BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

It should be understood that the specific details of the invention are set forth in the following description to provide a more thorough understanding of the present invention and that the present invention may be readily practiced without these specific details, It will be clear to those who have knowledge.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to FIGS. 1 and 2, and a description will be given centering on parts necessary for understanding the operation and operation according to the present invention.

FIG. 1 is a view for explaining a dark current cutoff control system for a vehicle according to an embodiment of the present invention.

Referring to FIG. 1, a vehicle dark current cut-off control system according to an embodiment of the present invention includes a sensing unit 110 and an integrated control unit 120.

The sensing unit 110 measures a state of charge (SOC) of the battery 10 mounted on the vehicle and is a sensor device capable of measuring and detecting the current value or SOC of the battery 10 And outputs information on the measured charge state to the integrated controller 120 to be described later.

The sensing unit 110 may be an intelligent battery sensor (IBS), and may be connected to an integrated controller 120 through a LIN communication or a CAN communication. Also, the sensing unit 110 may be further provided to measure the temperature of the battery 10.

Meanwhile, according to the charge state measured from the sensing unit 110, a process of blocking the dark current of the vehicle is performed by the integrated controller 120, which will be described later.

The integrated control unit 120 is for controlling the starting control of the vehicle and the door opening / closing of the vehicle by blocking the dark current due to the electrical load of the vehicle. Particularly, when the charging state measured by the sensing unit 110 or the starting of the vehicle is off And disconnects the battery 10 from at least one load group of the plurality of load groups 130 according to a predetermined period of time to shut off the dark current.

The integrated control unit 120 may be an intelligent gateway power module (IGPM) function that receives power from the battery 10 at all times and opens and closes the electrical connection between the battery 10 and each load group, And a BCM (Body Control Module) function for performing a start-up control of a vehicle and a door opening / closing operation according to a signal received from the SMK, as well as a SMK (Smart Key Module) . As a result, the power consumption of the battery 10 can be minimized by reducing the power consumption at all times compared with the separate modules, thereby reducing the manufacturing cost.

The plurality of load groups 130, the set time, and the reference value are preset in the integrated control unit 120 for controlling the dark current of the vehicle. Herein, the plurality of load groups 130 may include an in- Are set for each group according to the conditions including the consumption amount of the battery 10, the deterioration of the performance of the vehicle, and the deterioration of the merchantability, and the set time is set according to the elapsed time after the start- And the reference value may be set to a charge state of the battery 10 that should block each load group.

By using this, the integrated control unit 120 can sequentially disconnect the connection between the battery 10 and each load group when the start of the vehicle is turned off, thereby blocking and minimizing the dark current. In the case where the start of the vehicle is turned on The consumption of the battery 10 can be minimized by temporarily releasing the connection between the specific load group and the battery 10. [

For example, when the first set time elapses while the vehicle is in the off-state, the integrated control unit 120 determines an electrical connection between the first load group 131 and the battery 10 among the plurality of load groups 130 Lt; / RTI > At this time, the first set time is 5 seconds to 20 minutes, and the first load group 131 may include an illumination module disposed in a vehicle interior.

When the charging state of the battery 10 is equal to or less than the first reference value after the power of the first load group 131 is shut off or the second set time elapses, The second load group 132 and the battery 10 are disconnected from each other. In this case, the first reference value may be a specific value between 66% and 75%, and the second reference time may be a specific time between 3 and 5 hours.

In addition, the second load group 132 includes a seat module, a rain sensor module, and a multimedia module. In particular, the first load group 131 may include a battery Can be set.

The integrated control unit 120 may be configured such that even if the battery 10 is continuously consumed after the power of the second load group 132 is shut off and the state of charge of the battery 10 is measured below the second reference value, When the third set time elapses due to parking, the electrical connection between the third load group 133 and the battery 10 among the plurality of load groups 130 is released.

In this case, the second reference value may be a specific value of 65% or less, and the third set time may be a specific time between 6 and 8 days.

The third load group 133 includes a clock module, a cluster module, a driver's seat door module DDM, a passenger seat door module ADM, a right rear door module RRDM and a left rear door module RLDM). However, the third load group 133 can reduce the consumption of the battery 10 when the power supply is interrupted. However, since the initialization or the disappearance of the learning data causes the performance and the commerciality to be temporarily degraded, Can be set as loads.

When the vehicle is started or the door is opened or closed in a state where at least one load group among the load groups is blocked, the integrated controller 120 releases the shutoff and connects the battery 10 to the power source . At this time, the integrated control unit 120 can receive information on whether the vehicle is started and whether the door is opened or closed through a car access system (CAS) installed in the vehicle.

