Definitions
- the invention relates to a driver assistance system for a motor vehicle comprising a camera, a control and evaluation unit and a display.
- a starting point here is to replace the conventional exterior mirrors, which typically include a housing and a metal-coated glass pane placed in the housing, with so-called electronic or digital exterior mirrors.
- small cameras are attached to the vehicle body in such a way that the rearward traffic can be detected with them and the image data generated with these cameras are then displayed on at least one screen in the motor vehicle.
- the typical dimensions of such cameras, or at least the dimensions of the components that are placed on the outside of the motor vehicle outer skin, are significantly smaller than the dimensions of conventional exterior mirrors, so that in this way the air resistance and consequently the fuel requirements of motor vehicles can be significantly reduced.
- the object of the invention is to provide an advantageous driver assistance system.
- a corresponding driver assistance system is designed for a motor vehicle and includes a camera, a control and evaluation unit and a display.
- the position of the camera is adjustable relative to the motor vehicle by means of an adjusting mechanism, so that by a change in position of the camera relative to the motor vehicle and the detection range of the camera is variable.
- One objective is to reduce the air resistance of the motor vehicle, which is achieved in that the camera is designed as small as possible and positioned as close as possible to the motor vehicle outer skin or integrated into the vehicle structure.
- the driver assistance system is preferably configured and set up so that it not only acts as a replacement for the conventional exterior mirrors, but also supports a driver in various situations by various functions.
- the image data generated by means of the camera are preferably additionally used for a plurality of auxiliary applications, such as, for example, a parking aid, a lane change assistance system or a system for detecting pedestrians.
- auxiliary applications such as, for example, a parking aid, a lane change assistance system or a system for detecting pedestrians.
- no additional or separate sensors are provided for these auxiliary applications, instead the information necessary for this purpose is generated by means of the camera or, if the driver assistance system comprises a plurality of cameras, by means of the cameras of the driver assistance system.
- it is preferable for the various auxiliary applications to have specially adapted positions for the camera or the cameras, and a corresponding position is then approached fully automatically by means of the adjusting mechanism when the corresponding auxiliary application is used.
- the adjustment mechanism is advantageously designed such that with the position and the distance of the camera to the motor vehicle outer skin or the motor vehicle casing is adjustable, so that the camera can be moved away from the motor vehicle quasi.
- the adjusting mechanism preferably allows a rotation or pivoting of the camera about at least one axis of rotation, so that the detection range or the solid angle, which is monitored by means of the camera or cameras, can be selected as freely as possible.
- the driver assistance system is then designed so that the entire environment of the motor vehicle can be optically recorded and monitored.
- the adjusting mechanism for this purpose comprises a carriage to which the camera is attached and which, in particular with the aid of a rail, is displaceable along a trajectory.
- the carriage is designed for this purpose, for example, in the manner of a double-T-carrier and by means of a Rail with incorporated groove out, one end of which is connected to the body of the motor vehicle.
- the trajectory has a curvature or bending, so that the camera moves on a curved or even spiral-shaped path, in some also rotating around the trajectory, when the carriage is displaced.
- the optical axis of the camera is preferably pivoted horizontally by a few degrees, whereby the angle between the optical axis and the central axis of the vehicle slows down. The viewing direction, if you will, is steered in this way more towards the motor vehicle. Further preferably, the optical axis is tilted down when extending the camera down, so in the direction of the driving surface.
- the adjusting mechanism comprises a telescopic tube or a telescopic arm, whose one end is connected to the body of the motor vehicle and at the other end of the camera is positioned.
- the telescopic tube again has a curvature or bending, so that the camera moves on an extension of the telescopic tube on an arcuate or even spiral-shaped path.
- a corresponding adjustment mechanism with slide or telescopic tube can thereby be relatively easily implemented and integrated into the body of the motor vehicle.
- the adjusting mechanism expediently comprises a drive, wherein a spindle drive or a lateral drive with cable pull mechanism, similar to a window regulator mechanism, is preferably used for adjusting the carriage or the telescopic tube.
- the adjustment is advantageously carried out as simple as possible to ensure the highest possible life expectancy for the adjustment.
- the adjustment mechanism is preferably controlled by the control and evaluation unit of the driver assistance system, wherein the control takes place in such a way that the position of the camera automatically as a function of the driving situation is varied. It is particularly advantageous in this case to vary the position of the camera automatically as a function of the driving speed of the motor vehicle.
- a fully automatic speed-dependent change takes place between three camera positions, in each of which different auxiliary applications are active.
