In recent years, with the continuous innovation of vehicle technology, vehicles have more and more functions and services (such as lane shift sensing, tire pressure sensing or front and rear distance sensing). In order to achieve the aforementioned functions and services, more and more electronic devices and sensors are installed in the vehicle, and the number and complexity of the lines are also increased, resulting in disadvantages such as increased line cost and complicated vehicle control system lines. .

[0003]

Please refer to FIG. 1. FIG. 1 is a circuit diagram of a conventional first vehicle control system. As shown in FIG. 1, a conventional vehicle control system 10 includes a plurality of switching elements, a plurality of body members, and a power source 104. In this example, the plurality of switching elements are exemplified by a headlight switch 100a, a directional light switch 100b, a warning light switch 100c, a horn switch 100d, and a start switch 100e; the plurality of body components are a high beam 102a, a low beam 102b, and a tail light. 102c, the left direction light 102d, the right direction light 102e, the horn 102f, the ignition device 102g, and the switch 102h are exemplified.

【0007】

If the user wants to turn on the warning light function, the warning light switch 100c can be operated to make the power source 104, the warning light switch 100c and the switch 102h form a path. Thereby, the switch 102h can obtain the power required for operation from the power source 104, and control the left direction light 102d and the right by discontinuously transmitting power to the left direction light 102d and the right direction light 102e. The direction light 102e is simultaneously turned on/off to achieve the warning light function.

[0008]

However, in the conventional vehicle control system 10, for each additional control function, a set of circuits and their associated lines must be added. When the control function reaches a certain number, the number of circuits of the vehicle control system 10 and the number of lines used will be considerable, which makes the setting cost of the line of the vehicle control system 10 too high and the system architecture is too complicated, which is unfavorable. Expansion or repair.

【0009】

In addition, since the power required for the operation of the plurality of body components (having a large current intensity) is transmitted to the plurality of body components via the plurality of switching elements, the plurality of switching elements must be provided with related components to avoid excessive current intensity. burn. This will result in an increase in the volume of the plurality of components.

For a more detailed understanding of the features and technical aspects of the present invention, reference should be made to the description and the accompanying drawings.

[0034]

A preferred embodiment of the present invention, in conjunction with the drawings, is described in detail below.

[0035]

Referring first to FIG. 2, FIG. 2 is a structural diagram of a vehicle control system according to a first embodiment of the present invention. As shown in FIG. 2, the present vehicle control system 2 mainly uses an integrated architecture and includes a body control module (BCM) 20, a plurality of switching elements 22, and a plurality of body members 24. The vehicle body control module 20 is electrically connected to the plurality of switching elements 22 via a plurality of output lines 260 and a plurality of input lines 262, respectively. Moreover, the body control module 20 is electrically connected to the plurality of body members 24 through other lines.

[0036]

Each of the switching elements 22 corresponds to at least one of a control function and the plurality of body members 24. When one of the plurality of switching elements 22 is subjected to a user operation, the operated switching element 22 can send a trigger signal to the body control module 20 via the input line 262 connecting the switching element 22 to enable the corresponding At least one of the body members 24 operates.

[0037]

Specifically, each of the switching elements 22 is electrically connected to at least one output line 260 and one input line 262, and an output signal can be received from the body control module 20 via the output line 260. If the switching component 22 receives the output signal and the user operation, the trigger signal is sent to the vehicle body control module 20 via the input line 262. If the switching element 22 receives only the output signal, it does not operate. Preferably, each of the switching elements 22 can be a headlight switch, a horn key, a start switch, a directional light switch or a brake light trigger, respectively, but is not limited thereto.

[0038]

It is worth mentioning that all or a part of the plurality of switching elements 22 can be connected to the body control module 20 via the same output line 260 or to the body control module 20 via the same input line 262. Moreover, a plurality of the switching elements 22 connected to the same output line 260 cannot simultaneously connect the same input line 262; and the plurality of switching elements 22 connected to the same input line 262 cannot simultaneously connect the same output line 260. . In other words, any two of the switching elements 22 cannot simultaneously connect the same output line 260 and the same input line 262. Thereby, the present invention can effectively reduce the number of lines by causing the plurality of switching elements to share the same line.

[0039]

The plurality of body members 24 are used to implement different such control functions. Preferably, the plurality of body components 24 are respectively a headlight, a horn, an ignition device, a left directional light, a right directional light or a brake light, but are not limited thereto.

