Hereinafter, an example of an embodiment of an in-vehicle control system according to the present invention will be described with reference to the drawings.
FIG. 1 is a schematic configuration diagram showing a vehicle network system according to the present embodiment.

  As shown in FIG. 1, the in-vehicle control system 1 mainly includes a wire harness 11, a master ECU 12, various vehicle electrical equipment 13, an in-vehicle connector 14, and a connection member 15. In this in-vehicle control system 1, the master ECU 12 performs multiplexed communication using the in-vehicle connector 14 as a slave by a standard in-vehicle communication system such as LIN (Local Interconnect Network) or CXPI (Clock Extension Peripheral Interface). In these LIN and CXPI, 15 types of unique IDs can be set to distinguish each of the plurality of in-vehicle connectors 14 and the vehicle electrical equipment 13 that are slaves.

  The wire harness 11 is a bundle of electric wires based on three types of electric wires: a power line 23 as a trunk line, a communication line 25, and a GND (ground line) 27. The wire harness 11 is arranged in a vehicle and includes multiple communication lines of a vehicle network system. Note that the wire harness 11 is not limited to the three types of the power supply line 23, the communication line 25, and the GND 27, and it is needless to say that the wire harness 11 may include other electric wires such as signal lines.

  Master ECU12 is an electronic control unit (ECU: Electronic Control Unit) which controls each vehicle electrical equipment 13 as a main control apparatus, for example, is comprised from the microcomputer. The master ECU 12 is connected to one end side of the wire harness 11 that is a trunk line.

  The vehicle electrical equipment 13 is a variety of electrical equipment mounted on the vehicle, and is a main equipment that is commonly attached to the vehicle or an auxiliary equipment that is selectively retrofitted to the vehicle. Examples of main equipment include joint boxes, air conditioner units, engine control units, power window units, rear combination lamp units, and power seat units. Auxiliary equipment includes, for example, centralized door locks. -There are units and seat heater units. The vehicle electrical equipment 13 includes a connection connector 13a.

  FIG. 2 is a diagram showing an in-vehicle connector used in the in-vehicle control system 1 according to the present embodiment, in which FIG. 2 (a) is a partially broken perspective view of the in-vehicle connector, and FIG. 2 (b) is FIG. 2 (a). FIG. 2 (c) is a front view of the in-vehicle connector shown in FIG. 2 (a), and FIG. 2 (d) is shown in FIG. 2 (a). It is AA sectional drawing of a vehicle-mounted connector.

  As shown in FIG. 2, by connecting the in-vehicle connector 14 to the wire harness 11, the vehicle electrical equipment 13 under the in-vehicle connector 14 can be connected to the wire harness 11 to construct a network of the in-vehicle control system 1.

  The in-vehicle connector 14 has an insulating resin case 32 constituted by an upper case 30 and a lower case 31, and a pressure contact portion 33 and a circuit board 34 are accommodated in the case 32. For example, the press contact portion 33 is configured by standing up a plurality of press contact blades 35, and is connected to a predetermined circuit of the circuit board 34. The circuit board 34 is provided with a board mounting connector 36, and the connection member 15 is connected to the board mounting connector 36.

  A control function unit 37 is provided on the circuit board 34 disposed inside the in-vehicle connector 14. The control function unit 37 has a signal generation unit that communicates with the master ECU 12 via the communication line 25 and generates a control signal for controlling the operation of the subordinate vehicle electrical equipment 13. The control function unit 37 is an electronic control unit (ECU) that electronically controls the vehicle electrical equipment 13. For example, a microcomputer, a semiconductor fuse, a communication transceiver, and the like are mounted on a circuit board or a circuit body using a bus bar. It consists of

  The in-vehicle connector 14 sandwiches the power line 23, the communication line 25, and the GND 27 in the wire harness 11 between the upper case 30 and the lower case 31. It is press-connected. The in-vehicle connector 14 sandwiching the power supply line 23, the communication line 25, and the GND 27 in the wire harness 11 is fixed at an arbitrary position of the wire harness 11 by locking the upper case 30 and the lower case 31. That is, the connection between the wire harness 11 and the vehicle electrical equipment 13 is simply completed simply by attaching the in-vehicle connector 14 to an arbitrary position of the basic harness.

