Dark current control system and method using a timer {Dark current control system and method using timer}

The present invention relates to a dark current control system and method, and more particularly to a dark current control system and method using a timer.

In general, the electric apparatus using electricity generally turns off the power when the system is turned off. However, when the user turns the system on again later, the system is turned on so that the system can be immediately reacted. The basic configurations for this are continuous current supply, which is called dark current.

For example, in a vehicle, turning off the ignition blocks the flow of current from the battery to various load devices such as starters and radios, while the current from the battery is continuously applied to the supply of current for immediate starting and other controller devices. Will be supplied.

Therefore, if it takes a long time after the vehicle is produced before delivery to the customer, or if the vehicle is not operated for a long time for export, the dark current flows to the load using the battery power (B + power) of the vehicle. There has always been a problem that is discharged.

In order to solve this problem, a method of partially blocking the battery power is conventionally performed. That is, when the junction box 10 is installed between the battery and various load devices as shown in FIG. 1, and the mode switch 12 is installed in the junction box 10, the mode switch 12 is set to ON. Power is supplied from the battery to the load devices, and setting the mode switch 12 to OFF cuts off the power supply from the battery to some load devices (load devices that are not essential for operation, such as multimedia loads).

Conventionally, before the vehicle is delivered to the customer, the mode switch 12 is set to OFF to partially cut off the power supply (induction mode), and when the vehicle is delivered to the customer, the mode switch 12 is set to ON ( After the delivery, all of these tasks were performed manually by the dealer, and the driver often does not know the existence of such a mode switch 12. Therefore, when the vehicle is parked for a long time, a problem of vehicle discharge due to a dark current frequently occurs. It was.

In addition, when the vehicle is shipped on a ship, a person sets the mode switch of the vehicle that is shipped one by one in order to prevent discharge due to dark current during the shipping period of about one month. Many vehicles are missing the mode switch setting, and when the vehicle arrives, complaints of local consumers are caused by the discharge of the vehicle.

In particular, as described above, even when the mode switch is set to OFF, the power to the loads of the vehicle is partially cut off, but the power supply to the junction box itself is not cut off, resulting in current consumption due to the relay coil current of the junction box. Has occurred continuously, when the vehicle is left for a long time, there was also a problem that the discharge of the vehicle occurs.

The problem to be solved by the present invention is that even if a person does not set a mode switch, the power supply to the load can be cut off in order to automatically prevent discharge from the control device of the vehicle, in particular, if the vehicle does not run for a long time The present invention provides a dark current control system and method that can prevent the discharge caused by dark current by blocking the power supplied to the junction box.

3 is a flowchart illustrating a dark current control method according to a preferred embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

2 is a diagram showing the configuration of a dark current control system according to a preferred embodiment of the present invention.

2, a dark current control system 200 according to a preferred embodiment of the present invention includes a first load switching unit 210, a second load switching unit 220, a power switching unit 230, and a wireless receiving unit ( 240, and a control unit 250. In the example illustrated in FIG. 2, two load switching units 210 and 220 are illustrated, but three or more load switching units may be included. In a preferred embodiment of the present invention, the first and second load switching unit (210, 220) and the power switching unit 230 is preferably implemented as a latch relay switch that maintains the switch state even if the power supply is stopped.

The first load switching unit 210 is turned on / off according to the first load switching control signal input from the controller 250 to supply the vehicle power B + to the first load in the on state, and to supply power to the first load in the off state. To block. The first load is a multimedia device such as an audio device inside the vehicle and other loads, which include loads of low importance in the operation of the vehicle.

The second load switching unit 220 is turned on / off according to the second load switching control signal input from the controller 250 to supply the vehicle power B + to the second load in the on state, and to supply power in the off state. To block. The second load includes loads of greater importance than the first loads in the running of the vehicle, such as a ramp inside the vehicle.

The power switching unit 230 provides the vehicle power B + to the components included in the junction box in the on state, and blocks the power B + of the vehicle from being supplied into the junction box in the off state. When the power supply switching unit 230 is turned off to stop the supply of power to the junction box, the control unit 250 also stops operating. The power switching unit 230 is turned off according to a power cut switching control signal input from the control unit 250 in the on state, and in the off state, the door opening signal generated by the door locking device when the user inserts a key into the driver's door and rotates it. Accordingly.

