An idling prevention system and method using a telematics unit that saves energy, prevents asphyxiation in confined areas, and also complies with regulations.

It is desirable to prevent unnecessary idling because idling of a vehicle that drivers are habitually not only wastes energy, but also causes asphyxiation in airtight spaces and causes air pollution. However, the conventional vehicle has no means of preventing the idle or telling the driver to idle more than necessary unless the driver himself recognizes and is careful.

Furthermore, drivers are required to apply unnecessary fines by enforcing idle idling in public places such as terminals, parking lots, garages, car theatres, stadiums, etc. Since there is a high possibility of being claimed, there is a need for a means to block the vehicle from idling or to perform idling only for a set time.

SUMMARY OF THE INVENTION The present invention has been made to solve the above requirements, and an object of the present invention is to transmit a vehicle position and state data (temperature) to a server using a telematics unit, and determine whether the vehicle position is an idle limit zone by the server.

Limiting idling; and 2) limiting idling by receiving idling time limit by predicting the position of the vehicle when the idling condition is detected as the GPS signal is not received and telematics communication is enabled. When the idle state of the vehicle is detected in a state that is not received and the telematics communication is impossible, it characterized in that it comprises a step of limiting idle using the set idle time limit.

Hereinafter, an idling prevention system and method using the telematics unit of the present invention will be described in detail with reference to the accompanying drawings.

The present invention is to prevent idling of the vehicle or to perform idling only for an allowable time. The telematics unit having a wireless communication function is used to display the current location and state data of the vehicle (telematics). When transmitting to the server, the server receives a signal, and whether the idling is restricted zone and the idling limit signal (including time) by transmitting to the vehicle, the idling prevention system and prevention method that can stop idling within the time limit.

The installation state as described above may be changed depending on the type of the vehicle. Reference numeral 90 denotes a controller control stop switch for forcibly disabling an idle prevention function.

Figure 2 is a block diagram of the idle prevention system of the present invention, using the GPS signal to transmit the vehicle position and status data to the server, idle limit zone information, idle limit signal and time limit, GPS signal reception and server from the server A telematics unit 20 for transmitting a communication state to the controller 40 and indicating that the vehicle is a restricted area, a vehicle speed sensor 50 for detecting a vehicle speed, an engine motion detection unit 30 for detecting whether the engine is operating, and The temperature sensor 60 detects the temperature around the engine, and detects whether the vehicle is parked or not, and determines whether to transmit the current vehicle position and status data to the server. The controller 40 for limiting the idling of the vehicle by using the time limit, the power switch breaker 70 for controlling the power switch 80 on / off, and the telematics unit 20 Determines the idling restriction zone using the vehicle location information transmitted from the vehicle. If the idling restriction zone is determined, the idling time is determined by using the status data and the model data, and if the telematics communication is possible and the GPS signal cannot be received, The server 100 may determine and determine whether the expected stop area and the restricted location are based on the final position of the vehicle, and set and transmit the restriction signal and the time limit using the idling restricted zone information, the state, and the model data.

The telematics unit 20 is mounted on a vehicle and includes a wireless transmission / reception function through the antenna 10, and detailed functions and configurations thereof are known in the art, and thus description thereof will be omitted. In the present invention, the telematics unit 20 is used to wirelessly transmit and receive specific data, and also displays received data (data related to idle limit) through an LCD display window (not shown) installed in the telematics unit 20. It is used to

The controller 40 may be configured using a one-chip microcomputer in which a control program and control data for controlling an idle prevention system of the present invention are embedded and a memory device is connected. The controller 40 is also connected to the telematics unit 20 to transmit the necessary data and to read the received data. The detailed operating state of the controller 40 will be described later.

The vehicle speed sensor 50 is for detecting a moving state of the vehicle. When the vehicle speed is "0", it means a stop state. However, since this does not mean the idle state, in the present invention, the engine operation detection unit 30 detects the operation state of the engine, and further obtains the current position information of the vehicle (road or non-road area) by using GPS. It is judged whether the idle state.

