BRIEF DESCRIPTION OF THE DRAWINGS

[0028] FIG. 1 shows a schematic representation of a vehicle, comprising an assistance system according to the invention and a navigation system, and

[0029] FIGS. 2a-2d show a schematic representation of individual snapshots of the animated representation of prepared route data while driving on a curve located in front of the vehicle.

DETAILED DESCRIPTION OF THE DRAWINGS

[0030] In the figures, identical or functionally identical elements are provided with the same reference signs.

[0031] FIG. 1 shows a schematic representation of a vehicle 1. The vehicle 1 comprises an assistance system 2. The assistance system 2 comprises here a computing device 3, a computer-readable (storage) medium 4, and a display device 5. Furthermore, the vehicle 1 comprises a navigation system 6.

[0032] The computing device 3 of the assistance system 2 can be configured to carry out a method for assisting a driver of the vehicle 1 when driving on a predetermined route course in road traffic. The navigation system 6 can provide prepared route data to the computing device 3 of the assistance system 2. The prepared route data can be displayed in an animated manner by means of the display device 5 of the assistance system 2. The display device 5 can be designed here as a so-called augmented reality head-up display (AR-HUD). Such a head-up display enables the prepared route data to be displayed in an animated manner within an augmented reality.

[0033] A curve 13 of the predetermined route course located in front of the vehicle 1 can thus be announced by means of the display device 5. The announcement of the curve 13 located in front of the vehicle 1 can be announced here by means of a docked display element 7 and an announcing display element 8. The docked display element 7 and the announcing display element 8 can be projected onto a windshield of the vehicle 1, so that the docked display element 7 and the announcing display element 8 are displayed above the roadway 9 for the driver of the vehicle 1. The impression thus arises for the driver of the vehicle 1 that the docked display element 7 and the announcing display element 8 are part of the surroundings 10 of the vehicle 1.

[0034] Such an animated display of prepared route data within an augmented reality by means of a head-up display enables a fluid and safe way of driving. Moreover, the driver of the vehicle 1 does not have to look away from the roadway 9 and look toward a display in the interior of the vehicle 1 in order to obtain items of information on the route course located in front of the driver. Furthermore, the driver feels safer. The impression can thus be conveyed to the driver of the vehicle 1 as if the driver already knew the route course located in front of the driver and in particular the curve 13 located in front of the vehicle 1.

[0035] FIGS. 2a-2d show individual snapshots of the animated display of the prepared route data. The prepared route data describe a curve 13 of the predetermined route course located in front of the vehicle 1. FIGS. 2a-2d show here a time sequence when driving on the curve 13 located in front of the vehicle 1 in a corresponding order. FIGS. 2a-2d moreover show the view of the driver of the vehicle 1 through the windshield of the vehicle 1. The view through the windshield of the vehicle 1 is here an augmented reality, which can be implemented by means of the display device 5 in the form of an augmented reality head-up display (AR-HUD).

[0036] The docked display element 7 can be permanently visible to the driver of the vehicle 1. The docked display element 7 is located here in FIGS. 2a-2d above the roadway 9.

[0037] The docked display element 7 can thus float above the roadway 9 and can always be located at the same point with respect to the field of view of the driver of the vehicle 1. The driver of the vehicle 1 can thus be made aware of the predetermined route course. By means of additional driving dynamics data, which can be provided, for example, by a central control unit of the vehicle 1, corresponding sensors, or the like, an angle of inclination a can be determined for the docked display element 7. In the animated display, the docked display element 7 can be inclined relative to the roadway 9 corresponding to the angle of inclination a. Occurring lateral accelerations can thus be visually conveyed to the driver of the vehicle 1 by means of the docked display element 7. The angle of inclination a can change here while driving on the curve 13. This is shown by a greater angle of inclination a in FIG. 2d in relation to FIG. 2a.

[0038] If the vehicle 1 approaches a curve 13 of the predetermined route course located in front of the vehicle, the curve 13 located in front of the vehicle 1 can thus be announced in an animated manner by the announcing display element 8. The docked display element 7 and the announcing display element 8 can initially be displayed superimposed (cf. FIG. 2a). If a predetermined distance, a predetermined duration, or the like to the curve 13 located in front of the vehicle 1 is fallen below, the announcing display element 8 can detach from the docked display element 7 and move along the curve 13 located in front of the vehicle 1. In other words, the announcing display element 8 flies within the augmented reality of the head-up display, which can be generated by the display device 5, through the curve 13 located in front of the vehicle 1. The driver of the vehicle 1 can be notified of the curve 13 located in front of the driver by the animated display by means of the announcing display element 8. In addition, the predetermined route course can be indicated to the driver of the vehicle 1. The movement of the announcing display element 8 within the augmented reality along the curve 13 can be additionally amplified by a stylized tail 12. This is shown in FIG. 2c.

[0039] A predicted lateral acceleration profile can be determined by means of the additional driving dynamics data and/or the curve parameters of the curve 13 located in front of the vehicle 1. The predicted lateral acceleration profile can describe a profile of the lateral acceleration of the vehicle 1 to be expected when driving on the curve 13 located in front of the vehicle 1. In the animated display, the announcing display element 8, which moves within the augmented reality along the curve 13, can be inclined in relation to the roadway 9 during the movement depending on the predicted lateral acceleration profile. The driver can thus be notified of centrifugal forces, which are expected to act on the driver when driving on the curve 13, or the like. A (safety) feeling for the curve 13 which is located in front of the vehicle 1 and is to be driven on in the future can thus be conveyed to the driver of the vehicle 1 already at an early point in time. The driver of the vehicle 1 can decide depending on this, for example, to reduce the speed of the vehicle 1 accordingly.

[0040] The curve 13 located in front of the vehicle 1 can additionally be pointed out by means of a pointing display element 11, which is located at a curve position assigned to the curve 13 within the augmented reality of the head-up display. The pointing display element 11 can be displayed by means of chevrons (from the French for angle, rafter, or zigzag strip) or other (arrow) elements.

[0041] The display by means of chevrons is intuitively comprehensible to the driver of the vehicle 1 and is already known from corresponding direction signs for curves. A chevron density of the pointing display element 11 assigned to the chevrons can describe a curve radius of the curve 13 of the predetermined route course located in front of the vehicle.

[0042] It is also conceivable that the pointing display element 11 moves along within the curve 13 in the context of the augmented reality. In particular, it is thus possible that in elongated curves having possibly variable curve radius, the driver is always made aware of a current curvature course. Moreover, the driver of the vehicle 1 can thus always assess the curve 13 correctly. The safety and in particular the feeling of safety of the driver of the vehicle 1 can thus be increased.
