- Actuator may be arranged in an electrical and / or electronic switch in the manner of a joystick or cursor switch.
- the device has electric motors which are connected to the selector lever.
- the devices of the prior art have the disadvantage that their structure is very complex and a variety of components is required to realize the individual sub-functions.
- the simply constructed devices are limited in their functional scope.
- the invention has for its object to provide an improved device for selecting driving levels, which allows over the prior art, a more reliable switching between individual driving levels. This object is achieved by a device for selecting driving steps
- control element which is designed to be manually pivotable or rotatable with respect to at least one axis of rotation, wherein by means of an actuator acting on the actuator haptic feedback to a user can be generated. Furthermore, a, depending on the position of the control element, the actuator-actuating and speed control signals generating control is provided.
- the invention is particularly characterized by the fact that the different speed levels
- the invention relates, for example, to a control element which is movable in the X and / or Y direction, for example in the manner of a rotary knob or joystick, whose force feedback can be freely programmed.
- the torque or the force of the operating element is applied by at least one actuator.
- this system allows the shift travel and force to be adjusted according to the individual wishes of the manufacturer or the driver. This is how it works with the same system
- Rastier device also new functions, for example Rastier product can be changed depending on the condition or alarmed in unauthorized switching states of the driver by means of feedback.
- control element can automatically be tracked during autonomous driving of the gear position.
- the control element in addition to the manual operation by the user for an automatic
- Switching be formed by the actuated by the control actuator.
- An actuator in the context of the present invention is a drive element which can convert a control signal into a mechanical movement or act as a brake.
- the device according to the invention has the advantage that even with a not triggered by the user driving level change, for example, when autonomous
- Driving operation in an automatic operation of the transmission, in an automated application of the parking brake or a shift paddle engagement, which corresponds to the user visible and / or tactile position of the control element of the currently engaged gear.
- the control of the device receives from a further control device of the vehicle, a signal which contains the information about the currently engaged gear, for example, from the transmission control unit or responsible for autonomous driving, the shift paddles or the parking brake control unit.
- the controller adjusts the information about the currently engaged drive level with the currently present position of the operating element.
- the control actuates the actuator in order to transfer the operating element into the predetermined driving position, hereinafter referred to as switching position.
- a return of the control element from a newly selected by the user switching position in the current driving position corresponding switching position when switching to the selected by the user switching position corresponding drive level is not done. If the user, for example, in a simulated H-shift the control from the switch position for the gearbox "forward gear 3" in the switching position for the gearbox “forward gear 2" leads, although such a gear stage change due to impending overspeed does not occur, the controller Activate actuators that the control outputs a haptic feedback for the duration of manual user intervention. As soon as the user releases the operating element by releasing it, this is due to the then automatically executed switching movement active and directed back to the current driving position corresponding switching position, in the present example, the switching position "forward speed 2".
- the control automatically returns to a user-made, manual deflection in the stable rest position, when the feel of a conventional monostable circuit diagram and thereby acting on the control restoring forces through the
- Actuators are modeled. An automatic switching movement in a monostable shift pattern takes place when in the motor vehicle or in the transmission of a speed level change without user intervention on the operating element of the device and the monostable control element undergoes an automatic movement from its rest position to the
- the different driving levels are assigned different switching positions of the control element, wherein the switching thresholds of adjacent switching positions are spaced from each other. In this way, it is achieved that the operating element can be moved out of the switching position up to a predetermined limit without the switching stages being switched over. This is particularly advantageous if the user, for example, an inaccurate or unintentional input to the
- At least one position sensor for determining the pivoting or rotational position of the operating element relative to the at least one axis of rotation and for generating a corresponding position signal may be provided.
- the position sensor detects either permanently, in a predetermined time
- Position sensor an analog or digital position signal, which is further processed by the controller connected to the position sensor.
- the position sensor can determine either the pivoting or rotational position of the operating element based on the at least one rotational position of the operating element. It is also conceivable that the position sensor additionally detects the position with respect to a second axis of rotation and transmitted to the controller. In a variant of the invention, the position sensor can be arranged directly on or on the axis of rotation.
