Description

Idling start-stop device for operating with mode}

The present invention relates to an idle limit control device for controlling an operation according to a mode, and more specifically, to read a variety of modes for blocking idling through a vehicle state signal, and outputs the read mode so that the driver can check the vehicle state. In addition, the present invention relates to a device for controlling the operation of the idle limiting device according to the mode.

The dazzling industrialization has brought humanity with its convenience, but with its side effects. One of them is environmental pollution by carbon dioxide generated when burning underground resources such as petroleum. In addition, since underground resources are limited in reserves, there is a good reason to save even if it is not just to prevent environmental pollution.

In particular, automobiles, one of the products of industrialization, are the tools people are most likely to encounter in real life, resulting in a significant amount of fuel consumption and carbon gas emissions.

In general, the car can be driven while the engine is running. In addition, in order to drive in the optimal state it is desirable to go through the process of preheating the engine in the state of starting.

But just because the engine is running, it is not necessarily used for the sole purpose of driving a car. In other words, even after the initial preheating process, the vehicle does not start driving immediately, and further goes through excessive preheating process. In some cases, the vehicle must be stopped due to a signal or traffic jam.

In this case, the engine is running when the vehicle is stopped, not the driving situation is called 'idling'. In other words, excessive idling consumes fuel unnecessarily and thus increases carbon emissions, resulting in increased environmental pollution.

To this end, as disclosed in Korean Patent Laid-Open Publication No. 10-2011-0084808, a technology for solving fuel consumption and carbon emission increase problems caused by excessive idling has been proposed by allowing the engine to be temporarily stopped when the vehicle is idling.

However, the idling limiter must not overwhelm the vehicle in the process of stopping the engine and safety must be taken into account. That is, even if the driver is equipped with an idling limiter to save fuel and reduce carbon emissions, a variety of information and additional functions must be provided so that the operation can be performed with safety as a top priority without burdening the vehicle. However, the conventional idling limiting devices only provide the function of stopping and restarting the engine in the idling state, and the above descriptions are not applied.

The present invention has been made to solve the problems of the prior art as described above, and receives various vehicle status signals from the vehicle ECU and analyzes them to read the mode indicating the current status of the vehicle, and operate according to the read mode. It is an object of the present invention to provide an idling limiting device that controls the operation according to a mode that allows the driver to perform the operation while checking the state of the vehicle by providing the driver with the state of the vehicle including the mode in real time. .

In addition, even if the state of the vehicle analyzed through the vehicle status signal is normal, the idling can be prevented even through the inclination or position of the vehicle, or the idling can be forcibly cut off, thereby improving safety and efficiency. It is another object to provide an idling limiting device for controlling the operation according to.

An idle limiting device for controlling an operation according to a mode according to the present invention for achieving the above object comprises: a communication unit for receiving a vehicle status signal from a vehicle ECU and analyzing the received vehicle status signal to read a mode; And an idle cut control unit configured to mount a mode read by the communication unit, output the mounted mode through a display, and control an engine stop according to the mounted mode when an idle cut signal is input according to a driver's operation. It includes.

Here, the communication unit, the communication unit for receiving a vehicle status signal from the vehicle ECU; A reading unit for reading a mode by analyzing the vehicle status signal; And a mode transmission unit for transmitting the mode read by the reading unit to the idling cutoff control unit, wherein the idling cutoff control unit includes: a mode mounting unit for mounting a mode received from the communication unit; A display operating unit configured to output the mounted mode through a display; And an idling blocking operation unit controlling the engine stop according to a signal input by a driver's operation and a mode mounted in the mode mounting unit.

In addition, the vehicle status signal received by the communication unit of the communication unit includes a speed, engine speed, battery voltage, coolant temperature, foot brake state, side brake state, gear state, door state, switch state or error code, When the reading part of the communication unit analyzes the vehicle status signal, the engine speed is less than the preset value, the battery voltage is less than the preset value, the coolant temperature is more than the preset range, or the door is open. If it is confirmed that an error code has been received, read in 'error mode', and if the engine speed, battery voltage and door state are normal and the error code is not received but it is confirmed that the coolant temperature is below a preset range, Warm up mode, the engine speed, battery voltage, If no error code is received and the coolant temperature is within the preset range and the speed is confirmed to be 0, the engine is read in the idling mode, and the engine speed, battery voltage, and door state are normal. If it is not received and it is confirmed that the coolant temperature is within a preset range and the speed is higher than the preset value, it may be read in the 'driving mode'.

In addition, the idling cut-off operation unit of the idling cut-off control unit, the engine is stopped or restarted in accordance with the idling cut signal or the idling cut-off signal input by the driver's operation, the mode mounted on the mode mounting portion is the idling mode Only when the idling input signal is input can stop the engine simply.

The apparatus may further include an external control unit configured to analyze the tilt information, the position information, and the time information of the vehicle, to generate external control analysis result information, and to transmit the external control analysis result information to the communication unit. A tilt sensor for measuring tilt of the vehicle and outputting tilt information; A GPS receiver for receiving coordinate information and time information through a GPS satellite; And an external control analyzer configured to analyze tilt information, coordinate information, and time information output from the tilt sensor and the GPS receiver, and generate external control analysis result information to transmit to the communication unit.

