NS. In the axis adjustment work, the orientation of the object detection device is adjusted so that the radiant wave or the axial direction of the optical axis of these vehicle object detection devices faces an appropriate direction with respect to the vehicle 61.

In the calibration work management system 100, the calibration work auxiliary device 10 functions as a system management server and assists the worker of the certified factory 60 to properly perform the axis adjustment work of the object detection device. When the requester 3 for the axis adjustment work of the object detection device mounted on the vehicle 61 transmits the application for the work request to the calibration work auxiliary device 10, the calibration work auxiliary device 10 notifies the certified factory 60 of the work request. The workers of the certified factory 60 who received the notification of the work request carry out the axis adjustment work according to the contents of the request.

When the axis adjustment work is completed, the worker transmits data such as work contents and work conditions to the calibration work assisting device 10. The calibration work assisting device 10 generates a work report based on the received data and stores the data of the work report. The proofreading work assisting device 10 may lock the data of the work report stored in the database so as not to be rewritable. Further, the calibration work assisting device 10 issues a work certificate certifying that the axis adjustment work has been performed properly, and notifies the requester 3 and the system administrator 1 of the completion of the work. The client 3, the certified factory 60, and the system administrator 1 can appropriately browse the work report stored in the database.

The calibration work assisting device 10 presents the setting information for setting the work environment for performing the shaft adjustment work to the certified factory 60 so that the shaft adjusting work is appropriately performed in the certified factory 60. The setting information is set based on the information of the target vehicle 61 for performing the axis adjustment work and the work environment data of the certified factory 60 registered in advance.

A2: Height difference and levelness of work pit A3: Insolation condition of direct sunlight and work illuminance A4: Ability to perform axis adjustment work

Condition A1 defines the minimum size of the work pit required to carry out the axis adjustment work of at least one type of object detection device. Specifically, condition A1 defines the minimum dimensions of each of the frontage and the depth.

Condition A2 stipulates that the installation surface of the four wheels of the vehicle 61 and the installation surface of the work assisting tool can be set to a horizontal plane by using a shim for height adjustment. For example, condition A2 stipulates that the height difference between each installation surface is within 10 mm, the horizontal angle of each installation surface is ± 0.5 ° or less, and the flatness of all installation surfaces is 1 ° or less. do.

Condition A3 defines the permissible range of the difference in brightness or light and darkness that occurs during the axis adjustment work.

A length that can secure a distance B to the reflecting surface and a stopping space C capable of stopping one or more kinds of vehicles 61 to be targeted is required. Assuming that a plurality of different types of object detection devices are mounted on the vehicle 61, the depth L required for the work pit 30 is defined based on the object detection device that requires the largest depth. Although not shown, a similar space is required for the axis adjustment work of the object detection device that detects an object on the side or the rear of the vehicle 61, and the frontage W of the work pit 30 is defined.

Further, the floor surface F of the work pit 30 is required to have at least a horizontal flat surface between the installation surface of the four wheels of the vehicle 61 and the installation surface of the reflector 33. In this condition, the floor surface F itself may be a horizontal flat surface, or the installation surface of the reflector 33 may be made to match the installation surface of the four wheels of the vehicle 61 by using a height adjusting shim.

For example, when the height of the four-wheel installation surface of the vehicle 61 and the height of the reflector 33 installation surface of the floor surface F of the work pit 30 are different, the height of the shim for matching the two is specified. If multiple shims with different heights are prepared, the height of the shims to be selected can be specified, and if shims of a certain height are prepared, the number of shims to be used can be specified. Often, these may be combined. Such setting information can be determined based on the information on the height of the floor surface F of the work pit 30 in the work environment data.

Further, the work request processing unit 21 may simultaneously send a work completion report message to the system administrator 1.

The requester 3 or the system administrator 1 who has received the work completion report message can check the work contents and the work results at any time by accessing the work report data stored in the database 15. The work report data stored in the database 15 may be associated with the identification data of the requester 3 to limit the users who can access the work report data.

As described above, according to the calibration work management system 100 provided with the calibration work auxiliary device 10 according to the present embodiment, since the work environment data of each certified factory 60 is registered, it is the target of the axis adjustment work. It is possible to provide setting information for preparing a working environment according to the vehicle 61. For this reason, it is possible to accurately carry out the axis adjustment work, which conventionally requires high technology, experience, and time, in a short time. Further, since the data of the work report certifying that the highly accurate axis adjustment work has been performed can be saved, the reliability of the vehicle 61 equipped with the object detection device can be improved.

Although the preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, the present invention is not limited to such examples. It is clear that a person having ordinary knowledge in the field of technology to which the present invention belongs can come up with various modifications or modifications within the scope of the technical ideas described in the claims. , These are also naturally understood to belong to the technical scope of the present invention.
