Description

The The invention relates to a device, a control unit, an actuating unit and a method and computer program product for control an actuator for a motor vehicle.

It In the prior art, various devices are for control an actuator known. These are usually switching devices such as push button, rocker switch, pushbutton or Pull switch, each having a defined on or off switching state taking. Such switching devices are in particular for Control of an electric window used. typically, must here the switching device for the entire time, the Actuating process, actuated. To this operating time preferably to minimize, or to avoid distraction of the occupant is the adjustment speed of a conventional power window relatively large, so that the maximum adjustment, that is, a complete opening or closing of the Window, can be covered within a few seconds. With help such a switching device, which only over a single adjustment speed features, it is impossible make a fine positioning of the window.

traditionally, be the adjustment speeds of electrically operated windows in the motor vehicle 80-160 millimeters per second. For example, the inmate wants Move a window by less than ten millimeters, so would the operating time the corresponding switching device in the range of a few hundredths Seconds. In addition, must the drive motors for the actuator have a relatively high torque, which within such a short operating time not completely set up can be.

With Help a conventional Switching device for Electric windows, it is thus not possible, a fine positioning make the window of the motor vehicle. Such switching devices, in which the adjustment of the window in dependence set by the operating time will appear for the solution the task of fine positioning of a window pane as unsuitable.

In the DE 19848941 C2 an operating device for an electric window of a motor vehicle is proposed by means of a rotary switch. In this case, each rotation angle α of the rotary switch is associated with a predetermined adjustment path of the window pane, which increases non-linearly with the rotation angle α.

Preferably has the rotary switch over six single rest positions and a neutral position, in which he springs back. Small angles of rotation of the switch become relatively small and larger angles of rotation but disproportionately size Assigned adjustment paths of the window. This thus allows a fine adjustment and at the same time the choice of larger adjustment paths, like them for a quick complete Shut down or open of the window are necessary.

adversely Here is that the rotary switch over a total of seven different Positions. The operating concept for the window becomes relatively complex and is no longer intuitive. In addition, the targeted dialing a certain speed level for the actuator relatively difficult and requires some practice of the occupant. In particular, by vibrations of the motor vehicle, as they occur when driving on uneven roads, the susceptibility to errors for the Selection of different adjustment speeds for the actuator relative large.

adversely is still that by accidentally pressing the Rotary switch a relatively large Angle of rotation and thus a relatively large displacement of the window can be set unintentionally.

In the DE 19548659C1 a further switching device for controlling an adjustment is described. Here, the actuator is provided as an endlessly rotatable wheel without absolute zero position and without defined on and off states. By an incremental rotation of the rotary wheel control signals are transmitted in the form of electrical pulse trains to a control unit. This control unit converts the control signals into control commands for the drive motor of the adjustment drive. The control signals are generated as a function of the dynamics and / or the degree of adjustment of the actuating element. According to the dynamics of the adjustment of the actuating element thus takes place a fast or slow adjustment of the object to be adjusted.

The Control unit allows thus an assignment of different rotational speeds of the rotary wheel with different adjustment speeds of the window. So can for example, crossing interpreted a certain rotational speed of the rotary wheel to the effect the window with the maximum adjustment speed in one End position to drive.

The processing of the control signals by the control unit takes place sequentially. That is, while the window is being moved to an end position, the device does not respond to a continuous one Actuation of the rotary wheel. Only after reaching the end position of the window further control signals are processed by the control unit and possibly passed as control commands to the drive motor.

adversely in this device is that the drive of the drive motor is decoupled by the control unit from the operation of the rotary wheel. Is an accidental operation of the rotary wheel as a complete opening or Shut down of the window interpreted by the control unit, so the user has no possibility manually interrupt the continuous adjustment process of the window and counteract if necessary.

One Another disadvantage is that the targeted selection of different Adjustment speeds for the window from the user some practice requires. This has a negative effect on the ease of use of this Device off. The targeted setting of a desired Adjustment speed of the window is also unfavorable here Conditions, such as vibrations, only conditionally possible.

Of the Invention is in contrast the task is based, an improved device and an improved Control and operating unit, a method and a corresponding computer program product for Fine positioning of adjustable openings in motor vehicles to disposal to provide the largest possible Influence of the user as well as an intuitive and easy handling enable.