- the parking aid is then active and the camera is positioned and aligned in such a way that a curb, if present, is captured by the camera and displayed to the respective driver on the screen.
- the pedestrian recognition is activated, in which by means of the camera the largest possible space area is detected and monitored, so possibly through the use of additional cameras of the driver assistance system in the sum of a panoramic view (surround view) or an all-round monitoring is realized.
- the lane change assistant is activated, in which the camera monitors a specific angle range, in particular the so-called “dead angle” with respect to the motor vehicle and, in addition, moves the camera as close as possible to the motor vehicle outer skin or on It is alternatively or additionally possible for the respective driver by means of operating elements to activate and deactivate various auxiliary applications, in which case the position of the camera is predefined depending on the selected auxiliary application The selection of the respective driver then replaces the fully automatic speed-dependent default.
- the driver assistance system either additional sensors, for example, to detect the driving speed of the motor vehicle, or the control and evaluation of the driver assistance system is fed by external source with additional information.
- This makes it possible to make a camera positioning, which is designed for the operation of the motor vehicle with a trailer.
- a fixed position for the camera is provided for the operation of the motor vehicle with trailer, in which the camera is positioned at the greatest possible distance from the vehicle body, so in particular as far as possible, which is then adjusted as soon as a trailer is detected by sensors.
- the corresponding information input into the control and evaluation unit via an operating element in the motor vehicle preferably a warning light informs the respective driver that the driver assistance system is currently in a mode that is responsible for the operation of the Motor vehicle is designed with a trailer.
- the side region of the motor vehicle has proven to be expedient and therefore preferably a camera is positioned on both sides of the motor vehicle.
- a position in the area of the front wheel arches and at the level is advantageous, both with respect to the vehicle extent in the longitudinal direction and in the height direction, on which the wiper linkage is typically positioned.
- the two cameras on the sides of the motor vehicle are supplemented by another camera at the rear of the motor vehicle, the image data of the three cameras in an operating mode of the driver assistance system for the realization of an electronic rearview mirror, in particular as a replacement for the classic exterior mirrors on the one hand and the classic Inner mirror on the other hand, to be combined with each other.
- the three cameras are preferably aligned and positioned such that the three space regions detected by the cameras adjoin one another or partially overlap, so that the three cameras collectively cover a very large spatial area, which is then reproduced in the manner of a panoramic image on the screen in the motor vehicle.
- the three cameras thereby advantageously generate individual frames synchronously at fixed time intervals, wherein in each case the individual images of the three cameras which were generated at the same time are merged to form an overall image. the. These overall images are then displayed on the screen or the display in the motor vehicle.

- a driver assistance system 2 described below by way of example and outlined in FIG. 1 comprises three cameras 4, a control and evaluation unit 6 and a screen 8. It is designed for a passenger vehicle 10 and accordingly installed in such a vehicle.
- the screen 8 is integrated in a manner not shown in a central console in the passenger compartment of the passenger car 10 and the control and evaluation unit 6 is housed in the engine compartment of the passenger car 10.
- telescopic arms 12 is shown schematically in FIG 4 and includes a drive unit 14 which is formed as a spindle drive or as a lateral drive with cable pull mechanism and fixed laterally in the engine compartment.
- the telescopic arm 12 which is guided by the vehicle outer skin 16 or vehicle skin, extend laterally, whereby the camera 4 can be moved relative to the vehicle outer skin 16.
- the telescopic arm 12 is constructed of three coaxially arranged hollow bodies with a rectangular cross section, so that the outer hollow body acts as a transport carriage 15 for the camera 4, with which the camera 4 is displaceable along a trajectory.
- the position of the camera 4 can be adjusted with the aid of the telescopic arm 12, wherein the detection range of the camera 4 changes depending on the position of the camera 4.
- the control and evaluation unit 6 is now set up such that the drive units 14 of the two telescopic arms 12 are activated as a function of the travel speed of the passenger car 10 determined by means of a sensor 18, so that the positions of the two cameras 4 at the ends of the two telescopic arms 12 are fixed, predetermined depending on the driving speed and adjusted via the drive units 14.
- the positions of the two cameras 4 are predetermined such that the two telescopic arms 12, as shown in FIG 5, are fully extended to a speed of 30 km / h and are retracted from this speed limit with increasing driving speed of the passenger car 10 in a linear relationship so that the two telescopic arms 12 are fully retracted from a speed of 70 km / h.