Here, the external control analysis unit of the external control unit, when the inclination information of the vehicle is greater than a predetermined value as a result of analyzing the external control analysis result indicating 'external control mode-tilt' to the communication unit side and And analyzing the coordinate information and the time information, when the vehicle is determined to be prohibited from idling at a specific location in a specific time zone, the external control analysis result information indicating 'external control mode-no idling blocking' is read. If it is determined that the vehicle is to be forced to block idling at another specific position as a result of analyzing the coordinate information and transmitting the information to the communication unit, the external control analysis result information indicating 'external control mode-idling forced blocking' is returned. It can be transmitted to the communication unit side.

In addition, when the reading unit of the communication unit receives the external control analysis result information from the external control unit, it reads in an 'external control mode' (tilt, no idling blocking or idling forced blocking), and is equipped with a mode of the idling blocking control unit. The unit is equipped with the 'external control mode', and the idling blocking operation unit of the idling blocking control unit, when the 'external control mode (tilt)' or 'external control mode (idle blocking prohibition)' is mounted Even if it is input, the engine stops the simple stop, and when the 'external control mode (idle stop)' is mounted, the engine is stopped even if the idling stop signal is not input when the idle mode is satisfied. It can be easily stopped.

The present invention has the following effects.

First, the communication unit receives the vehicle status signal from the vehicle ECU, analyzes it, reads the mode, and mounts the read mode in the idle cutoff control unit. Do not overload the vehicle by preventing it from happening.

In addition, by displaying the mounted mode and the status of the vehicle on the display, the driver can check the current vehicle status in real time to check whether the operation for blocking the idling can be performed, and the idling even when the operation for the idling blocking is performed. If it is not blocked, you can see why it did not work.

For example, a driver who cares about his vehicle, because it is believed that the more the preheating is better, the more fuel wastage and carbon emissions due to the excessive preheating process, but as in the present invention, when the preheating (warming up) process is completed, The output can be displayed on the display to inform the driver of unnecessary idling. On the other hand, the vehicle may be overwhelmed by attempting the idling cutoff operation without knowing whether there is an error in the vehicle status. If the error mode is confirmed through the display, the idling cutoff operation may not be attempted in the first place. It can raise even more.

In addition, by storing and outputting the vehicle status, the number of idle shutdowns, fuel savings, and carbon emission savings, the driver can feel the benefits of using the device and inspire the user to use the device more and more. As a result, it is possible to create a virtuous cycle structure that further increases fuel savings and carbon emission reduction effects.

In addition to vehicle status, if the vehicle is inclined (ie hill) when the vehicle is in a stopped state, it is not possible to stop idling, further increasing safety, or when the vehicle is in a certain location at certain times (frequent slowing and stopping It is possible to increase the convenience by disabling idle idling even if repeated), or to save fuel and carbon emissions by forcibly cutting idle idling without the driver's operation in a specific location (eg garage). It can be even higher.

The mode is mounted by transmitting to the cutoff control unit 130. Vehicle status signals received from the vehicle ECU 210 include speed, engine speed (L-Volt), battery voltage (B-Volt), coolant temperature, brake (footbrake) status, side brake status, gear status, door status. And various switch states and error codes. The communication unit 110 which receives the vehicle status signals and reads the mode through the analysis and transmits the read mode to the idling cutoff control unit 130 is the communication unit 111, the reading unit 112, and the mode transmitting unit 113. ).

The communication unit 111 connects the vehicle ECU 210 with a predetermined communication channel and receives a vehicle state signal from the vehicle ECU 210.

The reading unit 112 analyzes the vehicle state signal received by the communication unit 111 to read the mode. The reading unit 112 reads the mode by comparing and analyzing the vehicle status signal with reference information stored in a separate storage device (not shown). In addition, the reading unit 112 reads the mode in consideration of not only the vehicle status signal but also external control analysis result information received from the external control unit.

 For a specific process of reading the mode in some cases through the vehicle status signal and the external control analysis result information in the reading unit 112 of the communication unit 110, a method of operating the idle limit device shown in FIGS. Explain through

The mode transmission unit 113 transmits the mode read by the reading unit 112 to the idle cut control unit 130. Here, the mode transmission unit 113 includes the vehicle state signal received by the communication unit 111 and the external control signal received by the external control unit 120 together with the mode read by the reading unit 112. Can be sent to.

The external control unit 120 analyzes the external control signal and transmits the external control analysis result information to the communication unit 110 so that the reading unit 112 of the communication unit 110 reads the mode. The external control unit 120 includes a tilt sensor 121, the GPS receiver 122 and the external control analysis unit 123.

The inclination sensor 121 measures the inclination of the vehicle 200.

The GPS receiver 122 receives coordinate information and time information through the GPS satellites.

The external control signal (tilt information, coordinate information, time information) obtained through the tilt sensor 121 and the GPS receiver 122 is sent to the external control analysis unit 123, the external control analysis unit 123 is external The control signal is analyzed, and external control analysis result information is generated and transmitted to the communication unit 110.

