Devices such as the vehicle starter 400 and the vehicle air conditioner 500 are controlled by one host device 200 using the system communication line 100.

  In the third embodiment, as shown in FIG. 5, the power generation device for vehicle # 1 (300a), which is the communication master vehicle power generation device, is directly connected to the system communication line 100 with the host device 200. The other one or a plurality of communication slave vehicle power generation devices (in FIG. 5, 300b which is the vehicle power generation device # 2 and 300c which is the vehicle power generation device # 3) are the communication master vehicle power generation devices. It is connected to the local communication line 110 from 300a.

  When the host device 200 controls the vehicle power generation devices 300a, 300b, and 300c, the communication master vehicle power generation device 300a transmits the message frame to the communication master vehicle power generation device 300a via the main communication line 100. The message frame from the host device 200 is converted to the local communication line 110 and the message frame is transmitted to the communication slave vehicle generators 300b and 300c.

  Thus, it is necessary to cause one vehicle power generation device to function as the communication master vehicle power generation device among the plurality of vehicle power generation devices, and to function the other vehicle power generation device as the communication slave vehicle power generation device, For example, a method of preparing a plurality of types of vehicle power generation devices in which the respective communication modes are fixed at the manufacturing stage is conceivable. In the third embodiment, one type of vehicle power generation device is a communication master vehicle power generation device. As a method for setting whether to function as a communication slave power generation device, the following method is used.

  That is, in FIG. 5, each vehicle power generation device 300a, 300b, 300c is connected to the Cm terminal as a main communication terminal connected to the system communication line 100 with the host device 200 and the communication master vehicle power generation device 300a. If a Cs terminal is provided as a local communication terminal and the Cm terminal is connected to the system communication line 100, that is, for example, if a communication carrier is detected at the Cm terminal, the Cs terminal is caused to function as a communication master vehicle power generator.

Let

  In this way, the communication master vehicle power generation device and the communication slave vehicle power generation device can be distinguished from each other by the communication signal input terminal. For example, when only a maximum of one communication slave vehicle power generation device is connected to the local communication line. It is sufficient that the communication master vehicle power generation device and the communication slave vehicle power generation device can be distinguished.

However, when a plurality of communication slave vehicle power generation devices 300b and 300c are connected to one local communication line 110 as shown in FIG. 5, device identification of the communication slave vehicle power generation devices is required.
In this case, as in the first embodiment, the communication slave device identification method is provided with the setting terminal Set, and the device identification of the communication slave vehicle power generation device can be performed by the potential level. It is also possible to set functions as a power generator for a vehicle and a power generator for a communication slave vehicle.

  As described above, according to the third embodiment, a single vehicle includes a plurality of vehicle power generation devices, and a power generation control command for the plurality of vehicle power generation devices from the host device via the communication interface, In the control method of the vehicle power generation system that reports the status from the vehicle power generation device to the host device, one of the plurality of vehicle power generation devices is directly connected to the system communication line between the host devices, As a communication master vehicle power generation device, other vehicle power generation devices are not directly connected to the system communication line with the host device, but are connected to a local communication line via the communication master vehicle power generation device, By setting it as the communication slave vehicle power generation device, all vehicle power generation devices can be efficiently controlled from the host device without requiring a new communication ID.

Embodiment 4 FIG.
FIG. 6 is a block diagram for illustrating a control method for a vehicle power generation system according to Embodiment 4 of the present invention, and a plurality of, for example, three vehicle power generation devices 300a, 300b, and 300c, and other auxiliary machines. Devices such as the vehicle starter 400 and the vehicle air conditioner 500 are controlled by one host device 200 using the system communication line 100.

  In the fourth embodiment, a Cm terminal as a main communication terminal connected to each vehicle power generation device 300a, 300b, 300c and the system communication line 100 with the host device 200 and a communication master vehicle power generation device 300a are connected. Device identification as a communication slave vehicle power generation device by providing Cs1 and Cs2 terminals as two local communication terminals and inputting a communication signal from the communication master power generation device 300a from different terminals Cs1 or Cs2, respectively. Can be determined.