[0040]

The body control module 20 can sequentially send the complex output signal to the complex switching element 22 via the complex output line 260 based on the timing, and receive the complex input signal via the complex input line 262. Specifically, the vehicle body control module 20 transmits the plurality of output signals via the plurality of output lines 260 according to a predetermined sequence or a predetermined time interval. Preferably, the output signal has a specific voltage (such as 5 volts (V)) of electrical signals, but is not limited thereto.

[0041]

For example, the body control module 20 can sequentially send the plurality of output signals from the first output line 260 to the last output line 260, and each time the output signal is sent is separated by a first critical time (eg, 5 milliseconds (ms)). Alternatively, the body control module 20 can transmit the output signal from the first output line 260 every 5 milliseconds, and send the output signal from the second output line 260 every 7 milliseconds, every 9 milliseconds from the third line. The output line 260 sends the output signal once... and so on.

[0042]

The body control module 20 and the plurality of output lines 260, the plurality of switching elements 22, and the plurality of input lines 262 respectively form a plurality of loops, such that the plurality of output signals from the body control module 20 can pass through the plurality of input lines 262 returns to the body control module 20 (ie, the plurality of output signals become the plurality of input signals).

[0043]

In more detail, in a normal state (that is, the plurality of switching elements 22 do not accept the user operation), the number of the plurality of output signals sent by the body control module 20 is equal to the number of the plurality of input signals received. . The plurality of input signals received by the vehicle body control module 20 include the plurality of output signals and at least one of the trigger signals in a triggering state (ie, at least one of the plurality of switching elements 22 accepts the user operation) The number of output signals will be less than the number of the complex input signals.

[0044]

Next, how the body control module 20 determines whether each of the input signals is the trigger signal. The body control module 20 can determine whether the received one of the plurality of input signals is the trigger signal according to the timing, and further determine the switching component 22 corresponding to the trigger signal when determining that the input signal is the trigger signal. .

[0045]

Specifically, since the complex output signal is sent based on the timing, if the input signal is the output signal, a receiving time or a receiving sequence of the input signal must meet the foregoing timing. If the input signal does not meet the foregoing timing, it may be determined that the input signal is the trigger signal. And the receiving time or the receiving of the trigger signal sent by the body control module 20 by the different switching element 22 is different, because the output line 260 or the input line 262 connected to the switching element 22 is different. The order will also be different.

[0046]

After the body control module 20 recognizes the switching element 22 corresponding to the trigger signal, the body component 24 corresponding to the switching element 22 is controlled to operate. Specifically, the vehicle body control module 20 is further connected to a power source 28 to obtain power required for the operation of the vehicle control system 2. The body control module 20 provides an operating current to the corresponding body member 24 via supply/interruption to control the operation/stop operation of the corresponding body member 24.

[0047]

It should be noted that in the present invention, a single switching element 22 may correspond to only one of the body components 24, or may correspond to a plurality of the body components 24, and is not limited.

[0048]

Continuing to refer to FIG. 3, FIG. 3 is a structural diagram of a vehicle body control module according to a first embodiment of the present invention. As shown in FIG. 3, the body control module 20 mainly includes a signal detecting circuit 200, a power input circuit 202, a body component control circuit 204, and a controller 206. The controller 206 is electrically connected to the signal detecting circuit 200, the power input circuit 202, and the body component control circuit 204.

[0049]

The signal detecting circuit 200 is electrically connected to the complex output line 260 and the complex input line 262. Specifically, the complex output line 260 and the complex input line 262 are integrated into a single signal connector (such as the signal connector 26 shown in FIG. 4). The signal detecting circuit 200 includes a signal port 埠 2000 for detachably connecting the signal connector 26.

[0050]

The power input circuit 202 is electrically connected to the power source 28 for taking power from the power source 28 and transmitting the power to the components of the vehicle body control module 20 as power required for operation.

[0051]

The body component control circuit 204 is electrically coupled to the plurality of body components 24 and provides the power required to operate the plurality of body components 24. Specifically, the body component control circuit 204 transmits a plurality of the operating currents to the plurality of body members 24 via the plurality of power lines to provide the power required to operate each of the body members 24, respectively.

