Definitions
- the present invention relates to a method and to a device for switching off a vehicle starter automobile after starting the heat engine thereof.
- the effective starting speed of the engine is a function of many parameters and in particular of the state of wear of its components, its injection and ignition system or temperature ambient.
- the speed threshold at from which the starter is cut is generally very higher than the actual engine start speed. Therefore, in most cases, the starter works well beyond the time that would be required.
- a starter control device which cuts the starter when the ripples of its voltage or its intensity disappear.
- the voltage signal or intensity is sent on two channels, one of which is delayed. As long as there are ripples, both tracks are at different levels. When the ripples disappear, the two paths are the same level and the device cuts the starter.
- the control of the cut occurs, relative to the engine start thermal, with a delay time corresponding to the delay from the second line.
- An object of the invention is to propose a method and a device for cutting a starter from motor vehicle as soon as the heat engine thereof has reached its autonomy threshold, the start-up time being systematically reduced to just what is necessary.
- this object is achieved in that for each new ripple, a period of scrutiny of a duration which decreases with the increase of the frequency of the ripples and in that we cut the starter when no new ripple is detected in the last polling period.
- the invention also proposes, in order to implements this process, a device for controlling the shutdown of a motor vehicle starter comprising means for detecting ripples of a signal corresponding to the supply voltage of this starter or the intensity flowing through it, as well as means for controlling the cut-off of this starter when these ripples disappear, characterized in that it includes means for generating, for each new ripple, a scanning period of duration which decreases with increasing frequency of ripples and in that the means of cutting the starter cut off this one when no new ripple is not detected in the last period of scrutiny.
- FIG. 1 illustrates a device for controlling the supply of a starter motor D which comprises an electric motor M mounted between a supply terminal B + at the voltage of the vehicle battery and ground.
- This device comprises a contactor 1 mounted between the terminal B + of supply to the battery voltage and the starter D.
- This contactor 1 is a relay actuated by a winding 2. One of the ends of this winding 2 is connected to the supply terminal B + . Its other end is connected on the one hand to the source of a MOSFET transistor 3 and on the other hand to a coil 5 connected to ground.
- the drain of transistor 3 is connected to the supply terminal B + . Its gate is connected to the output of a unit 4, from which it receives a control voltage.
- transistor 3 could be replaced by any other type of switch.
- the unit 4 generates said control voltage as a function on the one hand of the undulations of the voltage of the supply terminal B + , and on the other hand of the position of the contactor actuated by the ignition key (switch 6).
- control unit 4 The processing carried out by the control unit 4 will now be described in detail with reference to Figures 2 and 3a to 3e.
- the input voltage of unit 4 (voltage of terminal B + ) is of the type illustrated in FIG. 3a. This voltage has, as long as the engine has not started, ripples whose frequency increases with the speed of said engine. These ripples disappear when the engine has started.
- this signal is filtered by a low-pass filter 7. Its continuous component is then deleted in stage 8.
- the signal then obtained is of the type of that of FIG. 3b, which corresponds to the filtered alternating component of the signal of Figure 3a.
- this signal is transformed into a niche signal of the type of Figure 3c.
- this stage 9 transforms the negative pulses of the signal at the output of stage 8 in positive pulses of constant amplitude and similarly duration than these negative impulses.
- the niche signal thus obtained at the output of stage 9 is sent on the one hand to a generator of pulses 10 and on the other hand on a timer 11.
- the generator 10 generates on the rising edges of the niche signal of short duration pulses (figure 3d), which reset the time delay generated by the timer 11 (figure 3d).
- the duration of the new Tsi delay generated is modified according to the duration Tci of the rectangular elementary signal at the output of stage 9, so as to be decreasing from one pulse to the other.
- This duration Tsi is chosen to be greater than two times the duration Tci of the last elementary signal rectangular, so that, as long as the input signal of unit 4 has ripples, a new ripple occurs before the end of each timer, the timer is then reset to zero by the impulse that corresponds to this new ripple.
- Unit 4 includes means 12 for inhibiting the blocking of transistor 3, as long as the time delay is thus maintained by the ripples of the input signal.
- the control voltage of the gate of transistor 3 is at a level (level 1 in Figure 3e), where it controls the closing of said transistor 3, so that the winding 2 is short-circuited and that contactor 1 is closed.
- the blocking circuit that constitutes the means 12 is also inhibited by reset pulses zero (figure 3d).
- the starter is therefore not stopped inadvertently by resetting the timer 11.
- the blocking of transistor 3 is no longer inhibited (signal of figure 3e at its level 0).
- the winding 2 is no longer short-circuited and contactor 1 is open. The starter is then cut off.
- the time between starting the engine and switching off the starter is particularly short, since it is less than the last time delay Tsi generated.
- FIG. 4 An example of a possible circuit for timer 11 is illustrated in FIG. 4.
- It has an integrated timing circuit 13, of a standard type, having an entry 13a of voltage-controlled duration control.
- a capacitor C is mounted between this input 13a and mass.
- This capacitor C is charged by a signal elementary in niche through a diode D and a resistance R, the charging voltage Uc across the capacitor C being transmitted, possibly by through an amplifier, at input 13a.