  FIG. 3 is a schematic configuration diagram of a part of the in-vehicle control system 1 according to the present embodiment. FIG. 4 is a perspective view of the connection member and the in-vehicle connector according to the present embodiment.

  As shown in FIGS. 3 and 4, the connection member 15 is a member that connects the in-vehicle connector 14 and the vehicle electrical equipment 13. The connection member 15 includes a connection line 41, a network side connector 42, and a device side connector 43. The network side connector 42 is a connector that is coupled and connected to the board mounted connector 36 of the in-vehicle connector 14, and is provided at one end of the connection line 41. The device-side connector 43 is a connector that is coupled and connected to the connection connector 13 a of the vehicle electrical device 13, and is provided at the other end of the connection line 41. The connection member 15 is connected to the wire harness 11 by connecting the network side connector 42 to the board mounting connector 36 of the in-vehicle connector 14 and connecting the device side connector 43 to the connection connector 13a of the vehicle electrical equipment 13. The vehicle-mounted connector 14 and the vehicle electrical equipment 13 are electrically connected, and the vehicle electrical equipment 13 can be controlled by the control function unit 37 of the vehicle-mounted connector 14.

  As shown in FIG. 3, an ID output unit 51 is provided inside the vehicle electrical device 13. In the example of FIG. 3, the ID output unit 51 includes a resistor R. The ID output unit 51 has a function for outputting ID (Identification Data) for distinguishing each vehicle electrical equipment 13 to which the master ECU 12 is connected under the network. Actually, the inherent electrical characteristics (resistance values in this example) of the electrical components constituting the ID output unit 51 are associated with the ID values.

  As shown in FIG. 3, the ID output unit 51 is electrically connected to the internal circuit of the in-vehicle connector 14 via the electric wires 41 a and 41 b in a state where the vehicle electrical equipment 13 is connected to the in-vehicle connector 14 with the connecting member 15. . In this state, the ID recognition unit 37 a provided inside the control function unit 37 can recognize the ID output from the ID output unit 51.

  In the example of FIG. 3, a resistor Rc having a specific resistance value rc is arranged inside the in-vehicle connector 14, and the resistor R and the resistor Rc of the ID output unit 51 are connected in series to divide the voltage. A circuit is formed. A constant DC power supply voltage Vcc (+5 [V]) is applied to one end of the voltage dividing circuit, and the other end of the voltage dividing circuit is grounded. The DC voltage Vid output from the voltage dividing circuit is input to the analog voltage input terminal of the ID recognition unit 37a. The DC voltage Vid is expressed by the following equation.

Vid = Vcc × rc / (r + rc)
r: resistance value of resistor R

  Therefore, the ID recognizing unit 37a can input the DC voltage Vid as a voltage corresponding to the unique electrical characteristics of the ID output unit 51, and assigns the DC voltage Vid to the vehicle electrical equipment 13 by comparing the DC voltage Vid with a predetermined threshold value. ID values can be recognized.

  When the master ECU 12 and the control function unit 37 in the in-vehicle connector 14 communicate, the control function unit 37 transmits the ID value of the vehicle electrical equipment 13 recognized by the ID recognition unit 37a. Therefore, the master ECU 12 can individually control and control the plurality of in-vehicle connectors 14 and the plurality of vehicle electrical devices 13 to be controlled.

  Even when a plurality of in-vehicle connectors 14 and a plurality of different types of vehicle electrical equipment 13 are connected under the control of the master ECU 12 as shown in FIG. 1, the in-vehicle connectors 14 and the connection members 15 have a common configuration. There is no need to add a special function other than the ID recognition unit 37a. By sharing the circuit configuration and operation, it is possible to reduce the number of types of parts and the part number, thereby realizing cost reduction.

  FIG. 5A, FIG. 5B, and FIG. 5C are electrical circuit diagrams illustrating configuration examples of main parts of the three types of vehicle electrical equipment 13A, 13B, and 13C.

