专利说明:

[0001] [0001] The present invention relates to an obstacle avoidance system for a camera arm for observing traffic to the rear of a vehicle, and to a vehicle having the obstacle avoidance system.
[0002] [0002] Contemporary vehicles have classic rearview mirrors with a reflective surface in order to ensure visibility to the rear of the vehicle.
[0003] [0003] Since rearview mirrors are also mounted, inter alia, in the external region and have relatively large dimensions, they result in a comparatively high wind resistance. Furthermore, the visibility to the rear can be adversely affected by external influences such as rain and dirt on the side windows and the mirror. In addition, the classic mirror principle is not suitable for carrying out additional intelligent functions.
[0004] [0004] Digital camera arms can replace the classic rearview mirror. The digital camera arm has for this purpose a camera which records images of the area to be monitored to the rear of the vehicle and makes these images available to the driver, in particular, via a display device.
[0005] [0005] However, the camera arm undesirably blocks the driver’s view in various driving situations. In addition, the camera arm on the outside of the vehicle is frequently subjected to mechanical loading such as, for example, a collision.
[0006] [0006] An object of the present invention is to provide an improved obstacle avoidance system for a camera arm for observing traffic to the rear of a vehicle.
[0007] [0007] This object is achieved by the subjects of the independent patent claims. Embodiments and developments can be inferred from the dependent patent claims, the description and the figures.
[0008] [0008] According to one aspect, an obstacle avoidance system for a camera arm for observing traffic to the rear of a vehicle comprises the camera arm which has a camera, a guide element which extends from a lateral surface of the bodywork of the vehicle to a roof surface of the bodywork of the vehicle, wherein the camera arm is arranged on the guide element so as to be slidable along the guide element from a position of rest on the roof surface to a working position on the lateral surface and vice versa.
[0009] [0009] The guide element preferably runs over the curvature of the bodywork of the vehicle, in particular over the curvature of the bodywork from the lateral surface to the roof surface of the vehicle.
[0010] [0010] The camera arm preferably runs from the working position to the position of rest and vice versa along a cycloidal path.
[0011] [0011] The camera arm perfectly comprises a rod-shaped projection, wherein the camera is also preferably arranged at an end furthest away from the vehicle.
[0012] [0012] The camera arm is preferably configured to hold and/or position the camera. Furthermore, the camera arm is configured to protect the camera, in particular from external environmental influences. The protective function of the camera arm with respect to the camera relates preferably to protection against a mechanical effect such as a mechanical shock or shock loading from a horizontal and/or lateral direction; in other words, against a mechanical effect {from the front, from the rear and/or from the side of the vehicle.
[0013] [0013] In this way, a classic rearview mirror of a vehicle can be improved by an improved obstacle avoidance system for a camera arm.
[0014] [0014] The camera arm therefore preferably avoids mechanical influences which occur to the side of the vehicle, in particular to the side of a driver's cab of the vehicle.
[0015] [0015] In this way, an improved obstacle avoidance system for a camera arm for observing traffic to the rear of a vehicle is provided.
[0016] [0016] In one preferred embodiment, the obstacle avoidance system for a camera arm comprises a sliding device which is connected to the camera arm and is arranged on the guide element so as to be slidable along the guide element.
[0017] [0017] The sliding device and the guide element are preferably embodied in such a way that the sliding device can slide over the guide element.
[0018] [0018] In this way, an improved obstacle avoidance system for a camera arm for observing traffic to the rear of a vehicle is provided.
[0018] [0018] In one preferred embodiment, the guide element has at least one first guide rail and a control cam, wherein the first guide rail is configured to guide the camera arm along the guide element, and the control cam is configured to control an alignment of the camera arm along the guide rail.
[0020] [0020] The first guide rail and the control cam are preferably arranged parallel to one another in a direction of travel of the vehicle.
[0021] [0021] The guide element preferably has a first guide rail and a second guide rail, wherein the control cam is arranged between the first guide rail and the second guide rail.
[0022] [0022] In this way, an improved obstacle avoidance system for a camera arm for observing traffic to the rear of a vehicle is provided.
[0023] [0023] In one preferred embodiment, the sliding device has a bearing point on which the camera arm is rotatably mounted at a first connecting point of the camera arm.
[0024] [0024] In this way, the orientation of the camera arm with respect to the sliding device and therefore with respect to the vehicle can be changed.
[0025] [0025] In this way, an improved obstacle avoidance system for a camera arm for observing traffic to the rear of a vehicle is provided.
[0026] [0026] In one preferred embodiment, the obstacle avoidance system for a camera arm comprises a rider which is arranged on the control cam, wherein the sliding device has a pulling means which connects the at least one rider to the 5 camera arm at a second connecting point of the camera arm via a deflection point arranged on the sliding device.
