[0002]

2. Description of the Related Art In a vehicle production system, a plurality of components are assembled into a unit to perform a required function, and then the unit is combined with a predetermined electronic control unit to produce a vehicle device. Is conventionally performed. For example, in the case of a common rail type diesel engine device, these components are mechanically integrated by assembling a common rail and a high pressure pump after mounting injectors for the number of cylinders on the diesel engine main body, and then integrating the engine unit. And an electronic control unit to produce electronically controlled diesel engine equipment.

[0003] The combination of the engine unit and the electronic control unit may be implemented on the same production line or in another production line. However, in any case, when the actual characteristics of the components constituting the engine unit deviate from the predetermined characteristics in the design (the central specification characteristics), the electronic control unit cannot operate the engine unit with the required characteristics. Occurs.

Therefore, conventionally, an identification pattern having correction information in each of the injectors is formed, written as control data in a corresponding electronic control unit, and required based on the characteristics of the actually assembled components. The control is performed electronically (see, for example, JP-A-2001-336644).

FIGS. 1 to 6 are process diagrams for explaining an example of an embodiment in which the present invention is applied to a vehicle production system using a common rail type diesel engine as a drive source. In this embodiment, an injector, a common rail, a high-pressure pump, and various sensors are assembled to a diesel engine main body, and these are mechanically integrated to assemble a common rail type diesel engine unit. An example will be described in which an electronic control unit for electronically controlling a diesel engine unit is attached to a predetermined location in a vehicle after being attached to a vehicle production system. However, the present invention can be applied to all kinds of vehicle production systems other than the one embodiment, such as a vehicle air conditioner, a vehicle automatic transmission, and a vehicle brake device.

FIG. 1 is a process diagram for explaining a process when assembling the injectors 21 to 24 to the diesel engine main body 1. On the surface of each of the connector sections 21A, 22A, 23A, and 24A of the injectors 21 to 24, a recording section that records a code representing the characteristic of the corresponding injector so as to be optically readable is provided. The recording unit may be either integral with or separate from the injector. This code makes it possible to know what the actual characteristics of the corresponding injector are and can be made based on the characteristics actually measured using the injector. The code content can be a content that directly indicates the actual characteristic itself. But,
Alternatively or additionally, the code may indicate the difference between the actual characteristic and the design characteristic. The code may be any combination of symbols, numbers, letters, etc., a bar code, or any other code in a known and appropriate form.

In order to provide a recording section in which such a code is recorded in the injector, a required code may be directly printed and engraved on an appropriate place of the injector and provided integrally. Alternatively, a required code is printed, for example, on a plate or sheet made of an appropriate material such as paper, plastic, metal, or the like, and the obtained plate, sheet, or the like is bonded to the surface of the injector, welded, or other appropriate means. It can also be provided as a separate body by attaching it. Alternatively, the recording unit may be suspended from a tag.

In the present embodiment, a required code is printed on a plastic sheet and the surface thereof is coated as a characteristic code sheet, which is a recording section. Characteristic code sheets 21a to 24a indicating the respective characteristics are attached to the connector portions 21A to 24A, respectively. The same applies to other characteristic code sheets described later.

After the injectors 21 to 24 are mounted on the mounting holes 11 to 14 provided in the diesel engine main body 1, each characteristic code sheet 21a is read by the code reader R.

In this embodiment, the contents of the characteristic code sheets 21a to 24a are combined into one sheet, and this is obtained as another code sheet S1. Another code sheet S <b> 1 is attached to a position where the upper surface 1 </ b> A of the diesel engine main body 1 is easily seen.

The production of another code sheet S1 may be performed before the injectors 21 to 24 are attached to the diesel engine main body 1, or the characteristic code sheets 21a to 2 may be produced.
Another code sheet may be created one by one for each reading of 4a, and may be four sheets.

Is fixed on the upper surface 1A using a known appropriate mounting member. Thereafter, the content of the characteristic code sheet 31a is read by the code reader R, and another code sheet S2 is created. The content of another code sheet S2 is the same as the read content of the characteristic code sheet 31a. Another code sheet S2 is attached on the upper surface 1A and near the other code sheet S1.

It is needless to say that another code sheet S2 may be prepared before the common rail 3 is attached.

FIG. 3 shows the injector 2 as described above.
FIG. 3 is a diagram for explaining a process of attaching the high-pressure pump 4 to the diesel engine main body 1 after the attachment of the common rails 1 to 24 is completed. End face 4 of high-pressure pump 4

The high-pressure pump 4 is arranged and fixed at the end of the diesel engine main body 1. Thereafter, the content of the characteristic code sheet 4a is read by the code reader R, and another code sheet S3 is created. The content of another code sheet S3 is the same as the read content of the characteristic code sheet 4a.
Another code sheet S3 is attached on the upper surface 1A and near the other code sheets S1 and S2.

It is needless to say that another code sheet S2 may be prepared before the high-pressure pump 4 is attached.