If the external control analysis unit 123 determines that the vehicle 200 is inclined to a predetermined value or more (for example, 10 degrees) through the tilt information received through the tilt sensor 121, the external control mode-tilting information is provided. External control analysis result information indicating the generated can be transmitted to the communication unit (110).

In addition, the external control analysis unit 123 determines that the vehicle 200 is located at a specific location in a predetermined time zone through coordinate information and time information acquired through the GPS receiver 122, 'external control mode-idle cutoff'. External control analysis result information indicating 'prohibited' can be generated and transmitted to the communication unit 110.

In addition, the external control analysis unit 123 is the information 'external control mode-idle blocking' when the vehicle 200 is located at another specific location through coordinate information and time information obtained through the GPS receiver 122. External control analysis result information indicating the can be generated and transmitted to the communication unit (110).

A detailed process of generating external control analysis result information according to a case in the external control analysis unit 123 will be described below with reference to FIGS. 6 to 9.

On the other hand, the external control analysis unit 123 may perform a comparative analysis in conjunction with a separate storage device (not shown) that stores the predetermined slope information, location information, time information.

The idle cut control unit 130 receives the mode read from the communication unit 110 and mounts the received mode to enable the mode-based idle cut operation, and also displays the mounted mode, the vehicle status signal, and an external control signal. By outputting through 140, the driver may check the current state of the vehicle 200. The idle blocking control unit 130 includes a mode mounting unit 131, a display operating unit 132, an idle blocking operation unit 133, and a memory 134.

The mode mounting unit 131 mounts the mode read and transmitted by the communication unit 110. Types of modes read and transmitted by the communication unit 110 may include a warm-up mode, an error mode, an external control mode, a driving mode, an idling mode, a simple stop mode, and the like. Each mode will be described in more detail with reference to FIGS. 2 to 9 below. The mode installed in the mode mounting unit 131 serves as a basis for determining whether to control the motion when the idling blocking operation is attempted by a predetermined driver operation.

The display operating unit 132 controls the display 140 to output the mounted mode, or outputs various vehicle status signals, external control signals, and the like. The display 140 is a screen output device that allows the driver to check the information with the naked eye. In addition, a separate speaker (not shown) or a lamp (not shown) may be further provided to output information by voice or light. In addition, a component for controlling the operation of the speaker (not shown) or the lamp (not shown) may be added to the idle block control unit 130.

The idle stop operation unit 133 stops or restarts the engine 220 of the vehicle 200 through an idle stop signal or an idle stop release signal operated by a driver. Of course, the idling cut-off operation unit 133 may or may not perform the idling cut-off operation for stopping the engine 220 according to the mode mounted by the mode mounting unit 131 even if there is a driver's manipulation.

In addition, the idling cutoff signal or idling cutoff signal received by the idling cut-off operation unit 133 refers to a signal such as a toggle operation of the foot brake, the on / off operation of the clutch, the on / off operation of the side brake, the neutral of the gear, etc. , These signals are those included in the vehicle status signal that is obtained from the sensors mounted on the respective operating devices and transmitted through the vehicle ECU 210 and the communication unit 110.

A detailed example of stopping or restarting the engine 220 by the idle blocking operation unit 133 by the idle blocking signal or the idle blocking release signal will be described later with reference to FIGS. 2 to 9.

The memory 134 stores mode information received from the communication unit 110, a vehicle status signal, an external control signal, and the like, and the information stored in the memory 134 is processed separately to display the display 140 for the driver to check later. Can be output via Information that can be stored or processed directly in the memory 134 and stored and output through the display 140 includes the currently loaded mode, total running time, idle time, idle stop time (simple stop time), warm up time, braking Count, speed, gear condition, start count, coolant temperature, clutch on / off information, rapid acceleration, braking, engine speed (RPM), high RPM, mileage, fuel usage, B-Bolt, L-Volt , Error code, etc.

In addition, the idle cut control unit 130 is a separate switch for receiving a user command so that the driver can select the information received in the signal or the memory 134 received from the communication unit 110 to check through the display 140 (not shown) H) may be further included.

The operation of each functional configuration of the idle limit device 100 according to the embodiment of the present invention described with reference to Figure 1 described above with reference to Figures 2 to 9 idle limit device according to an embodiment of the present invention. It will be further embodied through the method of operation of 100.

2 shows an example of a process of reading a mode in the communication unit 110 of the method of operating the idle limit device according to an embodiment of the present invention, mounting the same in the idle block control unit 130 and outputting it through the display 140. It is a flowchart for comprehensive description.

First, when power is supplied to the idle limit device 100, the reading unit 112 of the communication unit 110 determines whether the automatic transmission or the manual transmission is through the vehicle state signal. It is necessary to determine whether the automatic transmission and the manual transmission are read when the mode is read and whether or not the idle cut signal (or idle cut release signal) is input.

Thereafter, the communication unit 111 of the communication unit 110 receives a vehicle state signal from the vehicle ECU 210, and the reading unit 112 reads the mode through the received vehicle state signal. Here, the reading unit 112 reads the mode by referring not only to the vehicle status signal received from the vehicle ECU 210 but also to the external control analysis result information transmitted from the external control unit 120. Mode reading by the above will be described separately with reference to FIGS. 6 to 9.