[0027] [0027] In this way, the distance of the rider from the vehicle directly influences the orientation of the camera arm.
[0028] [0028] The first connecting point and the second connecting point are preferably located at two corners of the camera arm. This can ensure that in every position the camera arm is arranged horizontally on the guide element with respect to the vehicle.
[0029] [0029] In this way, an improved obstacle avoidance system for a camera arm for observing traffic to the rear of a vehicle is provided.
[0030] [0030] In one preferred embodiment, the distance between the control cam and the vehicle varies over the length of the guide rail.
[0031] [0031] In this way, the rider is arranged closer to or further away from the vehicle, depending on where the rider is located on the control cam. The rider is preferably arranged closer to the vehicle when the sliding device is in the working position than when the sliding device is in the position of rest. Conversely, the rider is preferably arranged further away from the vehicle when the sliding device is in the position of rest than when the sliding device is in the working position.
[0032] [0032] In this way, the pulling means 1s tensioned or relieved of tension and the camera arm is thus influenced in its orientation. Depending on the configuration of the control cam and therefore on a progression of the distance of the control cam from the vehicle, a different orientation of the camera arm is produced during the sliding of the camera arm on the guide rails.
[0033] [0033] Depending on the configuration of the control cam, a different orientation of the camera arm is produced in accordance with the position of the sliding device on the guide element. Basically, different obstacle avoidance manoeuvres of the camera arm are possible. The camera arm preferably always has a horizontal position.
[0034] [0034] Therefore, the control cam can be configured in such a way that, in the position of rest, the camera arm is placed flat against the vehicle, and, in the working position, the camera arm projects perpendicularly from the vehicle.
[0035] [0035] The distance of the rider from the vehicle therefore varies. In particular, the distance of the rider from the vehicle varies along the control cam.
[0036] [0036] In this way, an improved obstacle avoidance system for a camera arm for observing traffic to the rear of a vehicle is provided.
[0037] [0037] In one preferred embodiment, the sliding device has an opening in which the rider is movably arranged.
[0038] [0038] The rider is preferably arranged within the opening and not directly with the sliding device. The rider is instead held in the opening by the pulling means.
[0039] [0039] In this way, an improved obstacle avoidance system for a camera arm for observing traffic to the rear of a vehicle is provided.
[0040] [0040] In one preferred embodiment, the obstacle avoidance system for a camera arm comprises a stop having a latching element, wherein, in the working position, the camera arm bears against the stop and is fastened to the stop by the latching element.
[0041] [0041] In this way, an improved obstacle avoidance system for a camera arm for observing traffic to the rear of a vehicle is provided.
[0042] [0042] In one preferred embodiment, the obstacle avoidance system for a camera arm comprises at least one surroundings sensor which is configured to determine surroundings data which relate to the surroundings of the vehicle, a drive device which is configured to move the sliding device along the guide element, and a control device which is configured to control the drive device in accordance with the determined surroundings data in such a way that the sliding device is moved along the guide element.
[0043] [0043] The surroundings data preferably include obstacles in the vicinity of the vehicle, in particular to the sides of the vehicle.
[0044] [0044] The camera arm is preferably configured to hold and/or position the at least one surroundings sensor. Furthermore, the camera arm is configured to protect the at least one surroundings sensor, in particular from external environmental influences.
[0045] [0045] The surroundings sensor preferably comprises a proximity sensor, a thermometer and/or a moisture sensor.
[0046] [0046] According to one aspect, a vehicle having an obstacle avoidance system for a camera arm, such as is described here, is provided.
[0047] [0047] The vehicle is preferably a vehicle which drives in an at least partially automated fashion.
[0048] [0048] The appended drawings are intended to convey further understanding of the embodiments of the invention. The appended drawings illustrate embodiments and serve, in conjunction with the description, to clarify concepts of the invention.
[0049] [0049] Other embodiments and many of the specified advantages become apparent with regard to the drawings. The illustrated elements of the drawings are not necessarily shown true to scale with respect to one another.
[0050] [0050] In the drawings: Fig. 1 shows a side view of the obstacle avoidance system for a camera arm in the working position; Fig. 2 shows a side view of the obstacle avoidance system for a camera arm in the position of rest; Fig. 3 shows a front view of the obstacle avoidance system for a camera arm in the position of rest; and Fig. 4 shows a side view of a progression of the camera arm from the position of rest to the working position.