The temperature sensor 60 is for detecting the state data (temperature) used to determine the idling time during idling of the vehicle. The temperature sensor 60 is installed at the front end of the engine room of the vehicle to detect the temperature and transfer the detected temperature data to the controller 40. The controller 40 finally transmits the temperature state data to the telematics server 100 using the telematics unit 20.

The power switch breaker 70 is connected to the middle of the wiring of the power switch 80 is used to forcibly stop the engine by stopping the engine by cutting off the power. The power switch breaker 70 is controlled on / off by the control signal of the controller 40.

The telematics server 100 determines whether a specific vehicle is located in an idling restricted area by using the position and state data of the vehicle transmitted from the telematics unit 20. It is for transmitting information. The operating state of the telematics server 100 is shown in FIG. 4 and will be described later.

An idle prevention method of the present invention performed using the idle prevention system configured as described above is shown in FIGS. 3A-3C. 3A-3C essentially constitute a flowchart, but are separated for convenience of description.

In the idle prevention method of the present invention, 1) the GPS signal is received and the telematics communication is possible, the vehicle is located in the idling restriction zone and the idling state is detected when the idling state is detected, and the idling is limited, and 2) the GPS signal When the vehicle is not received and the telematics communication is detected and the idle state is detected. If is detected includes the step of limiting idle using the set idle timeout, and includes a subdivided step for each step.

First, when the GPS signal is received and the telematics communication is possible and the vehicle is located in the idling limit zone and the idling state is detected, the step of limiting idling by receiving the idling time limit is as follows.

A first step of detecting a GPS signal, a vehicle speed, and an engine operating state by determining that the vehicle is at an off-road area, a vehicle speed of "0", and determining the idling time at the same time when the engine operation condition is satisfied; A second step of transmitting vehicle position and ambient temperature (state) data to a server using a telematics unit; A third step of determining whether the vehicle is stopped in the restricted area by receiving the idle limited area information, whether to stop in the restricted area, or the idle time limit T1 from the server; A fourth step of determining whether to maintain the idling stop state when the vehicle is stopped in the restricted area; And a fifth step of displaying an alarm sentence until the idle time limit is reached by the controller when the idle stop state is maintained, and stopping the engine by operating the power switch breaker when the time limit is reached.

Referring to step 1) as described above in detail.

When the vehicle is turned on, the controller automatically starts interlocking with the telematics unit. In this state, GPS signal reception and telematics communication are possible. While receiving the GPS signal, the controller determines vehicle position (GPS) information, vehicle speed information, and engine operation through the engine operation detection unit (ALT 'L' terminal). The current vehicle is located in an area other than a road, and the vehicle speed is '0' (stop) and the engine is in operation.

If these three conditions are met at the same time, the controller determines the idle stop state, counts the internal clock, and controls the telematics unit to transmit the current vehicle position information and ambient temperature status data to the telematics server.

Using the transmitted data, the telematics server searches the map DATABASE (preliminarily created and stored in the server) to determine whether the vehicle position is at idle limit. As a result of the search, if the place where the vehicle is located is the idling limit, the idling time according to the law is set using the ambient temperature state data of the vehicle.

The telematics server transmits idle limit zone information, idle limit signal (stopping or not in the restricted zone), and time limit to the telematics unit mounted on the vehicle for displaying the screen in the telematics unit. If it is not an idling restriction zone, it does not authorize information such as time limit and transmits only screen display data that it is not idling restriction zone.

When the data is received from the server as described above, the controller displays the idle limit zone, idle limit time, and current elapsed time on the NAVIGATION screen.

Then, the GPS signal is analyzed by analyzing the GPS signal (whether or not out of the idling limit area), moving the vehicle through the speed detection, and determining whether the engine is stopped through the engine motion detection unit (ALT 'L' terminal). When leaving the restricted area or moving the vehicle, it returns to the initial standby state, and when the engine stops, the control ends. The end of the engine is a case where the driver ends the engine.