The The objects underlying the invention are each with the Characteristics of the independent claims solved. Preferred embodiments of the invention are in the dependent claims specified.

The inventive device has two Actuating means the on actuation Transmit control signals to a control unit. According to this Control signals calculated by the control unit drive sequences for the actuator. According to this Control sequences takes over the actuator positioning an object to be positioned, which in a position corresponding to the control signals and / or with a speed corresponding to the control signals in a predetermined Position is positioned.

The Both control signals are different from the two Actuator generated. The first control signal hangs only from the operating time of the first control means while the second control signal from the adjustment or from the dynamics the adjustment of the second actuating means depends. According to the invention the two control signals different adjustment speeds for the Assigned actuator. The first control signal is a maximum adjustment speed and the second control signal a assigned significantly reduced adjustment speed. Thus, can with the help of the first actuating means a quick, relatively rough positioning of the to be positioned Object be made and with the help of the second actuator can be a more accurate, at a slower speed Positioning be made.

To a preferred embodiment of Invention has the time-dependent Control signal a higher priority as that dependent on the adjustment Control signal of the second actuating means. As a result, the device may promptly respond to an actuation of the time-dependent actuating means react. this makes possible an immediate intervention of the user in the control, what in the prior art with a complete electronic decoupling of the actuator of the control is not possible. There are control signals from the control unit is interpreted in control sequences, their implementation takes some time. While however, further control signals are ignored in this implementation.

According to the invention processes the two control signals in the control unit in such a way so that the displacement of the object to be adjusted proportional at the time of operation of the first actuating means or proportional to the adjustment of the second actuating means is.

To a further embodiment The invention can be the adjustment of the object to be positioned after a nonlinear relationship at the time of operation or to the adjustment of the actuating means be assigned. For example, if the operation of the second actuating means with a certain speed, the result may be Control signal from the control unit to control the actuator at a greater speed be interpreted.

Consequently the actuator can also with the help of the second actuating means be driven at a reduced speed. Since that second actuating means by means of the control signal the degree of its adjustment as well Dynamics can transmit to the control unit this subsequently the actuator with dynamically varying control sequences drive. So with the help of the control unit a certain adjustment speed of the actuating means converted into a predetermined adjustment speed of the actuator become.

To a further embodiment the invention features the device over a position detection means for the object to be adjusted. According to the invention determines this position detection means the absolute position of the object to be adjusted and passes this to the control unit. The position detecting means can with Help from usual Hall sensors and magnets are designed so that the direction of rotation as well as the angle of rotation of the actuator can be determined.

To a further embodiment According to the invention, the control unit combines the two control signals the actuating means with the data provided by the surveyor absolute position of the object to be adjusted. Depending on this absolute position and the predetermined by the control signals Target position of the object to be adjusted, the control of the Actuator by the control unit according to a temporal and / or local Speed profile done.

is the predetermined displacement of the object to be adjusted relative large, that would be Object first with the maximum available standing speed and just before reaching its target position moved at a successively reduced speed. alternative can reduce speed even after some Adjustment made.

These dynamic adaptation of the adjustment speed is particularly advantageous if the predetermined by the control signals target position beyond a given by the device end position to be adjusted Object lies. On the one hand, the control unit can prevent this that the object is over an end position can be moved out. On the other hand, one can noisy, sometimes damaging the device Hitting the object with undiminished speed to one End position of the device can be prevented.

is however, by the second actuating means given displacement relatively low, this is done by the control unit is interpreted as a fine positioning of the object to be adjusted. In this case, the actuator with its minimum or one driven relatively low speed. Thus it becomes the Allows users to a fine positioning of the object to be adjusted in a simple Make way.

To a further embodiment the invention, the control of the actuator during the activity the second actuating means be dynamically adjusted. Is the adjustment speed of the second actuating means first relatively low, so is the actuator by the control unit first driven at a relatively low speed.