- axis of rotation can be understood to mean an axle component or a shaft which is designed to mount the operating element on the device in a rotatable or pivotable manner.
- a rotation axis can also be a virtual axis around which the operating element By means of a bearing, it is possible to rotate or swivel the position of the position sensor
- Control element are determined very accurately.
- the position sensor can be arranged on the actuator in order to evaluate the movement generated by the latter and to conclude therefrom based on the position of the operating element.
- an additional gear may be provided on the actuator, which overshoots or underpins the motion generated directly by the actuator. For example, a rotational movement of the actuator to increase the measurement resolution can be translated so that a generated by the actuator
- Rotation is multiplied for the purpose of position measurement. This is particularly suitable for relative measurement methods, in which the sensors are not limited in their rotation angle. A reduction of the movement generated by the actuator is useful when an absolute measuring method is used, in which the sensor is movable only over a limited angle or a limited distance.
- control can be designed both for determining a switching position of the operating element as well as for generating a control signal for the movement and / or the haptic feedback of the control element including the position signal of the position sensor.
- the switching position is a position of the operating element, which after the current
- the used circuit diagram corresponds to a specific speed level or a certain speed step change.
- the device can be simplified so that with little metrological effort several functions of the device can be performed simultaneously. For example, it is possible to dispense with a separate sensor system for determining the engaged driving position or a special sensor system for generating the haptic.
- the at least one actuator may be designed as an electric motor, for example as a DC motor.
- BLDC motors are particularly preferred.
- BLDC stands for "Brushless Direct Current”.
- Such motors are characterized by the fact that they have a permanent magnet armature, which is surrounded by fixed stator coils, which are operated with direct current.
- a so-called “commutation” of the direct current is required, ie the controlled or regulated wiring of the stator coils with direct current in a predetermined clocking
- the timing depends on the rotational position of the armature within the motor as well as the desired amount of movement or force to be generated at the anchor BLDC motors are also particularly well suited for Generation of a torque in the engine. It has been shown that this type of motor is therefore particularly well suited for generating virtual detents, virtual stops, virtual mechanical resistance, virtual tours and virtual scenes.
- the actuator is designed as a BLDC motor and the control is designed to generate a commutation signal for the BLDC motor, including the position signal of the position sensor.
- the position sensor of the position sensor can even be used in three ways, so that a separate sensor for detecting the armature position of the BLDC motor for the purpose of commutation can be omitted.
- the invention may further provide that the operating element is connected to the axis of rotation.
- the structure of the device can be simplified, since consuming storage is largely dispensed with.
- such a configuration is suitable for devices with only one axis of rotation, such as rotary Fahrkinn flirtlvorraumen.
- the haptic feedback in the device can at least "force feedback", ie the generation of a counterforce for manual user input, and / or vibration and / or at least one virtual end stop and / or a virtual lateral guidance and / or a virtual slotted guide and / or
- a conventional, mechanical circuit can be simulated realistically, whereby the user inputs by adjusting the operating element only affect the actual driving position of the vehicle, if at the same time certain safety criteria are met
- the device can immediately report this back to the user by means of the haptic feedback. For example, at too high a speed for a
- Speed change a vibration can be output via the control to notify the user that the desired speed change is not possible or prevented for safety reasons.
- the generation of a virtual end stop makes it possible to prevent the user from inserting a specific switching position, thus informing him that the desired switching does not take place.
- Virtual side guides and virtual gate guides make it possible to provide the user with different circuit diagrams available, for example, a H-circuit link or a monostable control element, which automatically returns to a rest position after selecting a switch position.
- An emulated one for example, a H-circuit link or a monostable control element, which automatically returns to a rest position after selecting a switch position.
- Rastians gives the user haptic feedback about the actual position of the control, so that a desired selection of a gear can also be blind.
- the vibration takes place around at least one axis of rotation of the device.
- the amplitude of the vibration is generated at a provided for the user interface of the control element and thereby covers a
- this arc length is in the range of about 0.2 mm to about 0.5 mm, in particular about 0.3 mm.
