[0044] The operating principle and embodiments of the present invention will be described below with reference to the accompanying drawings.
[0045] Figure 1 is a schematic diagram showing an electrical configuration of a vehicle according to an embodiment of the present invention.
[0046] The vehicle may include a body, a chassis, and an electronic assembly 10, wherein the body forms the appearance of the vehicle and accommodates a driver and / or cargo; the chassis has vehicle components other than the body; and the electronic assembly 10 protects the driver and provides convenience for the driver.
[0047] For example, Figure 1 As shown, the electronic component 10 may include an engine management system (EMS) 11, a transmission control unit (TCU) 12, an electronic brake control module (EBCM) 13, a motor-driven power steering (MDPS) device 14, a body control module (BCM) 15, a convenience load 16, a battery sensor 19, and a power management device 100. In addition, a battery B for supplying power to the electronic component 10 may be provided.
[0048] The engine management system 11 may control the operation of the engine in response to an acceleration command from the driver through the accelerator pedal and may manage the engine. For example, the engine management system 11 may perform engine torque control, fuel consumption control, engine fault diagnosis and / or generator control.
[0049] The transmission control unit 12 may control the operation of the transmission or the driving speed of the vehicle in response to a shift command from a driver via a shift lever. For example, the transmission control unit 12 may perform clutch control, shift control, and / or engine torque control during a shift.
[0050] The electronic brake control module 13 can control the electronic brake device of the vehicle in response to the driver's braking command through the brake pedal and maintain the balance of the vehicle. For example, the electronic brake control module 13 can perform automatic parking brake control, anti-skid during braking and / or anti-skid during steering.
[0051] The motor-driven power steering device 14 can assist the driver to easily operate the steering wheel 23a. For example, the motor-driven power steering device 14 can assist the driver's steering operation to reduce the steering force during low-speed driving or parking and increase the steering force during high-speed driving.
[0052] The body control module 15 may control the operation of electronic components for providing convenience to the driver or ensuring the driver's safety. For example, the body control module 15 may control a door lock device, headlights, wipers, electric seats, seat heaters, a combined instrument panel, interior lights, a navigation system, a multi-function switch, etc. installed in the vehicle.
[0053] The convenience load 16 may be a device that provides convenience to the driver. The convenience load 16 may include, for example, an audio device, a heating / ventilation / air conditioning (HVAC) system, a navigation device, a power seat, a seat heater, interior lights, and the like.
[0054] The battery B can store the electric energy generated by the power of the engine and supply power to various electronic components 10 included in the vehicle. For example, when the vehicle is running, the generator can convert the rotational energy of the engine into electric energy, and the battery B can receive the electric energy from the generator and store the electric energy. In addition, the battery B can supply power to the starter motor for starting the engine to drive the vehicle, and can supply power to the electronic components 10 of the vehicle.
[0055] The battery sensor 19 can obtain status information related to the battery B. For example, the battery sensor 19 can measure and output the output voltage of the battery B, the output current of the battery B, the temperature of the battery B, the rated capacity Cb of the battery B, and the like.
[0056] The power management device 100 can obtain the output voltage of battery B, the output current of battery B, the temperature of battery B, the rated capacity Cb of battery B, etc. from the battery sensor 19, and can calculate the state of charge (SOC) of battery B.
[0057] Here, the SOC of battery B may indicate the degree of electric energy stored in battery B. The SOC of battery B generally has a value of 0 to 100%, and may indicate the degree of charge of battery B between a fully discharged state (0%) and a full SOC (100%).
[0058] The power management device 100 can control the generator through the engine management system 11 based on the SOC of battery B. For example, the power management device 100 can increase or decrease the power generation (or power generation voltage) of the generator based on the SOC of battery B. Specifically, the power management device 100 can control the generator so that the SOC of battery B is maintained at a predetermined level or higher.
[0059] The electronic components 10 can communicate with each other through the vehicle communication network NT. For example, the electronic components 10 can send and receive data through Ethernet, Media Oriented Systems Transport (MOST), Flexray, Controller Area Network (CAN), Local Interconnect Network (LIN), etc.
[0060] Figure 2 is a schematic diagram showing the configuration of a power management device according to an embodiment of the present invention.
[0061] like Figure 2 As shown, the vehicle may include a starter motor 11 b , an engine 11 a , a generator 11 c , a battery B, an electronic component 10 , and a power management device 100 .
[0062] The starter motor 11b may supply power to the engine 11a to start the engine 11a when the engine 11a is stopped. The starter motor 11b may receive power from the battery B. Since the starter motor 11b consumes a large amount of power to start the engine 11a, the battery B maintains the SOC at a predetermined level or higher (e.g., the SOC is about 30% or higher) for the operation of the starter motor 11b.
