Definitions
- the invention relates to a device for connecting a target object to a towing vehicle for the functional test of an environment-detecting driver assistance system according to the preamble of claim 1, as known for example from DE 1020121 10586 A1.
- the deformability of the hoses is preferably dimensioned so that the hoses can transmit normal train and compressive loads by acceleration or braking of the towing vehicle, for example, up to a predetermined limit of acceleration in the direction of travel as well as in the direction of rotation a defined tracking, when exceeded in particular due to a Impact of the test vehicle on the target object, however, the hoses are deformed and the target object in the direction of the towing vehicle or laterally can be moved to it and there is no significant damage to the target or test vehicle.
- This device is thus part of a test arrangement for driving tests, in which a target object can be pulled behind a towing vehicle, in particular to test environment-comprehensive driver assistance system especially in the field of close collision or collision driving tests.
- a collision with a test vehicle can be readjusted to the target object.
- the invention relates to a development of the known from the above-mentioned document device for connecting the target object with the towing vehicle.
- an arbitrary target object preferably a light and relatively soft vehicle dummy (for example a so-called baloon car on castors or wheels), can be connected to the towing vehicle by means of the connecting device and dragged behind it.
- DE 202009008752 U1 or DE 7123421 U1 or DE 1 179 399 A1 disclose devices for towing abandoned vehicles. Such devices are due to the small distance between towing vehicle and target object for use in driving tests usually unsuitable.
- the object of the present invention is to provide a particularly suitable embodiment of this device.
- An essential idea of the invention is that the distance of the hoses from one another in the transverse direction over the length of the hoses in the longitudinal direction is different and thus deformation zones of the hoses are defined at which the hoses are deformed in a collision of the test vehicle. It should be made clear that this applies in the normal operating state, ie in the pressurized state.
- the distances are preferably defined accordingly by means of the connecting elements by at least one of the connecting elements, for example, a greater width of the hose guide in the transverse direction deviating from the width of the hose guide to another in the longitudinal direction spaced connection element has. In principle, a smaller width compared to the other connecting elements would also be conceivable. In addition to the width of the connecting elements in the transverse direction and their distance from one another determines the deformation of the hose.
- FIG. 1 shows a corresponding test arrangement, as has already been described in general form in the unpublished DE 1020121 10586 A1 and, additionally, for the sake of understanding, reference is also made to this.
- the target object 1 is connected to the towing vehicle 3 via the device 4 according to the invention, wherein for the sake of simplicity in the present figure only 2 hoses 5 are shown, which are connected via end connection means 6 to the towing vehicle 3 on the one hand and the target object 1 on the other hand and via spaced connecting means 8 are also connected to each other in the transverse direction.
- the inner volumes of the hoses (5) are hydraulically or pneumatically pressurized.
- the hoses 5 serve essentially for the transmission of normal positive as well as negative acceleration forces from the towing vehicle (3) to the target object (1), as usual by normal acceleration or braking operations in road traffic. moreover serve the hoses and their transverse thereto arranged connection means for tracking and stabilizing the target object 1 also during driving situation with lateral acceleration forces, such as cornering or lane change operations.
- the transverse connecting means the overall stiffness of the device is defined and can be adjusted accordingly.
- the test vehicle 7 comes with its surroundings detect sensor 15 and the driver assistance systems in the vicinity of the target object 1 and detects this, as to be sketched by the beams 16.
- the differential speed of the test vehicle 7 can be so high in relation to the towing vehicle 3 that the protective measures introduced are insufficient and a collision of the test vehicle 7 together with the target object 1 occurs. It should be expressly pointed out that such a collision in the normal operation of the vehicle is just to be avoided, but in the present driving tests, for example, deliberately oversteer the interventions of the assistance system is deliberately brought about the reactions of the assistance systems just before and during to be able to test such a collision.
- the distance X (TO) between the target object 1 and towing vehicle 3 is significantly reduced, for example by several meters, thus allowing a test until impact, without causing significant damage to the test vehicle 7 or target object 1 would come.