- the vibration frequency of such a vibration may preferably be between 5 Hz and 100 Hz, preferably between 20 Hz and 30 Hz. It has been found that vibrations with the above-mentioned parameters are particularly noticeable by the human hand and thereby sufficiently different from the other in a moving or running vehicle typically prevailing vibrations, so that the vibration feedback is not or rarely with another in the Vehicle occurring vibration is confused.
- control element can be designed either as a selector lever and / or as a rotary knob.
- Selector levers mimic the well-known from conventional vehicles devices, such as shifter, for selecting driving levels particularly well, so that a habituation of the user is hardly required.
- Knobs can on the other hand, can be accommodated in a dashboard of a vehicle in a particularly space-saving manner.
- the operating element can be designed as a selector lever, which is pivotable or rotatable about two axes of rotation, the axes of rotation being substantially perpendicular to one another, preferably intersecting substantially perpendicularly.
- the selector lever can be moved in two spatial directions and thus take a variety of different positions, so that two-dimensional circuit diagrams such as an H-circuit or an automatic scheme with a separate jogging track can be modeled.
- each axis of rotation is associated with only one actuator, so that all functions for exerting a force on the
- Operating element are united around the respective axis to an actuator. This simplifies the construction of the device, making it easier to control and also
- the actuator of a rotational axis in response to the position of the operating element with respect to the other axis of rotation and / or the actuator of the other axis of rotation in dependence on the position of the control element with respect to a rotational axis is controlled.
- it is particularly easy to generate virtual lateral guides and / or virtual scenes and / or virtual detents.
- the overlapping of the driving step ranges of adjacent switching positions is approximately VA to V2, preferably 3 / s, of the width of a driving step range. This is a particularly good compromise between the maximum deflection of the
- the device may have a sensor connected to the controller, for example a touch sensor, which detects a manual intervention of the user and outputs a corresponding signal to the controller. This allows the detection of additional information as to whether the user is grasping the control. On the basis of this information can already be switched to a manual switching mode even before a
- the invention has the further object of providing an improved method for selecting driving levels, which allows a more reliable switching between individual driving levels compared to the prior art.
- This task is accompanied by a method for selecting driving steps
- Device carried out and is characterized in that the different driving levels are assigned different switching thresholds of the control element for switching to another gear and the control triggers a speed level change as soon as a switching threshold is exceeded in the direction of its associated switching position , This way will
- Control element initiated adjusting is opposite.
- the force feedback can signal the user, on the one hand, the achievement of a virtual end position at a virtual end stop.
- a virtual detent by means of the restoring force can be generated by the restoring force is modulated so larger or smaller, that the user creates the haptic impression, the control moves over a mechanical detent with several monostable breakpoints.
- Resetting force can be adjusted so that it is also stronger with increasing deflection of the control.
- the function of a mechanical return spring can be simulated, which deforms according to Hooke's law.
- a combination of these subfunctions is also possible. For example, a monostable
- Operating element are simulated with an approximately linearly increasing restoring force, which is also superimposed with a virtual detent.
- the restoring force is dependent on the position of the operating element.
- both the amount and the direction of the return force can be controlled or regulated position-dependent.
- the restoring force increases with increasing deflection of the operating element.
- the Nachempfindung a detent as a virtual detent the Nachempfindung a longitudinal guide as virtual longitudinal guidance or Nachempfindung a backdrop as a virtual backdrop amount and direction of the restoring force position dependent controlled or regulated so that the control element at a certain position or in a certain position range despite exercise of an adjusting the user remains.
- the actuator depending on the position of the operating element vibration of the operating element to the at least one
- Rotary axis or one of the axes of rotation causes. This makes it possible, in addition to the haptic feedback by a restoring force, an additional haptic signal to be generated by which the user can be informed about a particular state of his vehicle. So it is possible, for example, that
- the actuator moves the operating element in a predetermined position.
- the procedure has the im
- Operating element is formed in addition to the manual operation by the user for an automatic switching movement by the actuated by the controller actuator.
- the predetermined position corresponds to a drive level or to a drive level change, in particular to an automatically engaged or predefined drive level.