Therefore, when the control unit 250 generates a power off switching control signal to cut off the power supply to the junction box, the current consumption in the vehicle becomes zero until the user opens the driver's door with a key.

On the other hand, the controller 250 generates a first load switching control signal when the first predetermined time (for example, 20 minutes) elapses after the vehicle is driven by using an internal timer to operate the first load switching unit 210. By turning off, the dark current is reduced by interrupting the power supply to the first loads unrelated to vehicle running.

The controller 250 generates a second load switching control signal to generate the second load switching unit 220 when a second predetermined time (eg, 24 hours) elapses after the first time elapses using the internal timer. By turning off, the dark current is controlled by interrupting the power supply to all the loads except the junction box.

The controller 250 generates a power off switching control signal and turns off the power switching unit 230 when a third predetermined time (for example, four weeks) has elapsed, thereby supplying power to the junction box. To control the dark current. At this time, since the power supply to the inside of the junction box is cut off, the control unit 250 is also deactivated because it does not receive power.

In this way, the deactivated control unit 250 is maintained in an inactive state until the user opens the driver's door, and when the user inserts the car key to the driver's door to rotate the door opening signal generated by the door lock device is the power switching unit ( When the 230 is turned on, the power is supplied through the power switch 230 to be activated.

In addition, the controller 250 generates a first and a second load switching control signal and a power-off switching control signal by checking a time elapsed from the last running time using an internal timer, and driving the vehicle over a predefined driving time. In this case, the timer may be reset so that the timer is restarted from the time point at which the vehicle operation ends, and the timer may not be reset when the vehicle is temporarily operated for less than a predetermined time.

For example, the timer is reset and counted after the vehicle is shipped to the ship for export, and after 20 minutes, the first load switching control signal is generated, and after 24 hours, the second load switching control signal is generated. In the event that the power supply to the inlet is sequentially cut off, if a temporary operation of less than 10 minutes has been made in order to arrive at the site and unload the vehicle from the ship, the timer will not reset and will increase again after the end of the running time. When a predetermined power cut-off time (third time, for example, four weeks) has elapsed from the time when the timer is activated when the vehicle is shipped, a power-off switching control signal may be generated to cut off the power supply to the junction box.

In addition, in another preferred embodiment of the present invention, the control unit 250 turns off the load switching units 210 and 220 as time passes, and blocks the power supply to the loads. When starting, or supplying power to the ACCs of the vehicle by inserting a key of the vehicle to supply power to the internal electronics of the vehicle, etc.), the power supply is switched to the load switching units 210 and 220 that are cut off. Supply power. After that, as described above, when the vehicle is driven, the timer is reset or maintains the existing timer setting according to whether the vehicle has been operated for more than the basic driving time, and when the vehicle is not driven and the parking state is maintained again, power supply It returns to the control state just before it became. For example, when the power supply event occurs and disappears while the first load power is cut off and the timer is running for the second time, the first load is cut off again, and the timer is turned toward the second time again. It works.

On the other hand, the wireless receiver 240 receives a wireless control signal of a specific frequency for dark current control and outputs to the control unit 250, the control unit 250 receives a wireless control signal through the wireless receiver 240, the timer is Even before the first to second time has elapsed, the first load switching control signal and the second load switching control signal can be generated to cut off the power supply to the load. Can be generated to control the dark current.

For example, after the vehicle is parked inside the ship for export, and when the control signal is transmitted at a specific frequency inside the ship, the wireless control signal is received by the wireless receiver 240 and output to the controller 250, the controller 250 The power supply to the loads is cut off by generating a first load switching control signal and a second load switching control signal immediately after receiving the control signal according to a preset setting. In addition, the dark current of the vehicle may be controlled by generating a power cutoff switching control signal to cut off the power supply to the junction box.

In addition, the above-described wireless control signal is generated by the user's vehicle remote control is received by the wireless receiver 240, the driver of the vehicle can easily prevent the discharge due to the dark current during long-term parking.

3 is a flowchart illustrating a dark current control method according to a preferred embodiment of the present invention.

