Description
Vom Fahrgeschwindigkeitssensor 3 wird der Istwert der Fahrgeschwindigkeit des Fahrzeuges erfaßt und über einen Spannungs-/Frequenzwandler 5 und ein Filter 6 einem Sollwertspeicher 7 und einem Regelverstärker 8, der eine Soll-lstwert-Vergleichseinrichtung mit nachfolgendem Proportionalregler enthält, zugeführt. The actual value of the driving speed is obtained from the driving speed sensor 3 of the vehicle is detected and via a voltage / frequency converter 5 and a filter 6, a setpoint memory 7 and a control amplifier 8, which is a setpoint / actual value comparison device with the following proportional controller contains, supplied.
Das Verstellsignal des Regelverstärkers wird über einen Stellungsregler 9 dem Leistungsstellglied 4 zugeführt, dessen Rückmeldesignal über eine Leitung 10 dem Stellungsregler 9 zugeführt und von diesem verarbeitet wird. The adjustment signal of the control amplifier is sent via a positioner 9 fed to the power actuator 4, its feedback signal via a line 10 is fed to the positioner 9 and processed by it.
Außerdem ist noch eine Abschalteinrichtung 11 vorhanden, durch welche eine Abschaltung der Geschwindigkeitsregelung entweder durch den Bedienschalter 2, durch Betätigen des Kupplungs- oder Bremspedals 12 über einen von diesem betätigbaren Schalter 13 oder automatisch bei Unterschreiten einer vorgegebenen Geschwindigkeitsschwelle von z. B. 35 km/h. Für die automatische Abschaltung ist in der Abschalteinrichtung 11 ein Schwellwertgeber mit einer der vorgegebenen Mindestgeschwindigkeit entsprechenden Schwelle vorgesehen. In addition, there is also a disconnection device 11 through which a shutdown of the cruise control either by the control switch 2, by actuating the clutch or brake pedal 12 via one that can be actuated by this Switch 13 or automatically when falling below a predetermined speed threshold from Z. B. 35 km / h. For the automatic shutdown is in the shutdown device 11 a threshold value transmitter with a corresponding to the predetermined minimum speed Threshold provided.
Die Geschwindigkeitsregeleinrichtung hat die Aufgabe, die Geschwindigkeit des Fahrzeuges entsprechend dem gespeicherten Sollwert konstant zu halten. The speed control device has the task of controlling the speed of the vehicle to keep constant according to the stored target value.
F i g. 2 zeigt eine schematische Darstellung der in die bekannte Geschwindigkeitsregeleinrichtung integrierten erfindungsgemäßen Schaltung. F i g. FIG. 2 shows a schematic representation of the known in FIG Speed control device integrated circuit according to the invention.
Elemente aus F i g. 1 sind nur soweit dargestellt, wie sie zum Verständnis der Schaltung erforderlich sind. Sie tragen die Bezugszeichen wie in F i g. 1. Auf eine nochmalige Beschreibung kann deshalb verzichtet werden. Elements from FIG. 1 are only shown to the extent that they are for understanding the circuit are required. They have the same reference numbers as in FIG. 1. On a repeated description can therefore be dispensed with.
Die Zuordnung der Einzelelemente zueinander ist gegenüber der in F i g. 1 geändert, um die Funktion der erfindungsgemäßen Schaltungsergänzung besser darstellen zu können.The assignment of the individual elements to one another is different from that in F i g. 1 changed to improve the function of the circuit addition according to the invention to be able to represent.
Neben dem Bedienschalter 2 ist ein manuell betätigbarer Schalter 14 dargestellt, welcher auch als weitere Schaltstellung in den Bedienschalter 2 integriert sein kann. Von diesem Schalter 14 werden drei Umschalter S 1, S2 und S3 betätigt. In addition to the control switch 2 is a manually operated switch 14, which can also be used as a further switch position in control switch 2 can be integrated. From this switch 14, three changeover switches S 1, S2 and S3 actuated.
Der erste Umschalter S ist in die Verbindung vom Sollwertspeicher 7 zum Sollwerteingang des Regelverstärkers 8 eingefügt. In der gezeichneten Stellung der Schalter S1, S2 und S3 - der Ruhestellung - gewährleisten diese den Betrieb der Geschwindigkeitsregeleinrichtung in der bisher bekannten, oben beschriebenen Art und Weise. Über den Umschalter S 1 gelangt der erst Fahrgeschwindigkeits-Sollwert vom Sollwertspeicher 7 zur Soll-lstwert-Vergleichseinrichtung des Regelverstärkers. Nach Umschalten des Schalters 14 in die Arbeitsstellung gelangt ein zweiter Fahrgeschwindigkeits-Sollwert an die Soll-Istwert-Vergleichseinrichtung, welcher in diesem schematischen Beispiel über ein an einem Pol der Bordspannung B liegendes Patentiometer abgreifbar und in gewissen Grenzen verstellbar sein kann, zum Beispiel im Bereich von 30+5 km/h. The first switch S is in the connection from the setpoint memory 7 added to the setpoint input of control amplifier 8. In the position shown the switches S1, S2 and S3 - the rest position - ensure this operation the speed control device in the previously known, described above Way. The first driving speed setpoint is reached via switch S 1 from the setpoint memory 7 to the setpoint / actual value comparison device of the control amplifier. After switching the switch 14 to the working position, a second travel speed setpoint value is reached to the setpoint / actual value comparison device, which in this schematic example can be tapped via a patentiometer located at one pole of the on-board voltage B and can be adjustable within certain limits, for example in the range of 30 + 5 km / h.
