Description

1322623 IX. Description of the Invention: [Technical Field] The present invention relates to a remote control system for a vehicle, and more particularly to an integrated diagnostic device for a remote control system for a vehicle. [Prior Art]

A car's remote control system consists of an antenna, a main controller, and a remote control. A master controller is coupled to the various devices of the vehicle and allows the user to perform a desired operation by transmitting a control signal corresponding to the signal transmitted by the remote control to an appropriate vehicle control device. The automotive device can be connected to a host controller directly or indirectly via an expander.

Although the car's remote control system is often installed at the factory, most of the car's remote control system is installed after the customer buys the car. The remote control system installed at the factory is usually only for the door opening/closing function. Recently, remote control systems installed at the factory have expanded their capabilities to import some devices. The method of installing and testing a car's remote control system after purchasing a car is not only very complicated but not standardized. This is because the car has different models, different remote control system types, and installation methods. Therefore, although the same remote control system is assembled in the same vehicle type, the installer's wiring or option setting method will be different. An optional remote control option is set by connecting a selectable programmer to a host controller. Before or after a vehicle is installed with the main controller, or after wiring is completed 5 1322623

After the plurality of car devices, the installer connects to a selectable programmer to set or change the selectable item. In general, the choice of programmer varies depending on the remote control system vendor. Therefore, the selectable item can only be set or changed using the selectable designer provided by the remote control system manufacturer, and cannot use other manufacturers' selectable programmers. In addition, because the remote control system of the same manufacturer's car has similar steps and methods for setting a plurality of selectable items of the model, the selectable programmer is usually very familiar with the installation of the product by the manufacturer. In use, the installer may be aware of the type of selectable item and select via a simple display member, such as via an LED. Therefore, the user is limited to this and must return to the same location where the remote control system was first installed, and the installer cannot service the remote control system of the car that he has not installed. In addition, the function of the conventional selectable programmer is only for confirming and changing the selectable item settings of the main controller, and it is not possible to check whether the item is correctly functioned by the remote control. Therefore, the connection between the selectable programmer and the main controller must be interrupted, and the remote control is used to check whether the operation is correct, and when the setting is determined to be inappropriate, the alternative programming must be interrupted. The connection between the device and the main controller changes the setting. This step is repeated to make each setting. SUMMARY OF THE INVENTION The present invention is to solve the problem of solving the above-mentioned problems of the prior art 6 1322623. SUMMARY OF THE INVENTION The object of the present invention is to make it easier to set, test, and diagnose a remote control system for a vehicle on a single diagnostic device by standardizing a remote control system of a vehicle. Another object of the present invention is to set the selectable item by modifying the user interface regardless of the type of the remote control system of the vehicle, which is a disadvantage of the conventional selection programmer.

Another object of the present invention is to test and diagnose the remote control, antenna module, shock sensor, remote call sensor, temperature sensor, and automotive battery voltage sensor, which were previously untestable. These and other features of the present invention will become more apparent from the written description of the appended claims. BRIEF DESCRIPTION OF THE DRAWINGS These and other features, aspects, and advantages of the present invention will become more apparent from the description and appended claims. In a preferred embodiment of the present invention, in order to achieve the above object, a diagnostic apparatus for diagnosing a remote control system of a vehicle having a main controller connected to at least one automobile device is provided.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The accompanying drawings and the detailed description are to be construed as a The spirit and scope of the invention can only be defined by the scope of the appended claims. Figure 1 shows a preferred embodiment of the invention. The diagnostic device 100 embodied in one embodiment of the present invention is electrically connected to a main controller 200, which is installed in a vehicle, and the diagnostic device 1 is selectively connected to an antenna module 30. 0. The main controller 200 is mounted in a vehicle and electrically connected to a plurality of car devices. The main controller 200 can be categorized according to the functions of the vehicle remote control system (e.g., remote launch, alarm, door open/close, and combinations thereof). The main controller 200 does not provide functions such as opening/closing the sunroof or opening 1322623

Off lighting can be controlled via an extended pipe expander. A car device can be one of the different sensor devices (eg, a door sensor, a travel travel sensor, a shock sensor, a remote call system (RPS) sensor, a temperature sensor, a battery voltage sensor, and others), an operational sensor (eg, , door actuators, window actuators, and others), or electronic devices (eg, alarms, lighting, and others). The automotive unit and a host controller 200 can be electrically connected via separate wiring and a bus or network connection compatible with automotive communication protocols such as CAN, LIN, J1939/8A, GM-LAN, byte flight', and FlexRay. All of the following "wiring" means connected via a separate electrical wiring and via a bus/network compatible with a particular protocol. A selectable item of the primary controller 200 sets the primary control The action of the device, and provide different selectable items in the basic settings, as shown in Figure 4. For example, whether to use the pulse to open and close the door lock, you can set the optional items in the main controller. The remote controller of the vehicle has its own selectable programmer through which the selection items of the main controller are set. The option setting data is stored in the main controller for The set selection is made to operate the main controller. In addition, the type of pipe expander used and the mode of operation (eg, pulse or blocking) can be set. Because the selectable items can be checked or not checked, such as As shown in Fig. 4, all of the selectable data of the main controller can be stored using only a few bytes. The main controller 200 executes via a vehicle owner. The antenna module 400 of the remote controller 300 receives a control signal and responds to the signal

