Definitions

  • the invention relates to a circuit arrangement for an engagement relay according to the preamble of the claim 1. (US-A-4873607)
  • engagement relays for in motor vehicles to use a starting device of an internal combustion engine. These engagement relays are used to provide a high Electricity with a relatively low control current to switch.
  • the high current starter current, the for starting an internal combustion engine Starter is required
  • the during the Starting process via the relay coil of the engagement relay In contrast, flowing current is, for example approx. 80 to 100 A.
  • start switch ignition lock
  • auxiliary relay assigns an auxiliary relay to the engagement relay, that by means of the starter switch of the motor vehicle can be actuated.
  • the disadvantage here is that not just an additional one for the additional auxiliary relay Installation space provided in the motor vehicle must be, but that this is an additional Consumers with a correspondingly high power loss represents.
  • the circuit arrangement according to the in Features mentioned claim 1 has the advantage that the auxiliary relay optimizes, that is, in particular be reduced in size can, so that the available installation space is also scalable.
  • the fact that one Control current influencing operating current of the auxiliary relay and / or control circuit is provided it is advantageous possible the operating current of the auxiliary relay to influence depending on selectable criteria that this for each operating state of the auxiliary relay only takes the size that is actually necessary, so that the power loss occurring at the auxiliary relay is reduced as much as possible. That’s it possible to integrate the auxiliary relay into the engagement relay, so that a compact unit is created.
  • control circuit is a clocked Control or current control circuit contains, with about the clock frequency and / or the duty cycle Amount of operating current depending on certain Operating states of the auxiliary relay can be determined is.
  • This advantageously makes it possible to reduce the operating current of the auxiliary relay changing operating conditions, for example an operating temperature and / or an armature position of the auxiliary relay.
  • the power loss of the auxiliary relay is reduced. This results in particular from a lowering of the operating current after the anchor of the Auxiliary relay has picked up or just this its movement along the path of movement started Has.
  • the auxiliary relay with a smaller, constant large clocked average operating current operate so that the different operating conditions by choosing a current setpoint of a clock frequency and / or the clock ratio are taken into account can.
  • the coil can now handle the maximum current be designed at the highest operating temperature.
  • FIG. 1 shows an overall designated 10 Circuit arrangement for a starter Internal combustion engine.
  • the circuit arrangement 10 has a switch-on element 12, for example an ignition lock or Start switch on with an electronic control unit 14 is connected.
  • the electronic control unit 14 has a control circuit 16 for one with the Control device 14 connected auxiliary relay 18.
  • a temperature detection circuit 20 associated with not here shown temperature sensors that are near the Auxiliary relay 18 or are arranged in the engine compartment, connected is.
  • the control circuit 16 includes one trigger stage 19 operating as a Schmitt trigger, the Response values a) and b) are changeable and the Feel the current profile at the output of control unit 14.
  • the control unit 14 has further ones that are not relevant here Circuit parts necessary for the function of the Motor vehicle are necessary. Not shown here Switch contacts of the auxiliary relay 18 are with connected to the windings of an engagement relay 22, the Switch contacts, also not shown, the Main circuit of a starter 24 on and turn off.
  • a switching current flows in Height of about 80 to 100 A.
  • FIG. 2 shows the setpoint and actual value of the operating current in the exemplary embodiment for controlling the operating current I according to FIG. 1.
  • the setpoint I soll of the operating current is reduced by the control circuit 16 to a lower value at the time t2.
  • the power loss can be reduced to approximately 25%, since a lower current is sufficient for the magnetic flux density required for the closed magnetic circuit.
  • This lower operating current I flows through the coil resistance of the coil and thus generates a lower power loss in the form of thermal energy compared to the higher operating current I before time t2.
  • control circuit 16 which clocks the operating current I in the control unit 14 on the one hand and the lowering of the operating current I on the other hand, is not to be considered in more detail here. However, it contains in addition to the trigger stage 19 is still a time stage for the time t2, switching the trigger level of the higher response values a1 and b1 off (a1) and switching on (b1) of the operating current I is on the lower thresholds a2 and b2. In the example, the setpoint of the operating current I is reduced from 25 A to 12 A after t2-30 ms.
  • the use of generally known multivibrators, precision Schmitt triggers or other suitable oscillator circuits, preferably also microprocessors, lends itself to the control circuit 16.
  • the time period t2 until the current is reduced is such that the relay armature surely lifts from its rest position at an earlier time t1.
  • the limit values of the operating current I is lower than the variable response values a and b of the trigger stage 19 with increasing temperature.
  • the time t2 until the operating current is reduced can be shortened with increasing temperature. In this way it is possible to compensate for the temperature-dependent friction of the moving relay armature and, if necessary, a temperature-dependent spring force of the armature return spring.
  • FIGs 3 to 6 are waveforms for the Clocking the operating current I shown.
  • the waveform is here with exact square-wave signals an exact duty cycle, i.e. the clock frequency, representable.
  • the control circuit 16 for example contain appropriately designed function generators.
  • the waveform with a 30% duty cycle shown that is, related per unit time (period) is the operating current I switched on in 30% of this time unit, while it is off for the remaining 70%.
  • a signal curve is shown in FIG a 60% duty cycle
  • Figure 5 a waveform with a 90% duty cycle
  • figure 6 shows a signal curve with a 100% duty cycle shown.
  • one of the lines of the operating current results I overlapped area and thus known the energy supplied to the coil.
  • Each the clock rate is smaller, i.e. the duty cycle On / Off, is selected, the smaller the supplied Energy and thus that occurring in the coil Power dissipation.
  • Auxiliary relay 18 can the duty cycle at the moment of switching Amount to 90% while it is on at time t2 50% is switched.
  • warmed auxiliary relay 18 can the at the moment Clocking with 100% take place at time t2 is switched to a 60% clock rate.
  • Means the control circuit 16 and the temperature detection circuit 20, the time t2 for the switching of the duty cycle can be influenced. For example, for a cold auxiliary relay 18 the time t2 at 30 msec, for a normal heated auxiliary relay 18 at time t2 at 25 msec and for a heated auxiliary relay 18 the time t2 is 15 msec.
  • auxiliary relay 18 operation of the auxiliary relay 18 is thus despite different operating conditions, in particular different operating temperatures, with one constant operating current mean value adjustable. By the clocking of the operating current I is beyond - as mentioned - a reduction in power loss of the auxiliary relay 18 causes.
  • an auxiliary starter relay is not only possible with the aid of the control circuit explained in FIGS. 1 and 2, but can also be implemented with a control and regulating circuit according to FIGS. 7 and 8.
  • the operating current of the control relay is clocked by a controller 17 via a clock stage in the control unit 14 'in such a way that the average current value which is established in the ratio of the clocking is regulated to a predetermined target value I target.
  • the actual value of the operating current I ist which is constantly changing due to the clocking, is sensed on the auxiliary relay 18.
  • the setpoint can now be lowered as a function of time after the relay is switched on or, with the aid of a further sensor 21, depending on the position of the auxiliary relay armature.
  • the winding is designed so that, for. B. at 0 c and regulation on Is1 a duty cycle of 60% is safe for a relay armature movement sufficient (duty cycles at the same Relay anchor position and Is2 z. B. 40%, at Is3 z. B. 20%).
  • a duty cycle of 100% for Is1 (66% for Is2, 33% for Is3).
  • the relay current is therefore basically independent of disturbance variables (such as temperature, battery voltage, etc.), but depending on the state of the relay armature (e.g. position, speed) and regulated by the magnetic force requirement.
  • the duty cycle is automatically set correctly by the controller.