Dieser Sollwert kann mittels einer über den vom Bremspedal 12 betätigbaren Schalter 13 aktivierbaren Stelleinrichtung 15 weiter herabgesetzt werden. Dies geschieht über die Arbeitsstellung des Umschalters S2.This setpoint value can be actuated by means of the brake pedal 12 Switch 13 activatable control device 15 can be further reduced. this happens about the working position of the switch S2.
Die Arbeitsweise der Stelleinrichtung 15 ist nicht näher ausgeführt. Diese kann beispielsweise als Motorpotentiometer ausgeführt sein, welches bei geschlossenem Bremspedalschalter 13, der einseitig je nach Schaltung am Plus- oder Minuspol der Bordspannung B liegt, mit einer einer bestimmten Fahrzeugverzögerung entsprechenden Geschwindigkeit den zweiten Fahrgeschwindigkeits-Sollwert herabsetzt - bei automatischem Getriebe bis zum Stillstand möglich - und bei geöffnetem Bremspedalschalter 13 wieder bis zum maximalen Wert erhöht, sie kann aber auch abhängig vom Bremsdruck oder mit vom Bremsdruck variierbarer Geschwindigkeit des Motorpotentiometers arbeiten. In Ruhestellung des Umschalters S2 bleibt die ursprüngliche Funktion des Bremspedalschalters 13, bei Betätigen des Bremspedals ein Signal an die Abschalteinrichtung 11 zum Abschalten der Geschwindigkeitsregelung zu liefern, erhalten.The mode of operation of the actuating device 15 is not detailed. This can be designed, for example, as a motor potentiometer, which is closed when the Brake pedal switch 13, the one-sided depending on the circuit on the plus or minus pole of the On-board voltage B is, with a corresponding to a certain vehicle deceleration Speed reduces the second travel speed setpoint - with automatic Transmission possible down to a standstill - and again when the brake pedal switch 13 is open increased up to the maximum value, but it can also be dependent on the brake pressure or with the speed of the motor potentiometer, which can be varied by the brake pressure. In The rest position of the switch S2 remains the original function of the brake pedal switch 13, when the brake pedal is actuated, a signal is sent to the disconnection device 11 for disconnection to deliver the cruise control.
Mit dem Umschalter S 3, der in Ruhestellung das Ausgangssignal des Schwellwertgebers 11 a, welches beim Unterschreiten der vorgegebenen Mindestgeschwindigkeit von z. B. 35 km/h erscheint, innerhalb der Abschalteinrichtung 11 weiterverarbeitet, wird in Arbeitsstellung dieses Abschaltsignal unterbunden, sodaß die Geschwindigkeitsregeleinrichtung auch unterhalb der im normalen Geschwindigkeitsregelbereich wirksamen Mindestgeschwindigkeit arbeiten kann. With the switch S 3, which in the rest position the output signal of the Threshold transducer 11 a, which when falling below the predetermined minimum speed from Z. B. 35 km / h appears, further processed within the cut-off device 11, this switch-off signal is suppressed in the working position, so that the speed control device also below the minimum speed effective in the normal speed control range can work.
Der Betrieb der auf diese Weise veränderten Geschwindigkeitsregeleinrichtung gestaltet sich für den Fahrer recht einfach. Bei sonst unveränderter Betriebsweise muß der Fahrer in Zonen, wo nur geringe Fahrgeschwindigkeiten erlaubt bzw. möglich sind, z. B. in Wohngebieten, aber auch bei Verkehrsstau u.s.w., lediglich den Schalter 14 in Arbeitsposition bringen. Das Fahrzeug verzögert oder beschleunigt dann automatisch, bis die durch den zweiten Fahrgeschwindigkeitssollwert bestimmte Geschwindigkeit erreicht ist. Diesen Sollwert kann der Fahrer in gewissen Grenzen manuell verändern, um die Geschwindigkeit seines Fahrzeuges dem Verkehrsfluß anpassen zu können. Diese automatisch eingeregelte Geschwindigkeit kann er durch Betätigen des Bremspedals kontinuierlich verringern - bei Fahrzeugen mit handgeschalteten Getrieben in gewissen Grenzen je nach eingelegtem Gang, bei Fahrzeugen mit automatischen Getrieben bis zum Fahrzeugstillstand - und durch Loslassen des Bremspedals wieder bis zum Sollwert erhöhen. Eine weitere Erhöhung der Geschwindigkeit kann mittels des Fahrpedals, wie bei der Geschwindigkeitsregeleinrichtung bekannt, erfolgen. The operation of the cruise control device modified in this way is quite easy for the driver. With otherwise unchanged operating mode the driver has to work in zones where only low driving speeds are permitted or possible are e.g. B. in residential areas, but also in traffic jams, etc., just press the switch Bring 14 into working position. The vehicle then decelerates or accelerates automatically, until the speed determined by the second travel speed setpoint is reached. The driver can change this setpoint manually within certain limits, in order to be able to adapt the speed of his vehicle to the traffic flow. These he can set the speed automatically by pressing the brake pedal continuously decrease - in certain vehicles with manual transmissions Limits depending on the gear engaged, for vehicles with automatic transmissions up to to the vehicle standstill - and by releasing the brake pedal back to the target value raise. The speed can be increased further using the accelerator pedal, as known from the speed control device.
