In the case of d, it was necessary to prepare various kinds of electronic units 36 to 39 depending on the vehicle grade and the combination of the options 34 and 35, which was costly and difficult to manage.

[Problems to be solved by the device]

The present invention has been made in view of the above points, and an object thereof is to provide an electronic unit system that can easily cope with changes in vehicle grades and combinations of options and is advantageous in terms of cost and management.

[Means for solving the problem]

In order to achieve the above object, the present invention comprises a circuit for operating an electric component, a switch for the circuit, a signal line connecting the electric circuit and the switch, and a connector portion following the signal line. In an electronic unit system composed of a main electronic unit and a sub electronic unit having a connector section for connecting to the connector section and having an option operation sensor connected to the electric component, a plurality of the sub electronic units are respectively provided. A first connector portion which is the connector portion for connection, a common signal line having one end connected to the first connector portion, and a second connector portion connected to the other end of the common signal line. The operation sensor for each option is connected to the signal line, the first connector section of the first sub electronic unit is connected to the connector section of the main electronic unit, Connect the first connector portion of the second sub-electronic unit to the second connector portion of the knit, characterized in that the connectable to each other plurality of sub electronic units to each other.

[Action]

By appropriately combining a plurality of sub electronic units, desired optional specifications can be met. Here, the sub electronic units can be assembled in any order by the common connector.

〔Example〕

FIG. 1 shows an electronic unit system for a door lock as an embodiment of the present invention.

In the figure, A indicates a main electronic unit, a computer (controller) 2 and two control transistors 3 and 4 are arranged inside a case 1, and an output signal line 5 for locking and unlocking the computer 2 is provided. , 6 are connected to the transistors 3 and 4, respectively. Further, input / output connectors 7 and 8 are provided at both ends of the case 1, and the input side connector 7
Connect the lock and unlock circuits 10 and 11 from the door lock switch 9 on the driver side to the connector, and connect the output side connector 8
A connector 15 is connected to the circuits 15 and 16 leading to the lock / unlock relays 13 and 14 connected to the door lock motor 12. In the figure, 17 indicates a battery.

Further, on the side of the case 1, there is provided an optional female connector 19 to which the lock / unlock output signal lines 5 and 6, the battery 17 and the ground line 18 are connected.

Then, the sub electronic unit B is connected to the female connector 19 for options. The sub electronic unit B
The computer 21 is arranged inside the case 20, the vehicle speed sensor 22 is connected to the input side of the computer 21, and the lock and unlock signal lines 23 and 24 on the output side are connected via the common signal line 44 to the case. Terminals are connected to connectors 25 and 26 provided on both sides of 20. Where 25 is the male connector, 26
Is a female connector for connecting the male connector 25 to the optional female connector 19 of the main electronic unit A.

Further, C is a sub-electronic unit to which an optional keyless sensor 27 is connected, which has a built-in computer 28 similar to the above, and has lock and unlock signal lines 29, 3 on the output side.
0 is connected to the male and female connectors 32 and 33 on both sides of the case 31 through a common signal line 45. The male and female connector 3
Reference numerals 2 and 33 have the same shape as the connectors 25 and 26 of the vehicle speed sensor sub-electronic unit B, and similar common connectors are provided to other option sub-electronic units (not shown).

When connecting the connectors to each other, the plurality of sub electronic units B, C, ... May be combined in any order. Then, for example, in the case of providing three kinds of optional functions, in the conventional structure, a + b, a + c, a + b + c, a + d, a + b + d, a
While we had to set up seven types of electronic unit systems such as + c + d, a + b + c + d,
According to this embodiment, it is only necessary to set three types of sub electronic units B, C and D (D is not shown) for one main electronic unit A.

[Effect of device]

As described above, according to the present invention, various kinds of electronic unit systems can be formed by appropriately combining a plurality of sub electronic units, and many option settings can be easily accommodated. Further, it is not necessary to prepare the same number of electronic unit systems as the option setting as in the prior art, which is advantageous in terms of cost and management. Further, since the sub electronic units can be assembled in any order by the common connector, the degree of freedom in design can be improved. Moreover, since the types of the electronic units are reduced, the types of wire harnesses connected to the electronic units can be significantly reduced.
