Abstract

The unit has an accelerator pedal guidance (1), which permits straight line movement of the accelerator pedal in a driving direction. The accelerator pedal (2) is rotated for linear movement such that the driving direction is predetermined, where the accelerator pedal parameters are adapted to the emergency situation. An emergency signal (4) is released at an accelerator pedal handle (3), where the signal is an acoustic or optical signal.

Description

Die Erfindung betrifft Bediengeräte für Sonderfahrzeuge, bei denen spezielle Anforderungen an die Einfachheit und Robustheit der Steuerung für den Fahrbetrieb bestehen.The Invention relates to HMI devices for special vehicles, where special requirements for simplicity and robustness the controller for the driving operation exist.

Für die Steuerung derartiger Fahrzeuge kommt ausschließlich der sogenannte „Joystick" in Verbindung mit Folientastaturen zum Einsatz. Im Fahrmodus sind entsprechend der Richtung der Auslenkung des Joysticks die Funktionen vorwärts-rückwärts und links-rechts zugeordnet. Dabei erfordert die Stiftmechanik eine feinfühlige Bedienung, weil der Stiftknopf nach allen Richtungen leicht beweglich ist. Das ist beim schnellen Fahren über Unebenheiten problematisch.For the controller Such vehicles comes exclusively with the so-called "joystick" in connection with Membrane keyboards are used. In driving mode are according to the Direction of the deflection of the joystick the functions forward-backward and assigned to left-right. The pen mechanism requires a sensitive Operation, because the pin button is easily movable in all directions. That's over during fast driving Bumps problematic.

Aber auch die Anforderungen an die Fahrtüchtigkeit schränken die Benutzung von Elektrofahrzeugen durch Menschen mit körperlichen Beeinträchtigungen (z.B. Tremorerkrankungen) von vornherein ein. ( DE 000000901263 B )But the requirements for the ability to drive restrict the use of electric vehicles by people with physical impairments (eg, tremor diseases) from the outset. ( DE 000000901263 B )

Die Erfindung hat die eindeutige Trennung in der Aktivierung der Fahrfunktionen durch grundverschiedene Bewegungsarten des Fahrhebels zum Ziel. Dabei sind in der Zuordnung der Fahrparameter die bei Fahrzeugen allgemein üblichen Bewegungsabläufe anzustreben und die Einhebelbedienung beizubehalten.The Invention has the clear separation in the activation of the driving functions by fundamentally different types of movement of the driving lever to the destination. Here are the assignment of the driving parameters in vehicles generally accepted movements to strive for and to maintain the one-lever operation.

Die erfindungsgemäße Lösung beinhaltet die Nutzung zusätzlicher Freiheitsgrade in den Bewegungsmöglichkeiten des Fahrhebels.The inventive solution includes the use of additional Degrees of freedom in the possibilities of movement of the driving lever.

Die Nullstellung des Fahrhebels bedeutet Fahrzeugstillstand. Seine Bewegung nach vorn die Vorwärtsfahrt mit einer Geschwindigkeit, die von der Größe der Auslenkung abhängig ist.The Zeroing the driving lever means vehicle standstill. His movement forward the forward drive at a speed that depends on the magnitude of the deflection.

Der Fahrhebel ist bei seiner Vorwärtsbewegung zwangsgeführt und in seiner Funktion als Geschwindigkeitssteller eindeutig logisch („Gashebel"). Seitliche Krafteinwirkungen bleiben damit völlig folgenlos. Die Rückwärtsfahrt setzt einen Schaltvorgang voraus und kann damit nicht unbeabsichtigt erfolgen.Of the Driving lever is in its forward movement forced out and in its function as a speed knob clearly logical ("Throttle") stay with it completely without consequences. The reverse drive requires a switching operation and can not be unintentional respectively.

Eine Änderung der Fahrtrichtung wird ausschließlich durch eine entsprechende Drehbewegung des Fahrhebels bewirkt (analog dem Lenkrad), wobei mit einer Vergrößerung des Drehwinkels eine stärkere Richtungsänderung erfolgt. Gleichzeitig wird automatisch durch einen Schaltvorgang der jeweilige Fahrtrichtungsanzeiger aktiviert, der, ebenfalls durch die Drehbewegung ausgelöst, beim Zurückdrehen in die Geradeausstellung wieder abschaltet.A change the direction of travel is exclusively by an appropriate Rotary movement of the driving lever causes (analogous to the steering wheel), wherein with an enlargement of the Angle of rotation a stronger one change of direction he follows. At the same time is automatically by a switching operation the respective direction indicator is activated, which, also by the Rotational movement triggered when turning back switches off again in the straight ahead position.

Die Hebelweglängen und Drehwinkel können individuell angepasst werden.The Hebelweglängen and angle of rotation can be customized.

Zur besseren Handhabung ist das Fahrhebelende als ergonomisch ausgebildeter Griff ausgeführt, der auch durch besondere Formgebung den Bedürfnissen des Nutzers anzupassen ist.to better handling is the end of the drive lever as ergonomically designed Handle executed, which can also be adapted to the needs of the user by special design is.

In der Griffmitte, etwas versenkt, ist ein Taster (4) für die Alarmblinkanlage vorgesehen. Damit kann der Fahrer leicht eine Notsituation, die Hilfe erforderlich macht, signalisieren.In the middle of the handle, a bit sunk, is a button ( 4 ) provided for the alarm flashers. Thus, the driver can easily signal an emergency situation that requires help.

Zusätzlich zur federbewirkten Rückführung des Fahrhebels (2) in die Nullstellung kann zur Erhöhung der Sicherheit der Fahrhebelgriff (3) mit Sensoren ausgestattet werden, die die Fahrfunktionen nur bei unmittelbaren Handkontakt aktivieren.In addition to the spring-driven feedback of the driving lever ( 2 ) in the zero position can increase the safety of the lever handle ( 3 ) are equipped with sensors that activate the driving functions only with direct hand contact.

Die neu entwickelte Bedieneinheit stellt eine deutliche Erleichterung beim Steuern von Sonderfahrzeugen dar, weil sie allgemein übliche Bewegungsabläufe beim Führen von Fahrzeugen als Grundlage hat, mit nur einem Bedienhebel die klare Unterscheidung der Vorgabe von Fahrtrichtung und Fahrgeschwindigkeit durch wesensverschiedene Bewegungsformen ermöglicht und geringe Anforderungen an die Feinmotorik des Nutzen voraussetzt.The newly developed control unit makes a significant relief when controlling special vehicles, because they are common in the movement sequences To lead of vehicles as a basis, with only one operating lever the clear distinction between the specification of direction of travel and driving speed made possible by essentially different forms of movement and low requirements to the fine motor skills of the benefit presupposes.

Mit dem innovativen Konzept wurde ein Rollstuhl mit Elektroantrieb ausgestattet.With The innovative concept was equipped with a wheelchair with electric drive.