Becomes the second actuating means however during this adjustment process with a larger adjustment speed operated by the user, so determines the control unit depending from the current absolute position of the object to be adjusted and from the received control signal, a greater speed for the actuator, with this one finally is controlled. Thus, a continuously varying operation of the actuating element by the user in a correspondingly varying control implemented the actuator.

in the Contrary to the prior art, which is a sequential processing the control signals in the control unit provides and it does not allows during the execution a control to receive further control signals or these To process, here is the control of the actuator to each Time adaptive to the control signals of the actuating means. In which the control unit permanently a predetermined by the control signals target or target position with the determined by the position detecting means actual position of the object to be adjusted, an occurring difference between Target and actual position of the object to be adjusted by variable adjustment of the adjustment speed be minimized by the control unit.

Especially It should be emphasized here that the control signals of the first actuating means always a higher one priority having the control signals of the second actuator. There the control signal of the first actuating means from the operating time depends the actuator is immediately and for the duration of actuation of the first actuating means driven at maximum speed. Thus, upon actuation of the first actuating means an immediate positioning of the object to be adjusted with maximum Speed, independent from an already processed control signal of the second actuating means.

To a further preferred embodiment The invention is the first actuating means designed in the form of a rocker, tactile, snap, push or pull switch. When pressed by the user, the switch is placed in an ON position. As long as the switch is in this ON position, it transmits control signals to the control unit, which for the continuation of the operation activates the actuator at maximum speed.

Essentially, this switch performs the function of controlling the actuator at the highest possible speed. Such scarf ter find standard for controlling conventional actuators such as for electric windows in the vehicle use.

To a further preferred embodiment the invention, the actuator can be placed in an automatic run which, for example, in an "automatically to" or "automatically on" function of the actuator empties. This means the actuator is in automatic mode in a defined end position method. The triggering the automatic run can be done both with the help of the first and with Help the second actuator triggered become.

to release the automatic run using the first actuating means, this is preferably formed with different switching levels. A displacement of the first actuating means in an appropriate switching level finally causes an automatic run of the Actuator. If the first actuating means is repeatedly actuated while the actuator is still in automatic mode, this can be for Consequence that the automatic run is canceled, or that the Automatic run aborted and a new action is triggered. If, however, the second actuator while actuates such an automatic run, so no further action is triggered, i. the actuation of the second actuating element is ignored. In other words, the first activity moniker has priority across from the second actuating means

A different possibility such an automatic run can by the adjustment of the second actuating means be realized, with a certain desired position of the actuator is given, in which the object to be adjusted is to move. Will while of such an initiated automatic run the first actuating means actuated, so the automatic run is in favor of the first actuating means interrupted and corresponding to the first actuating means Action is triggered.

Becomes while during of such an initiated automatic run, the second actuating means repeatedly pressed, so the automatic run is affected by this repeated actuation, i.e. For example, it will be the target position of the object to be reached readjusted or the automatic run otherwise suitable, for example with regard to the adjustment speed.

To a further preferred embodiment The invention is the second operating medium in the form of an actuating element designed with rotary or sliding function. This can be independent of the operating time a rotation angle or a displacement distance are selected by the user, the with the help of the control signals to be generated in the control unit be converted into a predetermined desired position of the object to be moved. additionally this can be an operating time of the second actuating means be taken into account for adjusting a rotation angle or displacement. From this resulting adjustment speed of the second actuating means can thus from the control unit a Verstellgeschwindigkeiten for the Actuator can be generated.

To a preferred embodiment of Invention are the two actuating means in a single actuator integrated. For example, a rotary or sliding switch be placed in the top of a rocker, tactile or snap-action switch. A depression or pulling on the actuator thus generates a time-dependent Control signal while turning or moving the rotary or slide switch dependent on the degree of the adjustment Control signal for the control unit generates.

To a further embodiment The invention is the second actuating means as an endless rotatable wheel with equidistant locking positions educated. If the user turns on this wheel, then pro passed detent position two electrical pulse trains as a control signal generated. The two pulse sequences generated in this way are offset in time, that is, they are out of phase with each other.

With Help this phase shift, the direction of rotation of the rotary wheel for the Control unit to be coded. The sign of this phase shift thus defines the direction of rotation of the wheel. Becomes the first pulse train detected in time before the second pulse train by the control unit, this is interpreted as a clockwise rotation, for example. In the reverse Case when the second pulse train detected before the first pulse train is, this means a left-handed direction of rotation. Thereby, that the wheel only when passing through a detent position defined Pulse train to the control unit is only an incremental Rotation of the rotary wheel independently from the absolute angular position of the rotary wheel for the generation of control signals crucial.