[0052]

It is worth mentioning that since the current intensity of the power required for the operation of each of the body components 24 may be different, the body component control circuit 204 can transmit the operating current of different current intensities in different power lines.

[0053]

The controller 206 sends the complex output signal and receives the complex input signal via the signal detecting circuit 200. The controller 206 automatically determines whether one of the received plurality of input signals is the trigger signal, and when one of the plurality of input signals is the trigger signal, identifies the switching element 22 corresponding to the trigger signal, and The body component control circuit 204 provides or interrupts the power required to operate the body component 24 corresponding to the switching component 22.

[0054]

Specifically, the body control module 20 further includes a current conversion circuit 208 electrically connected to the controller 206 and the body component control circuit 204. When the controller 206 recognizes the triggered switching element 22 by the trigger signal, the controller 206 transmits a control current to the current converting circuit 208. The current conversion circuit 208 converts the control current to the operating current, wherein the current intensity of the operating current corresponds to the current intensity of the power required to operate the body component 24 corresponding to the triggered switching element 22. Then, the current conversion circuit 208 outputs the operating current to the body component control circuit 204 to transmit the operating current to the body component 24 corresponding to the triggered switching component 22 via the power line, and provide or interrupt the supply of the body component The body component 24 corresponding to the triggered switching element 22 operates with the required power. Preferably, the current conversion circuit 208 is a Relay or a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET), but is not limited thereto.

[0055]

In another embodiment of the present invention, the body component control circuit 204 includes a large current component port 2040 and a small current component port 2042.

[0056]

The high current component port 2040 is electrically coupled to all or a portion of the plurality of body members 24 via all or a portion of the plurality of power lines to provide a greater current to the full or portion of the plurality of body members 24. The small current component port 2042 is electrically connected to the remaining plurality of body members 24 via the remaining plurality of power lines to provide a smaller current to the remaining plurality of body members 24.

[0057]

Specifically, the current conversion circuit 208 can convert the control current into the operating current with a large current intensity, and output the operating current to the specific body component of the plurality of body components 24 via the large current component port 2040; Alternatively, the control current is converted into the operating current having a small current intensity, and the operating current is output to the specific body member of the plurality of body members 24 via the small current element connection port 2042.

[0058]

In another embodiment of the present creation, the controller 206 includes a timer 2060. The controller 206 can time the first critical time via the timer 2060, and send the output signal via the different output line 260 after each time the first critical time elapses. Moreover, the controller 206 can count a second critical time via the timer 2060, and send the output signal via the different output line 260 after each second critical time elapses. Preferably, the second critical time is greater than or equal to the number of the plurality of switching elements 22 multiplied by the first critical time.

[0059]

For example, if the first critical time is 2 milliseconds and the number of the complex output lines 260 is three, the second critical time needs to be no less than 6 milliseconds. The controller 206 first transmits the output signal via the first output line 260; and after the first critical time (2 milliseconds) elapses, transmits the output signal via the second output line 260; After a critical time (2 milliseconds), the output signal is sent via the third output line 260. Then, the controller 206 can send the output signal via the first output line 260 a second time after the first critical time (2 milliseconds) elapses. At this time, the two output signals of the first output line 260 are sent at least 6 milliseconds apart (ie, 2 milliseconds, 3 output lines 260).

[0060]

Since the switching component 22 needs to receive the output signal at the same time and accept the user operation, the trigger signal can be sent. The present invention controls the transmission frequency of the output signal by adjusting the first critical time and the second critical time, and the sensitivity of the switching element can be effectively adjusted.

[0061]

In another embodiment of the present creation, the body control module 20 can enter a sleep state. When the vehicle body control module 20 is in the sleep state, the second critical time is extended to a third critical time. Preferably, the third critical time is greater than the second critical time.

[0062]

For example, when the body control module 20 is in the sleep state, the second critical time (eg, 6 milliseconds) may be extended to the third critical time (eg, 20 milliseconds). The present invention can effectively reduce the power consumption of the vehicle body control module 20 by extending the predetermined time interval of transmitting the output signal via the same output line 260.

[0063]

In another embodiment of the present invention, the components of the body control module 20 further conform to a particular set of rules. In the specific setting rule, the signal detecting circuit 200 and the body component control circuit 204 are respectively disposed on two sides of the vehicle body control module 20. Thereby, it is possible to effectively avoid the line connecting the plurality of switching elements 22 and the line connecting the plurality of body members 24.