As a result of the mode read by the reading unit 112, the warm-up mode (Fig. 3), the error mode (Fig. 3), the external control mode (Figs. 6 to 9), the driving mode (Fig. 4), and the idling mode (Fig. 3). 4) and the simple stop mode (FIG. 5).

When the reading unit 112 of the communication unit 110 reads the mode through the vehicle status signal, the mode transmitting unit 113 transmits the read mode to the idle blocking control unit 130 (S230). At this time, the mode transmission unit 113 of the communication unit 110 transmits the vehicle status signal (which may also include an external control signal) together with the read mode to the idle block control unit 130.

Thereafter, the idle cut control unit 130 receives the mode and the vehicle status signal transmitted from the communication unit 110, and the mode mounting unit 131 mounts the received mode. The display operation unit 132 outputs the mounted mode and the vehicle status signal (which may include an external control signal) through the display 140.

The process of receiving, analyzing, loading and outputting a vehicle status signal from the communication unit 110 and the idling cutoff control unit 130 is repeatedly performed at predetermined intervals (for example, 100 ms units). You can check in real time.

The processes described with reference to FIG. 2 are a general description of a process of reading a mode and outputting the same through a vehicle state signal, and a process of performing idling blocking operation according to the types of modes to be read according to the vehicle state signal and each mode. This will be described in more detail below.

3 is a flowchart illustrating an example of mode reading in accordance with a vehicle status signal in a method of operating an idle limit device according to an exemplary embodiment of the present invention. That is, the details of the process of FIG. 2 are described.

In FIG. 2, when the communication unit 111 of the communication unit 110 receives the vehicle state signal from the vehicle ECU 210, the reading unit 112 compares the vehicle state signal with a preset reference and analyzes it. >.

The reading unit 112 of the communication unit 110 analyzes whether the L-Volt, the B-Volt, the coolant temperature, the speed, the door, the various sensor signals, and the like of the vehicle state signal are all normal.

If the L-Volt is less than a predetermined value (for example, 10 volts) as a result of analysis, the reading unit 112 reads the error mode S360. In addition, if the analysis result B-Volt is less than a predetermined value (eg, 13 volts) <S320>, the reading unit 112 reads in the "error mode" (S360). If the coolant temperature exceeds the maximum value of the preset range (signal relating to the coolant temperature is also received as a voltage, for example, the minimum value of the normal range is 5V and the maximum value can be set to 6V), the reading unit 112 reads in 'error mode' <S360>. If the analysis result shows that the door is open <S320>, the reading unit 112 reads in the "error mode" <S360>. In addition, when it is determined that the sensor is not normal compared to the previously stored criteria for the various sensor signals <S320>, the reading unit 112 reads in the 'error mode' <S360>.

In addition, even if it is determined that the above-described sensor signals are normal (S320), when it is confirmed that a separate error code is received (S330), the reading unit 112 reads the error mode (S360). .

In addition to the above-described example, when one or more vehicle status signals are comprehensively determined and analyzed as abnormal, the reading unit 112 reads the error mode. For example, the engine speed RPM may be excessively high compared to the speed of the vehicle, or the speed may not be greatly reduced even when the brake is kept on for a predetermined time.

On the other hand, as a result of reading by the reading unit 112, it is determined that the above-described sensor signals are normal <S320>, there is no reception of a separate error code <S330>, and the coolant temperature is lower than the minimum value of the preset range (for example, less than 5V). If it is determined (S340), the reading unit 112 reads that the warm-up mode is being warmed up by driving the engine 220 at the beginning of startup.

In addition, if it is determined that the above-described sensor signals are normal <S320>, there is no reception of an error code <S330>, and the coolant temperature is within a preset range <S340> as a result of reading from the reading unit 112, the reading unit 112 reads in the 'idle mode' after completing the preheating process (S370). Of course, in order to read in the idling mode, it must be confirmed that the speed is '0' through the vehicle status signal.

As described above, the process of reading the mode from the communication unit 110 and transmitting it to the idle cut-off control unit 130 is repeatedly performed at a predetermined cycle, and the initial reading after the start is performed in the warm-up mode. When the engine 220 is preheated and the coolant temperature rises and falls within the normal range, it is generally read in the idle mode <S340>.

When the 'error mode', 'warming up mode', and 'idle mode' are read by the reading unit 112 of the communication unit 110 through the process of FIG. 3, the mode transmission unit 113 sets the read mode to idle blocking. The following procedure of FIG. 2 for transmitting to the fisherman 130 and outputting is performed.

As will be described below, in the error mode and the warm-up mode, even if the driver inputs an idle block signal through a gear neutral process, a toggle process of a brake or a clutch, the idle block control unit 130 does not perform the idle block, but only when the engine is in idle mode. Stopping the 220 to perform the idling blocking process. In other words, if an operation to stop the engine arbitrarily in the error mode in which the vehicle is in an abnormal state is performed, the vehicle may be overwhelmed and the engine is not idled. Also, if the engine is idled in the warm-up mode, Since it cannot be preheated, no idling interruption is performed.