[0063] The generator 11c can generate electrical energy, that is, electricity, by the power of the engine 11a. The engine 11a can generate power using explosive combustion of fuel, and the power of the engine 11a can be transmitted to the wheels through a transmission. At this time, a part of the rotational force generated by the engine 11a can be supplied to the generator 11c, and the generator 11c can generate electricity from the power of the engine 11a.
[0064] The generator 11c may include, for example, a rotor having an excitation coil and a stator having an armature coil. The rotor may be rotated by the rotation of the engine 11a, and the stator may be fixed. When the rotor is rotated by the engine 11a and current is supplied to the excitation coil, a rotating magnetic field is generated, and an induced current is induced in the armature coil due to the rotating magnetic field.
[0065] Thus, the generator 11c can generate electricity. In addition, the size of the magnetic field generated by the rotor can be changed according to the size of the current supplied to the excitation coil, and the size of the induced current generated in the armature coil can be changed. In other words, the amount of power generated by the generator 21e can be controlled according to the size of the current supplied to the excitation coil of the rotor.
[0066] A portion of the power generated by the generator 11c can be supplied to the electronic components 10 of the vehicle, and another portion can be stored in the battery B of the vehicle. In other words, the power generated by the generator 21e can be supplied to the electronic components 10, and the remaining power can be stored in the battery B.
[0067] The battery B can supply power to the starter motor 11b for starting the engine 11a when the engine 11a is stopped, and can supply power to the electronic components 10 of the vehicle. For example, when the power consumption of the electronic components 10 is greater than the power generated by the generator 11c when the vehicle is running, the battery B can supply power to the electronic components 10. The battery B can supply power to the electronic components 10 during parking when the engine 11a is stopped.
[0068] The power management device 100 can obtain the state information of the battery B through the battery sensor 19 , and control the power generation amount of the generator 11 c through the engine management system 11 according to the state information of the battery B.
[0069] Specifically, the battery sensor 19 can collect status information of the battery B, such as the output voltage of the battery B, the output current of the battery B, the temperature of the battery B, and the rated capacity Cb of the battery B. The power management device 100 can receive the status information of the battery B from the battery sensor 19 through the vehicle communication network NT. The power management device 100 can generate a power generation control request for controlling the power generation amount of the generator 11c based on the status information of the battery B. The power management device 100 can send the power generation control request to the engine management system 11 through the vehicle communication network NT, and the engine management system 11 can increase or decrease the power generation amount of the generator 11c in response to the power generation control request of the power management device 100.
[0070] The power management device 100 may include a communicator 130 , a storage device 120 , and a controller 110 .
[0071] The communicator 130 may include a CAN transceiver for receiving a communication signal from the electronic component 10 through a communication network (CNT) and transmitting the communication signal to the electronic component 10 ; and a communication controller for controlling the operation of the CAN transceiver.
[0072] The CAN transceiver may receive communication data from the electronic component 10 through the vehicle communication network NT and output the communication data to the controller 110. The CAN transceiver 111 may receive communication data from the controller 110 and transmit the communication data to the electronic component 10 through the vehicle communication network NT.
[0073] For example, the CAN transceiver can receive the operation information of the generator 11c and the status information of the battery B from the battery sensor 19 through the vehicle communication network NT. In addition, the CAN transceiver can receive information about the power consumption amount, power consumption change amount and operation status from the electronic component 10 through the vehicle communication network NT under certain conditions or periodically.
[0074] For example, the CAN transceiver can send a power generation control request to the engine management system 11 through the vehicle communication network NT, and the engine management system 11 can increase or decrease the power generation of the generator 11c in response to the power generation control request. In addition, the CAN transceiver can send a power limit request to the electronic components 10 through the vehicle communication network NT, and each electronic component 10 can limit power consumption in response to the power limit request.
[0075] The communicator 130 can transmit and receive data to and from the electronic components 10 of the vehicle through the vehicle communication network NT, and the power management device 100 can communicate with the electronic components 10 such as the engine management system 11 and the battery sensor 19 through the communicator 130 .
[0076] The storage device 120 may include a storage medium for storing control data for controlling the power management device 100 and a storage controller for controlling storage / deletion / loading of data stored in the storage medium.
[0077] The storage medium may include a solid state drive (SSD) and a hard disk drive (HDD), etc., and may store various data for managing the SOC of the battery B.
[0078] The storage medium may store power generation information of the generator 11c, charging information of the battery B, and power consumption information of the electronic component 10 received through the communicator 130. Specifically, the storage medium may store information about the operating state and power consumption of each electronic component 10. For example, the storage medium may store information about the operating state and power consumption of each electronic component 10 in the form of a table.
[0079] The storage device 120 may store data in the storage medium according to a storage signal of the controller 110 and output the data stored in the storage medium to the controller 110 according to a load signal of the controller 110. For example, the storage controller may receive a request for the power consumption of each electronic component 10 from the controller 110, and may provide the controller 110 with a reference power consumption table 200 including the operating state and the power consumption of each electronic component 10.