- a subsequent evasion or further deceleration of the test vehicle 7 becomes possible.
- the distance ( ⁇ , ⁇ ) in the transverse direction of the hoses to each other over the length of the hoses in the longitudinal direction away (B0 + BY).
- one of the connecting elements may have a smaller width of the hose guide, so that the outer tubes do not extend outwardly, but curved inwards and of course a larger number of different width connecting elements can be used to the deformation of the hose even closer define.
- the hose guide of the connecting element (8.Y) is wider than the adjacent connecting elements (8.0) and also the distance in the longitudinal direction (X2) of the wider connecting element (8.Y) to the adjacent connecting elements (8.0 ) greater than the distance (X1) of these adjacent connecting elements (8.0) to the other connecting elements (8.0) or the end-side attachment (6).
- the middle tube can be quite straight, but of course by the different distances of the connecting elements in the lower and outer tubes and the distance in the transverse direction between the middle Hose and the respective outer hoses is correspondingly different.
- Figures 2 and 3 show in each case 2 views of a particularly suitable connecting element 8, which is spaced between towing vehicle and target for guiding the hoses and their positioning at a predetermined distance from each other as well as with sufficient distance from the road and for transmitting the required forces, in particular Transverse forces in the transverse direction Y on the hoses 5 towards the target object allows and thus also allows a track stabilization and targeted guidance of the target object both in straight-ahead driving and especially in cornering and driving tests with simulated lane change.
- a connecting element 8 could be used, provided that its width is different from the distance of the hoses in the end points.
- each connecting element 8 has at least one pair of rollers (1 1) to the road towards, the rollers preferably have an identical axis position perpendicular to the direction of travel X to each other and thus allow straight-line running of the connecting element.
- a pickup is provided, which supports the respective tube in the vertical direction (Z) as well as at least one transverse direction (Y) at points, but preferably over a predetermined length in the longitudinal direction (X).
- the transducer has a metallic profile piece, here an angle profile piece of predetermined length in the longitudinal direction (X), which supports the hose over this length in the vertical direction (Z) and at least one transverse direction (Y).
- the profile piece supports the tube in both transverse directions, as outlined for example in the upper receptacle for the tube 5C, but just sufficiently and so also realized for the tubes 5A and 5B, respectively next to the protection in the vertical direction down to the roadway as well as just to the respective outside in the transverse direction.
- the protective function preferably comprises both a protection against direct contact of the hose with the road and the penetration of flying objects, such as stones of accidents as well as from the sides at least for a certain predetermined area of the hose.
- At least two of the transducers at least on the underside and / or an outer side protruding guides (12) are provided for tensioning belt 10, as these are particularly well recognized in Figure 3. These guides 12 are used on the one hand for the exact positioning of the tensioning belt 10 in the direction of travel X, so that they do not slip even when occurring acceleration or braking operations of the towing vehicle and thus taking place via the hoses 5 power transmission.
- the connecting element (8) according to FIGS. 3 and 2 in this case has receivers for two hoses (5A, 5B) in a plane parallel to the roadway and a third receiver for the third hose (5C) spaced apart from holding means (17) to this plane.
- such an arrangement with 3 hoses has a triangular cross-sectional profile, which allows particularly good tracking from the towing vehicle towards the target object.
- the specific design of the corresponding holding means 17 is structurally largely freely designable, but preferably chosen so that a projection of the upper tube 5C in the plane of the tubes 5A and 5B would be centrally between the tubes 5A and 5B.
- the connecting element described here is thus preferably used for the positions of at least two deformable hoses for a device according to DE 1020121 10586 A1 for connecting a target object to a towing vehicle for functional testing of a driver assistance system of a test vehicle for carrying out driving tests, in particular collision-near and collision-prone driving tests between the test vehicle and the target object (1) and thus ultimately in a corresponding test arrangement.