The The target position of the object to be adjusted is in this case from the Number of traversed rest position, that is, from the number of generated determined by electrical pulses. Is however a dynamic control desired the actuator, so can from the absolute number of the pulses as well as their Frequency a dynamic adjustment speed for that too positioning object can be determined.

According to another embodiment of the Invention are modulated by the control unit generated control sequences for the adjustment according to the pulse width modulation method. A pulse width modulation module converts these pulse sequences generated by the control unit into analog voltage signals for the drive motor of the actuator. The module for pulse width modulation can also be integrated in the actuator.

The Modulation of an analog voltage signal based on the pulse width modulation method on a temporal subdivision corresponding to the amplitude Signal within a given clock frequency. The pulse width modulated signal has only two states, which are referred to here as the 0th and 1st state. A pulse width modulated Signal, which for the entire duration of a clock interval in the first state is equal a maximum voltage amplitude. Is the signal already following? half of a clock interval in the 0th state, this corresponds to a voltage value, the half corresponds to the maximum value.

According to the invention, the Device for fine positioning of an actuator for various Actuators are used in the motor vehicle. After a preferred embodiment The invention is the actuator for driving an electric Window lifter or a sunroof. Further embodiments refer to electrically adjustable exterior mirrors or electric adjustable vehicle seats.

Especially while Driving with partially open window arise in dependence from the opening width a window as well as the speed of the vehicle air turbulence, the sometimes quite loud noises in the vehicle interior. These are considered by the occupant uncomfortable and could feel by slight change the opening width of the window. While conventional switching devices for electrical Power windows such slight change the window opening is not enable, the invention allows a targeted setting arbitrarily smaller Adjustment paths of the window.

To a further preferred embodiment The invention relates to the control signals received by the control unit only in drive sequences for implemented the actuator when different release elements this allow. Such a release element can, for example, by the ignition or pronounced by a selection button of the automobile.

If desired by the manufacturer or the user, an electrical Windows are operated only with activated ignition of the motor vehicle. A switched off ignition would thus the opening or close prevent a window. Furthermore, with the help of appropriate Release elements, for example, a parental control in the simplest Way to be implemented. So the activation of a or more selected ones Windows are disabled. Furthermore, different operating modes the control unit are selected for example by an on-board electronics, so that different dynamic adjustment modes of the window only in certain driving situations selected can be. So could For example, a quick complete opening of the window at high Speed, which can lead to a distraction of the occupant, be prevented.

The 1 shows a block diagram of an apparatus for fine positioning of a power window for a motor vehicle. Here are two actuators in the form of a rocker or tactile or snap-action switch 100 or in the form of a rotary wheel 102 independently from one another control unit 110 via electrical connections 120 connected. The ignition of the motor vehicle 104 , a selection module 106 as well as other modules not explicitly listed here are separate with the help of electrical connections 120 with the control unit 110 also connected.

The rocker switch 100 and the wheel 102 are in a multi-function switch 108 integrated. The control unit 110 is with an electrical connection 122 with a pulse width modulation module 118 connected. This in turn is connected to an electrical connection 124 with an actuator 112 connected.

The actuator 112 is by means of a mechanical coupling 126 with a window of the motor vehicle 114 connected. Further, a position sensor 116 on the actuator 112 arranged. Finally, the position sensor 116 with the help of another electrical connection 130 with the control unit 110 connected.

The control unit 110 includes a program module 140 which is the result of the electrical connections 120 received control signals in through the electrical connection 122 converted to transmitted control sequences. The from the rocker switch 100 generated first control signals are of the operating time of the rocker switch 100 dependent. These first control signals are via the electrical connection 120 transmitted to the control unit, which converts this first control signal into a pulse width modulated signal and the pulse width modulation module 118 with the help of the electrical connection 122 passes.

The pulse width modulation module 118 transform this via the electrical connection 122 received electrical signal in an analog voltage signal for the actuator 112 which via the electrical connection 124 to the actuator 112 is transmitted. The actuator moves according to this analog voltage signal 112 by means of a mechanical coupling 126 the window of the motor vehicle 114 ,

The position sensor 116 uses Hall sensors to determine the rotational speed as well as the rotational position of the actuator 112 and outputs this position or velocity in the form of electrical signals by means of the electrical connection 130 to the control unit 110 further. Has the position sensor 116 For example, it determines that the window 114 is in an end position, so the adjustment process by the control unit 110 immediately interrupted. The control unit 110 ensures that the window 114 only for the duration of the operation of the rocker switch 100 with a maximum available speed of the actuator 112 is moved.