[0080] The controller 110 may include a memory and a processor, wherein the memory is used to store a control program and / or control data for controlling the power management device 100 ; and the processor is used to generate a control signal according to the control program and control data stored in the memory.
[0081] The memory may temporarily store the communication data received through the communicator 130 and / or the storage data stored in the storage device 120. For example, the communication data may include the power generation information of the generator 11c, the charging information of the battery B, and the power consumption information of the electronic component 10 received through the communicator 130. The storage data may include the reference power consumption table 200 including the operation state and the power consumption amount of each electronic component 10.
[0082] The memory may provide the program and / or data to the processor according to a memory control signal of the processor.
[0083] The memory may include volatile memory for temporary storage of data, such as static random access memory (S-RAM) and dynamic random access memory (D-RAM). In addition, the memory may include non-volatile memory for long-term storage of data, such as read-only memory (ROM), erasable programmable ROM (EPROM), and electrically erasable programmable ROM (EEPROM).
[0084] The processor may include various logic circuits and operation circuits, processes data according to a program supplied from the memory, and generates a control signal according to the processing result.
[0085] The processor can control the power generation operation of the generator 11c and the power consumption operation of the electronic component 10 based on the power generation information of the generator 11c, the charging information of the battery B, and the power consumption information of the electronic component 10. For example, based on the power generation amount of the generator 11c and the charging amount of the battery B, the power consumption amount of the electronic component 10 can be calculated by the maximum possible output power that the electronic component 10 can consume.
[0086] In addition, the processor can calculate the available power of the convenience load 16 at the maximum possible output power, excluding the basic power consumption of the necessary electronic components required to drive the engine, steering, braking, etc. The power management device 100 can control the power consumption of the convenience load 16 that provides comfort and convenience to the driver, while the power consumption of the necessary electronic components required to drive the engine, steering, braking, etc. is not controlled by the power management device 100.
[0087] The processor may calculate the amount of power consumption of convenience load 16 based on the power consumption of electronic component 10, and compare the amount of power available for convenience load 16 with the amount of power consumption of convenience load 16. When the amount of power consumption of convenience load 16 is greater than the amount of power available for convenience load 16, the processor may generate a power limit request to reduce the power consumption of convenience load 16.
[0088] The processor may reduce the power consumption of each convenience load 16 according to the operating state of each convenience load 16. For example, the processor may select a convenience load 16 whose power consumption is to be reduced according to the operating state of each convenience load 16, and determine the power consumption of the selected convenience load 16 to be reduced.
[0089] The processor may store a reference power consumption table 200 in the memory, which includes the current operating state and power consumption amount of each convenience load 16. The operating state of the convenience load 16 may include the operating level of the convenience load 16 and / or the driving duty cycle of the convenience load 16. The reference power consumption table 200 of the memory is described in more detail below.
[0090] When the amount of power consumption of convenience load 16 is greater than the available power of convenience load 16, the processor may select convenience load 16 whose power consumption is to be reduced based on reference power consumption table 200 stored in the memory, and determine the power consumption to be reduced of convenience load 16. Selecting convenience load 16 whose power consumption is to be reduced and determining the power consumption to be reduced of convenience load 16 are described in further detail below.
[0091] Therefore, controller 110 may calculate the available power of convenience load 16 and reduce the power consumption of convenience load 16 based on the available power of convenience load 16 .
[0092] A specific method of reducing the power consumption of convenience load 16 based on the power state of the vehicle by power management device 100 will be described below.
[0093] Figure 3 1 is a diagram showing a reference power consumption table representing power consumption based on an operating state of a convenience load, which is stored in a power management device according to an embodiment of the present invention.
[0094] like Figure 3As shown, the power management device 100 may store a reference power consumption table 200 including power consumption amounts based on an operation level and / or a driving duty cycle of the convenience load 16 .
[0095] The columns of the reference power consumption table 200 can represent the power consumption of the same convenient load. Load 1 can have a five-level operating level and can consume 20W (watts) in the first level (stage). Load 1 can further consume 30W in addition to the first level in the second level (stage), and can consume a total of 50W in the second level (stage). Load 1 can further consume 20W in the third level, further consume 10W in the fourth level, and further consume 10W in the fifth level. Load 2 can consume 50W in the first level, consume an additional 20W in the second level, and further consume 20W in the third level.
[0096] In this way, the reference power consumption table 200 may store an increment of power consumption in each row according to an increase in the operation level.
[0097] Convenience loads 16 may have different operating levels. For example, load 1 may have an operating level of five, while load 2 may have an operating level of three.
[0098] Therefore, the reference power consumption table 200 may include spaces. For example, the first row of load 2 is a space ("0"), the second row stores the power consumption of the first level, the third row is a space ("0"), the fourth row is the additional power consumption, and the fifth row stores the additional power consumption of the third level. The position of the space ("0") in the reference power consumption table 200 may be predetermined according to the importance of the corresponding convenience load 16, the power consumption amount of the corresponding convenience load 16, etc.