For example, in the vehicle power generation system of FIG. 6, by detecting a communication carrier at the Cm terminal and detecting a carrier at the Cs1 terminal, it comes to respond to the communication ID as the second vehicle power generation device, Alternatively, by detecting a communication carrier at the Cs2 terminal, it responds to the communication ID as the third vehicle power generation device.
However, according to the configuration of FIG. 6, the communication master vehicle power generation device 300a and the communication slave vehicle power generation devices 300b and 300c are connected by the one-to-one local communication line 110, so that each vehicle power generation There is no need to distinguish the communication slave vehicle power generation device unless the operation setting is individually performed for the device.
By doing in this way, since the operation mode of each vehicle power generation device can be set, there is no omission of setting, and the operation mode can be switched using one type of general-purpose model.

  As described above, according to the fourth embodiment, the main communication terminal connected to the system communication line and the local communication terminal connected via the local communication line have a communication signal from the main communication terminal. The received vehicle power generation device automatically operates as the communication master vehicle power generation device, and the vehicle power generation device that has received the communication signal from the local communication terminal automatically functions as the communication slave vehicle power generation device. The vehicular power generation device that receives the communication signal from the main communication terminal that connects the system communication line from the functioning host device automatically operates as the master vehicular power generation device, so that the vehicular power generation device and the slave that perform master operation The operating vehicle generator can be the same model, and the master and slave vehicle generator can be It is connected me is eliminated.

Embodiment 5 FIG.
For example, the system communication line 100 in FIG. 6 is determined by the communication specification of the host device, but the local communication line 110 is connected to the communication master vehicle power generation device 300a because the local communication line 110 is connected to the communication master vehicle power generation device 300a as described above. The communication protocol can be converted, and the implementation circuit can be simplified by making the local communication line the same communication protocol as the system communication line.

FIGS. 7 to 10 show a control method for the vehicle power generation system according to Embodiment 5 of the present invention, and are explanatory diagrams showing the operations of the communication master vehicle power generation device and the communication slave vehicle power generation device in FIG. is there.
FIG. 7 shows the operation of the communication master vehicle power generation device when a command message frame for setting the operation is transmitted from the host device to the vehicle power generation device.
A message frame composed of, for example, a synchronization flag, ID, command content, and error test is transmitted from the host device to the system communication line.

  The communication master vehicle power generation device 300a does not change the contents of the message frame input from the Cm terminal to which the system communication line is connected to the local communication line connected to the Cs1 terminal or the Cs2 terminal. The signal is transmitted through, and the start position of the frame is detected by the synchronization flag in the message frame, and the message frame is recognized as a command by the ID sent from the host device.

When the communication master vehicle power generation device 300a recognizes that the message frame is a command based on the ID sent from the host device, the command master and the error verification are connected to the local communication line connected to the Cs1 terminal or the Cs2 terminal. The contents of the message frame on the system communication line inputted from the terminal are transmitted through, and the command contents are temporarily buffered by S / P (serial / parallel) conversion, for example, and the system communication circuit inputted from the Cm terminal is temporarily buffered. The message frame on the line is successfully received.
As a result, the communication master vehicle power generation device 300a performs setting according to the buffered contents, and starts operation with the changed contents.

  In this way, by using a communication protocol similar to that of the system communication line for the local communication line, the communication signal to the local communication line can use the message frame of the system communication line as it is. The device does not require a special circuit as an interface with the local communication line.

FIG. 8 shows operations in the communication slave vehicle power generation devices 300b and 300c when the command message frame for setting the operation is transmitted from the communication master vehicle power generation device 300a.
As described above, a message frame composed of, for example, a synchronization flag, an ID, a command content, and an error test is transmitted to the local communication line from the host device via the communication master vehicle power generation device 300a. .

