Definitions
- the invention relates to a method and a device to control a consumer.
- Methods and devices for controlling a consumer are known. Usually the control of Consumers between at least two control phases distinguished.
- the starting current phase or the second phase can be the consumer with an increased current (Pull-in current) or with a clocked voltage with large Period duration controlled.
- the holding current phase the Also called the first phase, the consumer with a lower current (holding current) and / or with a clocked signal with a shorter period controlled. Due to the high current in the starting current phase a quick reaction of the consumer is achieved.
- the consumers of one Microprocessor controlled via an output stage. For this acts on at least one output of the microprocessor Power stage with a control signal. Depending on this Signal sends the power to the consumer with electricity or prevents the flow of electricity in the consumer.
- the Controlling consumers in a timed manner is a special one Microprocessor output required, the one provides pulse width modulated signal. Usually such outputs are only available to a limited extent
- the invention is based, with one Method of a device for controlling a consumer a way to show the consumer with a to control clocked signal, the lowest possible Number of outputs of the microprocessor are required which provide a pulse width modulated signal.
- a first signal (H) the duration of the first Control phase determines that at least in the first Control phase a clocked control takes place, and that a control signal (S) for controlling a consumer based on a logical combination of the first signal (H) and a PWM signal (PWM) can be specified with a small number of PWM-compatible outputs, in particular only with a corresponding output, a larger one Number of consumers can be controlled.

- the PWM signal Frequency and / or the period of the clocked Control determined.
- the PWM signal can be output.
- the respective Control signal can be determined.
- a simple logic unit results from the fact that the Signals are linked in such a way that in the second Control phase, the second signal (A) assumes a level at which is a current flow through the consumer, the Current flow through the consumer regardless of the first Signal (H) and the PWM signal (PWM) takes place.
- the first Control phase is the current flow through the consumer depending on the first signal (H) and the PWM signal, where the current flow through the consumer regardless of that second signal (A).
- FIG. 1 shows a block diagram of the invention Device
- Figure 2 is a block diagram of a logic circuit the device according to the invention and FIG. 3 different signals plotted over time.
- the device according to the invention is exemplary in FIG shown.
- a consumer is labeled 100.
- the The consumer is Ubat with a first connection a supply voltage and via an output stage 110 connected to a second connection of the supply voltage.
- the consumer is shown in the Embodiment around a low-resistance solenoid valve.
- the Power amplifier 110 is in the illustrated embodiment as Switching means implemented. This switching means is like this trained that the current flow through the consumer 100th releases when there is a low signal at its input Signal level is present. There is a signal with a high level on, it blocks the flow of electricity through the consumer.
- the output stage 110 is connected by a logic circuit 120 Control signals S1, S2, S3 and S4 are applied.
- the logic circuit is in turn operated by a microprocessor 130 with control signals A1, H1, A2, H2, A3, H3, A4 and H4 as well as with a pulse width modulated signal (PWM signal) PWM applied.
- the microprocessor 130 processes Output signals from various sensors 140
- Control signals A1 to A4 and H1 to H4 are from Outputs provided that are only a high or assume a low signal level for a certain time can.
- the PWM signal is from an output provided a clocked signal with a predeterminable period duration and / or a predefinable period Frequency. Stand with usual microprocessors such PWM outputs are only available in limited numbers.
- the Logic circuit Starting from the control signals A1 and H1, the Logic circuit the signal S1 to act on the Power amplifier. In general, the signals A, H for formation of the respective signal S.
- Control signals S1 to S4 and the corresponding one Signals A1, H1 to A4, H4 are shown for four consumers.
- the procedure according to the invention is not based on the Limited to four consumers. You can with everyone any number of consumers can be applied.
- FIG. 1 is also merely a consumer 100 and a switching means of the output stage 110 shown.
- the logic circuit is shown in more detail in FIG. 2. Components already described in FIG. 1 are included corresponding reference numerals.
- the signal H1 and the signal PWM reach an OR gate 211. Das Output signal of the OR gate arrives just like that Signal A1 to an AND gate 212.
- the output signal of the AND gate arrives at output stage 110 as signal S1.
- the signal H2 and the signal PWM reach an OR gate 221.
- the output signal of the OR gate arrives just like the signal A2 to an AND gate 222.
- Das The output signal of the AND gate arrives as signal S2 Power amplifier 110.
- the signal H3 and the signal PWM reach an OR gate 231.
- the output signal of the OR gate arrives as well as the signal A3 to an AND gate 232.
- Das Output signal of the AND gate arrives as signal S3 Power amplifier 110.
- the signal H4 and the signal PWM reach an OR gate 241.
- the output signal of the OR gate arrives just like the A4 signal to an AND gate 242.
- Das Output signal of the AND gate arrives as signal S4 Power amplifier 110.
- the various signals are on one Example plotted over time t.
- the signal A in part B the signal H, in part 3c the PWM signal, in part 3d the Control signal S for the output stage and in sub-figure 3e Current I flowing through the consumer 100 is plotted.
- a current profile as shown in sub-figure 3e is shown as an example. It is provided that the consumer at the start of the control in with a high current value, the starting current becomes. This is preferably done in the period between the Instants t1 and t2. Then the Holding current phase in which the consumer with a smaller medium current is applied. For this, the Consumers are driven preferably clocked.
- During the holding current phase is a clocking with a preferably fixed frequency, for example 1 kHz, required.
- the duty cycle or the Period of the clocked PWM signal is thereby preferably depending on various parameters, in particular sensor signals specified by the microcomputer.
- a corresponding signal can be with a PWM output pass on from the microprocessor directly to the power amplifier 110.
- microprocessors are the number of PWM output limited. It is with the procedure according to the invention possible with a PWM output and a larger number normal outputs a corresponding control of the To realize consumer.
- microprocessor 130 sets 110 for each output stage Signal A and a signal H ready.
- the signal A which is also called second signal can determine the duration the starting current phase.
- a first signal H determines the duration the holding current phase.
- the third signal PWM determines that Duty cycle and / or the frequency of activation during the holding current phase.
- the microprocessor determines that Duty cycle or the period depends of various operating parameters, for example with the sensors 140 can be detected.
- the logic circuit is designed such that when present of signal A the final stage in its conductive state transforms. This is in the period between times t1 and t2 the case. Regardless of the signals H and PWM takes at low level of signal A, signal S also low level, this low level one Current flow in the consumer results.
- the signal A assumes a high level, it depends on State of the signal H, whether the final stage is in its conductive or locked state. This means, only if both the PWM signal and the signal H their assume a low signal level, which indicates that the output stage should conduct, the signal S assumes the low level, the causes the power amplifier to be in its conductive state and electricity flows through the consumer.
- signal A and signal H take its high level. This has the consequence that the final stage regardless of the PWM signal in their non-conductive State, and that the signal S is at a high level takes.
- the signal A at a low level this means that the Power amplifier.
- the signal S independent of the signal H and the signal PWM Level indicates that the output stage conducts. That is, the signal S takes a lower in the period between t1 to t2 Level on. As a result, the current I through the Consumers be on quickly between times t1 and t2 Starting current increases.
- signal A takes on such a level indicates that the output stage 110 is not conducting and takes the H signal such a level that the power amplifier conducts. While this period takes the signal S to control the Only at such a level that the power amplifier conducts when both signal H and signal PWM assume a level that leads to a conductive output stage. This means that this is determined during the period t2 and t3 Signal H and the signal PWM the state of the output stage.
- the output stage is clocked depending on the PWM signal controlled.
- the procedure according to the invention is not limited to one Control with two phases limited. You can at Controls with any number of phases are used be in which at least in one of the phases clocked control takes place.