[0099] The power management device 100 may receive the operation level and power consumption of the convenience load 16 received from the convenience load 16 through the vehicle communication network NT. The power management device 100 may generate a reference power consumption table 200 based on the received operation level and power consumption of the convenience load 16, and may also store the reference power consumption table 200 in the storage device 120. The power management device 100 may store the reference power consumption table 200 in the storage device 120, and may then update the reference power consumption table 200 stored in the storage device 120 based on the operation level and power consumption of the convenience load 16 received through the communication network NT.
[0100] Figure 4 FIG. 1 is a diagram showing a current power consumption table representing current power consumption of a convenience load stored in a power management device according to an embodiment of the present invention.
[0101] like Figure 4As shown, power management device 100 may generate current power consumption table 300 indicating current power consumption of convenience load 16 according to the current operation level and / or duty cycle of convenience load 16 .
[0102] The power management device 100 may generate the current power consumption table 300 based on the reference power consumption table 200 and the current operation level of the convenience load 16 .
[0103] The power management device 100 may search for a column corresponding to the corresponding convenience load 16 among a plurality of columns included in the reference power consumption table 200, and search for a row corresponding to the current operation level of the corresponding convenience load 16. The power management device 100 may generate the current power consumption table 300 based on the power consumption in the column corresponding to the convenience load 16 up to the row corresponding to the current operation level of the corresponding convenience load 16. Specifically, the power management device 100 may input "0" in a row below the row corresponding to the current operation level in the column corresponding to the corresponding convenience load 16.
[0104] For example, when the operation level of load 1 is the third level, Figure 4 As shown, the current power consumption table 300 may include a first row representing the first level of load 1, a second row representing the second level, and a third row representing the third level in the reference power consumption table 200. In addition, "0" may be input in the fourth row representing the fourth level of load 1 of the reference power consumption table 200 and the fifth row representing the fifth level.
[0105] When the operation level of load 2 is the first level, such as Figure 4 As shown, the current power consumption table 300 may include the second row representing the first level of load 2 and the first row smaller than the second row in the reference power consumption table 200. In addition, "0" may be input in the third, fourth and fifth rows of load 2 in the reference power consumption table 200.
[0106] When the operation level of load 3 is the second level, such as Figure 4 As shown, the current power consumption table 300 may include the second row and the first row smaller than the second row representing the second level of the load 3 in the reference power consumption table 200. In addition, "0" may be input in the third, fourth and fifth rows of the load 3 in the reference power consumption table 200.
[0107] When the operation level of load 4 is the second level, such as Figure 4 As shown, the current power consumption table 300 may include the third row representing the second level of the load 4 and the first and second rows smaller than the third row in the reference power consumption table 200. In addition, "0" may be input in the fourth and fifth rows of the load 4 in the reference power consumption table 200.
[0108] The power management device 100 can be based on Figure 4The current power consumption table 300 shown determines that the total power consumption of the convenience load 16 is currently 220W.
[0109] The columns and rows of the current power consumption table 300 may represent priorities of power consumption.
[0110] The left column of the current power consumption table 300 may have the highest priority, and the right column of the current power consumption table 300 may have the lowest priority. For example, the first column of the current power consumption table 300 may have a higher priority than the second column, and the second column may have a higher priority than the third column.
[0111] The upper row of the current power consumption table 300 may have the highest priority, and the lower row of the current power consumption table 300 may have the lowest priority. For example, the first row of the current power consumption table 300 may have a higher priority than the second row, and the second row of the current power consumption table 300 may have a higher priority than the third row.
[0112] Even if the available power of convenience load 16 is less than the power consumption of convenience load 16, higher priority convenience load 16 may maintain the power consumption or may have a slightly reduced power consumption. On the other hand, when the available power of convenience load 16 is less than the power consumption of convenience load 16, lower priority convenience load 16 may significantly reduce the power consumption.
[0113] Figure 5 1 is a diagram showing an example of reducing the power consumption of a convenience load using a current power consumption table stored in a power management device according to an embodiment of the present invention.
[0114] When the available power of the convenience load 16 is less than the power consumption of the convenience load 16, the power management device 100 may select the convenience load 16 whose power consumption is to be reduced based on the current power consumption table 300, and reduce the power consumption of the selected convenience load 16. Specifically, the power management device 100 may select the convenience load 16 whose power consumption is to be reduced based on the arrangement of the rows and columns of the current power consumption table 300, and reduce the power consumption of the selected convenience load 16.
[0115] For example, the current total power consumption of load 1, load 2, load 3, and load 4 may be 220W, while the available power of convenience load 16 may be 140W.