- Diode D prevents capacitor C from discharge when said elementary signal disappears.
- the reset signal drives a transistor T mounted between capacitor C and ground. He provokes rapid discharge of capacitor C via of said transistor T.
- the circuit 13 is therefore controlled by a voltage which corresponds to the average voltage of Uc and which is a function of the duration Tc of the last rectangular elementary signal received.
- FIG. 5c This is what has been illustrated in FIG. 5c, on which is shown the voltage Uc, the signal in niche and the reset pulses having been shown in Figures 5a and 5b.
- the average value of the voltage Uc is shown in lines mixed and is also indicated by the double arrows.
- FIG 4 there is also shown the input 13b time base of the timing circuit 13, as well as its control output 13c, which is maintained by a capacitor C1 at the control voltage of the transistor 3 is closed, as long as the time delay is not not finished, and which discharges the capacitor C1 at the end time delay.
- the input signal is the voltage taken from the electric motor supply terminal B + (figure 7a).
- This signal is sent to a low-pass filter 107 which rids this input signal of its parasites.
- the next floor 108 removes the component of the filtered signal.
- the alternative signal obtained is of the type illustrated in FIG. 7b.
- the signal at the output of this stage 108 is transmitted to a low level detector 120.
- This detector 120 generates a succession short pulses, calibrated in duration and amplitude ( Figure 7c). These pulses are sent to a counter 121 which also receives a signal from a clock 122 increment.
- Each pulse characterizes an end of phase of compression of the motor driven by the starter D.
- Counter 121 is reset to zero by each impulse. The value it reaches before each delivery to zero by a pulse characterizes the duration between two successive engine compressions.
- the pulses generated by the detector 120 of low level are also transmitted, with the signal incrementing the clock 122, to a down counter 124 which is reset with each new pulse.
- the value at which the down-counter 124 is reset is a function of the time between the two last pulses measured by the counter 121.
- the content Tc of counter 121 is transmitted to a multiplier operator 123 which multiplies it by a value k greater than 1.
- the value at output of multiplier 123 is transmitted to down counter 124.
- the scrutiny period thus defined by the countdown made by the downcounter 124 is therefore greater during the compression cycle of the engine.
- the down-counter 124 is reset before the end of its periods of scrutiny by impulses successively generated by the ripples of the signal input ( Figure 7d).
- the blocking of transistor 3 is then inhibited by the means 112 (signal of FIG. 7e at its level 1).
- the starter When the engine has started, the starter no longer transmits torque, so that ripples and impulses disappear.
- the absence pulses during a scan period means so that the engine has started.
- the means 112 are controlled from so as no longer to inhibit the blocking of the transistor command 3 (signal of figure 7e at its level 0).
- the contactor 1 goes to open state.
- the down-counter 124 is reset before resetting the counter 121.
- a delay circuit can be provided on the reset input of counter 121.
- Starting the system requires either a inhibition of the blocking circuit of transistor 3 during at least one compression, i.e. an initial loading of a value in the down-counter 124.
- the multiplier can be removed if we do the counting down at a frequency lower than that of counting. You can for this purpose insert a circuit divider, for example with flip-flop, between the clock 122 and the down-counter 124.
- the signal processed by unit 4 can be a signal corresponding to the intensity of the current passing through the starter D.
- This intensity signal can be obtained by measuring the voltage drop on conductive elements having an essentially ohmic characteristic, which are in series with the starter, such as power contacts of contactor 11, the connecting cable between the contactor 11 and the starter D, the ground return cable of the starter D, the power cable between the battery B + and the starter D.
- this current intensity can be obtained by measuring the voltage variations induced in a measuring coil crossed by one of the elements previously cited drivers.
- the signal pulses illustrated in figures 3d or 7c can be generated by a zero crossing detector of the component alternative of the filtered signal (instead of the low level or high level).
- the motor drive by the starter can be characterized by the derivative of the supply voltage or current.
- the derivative of the voltage is negative and the derivative of the current is positive.
- a monostable rocking device allows to trigger a signal at the beginning or at the end of the starter training period.
- a time delay variable of the type just described allows to adapt to the engine speed by cutting at most the starter early, without risking a stop command untimely.
- the speed is of the order of 300 to 400 revolutions / minute, or a duration between two successive pulses from 0.07 to 0.1 seconds.
- the speed can be 70 rpm only, that is to say a duration between two pulses of 0.43 seconds.
- a fixed time delay set to 0.43 seconds would drive the engine cold, but the order starter stop would be very late and could even intervene, especially when the engine is warm, with high motor speeds of the order of 1000 to 1500 revolutions / minute, i.e. a pinion speed for the starter 12,000 to 20,000 rpm.
- the starter breaking is independent of the characteristics of the engine, including the number of cylinders, characteristics injection and ignition, wear or adjustment condition engine, battery characteristics ...
- the proposed solution presents the advantage of being entirely autonomous and of not requiring no additional wiring during installation on the vehicle.
- the assembly constituted by a control device of the type proposed by the invention and its alternator is in interchangeable effect with a conventional starter.
- the starter proposed by the invention can be treated as a low control current, which allows us to consider many changes to the start command, for example: control by code entry, by pedal acceleration, etc.
