Abstract

The present invention relates to an apparatus and method for idling a vehicle, and more particularly, to a method and apparatus for idling a vehicle by turning off the vehicle after a certain period of time without a driver turning off the engine, if the driver judges that the vehicle is parked in an idling- And more particularly, to an idle vehicle idle stop device and method for minimizing idle idling of a vehicle.

Description

FIELD OF THE INVENTION [0001] The present invention relates to an idling-

The present invention relates to an apparatus and method for idling a vehicle, and more particularly, to a method and apparatus for idling a vehicle by turning off the vehicle after a certain period of time without a driver turning off the engine, if the driver judges that the vehicle is parked in an idling- And more particularly, to an idle vehicle idle stop device and method for minimizing idle idling of a vehicle.

Recently, automobile exhaust gas, which is known to increase fine dust and ultrafine dust, is becoming a main cause of environmental pollution.

Particularly, the exhaust gas increases as the fuel is incompletely burned when idling the vehicle. Generally, idling occurs when the vehicle is stopped while the vehicle is started.

In recent years, an idling restriction device and a control method have been developed and applied to vehicles in order to reduce the emission of exhaust gas by idling of such vehicles.

In order to detect the idling condition, the idling limit is restricted by idling the engine when the brake pedal is depressed and the vehicle speed is 0, and then the driver's willingness to drive is judged by pressing the accelerator pedal And then start the vehicle again so that the vehicle can move.

Further, the other idling restriction device turns off the engine when it is determined that idling occurs for a predetermined time or more in the parking state.

However, the conventional idling restriction device operates uniformly without consideration of other parts of the vehicle, operating conditions, location, and the like, so that there is a problem that the engine may be stopped in a dangerous situation or in a situation where engine operation is required.

Further, the conventional idling restriction device may have started the idling restriction device if necessary even if idling occurs for a predetermined time or more in the parking state. However, the conventional idling restriction device will not be able to reflect the situation in which the driver intentionally starts the engine, and the engine will be turned off immediately. That is, the conventional idling restriction device can not reflect the user's intention.

Hereinafter, the method for interrupting the designated area idling by the controller 60 will be described in detail with reference to FIGS. 2 and 3. FIG.

2 is a flowchart illustrating a method for interrupting idling of a designated area according to the present invention.

Referring to FIG. 2, the control unit 60 starts collecting vehicle status information through the vehicle condition measurement unit 20 when power is supplied to the vehicle (S111).

When the vehicle status information is collected, the control unit 60 determines whether the vehicle is running or stopped based on the collected vehicle status information (S113).

If it is determined that the vehicle is traveling, the control unit 60 sets the running flag to a set (S115), switches to the traveling experience mode, and performs an operation according to the traveling experience mode (S117). The operation according to the traveling experience mode will be described in detail with reference to FIG. 3 to be described later.

On the other hand, if it is determined that the vehicle is stopped, the control unit 60 checks the driving flag of the storage unit 10 to determine whether the vehicle is set to the reset state (S119).

If the driving flag is set to three, the control unit 60 determines that the vehicle has stopped for a while. If the driving flag is set to reset, the control unit 60 analyzes the vehicle state information continuously collected to determine whether the parking brake is driven (S121).

If it is determined that the parking brake is activated, the control unit 60 performs a driver detection operation to determine whether there is a driver in the vehicle through the driver detection unit 30 (S123).

When the driver detection operation is performed, the controller 60 analyzes the driver detection information input from the driver detection unit 30 to determine whether the driver is not detected (S125). That is, the control unit 60 determines whether or not the driver is aboard the vehicle.

As a result of the determination, if there is no driver in the vehicle, the control unit 60 starts counting the driver's boarding time (S127).

When the driver's boarding time starts counting, the controller 60 checks whether the counted driver's boarding time exceeds the reference time, and determines whether the counted time exceeds the reference time (S129).

If the predetermined time is exceeded, the control unit 60 controls the engine driving unit 50 to stop the engine and to block the idling (S135).

According to another embodiment of the present invention, the control unit 60 collects area information through the area detecting unit 30 when the driver's boarding time exceeds a predetermined time (S131), analyzes the collected area information, (S133). If it is determined that the current area is a parking designation area, the control unit 50 controls the engine driving unit 50 to determine whether the current area is the parking specifying area, (S135). At this time, the area information output from the area detection unit 40 is preferably position information output by the GPS module 42, and the parking specification area information also preferably includes position information.

3 is a flowchart illustrating a method for interrupting idling of a specified area in a traveling experience mode according to the present invention.

Referring to FIG. 3, when the driving experience mode is set, the controller 60 measures and stores the illuminance through the illuminance measuring unit 41 of the area detecting unit 40 (S211).

When the illuminance is measured, the controller 60 compares the measured illuminance and the previous illuminance to calculate the illuminance variation (S213), and determines whether the calculated illuminance variation is greater than or equal to the reference variation amount (S215).

If it is determined that the calculated amount of change in illumination has exceeded the reference change amount, the control unit 60 regards the vehicle as having entered an idling restriction area such as a closed parking lot with low illumination and the like and detects it in the vehicle speed detection unit 21 of the vehicle condition measurement unit 20 The travel time and the travel distance are measured based on the vehicle speed information, and the measured travel time and travel distance are accumulated and stored (S217).

When the driving time and the driving distance start to be accumulated, the control unit 60 determines whether or not the driving distance is stored within the stored driving distance and the parking determination preset distance in the storage unit 10 (S219, S221).

The control unit 60 determines that the vehicle has stopped in the idling restriction zone when it is considered that the idling restriction zone has been entered, and then, if the vehicle stops within the set parking determination distance, performs the parking preliminary determination (S221). However, if the calculated mileage does not stop until it exceeds the parking determination setting distance, it is determined that the vehicle has passed through the shadow area, and the continuous luminance variation is monitored.

When the parking preliminary determination is made as described above, the control unit 60 checks whether the vehicle stops from the vehicle speed information of the collected vehicle state information (S223). If it is determined that the vehicle has stopped, Is driven (S225).

When the parking brake is activated, the control unit 60 activates the driver detection unit 30 to perform driver detection in the vehicle (S227) after setting the running flag to reset (S226).

When the driver detection is performed, the controller 60 determines whether the driver is not detected through the driver detection unit 30 (S229). That is, the control unit 60 determines whether or not the driver has got off the vehicle.

When a driver is detected in the vehicle, the controller 60 determines whether the driver's undetected flag is set to a set value (S231). If the driver's undetected flag is set to 3, the driver's undetected flag is reset, After one (S233), the driver detection operation is repeatedly performed (S227).

On the other hand, if it is determined that the driver is not detected in the vehicle, the controller 60 sets the driver undetected flag to 3 and sets the parking of the vehicle (S235), and then counts the driver's boarding time (S237) .

When the driver's boarding time starts counting, the controller 60 checks whether the counted driver's driving time has exceeded a predetermined first time (S239). If the driver's boarding time exceeds the first time, (50) to stop the engine (S241).