4 is a flowchart illustrating an example of mode reading according to speed in the method of operating the idle limiting device according to the embodiment of the present invention.

Prior to the description of FIG. 4, it is assumed that the current state of the vehicle 200 has been subjected to a normal warm-up process once, and the state of mounting the mode and outputting the display 140 through the process of FIG. 2 is normally performed.

The reading unit 112 of the communication unit 110 continuously checks the vehicle status signal, and determines whether the speed of the vehicle 200 exceeds a preset value (for example, 8 km / h).

If it is determined that the speed of the vehicle 200 exceeds the preset value as a result of reading by the reading unit 112 (S420), the reading unit 112 reads the current mode as 'driving mode' <S430>. . The read mode is transmitted to the idle cut control unit 130 via the mode transmitter 113 and is output from the display 140 through the following procedure of FIG. 2.

On the other hand, if it is determined that the speed of the vehicle 200 does not exceed the preset value as a result of reading by the reading unit 112 (S420), the reading unit 112 reads the current mode as 'idle mode'<S440>. do. That is, the warm up process may be completed, the vehicle may be temporarily stopped during driving, or may be in a stopped state after the driving of FIG. 2 to 3. The result read in the idle mode is output from the display 140 through the process of FIG.

5 is a flowchart illustrating an example of a process of stopping and restarting the engine 220 by receiving an idle blocking signal among operating methods of the idle limiting device according to an exemplary embodiment of the present invention.

That is, in the idling mode, the driver can temporarily stop the engine 220 by performing a predetermined operation. Here, in order to distinguish the situation from turning off the ignition completely by turning the ignition key after the driving is completed, the situation in which the idle limit device 100 temporarily stops the engine 220 by the driver performing a predetermined operation in the idling state ' Simple stop '.

First, the idle blocking operation unit 133 of the idle blocking control unit 130 receives the idle blocking signal <S505>. Here, the idling block signal may vary according to the manual transmission and the automatic transmission. In general, the manual transmission may be gear neutral, side brake on, foot brake or clutch toggle operation. On the other hand, in the case of automatic transmissions, the gear neutral, side brake on, and foot brake can be toggled. As a result, the idling cutoff signal is a signal included in the vehicle state signal transmitted from the vehicle ECU 210 through the communication unit 110.

After the idle blocking operation unit 133 receives the idle blocking signal <S505>, it checks the current mode mounted in the mode mounting unit 131 <S510>.

If it is confirmed that the current mode is the idle mode <S515>, the idle cut operation unit 133 stops the engine 220 (S525). That is, by temporarily stopping the engine 220 when the vehicle 200 is stopped while the vehicle 200 is stationary or in a signal waiting state, unnecessary fuel consumption is reduced and carbon emissions are reduced.

Even when the engine 220 is temporarily stopped because it is confirmed that the engine is in idle mode, power is continuously supplied to the idle limit device 100 because the engine 200 is not stopped by the start key. Therefore, the process of the communication unit 110 reading the mode through the vehicle status signal is repeated without continuing.

That is, the communication unit 110 checks that the engine speed is 0 by analyzing the vehicle state signal received from the vehicle ECU 210, and reads in the 'simple stop mode' <S530>. In this way, the mode (simple stop mode) read from the communication unit 110 is transmitted to the idle stop control unit 130 (S535), and the mode mounting unit 131 of the idle stop control unit 130 receives the received mode (simple stop mode). The display operating unit 132 outputs the mounted mode (simple stop mode) and the vehicle status signal through the display 140. Accordingly, the driver may confirm through the display 140 that the idle operation is normally stopped and the engine 220 is normally stopped and is in the simple stop mode through a predetermined operation.

Thereafter, the idle blocking operation unit 133 of the idle blocking control unit 130 checks whether the idle blocking release signal is input <S550>. In other words, when the vehicle 200 is removed or the signal is changed and the vehicle 200 needs to be started, the driver inputs an idle stop release signal through a predetermined operation. In this case, the idling release signal may also vary according to the manual transmission and the automatic transmission. In general, the manual transmission may be a toggle operation of a foot brake or a clutch, and an automatic transmission may be a toggle operation of a foot brake. As a result, the idle stop release signal is also a signal included in the vehicle state signal transmitted from the vehicle ECU 210 through the communication unit 110.

If it is confirmed that the idle blocking release signal is input by the idle blocking operation unit 133 (S555), the idle blocking operation unit 133 restarts the engine 220 (S560). Of course, if the engine 220, which is temporarily stopped, is not restarted immediately after restarting (S560), the communication unit 110 goes through the reading process of FIGS. Will be.

On the other hand, even when the idle cut signal is received, in the warm-up mode, the error mode, the external control mode, the travel mode, and the simple stop mode other than the idle mode, the idle stop operation unit 133 of the idle stop control unit 130 is the engine stop function. In this case, the display operation unit 132 outputs the engine stop impossible information through the display 140 to allow the driver to check why the idling blocking function is not performed.