[0116] like Figure 5 As shown, the power management device 100 may add the value from the first row and the first column to the value from the first row and the fourth column of the current power consumption table 300, add the value from the second row and the first column to the value from the second row and the fourth column, and add the value from the third row and the first column to the value from the third row and the fourth column. In other words, the power management device 100 may add the value from the left column to the value from the right column of the upper row, and then add the value from the left column to the value from the right column of the lower row.
[0117] In addition, the power management device 100 can determine whether the sum of the values of each row and column is greater than the available power of the convenience load 16 when adding the values of each row and column of the current power consumption table 300. When the sum of the values of each row and column is greater than the available power of the convenience load 16, the power management device 100 can control the power consumption of the convenience load 16 so that the values of the remaining rows and columns all become "0".
[0118] according to Figure 5 , the value of the first row and the first column of the current power consumption table 300 may be 20, and the sum of the values to the first row and the second column may be 20. Similarly, the sum of the values to the first row and the fourth column may be 30. The sum of the values to the second row and the first column may be 60, the sum of the values to the second row and the second column may be 110, and the sum of the values to the second row and the third column may be 120. In addition, the sum of the values to the second row and the fourth column may be 150.
[0119] The sum of the values of the second row and the fourth column is greater than the available power 140W of the convenience load 16. The power management device 100 can control the power consumption of the convenience load 16 so that the values of the remaining rows and columns starting from the second row and the fourth column all become "0". For example, the power management device 100 can control the load 4 so that the power consumption of the second row and the fourth column of the current power consumption table 300 (i.e., the first level of the load 4) becomes "0". In other words, the power management device 100 can turn off the load 4.
[0120] The power management device 100 may also control the operation level of load 1 to the second level, so that the power consumption in the third row and first column of the current power consumption table 300 (i.e., the third level or higher of load 1) is "0". The power management device 100 may also control the operation level of load 2 to the first level, so that the power consumption in the third row and second column of the current power consumption table 300 (i.e., the second level or higher of load 2) is "0". The power management device 100 may also control the operation level of load 3 to the second level, so that the power consumption in the third row and third column of the current power consumption table 300 (i.e., the third level or higher of load 3) is "0".
[0121] Figure 6 and Figure 7 FIG. 1 is a diagram showing another example of reducing the power consumption of a convenience load using a current power consumption table stored in a power management device according to an embodiment of the present invention.
[0122] The priority of the convenience load 16 may be changed according to the user's convenience load 16. The convenience load 16 that the user has used most recently may have a higher priority.
[0123] Power management apparatus 100 may change the columns of current power consumption table 300 to change (increase) the priority of convenience loads 16 most recently used by the user. In other words, power management apparatus 100 may move the column representing convenience loads 16 most recently used by the user to the leftmost column of current power consumption table 300.
[0124] For example, when the user increases the operation level of the load 3 from the second level to the third level, the power management device 100 may move the power consumption of the load 3 to the first column of the current power consumption table 300, such as Figure 6 The power management device 100 may also move the power consumption of load 1 to the second column and the power consumption of load 2 to the third column.
[0125] In addition, since the operation level of the load 3 becomes level three, the power management apparatus 100 may input “10” to the third row and first column of the current power consumption table 300 based on the reference power consumption table 200 .
[0126] When the available power of convenience load 16 is less than the power consumption of convenience load 16 , power management apparatus 100 may select convenience load 16 whose power consumption is to be reduced based on current power consumption table 300 and reduce the power consumption of the selected convenience load 16 .
[0127] For example, the current total power consumption of load 1, load 2, load 3, and load 4 may be 220W, while the available power of convenience load 16 may be 140W.
[0128] The power consumption of the load 3 most recently operated by the user has a higher priority. The power management apparatus 100 may calculate the sum of all values of the first column representing the power consumption of the load 3 operated by the user, such as Figure 6 Then, the power management device 100 may add the value from the first row and second column to the value from the first row and fourth column, add the value from the second row and second column to the value from the second row and fourth column, and add the value from the third row and second column to the value from the third row and fourth column.
[0129] like Figure 6 As shown, the sum of the first column of the current power consumption table 300 may be 30, and the sum of the values up to the second row and fourth column may be 160. The sum of the values up to the second row and fourth column is greater than the available power of the convenience load 16, 140W. The power management device 100 may control the power consumption of the convenience load 16 so that the values of the remaining rows and columns starting from the second row and fourth column all become "0". For example, the power management device 100 may turn off load 4, control the operation level of load 1 to the second level, and control the operation level of load 2 to the first level. In addition, the power management device 100 may keep the operation level of load 3, which was most recently operated by the user, at the third level.
[0130] When a predetermined reference time (e.g., 5 minutes) has passed since the user operated the convenience load 16, the priority of the convenience load 16 operated by the user is lowered. For example, when a predetermined reference time has passed since the user operated the convenience load 16, and then the available power of the convenience load 16 is less than the power consumption of the convenience load 16, the power management device 100 may select the convenience load 16 whose power consumption is to be reduced, and reduce the power consumption of the selected convenience load 16, such as Figure 5 described.