[0064]

The current conversion circuit 208 is disposed between the controller 206 and the body component control circuit 204. Thereby, the length of the line connected from the controller 206 to the body component control circuit 204 via the current conversion circuit 208 can be effectively minimized, and the volume of the vehicle body control module 20 can be effectively reduced.

[0065]

The power input circuit 202 and the body component control circuit 204 are disposed on different sides. Further, the power input circuit 202 and the signal detecting circuit 200 are disposed on the same side. In general, the cross-sectional area of the power line is much larger than the cross-sectional area of the signal line. Therefore, the area of the signal detecting circuit 200 (connecting the signal line (such as the complex output line 260 and the complex input line 262)) is compared with the area where the body component control circuit 204 (connecting the plurality of power lines) is located. Usually have more unused settable space. By setting the power input circuit 202 and the signal detecting circuit 200 on the same side, the present invention can effectively utilize the configurable space inside the vehicle body control module 20 to minimize the volume of the vehicle body control module 20.

[0066]

Please refer to FIG. 4 , which is a schematic diagram of the appearance of the vehicle body control module according to the first embodiment of the present invention. As shown in FIG. 4, in the embodiment, the complex output line 260 and the complex input line 262 are integrated into a single signal connector 26, and the signal port 埠2000 is detachably connected. The high current component connection port 2040 and the small current component port 2042 are integrated into a single component port 2046.

[0067]

It is worth mentioning that the vehicle body control module 20 of the embodiment is mainly applied to a motor vehicle such as a locomotive or an electric bicycle. In order to be effectively applicable to a motor vehicle, the body control module 20 of the present invention has a waterproof structure and a protection structure to prevent the loss of components of the vehicle body control module 20 caused by rain or impact.

[0068]

Next, the waterproof structure and the protective structure will be described. The body control module 20 further includes an upper cover 40 and a lower cover 42. The upper cover 40 and the lower cover 42 respectively include an upper cover assembly structure and a lower cover assembly structure corresponding to each other. Preferably, the upper cover assembly structure and the lower cover assembly structure are cassettes, but are not limited thereto. In another embodiment of the present invention, the assembly structure may also be a plurality of holes for receiving screws.

[0069]

After the upper cover 40 and the lower cover 42 are assembled, at least the signal detecting circuit 200, the power input circuit 202, the body component control circuit 204, the controller 206, and the current converting circuit 208 can be covered. Preferably, the upper cover 40 and the lower cover 42 are made of a waterproof material such as metal or plastic.

[0070]

Further, a recessed structure is disposed on each side of the upper cover 40 or the lower cover 42. The body control module 20 further includes a first waterproof plug 44 and a second waterproof plug 46. The first waterproof plug 44 and the second waterproof plug 46 include at least one hole through which the plurality of output lines 260 and the plurality of output lines 262 can be connected to the plurality of switching elements 22, the plurality of power lines can pass through The hole is connected to the plurality of body members 24, and a line connecting the power output circuit 202 can be connected to the power source 28 through the hole.

[0071]

Moreover, after the upper cover 40 and the lower cover 42 are assembled, the recessed structures on both sides can be completely adhered to the first waterproof plug 44 and the second waterproof plug 46, respectively. Thereby, the body control module 20 of the present invention can have a waterproof effect and a protective effect, and can be applied to a motor vehicle.

[0072]

Continuing to refer to FIG. 5 and FIG. 6A-6C , FIG. 5 is a schematic diagram of the use of the vehicle body control module according to the first embodiment of the present invention, and FIG. 6A is a waveform diagram of the output signal and the input signal of the body control module of FIG. 5 in a normal state. FIG. 6B is a waveform diagram of the output signal of the body control module of FIG. 5 in a sleep state, and FIG. 6C is a waveform diagram of the input signal of the body control module of FIG. 5 in a trigger state, illustrating the body of the present invention. The connection mode of the control module 20 and the line between the complex switching elements 22.

[0073]

In the present embodiment, the complex switching element 22 takes six sets of the complex switching elements 22a-22f as an example. The vehicle body control module 20 includes a plurality of signal outputs 埠O1-O3 and a plurality of signal outputs 埠I1-I3. The plurality of signal outputs 埠O1-O3 are respectively connected to the three output lines 260a-260c for transmitting the output signals; the complex signal inputs 埠I1-I3 are respectively connected to the three input lines 262a-262c for receiving the output signals.