Anyway, in the present invention, since the user can check the current mode of the vehicle 200 through the display 140 in advance, the driver checks the output through the display 140 before performing the operation for blocking the idling. I will not try to stop idle.

In this case, the idle stop signal input in the simple stop mode may be the same as the idle stop release signal (foot brake, toggle of the clutch) according to the situation, so that the stopped engine 220 may be restarted again.

6 is a flowchart illustrating an example of a process of determining an external control mode in an operating method of an idle limit device according to an exemplary embodiment of the present invention.

That is, the process up to FIG. 5 has been described in which the mode is read through the vehicle state signal and the idling blocking operation is performed according to the mode. However, in the present invention, not only the vehicle status signal received from the vehicle ECU 210, but also the external control unit 120 analyzes the inclination, position, time, etc. of the vehicle 200 to prohibit idling blocking or forced blocking. It may be. An example of analyzing such an external control mode is shown in FIG.

After the analysis of the mode according to the vehicle status signal and the output process through the display 140 (or the external control analysis process may be performed at the same time) through the process of Figure 2, the external control analysis unit 123 of the external control unit 120 ) Receives the inclination information from the inclination sensor 121, receives coordinate information and time information from the GPS receiver 122, and performs external control analysis through this.

If it is determined that the inclination of the vehicle 200 is greater than or equal to the set value (10 degrees) <S620>, the external control analysis unit 123 generates external control analysis result information indicating that 'external control mode-tilt' to communicate. Transmit to the unit 110. This will be described with reference to FIG. 7.

On the other hand, the slope of the vehicle 200 is normal (less than 10 degrees) as a result of analysis, but as a result of analysis through coordinate information and time information, the vehicle 200 is forbidden to block idling at a specific location in a specific time zone. If it is determined to be <S630>, the external control analysis unit 123 generates external control analysis result information indicating that 'external control mode-no idling blocking' and transmits it to the communication unit 110. This will be described with reference to FIG. 8.

Also, as a result of the analysis, the inclination of the vehicle 200 is normal and is not prohibition of idling blocking. However, as a result of analyzing the coordinate information and time information, the vehicle 200 forces idling at a specific position. If it is determined that the situation is to be blocked <S640>, the external control analysis unit 123 generates external control analysis result information indicating that the 'external control mode-idle forcing blocking' and transmits it to the communication unit 110. This will be described with reference to FIG. 9.

Of course, if the slope is also normal and not in a specific position, it is not an external control situation. Therefore, only the mode analysis through the vehicle status signal is performed through the process of FIG. 2.

7 is a flowchart illustrating an external control mode due to the inclination of the vehicle 200 in the method of operating the idle limit device according to the embodiment of the present invention.

That is, when it is determined that the inclination of the vehicle 200 is greater than or equal to the set value (10 degrees) by the external control analysis unit 123 of the external control unit 120 through the process of FIG. 6, the external control analysis unit 123 ) Generates external control analysis result information indicating that the 'external control mode-tilt' is transmitted to the communication unit 110 (S710). At this time, the external control analysis unit 123 transmits an external control signal including tilt information, coordinate information (position information) and time information acquired by the tilt sensor 121 and the GPS receiver 122 to the communication unit 110. You can also send them together.

Thereafter, the reading unit 112 of the communication unit 110 refers to the external control analysis result information transmitted from the external control analysis unit 123 and reads it as 'external control mode-tilt' <S720>, and transmits the mode transmission unit ( 113 transmits the read mode (external control mode-tilt) to the idle blocking control unit 130, and the mode mounting unit 131 of the idle blocking control unit 130 receives the mode (received from the communication unit 110). The external control mode-tilt) is mounted in the current mode (S740), and the display operation unit 132 outputs the mounted mode, the vehicle status signal, the external control signal, and the like through the display 140 (S750).

If the driver receives the idling cutoff signal from the idling cut-off control unit 130 by performing a predetermined operation in this state <S760>, the idling cut-off process is performed or impossible by going through the process shown in FIG.

Of course, since the current mode is mounted as 'external control mode-tilt' through the process of FIGS. 6 to 7, even if the idling cutoff signal is input <S760>, the engine stop does not occur, and the engine stops through the display 140. No information will be output.

That is, even if the idling condition is satisfied through the vehicle status signal, if the engine 220 is stopped when the vehicle 200 is stopped at an inclined position, there is a high possibility that problems such as brake malfunction may occur. An accident may occur. Therefore, in the present invention, when the vehicle 200 is inclined, the external control mode is mounted so that no idling blocking operation occurs. In addition, the driver is idle idly by notifying in advance through the display 140 that the external control mode (tilt) is present. It is possible to prevent attempts at blocking operations.

8 is a flowchart illustrating an external control mode for prohibiting idle shutdown in the method of operating the idle limit device according to the exemplary embodiment of the present invention.