However, when the above condition is not satisfied in the "no change" state, it is determined that the vehicle remains in the idling stop state, and the controller performs the next operation. That is, based on the current elapsed time (t), the time limit (T1) and the alarm (operation reference) time (X), if the elapsed time is before the alarm time, it is displayed on the screen and the vehicle status change (via the GPS signal) Continuously monitor the deviation of the idling limit zone, moving the vehicle, and stopping the engine. Also, during alarm time, alarm action (warning phrase display, alarm sound, etc.) is executed.

If the elapsed time t is before the time limit T1, the controller control stop (OFF) command can be accepted. When the OFF operation is made, the control of the controller is stopped and the system is terminated. When the elapsed time t is equal to the time limit T1, the engine is stopped by cutting the wiring of the power switch by controlling the power switch breaker connected to the controller to cut off the idling.

In addition, 2) when the GPS signal is not received and the telematics communication is possible and the idling state is detected, the step of predicting the position of the vehicle and receiving the idling time limit to limit the idling is as follows.

When telematics communication is performed in the state that GPS signal is not received, the controller detects the vehicle speed and the engine operation state. If the vehicle speed is "0" and the engine operating condition is satisfied at the same time (and operation), it is judged as idling and the stop time is A sixth step of counting; A seventh step of transmitting the final vehicle position and ambient temperature state data to the server using the telematics unit; An eighth step of determining whether the vehicle is stopped in the restricted area by receiving the idle limit zone information, whether the vehicle is expected to stop at the idle stop, and the idle time limit T2 from the server; A ninth step of determining whether to maintain the idling stop state by detecting the vehicle speed and the engine operating state if the vehicle is stopped in the restricted area, and moving to the twelfth step of determining that the vehicle is in a closed place when the vehicle is stopped outside the restricted area; And a tenth step of displaying an alarm sentence until the idle time limit is reached by the controller when the idle stop state is maintained, and stopping the engine by operating the power switch breaker when the time limit is reached.

Referring to step 2) as described above.

In the second step, the GPS signal is not received but the telematics communication is possible. In this case, the GPS signal does not receive the GPS signal and does not check whether it is a road or an area other than the road. The telematics unit and the server can be considered to be a place where a dedicated communication antenna is installed in a communicable state or a communication wave is received through diffraction. When the vehicle is located near the entrance of the indoor or underground space and the GPS signal is not received or the communication wave is received, the vehicle speed = '0' excluding the GPS signal is detected and the engine operation is detected to determine the idling stop state.

In the idle stop state, the controller starts counting the stop time, and transmits the finally recognized vehicle position and ambient temperature state data to the server through the telematics unit. The server determines whether or not the expected parking area (indoor, underground space, etc.) is an idle limit zone based on the last recognized vehicle position.

When the final recognized location of the vehicle is an indoor, underground entrance or no idling zone, the telematics server sets idling restricted zone information, whether to stop in a restricted zone, and idling time limit and transmits it to the telematics unit 20.

However, if the anticipated area where the vehicle is located is not at the idling limit, move to step 12. In other words, if it is not in the idling limit zone, the time limit is not allowed. If it is determined that the vehicle is located in the restricted zone, the controller uses the data transmitted from the server to inform the driver that the stop zone is the idle limit zone and display the idle time limit and the elapsed time through the navigation screen.

Also, if GPS signal is received or not, the output check of the vehicle speed sensor and engine motion detection unit (ALT 'L' terminal) checks whether the GPS signal is received, whether the vehicle is moving (measurement of speed), or the vehicle is moved. When it is determined that the engine is in the idle state and the idle stop state is maintained, the controller performs the following operation.

That is, when the elapsed time is earlier than the alarm time based on the current elapsed time (t), the time limit (T2), and the alarm (operation reference) time (X), it is displayed on the screen and the vehicle status change (via the GPS signal) Continuously monitor the deviation of the idling limit zone, moving the vehicle, and stopping the engine. Also, during alarm time, alarm action (warning phrase display, alarm sound, etc.) is executed.

When the elapsed time t is equal to the time limit T2, the engine is stopped by cutting the wiring of the power switch by controlling the power switch breaker connected to the controller to cut off the idling.