Each of the switching elements 22a-22f is coupled to one of the plurality of output lines 260a-260c and one of the plurality of input lines 262-262c. In more detail, the switching element 22a is connected to the output line 260b and the input line 262a; the switching element 22b is connected to the output line 260c and the input line 262a; the switching element 22c is connected to the output line 260a and the input line 262b; The switching element 22d is connected to the output line 260c and the input line 262b; the switching element 22e is connected to the output line 260a and the input line 262c; the switching element 22f is connected to the output line 260b and the input line 262c.

[0075]

In this embodiment, the first critical time is 2 milliseconds (ms), and the second critical time is 10 milliseconds (ms). In other words, the body control module 20 transmits the output signal via the output line 260a at the 0th millisecond; at the 2nd millisecond, the output signal is transmitted via the output line 260b; The output line 260c transmits the output signal; at the 10th millisecond, the output signal is retransmitted via the output line 260a; at the 12th millisecond, the output signal is again transmitted via the output line 260b... and so on.

[0076]

Since the speed of the signal transmission is extremely fast, the body control module 20 emits the output signal at a time that is almost without any delay in receiving the input signal. Therefore, in the normal state (that is, when the plurality of switching elements 22a-22f do not accept the user operation), the waveform diagram of the complex output signal sent by the complex signal output 埠O1-O3 and the complex signal input 埠I1 The waveform of the complex input signal received by -I3 is almost the same (as shown in Fig. 6A).

[0077]

When the body control module 20 is in the sleep state, the body control module 20 may extend the second critical time (10 milliseconds) to the third critical time (for example, 20 milliseconds), or the first The critical time (2 milliseconds) is extended to a fourth critical time (in the case of 5 milliseconds). As can be seen from the waveform diagrams of FIG. 6A and FIG. 6B, when the vehicle body control module 20 is in the sleep state, the predetermined time interval of the transmission time of the output signal will be extended (ie, the transmission frequency of the output signal is Lower, the body control module 20 can be reduced in power consumption.

[0078]

Referring to FIG. 6C, in the trigger state (here, the switching component 22b and the switching component 22c accept the user operation as an example), the body control module 20 can obtain a waveform diagram of the input signal as shown in FIG. 6C. . Compared to the waveform diagram of FIG. 6A, the waveform diagram of FIG. 6C adds an input signal S1 and an input signal S2. Therefore, the body control module 20 can determine that the input signal S1 and the input signal S2 are the trigger signals after receiving.

[0079]

The body control module 20 then identifies the switching elements corresponding to the input signal S1 and the input signal S2. The input signal S1 is received via the signal input 埠I1, and the receiving time of the input signal S1 is the same as the sending time of the output signal sent via the signal output 埠O3 (ie, the input signal S1) The receiving time is the same as the receiving time of the input signal received via the signal input 埠I3). Therefore, the body control module 20 can determine that the switching element corresponding to the input signal S1 must be the switching element 22b that connects the output line 260c and the input line 262a.

[0080]

The input signal S2 is received via the signal input port 埠I2, and the receiving time of the input signal S2 is the same as the sending time of the output signal sent via the signal output 埠O1 (ie, the input signal S2) The receiving time is the same as the receiving time of the input signal received via the signal input 埠I1). Therefore, the body control module 20 can determine that the switching element corresponding to the input signal S2 must be the switching element 22c that connects the output line 260a and the input line 262b.

[0081]

By comparing the waveform diagram in the normal state with the current waveform diagram, the creation can effectively identify the switching element corresponding to the trigger signal.

[0082]

Continuing to refer to FIG. 7, a flowchart of a vehicle control method according to a first embodiment of the present invention is shown. The vehicle control method of this embodiment is mainly implemented by the vehicle control system 2 shown in FIG. 2.

[0083]

Step S70: sequentially transmitting the complex output signal based on the timing. Specifically, the vehicle body control module 20 sequentially transmits the plurality of output signals to the plurality of switching elements 24 according to the predetermined sequence or the predetermined time interval.

[0084]

Step S72: accept the user operation and send the trigger signal. Specifically, one of the plurality of switching elements 22 transmits the trigger signal to the vehicle body control module 20 via one of the plurality of input lines 262 when receiving the user operation.