[0131] In other words, Figure 7 As shown, the power management device 100 can add the value from the first row and the first column to the value of the first row and the fourth column of the current power consumption table 300, add the value from the second row and the first column to the value of the second row and the fourth column, and add the value from the third row and the first column to the value of the third row and the fourth column. When adding the values of the respective rows and columns of the current power consumption table 300, the power management device 100 can determine whether the sum of the values of the respective rows and columns is greater than the available power of the convenience load 16.
[0132] like Figure 7 As shown, the sum of the values of the second row and the fourth column of the current power consumption table 300 may be 150, and the sum of the values of the second row and the fourth column is greater than the available power 140W of the convenience load 16. The power management device 100 may control the power consumption of the convenience load 16 so that the values of the remaining rows and columns starting from the second row and the fourth column all become "0". For example, the power management device 100 may turn off the load 4, control the operation level of the load 1 to the second level, and control the operation level of the load 2 to the first level.
[0133] Figure 8 and Fig. 9 FIG. 1 is a diagram showing another example of reducing the power consumption of a convenience load using a current power consumption table stored in a power management device according to an embodiment of the present invention.
[0134] The priority of the convenience load 16 may be changed according to the user's convenience load 16. The convenience load 16 that the user has used most recently may have a higher priority.
[0135] For example, when the user lowers the operation level of the load 3 from the second level to the first level, the power management device 100 may move the power consumption of the load 3 to the first column of the current power consumption table 300, such as Figure 8 The power management device 100 may also move the power consumption of load 1 to the second column and the power consumption of load 2 to the third column.
[0136] In addition, since the operation level of the load 3 becomes the first level, the power management apparatus 100 may input “0” to the second row and first column of the current power consumption table 300 based on the reference power consumption table 200 .
[0137] When the available power of convenience load 16 is less than the power consumption of convenience load 16 , power management apparatus 100 may select convenience load 16 whose power consumption is to be reduced based on current power consumption table 300 and reduce the power consumption of the selected convenience load 16 .
[0138] The power management apparatus 100 may calculate the sum of all values of the first column representing the power consumption of the load 3 operated by the user, such as Figure 8 Then, the power management device 100 may add the value from the first row and second column to the value from the first row and fourth column, add the value from the second row and second column to the value from the second row and fourth column, and add the value from the third row and second column to the value from the third row and fourth column.
[0139] When a predetermined reference time (eg, 5 minutes) elapses after the user operates the convenience load 16, the priority of the convenience load 16 operated by the user is lowered.
[0140] like Fig. 9 As shown, the power management device 100 can add the values from the first row and first column to the first row and fourth column of the current power consumption table 300, add the values from the second row and first column to the second row and fourth column, and add the values from the third row and first column to the third row and fourth column.
[0141] Fig.10 FIG. 1 is a diagram showing another example of reducing the power consumption of a convenience load using a current power consumption table stored in a power management device according to an embodiment of the present invention.
[0142] The priority of the convenience load 16 may be changed according to the user's convenience load 16. The convenience load 16 that the user has used most recently may have a higher priority.
[0143] For example, Fig.10 As shown, the user can increase the operation level of load 3 from the second level to the third level, and then increase the operation level of load 2 from the first level to the second level.
[0144] The power management device 100 may move the power consumption of load 2 to the first column of the current power consumption table 300, such as Fig.10 The power management device 100 may also move the power consumption of load 3 to the second column and the power consumption of load 1 to the third column.
[0145] In addition, since the operation level of the load 2 changes to the second level, the power management apparatus 100 may input “20” to the first row and third column of the current power consumption table 300 based on the reference power consumption table 200 .
[0146] When the available power of convenience load 16 is less than the power consumption of convenience load 16 , power management apparatus 100 may select convenience load 16 whose power consumption is to be reduced based on current power consumption table 300 and reduce the power consumption of the selected convenience load 16 .
[0147] The power management apparatus 100 may calculate the sum of all values of the first column representing the power consumption of the load 2 operated by the user, such as Fig.10 Then, the power management device 100 may add the value from the first row and second column to the value from the first row and fourth column, add the value from the second row and second column to the value from the second row and fourth column, and add the value from the third row and second column to the value from the third row and fourth column.
[0148] Fig.11 1 is a schematic diagram illustrating a method for reducing power consumption of a convenience load by a power management device according to an embodiment of the present invention.
[0149] Reference Fig.11 , the power management device 100 can generate the current power consumption table 300 (step 1010).
[0150] Power management device 100 may receive the operation level and power consumption of convenience load 16 received from convenience load 16 through vehicle communication network NT. Power management device 100 may generate reference power consumption table 200 based on the received operation level and power consumption of convenience load 16.
[0151] The power management device 100 may also generate a current power consumption table 300 based on the reference power consumption table 200 and the current operation level of the convenience load 16 .
