Abstract
A connecting device (4) for connecting a target object (1) to a towing vehicle (3) for functionally testing a driver assistance system of a test vehicle (7) for test driving, includes two deformable pressurizable hoses that extend in a longitudinal direction (e.g. from the towing vehicle to the target object) and that are connected to each other transversely to the longitudinal direction. A test arrangement includes the towing vehicle connected to the target object by the connecting device.
Claims17
A device for connecting a target object to a towing vehicle for functionally testing a driver assistance system of a test vehicle for test driving, especially for near-collision and collision test driving, comprising:
- at least two deformable hoses, which are configured and adapted to be connected at two opposite ends thereof to the towing vehicle and to the target object respectively, and which are effective to transmit acceleration forces from the towing vehicle via the hoses to the target object, wherein an internal volume of the hoses can be hydraulically or pneumatically pressurized,
- at least one connecting element, wherein the hoses are connected to one another transversely to a longitudinal direction by the at least one connecting element, and
- guide rollers and/or sliding elements that are arranged on at least one of the connecting elements and that are oriented toward a roadway on which the towing vehicle is supported.
A test arrangement for functionally testing a driver assistance system of a test vehicle for test driving, especially for near-collision and collision test driving, between the test vehicle and a target object,
- wherein the test arrangement comprises the towing vehicle, the target object, and a device that connects the target object to the towing vehicle,
- wherein the device comprises:
- at least two deformable hoses, which are configured and adapted to be connected at two opposite ends thereof to the towing vehicle and to the target object respectively, and which are effective to transmit acceleration forces from the towing vehicle via the hoses to the target object, wherein an internal volume of the hoses can be hydraulically or pneumatically pressurized, and
- at least one connecting element, wherein the hoses are connected to one another transversely to a longitudinal direction by the at least one connecting element.
A device for connecting a target object to a towing vehicle for functionally testing a driver assistance system of a test vehicle for test driving, especially for near-collision and collision test driving, comprising:
- at least two deformable hoses, which are configured and adapted to be connected at two opposite ends thereof to the towing vehicle and to the target object respectively, and which are effective to transmit acceleration forces from the towing vehicle via the hoses to the target object, wherein an internal volume of the hoses can be hydraulically or pneumatically pressurized,
- at least one connecting element, wherein the hoses are connected to one another transversely to a longitudinal direction by the at least one connecting element, and
- connection fixtures on the two opposite ends of the hoses configured and adapted to be connected to the towing vehicle and to the target object respectively.
A towing connector device for connecting a target object to a tow vehicle via the towing connector device so that the tow vehicle can tow the target object via the towing connector device, which comprises:
- plural deformable pressurizable hoses that each extend longitudinally in a longitudinal direction,
- plural transverse elements that are spaced apart from one another in the longitudinal direction, and that each extend in a transverse direction transverse to the longitudinal direction, and that connect the plural hoses to one another in the transverse direction,
- a first connection fixture at a first end of the hoses, wherein the first connection fixture is configured and adapted to be connected to the tow vehicle, and
- a second connection fixture at a second end of the hoses opposite the first end in the longitudinal direction, wherein the second connection fixture is configured and adapted to be connected to the target object,
- wherein:
- the hoses are configured and adapted to transmit tension forces through the hoses in the longitudinal direction, sufficient for the tow vehicle to tow the target object via the towing connector device, and
- the hoses are configured and adapted to transmit compression forces through the hoses in the longitudinal direction up to a compression load limit, and the hoses are configured and adapted to buckle or bend out of the longitudinal direction whereby the first and second connection fixtures move closer to one another when the hoses are subjected to compression forces in the longitudinal direction exceeding the compression load limit.