The task of 1322623. The antenna module 300 is a device for controlling a control signal transmitted by the remote terminal or a response signal input by the controller 2000. The antenna module position, for example, on the instrument panel, is conveniently transmitted and connected to the main controller by means of a separate cable. The system is connected to the antenna module 300, in the first figure, However, if only the candidate item is diagnosed, the antenna module 300 can be set to 100. Basically, the diagnostic device 100 is connected to the device to set/change the selectable item, and to test whether the main controller 100 or the antenna module 300 is operating normally. Hereinafter, the diagnosis and operation will be described in detail. Fig. 2 is a view showing a preferred block diagram based on the present invention. The main controller connection portion 1 1 〇 and the antenna connection send a signal to the main controller 200 and the antenna finger. The main controller connection unit 110 can directly connect to the transmission/reception interface, and can be a bus bar/network adapter 200 when connected to a specific regulation roadway. The system is configured with a separate optional program. The energy is set via an antenna module connection terminal, and is received (one-way) by one external (selectable) to be sent (bidirectional) by the primary group usually installed on one and receiving radio waves, 200 . Although the controller 200 of the diagnostic main controller 200 or the setting does not have to be connected to the diagnostic main controller 200, the diagnostic device unit 1 for constituting the structural embodiment of the remote control device and the remote control device 400 is used. 7 0 respectively, the receiving group 300 receives a link to the main controller 200 compatible bus bar/net. Typically, the master controller connects to the terminal or waits for a selectable item to make the selectable items 10

1322623 was able to be set. Most of the car's remote control systems are capable of communicating, and their connection terminals are standardized, but the use of terminals is determined by the manufacturer and/or model. In order to connect the main control connection units 110 and 170, in order to connect the main control connection units 110 and 170, the connection unit of the different types can be used to realize the connection of the remote control 400 signals via an antenna module and if necessary Transmitting a Response Signal to the Antenna In another embodiment of the present invention, the antenna connection portion 170 can be implemented by the main controller connection portion 1 1 . The option setting section 120 reads the menu setting of the main controller 200 and displays it on the display 150, allowing the mechanic to check/not check if it is needed. The project setting is completed, the selectable item data of the octet is processed 200, and it is checked whether the transfer and setting are normal. When the 1202 is connected to the main control via the main controller connection unit 1 1 0, the option setting unit 120 requests the main controller data, and returns the requested main controller data, and prepares an option to set the main controller. The controller data contains the model name of the main controller and his data, such as the name of the manufacturer, date of manufacture. The memory 140 is pre-existing in the single system, and may be updated based on the model. Therefore, via the diagnostic device of the present invention, the remote control system of the vehicle model and the manufacturer performs optional items. For example, Fig. 4 is an exemplary option setting menu. This option corresponds to the main controller data and the connection received by the main controller. This is a connection to the antenna. The antenna is coupled to a control module 300. By using the user with the previous option (for example, when the selectable transfer to the master option setting unit 200 is based on the received order form. The other option can be selected to select the manufacturer and can be used for different purposes. Setting. Example setting section 1 2 0 This is currently optional 11

1322623 Select item setting to output the selectable item menu in the option setting menu and the setting of each selection item, the user can check or not check. This input is used to be one of the sides mounted on the diagnostic device. Of course, other different input diagnostic devices can also be applied, wherein the touch item to which an input UI is applied is set by the user, and the option setting unit has the selected item setting data input by the selected item setting number in the memory 140. And sending the changed selection item to the main control. If some of the selection items of the main controller 200 are not selectable at the same time, the main error signal, and the option setting unit 120 receives the re-received set up. However, it is preferable to pre-store the steps of the spear memory 1404, and to cause the option setting unit to perform a step of checking two or more contradictory options, transmitting and re-entering the selected item. The main control diagnosing unit 1 30 is connected to the main control to check that the diagnosing unit 130 between the main controller 200 and the vehicle device outputs the list of the vehicle devices requesting the main diagnosis to the main controller 200, and displays the display to the display. A list between the main controller and the car unit. Subsequently, the diagnosis of the cars is performed and displayed. The car device can be classified into two-way communication f on the display 150. Output display 1 50, interface (UI) 1 60 can be 1$ button or a touch-type flash UI. Figure 4 illustrates a one-shot screen. When the selection 1 2 0 changes the pre-stored data, it becomes the user of the main controller 1 1 0 transmitter 200. Contradictory, that is, the controller 200 generates a signal and allows the data selected using the shield to eliminate the error message connector 1 1 and check the line state at the beginning of the setting selection. The master controls the controller data and will pre-1 0 0. Figure 5 is a diagnostic device that is normal or abnormal when wiring. Type I (with the main controller 12)