3) If the idle signal of the vehicle is detected in the state in which the GPS signal is not received and the telematics communication is impossible, the step of limiting the idle speed using the set idle time limit is as follows.

When the GPS signal is not received and the telematics communication is not performed, the vehicle speed and the engine operating state are detected, and when the vehicle speed is "0" and the engine operating condition is satisfied (and operation), it is determined as idling and the stop time is counted. step; Determining a position of the vehicle as a closed space and setting an idle limit time T3; A thirteenth step of determining whether to maintain the idling stop state by detecting a GPS signal not received, the vehicle speed, and an engine operating state; And a fourteenth step if the idle stop state is counted by the controller to display an alarm message until the idle time limit is reached, and when the time limit is reached, the power switch breaker is operated to stop the engine.

Referring to step 3) as described above are as follows.

In step 3), the GPS signal is not received and the telematics communication is not possible, which corresponds to an indoor or underground space (communication antenna installation). That is, it is determined that the communication state between the telematics unit and the server is a communication incapacity state where no communication dedicated antenna is installed. In this case, vehicle speed = '0' except the GPS signal, and engine operation is detected to determine the idling stop state.

If it is determined that the vehicle is idle, the controller starts counting the stop time. The controller then informs the screen that the stop area is now enclosed and displays a predetermined idle time limit (T3) and elapsed time. In this case, since it is impossible to transmit or receive to the server, it uses data embedded in the controller itself.

When receiving GPS signal through GPS signal reception, vehicle speed sensor, engine operation detection unit (ALT 'L' terminal), GPS signal reception, vehicle movement check (vehicle speed measurement), engine operation status, or When the vehicle moves, it returns to the initial standby state and terminates the system control when it is determined that the start is turned off.

However, judging that the vehicle remains in the idle stop state by determining the idle stop state, the controller performs the following operation. That is, when the elapsed time is earlier than the alarm time based on the current elapsed time (t), the time limit (T1) and the alarm time (X), the screen display is performed and the vehicle status change (idle limit area through the GPS signal) is performed. Continuity, vehicle movement, engine stop) Also, during alarm time, alarm action (warning phrase display, alarm sound, etc.) is executed.

However, in step 3), whether the controller control stop switch 90 is inputted is ignored because it is an expected closed area to prevent suffocation. When the elapsed time t is equal to the time limit T3, the controller controls the power switch breaker to stop the engine by cutting off the wiring connected to the power switch.

On the other hand, the operating state of the telematics server 100, referring to Figure 4, as follows. In the telematics unit 20, the GPS reception possible state, the communication between the telematics unit 20 and the server 100, the server 100 based on the vehicle position and the state data received from the telematics unit 20, the idling limit place In case of idling limit, determine time limit using ambient temperature status data and vehicle type (fuel).

In addition, when the GPS reception of the telematics unit 20 is impossible, and the communication between the telematics unit 20 and the server 100 is possible, the telematics server is unable to receive the GPS signal of the telematics unit 20 (wave weakness / shielding). Therefore, when the final position is transmitted, it is determined whether it is the expected stop area and the idling limit area determined based on the final position, and the time limit is determined based on the idling limit zone information, the ambient temperature status data and the vehicle type (fuel used). In each case, the idling limit signal is not transmitted when the idling area is outside the idling limit place.

The reason for putting idling restricted area in the server is because the update of the server affects the entire serviced vehicle (prompt response to the change of restricted area and time limit). In addition, the server can perform accurate response according to the law by including the information on the fuel used in the registered vehicle. In addition, idling restricted zone information is stored on the same map as the NAIGATION MAP of the vehicle.If the current position of the vehicle is within the idling restricted zone, the restricted zone information is transmitted and the current position of the vehicle and the restricted zone overlap the vehicle's NAVIGATION. Can be displayed.

According to the present invention as described above, the vehicle position and status data (temperature) are transmitted to the server using a telematics unit, and the server determines whether the vehicle position is an idle limit zone, and transmits an idle limit signal if the restricted zone is idle. This can save energy, prevent asphyxiation in confined areas, and comply with regulations.