[0085]

Step S74: determining whether the input signal is the trigger signal. Specifically, the body control module 20 determines, according to the timing at which the plurality of output signals are transmitted, whether the received input signal is the trigger signal generated in the step S72.

[0086]

Preferably, the body control module 20 determines that the input signal that is in the wrong order is the trigger signal when the plurality of input signals are simultaneously received through the different input lines 262. Alternatively, the body control module 20 calculates an interval between the receiving time of the input signal and the receiving time of the input signal received via the same input line 262, and the interval does not exceed the second critical time. When the input signal is determined to be the trigger signal.

[0087]

If the input signal is the trigger signal, the step S76 is performed; otherwise, the step S70 is repeatedly executed to continuously send the output signal to detect the user operation.

[0088]

Step S76: Control the corresponding body component 24 to operate. Specifically, when determining that one of the plurality of input signals is the trigger signal, the body control module 20 identifies the triggered switching component 22 corresponding to the trigger signal, and controls the triggered switching component 22 The corresponding body element 24 operates.

[0089]

Continuing to refer to FIG. 8, a flow chart of a vehicle control method according to a second embodiment of the present invention is shown. The vehicle control method of this embodiment is mainly implemented by the vehicle control system 2 shown in FIG. 2.

[0090]

Step S800: transmitting the output signal via the different output line 260 every other first critical time. Specifically, the body control module 20 sequentially transmits the output signal through different output lines 260 each time the first critical time elapses, so that the output signals of the different output lines 260 are sent. The time interval is the first critical time.

[0091]

Step S802: The output signal is sent via the same output line 260 every second critical time. The second critical time is greater than the number of the complex switching elements 22 multiplied by the first critical time. Specifically, the vehicle body control module 20 transmits the output signal through the same output line 260 again every time the second threshold time is calculated, so that the same output time of the output signal of the output line 260 is sent. The interval is the second critical time.

[0092]

Step S804: accept the user operation and send the trigger signal.

[0093]

Step S806: determining whether the input signal is the trigger signal. If the received input signal is the trigger signal, step S808 is performed; otherwise, step S800 is repeatedly executed to continuously send the output signal to detect the user operation.

[0094]

It is worth mentioning that the steps S800-S806 are performed simultaneously without any order. In other words, while the body control module 20 continues to transmit the output signal, it also determines whether the input signal is received by the trigger signal, and the switching elements 22 can simultaneously accept the user operation.

[0095]

Step S808: generating the control current. Specifically, after the body control module 20 recognizes the triggered switching component 22 corresponding to the trigger signal, the control current is generated to control the body component 24 corresponding to the triggered switching component 22 .

[0096]

Step S810: Converting the control current to the operating current. Specifically, the vehicle body control module 20 converts the control current into the operating current having different current intensities. Preferably, the current intensity value of the operating current is the value of the current intensity of the operating current of the switching element 22 corresponding to the body component 24.

[0097]

Step S812: transmitting the operating current to the body component 24. Specifically, the body control module 20 transmits the operating current to the body component 24 corresponding to the triggered switching element 22 to provide the power required to operate the body component 24.

[0098]

Therefore, the vehicle body control module 20 only needs to provide the control current with a small current intensity, and can also control the body component 24 with a large current intensity of the current required for operation, and the vehicle control system 2 can effectively save power consumption. The risk of the body control module 20 being burned due to excessive current intensity is reduced.

[0099]

Referring to FIG. 9, a detailed flowchart of step S802 of FIG. 8 described above is shown.

【0100】

Step S8020: Detect whether the sleep state is in progress. If the body control module 20 detects that it is currently in the sleep state, step S8022 is performed; otherwise, step S8024 is performed.

【0101】

Step S8022: The output signal is sent via the same output line 260 every third critical time. Preferably, the third critical time is greater than the second critical time. Specifically, when the vehicle body control module 20 is in the sleep state, the power consumption loss can be reduced by extending the predetermined time interval for issuing the complex output signal to the third critical time. Then step S804 is performed.

【0102】

Step S8024: The output signal is sent via the same output line every second critical time. Then step S804 is performed.

【0103】

This creation can effectively reduce the size of the body control module and reduce the number of lines connected to the body control module. Moreover, the present invention does not need to provide an encoder and a decoder to effectively identify the switching elements triggered by the user.