  The vehicle electrical equipment 13A illustrated in FIG. 5A includes a load 52A configured by a light emitting diode (LED) and an ID output unit 51 configured by a resistor R. Further, each terminal of the load 52A and the resistor R is connected to each terminal in the connection connector 13a.

  Moreover, the vehicle electrical equipment 13B illustrated in FIG. 5B includes a load 52B configured by a lamp and an ID output unit 51 configured by a resistor R. Each terminal of the load 52B and the resistor R is connected to each terminal in the connection connector 13a. 5C includes a load 52C configured by an electric motor and an ID output unit 51 configured by a resistor R. Each terminal of the load 52C and the resistor R is connected to each terminal in the connection connector 13a.

  Since all of the vehicle electrical equipment 13A, 13B, and 13C have the same shape and configuration of the connection connector 13a, the vehicle electrical equipment 13A, 13B, and 13C can be connected.

  FIG. 6 is a diagram showing the resistor R constituting the ID output unit 51, and FIGS. 6A to 6C are perspective views of the resistor, respectively. As for the resistor R, for example, as shown in FIG. 6A, a tuning fork type resistor having leads 62 connected to both sides of the resistor 61, and a resistor on the substrate 63 as shown in FIG. 6B. A chip type resistor in which the body 64 and the lead 65 are mounted, or a card type in which the resistor 66 is covered with a resin case 67 and the lead 68 protrudes from the end of the case 67 as shown in FIG. A resistor or the like is used.

  When there is a possibility of changing the assignment of the ID value of each vehicle electrical equipment 13, the resistor R of the ID output unit 51 can be replaced as necessary. For example, when the socket for making the resistor R detachable is arranged in the case of the vehicle electrical equipment 13 and constructing a network of the system for the first time, or when adding a new vehicle electrical equipment 13, Replacement of the resistor R is performed as necessary so as not to cause competition with other vehicle electrical equipment 13.

  In the configuration example shown in FIG. 7, a socket 53 is arranged at a location exposed to the outside of the case of the vehicle electrical equipment 13, and the ID output unit 51 can be attached to the socket 53. According to the configuration example of FIG. 7, since the ID output unit 51 can be easily replaced without disassembling the case of the vehicle electrical equipment 13, the ID value changing operation is facilitated. It is also conceivable to arrange the ID output unit 51 at the connection connector 13a.

  As described above, according to the present embodiment, since each vehicle electrical device 13 includes the ID output unit 51, it is not necessary to provide an ID setting function on the in-vehicle connector 14 or the connection member 15 side. Therefore, it is possible to use the common in-vehicle connector 14 and the common connection member 15. As a result, the cost can be reduced by using the in-vehicle connector 14 and the connection member 15 in common, and a plurality of types of in-vehicle connectors 14 with different IDs are prepared, or the ID of each in-vehicle connector 14 is changed by software or wireless. Therefore, the construction of the network and the addition of the vehicle electrical equipment 13 can be facilitated. Moreover, since it is not necessary to provide a circuit space or a component mounting space for providing the in-vehicle connector 14 with an ID setting function, the in-vehicle connector 14 can be reduced in size and weight.

  In addition, since the ID output unit 51 associates specific electrical characteristics such as the resistance value of the electrical component with the ID value, the number of components, the configuration, the installation space, the cost, etc. necessary for outputting the ID value are minimized. It is possible to

  In addition, by connecting the ID output unit 51 on the vehicle electrical equipment 13 side and the resistor Rc on the in-vehicle connector 14 side to form a voltage dividing circuit, the ID recognition unit 37a can easily set the ID value due to the voltage difference. Become recognizable.

  Further, by configuring the resistor R of the ID output unit 51 so as to be detachable from the vehicle electrical equipment 13, it is easy to replace the resistor R, and when constructing a system network or new vehicle electrical equipment. ID value assignment when adding 13 is facilitated.

Next, a modification of the in-vehicle control system 1 will be described.
(Modification 1: System configuration change)
FIG. 8 is a block diagram showing a modified vehicle-mounted control system.

