As described above, the controller A, which operates the electric device in time in a conventional commercial vehicle, is provided in the cluster 6 for a predetermined time when the seat belt is not detected from the seat belt switch 1 at the initial engine startup. The cluster 6 is provided with an operating time of the heater relay 4 which turns on the seat belt warning lamp to induce the driver to wear the seat belt and analyzes the signal of the water temperature sensor 3 during cold start and heats the glow plug. The preheating lamps enable the operator to securely prepare for start-up and engine maneuverability during cold start.

In addition, when spraying the washer fluid or the intermittent wiper operation using the multifunction switch 5 is selected during driving in the rain, the controller A controls the washer motor and the wiper relay 7 according to the delay time for the selected signal. Intermittent wiper drive and washer fluid injection.

As described above, in the case of a controller for controlling the operation of a temporal electric device in a conventional commercial vehicle, a detection sensor, a switch device, and a driving device, etc. installed in each part of the vehicle are connected by complicated wire electric wiring, which makes it difficult to design the electric wire Increasing the production cost due to the consumption of a lot of wires, there is a problem that is difficult to find and recover the faulty part due to the wiring of the complex wire if a disconnection or short circuit occurs in any part of the wire.

In addition, since the detection of each detection sensor, a switch device and a driving device must be taken into account when changing the design of the electric field according to the development of the vehicle, a disadvantage arises that a lot of restrictions are involved in the design.

The present invention has been invented to solve the above problems, the object is to transmit the signals of each sensor and the drive selection switch provided in the commercial vehicle to the corresponding drive device and the indicating device side in a network manner through the communication module It eliminates the installation of complex wired wires in the vehicle, enables quick response when the vehicle design and specifications are changed, and eliminates the complicated wired wires to reduce the manufacturing cost of the vehicle and provide convenience to the manufacturing process. .

The present invention for realizing the above object is a sensor module for collecting and transmitting information of each sensor and driving device provided in the vehicle, a module for collecting and transmitting information of each switch selected by the driver, and transmitting from each module And a cluster module for collectively collecting the information to indicate the information and to perform the operation of the device.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As can be seen in Figure 1, the control device using a network in a commercial vehicle according to the present invention is a sensor module 30 connected to a sensor requiring a time operation instruction, such as a coolant level sensor, a water temperature sensor, a heater relay, and multi-function The multi-function module 50 connected to the switch 40, the seat belt switch 10, the sensor module 30, the multi-function module 50, the wiper and the washer module 70 are connected to a network to provide a temporal indication. It consists of a cluster module 60 that performs alerts and temporal actions.

Each of the sensor modules is connected to a network, and each of the sensor modules includes a CPU, which is a control means capable of implementing a unique function assigned to the sensor module.

The cluster module 60, which aggregates the signals of the respective sensor modules, provides the driver with various indication and display means provided in the cluster 90, and receives temporal indication information connected to the cluster 90 through a wire. .

And output to the warning means to induce the driver to wear the seat belt.

In addition, when the driver triggers the ignition key for starting in the cold state, since the water temperature sensor and the heater relay signal for driving the preheat heater are detected by the sensor module 30, the CPU in the sensor module 30 sets the detected signal. It is formalized in logic and transmitted to the cluster module 60 through the network.

At this time, the cluster module 60 analyzes the signal of the sensor module 30 transmitted through the network and then instructs the engine starting condition through the indicating means provided in the cluster 90 according to the set logic.

The CPU in the multifunction module 50 formats the detected signal into the set logic and transmits the detected signal to the cluster module 60 through the network.

At this time, the cluster module 60 transmits a signal for intermittent wiper driving or washer fluid injection to the wiper and washer module 70 through the network, and the CPU in the wiper and washer module 70 sets the received signal. By driving the wiper relay and the washer motor 80 connected to the wire at a time interval according to the logic to perform the injection of the washer liquid or the intermittent wiper operation.

In the above description, the connection of the network is described only for the timed operation. However, all the electrical / electronic devices provided in the commercial vehicle may be connected to the network by providing the sensor module at each position.
