A method for the transport of elongated workpieces and workers, in a production line which has a rectilinear production section. A plurality of conveyor trolleys, which respectively have an assembly platform that extends over the whole of the conveyor trolley length and is accessible for workers, move in the rectilinear production section jointly along a direction of conveyance and form a convoy in which the assembly platforms of adjacent conveyor trolleys adjoin one another in an at least substantially gap-free manner. The workpieces are arranged in such a way on the assembly platforms that a longitudinal direction of the workpieces is arranged at an angle between 25 and 65, and preferably of about 45, to the direction of conveyance.

The present disclosure involves a method for determining the critical local expansion of a component with an eye toward the appearance of edge cracks based on an expansion of the component in the shaping process. Given a local expansion of the component at the edges that is smaller than the critical local expansion, no edge cracks arise that are larger than 1 m. In particular, at least one expansion test is performed with at least one test component, and a critical overall expansion is determined with the at least one expansion test. The local maximum expansion of the test component is determined that the test component exhibits at the time of the critical overall expansion of the test component, and the local maximum expansion is the critical local expansion.

Fixing a part on a vehicle based on determining a number and a position of locators required to fix a part on a fixture of a vehicle is disclosed. In exemplary aspects, a trained artificial neural network is provided for determining a target number of locators and a target distance between adjacent locators placed on a part to fix the part on a fixture.

A method is provided for producing an assembled cross car beam. That method includes the steps of assembling component parts together to produce an assembled cross car beam, scanning and measuring, by a scanning device the assembled cross car beam and creating component locators in correct positions on the assembled cross car beam for the subsequent installation of component parts such as AHU and instrument panel components.

The stop position of a workpiece is detected by a position detection unit. A control unit calculates and records a difference between the detected stop position (actual stop position) and a reference stop position set in advance. After recording the difference multiple times, the control unit performs a statistical processing of the differences and calculates a compensation amount based on results of the statistical processing. In the next position detecting, the position detection unit is disposed at a compensated position which is obtained by adding the compensation amount to the reference stop position, and in this state, detects the position of a predetermined portion of the workpiece.

An attachment method basically includes detecting a vehicle body side error; a detecting a module side error; correcting the position of a module in the X, Y and Z directions and the angles W, P, and R with respect to each axis based on the vehicle body side and the module side errors; detecting a vehicle body center Bc by measuring both the left and right sides of a vehicle body using the vehicle body side error; detecting a module center by measuring both the left and right sides of the module using the vehicle body side error; and correcting the position of the module based on the vehicle body center and the module center to realize sufficient accuracy by correcting position errors of the vehicle body and the module even in a case in which a positional error exist.

A method for constructing an integrated end structure for a vehicle includes placing a center module for an integrated end structure for a vehicle in a fixture separate from the vehicle, attaching a side bracket to the center module in the fixture to form an assembly, the side bracket configured for holding a light unit of the vehicle, mounting the assembly onto at least a bracket in the vehicle that provides adjustability of the assembly in at least a z-direction, and, after mounting the assembly, mounting a storage compartment module onto the center module and the side bracket.