1322623 2 00), and one-way communication type. The one-way communication of the vehicle device is such that a signal controller 200 such as a remote call and vibrator is transmitted, but the main controller 200 cannot transmit a status or control command. An automotive device, such as an alarm operated by the main controller or an LED module, is also of the letter type. The two-way communication type of the automotive device is capable of transmitting a response signal to the inspection/control signal of the controller 200. An inspection signal transmits a control signal to an automotive device for checking the current state of the signal. The master controller 00 and the vehicle devices can be configured with the main controller diagnosing unit 130 for one type using two types, and the main controller diagnosing unit 1 30 transmits a test master. The controller 200 operates in a diagnostic mode, transmits an inspection device, and can signal the signal to be immediately or in response to the main controller diagnostic unit 130. The second type controller 200 does not support a diagnostic mode that diagnoses grounding or randomly transmits a control identical to the remote control 400 to check the operational status of each of the automotive devices. In both versions, the steam assisted one-way communication, such as the RPS or shock sensor' can operate only if the RPS device is activated or a shock is applied to the vehicle. The main controller diagnostic unit 130 can check the steam operation, and the automobile devices can be operated via a pipe expander, and the car device can be directly connected to the main controller 200. If the channel (AUX1~AUX8) is on the expander, for example, the main control signal type is only controlled to the main check signal 200 by the one-way communication status pre-state or the connection line by diagnosis. The first signal is transmitted to each connection, and the main portion 130 is tightly signaled, and the vehicle device is only used by the user to check the operation of the device, and the eight pipe diagnosis unit 13 1322623 130 controls the main controller 200. The pipe expander is used to output a control signal (blocking or pulse signal) for timing of each device.

The main controller 200 can store the type and time of the result generated by the vehicle to support a result record table function to transmit the data to the remote control of the owner, or to allow the data to be configured via an LCD. The antenna module checks the data. In this case, the main controller diagnostic unit 130 may perform a test signal execution result (type 1)' control signal execution result (type 2), and a sensor signal for diagnosis from the main controller 200 (two types) ) Read the result record table. Therefore, although the main controller 200 does not generate a response signal corresponding to a control signal, analyzing the result record table can confirm whether the related car device is properly wired. The display 150 displays the set state and diagnostic status of the selectable item. Preferably, a flat panel display such as an LCD' is used to make the present invention specific. Because the conventional LED cannot display the optional item settings of the remote control system of different cars and the diagnostic status of multiple car devices. The antenna/remote control diagnostic unit 180 is connected to the antenna module 300 via the antenna connection unit 170, and checks the operation of the antenna module 300 and the remote control 400. The antenna/remote control diagnostic unit 180 receives the main controller data and option setting data via the main controller connection unit 110, and reads the corresponding remote control button from the memory 1404. A function menu for outputting on the display 150. The function of a remote control button is determined by the basic function installed in the remote control system of the vehicle and an existing pipe expander. Therefore, there are various types of pipe expanders and various types of vehicle models that are available for remote control.

The function menu of 1322623 is stored in advance in the memory 140. When the operation of the inspection group 300 and the remote control 400 is one of the diagnostic devices, it is as shown in Fig. 6. The antenna/remote control diagnostic unit 108 analyzes the control signal from the antenna and displays it on the display 150, the control signal is a button command on the remote control 400 for checking the antenna and the remote end. Controls whether 400 is operating normally. In addition, the antenna/distant portion 1 800 can be coupled to the main control diagnostic unit 130 for use with the main controller 200 and the antenna module 300, and between the 300 and the The remote control controls communication and operation between 400. That is, the one-end control diagnosing unit 180 can transmit from the remote control 400 to the main control diagnosing unit 130 for causing the main control diagnosing unit to function as a car device or a corresponding button. Further, it passes through the main control diagnostic unit 130 for directly transmitting a control main controller 200. An automobile device embodying one of the present invention will be described in detail with reference to Fig. 3. Figure 3 is a flow chart of the diagnostic steps for a controller based on a preferred embodiment of the present invention.