It should be noted that the dark current control method illustrated in FIG. 3 is performed in the dark current system 200 described with reference to FIG. 2, and all of the functions of the dark current control system 200 are performed.

Referring to FIG. 3 further, the dark current control system 200 checks whether or not the vehicle is terminated (S310). If the last running time is more than the reference running time, the internal timer is reset, and then the timer operation is started to increase the timer (S331). As described above, since the operation below the reference driving time (for example, the operation of unloading the vehicle from the ship or the vehicle into the store) is a temporary operation rather than a normal operation, the timer is not reset and after the operation is completed, The timer, which was operated on, continues.

On the other hand, after the timer is reset, the dark current control system 200 checks whether a power supply event has occurred, and if a power supply event occurs, proceeds to step S381 to be described later to investigate whether the vehicle has been driven (S332). ).

In the event that no power supply event occurs, the dark current control system 200 checks a timer to determine whether a first time, which is a power supply cutoff setting time to first loads having low relation with a preset vehicle operation, has elapsed. In operation S333, when the first time has elapsed, a first load switching control signal is generated to cut off power supply to the first loads (S335).

After the power supply of the first loads is cut off, the dark current control system 200 checks whether a power supply event has occurred and proceeds to step S370 when a power supply event occurs (S341).

The power supply event is a case where a user starts a vehicle or inserts a vehicle key to supply power to the ACCs of the vehicle in order to supply power to the internal electronic device of the vehicle.

If no power supply event occurs, the dark current control system 200 checks the timer to investigate whether the second time, which is the power supply cutoff setting time to the second loads such as the lamp loads of the vehicle, has elapsed and If the second time has not elapsed, the process proceeds to step S341 to repeat steps S341 to S343 (S343). When the second time has elapsed, the dark current control system 200 generates a second load switching control signal to cut off power supply to the second loads (S345).

After the power supply to the loads is cut off through the above-described process, the dark current control system 200 finally checks whether a power supply event has occurred and proceeds to step S370 when a power supply event occurs. (S351).

If a power supply event does not occur, the dark current control system 200 checks the timer to check whether or not a complete power off set time (third time) into the preset vehicle junction box has elapsed, and the power is cut off. If the time has not elapsed, the process proceeds to step S351 to repeat steps S351 to S353 (S353). When the power-off time has elapsed, the dark current control system 200 generates a power-off switching control signal to cut off power supply to the junction box (S355).

Thereafter, the power supply cutoff state is maintained until the user opens the driver's door using the vehicle key. When the driver's door is opened, as described above with reference to FIG. 2, the power switching unit 230 is turned on to the junction. Power is supplied to the box, and in addition, power may be supplied to loads from which the power supply is cut off (S360).

On the other hand, when a power supply event occurs in the above-described step S341 and step S351, all the switching units that were turned off are set to ON, and power is supplied to the loads from which the power was cut off.

After power is supplied in step S360 or step S370, the dark current control system 200 determines whether the vehicle is driven, and when the vehicle is driven proceeds to step S320 described above (S381) and the vehicle is not driven. If not (for example, after only the internal power is applied by the user, the vehicle is not operated and the parking state is maintained), the process returns to the original control step (S383).

Here, the original control step is a step before the power is supplied. When the power is supplied from step S341 or step S351 to step S370, the control returns to step S335 or step S345, respectively. When the power is supplied from the step S355 to the step S360, the process returns to the step S355.

On the other hand, during the above-described step S320 to step S383, if the wireless control signal is received from the wireless receiver 240, the dark current control system 200 according to the wireless control signal step S335, step S345, and The process may proceed to any one of steps S355. In this case, as described above, the wireless control signal may be transmitted to a place such as an exhibition vessel for export of a ship or a vehicle for sale, may be transmitted from a user's wireless remote controller, and what steps to proceed may be made in advance. It may be set by the user or may be selected by the user. In addition, when proceeding to any one of the above steps, the timer may be set to correspond to the step. For example, when the process proceeds to step S345, the timer may be set immediately after the second time (for example, 24 hours) has elapsed, and the timer may be increased to be sequentially executed from the step S345.

The present invention has been described with reference to the preferred embodiments. Those skilled in the art will appreciate that the present invention can be implemented in a modified form without departing from the essential features of the present invention. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