That is, the slope of the vehicle 200 in the external control analysis unit 123 of the external control unit 120 through the process of Figure 6 is normal (10 degrees or less) <S620>, but analyzed through the coordinate information and time information As a result, if the vehicle 200 is determined to be in a situation where the idling is prohibited in a specific position in a specific time period <S630>, the external control analysis unit 123 indicates an external control analysis result indicating that 'external control mode-no idling blocking'. The information is generated and transmitted to the communication unit 110 (S810). At this time, the external control analysis unit 123 transmits an external control signal including tilt information, coordinate information (position information) and time information acquired by the tilt sensor 121 and the GPS receiver 122 to the communication unit 110. You can also send them together.

Thereafter, the reading unit 112 of the communication unit 110 refers to the external control analysis result information transmitted from the external control analysis unit 123 and reads it as 'external control mode-do not block', and transmits the mode. The unit 113 transmits the read mode (external control mode-no idling blocking) to the idling cut-off control unit 130, and the mode mounting unit 131 of the idling cut-off control unit 130 is transferred from the communication unit 110. The received mode (external control mode-no idling blocking) is mounted in the current mode <S840>, and the display operation unit 132 outputs the mounted mode, the vehicle status signal, the external control signal, etc. through the display 140. S850>.

If the driver receives the idling cutoff signal from the idling cut-off control unit 130 by performing a predetermined operation in this state <S860>, the idling cut-off process is performed or impossible by going through the process shown in FIG.

Of course, since the current mode is mounted as 'external control mode-no idling blocking' through the process of FIGS. 6 and 8, even if the idling blocking signal is input <S860>, the engine is not stopped and the display 140 is performed. No engine stop information will be output.

In the 'external control mode-no idling blocking' state, the idling blocking is not possible because the engine 200 must be repeatedly stopped and restarted at a certain time in a certain time zone, so that the vehicle 200 consumes a lot of fuel, rather it consumes fuel. Is more likely to cause malfunctions.

For example, Gangnam-daero during the rush hour, there may be a long signal wait or stop at a time, but in most cases it is more than 10-20km / h per hour. In this situation of repeatedly standing and standing, when the vehicle stops temporarily to satisfy the idling condition, if the engine 220 is simply stopped unconditionally, the engine 220 must be restarted within a few seconds.

That is, simply stopping the engine 220 through the idling limiter 100 reduces fuel consumption by preventing unnecessary idling, but the fuel consumed when the engine 220 is restarted is about 10 seconds to 15 seconds of idling. Corresponds to consumption. Therefore, the simple stopping of the engine 220 when the vehicle is stopped within 15 seconds returns to the adverse effect rather than continuously idling.

In addition, the operation of inputting the idling blocking signal is a toggle operation of the brake or clutch (although there may be a condition of gear neutrality), and if the driver repeatedly stands and releases the brake repeatedly, the driver unintentionally idles. A cutoff signal can also be input. That is, in the conventional idling limit device without the idling blocking through the external control mode, the engine 220 may be easily stopped even if the driver does not intend it.

However, in the present invention, even if the idle control condition is satisfied and the idle stop signal is input in a specific section in which the external control unit 120 goes through the position and the time information repeatedly, the engine 220 is frequently blocked by the idle operation. This prevents problems such as adverse effects and unintended engine stoppages that can occur by restarting the engine.

In addition, by notifying the display 140 of the current external control mode (no idling blocking), the driver may be prevented from forcibly attempting the idling blocking operation.

9 is a flowchart illustrating an external control mode forcibly interrupting idling in the method of operating the idling limiter according to the exemplary embodiment of the present invention.

That is, the slope of the vehicle 200 is normal in the external control analysis unit 123 of the external control unit 120 through the process of FIG. 6 and is not prohibited. As a result of analysis through the information, if the vehicle 200 is determined to be in a situation in which it is necessary to forcibly block idling at a specific position <S640>, the external control analysis unit 123 indicates that 'external control mode-idle forced blocking'. The external control analysis result information is generated and transmitted to the communication unit 110 (S910). At this time, the external control analysis unit 123 transmits an external control signal including tilt information, coordinate information (position information) and time information acquired by the tilt sensor 121 and the GPS receiver 122 to the communication unit 110. You can also send them together.

Thereafter, the reading unit 112 of the communication unit 110 refers to the external control analysis result information transmitted from the external control analysis unit 123, and reads it as 'external control mode-idle forcing blocking', and transmits the mode. The unit 113 transmits the read mode (external control mode-idle forced block) to the idle block control unit 130, and the mode mounting unit 131 of the idle block control unit 130 is separated from the communication unit 110. The received mode (external control mode-idle forced blocking) is mounted in the current mode <S940>. In addition, the display operation unit 132 may output the mounted mode, the vehicle status signal, the external control signal, and the like through the display 140.

In addition, the idling blocking operation unit 133 of the idling blocking control unit 130 checks whether the idling blocking condition is satisfied according to the vehicle status signal transmitted from the vehicle ECU 210 through the communication unit 110.

Satisfying the idling cutoff condition is a condition that satisfies the 'idling mode' during the above-described process and at the same time does not cause any abnormality even if the idling is forcibly cut off (eg, speed 0, accelerator pedal signal off, gear neutral, side brake on, etc.). , And that the passage of time (eg 30 seconds) of idling is satisfied.