[0152] The power management apparatus 100 may determine whether the user operates the convenience load 16 (step 1020 ).
[0153] For example, the power management apparatus 100 may determine whether the user turns on or off the convenience load 16 or changes the operation level of the convenience load 16 .
[0154] When it is determined that the user does not operate convenience load 16 (No in step 1020 ), power management apparatus 100 may determine whether the power consumption amount of convenience load 16 is greater than the available power of convenience load 16 (step 1030 ).
[0155] The power management device 100 can calculate the available power of the convenience load 16 based on the power generation information of the generator 11 c and the power information of the battery B, and can calculate the power consumption of the convenience load 16 based on the power consumption information of the electronic component 10 .
[0156] The power management device 100 may compare the amount of power consumption of the convenience load 16 with the amount of power available for the convenience load 16 .
[0157] When the power consumption amount of convenience load 16 is not greater than the available power amount of convenience load 16 (No in step 1030 ), power management apparatus 100 may monitor whether the user operates convenience load 16 .
[0158] When the amount of power consumption of convenience load 16 is greater than the amount of power available for convenience load 16 , power management apparatus 100 may reduce the power consumption of convenience load 16 according to the first process (step 1040 ).
[0159] When the available power of convenience load 16 is less than the power consumption of convenience load 16 , power management apparatus 100 may select convenience load 16 whose power consumption is to be reduced based on current power consumption table 300 and reduce the power consumption of the selected convenience load 16 .
[0160] The power management device 100 can sum the values of each row and column according to the predetermined priority of each row and column. For example, the power management device 100 can sum the values of each column in order according to the priority determined by the high priority row, and then sum the values of each column in order according to the priority determined by other low priority rows.
[0161] When summing the values of the respective rows and columns, the power management device 100 may determine whether the sum of the values of the respective rows and columns is greater than the available power of the convenience load 16. When the sum of the values of the respective rows and columns is greater than the available power of the convenience load 16, the power management device 100 may reduce the power consumption of the convenience load 16 corresponding to each remaining row and column.
[0162] When it is determined that the user has operated the convenience load 16 (Yes in step 1020 ), the power management apparatus 100 may update the current power consumption table 300 (step 1050 ).
[0163] The power management apparatus 100 may move the column representing the convenience load 16 most recently used by the user to the leftmost column among the columns of the current power consumption table 300 .
[0164] The power management device 100 may determine whether the amount of power consumption of the convenience load 16 is greater than the amount of power available for the convenience load 16 (step 1060).
[0165] When the power consumption amount of convenience load 16 is not greater than the available power amount of convenience load 16 (No in step 1060 ), power management apparatus 100 may monitor whether the user operates convenience load 16 .
[0166] When the power consumption amount of convenience load 16 is greater than the available power of convenience load 16 (Yes in step 1060 ), power management apparatus 100 may determine whether a predetermined reference time has passed after the user operates convenience load 16 (step 1070 ).
[0167] When the predetermined reference time has not elapsed after the user operates the convenience load 16 (No in step 1070 ), the power management apparatus 100 may reduce the power consumption of the convenience load 16 according to the first process (step 1040 ).
[0168] When a predetermined reference time has elapsed after the user operates the convenience load 16 (Yes in step 1070 ), the power management apparatus 100 reduces the power consumption of the convenience load 16 according to the second process (step 1080 ).
[0169] When the available power of convenience load 16 is less than the power consumption of convenience load 16 , power management apparatus 100 may select convenience load 16 whose power consumption is to be reduced based on current power consumption table 300 and reduce the power consumption of the selected convenience load 16 .
[0170] The power management device 100 may sum the values of the respective rows and columns of the current power consumption table 300 according to a predetermined order, and determine whether the sum of the values of the respective rows and columns is greater than the available power of the convenience load 16. When the sum of the values of the respective rows and columns is greater than the available power of the convenience load 16, the power management device 100 may control the power consumption of the convenience load 16 corresponding to each remaining row and column.
[0171] The power management device 100 may sum the values of each row and column according to the second priority of each row and column that is predetermined. For example, the power management device 100 may sum the values included in the column corresponding to the convenience load 16 currently operated by the user, sum the values of each column in order according to the priority determined by the high priority row, and then sum the values of each column in order according to the priority determined by other low priority rows.
[0172] When summing the values of the respective rows and columns, the power management device 100 may determine whether the sum of the values of the respective rows and columns is greater than the available power of the convenience load 16. When the sum of the values of the respective rows and columns is greater than the available power of the convenience load 16, the power management device 100 may reduce the power consumption of the convenience load 16 corresponding to each remaining row and column.
[0173] As described above, when the available power of convenience load 16 is less than the power consumption of convenience load 16 , power management apparatus 100 may reduce the power consumption of convenience load 16 according to a predetermined priority.
[0174] Fig.12 Schematic diagram showing a method for reducing power consumption by facilitating loads according to an embodiment of the present invention.