[0051] [0051] Fig. 1 shows an obstacle avoidance system 10 for a camera arm 20. The obstacle avoidance system 10 comprises a camera arm 20 which is attached to a vehicle 30 via a guide element 40. The vehicle 30 has a lateral surface 31 and a roof surface 32. The guide element 40 extends along the bodywork of the vehicle 30 over the lateral surface 31 to the roof surface
[0052] [0052] The camera arm 20 is slidably arranged on the guide element 40 in such a way that it can be slid from the working position A along the lateral surface 31 in the vertical direction Z over the curvature of the bodywork of the vehicle
[0053] [0053] Fig. 2 shows the obstacle avoidance system 10. In contrast to fig. 1, the camera arm 20 is now in the position of rest R instead of in the working position A. If the camera arm 20 is arranged on the roof surface 32 of the vehicle 30, it is located in what is referred to as the position of rest R. Although the camera which is arranged on the camera arm 20 can also capture traffic to the rear of the vehicle 30 in the position of rest R, the function of the camera in the position of rest R is not usually used as a rearview mirror and/or side mirror.
[0054] [0054] The camera arranged on the camera arm 20 is intended to be spaced apart from the vehicle 30 in the working position A, in order to be able to carry out the function as a digital side mirror. In other words, the camera must be spaced apart laterally from the vehicle 30 so that the camera assumes a sufficient viewing angle with respect to the traffic to the rear of the vehicle 30. The camera arm 20 is therefore embodied as a rod-like projection which, in the working position A, extends laterally outward from the lateral surface 31 of the vehicle 30. As can be seen in fig. 2, in the position of rest R on the roof surface 32 of the vehicle 30, the camera arm 20 does not extend in the vertical direction Z from the vehicle 30. Instead, the camera arm 20 rests as flat as possible on the roof surface 32 of the vehicle 30 and extends in the horizontal direction Y. In this way, in the position of rest R, the camera arm 20 offers as little air resistance as possible in the direction of travel X. To do this, the camera arm 20 changes its orientation with respect to the guide element 40 on the path from the working position A to the position of rest R. In other words, the camera arm 20 is pivoted with respect to the guide element 40, while the camera arm 20 is slid from the working position A to the position of rest R. In this case, the camera arm 20 is pivoted through 90° with respect to the guide element 40, between the working position A and the position of rest R. In this way, the camera arm 20 does not change its horizontal orientation along the horizontal direction Y while the camera arm 20 is moving between the working position A and the position of rest R.
[0055] [0055] Fig. 3 shows the obstacle avoidance system 10 as it can be seen from the horizontal direction Y. The guide element 40 comprises a first guide rail 41 and a second guide rail 43 which extend parallel to one another in the direction of travel X, from the lateral surface 32 of the vehicle 30 to the roof surface 31 of the vehicle 30. Furthermore, the guide element 40 has a control cam 42 which runs between the first guide rail 41 and the second guide rail 43. The camera arm 20 is in the working position A and is fastened in the working position A by the latching element 90. The control cam 42 is configured to rotate the camera arm 20 along the guide element 40 with respect to the guide element 40 in such a way that the horizontal orientation of the camera arm 20 in the horizontal direction Y does not change.
[0056] [0056] Fig. 4 shows a more detailed view of the obstacle avoidance system 10. The obstacle avoidance system 10 has a sliding device 50 which is connected to the camera arm 20 and is arranged on the guide element 40 so as to be slidable along the guide element 40. In this way, the camera arm 20 can be slid on the guide element 40 by means of the sliding device
[0057] [0057] Since the guide element 40 extends from the lateral surface 31 of the vehicle 30 onto the roof surface 32 of the vehicle 30, the orientation of the sliding device 50 changes from a horizontal orientation in the working position A to a vertical orientation in the position of rest R. So that the camera arm 20 does not change its horizontal orientation during the sliding from the working position A to the position of rest R, the orientation of the camera arm 20 during the sliding with respect to the sliding device 50 has to change in accordance with the sliding.
[0058] [0058] For this purpose, the obstacle avoidance system 10 has a pulling means 70 which is preferably embodied as a cable. The pulling means 70 is fastened to a second connecting point 22 of the camera arm 20. The first connecting point 21 and the second connecting point 22 are selected in such a way that, in every position of the camera arm 20 in a vertical direction Z on the guide element 40, they are arranged in a line along the vertical direction Z. The pulling means 70 is configured in such a way that it controls the distance between the second connecting point 22 and the vehicle 30. For this purpose, the pulling means 70 connects the second connecting point 22 to the control cam 42 via a rider 60. A progression of the control cam 42 with respect to the distance from the vehicle 30 therefore also influences the distance between the second connecting point 22 and the vehicle 30. The control cam 42 is embodied in such a way that the distance from the lateral surface 31 is shorter than the distance from the roof surface
[0059] [0059] For free movement of the rider 60 toward or away from the vehicle 30, the sliding device 50 has an opening 53 in which the rider 60 can freely move.
[0060] [0060] This ensures that, in the working position A, the camera arm 20 extends laterally away from the lateral surface 31 of the vehicle 30, and, in the position of rest R, it does not project upwardly from the roof surface 32 of the vehicle
30.