When the state of charge of the battery 10 is measured to be equal to or less than the third reference value while the vehicle is running or the ignition is turned on, the integrated control unit 120 determines that the fourth load group 130 of the plurality of load groups 130 The electric connection between the battery 134 and the battery 10 can be temporarily released. At the same time, the integrated control unit 120 outputs a signal to the ECU 20 mounted on the vehicle, so that the ECU 20 drives the ALT (Alternator) 30 to charge the battery 10 of the vehicle .

In addition, the third reference value may be a specific value of 65% or less, and the fourth load group 134 may include an air conditioner module, a heater module, and a heat ray module. The integrated control unit 120 may block the fourth load group 134 when the charged state of the battery 10 is measured to be higher than the third reference value, .

Therefore, the vehicle dark current cut-off control system according to the embodiment of the present invention automatically blocks the load groups according to the charged state of the battery 10 when the start of the vehicle is turned off, It is possible to minimize the dark current generated in the vehicle and to prevent the discharge of the battery 10 and the shortening of its service life.

In addition, the vehicle dark current cut-off control system according to the embodiment of the present invention can temporarily shut off a specific load group according to the charged state of the battery 10 even when the starting of the vehicle is on or running, And shortening of life span can be minimized.

2 is a view for explaining a method for controlling a vehicle dark current cutoff according to an embodiment of the present invention.

Referring to FIG. 2, a method for controlling a vehicle dark current cutoff control in a vehicle dark current cutoff control system according to an embodiment of the present invention will be described.

However, since all the functions performed in the vehicle dark current cut-off control method shown in FIG. 2 are performed in the vehicle dark current cut-off control system described with reference to FIG. 1, all the functions described with reference to FIG. And all functions described with reference to FIG. 2 are performed in the dark current blocking control system for a vehicle according to a preferred embodiment of the present invention.

First, the integrated controller detects the starting state of the vehicle (S110).

At this time, the integrated control unit determines whether the vehicle is parked in a state where the vehicle is not started, or whether the vehicle is turned on and is running.

Next, the integrated control unit measures the state of charge of the battery for blocking the dark current of the vehicle (S120).

If it is determined that the start of the vehicle is turned off, the sensing unit measures the charged state of the battery mounted on the vehicle and outputs the measured state to the integrated control unit (S121). The integrated control unit receives the charging result, The elapsed time is measured (S122).

If it is determined that the vehicle is running while the vehicle is turned on, only the charged state of the battery measured by the sensing unit may be output to the integrated controller without measuring the elapsed time (S123).

Then, based on the result of measuring the charged state of the battery or the elapsed time measured from the sensing unit, the integrated control unit releases the electrical connection between at least one load group and the battery of the plurality of load groups, (S130).

At this time, the integrated control unit compares the elapsed time with a preset first preset time, and when the first set time elapses (S131), the integrated control unit cancels the electrical connection between the first load group and the battery among the plurality of load groups Thereby blocking the dark current caused by the first load group (S132).

Here, the first set time is 5 seconds to 20 minutes, and the first load group may include a lighting module disposed in a vehicle interior. In addition, the integrated control unit continuously receives information on the charged state of the battery from the sensing unit, and determines whether or not another load group is blocked.

When the charging state of the battery measured from the sensing unit is measured to be equal to or less than a predetermined first reference value after the dark current is cut off for the first load group, or when the elapsed time exceeds the second set time (S133), an electrical connection between the second load group and the battery among the plurality of load groups is canceled to block the dark current caused by the second load group, and the information about the state of charge of the battery is continuously received from the sensing unit (S134).

Here, the second set time is a specific time between 3 hours and 5 hours, the first reference value is a specific value between 66% and 75%, and the second load group includes a seat module, a rain sensor module and a multimedia module . ≪ / RTI >

If the charging state of the battery is measured to be less than or equal to the second reference value after the dark current shutoff for the second load group, or if the elapsed time has passed the third set time (S135) The electrical connection between the third load group and the battery among the groups is also released (S136).

Here, the third set time is a specific time between 6 days and 8 days, the second reference value is a specific value of 65% or less, the third load group includes a clock module, a cluster module, , A driver seat door module (DDM), a passenger seat door module (ADM), a right rear door module (RRDM) and a left rear door module (RLDM).

Meanwhile, if the vehicle is running or the ignition is turned on, the integrated control unit may temporarily block a specific load group according to the measured charge state of the battery from the sensing unit (S140).

In this case, if the measured charge state of the battery from the sensing unit is measured to be equal to or less than a predetermined third reference value (S141), the integrated control unit temporarily stores the electrical connection between the fourth load group and the battery of the plurality of load groups temporarily (S142) while the battery is being charged using the ALT (Alternator) mounted on the vehicle.

Here, the third reference value may be a specific value of 65% or less, and the fourth load group may include an air conditioner module, a heater module, and a heat ray module.

When the charging of the battery is progressed and the charging state is measured to be equal to or higher than the third reference value (S143), the integrated control unit releases the blocking of the fourth load group to supply power (S144).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