In operation, the occupant can use the rocker switch 100 press around the window 114 to be adjusted with a maximum adjustment speed. As soon as the rocker switch 100 The user is no longer actuated, no control signals for the control unit 110 generated and consequently are no further control sequences for the actuator from the control unit 112 or control sequences for the pulse width modulation module 118 generated: The window 114 will thus stay in the position reached.

If the user presses the wheel 102 , this generates a second control signal, which consists of two mutually phase-shifted pulse trains, which by means of the electrical connection 120 to the control unit 110 be handed over. From the sign of the phase shift between the two control signals, the control unit 110 determine the desired adjustment direction.

Furthermore, it determines an intended adjustment path for the window from the number of incoming pulses. Furthermore, the control unit can determine an adjustment speed for the actuator from the frequency of the incoming pulse trains. Depending on one through the program module 140 to be set operating mode of the control unit 110 , that can be done in the control unit 110 received second control signal can be processed arbitrarily.

For example, the window 114 be moved with a minimum, constant adjustment speed. Here is the number of the rotary wheel 102 generated electrical impulses proportional to the intended adjustment of the window 114 ,

Furthermore, the speed with which the rotary wheel 102 is actuated. This speed, or the frequency of the electrical pulse train thus generated by the rotary wheel, the control unit 110 a certain adjustment speed of the window 114 assign.

Furthermore, depending on the position sensor 116 determined position of the window 114 a dynamic adjustment speed by the control unit 114 will be realized. Various adjustment angles and different adjustment speeds of the rotary wheel 102 can thus arbitrarily in different adjustment positions, adjustment speeds or adjustment functions of the window 114 be transmitted.

The from the rocker switch 100 generated first control signals have opposite those of the rotary knob 102 generated second control signals higher priority for the control unit 110 , Thus one can through the wheel 102 accidental actuation by the control unit 110 is interpreted as completely opening or closing the window by actuating the rocker switch 100 be stopped immediately. Despite various operating modes where the actuator 112 from an actuation time of the rotary wheel 102 is decoupled, the user can use the rocker switch 100 directly and immediately manually in the adjustment mechanism of the window 114 intervention.

2a shows a first diagram of control signals from the wheel 102 be generated. The angle of rotation of the rotary wheel is in this case horizontal and the amplitude of the control signals applied vertically. The vertical markings along the horizontal axis symbolize the individual locking positions of the rotary wheel. If the wheel is moved by the user in a clockwise direction, then a first signal 200 by half a detent position before a second signal 202 generated.

2 B shows the opposite case of a left-handed rotation of the wheel. In this case, the pulse sequence of the second signal takes place 202 by half a stop position before the pulse sequence of the first signal 200 , Due to the phase shift between the first signal 200 and the second signal 202 can the control unit 110 Determine the direction of rotation for the actuator.

3a shows a sketch of a possible embodiment of a multifunctional actuator 300 , The actuator 300 acts either as a rocker or tactile or snap-action switch. The rocker or tactile or snap-action switch 300 is here on a rocking axis 304 stored. By pressing or pulling the user at the switch 300 electrical contacts are closed or opened, so that a corresponding first control signal to the control unit 110 is transmitted. In the top of the switch 300 is a wheel 302 integrated, which upon rotation by the user second control signals to the control unit 110 transmitted.

3b shows a further embodiment of the multifunctional actuator 310 , This consists of two buttons 314 and 316 and a rotary wheel 312 , By pressing the button 316 is an upward movement of the window pane and by pressing the button 314 initiated a downward movement of the window. The wheel 312 is similar here as in 3a educated. The wheel 312 is endlessly rotatable and has equidistant locking positions. By incremental rotation, it generates the in 2a and 2 B sketched first and second signals 200 respectively. 202 in the control unit 110 be fed.

