An assembling method of an electric vehicle comprises the steps of: assembling a vehicle body including a frame, wheels and an electric motor; conducting a vehicle body test including confirmation of a state of driving power transmission from the electric motor to the wheels by connecting an electric power supply unit installed in a vehicle body test place to the electric motor of the vehicle body and supplying electric power from the electric power supply unit to the electric motor; detaching the electric power supply unit from the electric motor and transporting the vehicle body which has passed the vehicle body test from the vehicle body test place to a mounting place, in a state in which a battery is not mounted to the vehicle body; and mounting the battery to the transported vehicle body in the mounting place.

A quality management apparatus includes an acquisition unit and an extraction unit. The acquisition unit acquires, about products to be managed, a rate of occurrence of a malfunction on an occurrence period basis, an operation condition of the products, and a manufacturing condition for the products. The extraction unit classifies the rate of occurrence into layers under the operation condition, and extracts, for each layer under the operation condition, a relationship between the rate of occurrence and the manufacturing condition.

A method of assembling vehicle parts, the method including: measuring at least one of a dimension or a characteristic of each of plural types of vehicle parts, and, for types of vehicle parts of which there are plural in stock, measuring at least one of a dimension or a characteristic of each one of the plural vehicle parts that are in stock; determining a combination of the plural types of vehicle parts by selecting specific vehicle parts from among the types of vehicle parts of which there are plural in stock, such that the selected specific vehicle parts closely approximate specific vehicle specification reference values; and assembling the plural types of vehicle parts in accordance with the combination that has been determined.

A method of producing a deflector device for a fuel tank system comprising producing a deflector device prototype from prefabricated components of a construction kit, performing fuel-refilling tests using the deflector device prototype, optionally modifying the deflector device prototype, creating a construction model for the deflector device prototype, producing a deflector device according to the construction model, optionally performing fuel-refilling tests with the deflector device produced according to the construction model and optionally producing the deflector device according to the construction model. The disclosure further provides a construction kit with prefabricated components for producing the prototype of the deflector device for the fuel tank system.

An embodiment parallel cell based mobility production system includes a serial production line through which vehicles of various types sequentially pass to be processed, a parallel production line composed of a plurality of sublines arranged in parallel, each subline provided with a plurality of cells arranged in serials, and an inspection line in which the vehicles of various types passed through the parallel production line are sequentially fed.

A method of manufacturing a modular vehicle subassembly (MVS) includes assembling a propulsion system onto a vehicle frame, assembling a suspension system onto the vehicle frame, assembling a steering system and braking system onto the vehicle frame, assembling an electrical distribution system onto the vehicle frame, and integrating an onboard controller with the propulsion system, the steering system, and the braking system. The onboard controller is configured to command the propulsion system, the steering system, and the braking system such that the MVS is operable to move untethered through a top hat assembly line during assembly of a top hat on the MVS.

A vehicle inspection method in a production line of a vehicle includes: performing a part inspection in steps of manufacturing parts of the vehicle, the part inspection in which each of the parts after being manufactured is inspected with an inspection device and which includes one or more inspection items; storing a result of the part inspection in a storage device such that the result is associated with the part; and displaying the result of the part inspection, on a display device used in a completed vehicle inspection for inspecting a completed vehicle serving as the vehicle that is completed, information indicating at least the part of the parts corresponding to a failed item serving as the inspection item which is determined not to be passed in the result of the part inspection stored in the storage device and information indicating the failed item.

A method for producing an assembly is provided such that manufacturing defects and redundant work steps are preventively avoided.

A system for automatic wheel alignment adjustment of a vehicle in an inspection line is provided. The system is disposed under a mounting table mounted with a vehicle and includes a front wheel adjustment apparatus disposed in correspondence with a front wheel of the vehicle and configured to adjust alignment of the front wheel by adjusting a tie-rod and a lock-nut employed in a linkage structure of the front wheel, a rear wheel moving apparatus disposed in correspondence with a rear wheel of the vehicle and slidable in a vehicle width direction, and a rear wheel adjustment apparatus disposed in correspondence with the rear wheel of the vehicle, connectable to the rear wheel moving apparatus, and configured to adjust alignment of the rear wheel by adjusting a cam-bolt and a cam-nut employed in a linkage structure of the rear wheel.
