The vehicle has a function to control the rotation speed of the wiper according to the vehicle speed in relation to the wiper control, the rain sensor detects the rain sensor to operate the wiper when it rains, and the rain or snow falling to the headlamp lens by driving the wiper blades left and right. There is a head lamp washer device that secures the front field of vision at night by wiping.

It provides CAN (Controller Area Networks) communication that can control the data exchange and priority of various data between the central controller and sub-controllers installed in the vehicle, and is a kind of device dedicated to troubleshooting A Hi-Scan device is provided.

In recent years, in pursuit of the convenience of the driver, a keyless entry system that allows a driver to remotely control electric devices such as a door lock device and a starter device by operating a key having a remote control function has been widely applied.

In particular, by adding a panic function to a key having a remote control function to make an emergency sound, the position of the vehicle can be found.

In addition, defrost timers, power window timers, room & foot lamps and keyhole lighting for timer-related controls, seat belt reminders for chime control, key operation warnings And overspeed warning function.

In addition, lamps having various functions such as tail lamps, head lamps, front and rear fog lamps, and auto lighting are provided.

As described above, the vehicle is provided with various convenience devices for providing convenience to the occupant. Such a convenience device is usually appropriately controlled by a body control module (BCM) installed inside the vehicle.

However, as the demand of consumers for convenience devices in vehicles increases as described above, the control functions of the BCM are increased, and the software is complicated.

For this reason, many electronic control units (ECU: Electronic Control Units) are equipped and controlled by CAN communication in automobiles, and automotive module manufacturers are also using serial communication modules (ECU). Doors, trunks, side mirrors, seats, etc.), and these manufacturers perform a function test before delivery. It is a situation that the test is performed through the equipment, and the information of the functional test cannot be put into the upper systems MES, POP, and ERP, and it also has the inconvenience of having to perform the inspection manually.

In order to solve these shortcomings, the present invention can communicate with each ECU (Electronic Control Unit) of the module in the component test process of an automobile module manufacturer, and deliver an operation message indicated from the CFU control panel and test its function. Even though different protocols are specified for each car vendor and vehicle type in CAN communication, the various protocols are analyzed and embedded in the CFU, and the newly released models and protocols used by new vendors are embedded in the CFU. It has the purpose to provide CFU, a control device that can be easily responded with minimum cost and time by updating, and provides real-time monitoring of test information collected from CFU, and implements the result data as a file system. It can be run stand alone, Storage rules of the file system for the same is configured to normalize, such data storage rules to public, there is still another object to yitorok for the upper linkage as MES and the ERP system.

The present invention provides a body communication module (BCM) constituting a vehicle component module, an electronic control unit (ECU) for controlling the body control module (BCM), and CAN communication for organically connecting the electronic control unit (ECU). In the control system for controlling the

The CAN communication function test unit (CFU) is provided between the control panel to guide the operation of the electronic control unit (ECU).

The data of the CAN communication function test unit includes a communication function field with each electronic control unit (ECU), a control panel control command data receiving function field, a CAN protocol field for vehicle module control, and an external interface field for storing monitoring and test results. Provided is a CAN communication control system for a vehicle body control module.

As described above, the present invention may be applied to a process inspection system of an automobile body control module (BCM) manufacturer, applied to a final process inspection system of a finished vehicle company, and may be provided in an add-in form to an automotive tester. It builds a business model base that can be applied to communication-based systems, secures manufacturing cost competitiveness by distributing CAN communication testers, and eliminates the cost of introducing products by eliminating functions that are not needed for process inspection among existing functions. It is possible to reduce the inconvenience of using the equipment by minimizing the user interface and minimizing the product.

It provides an interface that can utilize the data used in the test in various period systems (ERP, MES), which can help to make the most of the produced data.

The present invention provides a vehicle body control module (BCM) constituting a vehicle component module, an electronic control unit (ECU) for controlling the body control module (BCM), and the electronic control unit (ECU) to achieve the above object. In a control system for controlling CAN communication to organically connect the

CAN communication function test unit that analyzes CAN communication protocols by vehicle vendor and vehicle type, and performs CAN communication between body control module (BCM) and electronic control units (ECU) by vehicle module by analyzing analyzed protocols. CFU: CAN Function Unit (CFU), CFU control panel that receives the control function from the user, and CFU Monitoring System to monitor the test results of the CFU, and CAN communication function test unit (CFU: CAN Function Unit) In the parts test process of the company, it communicates with each ECU (Electronic Control Unit) of the module to transfer the operation message indicated from the CFU control panel and to test its function.The CFU control panel is designed to be tested by the user.
