Definitions
- the invention relates to a method for displaying objects in the vicinity of the vehicle according to the preamble of patent claim 1.
- the near range around the vehicle is usually measured with ultrasonic sensors.
- the sensors offer a maximum range of 1.5 m.
- the display of an obstacle or an object can be done acoustically and / or optically.
- the use of ultrasonic sensors has the disadvantage that the range is very limited and no accurate object position can be determined due to the lack of triangulation.
- no statements about the extent of the object can be made and a statement whether the object is in the vehicle lane or not, is limited.
- the display of the distance of the vehicle to the object is usually simple.
- the display takes place, for example, via two display units, one of which is arranged in the front of the vehicle and one in the rear of the vehicle, and in each case comprises two groups of light-emitting diodes.
- the distance from the vehicle to the object is indicated by the number of light emitting diodes, the more the light emitting diodes burn, the closer the object is to the vehicle.
- a stylized vehicle is displayed from the top view, in which the area around the vehicle is represented front and back with three groups of beams each, which are raised depending on the proximity to the object.
- the display is only for objects in the back space on a large display that is part of a head unit.
- a cloud is placed around the location of the object and the expected contact point with the vehicle. The cloud is tricolor depending on the proximity to the vehicle contour.
- the object of the invention is to provide a method for displaying objects in the vicinity of the vehicle, with which a user can quickly and safely distinguish between dangerous and non-dangerous objects.
- the invention achieves this object by providing a method for displaying objects in the vicinity of the vehicle with the features of patent claim 1.
- a lane of the vehicle is continuously determined and correlated with a determined object position, wherein the color of a displayed object in Depending on the object position to the lane of the vehicle is set.
- the object can be displayed with a first color, for example yellow, if it collides with the lane within a first distance range.
- the object may be displayed with a second color, such as red, if it is within a second range of distance that is less than the first range of distance, i. closer to the vehicle, collided with the lane.
- the object can be displayed in a third color, such as green, if it is outside the lane for all distance ranges.
- the assignment of the color takes place exclusively as a function of the distance of the object to the vehicle, without taking into account the lane.
- the distance is only relevant for the driver when the object is in its future lane. Therefore, the colors of the displayed objects are not fixed, but change depending on the lane and the distance of the object to the vehicle.
- a stationary object may depend on the vehicle selected lane once have a red color, a yellow or green color.
- the future lane of the vehicle can be determined, for example, from a current steering angle.
- the vehicle is shown with the vehicle near area and with the specific objects as a top view on a display unit.
- the calculated traffic lane is displayed on the display unit.
- the driver immediately recognizes whether the future lane collides with a specific object. In addition, this is supported by the appropriately used warning color.
- signals of radar sensors are evaluated by means of a triangulation method in order to determine the object position.
- a significantly longer range can be achieved compared to ultrasonic sensors, up to 30 m.
- a triangulation and thus an exact position determination of the objects are possible by the measuring principle.
- the radar sensors have the further advantage that the expansion principle of the radar waves also objects can be detected, which are behind another object.
- complex objects are determined by an evaluation of individual points and their direction of expansion is estimated. So it is possible, even without imaging radar, from several individual points, the close to each other lie on a complex object and its expansion direction.
- the objects can be displayed, for example, by a geometric base area which is surrounded by larger, same geometric base areas, which act as an auras to indicate the assumed object extent, whereby circles and / or rectangles are preferably displayed as geometric base areas.
- the color intensity can be performed, for example, decreasing from the inside to the outside.
- transition between the used primary colors, green, yellow and red can be represented with transitions of decreasing color intensity, which can be easily represented by the aura.
- transitions arise, for example, when the driver changes a selected steering wheel angle and thus the original lane or when the distance of the vehicle to an object that collides with the lane changes.
- a desired driving lane can be calculated for parking and displayed on the display unit in a fourth color.
- the current traffic lane can be displayed in a fifth color on the display unit.
- Fig. 1 is a schematic representation of a
- FIG. 2 is a schematic representation of a
- Fig. 3 is a schematic representation of a
- a plan view of a vehicle 1 recognized objects Ol, 02, 03 with associated aura AOl, AO2, AO3 to display the estimated direction of expansion and a lane 3 are displayed ,
- the lane 3 is calculated and displayed by evaluating the current steering angle.
- a first distance range 2 to the vehicle and two further ranges 4, 5 for displaying the range of the radar sensors are displayed.
- Embodiment is the area shown in front of or behind the vehicle 1 about 7m distance, the side areas show approximately 2.5m.
- the side areas show approximately 2.5m.
- the representation of the individual detected objects O1, O2, O3 takes place in a circular form, which according to their propagation direction is surrounded by an aura AO1, A02, A03.
- This has the advantage that a complex object, such as a wall or a person in front can be "composed" of many circles without major problems.
- the aura avoids gaps between the individual rectangles.
- the first detected object Ol which collides with the probable traffic lane 3 of the vehicle 1 in the first distance range 2, is displayed in a warning color "red", which is indicated by the rough hatching of the object O1 and its aura AO1
- the object 02 collides outside the first one
- the third object 03 does not collide within or outside the distance range 2 with the expected lane 3 and is therefore displayed in a clear color "green”, which is indicated by the object 03 and its aura A03 having no hatching.
- the first detected object Ol which collides in the first distance range 2 with the probable traffic lane 3 of the vehicle 1 is displayed in a warning color "red", which is indicated by the coarse hatching of the object 01 and its aura
- the first detected object oil does not collide with the anticipated lane 3 of the vehicle 1, but it lies in the first one Distance range 2. Therefore, the detected object oil is displayed in the weaker warning color "yellow", which is indicated by the fine hatching of the object oil and the associated aura AO1
- the third object 02 does not collide within or outside the distance range 2 with the anticipated traffic lane 3 and is therefore displayed in the all-clear color "green", which is indicated by the fact that the object 02 and its aura A02 have no hatching.
- the object 03 collides outside the first distance range 2 with the lane 3 and is therefore represented in the weaker warning color "yellow", which is indicated by the fine hatching of the object 03 and the associated aura A03.
- the driver receives the important information for him, whether a detected object is in his lane or not. If the object is in its future lane, this is signaled to the driver by a corresponding warning color, for example red or yellow, depending on the distance to the vehicle. If the object is not in its future lane, this can be indicated by a different color, for example green.
- the display method can also be used for future assistance systems that assist the driver in a parking operation.
- future assistance systems that assist the driver in a parking operation. For example, such systems calculate a planned parking trajectory and display it on the display system. The driver now only has to cover the actual lane and the target trajectory in order to find the ideal lane for parking.