[0175] like Fig.12 As shown, convenience load 16 may receive a power consumption reduction request from power management device 100 (step 1110).
[0176] When the available power of convenience load 16 is less than the power consumption of convenience load 16 , power management apparatus 100 may transmit a power consumption reduction request and an operation level to convenience load 16 .
[0177] Convenience load 16 may determine whether power consumption may be reduced (step 1120).
[0178] For example, convenience load 16 may determine whether reducing power consumption would cause convenience load 16 or the vehicle to malfunction, or would cause discomfort to the driver.
[0179] When the power consumption can be reduced (Yes in step 1120), convenience load 16 may reduce the power consumption (step 1130).
[0180] The convenience load 16 may control the operation level to the level received from the power management apparatus 100 .
[0181] Convenience load 16 may determine whether a first time has elapsed (step 1140).
[0182] After the first time has elapsed (Yes in step 1140), convenience load 16 may restore power consumption to the original state (step 1150).
[0183] The convenience load 16 may restore the operating level to the level before the power consumption was reduced.
[0184] Thereafter, the convenience load 16 may send a power consumption recovery signal to the power management device 100 (step 1160).
[0185] When restoring the operation level to the level before the power consumption was reduced, convenience load 16 may notify power management apparatus 100 that the operation level is restored.
[0186] When the power consumption cannot be reduced (No in step 1120 ), the convenience load 16 may transmit a power consumption reduction rejection signal to the power management apparatus 100 (step 1170 ).
[0187] In response to the power consumption reduction rejection signal, the power management apparatus 100 may again select the convenience load 16 whose power consumption is to be reduced in view of the power consumption reduction rejection signal.
[0188] Fig.13 Schematic diagram showing a cooperative operation for reducing power consumption between a power management device and a convenience load according to an embodiment of the present invention.
[0189] Reference Fig.13 , the power management device 100 can send a power consumption reduction request to the convenience load 16 (step 1210).
[0190] In response to the power consumption reduction request, convenience load 16 may reduce power consumption (step 1220).
[0191] After the first time has elapsed, convenience load 16 may resume power consumption (step 1230). The first time may be approximately 10 seconds.
[0192] The convenience load 16 may send a power consumption recovery signal to the power management device 100 (step 1240).
[0193] The power management apparatus 100 may again transmit the power consumption reduction request to the convenience load 16 (step 1250). The power management apparatus 100 may periodically transmit the power consumption reduction request to the convenience load 16.
[0194] In response to the power consumption reduction request, convenience load 16 may reduce power consumption (step 1260).
[0195] When no power consumption restoration signal is received from the convenience load 16 within the second time, the power management device 100 may send a power consumption restoration request to the convenience load 16 (step 1270).
[0196] The second time may be approximately 12 seconds.
[0197] Convenience load 16 may resume power consumption (step 1230).
[0198] In response to the power consumption resumption request of power management apparatus 100 , convenience load 16 may resume power consumption.
[0199] Fig.14 A schematic diagram illustrating a method of controlling a convenience load in a dangerous situation of a power management device according to an embodiment of the present invention.
[0200] Reference Fig.14 , the power management device 100 can calculate the available power of the convenience load 16 (step 1310).
[0201] Power management apparatus 100 may calculate the amount of power consumption of convenience load 16 based on the power consumption information of electronic component 10 .
[0202] The power management device 100 may determine whether the available power of the convenience load 16 is less than “0” (step 1320 ).
[0203] The power management device 100 may compare the available power of the convenience load 16 with “0”.
[0204] When the available power supply amount of convenience load 16 is less than 0 (Yes in step 1320 ), power management device 100 may determine whether the output voltage of battery B is less than the lower limit voltage.
[0205] The lower limit voltage of battery B may be 9V, for example.
[0206] The power management device 100 may compare the output voltage of the battery B with the lower limit voltage.
[0207] When the output voltage of the battery B is less than the lower limit voltage (Yes in step 1330 ), the power management device 100 may enter the power risk mode (step 1340 ).
[0208] Thereafter, the power management device 100 may turn off the convenience load 16 (step 1350 ).
[0209] The power management device 100 may send a load shutoff request to the convenience load 16 .
[0210] When the available power of the convenience load 16 is not less than "0" (No in step 1320) or the output voltage of battery B is not less than the lower limit voltage (No in step 1330), the power management device 100 can determine whether the current state is a power hazard mode (step 1360).
[0211] When the current state is not the power risk mode (No in step 1360 ), the power management device 100 may calculate the available power of the convenience load 16 again.
[0212] When the current state is the power dangerous mode (Yes in step 1360 ), the power management apparatus 100 may release the power dangerous mode (step 1370 ).
[0213] Thereafter, the power management device 100 may turn on the convenience load 16 (step 1380).
[0214] The power management device 100 may send a load-on request to the convenience load 16 .