When it is confirmed that the idling blocking condition is satisfied <S960>, the idling blocking operation unit 133 of the idling blocking control unit 130 stops the engine 220 briefly <S970>.

At this time, the simple stop at the time of 'external control mode-idle forced shutoff' performed through the process of FIG. 9 and the idle stop signal input by the driver performed through the process of FIG. 5 are the same as the engine stop. But the cause is different.

That is, in FIG. 9, idling is forcibly cut off without an idling signal input by the driver. This is determined when the vehicle 200 is located at a specific position through the process of FIG. For it was built. For example, in a parking lot, a garage, etc., the driver may leave the seat for a long time after turning the ignition key to preheat the engine 220. The engine 220 preheating process varies depending on the type of vehicle 200 and the season, but usually two minutes or less is sufficient. However, even if the display 140 outputs that the warm-up mode is in the idle mode after entering, the driving or idle blocking process cannot be made if the driver is away. Therefore, even if the idle limit device 100 is installed, there may be a case where the idle situation persists.

Therefore, in the present invention, by analyzing the location information received through the GPS receiver 122 from the external control unit 120, the vehicle 200 is idle for a predetermined time (for example, a garage or a parking lot, not a road) for a predetermined time (for example, 30). Second), and if the idle stop condition is satisfied, even if there is no intentional operation of the driver, the engine 220 is forcibly stopped by preventing the unnecessary idle situation to maximize the device use efficiency.

On the other hand, after the simple stop of the engine 220 through the process of Figure 9 (S970), as shown in Figure 5, the communication unit 110 reads in the simple stop mode through the vehicle status signal <S530> and outputs through the display 140 The following process may be performed.

6 to 9, inclination information, coordinate information, and time information are analyzed by the external control analysis unit 123 of the external control unit 120, and the analyzed external control analysis result information is communicated with the communication unit 110. Although it is described that the reading unit 112 can read whether the control unit 112 is in the external control mode by transmitting to the external control unit 120, the external control unit 120 does not include a separate external control analysis unit 123, and the tilt sensor 121 is performed. ), By transmitting the tilt information, coordinate information, and time information obtained only with the GPS receiver 122 to the communication unit 110, the reading unit 112 of the communication unit 110 is inclined information with the vehicle status signal, The coordinate information and time information may be combined and analyzed to read out the external control mode. Of course, in this case, the reading unit 112 of the communication unit 110 compares the slope information, the coordinate information, and the time information with reference information stored in a separate storage device (not shown) to read whether the external control mode.

In addition, in the above description, it is described that the current time is received through the GPS receiver 122, but in accordance with the implementation, a watch (not shown) mounted on a vehicle or a watch (not shown) separately mounted on the device may be used. It can also be implemented to check the current time.

As described in detail above, according to the present invention, the communication unit 110 receives the vehicle status signal from the vehicle ECU 210, analyzes it, reads the mode, and mounts the read mode in the idle cut control unit 130. By doing so, even when there is an operation of the driver for the idling cutoff, the idling cutoff is not performed when the driver is not in the idling mode, thereby preventing the vehicle 200 from becoming excessive.

In addition, by outputting the mounted mode and the state of the vehicle 200 through the display 140, the driver may check whether the current vehicle state may be attempted for the idling cutoff by checking the current vehicle status in real time. If the idle operation is not blocked even though the operation is performed, you can check why the operation was not performed.

For example, the driver who cares much about his vehicle 200 believes that the more the preheating is better, the more fuel waste and carbon emissions due to the excessive preheating process, but as in the present invention, when the preheating (warming up) process is completed, The idle mode may be output through the display 140 to inform the driver so that unnecessary idling is not achieved. On the other hand, the vehicle 200 may be unreasonable by attempting the idling blocking operation without knowing whether there is an error in the state of the vehicle, but if the vehicle 140 is confirmed to be in the error mode, the idling blocking operation may not be attempted in the first place. Satisfaction for drivers who care about 200) can be further enhanced.

In addition, by storing and outputting the vehicle status, the number of idle shutdowns, fuel savings, and carbon emission savings, the driver can feel the benefits of using the device and inspire the user to use the device more and more. As a result, it is possible to create a virtuous cycle structure that further increases fuel savings and carbon emission reduction effects.

In addition to the vehicle status, if the vehicle 200 is inclined (that is, hill) in the stopped state, it is possible to further increase the safety by preventing idling blocking, or when the vehicle 200 is in a specific position at a specific time period. It is possible to increase the convenience by disabling idle stop even in the case of frequent slowing and stopping, or to save fuel by forcibly stopping idle without the driver's operation in a specific location (eg garage). It can further reduce the carbon emissions.

Meanwhile, in the case of 'external control mode-no idling blocking' or 'external control mode-forced idling' described above, the driver may be considered as a function that is not required, and therefore, whether the driver uses the mode or not It may be implemented to select through a switch (not shown) of.

The foregoing description of the preferred embodiments of the present invention has been presented for the purpose of illustration and it will be apparent to those skilled in the art that various modifications, additions and substitutions are possible within the spirit and scope of the invention, And additions should be considered as falling within the scope of the claims of the present invention.