First, the option setting step will be described. In step S100, after the setting is set to 100 and the main controller 200 is connected, when the option is set by the user, the diagnostic device 1 requests a signal to the main controller 200. In another embodiment, when the diagnostic device 1 is activated after the controller 200 to automatically check the connection state instead of being operated by the user, the main controller 200 transmits the display to the antenna module. The group 300 is diagnosed by the antenna module at the end of the module 300. The antenna module linger antenna/far control signal 1 3 0 diagnoses the bypass signal to the master of the operation step. The diagnostic setup menu is transmitted. Connect to the main mode to check! 15

1322623 Upon receiving the request signal from the diagnostic device 100 in step S105, the main controller 200 determines whether the proximity request signal is a predetermined valid signal. If the signal is valid, the main control data is sent in response. The master controller data is a model name and may include the manufacturer's name and/or manufacturing schedule. In step S1 1 0, when the main control data is received, the diagnosis 1 0 0 determines whether the optional item of the received model name can be set, and if the selectable items can be set, the memory is selected from the memory 1 4 0 A corresponding selectable item menu is displayed on the display 150. The diagnostic device 1 0 〇 notifies the main controller 200 that the setting of the selectable item of the associated name has been prepared. In step S115, the master 200 transmits an inspection signal (Ack) to the diagnostic device 100 for notification. In some embodiments, the steps S 11 0 and S 11 may be skipped. In step S120, the diagnostic device 100 transmits a read selectable to the main controller 200. In step S125, the main controller 200 sends the stored currently selectable item setting data of the digital block to the device 100 as a readable readable signal. In step S130, the diagnostic device 100 outputs the current option setting data received from the master 200, allowing the user to change the current item status. Further, the check-check data input via the input UI 160 is temporarily stored in the memory 140. When the user completes the selectable items, the item settable data temporarily stored in the memory 140 is transmitted to the controller 200 as a write selectable item signal. Nearly one must be transmitted and the other device selected to read, the model system should be 5 ° signal post-transmission diagnostics selection unchecked settings select the main 16

1322623 In step S135, the main controller 200 updates the currently selectable item to become the received selectable item data. In addition, the clinic 100 then reads the current selectable item set of the main controller 200 and the selectable item data temporarily stored in the memory 140 to check whether the selectable item setting data is correctly updated. At the step of the main controller 200 and the plurality of car devices, the diagnostic device 100 transmits a test car device #1 command to the master 200 in step S200. If the main controller is capable of operating in a diagnostic mode, the test command is a test signal that the main controller cannot support a diagnostic mode, and a control signal is in step S205, in the case of a test signal, The main control transmits a signal to the car device #1 and checks a response signal of the received corresponding signal, and transmits the result to the diagnostic device 1 〇〇 control signal, the main controller 200 transmits the complete phase number, or Is a corresponding operation command to the car device #1, and receives a response signal from the command, and transmits the response signal to the medical device 100. Of course, the operation of the car device #1 can be visually inspected. When the controller 200 transmits a message of whether or not a response is received to the clinic 100, the normal or abnormal operation of the car device #1 is automatically performed. If the operation must be visually checked, the user can directly input the abnormal operation. In step S210, the car device #1 transmits an answer to the check signal response signal (Ac k) or answers a response signal from the command to the device 200. In step S215, the main controller 200 determines the other steam item setting means, and compares, the matching controller 20 of the turn can be, or the checker 200 of the checker is in the same letter to the corresponding breaking device if the main Broken device display. Normal or number one main control car unit 17

1322623 This reset 100 is transmitted after the diagnosis is completed or after the diagnosis is completed. In addition, if the diagnostic device is received, the main controller can record the result in the result record table. In step S220, based on whether the car device #1 or the associated car device correctly displays the result on the display 150 with the master. Describe the diagnosis of the wiring sensor signals of the plurality of automobile devices. In step S330, when the user #2, the diagnostic device 100 transmits a test command 1 when a sensor signal is input, a response signal state is transmitted, and the response signal can be received. The main controller 200 is next to step S305. If the user activates the additional vibration, the automobile device #2 generates a signal and inputs it to step S310. When the main controller 200 transmits a sensor signal to the diagnostic device 1, The type of the sensor signal is used to determine the connection of the main controller of the automobile to the vehicle, and the result is displayed, indicating the step of diagnosing the antenna/remote control, and the d-line module 300 receives the remote from the remote Control 400 is input to the diagnostic device 100. The remote control number includes an authentication data for identifying and confirming the data input by the twisted ammonium. In step S405, the diagnostic device 100 transmits the response signal to one of the diagnostic devices 100, so that only the response is transmitted. The response signal of the letter determines the connection of the controller 200, and the step of generating only the command to diagnose the car device. The main controller 200, the number, or the signal converted to one. The remote calling device or the primary controller 200 is applied. The corresponding input signal is sent to the diagnostic device 100 to check if the device #2 is correct and & Step S400, one of the control signals of the day, and the remote control associated with the control signal of the system is: the control signal is used to read the identification data of the remote control 400 by 18 1322623, and in the step S410.
