A truck for examination of a vehicle body includes a moving module configured to move truck bases with a vehicle body fixed thereto, a sensor module configured to be moved by the moving module and to measure stop position distribution of the truck base that reaches a predetermined position, and a calibration module configured to adjust a position of the truck base based on the measured distribution. The examination truck may enhance reliability of measurement result of assembly precision in a system for measuring the assembly precision of the vehicle body in a vehicle body assembly line.

A hole detection method of a vehicle and a system performing the same may include positioning an air injection nozzle at a predetermined position of a vehicle body and positioning a sound sensor at a position corresponding to the air injection nozzle, injecting an air jet from the air injection nozzle, detecting a sound wave from the sound sensor, and calculating a characteristic of a water leakage hole formed on the vehicle body by using the sound wave detected from the sound sensor.

A test management module includes a test manager writing a test list, a first emulator controlling an operation of the vehicle according to instruction of the test manager, and a controller controlling an operation of a test station according to instruction of the test manager. The test list includes an event condition to be generated in a vehicle and operation information of the operation of the vehicle, which is performed when the event condition is satisfied, and the operation of the test station provided to virtually test the vehicle.

An image clearly displaying a work machine is easily obtained. A posture data generation unit estimates a posture of a work implement with respect to the body of the work machine in a captured image displaying the work machine. A motion state image generation unit creates a three-dimensional model representing a stereoscopic shape of the work machine based on the posture of the work implement. A specific viewpoint image generation unit creates image data including a two-dimensional image of the three-dimensional model, as viewed at a viewpoint position indicating a position of a viewpoint at which the three-dimensional model is virtually viewed.

A vehicle inspection device for implementing a test on automatic braking performance of a test vehicle including an optical laser device for obstacle detection, in an inspection room three sides of which are surrounded by side walls, the vehicle inspection device comprising: a test instrument disposed at a side of the test vehicle; and a mirror unit that covers an upper face of the test instrument and upwardly guides light emitted from the optical laser device. The mirror unit may include a combination of a first plane mirror part disposed horizontally and a second plane mirror part disposed to be inclined.

The present application relates to devices for determining inertia properties of an object, said devices comprising a support and a measuring platform which are arranged relative to each other in such a way that movements between two and five degrees of freedom are possible.

A method of controlling a Wi-Fi device in a vehicle, which includes determining, via a controller of the Wi-Fi device, an abnormal state of the vehicle; adding, via the controller, vendor specific data in a management frame to be transmitted to a different Wi-Fi device in a different vehicle via Wi-Fi Direct based on the determined abnormal state; transmitting, via a wireless communication unit of the Wi-Fi device, the generated vendor specific data to the different Wi-Fi device, wherein the management frame comprises at least one of a probe request frame, a probe response frame, a service request frame and a service response frame, and wherein the management frame is transmitted before an authenticated connection is established between the Wi-Fi device and the different Wi-Fi device.

A system for use in testing the installation of an airbag module in a vehicle is provided. The system includes a jig and an instrument coupled to the jig. The instrument includes a contact assembly and a linear actuator coupled to the contact assembly such that, when the contact assembly is seated adjacent to the airbag module, the contact assembly is selectively moveable towards the airbag module relative to the jig via the linear actuator for testing the installation of the airbag module.
