are met for other input signals. When the output signal of the detector 40 rises, it causes the capacitor 41 to charge, causing an increase in the input signal to the second threshold detector 42. The latter is an inverting amplifier and its output signal is usually high level reduced when the amplifier is started. Then, the output signal from the second detector 42 reduces the level of the output signal from the first detector 40 and locks the coincidence circuit 28. The time period for charging the capacitor 41, during which both outputs from the detectors are high, is approximately 1 second. If the error signal E suddenly increases, i.e. The V signal will fall below the reference voltage. Vo "detector 40 will turn off the coincidence circuit 28. This causes an immediate discharge of the capacitor 41 through the transistor 43. If the error signal subsequently decreases, the capacitor 41 will require a full time (1 s) to charge. . The detector means 27 includes a threshold detector, which receives a reference signal (zero) and a combined signal, which consists of the signal from the droplet potentiometer Vy and the command signal C, the magnitude of the reference voltage is always less than the magnitude of the combined command signal and the position signal of the dross when the number of turns engine revving 1000 rpm As the command signal C increases, the detector is triggered and its output opens the coincidence circuit 28 when all other requirements for the input signals are met. The differentiator 29 includes an inverting threshold detector 44, the output of which is connected to the coincidence circuit 28. The output signal of the detector 44 is usually large enough to keep the -28 coincidence circuit open, but it lowers on startup, closing the coincidence circuit. The positive input of the detector 44 receives the reference voltage (:; zero), and the negative input receives the signal from the throttle potentiometer through the capacitor 45 and resistance 46. B the acceleration flow decreases while the output signal of the potentiometer decreases, the capacitor 45 effectively prevents the triggering of the threshold detector 44 When the accelerator is suddenly released, the signal from the throttle potentiometer increases and the capacitor 45 appears on the input of the high-level 4-D signal detector, causing it to start and lower its output signal, I eat the most immediate locking of the coincidence circuit. This prevents the number of vibrations in the wear compensator to be passed by the circuit during the moments when the engine speed exceeds the reference number due to engine inertia when the throttle closes. If a pitch flush occurs with a large throttle bore, the clutch disc engages fully with the lead and the SP signal is larger than it should be (for example, becomes Sp + dSp), and therefore the nose compensator 25 will work and Sy more than it should be. To prevent this, the signal from the potentiometer 9 throttles is combined with the command signal 8 supplied to the detector means 27, TciK decreases as the signal from the throttles when I open the throttles and the command signal increases with increasing signal V above signal V, then the vibrational signal remains almost constant and locks the matching circuit 28 when the wear signal is low. The clutch positioning system works. 7-2 When the vehicle starts and the engine is idling, the voltage from the engine RPM sensor V is less than the reference signal voltage V-. This leads to a large error signal E and a low level of the command signal C. As the engine speed increases, the signal V. becomes equal to the signal V., the signal E op; the unit tends to zero and then, as soon as V exceeds Vj, the error signal becomes smaller. The clutch starts to turn on Erzhanov zero error signal at this moment the command signal is at a high level. When the ignition is initially switched on (as described), the wear compensator gives the initial signal dS vjy, during the first engagement of the clutch, when the clutch starts to 1; engage (at this moment the first gear is switched on in the vehicle and the speed is less than 6 miles / hour), the command signal C has a high level, since V exceeds V and the error signal E approaches zero. Unless detector 44 in differentiator 29 has been triggered, then the coincidence circuit 28 turns on generator 31 for a period of time until any of the signals E or C changes to lock the coincidence circuit 28. Counting the number of oscillations missed by circuit 28 from generator 31 causes a signal dS, which is combined with a signal dS to form a wear signal 5. For a new clutch disc, this count is the number of oscillations from the generator for the signal dS Y | should be minimal. When the clutch is sufficiently engaged to maintain equality, the command signal vanishes and the coincidence circuit 28 closes. Counter 19 counts the number of oscillations for which both coincidence circuits 28 and 33 were open and generates a fixed spin code, which is proportional to the count result, which is then combined into Sum 34 to the feedback signal Sp, generating the Sr signal. This makes it possible to further easily hook up the coupling for the given signal y, thereby maintaining engine speed is low at which the clutch engages almost continuously, although the clutch disc is worn. As the clutch wear increases, the number of oscillations from the generator that the 28 I 26 1 557 overlap will increase will cause an increased dSiy signal, and thus an increased signal 5 la 5,
