A headlamp aiming method for a vehicle includes measuring, by a height measurement instrument, at least two reference heights of at least two reference areas along a body of the vehicle. The height measurement instrument is positioned external of the vehicle, and one of the at least two reference heights is indicative of a height of a headlamp of the vehicle. The method further includes determining a vehicle pitch and a headlamp height variation of the vehicle based on the measured reference heights, calculating a modified headlamp position based on the vehicle pitch, the headlamp height variation, and a standard headlamp position, and aiming a headlamp of the vehicle based on the modified headlamp position.

In a method for securing a high voltage on-board electric grid of a motor vehicle for repair and/or maintenance of the motor vehicle, the energy inflow of an energy supply unit into the onboard electric grid is blocked during or after a voltage disconnection of the high-voltage on-board electric grid, in which an energy inflow of the energy supply unit to the high-voltage on-board electric grid is interrupted. Additionally or alternatively, the energy inflow of at least one other energy supply device is blocked, wherein the at least one other energy inflow is designed in order to supply energy from a further energy source to the high-voltage on-board electric grid.

An optical measurement system for measuring one or more portions of an object such as a vehicle and solving the issues relating to attitude of vehicle while measuring the one or more portions of the vehicle, is disclosed. The optical measurement system comprising a diagnostic, measurement and repair equipment arranged on the object for example a vehicle via a rigid linking structure. The system comprises a measuring head and one or more targets comprising one or more set of photodiodes. The measuring head is mounted under or on the vehicle. The system is configured to measure parameters representative of the vehicle. The device further comprises a computing device in communication with the equipment, comprising set of instructions to determine a position of the target regarding to a reference point. The location of the point is then compared to an original location of the point to determine the damage in the vehicle.

Disclosed is a bushing assembly height checking fixture, which is composed of a jacket, set screws, a measuring cylinder and a positioning cylinder. When the bushing assembly height checking fixture is used, the lower cone of the positioning cylinder is fitted with the orifice edge of an inner shaft hole of a bushing, and the checking fixture is positioned radially; the bottom surface of the jacket is flush with the assembly positioning end face of a workpiece, and the checking fixture is positioned axially; then the bottom surface of the measuring cylinder is flush with the end face of the bushing, the position of the top surface of the measuring cylinder is observed, and if the top surface of the measuring cylinder is in the middle of the top step of the jacket, it shows that the height after the workpiece is assembled is qualified.

A component, in particular a body component, for a vehicle, has at least one test section which is arranged in a predetermined area of the component and which is connected in one piece to the rest of the component by way of at least one connecting element. The connecting element is embodied as predetermined breaking point.

A wheel nut engagement checking system for a vehicle delivered by a conveyor includes: a moving member disposed at one side of the conveyor; a wheel lifting apparatus disposed on the moving member, and lifting a wheel of the vehicle from the conveyor to a predetermined height; a wheel nut torque checking apparatus provided on an arm of a robot disposed on the moving member, engaging a nut runner to a wheel nut of the wheel, and checking an engage torque of the wheel nut by rotating the nut runner; and a controller controlling a speed of the moving member, lifting the wheel to the predetermined height using the wheel lifting apparatus, moving the wheel nut torque checking apparatus using the robot so as to engage the nut runner to the wheel nut, and detecting an engage torque of the wheel nut by rotating the nut runner.

An embodiment system for adjusting a gap step includes a process device configured to mount a first moving part and a second moving part, a first information obtaining device including a camera, and a control device configured to control the process device based on a first driving control value such that the first moving part and the second moving part are mounted on a first vehicle body, obtain a first image of the first vehicle body on which the first moving part and the second moving part are mounted, obtain the gap step for the first moving part, the second moving part, or both through the first image, and mount the first moving part and the second moving part on a second vehicle body by controlling the process device based on a second driving control value corresponding to the gap step.

An electric vehicle includes a switching unit which is capable of performing switching between a permission state in which an electric motor is permitted to operate and an inhibiting state in which the electric motor is inhibited from operating. An assembling management system of the electric vehicle includes an information obtaining section which obtains set information set in a vehicle body or a battery and transmits the obtained set information to a determiner section which determines whether or not the electric motor is permitted to operate based on the set information, and an output section which receives a result of determination from the determiner section, and outputs an electric signal indicating which of a permission state and an inhibiting state should be set in the switching unit.

Provided are a system and method for measuring a vehicle gap or step, where a vehicle body to which a hood, a door, and a trunk lid are assembled is seated on a carrier and moved along transfer lines. The system may be installed over the transfer lines and may include one or more door regulating units attached between the vehicle body and the door, upper rails in both sides above a workplace corresponding to the transfer lines, a moving frame movable below the upper rails, a forward/backward moving unit above the moving frame, a horizontal moving unit to move installation frames, a vertical moving unit in the installation frames to reciprocally move a sliding plate upwardly and downwardly, a measurement module movable and rotatable to measure the gap or the step, and an electronic tag on a roof of the vehicle body.