4 shows a flowchart which describes the generation and processing of control signals. The two steps 400 and 402 stand here in each case for the actuation of a first switch 400 or for the actuation of a second switch 402 ,

switch 1 corresponds to the aforementioned rocker or tactile or snap-action switch, which generates a control signal corresponding to its actuation time t. switch 2 corresponds here to the aforementioned rotary wheel, which generates a control signal, which consists of two different pulse sequences. This control signal indicates a rotation angle W and an adjustment speed of the rotary wheel V. The operation of the first switch 400 is one step 406 connected and the operation of the second switch 402 is with one step 408 connected. Both steps 406 and 408 be within the control unit 404 executed.

The steps 406 such as 408 calculate a specific pulse width modulation ratio, which in a further step 410 is transmitted to an analog voltage signal U (t). In a further step 412 the actuator is operated with the voltage signal U (t). Out of the step 400 determined time t is in step 406 calculates such a pulse width modulation ratio, so that the actuator in step 412 is operated with the maximum available voltage signal U-Max for a period of time t. In step 408 starting from the one in step 402 determined angle W and a determined adjustment speed V calculated a pulse width modulation ratio.

Furthermore, with the help of the pulse width modulation any fluctuations in the operating voltage of the actuator can be compensated. Such fluctuations in the operating voltage of the motor vehicle can occur especially under extreme external conditions. If the operating voltage of the motor vehicle drops or rises, then the pulse width modulation module can 118 as well as the control unit 110 , the drive sequences for the actuator 126 adjust accordingly, so that this independent of the operating voltage of the motor vehicle undergoes an unchanged control and the user does not notice any operating voltage differences.

According to the set operating mode of the control unit 404 a voltage signal U and a time t is calculated. In this case, U can assume a constant value over the time t, or U can be a function U (t) varying with time t. That in step 408 determined pulse width modulation ratio is in step 410 transformed into an analog voltage signal U (t) and finally in the step 412 passed on to the actuator.

5 shows a flowchart showing the generation of a control signal and its dynamic conversion into an actuating drive sequence. In step 500 a rotary switch according to the invention is moved by an angle W with an adjustment speed V2. The two parameters W and V2 are in a next step 504 used to calculate a desired position SP. The desired position SP is then passed to step 506 passed.

In step 506 the difference of this desired position SP is formed with an actual position of the actuator IP. If the difference between IP and SP exceeds a threshold in terms of amount, then step 510 continued. If the difference between IP and SP is less than the threshold SW, then step 508 continued.

In step 508 a constant adjustment speed is set for the actuator. In step 510 On the other hand, a dynamic adjustment speed is set for the actuator. After step 508 as well as after step 510 done step 514 , In step 514 is the pulse width modulation ratio starting from the in steps 508 or 510 certain speeds and in step 500 determined adjustment angle W. Furthermore, in step 514 an analog voltage signal U (t) is calculated for the time t. The voltage signal U (t) is for the period t in step 516 transmitted to the actuator. In step 518 Finally, the object to be adjusted with the calculated adjustment speed V and calculated time t is adjusted in a predetermined manner.

Going out from the step 516 outgoing adjustment will step in 512 the actual position of the actuator determined. In step 506 will the step out 512 determined actual position with the by step 504 given target position of the actuator compared. In step 506 For this purpose, in turn, the difference between the actual position IP and the desired position SP is determined. By comparing this difference with the predetermined threshold, the steps again become 508 or 510 initiated. The process continues in this manner until the process described in step 512 calculated actual position of the window IP with that in step 504 calculated target position SP matches. The steps 504 . 506 . 508 such as 510 find inside the control unit 502 instead of.

6a shows a diagram which describes a pulse width modulated signal. The corresponding analog voltage signal, however, is in 6b shown. Individual pulses of the pulse width modulated signal are with 600 . 602 . 604 . 606 and 608 designated. The pulse width modulated signal is further divided into seven time intervals with a width of t_0. The temporal length of a pulse compared to the time intervals determines the amplitude of the analog voltage signal.

The pulse 600 is for example as long as one of the time intervals. Consequently, the pulse becomes 600 for the duration of the first two time intervals in a voltage signal 610 interpreted at maximum amplitude. A temporally shortened pulse 602 is a correspondingly slightly lower amplitude 612 assigned. The same applies to the successively shortened pulses 604 . 606 and 608 , the successively decreasing voltage amplitudes 614 . 616 and 618 are assigned.
