Definitions
- the present invention relates to a steering unit for a motor vehicle and a method for its operation.
- a steering unit for a motor vehicle is known from DE 10 2009 021 280 A1, in which a touchpad control for various functions of the motor vehicle is installed in a steering wheel on its hub.
- the touchpad includes one
- DE 10 2009 021 280 A1 provides for the touchscreen to be deactivated when a predetermined steering wheel angle is exceeded.
- the object of the present invention is to provide a steering unit for a motor vehicle, in which a safe and simple reading of a screen integrated into the steering wheel is guaranteed, regardless of its steering angle.
- the object is achieved in that, in a steering unit for a motor vehicle with a steering wheel having an integrated screen and a control unit for controlling the output of at least one first image on the screen, the control unit is set up to rotate the image counter to a rotation of the steering wheel. So is related to the perspective of a driver who is on the
- the steering wheel comprises an outer ring and at least one spoke connecting the outer ring to a hub, then the spoke most likely offers space for the screen.
- Placing the screen close to the axis of rotation also has the advantage that the direction from which the image is presented to the driver changes only slightly when the steering wheel is turned. In order to minimize the distance from the axis of rotation, it is preferred that an axis of rotation of the steering wheel crosses the screen.
- the screen can extend symmetrically over two spokes that run in mirror image to one another between the hub and the outer ring.
- the axis of rotation of the steering wheel can coincide with an image axis about which the control unit rotates the image;
- the control unit is preferably set up to rotate the first image about a first point offset against an axis of rotation of the steering wheel.
- This first point should be within the first image; it is preferably a center of the first image.
- the screen In order to take advantage of the installation space available on the steering wheel, in particular on its spoke, the screen must be elongated; however, they are
- Control unit can be set up to rotate a second image around a second point offset from the first point. This second point should also be located within the second image and preferably represent a center of the image.
- the second point should be stationary with respect to the steering wheel, i.e. rotate the steering wheel around the axis of rotation on a circular path concentric to the axis of rotation.
- control unit In order to detect an angle of rotation of the steering wheel relative to a neutral position, the control unit can be connected to an angle of rotation sensor which detects the steering angle of the steering wheel.
- control unit can be connected to an acceleration sensor in order to detect the direction of an acceleration acting on the steering wheel and to keep the orientation of the image constant relative to the vector of the acceleration. This can lead to the fact that the orientation of the image deviates from the orientation when driving straight ahead when cornering.
- the control unit can also be set up to switch between different contents of at least the first image on the basis of a control input.
- a first image adjacent to the axis of rotation can show a manufacturer logo, as is conventionally applied as an embossing or as a separate component in the center of a steering wheel; if necessary, however, the logo, which is only displayed as an image on the screen, can be replaced by any other temporarily relevant information, in particular warnings.
- the invention further relates to a method for operating a steering wheel with an integrated screen, in particular a steering wheel as described above, with the steps:
- Figure 1 is a plan view of a steering wheel with a screen and an image displayed on the screen in the neutral position.
- FIG. 2 is a top view of the steering wheel of FIG. 1 in an engaged position
- Fig. 3 is a plan view of the steering wheel with two on the
- FIG. 4 is a top view of the steering wheel of FIG. 3 in a turned position
- Fig. 5 shows a schematic section through the steering wheel.
- the steering wheel 1 shows a steering wheel 1 of a steering unit according to the invention in a plan view along an axis of rotation 2, about which the steering wheel 1 is rotatably mounted in a motor vehicle (not shown).
- the steering wheel 1 usually comprises an outer ring 3, and at least one spoke 4, which extends radially inward from the ring 3 to a hub 5.
- spokes 4 In the case considered here there are three spokes 4 provided, two of which are diametrically opposite on different sides of the hub 5, so that a screen 6 can extend straight across the hub 5 from one spoke 4 to the other.
- An LCD display with a large viewing angle or an OLED display can be considered as the screen 6.
- the screen 6 is surrounded all around by a frame 7, the color of which is matched to the color of a black-indicating pixel of the LCD display or a switched-off pixel of the OLED display, so that the screen 6 is not immediately recognizable as such.
- An electronic control unit 8 which determines the color and brightness value of each pixel of the screen 6, can be integrated into the steering wheel 1, e.g. 5, be provided on a printed circuit board 9 arranged in one of the spokes 4 behind the screen 6; but it can also be physically separated from the steering wheel 1, e.g. Part of an on-board computer of the vehicle can be connected to the screen via a data line running through the steering column.
- control unit 8 is connected to an angle encoder 10, which is fixedly mounted in the steering wheel 1, by the steering angle of the
- Steering wheel 1 to detect a non-rotating reference point of the steering column.
- an angle encoder which
- steering angle data for the control of the steerable wheels of the vehicle can also be used to supply the control unit 8 with steering angle data.
- the angle encoder 10 could be on the steering wheel 1, e.g. on the circuit board 9, an acceleration sensor to be mounted to detect the direction of gravity relative to the steering wheel and from it
- FIG. 1 In the view of Fig. 1, the steering wheel 1 is in a neutral position corresponding to straight travel, i.e. the turning angle is zero.
- An image 11 generated by the control unit 8 in the middle of the screen 6 shows a
- the axis of rotation 2 crosses the displayed image 11.
- a center 13 of the image 11 is slightly offset from the axis of rotation 2.
- the control unit 8 determines a current steering angle f of the steering wheel 1 and rotates the image 11 relative to the one shown in FIG.
- the content of image 1 1 is variable. It can therefore be used to convey information to the driver.
- the electronic control unit 8 is connected to a satellite navigation system or a
- Driver assistance system coupled - by comparing the current
- Driver assistance system receives an indication of a route ban or a danger, it shows a representative traffic sign 15 instead of the
- the position of the center 13 can also vary; In the case shown here, the center 13 of the manufacturer symbol 12 is just above that of the warning triangle 15 just below the axis of rotation 2.
- Fig. 3 shows a view of the steering wheel 1, in which the traffic sign 15 is a general hazard warning. If the satellite navigation or
- the driver assistance system can provide correspondingly precise hazard warnings, but can also be a more specific warning, for example a warning of an intersection with a privileged crossing or a right-to-left priority regulation or a warning of a curve ahead; in general, any hazard warning signs that appear in the country of use of the Vehicle's current road traffic regulations can be set up on a street, also shown in Figure 11.
- a route ban such as a speed limit or an overtaking ban
- the image 11 does not rotate with the steering wheel 1, since reading the displayed digits requires increased concentration if they are displayed rotated by arbitrary angles rather than in the usual orientation.
- the image 11 can also be used to transmit information relating to the operation of the vehicle to the driver by showing corresponding image content, e.g. to clearly indicate a low level of a fuel tank, lack of oil, the need for maintenance or the like.
- the picture 1 1 can be used to provide information about the call, such as the name and / or number of the call.
- Areas 16 (see FIG. 1) of the screen 6 that are distant from the steering axis 2 can be used to display images there that are not rotated in opposite directions to the steering wheel rotation by the control unit 8. This is especially true for pictures with edge length ratio deviating strongly from 1, for example for the representation of a scale, makes sense. But it is also conceivable to use images such as 17 (see
- Fig. 3, 4 preferably with an edge length ratio close to 1, which are rotated in the event of a rotation of the steering wheel 1 by the control unit 8 about its own center 18, so that when the steering wheel 1 rotates with it around the Rotate axis of rotation 2, but like the picture 1 1 their
- Figure 17 shows an example of a coffee cup asking a driver to take a break to alert the attention monitoring assistant