  In the in-vehicle control system 1 shown in FIG. 8, a plurality of master ECUs 12A, 12B, and 12C that perform independent control are prepared, the vehicle electrical equipment 13A is connected under the master ECU 12A, and the master ECU 12B is under control. The vehicle electrical equipment 13B is connected to the vehicle ECU 13C, and the vehicle electrical equipment 13C is connected to the master ECU 12C. The master ECU 12A and the vehicle electrical equipment 13A are connected by a connection member 15, the master ECU 12B and the vehicle electrical equipment 13B are connected by a connection member 15, and the master ECU 12C and the vehicle electrical equipment 13C are connected. The members 15 are connected.

  Each of the master ECUs 12A, 12B, and 12C includes an ID recognition unit 12a for recognizing the ID output by each vehicle electrical equipment 13. Each ID recognition part 12a is comprised by the microcomputer provided in ECU. Further, similarly to the circuit inside the in-vehicle connector 14 shown in FIG. 3, the resistor Rc is provided inside the master ECU 12A, 12B, and 12C.

  Therefore, each ID recognition part 12a is allocated to the corresponding vehicle electrical equipment 13 based on the voltage output from the voltage dividing circuit comprised by the resistor R in each vehicle electrical equipment 13, and the resistor Rc. ID values can be recognized. Each master ECU 12A, 12B, and 12C can reflect the ID value recognized by the ID recognition unit 12a in the control of the vehicle electrical equipment 13. For example, the type of load connected under the ID value can be distinguished, and the content of control can be changed to content suitable for the load.

(Modification 2: Change of ID output method)
In the configuration example shown in FIG. 3, a voltage dividing circuit is formed by the resistor R of the ID output unit 51 arranged on the vehicle electrical equipment 13 side and the resistor Rc on the in-vehicle connector 14 side. Various modifications are conceivable.

(2-1)
If a circuit for directly detecting the resistance value of the resistor R is built in the ID recognition unit 37a, the voltage dividing circuit becomes unnecessary, so that the resistor Rc can be omitted.

(2-2)
When an AC voltage is used as a voltage to be applied to the voltage dividing circuit, other electric components having a specific impedance at a specific frequency such as capacitors can be used instead of the resistors R and Rc.

(2-3)
It is also possible to replace one of the resistors R and Rc constituting the voltage dividing circuit with another electric component such as a capacitor. In that case, the application of the DC voltage to the voltage dividing circuit is switched on and off, and the difference in the transient response characteristics of the rising or falling voltage output from the voltage dividing circuit is detected. It becomes possible to recognize electrical characteristics, that is, ID values.
(2-4)
A modification of the in-vehicle control system shown in FIG. 3 is shown in FIG. In the configuration shown in FIG. 9, one end of the resistor Rc in the in-vehicle connector 14 is connected to the power supply line (Vcc) instead of the ground (GND). In addition, one end of the resistor R is connected to the ground in the vehicle electrical equipment 13. Therefore, it is not necessary to provide the electric wire (41b) for connecting with the power supply line (Vcc) in the connecting wire 41, and the number of electric wires can be reduced.

(Modification 3: Change of vehicle electrical equipment 13)
(3-1)
As for the vehicle electrical equipment 13A, 13B, and 13C shown in FIG. 5, it is assumed that the equipment includes a single load. For example, an ID output unit 51 is incorporated in an input device that incorporates a sensor or a switch. And it can also connect to the vehicle-mounted control system 1 as the vehicle electrical equipment 13. In addition, a plurality of types of elements such as loads, sensors, and switches may be built in the vehicle electrical equipment 13 or the number of built-in loads may be increased.

(3-2)
In the example shown in FIG. 3, only a single resistor R is arranged as the ID output unit 51, but a plurality of resistors that can be selectively used instead of the resistor R are arranged in the ID output unit 51. You may do it. In that case, one resistor can be selected by a method such as switching a plurality of resistors with a switch or cutting and switching a part of a circuit pattern connecting the plurality of resistors.

  In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimensions, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.