  When recognizing that the message frame is a command from the ID sent from the communication master vehicle power generation device 300a, the communication slave vehicle power generation devices 300b and 300c, for example, S / P-convert the command content and temporarily buffer the command contents. After the message frame on the local communication line inputted from the Cs1 terminal or the Cs2 terminal is normally received, the setting based on the buffered contents is performed, and the operation is started with the changed contents.

  In this way, by using the same communication protocol as the system communication line for the local communication line, the command analyzing part in the communication slave vehicle power generation device can use the same part as the communication master vehicle power generation device. Does not require a simple circuit.

FIG. 9 shows an operation in the communication master vehicle power generation device 300a when a response message frame for reporting a status is transmitted from the host device to each vehicle power generation device.
A message frame composed of, for example, a synchronization flag and an ID is transmitted from the host device to the system communication line.

  The communication master vehicle power generation device 300a does not change the contents of the message frame input from the Cm terminal to which the system communication line is connected to the local communication line connected to the Cs1 terminal or the Cs2 terminal. The signal is transmitted through, and the start position of the frame is detected by the synchronization flag in the message frame, and it is recognized that the message frame is a response from the ID sent from the host device.

  When the communication master vehicle power generation device 300a recognizes that the message frame is a response based on the ID sent from the host device, the data portion of the input signal of the Cs1 terminal and the Cs2 terminal connected to the local communication line is S. / P conversion to temporarily buffer the status report contents of the communication slave vehicle power generation devices 300b and 300c, and the status report content of the communication master vehicle power generation device 300a to the Cm terminal connected to the system bus, for example Status report contents of communication slave vehicle power generator connected to Cs1 terminal that performs transmission after P / S (parallel / serial) conversion and is temporarily buffered, communication slave vehicle power generator connected to Cs2 terminal Edit the status report contents of all and the status report contents of all vehicle power generators into one, and further communicate Reports to the higher-level device by adding the redundant bit sequence of the fixed and are error assayed by protocol.

  When the response message frame on the local communication line received by the communication master vehicle power generation device 300a cannot be received normally (when an error is detected as a result of error verification), the communication master vehicle power generation is performed. By transmitting inverted data of a normal bit string as a redundant bit string for error verification added by the device 300a, it is possible to recognize that there is an error in data received by the host device from the communication master vehicle power generator.

  As described above, the communication master vehicle power generation device 300a requires an interface circuit for receiving response messages from the communication slave vehicle power generation devices 300b and 300c, but is similar to the system communication line with respect to the local communication line. By using this communication protocol, a circuit block for receiving a command message at the Cm terminal can be used, so that no special design is required.

FIG. 10 shows operations in communication slave vehicle power generation devices 300b and 300c when a response message frame for reporting a state is transmitted from communication master vehicle power generation device 300a.
As described above, for example, a synchronization flag and an ID are transmitted to the local communication line from the host device via the communication master vehicle power generation device 300a on the local communication line.
When it is recognized that the message frame is a response from the ID sent from the communication master vehicle power generation device 300a, the communication slave vehicle power generation devices 300b and 300c are connected to the communication terminal connected to the communication master vehicle power generation device. The status report content is transmitted after P / S conversion, for example, and a redundant bit string for error verification determined by the communication protocol is added and reported to the communication master vehicle power generator.

  In this way, by using the same communication protocol as that of the system communication line for the local communication line, the same part as the communication master vehicle power generation device can be used for the state reporting by the communication slave vehicle power generation device. Therefore, no special circuit is required.

  As described above, according to the fifth embodiment, the communication frame from the host device is sent as it is to the local communication line, so that no special circuit is required for the interface with the local communication line, and the local communication line By using the same communication protocol as the system communication line, it becomes possible to efficiently control all the vehicle power generators from the host device with a small number of additional circuits.
